entire term of any such agreement or related contracts of a similar nature which
in the aggregate obligate or may obligate University or the Bank in the
aggregate for an amount in excess of $25,000 over the entire term of such
related contracts (the "Contracts"). University has delivered or made available
to IBC true and correct copies of all Contracts. For the purposes of this

repurchase agreements made by, spot foreign exchange transactions of, bankers
acceptances of, agreements with Bank customers for trust services, or deposits
by University or the Bank, but does include unfunded loan commitments and
letters of credit issued by University or the Bank where the borrowers' total
direct and indirect indebtedness to the Bank is in excess of $50,000. Except as
set forth in Schedule 3.16, no participations or loans have been sold which have
buy back, recourse or guaranty provisions which create contingent or direct
liabilities of University or the Bank. To the knowledge of University, all of
the Contracts are legal, valid and binding obligations of the parties to the
Contracts enforceable in accordance with their terms, subject to the effect of
bankruptcy, insolvency, reorganization, moratorium, or other similar laws
relating to creditors' rights generally and to general equitable principles, and
are in full force and effect. To the knowledge of University, except as
described in Schedule 3.16, all rent and other payments by University and the
Bank under the Contracts are current, there are no existing defaults by
University or the Bank under the Contracts and no termination, condition or

of real property leased by it free and clear of all mortgages, pledges, liens,
encumbrances and security interests. Except for deposit accounts entered into
with the Bank in the ordinary course of business or as set forth on Schedule
3.16, neither University nor the Bank is a party to or bound by any contract,
agreement, commitment or understanding with either Shareholder or any Affiliate
of a Shareholder.

                                       12

      SECTION 3.17 RELATED COMPANY TRANSACTIONS. Except as set forth on
Schedules 3.13, 3.14(a), 3.14(b), 3.14(c), 3.15, 3.16 and 3.17, there are no
agreements, instruments, commitments, extensions of credit, tax sharing or
allocation agreements or other contractual agreements of any kind between or
among University, whether on its own behalf or in its capacity as trustee or
custodian for the funds of any employee benefit plan (as defined in ERISA), and
any of its Affiliates (including the Bank). The term "Affiliate" as used in this
Agreement means, with respect to any person, any person that, directly or
indirectly, controls, is controlled by, or is under common control with, such
person in question. For the purposes of this definition, "control" (including,
with correlative meaning, the terms "controlled by" and "under common control
with") as used with respect to any person, shall mean the possession, directly
or indirectly, of the power to direct or cause the direction of the management
and policies of such person, whether through the ownership of voting securities
or by contract or otherwise.

      SECTION 3.18 COMPLIANCE WITH LAWS. Except as set forth on Schedule 3.18,
to the knowledge of University, neither University nor the Bank is in material
default in respect to or is in material violation of (i) any judgment, order,
writ, injunction or decree of any court or (ii) any statute, law, ordinance,
rule, order or regulation of any governmental department, commission, board,
bureau, agency or instrumentality, federal, state or local, including (for
purposes of illustration and not limitation) the Bank Secrecy Act, capital and
FRB reserve requirements, capital ratios and loan limitations of the FRB, the
OCC, the FDIC or the Commissioner. University and the Bank have all permits,
licenses, and franchises from governmental agencies required to conduct their
businesses as they are now being conducted, except where the failure to have any
such permit, license or franchise would not have a Material Adverse Effect.

      SECTION 3.19 INSURANCE. University and the Bank have in effect the
insurance coverage (including fidelity bonds) described in Schedule 3.19 and
have had similar insurance in force for the last 5 years. Except as set forth on
Schedule 3.19, there have been no claims under such fidelity bonds within the
last 5 years and to the knowledge of University no facts exist which would form
the basis of a claim under such bonds. To the knowledge of University, there is
no reason to believe that the existing fidelity coverage would not be renewed by
its carrier on substantially the same terms unless such failure to renew is
based upon any pending claim.

      SECTION 3.20 LOANS. To the knowledge of University, each loan, including,
without limitation, each loan in which the Bank holds a participation interest
(collectively, "Loans") reflected as an asset in the Financial Statements is the
legal, valid and binding obligation of the obligor of each Loan, enforceable in
accordance with its terms, subject to the effect of bankruptcy, insolvency,
reorganization, moratorium, or other similar laws relating to creditors' rights
generally and to general equitable principles; provided, however, that no
representation or warranty is made as to the collectibility of such Loans. All
such Loans were made in the ordinary course of University's business, have been
made in accordance with reasonable and prudent banking practices, and priced
consistently with all other similar Loans of University. University or the Bank
owns each such Loan free and clear of all liens, claims and encumbrances. To the
knowledge of University, the Bank does not have in its portfolio any Loan
exceeding its legal lending limit. Schedule 3.20 sets forth, as of June 30,
1997, a list of all of the Bank's outstanding Loans that were classified as
delinquent, substandard, doubtful, loss, nonperforming or problem Loans in
connection with the Bank's most recent examination or were considered to be so
classified at June 30, 1997 under the Bank's policies and procedures.

      SECTION 3.21 FIDUCIARY RESPONSIBILITIES. To the knowledge of University,
University and the Bank have performed in all respects all of their respective
duties as a trustee, custodian, guardian or as an escrow agent in a manner which
complies in all material respects with all applicable laws, regulations, orders,
agreements, instruments and common law standards, except where the failure to so
perform or comply would not have a Material Adverse Effect.

      SECTION 3.22 PATENTS, TRADEMARKS AND COPYRIGHTS. Except as set forth in
Schedule 3.22, to the knowledge of University, neither University nor the Bank
requires the use of any material patent, patent application, invention, process,
trademark (whether registered or unregistered), trademark application, trade
name, service mark, copyright, or any material trade secret for the business or
operations of University or the Bank. To the knowledge of University, University
and the Bank own or are licensed or otherwise have the right to use the items
listed in Schedule 3.22.

3.23, to the knowledge of University:

      (a) University, the Bank and any property owned or operated by any of them
are in compliance in all respects with all applicable Environmental Laws (as
defined in Section 10.13(c)) and have obtained and are in compliance with all
permits, licenses and other authorizations (individually a "Permit," and
collectively, "Permits") required under any Environmental Law, except where the
failure to obtain or comply would not have a material adverse effect. There is
no past or present event, condition or circumstance that could reasonably be
expected to (1) interfere with the conduct of the business of University or the
Bank in the manner now conducted relating to such entity's compliance with

                                       23
<PAGE>
      SECTION 6.6 EXCLUSIVITY. Prior to the termination of this Agreement in
accordance with the provisions hereof, University shall not solicit, entertain
or negotiate with respect to any offer to acquire University or the Bank from
any other person. During the term of this Agreement, neither University nor the
Bank shall provide information to any other person in connection with a possible
acquisition of University or the Bank (an "Acquisition Proposal"). Immediately
upon receipt of any such unsolicited offer, University will communicate to IBC
the terms of any proposal or request for information and the identity of parties
involved.

      SECTION 6.7 PUBLIC ANNOUNCEMENT. Subject to written advice of counsel with
respect to legal requirements relating to public disclosure of matters related
to the subject matter of this Agreement, the timing and content of any
announcements, press releases or other public statements concerning the proposal
contained herein will occur upon, and be determined by, the mutual consent of
University and IBC.

      SECTION 6.8 EMPLOYEE ISSUES. Within ten (10) days prior to the Closing,
IBC shall be afforded the opportunity to give notice to University, the Bank and
their respective employees as to those employees which are expected to remain
employees of the Surviving Corporation and its Subsidiaries immediately after
the Effective Time, as well the terms of such employees' continued employment
immediately after the Effective Time, which terms may be amended thereafter by
IBC in its sole discretion. IBC presently intends that, except to the extent
that may be required by law, after the Merger, IBC, University and the Bank will
not make additional contributions to the employee benefit plans that were
sponsored by University or the Bank immediately prior to the Merger. IBC agrees
that the employees of University and the Bank who are retained as employees of
IBC or IBC Bank will be entitled to participate as newly hired employees in the
employee benefit plans and programs maintained for employees of IBC and its
affiliates, in accordance with the respective terms of such plans and programs,
and IBC shall take all actions necessary or appropriate to facilitate coverage
of University's and the Bank's employees in such plans and programs from and
after the Effective Time, provided, however, that any preexisting condition
exclusion or waiting period applicable to any health care plan sponsored by IBC
shall be waived with respect to any University or Bank employee. For purposes of
determining each University or Bank employee's benefit for the year in which the
Merger occurs under the IBC vacation or sick leave program, any vacation or sick
leave taken by a University or Bank employee preceding the Effective Time for
the year in which the Merger occurs will be deducted from the total IBC vacation
or sick leave benefits available to such employee for such year.

      SECTION 6.9 ENVIRONMENTAL INVESTIGATION; RIGHT TO TERMINATE AGREEMENT. (a)
IBC and its consultants, agents and representatives, shall have the right, at
IBC's expense, to the same extent that University and the Bank have such right,
but not the obligation or responsibility, to inspect any Property, including,
without limitation, for the purpose of conducting asbestos surveys and sampling,
and other environmental assessments and investigations ("Environmental
Inspections"). IBC's right to conduct Environmental Inspections shall include
the right to sample and analyze air, sediment, soil and groundwater of any
Property to the same extent that University or the Bank have such right. IBC may
conduct such Environmental Inspections at any time subject to Section 6.9(d)
below.

      (b) University and the Bank shall cause to be performed by an
environmental consulting firm acceptable to IBC an environmental investigation
of any Property acquired, leased, foreclosed, managed or controlled by
University or the Bank between the date hereof and the Closing Date, the scope
and results of which shall be acceptable to IBC in its sole discretion.

                                       24
<PAGE>
      (c) University and the Bank shall cause to be performed by an
environmental consulting firm acceptable to IBC a Phase I and, if indicated
thereby, a Phase II environmental investigation of any commercial or
agricultural Property in which University or the Bank acquires a security
interest between the date hereof and the Closing Date in accordance with the
Bank's existing policies and procedures, the results of which investigations(s)
shall be acceptable to IBC.

      (d) IBC shall notify University of any physical inspections of Property
which it intends to conduct, and University may place reasonable restrictions on
the time of such inspections. Upon IBC's notification to University of the
Property upon which it intends to conduct such physical inspections, University
and the Bank shall notify the owner of such Property and use their best efforts
to secure access to such Property for IBC. If, as a result of any such
Environmental Inspection, further investigation ("secondary investigation")
including, without limitation, test borings, soil, water and other sampling is
deemed desirable by IBC, IBC shall notify University of the Properties on which
it intends to conduct a secondary investigation on or prior to the 52nd day
after the date hereof. University and the Bank will provide notification to
owners of Property on which IBC intends to conduct secondary investigations and
will use their commercially reasonable efforts to secure access to such property
for IBC. IBC shall notify University of any Properties that, in the sole
discretion of IBC, are not acceptable and require remediation on or prior to the
45th day after the date hereof.

      (e) Each party hereto agrees to indemnify and hold harmless the other
parties for any claims for damage to the Property or injury or death to persons
in connection with any Environmental Inspection or secondary investigation of
the Property to the extent such damage, injury or death is directly attributable
to the negligent actions or negligent omissions of such indemnifying party. IBC
shall have no liability or responsibility of any nature whatsoever for the
results, conclusions or other findings related to any Environmental Inspection,
secondary investigation or other environmental survey. If this Agreement is
terminated, then except as otherwise required by law, IBC shall have no
obligation to make any reports to any governmental authority of the results of
any Environmental Inspection, secondary investigation or other environmental
survey, but such reporting shall remain the responsibility of and within the
discretion of University. IBC shall have no liability to University or the Bank
for making any report of such results to any governmental authority. If the
Merger is not consummated other than as a result of any breach of any provision
of this Agreement by University and/or the Shareholders, or either of them, IBC
shall reimburse University and the Bank for all reasonable costs and expenses
incurred as a result of any Environmental Inspection conducted at IBC's request.

      (f) IBC shall have the right to terminate this Agreement in any of the
following circumstances:

            (i) the factual substance of any warranties set forth in Section
3.23 is not true and accurate in all material respects irrespective of the
knowledge or lack of knowledge of University or the Shareholders;

            (ii) the Environmental Inspection, secondary investigation or other
environmental survey identifies any past or present violations or potential
violations of Environmental Laws or any event, condition or circumstance that,
based on the estimates of the environmental professionals referred to in this
Section 6.9, may currently or in the future require or result in expenditures in
connection with (1) fines, penalties or other damages, (2) investigation,
remediation

                                       25
<PAGE>
or monitoring of any Controlled Property (including without limitation eventual
removal of asbestos-containing material), (3) preparing and obtaining approval
by the appropriate Environmental Regulatory Authority of remediation plans with
respect to Controlled Properties, or (4) any violations of applicable
Environmental Laws, which expenditures individually or in the aggregate may
exceed $100,000; provided, however, that to the extent such expenditures are
expected to be in excess of $100,000, University may elect to pay or agree to
pay (or to cause the Bank to pay or agree to pay) such excess expenditures, in
which event (a) IBC shall not have the right to terminate this Agreement
pursuant to this paragraph (iii) as a result of such expected expenditures being
in excess of $100,000, and (b) the Merger Consideration to be paid to the
Shareholders pursuant to Article I hereof shall be reduced by the amount by
which such expected expenditures exceed $100,000; or

            (iii) IBC is not permitted to conduct an Environmental Inspection or
secondary investigation of any Property to the extent it deems appropriate.

In the event IBC terminates this Agreement pursuant solely to this Section
6.9(f), neither University nor either of the Shareholders shall have any
liability to IBC pursuant to this Agreement.

      (g) University agrees to make available to IBC and its consultants, agents
and representatives all documents and other material relating to environmental
conditions of the Property including, without limitation, the results of all
other environmental inspections and surveys. University also agrees that all
engineers and consultants who prepared or furnished such reports may discuss
such reports and information with IBC and shall be entitled to certify the same
in favor of IBC and its consultants, agents and representatives in such a manner
which will entitle IBC to rely upon such reports and make all other data
available to IBC and its consultants, agents and representatives. At the written
request of University, IBC agrees to provide University with a copy of all
environmental reports prepared by its consultants as a result of the
Environmental Inspections. IBC shall keep confidential the reports, surveys and
results relating to and of the Environmental Inspections, unless otherwise
required by law.

      SECTION 6.10 SHAREHOLDER CONSENT. University and the Shareholders
acknowledge that the Shareholders have agreed that they will vote the Shares
owned by them in favor of this Agreement and the transactions contemplated
hereby (and/or execute a written consent to such effect), subject to required
regulatory approvals, and that they will retain the right to vote such Shares
during the term of this Agreement

      SECTION 6.11 TERMINATION OF RETIREMENT PLAN. Within 10 days after the date
hereof, University and the Shareholders shall cause the Bank to give notice of
termination of the University Bank Retirement Plan (the "Retirement Plan"),
which notice shall provide for termination 60 days thereafter, and shall use
their reasonable good faith efforts to cause such termination to be effected in
a manner intended to minimize any amounts payable in connection with such
termination or otherwise in connection with such Retirement Plan.

<PAGE>
Board of Directors of University shall have withdrawn or modified in

shall have been a breach of Section 6.6; or (vi) if the shareholders of
University do not approve this Agreement, the Merger Agreement and the Merger;

      SECTION 8.2 EFFECT OF TERMINATION. In the event of the termination and

shall forthwith become void and have no effect, without any liability on the
part of any party or its directors, officers or shareholders, other than the
provisions of Sections 6.9, 8.2, 10.1, 10.8 and 10.14, except that if such
termination shall result (i) from the willful failure of a party to fulfill a
condition to the performance of the obligations of any other party or to perform

<PAGE>
      SECTION 8.5 NON-COMPETITION. In consideration of the benefits of this
Agreement to Allbritton and as a material inducement to IBC to enter into this
Agreement and pay the Merger Consideration, Allbritton hereby covenants and
agrees that, commencing at the Effective Time and ending on the third

Affiliates and representatives not to, directly or indirectly, as proprietor,
partner, stockholder, director, executive, officer, employee, consultant, joint
venturer, investor or in any other capacity, engage in, or own, manage, operate
or control, or participate in the ownership, management, operation or control,
of any entity which engages, directly or indirectly, in the business of banking
(including, without limitation, the solicitation of deposits) within the
territory circumscribed by a fifty-mile radius of any banking premise of the
Bank in existence immediately prior to the Effective Time; provided, however,
the foregoing shall not prohibit either Shareholder from purchasing and holding
as an investment not more than 1% of any class of publicly traded securities of
any entity which conducts the business of banking, so long as such Shareholder
does not participate in any way in the management, operation or control of such
entity; and provided further, however, that the provisions of this sentence

University for any purposes, including, without limitation, to solicit deposits,
loans, or other products or services, all of such lists, records, information

                            SURVIVAL; INDEMNIFICATION

      SECTION 9.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The respective
representations and warranties contained in this Agreement or in any Schedule
delivered pursuant hereto shall survive for a period of two (2) years after the
Effective Time. This Section 9.1 shall not limit any covenant or agreement of
the parties contained in Sections 1.6 or 2.1 of this Agreement which by its
terms contemplates performance after the Effective Time. Further, this Section
9.1 shall not limit any party's obligation to indemnify another party hereunder
if notice of such claim for indemnification generally describing the information
then available regarding the amount and nature of such claim shall have been
given to the party against whom indemnification is sought prior to the
termination of the two-year period described in this Section 9.1.

      SECTION 9.2 INDEMNIFICATION BY ALLBRITTON. Allbritton agrees to indemnify
and hold IBC and its officers, directors, employees, shareholders, Affiliates
and agents harmless from damages, losses, costs or expenses (collectively,
"Damages") suffered or paid, directly or indirectly, through application of the
assets of University, the Bank, IBC, IBC Bank or otherwise, as a result of any
and all claims, demands, suits, causes of action, proceedings, judgments and
liabilities (whether asserted directly or as a common law or statutory claim for
contribution or indemnity), including, without limitation, reasonable counsel
fees and costs incurred in litigation or otherwise, assessed, incurred or
sustained by or against any of them with respect to or arising out of the
failure of any representation or warranty made by the Shareholders, or either of
them, and/or University in this Agreement or in any Schedule delivered pursuant
hereto to be true and correct in

                                       30
<PAGE>
all respects as of the date of this Agreement and as of the Closing Date or the
breach of any covenant made by the Shareholders, or either of them, or by
University hereunder

      SECTION 9.3 INDEMNIFICATION BY IBC. IBC agrees to indemnify and hold the
Shareholders and University harmless from Damages suffered or paid, directly or
indirectly, as a result of any and all claims, demands, suits, causes of action,
proceedings, judgments and liabilities, including reasonable counsel fees
incurred in litigation or otherwise, assessed, incurred or sustained by or
against any of them with respect to or arising out of the failure of any
representation or warranty made by IBC in this Agreement to be true and correct
in all respects as of the date of this Agreement or out of the breach of any
covenant made by IBC hereunder.

      SECTION 9.4 BASKET; LIMIT. A party seeking indemnification (an
"Indemnitee") shall not be entitled to assert any claim for indemnification
under Section 9.2, 9.3 or 9.9(iii) unless and until such time as all claims for
Damages of such Indemnitee arising pursuant to Section 9.2, 9.3 and/or 9.9(iii)
exceed $100,000 in the aggregate (the "Basket"). Once all Damages of an
Indemnitee exceed the Basket, the Indemnitee shall, subject to the terms of this
Article IX, be entitled to full indemnification for all Damages in excess of the
Basket. Further, the maximum amount that an indemnifying party shall be required
to pay under Section 9.2, 9.3 and 9.9(iii) shall be limited to $20,000,000 in
the aggregate. Notwithstanding the foregoing, however, this Section 9.4 shall
not apply with respect to any claim based on any breach of the Shareholders'
and/or University's representations and warranties to the extent such breach
constituted or resulted from a fraudulent action, inaction, statement or
omission under applicable law.

      SECTION 9.5 NOTICE OF CLAIM. If indemnification pursuant to Sections 9.2,
9.3, 9.8 or 9.9 is sought, the Indemnitee shall give notice to the indemnifying
party of an event giving rise to the obligation to indemnify, allow the
indemnifying party to assume and conduct the defense of the claim or action with
counsel reasonably satisfactory to the Indemnitee, and cooperate with the
indemnifying party in the defense thereof; provided, however, that the omission
to give such notice to the indemnifying party shall not relieve the indemnifying
party from any liability which it may have to the Indemnitee, except to the
extent that the indemnifying party is prejudiced by the failure to give such
notice. The Indemnitee shall have the right to employ separate counsel to
represent the Indemnitee if the Indemnitee is advised by counsel that an actual
conflict of interest makes it advisable for the Indemnitee to be represented by
separate counsel and the reasonable expenses and fees of such separate counsel
shall be paid by the indemnifying party. If the party obligated to indemnify and
hold the other harmless wrongfully refuses to assume the defense of the party
seeking indemnification, the party refusing to indemnify shall be responsible
for all legal and other expenses incurred by the other party in connection with
the investigation or defense of such claim or action including, without
limitation, expenses incurred in enforcing such obligation to indemnify.

      SECTION 9.6 SOLE REMEDY. The parties agree that if the Closing occurs,
then the provisions of Article IX shall be the sole basis for recovery as a
result of any failure of a representation or warranty or breach of any covenant
under this Agreement, other than as a result of a breach of Section 1.6 or the
second sentence of Section 6.4, and no party shall have a separate cause of
action for any breach of any representation, warranty or covenant contained
herein; provided, however, that the provisions of this Section 9.6 shall not
limit in any manner any claim any party may have to the extent such claim is
based on fraud.

                                       31
<PAGE>
      SECTION 9.7 ADJUSTMENT OF LIABILITY; CHARACTERIZATION OF INDEMNITY
PAYMENTS. The amount which an Indemnitee shall be entitled to receive from an
indemnifying party under this Article IX with respect to any Damages shall be
net of any insurance recovery by the Indemnitee on account of such Damages from
an unaffiliated party; provided, however, that the foregoing provision shall not
be deemed to impose any obligation on any party to obtain or maintain any
insurance coverage against any risks. Any tax benefit actually realized by an
Indemnitee with respect to any Damages that are fully indemnified by an
indemnifying party shall be paid to the indemnifying party when and if such
benefit is actually realized and then only to the extent such benefit is
attributable to the indemnified portion of such Damages. The benefit actually
realized shall be based on the Federal tax returns of the Indemnitee and any
benefit shall be considered realized when the tax return reflecting such benefit
is filed. In the event such benefit is disallowed or reduced in connection with
any audit, the indemnifying party shall promptly refund to the Indemnitee that
portion of the amount of the benefit previously paid to the indemnifying party
to the extent such benefit is disallowed or reduced. The parties agree to treat
any payment(s) by Allbritton under this Article IX as an adjustment to the
Merger Consideration.

      SECTION 9.8 SPECIAL INDEMNITY BY IBC. IBC agrees to indemnify and hold
harmless the directors, officers, employees, agents and representatives of
University and the Bank for and against any claim, demand, suit, cause of
action, proceeding, judgment, obligation, cost or expense incurred as a result
of any action taken by any of them at the request of IBC pursuant to Section
1.1(b) of this Agreement to approve, facilitate or otherwise cooperate in
authorizing or effecting the Subsequent Merger or the Bank Merger.

      SECTION 9.9 SPECIAL INDEMNITY BY ALLBRITTON. Allbritton agrees to
indemnify and hold IBC, IBC Bank and their respective officers, directors,
employees, shareholders, Affiliates and agents harmless from Damages suffered or
paid, directly or indirectly, through application of the assets of University,
the Bank, IBC, IBC Bank or otherwise, whether before or after the Effective
Time, as a result of any and all claims, demands, suits, causes of action,
proceedings, judgments, obligations and liabilities, including reasonable
counsel fees incurred in litigation or otherwise, assessed, incurred or
sustained by or against any of them with respect to or arising out of (i) the
draft severance policy of the Bank previously made available to IBC, which draft
severance policy University and the Shareholders have represented was never
adopted, (ii) the University Bank Supplemental Executive Retirement Plan, but
only to the extent such Damages with respect to such plan exceed $330,000 in the
aggregate, or (iii) the Early Retirement Option Plan, as that term is defined on
Schedule 3.14, including, without limitation, any taxes, penalties, interest or
fines payable with respect thereto, but only to the extent such Damages with
respect to the Early Retirement Option Plan exceed $50,000 in the aggregate.

                                   ARTICLE X.

                                  MISCELLANEOUS

      SECTION 10.1 EXPENSES. All costs and expenses incurred in connection with
the transactions contemplated by this Agreement, including without limitation,
attorneys' fees, accountants' fees, other professional fees and costs related to
expenses of officers and directors of University and the Bank, shall be paid by
the party incurring such costs and expenses; provided, however, without the
consent of IBC, which consent may be withheld in IBC's sole discretion, all such
costs and expenses incurred by University and the Bank (including expenses

indemnify the other parties hereto against any liability arising from any such
fee or payment incurred by such party;

      SECTION 10.2 BROKERS AND FINDERS. All negotiations on behalf of IBC and
University relating to this Agreement and the transactions contemplated by this
Agreement have been carried on by the parties hereto and their respective agents
directly without the intervention of any other person in such manner as to give
rise to any claim against IBC, Acquisition Sub, University or the Bank for
financial advisory fees, brokerage or commission fees, finder's fees or other
like payment in connection with the consummation of the transactions
contemplated hereby.

      SECTION 10.3 ENTIRE AGREEMENT; ASSIGNMENT. This Agreement, including the
Exhibits and Schedules hereto, (a) constitutes the entire agreement among the
parties with respect to the subject matter hereof and supersedes all other prior
agreements and understandings, both written and oral, among the parties or any
of them with respect to the subject matter hereof, and (b) shall not be assigned
by operation of law or otherwise, provided that IBC may assign its rights and
obligations or those of Acquisition Sub to any direct or indirect, wholly-owned,
subsidiary of IBC, but no such assignment shall relieve IBC of its obligations
hereunder.

      SECTION 10.4 FURTHER ASSURANCES. From time to time as and when requested
by IBC or its successors or assigns, University, the officers and directors of
University, or the Bank, shall execute and deliver such further agreements,

perfect in or to confirm of record or otherwise University's or the Bank's title

reasonably necessary or advisable to carry out the purposes of and effect the
transactions contemplated by this Agreement.

      SECTION 10.5 ENFORCEMENT OF THE AGREEMENT. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof, this being in addition to
any other remedy to which they are entitled at law or in equity.

      SECTION 10.6 SEVERABILITY. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.

      SECTION 10.9 DESCRIPTIVE HEADINGS. The descriptive headings are inserted
for convenience of reference only and are not intended to be part of or to

      SECTION 10.10 PARTIES IN INTEREST. This Agreement shall be binding upon
and inure solely to the benefit of each party hereto, and nothing in this
Agreement, express or implied, is intended to confer upon any other person any
rights or remedies of any nature whatsoever under or by reason of this

      SECTION 10.11 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which

      SECTION 10.12 INCORPORATION BY REFERENCE. Any and all schedules, exhibits,

      SECTION 10.13 CERTAIN DEFINITIONS.

      (a) "Subsidiary" or "Subsidiaries" shall mean, when used with reference to
an entity, any corporation, a majority of the outstanding voting securities of
which are owned directly or indirectly by such entity or any partnership, joint
venture or other enterprise in which any entity has, directly or indirectly, any
equity interest.

      (b) "Material Adverse Effect" shall mean any circumstance, event or series
of events which has a material adverse effect on the financial condition,
assets, liabilities (absolute, accrued, contingent or otherwise), reserves,
business or results of operations of University and the Bank, taken as a whole
(or when the reference is to IBC, to IBC and its Subsidiaries, taken as a
whole).

      (c) "Environmental Laws" shall mean all federal, state and local laws,
ordinances, rules, regulations, guidance documents, directives, and decisions,
interpretations and orders of courts or administrative agencies or authorities,
relating to the release, threatened release, recycling, processing, use,
handling, transportation treatment, storage, disposal, remediation, removal,
inspection or monitoring of Polluting Substances or protection of human health
or safety or the environment (including, without limitation, wildlife, air,
surface water, ground water, land surface, and subsurface strata), including,
without limitation, the Comprehensive Environmental Response Compensation and
Liability Act of 1980, as amended ("CERCLA"), the Superfund Amendments and
Reauthorization Act of 1986, as amended ("SARA"), the Resource Conservation and
Recovery Act of 1976, as amended ("RCRA"), Hazardous and Solid Waste Amendments
of 1984, as

                                       35
<PAGE>
amended ("HSWA"), the Hazardous Materials Transportation Act, as amended
("HMTA"), the Toxic Substances Control Act ("TSCA"), Occupational Safety and
Health Act ("OSHA"), Federal Water Pollution Control Act, Clean Air Act, and any
and all regulations promulgated pursuant to any of the foregoing.

      (d) "Polluting Substances" shall mean those substances included within the

TSCA, OSHA, and/or any other Environmental Laws, as amended, and shall include,
without limitation, any material, waste or substance which is or contains
explosives, radioactive materials, oil or any fraction thereof, asbestos, or
formaldehyde. To the extent that the laws or regulations of the State of Texas
establish a meaning for "hazardous substance," "hazardous waste," "hazardous
materials," "solid waste," or "toxic waste," which is broader than that
specified in any of CERCLA, SARA, RCRA, HSWA, HMTA, TSCA, OSHA or other
Environmental Laws such broader meaning shall apply.

      (e) "Release" shall mean any spilling, leaking, pumping, pouring,

individual is actually aware of such fact or other matter, or (ii) such
individual ought reasonably to be aware of such fact or other matter in the
prudent exercise of his or her duties and responsibilities. University shall be
deemed to have "knowledge" of or to have "known" a particular fact or other
matter if Allbritton, Lawrence I. Hebert, Randall Reeves or Wayne Walker has
knowledge of such fact or other matter. IBC shall be deemed to have "knowledge"
of or to have "known" a particular fact or other matter if Dennis E. Nixon, R.
David Guerra or Carlos A. Martinez has knowledge of such fact or other matter.

      SECTION 10.14 ARBITRATION. The parties shall submit to binding arbitration
by a panel of three arbitrators any disputed question or controversy arising
under this Agreement or arising out of or relating to the transactions
contemplated by the Agreement (whether based on contract, tort or any other
basis). Any such arbitration shall be conducted at Houston, Texas. Either party
may initiate the arbitration, by notice in writing to the other party, setting
forth the nature of the dispute, the amount involved, if any, and the remedy
sought. Any party desiring to initiate arbitration shall serve a written notice
of intention to arbitrate to the other party and to the American Arbitration
Association office in Dallas, Texas (or the city located in Texas that is
closest to Dallas) within 180 days after dispute has arisen. A dispute is deemed
to have arisen upon receipt of written demand or service of judicial process.
Failure to serve a notice of intention to arbitrate within the time specified
above shall be deemed a waiver of the notifying party's right to compel
arbitration of such claim. Such notice of intention to arbitrate may be informal
and need not comply with Rule 6 of the American Arbitration Association. Legal
action regarding this Agreement and any liabilities hereunder shall either be
brought by arbitration, as described herein, or by judicial proceedings-but
shall not be pursued in different or alternative forums. The issue of waiver
pursuant to this paragraph is an arbitrable issue.

      The panel of three arbitrators shall be appointed promptly upon filing of
the complaint in arbitration by the initiating party, and shall be selected from
the Commercial Arbitration Panel in accordance with the Commercial Arbitration
Rules of the American Arbitration Association. All of the arbitrators shall be
members of the American Arbitration Association, and, if commercially

                                       36
<PAGE>
reasonable, at least two of the arbitrators shall be experienced in the banking
industry. Depositions may be taken and other discovery obtained in any
arbitration under this Agreement. The panel of arbitrators appointed hereunder
shall conduct the arbitration pursuant to the Commercial Arbitration Rules of
the American Arbitration Association then in effect, except as such rules may be
modified for the purpose of the arbitration proceeding by mutual written
agreement of the parties to this Agreement.

      In the arbitration proceeding subject to these provisions, the
arbitrators, or a majority of them, are specifically empowered to decide (by
documents only, or with a hearing, at the arbitrators sole discretion)
pre-hearing motions which are substantially similar to prehearing motions to
dismiss and motions for summary adjudication.

      The award of the arbitrators shall be final and binding upon the parties
and judgment thereon may be entered in any court having jurisdiction.

      All statutes of limitations which would otherwise be applicable shall
apply to any arbitration proceeding hereunder, provided, however, that the
filing of a complaint in arbitration shall serve to toll such statutes of
limitation to the same extent as they would be tolled if an action had been
filed in a court of competent jurisdiction.

      The provisions of this Section 10.14 shall survive any termination,
amendment, or expiration of the Agreement in which this section is contained,
unless all the parties hereto otherwise expressly agree in writing.

      The parties acknowledge that this Agreement evidences a transaction
involving interstate commerce. The Federal Arbitration Act shall govern the
interpretation, enforcement, and proceedings pursuant to the arbitration clause
in this Agreement.

      The arbitrators, or a majority of them, shall award attorney's fees and
costs to the prevailing party pursuant to the terms of this Agreement.

      Venue of any arbitration proceeding hereunder will be in Harris County,
Texas.

Except as set forth above concerning awards to the prevailing party, each party
shall bear its own expenses in connection with preparation for the presentation
of its case at the arbitration proceedings and the fees and expenses of the
arbitrators and all other expenses of the arbitration (except those referred to
in the preceding sentence) shall be borne equally by the parties to such
arbitration.
