1.       Representations And Warranties Of The Company.
         ---------------------------------------------

         The Company represents and warrants to each of the Underwriters as
follows:

         (a)      A registration statement on Form S-3, as amended (File No.
                  333-119345), with respect to the Shares has been prepared by
                  the Company in conformity with the requirements of the
                  Securities Act of 1933 (the "Act") and the rules and
                  regulations (the "Rules and Regulations") of the Securities
                  and Exchange Commission (the "Commission") thereunder and has
                  been filed with the Commission. The Company has complied with
                  the conditions for the use of Form S-3. Copies of such
                  registration statement, including any amendments thereto, the
                  preliminary prospectus (meeting the requirements of the Rules
                  and Regulations) contained therein and the exhibits, financial
                  statements and schedules, as finally amended and revised, have
                  heretofore been delivered by the Company to you. Such
                  registration statement, together with any registration
                  statement filed by the Company pursuant to Rule 462(b) of the
                  Act, herein referred to as the "Registration Statement," has
                  become effective under the Act and no post-effective amendment
                  to the Registration Statement has been filed as of the date of
                  this Agreement. The Company will file with the Commission a
                  prospectus supplement (the "Prospectus Supplement") relating
                  to the Shares pursuant to Rule 424 or Rule 434 under the Act.
                  The term "Prospectus" means the form of final prospectus
                  included in the Registration Statement at the time it became
                  effective under the Act, as amended and supplemented prior to
                  the date of this Agreement and as supplemented by the
                  Prospectus Supplement, and shall be deemed to include the
                  "electronic Prospectus" for use in connection with the
                  offering of the Shares contemplated by Section 3 of this
                  Agreement. Any reference herein to the Registration Statement,
                  any preliminary prospectus or the Prospectus shall be deemed
                  to refer to and include the documents incorporated or deemed
                  to be incorporated by reference therein pursuant to Item 12 of
                  Form S-3 that were filed under the Securities Exchange Act of
                  1934 (the "Exchange Act"), on or before the effective date of
                  the Registration Statement or the date of such preliminary
                  prospectus or any Prospectus, as the case may be. All
                  references in this Agreement to the Registration Statement,
                  any preliminary prospectus or the

                                       2


                  Prospectus, or any amendments or supplements to the foregoing,
                  shall include the copy thereof filed with the Commission
                  pursuant to its Electronic Data Gathering, Analysis and
                  Retrieval System ("EDGAR"). Any reference herein to the terms
                  "amend," "amendment" or "supplement" with respect to the
                  Registration Statement or the Prospectus shall be deemed to
                  refer to and include the filing of any document under the
                  Exchange Act after the effective date of the Registration
                  Statement, or the date of any preliminary prospectus or the
                  Prospectus, as the case may be, and deemed to be incorporated
                  therein by reference.

         (b)      The Commission has not issued an order preventing or
                  suspending the use of any Prospectus relating to the proposed
                  offering of the Shares nor instituted proceedings for that
                  purpose. The Registration Statement contains, and the
                  Prospectus and any amendments or supplements thereto will
                  contain, all statements that are required to be stated therein
                  by, and will conform to, the requirements of the Act and the
                  Rules and Regulations. Any Prospectus filed by electronic
                  transmission by EDGAR (except as may be permitted by
                  Regulation S-T under the Act) will be identical to the copies
                  thereof delivered to the Underwriters for use in connection
                  with the offer and sale of the Shares. The Registration
                  Statement at the time it became effective under the Act and
                  any post-effective amendment thereto did not contain any
                  untrue statement of a material fact and did not omit to state
                  any material fact required to be stated therein or necessary
                  to make the statements therein not misleading. The
                  Registration Statement, the Prospectus and any amendments and
                  supplements thereto do not contain, and will not contain, any
                  untrue statement of material fact; and do not omit, and will
                  not omit, to state any material fact required to be stated
                  therein or necessary to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading; provided, however, that the Company makes no
                  representations or warranties as to information contained in
                  or omitted from the Registration Statement or the Prospectus,
                  or any such amendment or supplement, in reliance upon, and in
                  conformity with, written information furnished to the Company
                  by or on behalf of any Underwriter through the Representative,
                  specifically for use in the preparation thereof. There are no
                  contracts or documents that are required to be filed as
                  exhibits to the Registration Statement or described in the
                  Registration Statement or the Prospectus that are not so filed
                  or described as required, and such contracts and documents as
                  are summarized in the Registration Statement or the Prospectus
                  are fairly summarized in all material respects.

         (c)      The documents that are incorporated by reference into the
                  Registration Statement or the Prospectus or from which
                  information is so incorporated by reference, when they became
                  effective or were filed with the Commission, as the case may
                  be, complied in all material respects with the requirements of
                  the Exchange Act and the rules and regulations of the
                  Commission thereunder; and any documents so filed and
                  incorporated by reference subsequent to the date hereof shall,
                  when they are filed with the Commission, conform in all
                  material respects with the requirements of the Exchange Act
                  and the rules and regulations of the Commission thereunder.

                                       3


         (d)      This Agreement has been duly authorized, executed and
                  delivered by the Company, and constitutes a valid, legal and
                  binding obligation of the Company, enforceable in accordance
                  with its terms, except as rights to indemnity hereunder may be
                  limited by Federal or state securities laws and except as such
                  enforceability may be limited by bankruptcy, insolvency,
                  reorganization or similar laws affecting the rights of
                  creditors generally, and subject to general principles of
                  equity. The Company has full power and authority to enter into
                  this Agreement and to authorize, issue and sell the Shares as
                  contemplated by this Agreement.

         (e)      The Forward Agreement has been duly authorized, executed and

                  with its terms, except as rights to indemnity thereunder may
                  be limited by Federal or state securities laws and except as
                  such enforceability may be limited by bankruptcy, insolvency,
                  reorganization or similar laws affecting the rights of
                  creditors generally, and subject to general principles of
                  equity. The Company has full power and authority to enter into
                  the Forward Agreement and to authorize, issue and sell the
                  Shares as contemplated by the Forward Agreement.

         (f)      The Stock Purchase Agreement, dated as of October 15, 2004
                  (the "Antioch Stock Purchase Agreement"), by and among the
                  Company, Antioch Holding Company ("Antioch") and the
                  shareholders of Antioch named therein has been duly
                  authorized, executed and delivered by the Company and
                  constitutes a valid and binding obligation of the Company,
                  enforceable against the Company in accordance with its terms,
                  except as such enforceability may be limited by bankruptcy,
                  insolvency, reorganization or similar laws affecting the
                  rights of creditors generally, and subject to general
                  principles of equity. True, correct and complete copies of the
                  Antioch Stock Purchase Agreement and the other material
                  documents, agreements, certificates or other instruments
                  executed or delivered in connection therewith have been made
                  available to the Underwriters. The Antioch Stock Purchase
                  Agreement conforms in all material respects to the statements
                  relating thereto contained in the Registration Statement and
                  the Prospectus or incorporated by reference therein.

                  with its terms, except as such enforceability may be limited
                  by bankruptcy, insolvency, reorganization or similar laws
                  affecting the rights of creditors generally, and subject to
                  general principles of equity. True, correct and complete
                  copies of the First Northwest Merger Agreement and the other

                  company, corporation, limited liability company or national
                  banking association and has been duly incorporated or

                  in each other jurisdiction in which it owns or leases real
                  property or in which the conduct of its business makes such
                  qualification necessary and in which the failure to so qualify
                  would, individually or in the aggregate, have a material
                  adverse effect on the condition (financial or otherwise),
                  properties, assets,

                  transactions in the ordinary course of business (a "Material
                  Adverse Effect"). All of the issued and outstanding shares of
                  capital stock of or other equity interests in the Subsidiaries
                  (A) have been duly authorized and are validly issued, (B) are

                  or transfer, preemptive rights, claim or equity; and, except
                  as disclosed in the Prospectus, no options, warrants or other
                  rights to purchase, agreements or other obligations to issue
                  or other rights to convert any other obligations into shares
                  of capital stock or ownership interests in the Subsidiaries
                  are outstanding.

         (i)      Except as contemplated by the Prospectus, subsequent to the
                  respective dates as of which information is given in the
                  Registration Statement and the Prospectus, neither the Company
                  nor any of the Subsidiaries has incurred any material
                  liabilities or obligations, direct or contingent, or entered
                  into any material transactions, other than in the ordinary
                  course of business, or declared or paid any dividends or made
                  any distribution of any kind with respect to its capital
                  stock; and there has not been any change in the capital stock
                  (other than a change in the number of outstanding shares of
                  Common Stock due to the issuance of shares upon the exercise
                  of outstanding options, warrants, shares issued under the
                  Company's employee stock purchase plan or the Directors
                  Deferred Fee & Stock Plan or shares issued pursuant to the
                  Company's acquisition of Town Bankshares, Ltd.), or any
                  material change in the short-term or long-term debt (other
                  than the issuance of $50.0 million of trust preferred
                  securities contemplated by the Prospectus), or any issuance of
                  options, warrants, convertible securities or other rights to
                  purchase the capital stock, of the Company or any of the
                  Subsidiaries, or any Material Adverse Effect, or any
                  development involving a prospective Material Adverse Effect.

         (j)      The outstanding shares of Common Stock have been duly
                  authorized and validly issued and are fully paid and
                  non-assessable; the Shares to be purchased by the Forward
                  Seller pursuant to the Forward Agreement, whether pursuant to
                  physical settlement, as a result of acceleration or otherwise,
                  have been duly authorized and when issued, delivered and paid
                  for as contemplated by the Forward Agreement, will be validly
                  issued, fully paid and non-assessable; and no preemptive
                  rights of shareholders exist with respect to any of the Shares
                  or the issue and sale thereof. The Company has reserved and
                  will keep available, free from preemptive and other similar
                  rights, out of its authorized but unissued Common Stock,
                  solely for the purpose of issuance upon settlement of the
                  transactions contemplated by the Forward Agreement as therein
                  provided, the full number of Shares as shall then be issuable
                  upon settlement of such transactions. Neither the filing of
                  the Registration Statement nor the offering or sale of the
                  Shares as contemplated by

                                       6


                  this Agreement gives rise to any rights, other than those that
                  have been waived or satisfied, for or relating to the
                  registration of any shares of Common Stock.

         (k)      If the Company issues and sells shares of Common Stock to the
                  Underwriters pursuant to Section 13 hereof, the Shares to be
                  purchased by the Underwriters from the Company will have been
                  duly authorized for issuance and sale to the Underwriters
                  pursuant to this Agreement and, when issued and delivered by
                  the Company pursuant to this Agreement against payment of the
                  consideration set forth herein, will be validly issued and
                  fully paid and non-assessable.

         (l)      The information set forth under the caption "Capitalization"
                  in the Prospectus is true and correct as of the date thereof.
                  All of the Shares conform to the description thereof contained
                  or incorporated by reference in the Registration Statement.
                  The form of certificate for the Shares conforms to the
                  corporate law of the jurisdiction of the Company's
                  incorporation. Immediately after the sale of the Shares to the
                  Underwriters, no shares of the Company's preferred stock,
                  without par value (the "Preferred Stock"), shall be issued and
                  outstanding and no holder of any shares of capital stock,
                  securities convertible into or exchangeable or exercisable for
                  capital stock or options, warrants or other rights to purchase
                  capital stock or any other securities of the Company shall
                  have any existing or future right to acquire any shares of
                  Preferred Stock other than pursuant to the Rights Agreement.
                  No holders of securities of the Company have rights to the
                  registration of such securities under the Registration
                  Statement that have not been waived.

         (m)      The Company has not distributed and will not distribute any
                  prospectus or other offering material (including, without
                  limitation, content on the Company's website that may be
                  deemed to be a prospectus or other offering material) in
                  connection with the offering and sale of the Shares other than
                  any preliminary prospectus or the Prospectus or other
                  materials permitted by the Act to be distributed by the
                  Company.

         (n)      The consolidated financial statements of the Company and its
                  subsidiaries, together with related notes and schedules as set
                  forth or incorporated by reference in the Registration
                  Statement and the Prospectus, present fairly the financial
                  position and the results of operations and cash flows of the
                  Company and its consolidated subsidiaries, at the indicated
                  dates and for the indicated periods. Such financial statements
                  and related schedules have been prepared in accordance with
                  U.S. generally accepted principles of accounting, consistently
                  applied throughout the periods involved, except as disclosed
                  therein, and all adjustments necessary for a fair presentation
                  of results for such periods have been made other than normal,
                  recurring adjustments. The summary financial and statistical
                  data included or incorporated by reference in the Registration
                  Statement and the Prospectus presents fairly the information
                  shown therein and such data has been compiled on a basis
                  consistent with the financial statements presented therein and
                  the books and records of the Company. There are no pro forma
                  financial statements or other pro forma financial information
                  required to be included or

                                       7


                  incorporated by reference in the Registration Statement or the
                  Prospectus. No other financial statements or schedules of the
                  Company are required by the Act or the Rules and Regulations,
                  or the Exchange Act or the rules and regulations of the
                  Commission thereunder to be included or incorporated by
                  reference in the Registration Statement or the Prospectus.
                  Prior to the issuance of shares of Common Stock upon
                  settlement of the Forward Agreement, the Forward Agreement
                  will be reflected in the Company's diluted earnings per share
                  calculations using the treasury stock method. The Company
                  expects that there will be no dilutive effect on the Company's
                  earnings per share except during periods when the average
                  market price of the Common Stock is above the per share
                  adjusted forward sale price under the Forward Agreement.

         (o)      The Company maintains a system of internal accounting controls
                  sufficient to provide reasonable assurances (i) regarding the
                  reliability of financial reporting and the preparation of
                  financial statements for external purposes in accordance with
                  general accepting accounting principles and (ii) that (A)
                  transactions are executed in accordance with management's
                  general or specific authorization; (B) transactions are
                  recorded as necessary to permit preparation of financial
                  statements in conformity with generally accepted accounting
                  principles and to maintain accountability for assets; (C)
                  access to assets is permitted only in accordance with
                  management's general or specific authorization; and (D) the
                  recorded accountability for assets is compared with existing
                  assets at reasonable intervals and appropriate actions is
                  taken with respect to any differences. The certifications of
                  the Company's Chief Executive Officer and Chief Financial
                  Officer filed as exhibits to the Company's quarterly report on
                  Form 10-Q for the quarter ended September 30, 2004, pursuant
                  to Sections 302 and 906 of the Sarbanes-Oxley Act, were
                  accurate, in all material respects, as of the date such
                  certifications were made, and, to the knowledge of the
                  Company, such certifications are accurate in all material
                  respects as of the date hereof.

         (p)      Based on the evaluation of its disclosure controls and
                  procedures, the Company is not aware of (i) any significant
                  deficiency or material weakness in the design or operation of
                  internal control over financial reporting that are reasonably
                  likely to adversely affect the Company's ability to record,
                  process, summarize and report financial information or (ii)
                  any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  Company's internal control over financial reporting. There
                  have been no changes in internal control over financial
                  reporting during the Company's most recent fiscal quarter that
                  have materially affected or are reasonably likely to
                  materially affect the Company's internal control over
                  financial reporting.

         (q)      Ernst & Young LLP (the "Accountant"), which has certified
                  certain financial statements of the Company and delivered its
                  opinion with respect to the audited financial statements and
                  schedules included in the Registration Statement and the
                  Prospectus, are independent public accountants with respect to
                  the Company within the meaning of the Act and the Rules and
                  Regulations. The Company has not engaged the Accountant to
                  provide any services to the Company that are

                                       8


                  impermissible under the Exchange Act, except as permissible
                  under the Exchange Act at the time such services were
                  provided. All such services have been approved by the Audit
                  Committee of the Company's Board of Directors as required by
                  the Exchange Act.

         (r)      There is no action, suit, claim or proceeding pending or, to
                  the knowledge of the Company, threatened against the Company
                  or any of the Subsidiaries before any court or administrative
                  agency or otherwise that if determined adversely to the
                  Company or any of its Subsidiaries might have a Material
                  Adverse Effect or prevent the consummation of the transactions
                  contemplated hereby, except as set forth in the Registration
                  Statement and the Prospectus.

         (s)      No labor problem or dispute with the employees of the Company
                  or the Subsidiaries exists or, to the Company's knowledge, is
                  threatened or imminent, that could have a Material Adverse
                  Effect.

         (t)      The Company and the Subsidiaries have good and marketable
                  title to all of the properties and assets reflected in the
                  financial statements (or as described in the Registration
                  Statement) hereinabove described, subject to no lien,
                  mortgage, pledge, charge or encumbrance of any kind except
                  those reflected in such financial statements (or as described
                  in the Registration Statement) or that are not material in
                  amount or that do not materially interfere with the use made
                  or proposed to be made of such property or assets. The Company
                  and the Subsidiaries occupy their leased properties under
                  valid and binding leases conforming in all material respects
                  to the description thereof set forth in the Registration
                  Statement and the Prospectus.

         (u)      The Company and the Subsidiaries have filed all Federal,
                  state, local and foreign tax returns that have been required
                  to be filed and have paid all taxes indicated by said returns
                  and all assessments received by them or any of them to the
                  extent that such taxes have become due and are not being
                  contested in good faith and for which an adequate reserve for
                  accrual has been established in accordance with U.S. generally
                  accepted accounting principles, except where the failure to so
                  file would not have a Material Adverse Effect. All tax
                  liabilities have been adequately provided for in the financial
                  statements of the Company, and the Company does not know of
                  any actual or proposed additional material tax assessments.
                  There are no transfer taxes or other similar fees or charges
                  under Federal law or the laws of any state, or any political
                  subdivision thereof, required to be paid by the Company in
                  connection with the execution and delivery of this Agreement
                  or the issuance by the Company or sale by the Company of the
                  Shares.

         (v)      Since the respective dates as of which information is given in
                  the Registration Statement and the Prospectus, there has not
                  been any material adverse change or any development involving
                  a prospective change that has had or is reasonably likely to
                  have a Material Adverse Effect, whether or not occurring in
                  the ordinary course of business, and there has not been any
                  material transaction entered into or any material transaction
                  that is probable of being entered into by the Company or

                                       9


                  the Subsidiaries, other than transactions in the ordinary
                  course of business and changes and transactions described in
                  the Registration Statement and the Prospectus, as it may be
                  amended or supplemented. The Company and the Subsidiaries have
                  no material contingent obligations that are not disclosed in
                  the Company's financial statements in the Registration
                  Statement and the Prospectus.

         (w)      Neither the Company nor any of the Subsidiaries is or, with
                  the giving of notice or lapse of time or both, will be in
                  violation of or in default under (i) any agreement, lease,
                  contract, indenture or other instrument or obligation to which
                  it is a party or by which it, or any of its properties, is
                  bound and which default has had or is reasonably likely to
                  have a Material Adverse Effect or (ii) its respective charter
                  ("Charter"), by-laws ("By-laws") or other similar
                  organizational instrument. The execution and delivery of this
                  Agreement and the Forward Agreement and the consummation of
                  the transactions contemplated herein and therein and the
                  fulfillment of the terms hereof will not conflict with or
                  result in a breach of any of the terms or provisions of, or
                  constitute a default under, any material contract, indenture,
                  mortgage, deed of trust or other agreement or instrument to
                  which the Company or any of the Subsidiaries is a party, or
                  the Charter or By-laws of the Company or any order, rule or
                  regulation applicable to the Company or any of the
                  Subsidiaries or any court or any regulatory body or
                  administrative agency or other governmental body having
                  jurisdiction.

         (x)      Each approval, consent, order, authorization, designation,
                  declaration or filing by or with any regulatory,
                  administrative or other governmental body necessary in
                  connection with the execution and delivery by the Company of
                  this Agreement and the Forward Agreement and the consummation
                  of the transactions herein and therein contemplated (except
                  such as may be necessary to qualify the Shares for public
                  offering by the Underwriters under state securities or Blue
                  Sky laws) has been obtained or made and is in full force and
                  effect.

         (y)      The Company and each of the Subsidiaries have all licenses,
                  certifications, permits, franchises, approvals, clearances and
                  other regulatory authorizations ("Permits") from governmental
                  authorities as are necessary to conduct their businesses as
                  currently conducted and to own, lease and operate their
                  properties in the manner described in the Prospectus, except
                  where the failure to hold such Permits would not have a
                  Material Adverse Effect. There is no claim, proceeding or
                  controversy, pending or, to the knowledge of the Company or
                  any of the Subsidiaries, threatened, involving the status of
                  or sanctions under any of the Permits. The Company and each of
                  the Subsidiaries have fulfilled and performed all of their
                  material obligations with respect to the Permits, and no event
                  has occurred that allows, or after notice or lapse of time
                  would allow, the revocation, termination, modification or
                  other impairment of the rights of the Company or any of the
                  Subsidiaries under such Permit.

         (z)      To the Company's knowledge, except for affiliations with Wayne
                  Hummer Investments, LLC, a Delaware limited liability company
                  and one of the Subsidiaries ("WHI"), and Focused Investments,
                  LLC, an Illinois limited liability

                                       10


                  company and one of the Subsidiaries ("Focused"), there are no
                  affiliations or associations between any member of the
                  National Association of Securities Dealers, Inc. (the "NASD")
                  and any of the Company's officers, directors or 5% or greater
                  security holders, except as set forth in the Registration
                  Statement or in questionnaires completed by such persons and
                  previously delivered to counsel for the Underwriters.

         (aa)     Neither the Company, nor to the Company's knowledge, any of
                  its affiliates, has taken or may take, directly or indirectly,
                  any action designed to cause or result in, or that has
                  constituted or that might reasonably be expected to
                  constitute, the stabilization or manipulation of the price of
                  the shares of Common Stock to facilitate the sale or resale of
                  the Shares. The Company acknowledges that the Underwriters may
                  engage in passive market making transactions in the Shares on
                  the Nasdaq National Market in accordance with Regulation M
                  under the Exchange Act.

         (bb)     Neither the Company nor any of the Subsidiaries is, nor will
                  be after receipt of payment for the Shares, an "investment
                  company" or an entity "controlled" by an "investment company"
                  within the meaning of such term under the Investment Company
                  Act of 1940, as amended (the "Investment Company Act"), and
                  the rules and regulations of the Commission thereunder. The
                  Company and the Subsidiaries will conduct their businesses in
                  a manner so that they will not become subject to the
                  Investment Company Act.

         (cc)     The Company and each of the Subsidiaries carry, or are covered
                  by, insurance in such amounts and covering such risks as is in
                  the reasonable judgment of the Company adequate and
                  commercially reasonable for the conduct of their respective
                  businesses and the value of their respective properties and as
                  is customary for companies engaged in similar businesses. All
                  policies of insurance insuring the Company or any Subsidiary
                  or any of their respective businesses, assets, employees,
                  officers and directors are in full force and effect, and the
                  Company and the Subsidiaries are in compliance with the terms
                  of such policies, except where the failure to be in such
                  compliance would not have a Material Adverse Effect. There are
                  no claims by the Company or any Subsidiary under any such
                  policy or instrument as to which an insurance company is
                  denying liability or defending under a reservation of rights
                  clause, except where the denial of such claims would not have
                  a Material Adverse Effect.

         (dd)     The Company is in compliance in all material respects with all
                  presently applicable provisions of the Employee Retirement
                  Income Security Act of 1974, as amended, including the
                  regulations and published interpretations thereunder
                  ("ERISA"); the Company has no "pension plan" (as defined in
                  ERISA) for which it would have any liability; the Company has
                  not incurred and does not expect to incur liability under (i)
                  Title IV of ERISA with respect to termination of, or
                  withdrawal from, any "pension plan" or (ii) Sections 412 or
                  4971 of the Internal Revenue Code of 1986, as amended,
                  including the regulations and published interpretations
                  thereunder (the "Code"); and each "pension plan" for which the

                                       11


                  Company would have any liability that is intended to be
                  qualified under Section 401(a) of the Code is so qualified in
                  all material respects and nothing has occurred, whether by
                  action or by failure to act, that would cause the loss of such
                  qualification.

         (ee)     Other than as contemplated by this Agreement, the Company has
                  not incurred any liability for any finder's or broker's fee,
                  or agent's commission, in connection with the execution and
                  delivery of this Agreement or the consummation of the
                  transactions contemplated hereby.

         (ff)     Neither the Company nor any of the Subsidiaries has sent or
                  received any notice indicating the termination of or intention
                  to terminate any of the contracts or agreements referred to or
                  described in the Registration Statement or the Prospectus, or
                  filed as an exhibit to the Registration Statement or any of
                  the documents incorporated by reference into the Registration
                  Statement or the Prospectus, the termination of which would
                  have a Material Adverse Effect, and no such termination has
                  been threatened by the Company, any Subsidiary or any other
                  party to any such contract or agreement, except as would not
                  have Material Adverse Effect.

         (gg)     Neither the Company nor any Subsidiary is in violation of any
                  statute, rule, regulation, decision or order of any
                  governmental agency or body or any court, domestic or foreign,
                  relating to the use, disposal or release of hazardous
                  chemicals, toxic substances or radioactive and biological
                  materials or relating to the protection or restoration of the
                  environment or human exposure to hazardous chemicals, toxic
                  substances or radioactive and biological materials
                  (collectively, "Environmental Laws"). Neither the Company nor
                  any of the Subsidiaries owns or operates any real property
                  contaminated with any substance that is subject to any
                  Environmental Laws, is liable for any off-site disposal or
                  contamination pursuant to any Environmental Laws or is subject
                  to any claim relating to any Environmental Laws, which
                  violation, contamination, liability or claim would
                  individually or in the aggregate have a Material Adverse
                  Effect; and the Company is not aware of any pending
                  investigation that might lead to such a claim.

         (hh)     No payments or inducements have been made or given, directly
                  or indirectly, to any Federal or local official or candidate
                  for any Federal or state office in the United States or
                  foreign offices by the Company or any Subsidiary or, to the
                  best knowledge of the Company, by any of their officers,
                  directors, employees or agents or by any other person in
                  connection with any opportunity, contract, permit,
                  certificate, consent, order, approval, waiver or other
                  authorization relating to the business of the Company or any
                  Subsidiary, except for such payments or inducements as were
                  lawful under applicable laws, rules and regulations. Neither
                  the Company nor any Subsidiary, nor, to the best knowledge of
                  the Company, any director, officer, agent, employee or other
                  person associated with or acting on behalf of the Company or
                  any Subsidiary, (i) has used any corporate funds for any
                  unlawful contribution, gift, entertainment or other unlawful
                  expense relating to political activity; (ii) made any direct
                  or indirect unlawful payment to any

                                       12


                  government official or employee from corporate funds; (iii)
                  violated or is in violation of any provision of the Foreign
                  Corrupt Practices Act of 1977; or (iv) made any bribe,
                  unlawful rebate, payoff, influence payment, kickback or other
                  unlawful payment in connection with the businesses of the
                  Company or any Subsidiary.

         (ii)     The Company and each of the Subsidiaries own or possess all
                  patents, patent applications, trademarks, service marks,
                  tradenames, trademark registrations, service mark
                  registrations, copyrights, licenses, inventions, trade secrets
                  and rights necessary for the conduct of the businesses of the
                  Company and the Subsidiaries as currently carried on and as
                  described in the Registration Statement and Prospectus except
                  where the failure to so own or possess would not have a
                  Material Adverse Effect; except as stated in the Registration
                  Statement and the Prospectus, to the best knowledge of the
                  Company, no name that the Company or any of the Subsidiaries
                  uses and no other aspect of the businesses of the Company or
                  any of the Subsidiaries will involve or give rise to any
                  infringement of, or license or similar fees for, any patents,
                  patent applications, trademarks, service marks, tradenames,
                  trademark registrations, service mark registrations,
                  copyrights, licenses, inventions, trade secrets or other
                  similar rights of others that could reasonably be expected to
                  have a Material Adverse Effect. Neither the Company nor any of
                  the Subsidiaries has received any notice alleging any such
                  infringement or fee, except as the Company does not reasonably
                  expect to have a Material Adverse Effect.

         (jj)     The Company and each of the Subsidiaries (i) are in compliance
                  with Federal, state, local and foreign laws, statutes,

                  Company nor any of the Subsidiaries has received any
                  notification asserting any failure to comply with or violation
                  of any such Laws; (ii) are not, nor are any of their
                  respective affiliates, subject to a "statutory disability" as
                  defined in Section 3(a)(39) of the Exchange Act; and (iii)
                  have filed all reports, registrations and statements, together
                  with any amendments required to be made with respect

                                       13


                  thereto, that were required to be filed (A) with the Federal
                  Reserve, HUD, the FHA, FHLMC, FNMA, FDIC, OCC, IDFPR, USDA, UA
                  and WDFI and (B) under any applicable statute, rule,
                  regulation, law or order, with any applicable governmental
                  authority or self-regulatory organization with jurisdiction
                  over any of the activities of the Company or the Subsidiaries
                  (other than filings with such other governmental authorities
                  or self-regulating organizations which individually or in the
                  aggregate are not material to the business of the Company or
                  the Subsidiaries taken as a whole) including reports relating
                  to escheatment of funds (collectively, the "Company Regulatory
                  Reports"), and have paid all fees in connection therewith,
                  except where the failure to make any such filing could not
                  reasonably be expected to be material. As of their respective
                  dates, the Company Regulatory Reports complied in all respects
                  with the applicable statutes, rules, regulations, laws and
                  orders enforced or promulgated by the governmental authority
                  or self-regulatory organization with which they were filed,
                  except in all such cases described in clauses (i) - (iii) of
                  the preceding sentence where such noncompliance or violation
                  would not have a Material Adverse Effect, and did not contain
                  any untrue statement of a material fact or omit to state a
                  material fact required to be stated therein or necessary to
                  make the statement therein, in the light of the circumstances
                  under which they were made, not misleading.

         (kk)     The activities of the Company and the Subsidiaries are
                  permitted under applicable Federal and state banking laws and
                  regulations. First Insurance Funding Corp., a Subsidiary of
                  the Company, is validly licensed by the Illinois Department of
                  Insurance and in all other jurisdictions in which the conduct
                  of its business requires license or qualification. The Company
                  has all necessary approvals, including the approval of HUD,
                  the FHA, FHLMC, FNMA, IDFPR, OCC, USDA, UA, WDFI and the
                  Federal Reserve, as applicable, to own the capital stock of
                  its subsidiaries. Neither the Company nor any of its
                  Subsidiaries, nor, to the Company's knowledge, any of their
                  respective directors, officers or trustees, is party or
                  subject to, or has received any notice or advice that any of
                  them may become party or subject to, any investigation with
                  respect to, any cease-and-desist order, agreement, memorandum
                  of understanding, commitment letter, directive or other
                  regulatory enforcement action, proceeding or order with or by,
                  or has been a recipient of any supervisory letter from, or has
                  adopted any board resolutions at the request of, any regulator
                  (including HUD, the FHA, FHLMC, FNMA, IDFPR, OCC, USDA, UA,
                  WDFI, the Federal Reserve, the FDIC, or any other federal or
                  state agency charged with the supervision or regulation of
                  depository institutions, banks, or financial holding
                  companies, or engaged in the insurance of depository
                  institution deposits, or any court, administrative agency or
                  commission or other governmental agency, authority or
                  instrumentality having supervisory or regulatory authority
                  with respect to the Company or any of its Subsidiaries (each,
                  a "Regulator")) that imposes any restrictions or requirements
                  not generally applicable to entities of the same type as the
                  Company and the Subsidiaries or currently restricts in any
                  material respect the conduct of their business or that in any
                  material manner relates to their capital adequacy, their
                  credit policies, their ability or authority to pay dividends
                  or make distributions to their shareholders or

                                       14


                  make payments of principal or interest on their debt
                  obligations, their management or their business (each a
                  "Regulatory Agreement"), nor has the Company or any of its
                  Subsidiaries been advised by any Regulator that it is
                  considering issuing or requesting any such Regulatory
                  Agreement, except for Regulatory Agreements that would not,
                  individually or in the aggregate, have a Material Adverse
                  Effect. There is no material unresolved violation, criticism
                  or exception by any Regulator with respect to any report or
                  statement relating to any examinations of the Company or any
                  of its Subsidiaries.

         (ll)     Neither the Company nor any of the Banks has received any
                  notice of non-compliance with the applicable provisions of the
                  Community Reinvestment Act ("CRA") and the regulations
                  promulgated thereunder, and each of the Banks has received a
                  CRA rating of satisfactory or better from the FDIC or other
                  applicable governmental authority. The Company knows of no
                  facts or circumstances that would cause any of the Banks to
                  fail to comply with such provisions or cause the CRA rating of
                  any such Bank to fall below satisfactory.

         (mm)     To the best knowledge of the Company, each of the Company and
                  the Subsidiaries has properly administered all accounts for
                  which any of them acts as a fiduciary, including, but not
                  limited to, accounts for which any of them serves as a
                  trustee, agent, custodian, personal representative, guardian,
                  conservator or investment adviser, in accordance with the
                  terms of the governing documents and applicable state and
                  Federal law and regulation and common law, except where the
                  failure to have so administered or to be in compliance would
                  not have a Material Adverse Effect. None of the Company, the
                  Subsidiaries or any of their respective directors, officers or
                  employees has committed any material breach of trust with

                  each such fiduciary account are true and correct in all
                  material respects and accurately reflect the assets of such
                  fiduciary account in all material respects.

         (nn)     Each agreement under which the Company and the Subsidiaries,
                  including, without limitation, Wayne Hummer Asset Management
                  Company ("WHMC"), provides investment advisory service to any
                  person that is subject to Section 15 of the Investment Company
                  Act has been duly approved at all times in compliance in all
                  material respects with Section 15 of the Investment Company
                  Act and applicable Law. Except where the failure, either
                  individually or in the aggregate, would not have a Material
                  Adverse Effect, each such investment advisory contract has
                  been performed in accordance with the Investment Company Act
                  and any other applicable Law.

         (oo)     WHMC is duly registered as an investment adviser with the

                  registration or qualification is required by virtue of the
                  activities of such person, except where such failure, either
                  individually or in the aggregate, would not have a Material
                  Adverse Effect. WHMC has made such notice filings with such
                  states as are

                                       15


                  required by state law, except where such failure would not
                  have a Material Adverse Effect. WHI and Focused are duly
                  registered as broker-dealers with the Commission under the
                  Exchange Act and with each state agency pursuant to which each
                  such entity is required to be registered by virtue of the
                  conduct of its business. Each associated person of WHI and
                  Focused is duly licensed, registered or qualified in each
                  state in which such licensing, registration or qualification
                  is required by virtue of the activities of such person, except
                  where such failure, either individually or in the aggregate,
                  would not have a Material Adverse Effect. WHI is a member in
                  good standing of the New York Stock Exchange, Inc. ("NYSE"),
                  the NASD, the Chicago Stock Exchange, Incorporated ("CHX") and
                  the American Stock Exchange, Inc. ("AMEX"). Focused is a
                  member in good standing of the NASD. Other than WHI, Focused

                  registered as, an investment adviser or a broker-dealer with
                  the Commission or any applicable state regulatory agency. Each
                  of WHMC, WHI and Focused has timely filed all forms, reports,
                  registration statements, schedules and other documents,
                  together with any amendments required to be made with respect
                  thereto, that were required to be filed with any Federal,
                  state or securities self-regulatory organization, including,
                  without limitation, the Commission, NYSE, NASD, CHX and AMEX,
                  and has paid all fees and assessments due and payable in
                  connection therewith, except where such failure to file such
                  reports, registration statements, schedules and other
                  documents or to pay such fees and assessments, either
                  individually or in the aggregate, would not have a Material
                  Adverse Effect. As of their respective dates, all forms,
                  reports, schedules or other filings made by each of WHMC, WHI
                  and Focused with Federal, state or securities self-regulatory
                  organizations or authorities complied in all material respects
                  with the applicable requirements of Federal and state
                  securities laws and the rules and regulations of such
                  securities self-regulatory organizations or authorities. None
                  of such filings, as of their respective dates, contained any
                  untrue statement of material fact, or omitted to state a
                  material fact required to be stated therein or necessary in
                  order to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading. None
                  of WHMC, WHI or Focused or any other affiliate of the Company
                  (other than the WH Funds (as defined below)) is required to be
                  registered as an investment company with the Commission under

                  Wayne Hummer CorePortfolio Fund (collectively, the "WH
                  Funds"), each of which is a portfolio of the Wayne Hummer
                  Investment Trust, which is registered as an investment company
                  with the Commission under the Investment Company Act. Except
                  as set forth in the preceding sentence, to the knowledge of
                  the Company, no person to which WHMC, WHI and Focused provide
                  investment advisory services is required to register as an
                  investment company under the Investment Company Act. Except
                  for (i) the registrations described herein and (ii) the
                  registrations of offerings by the WH Funds under the Act
                  described herein, the business activities of WHMC, WHI and
                  Focused and their respective employees (acting in their
                  capacities as such), as presently and heretofore conducted, do
                  not require any registrations

                                       16


                  under the Act, the Exchange Act or state securities law. With
                  respect to investment advisory contracts involving employee
                  benefit plans, WHMC has complied in all material respects with
                  requirements imposed on investment managers to employee
                  benefit plans under ERISA. WHMC has maintained during all
                  relevant periods fiduciary insurance.

         (pp)     The WH Funds have timely filed all forms, reports,
                  registration statements, schedules and other documents,
                  together with any amendments required to be made with respect
                  thereto, that were required to be filed with any Federal,
                  state or securities self-regulatory organization, including,
                  without limitation, the Commission, NYSE, NASD, CHX, AMEX or
                  any of their affiliates, and have paid all fees and
                  assessments due and payable in connection therewith, except
                  where such failure, either individually or in the aggregate,
                  would not have a Material Adverse Effect. WHMC has received no
                  notice from any governmental authority or securities
                  self-regulatory organization advising WHMC of the initiation
                  of any administrative proceeding or investigation into or
                  related to the business or operations of any of the WH Funds.
                  To the knowledge of the Company, there is no unresolved
                  violation, criticism or exception made in writing by any
                  governmental authority with respect to any report or statement
                  filed by the WH Funds by such governmental authority or
                  securities self-regulatory organization related to any
                  examination of the WH Funds.

2.       Representations And Warranties Of The Forward Seller.
         ----------------------------------------------------

         The Forward Seller represents and warrants to each Underwriter as of
the date hereof and as of the Closing Date (as defined in Section 3(d) hereof),
and agrees with each Underwriter, as follows:

         (a)      This Agreement has been duly authorized, executed and
                  delivered by the Forward Seller and, at the Closing Date and
                  at the Option Closing Date, the Forward Seller will have full
                  right, power and authority to sell, transfer and deliver the
                  Borrowed Shares.

         (b)      The Forward Agreement has been duly authorized, executed and
                  delivered by the Forward Seller and constitutes a valid, legal
                  and binding obligation of the Forward Seller, enforceable in
                  accordance with its terms, except as rights to indemnity
                  hereunder may be limited by Federal or state securities laws
                  and except as such enforceability may be limited by
                  bankruptcy, insolvency, reorganization or similar laws
                  affecting the rights of creditors generally, and subject to
                  general principles of equity. The Forward Seller has full
                  power and authority to enter into the Forward Agreement.

         (c)      The Forward Seller will, at the Closing Date and at the Option
                  Closing Date, have the free and unqualified right to transfer
                  the Borrowed Shares to be sold by the Forward Seller
                  hereunder, free and clear of any security interest, mortgage,
                  pledge, lien, charge, claim, equity or encumbrance of any
                  kind; and upon delivery of such Borrowed Shares and payment of
                  the purchase price as herein contemplated, assuming each of
                  the Underwriters has no notice of any adverse claim, each of
                  the Underwriters will have the free and unqualified right to
                  transfer to the Borrowed Shares purchased by it from the
                  Forward Seller, free and clear of any security interest,
                  mortgage, pledge, lien, charge, claim, equity or encumbrance
                  of any kind.

3.       Purchase, Sale And Delivery Of The Shares.
         -----------------------------------------

         (a)      On the basis of the representations, warranties and covenants
                  contained herein, and subject to the conditions set forth
                  herein, the Forward Seller agrees to sell to the several
                  Underwriters and each Underwriter agrees, severally and not
                  jointly, to purchase from the Forward Seller (including the
                  issuance and sale by the Company of Common Stock to the
                  Underwriters pursuant to Section 13(a) hereof), at the price
                  per share set forth on Schedule II hereto, the number of
                  Borrowed Shares set forth opposite the name of each
                  Underwriter in Schedule I hereof, subject to adjustments in
                  accordance with Section 10 hereof.

         (b)      If the Company does not meet all of the conditions to
                  effectiveness set forth in the Forward Agreement on or prior
                  to the Closing Date, the Forward Seller, individually, in its
                  sole judgment, may elect not to borrow and deliver for sale
                  the Borrowed Shares. In addition, in the event that, in the
                  sole judgment of the Forward Seller, it is unable to borrow
                  and deliver for sale under this Agreement

                                       18


                  all of the Borrowed Shares or if, in the Forward Seller's sole
                  judgment, it would entail a stock loan cost in excess of a
                  rate equal to 75 basis points per annum, then the Forward
                  Seller shall only be required to deliver for sale the
                  aggregate number of shares of Common Stock that such Forward
                  Seller is able to so borrow at such cost.

         (c)      If, pursuant to Section 3(b), the Forward Seller elects not to
                  borrow and deliver for sale the Borrowed Shares, the Forward
                  Seller will use its reasonable best efforts to notify the
                  Company no later than the Closing Date.

         (d)      Payment for the Borrowed Shares to be sold hereunder is to be
                  made in Federal (same day) funds to an account designated by
                  the Forward Seller against delivery of certificates therefor
                  to the Representative for the several accounts of the
                  Underwriters. Such payment and delivery are to be made through
                  the facilities of the Depository Trust Company at
                  approximately 10:00 a.m., New York time, on the third business
                  day after the date of this Agreement or at such other time and
                  date not later than five business days thereafter as you and
                  the Company shall agree upon, such time and date being herein
                  referred to as the "Closing Date." (As used herein, "business
                  day" means a day on which the NYSE is open for trading and on
                  which banks in New York are open for business and not
                  permitted by law or executive order to be closed.)

         (e)      In addition, on the basis of the representations and
                  warranties herein contained and subject to the terms and
                  conditions herein set forth, the Forward Seller hereby grants
                  an option to the several Underwriters to purchase the Option
                  Shares at the price per share as set forth in paragraph (a) of
                  this Section. The option granted hereby may be exercised in
                  whole or in part by giving written notice (i) at any time
                  before the Closing Date and (ii) only once thereafter within
                  30 days after the date of this Agreement, by you, as the
                  Representative of the several Underwriters, to the Forward
                  Seller setting forth the number of Option Shares as to which
                  the several Underwriters are exercising the option, the names
                  and denominations in which the Option Shares are to be
                  registered and the time and date at which such certificates
                  are to be delivered. The time and date at which certificates
                  for Option Shares are to be delivered shall be determined by
                  the Representative but shall not be earlier than three nor
                  later than ten full business days after the exercise of such
                  option, nor in any event prior to the Closing Date (such time
                  and date being herein referred to as the "Option Closing
                  Date"). If the date of exercise of the option is three or more
                  days before the Closing Date, the notice of exercise shall set
                  the Closing Date as the Option Closing Date. The number of
                  Option Shares to be purchased by each Underwriter shall be in
                  the same proportion to the total number of Option Shares being
                  purchased as the number of Borrowed Shares being purchased by
                  such Underwriter bears to the total number of Borrowed Shares,
                  adjusted by you, as the Representative of the several
                  Underwriters, in such manner as to avoid fractional shares.
                  The option with respect to the Option Shares granted hereunder
                  may be exercised only to cover over-allotments in the sale of
                  the Borrowed Shares by the Underwriters. You, as the
                  Representative of the several Underwriters, may cancel such
                  option at any time prior to its

                                       19


                  expiration by giving written notice of such cancellation to
                  the Forward Seller. To the extent, if any, that the option is
                  exercised, payment for the Option Shares shall be made on the
                  Option Closing Date in Federal (same day) funds drawn to the
                  order of the Company or the Forward Seller against delivery of
                  certificates therefor through the facilities of the Depository
                  Trust Company, New York, New York.

         (f)      The Forward Seller shall deliver, or cause to be delivered, a
                  credit representing the Borrowed Shares (and any shares of
                  Common Stock issued and sold by the Company to the
                  Underwriters pursuant to Section 13(a)) to an account or
                  accounts at The Depository Trust Company, as designated by the
                  Representative for the accounts of the several Underwriters at
                  the Closing Date, against the irrevocable release of a wire
                  transfer of immediately available funds for the amount of the
                  purchase price therefor. The Forward Seller shall also
                  deliver, or cause to be delivered a credit representing the
                  Option Shares that the Underwriters have agreed to purchase at
                  the Closing Date (or the Option Closing Date, as the case may
                  be), to an account or accounts at The Depository Trust Company
                  as designated by the Representative for the accounts of the
                  several Underwriters, at the Closing Date or the Option
                  Closing Date, as the case may be, against the irrevocable
                  release of a wire transfer of immediately available funds for
                  the amount of the purchase price therefor. Time shall be of
                  the essence, and delivery at the time and place specified in
                  this Agreement is a further condition to the obligations of
                  the Underwriters.

         (g)      Not later than 12:00 noon, New York time, on the second
                  business day following the date the Shares are released by the
                  Underwriters for sale to the public, the Company shall deliver
                  or cause to be delivered copies of the Prospectus in such
                  quantities and at such places as the Representatives shall
                  request.

4.       Offering By The Underwriters.
         ----------------------------

         It is understood that the several Underwriters are to make a public
offering of the Borrowed Shares as soon as the Representative deems it advisable
to do so. The Borrowed Shares are to be initially offered to the public at the
initial public offering price set forth in the Prospectus. The Representative
may from time to time thereafter change the public offering price and other
selling terms. To the extent, if at all, that any Option Shares are purchased
pursuant to Section 3 hereof, the Underwriters will offer them to the public on
the foregoing terms.

         It is further understood that you will act as the Representative for
the Underwriters in the offering and sale of the Shares in accordance with a
Master Agreement Among Underwriters entered into by you and the several other
Underwriters.

5.       Covenants Of The Company.
         ------------------------

         The Company covenants and agrees with the several Underwriters that:

                                       20


         (a)      The Company will (i) prepare and timely file with the
                  Commission under Rule 424(b) of the Rules and Regulations a
                  Prospectus in a form approved by the Representative; (ii) not
                  file any amendment to the Registration Statement or supplement
                  to the Prospectus of which the Representative shall not
                  previously have been advised and furnished with a copy or to
                  which the Representative shall have reasonably objected in
                  writing or that is not in compliance with the Rules and
                  Regulations; and (iii) file on a timely basis all reports and
                  any definitive proxy or information statements required to be
                  filed by the Company with the Commission subsequent to the
                  date of the Prospectus and prior to the termination of the
                  offering of the Shares by the Underwriters.

         (b)      The Company will not take, directly or indirectly, any action
                  designed to cause or result in, or that has constituted or
                  might reasonably be expected to constitute, the stabilization
                  or manipulation of the price of any securities of the Company.

         (c)      The Company will advise the Representative promptly (i) when
                  any post-effective amendment to the Registration Statement
                  shall have become effective; (ii) of receipt of any comments
                  from the Commission; (iii) of any request of the Commission
                  for amendment of the Registration Statement or for supplement
                  to the Prospectus or for any additional information; and (iv)
                  of the issuance by the Commission of any stop order suspending
                  the effectiveness of the Registration Statement or the use of
                  the Prospectus or of the institution of any proceedings for
                  that purpose. The Company will use its best efforts to prevent
                  the issuance of any such stop order preventing or suspending
                  the use of the Prospectus and to obtain as soon as possible
                  the lifting thereof, if issued.

         (d)      The Company will cooperate with the Representative in
                  endeavoring to qualify the Shares for sale under the
                  securities laws of such jurisdictions as the Representative
                  may reasonably have designated in writing and will make such
                  applications, file such documents and furnish such information
                  as may be reasonably required for that purpose, provided the
                  Company shall not be required to qualify as a foreign
                  corporation or to file a general consent to service of process
                  in any jurisdiction where it is not now so qualified or
                  required to file such a consent. The Company will, from time
                  to time, prepare and file such statements, reports and other
                  documents as are or may be required to continue such
                  qualifications in effect for so long a period as the
                  Representative may reasonably request for distribution of the
                  Shares.

         (e)      The Company will deliver to, or upon the order of, the
                  Representative, from time to time, as many copies of any
                  preliminary prospectus as the Representative may reasonably
                  request. The Company will deliver to, or upon the order of,
                  the Representative during the period when delivery of a
                  Prospectus is required under the Act, as many copies of the
                  Prospectus in final form, or as thereafter amended or
                  supplemented, as the Representative may reasonably request.
                  The Company will deliver to the Representative at or before
                  the Closing Date, four signed copies of the Registration
                  Statement and all amendments thereto including all exhibits
                  filed therewith, and will deliver to the Representative such
                  number of copies of

                                       21


                  the Registration Statement (including such number of copies of
                  the exhibits filed therewith that may reasonably be
                  requested), and of all amendments thereto, as the
                  Representative may reasonably request.

         (f)      The Company will comply with the Act and the Rules and
                  Regulations, and the Exchange Act and the rules and
                  regulations of the Commission thereunder, so as to permit the
                  completion of the distribution of the Shares as contemplated
                  in this Agreement and the Prospectus. If, during the period in
                  which a prospectus is required by law to be delivered by an
                  Underwriter or dealer, any event shall occur as a result of
                  which, in the judgment of the Company or in the reasonable
                  opinion of the Underwriters, it becomes necessary to amend or
                  supplement the Prospectus in order to make the statements
                  therein, in the light of the circumstances existing at the
                  time the Prospectus is delivered to a purchaser, not
                  misleading, or, if it is necessary at any time to amend or
                  supplement the Prospectus to comply with any law, the Company
                  promptly will prepare and file with the Commission an
                  appropriate amendment to the Registration Statement or
                  supplement to the Prospectus so that the Prospectus as so
                  amended or supplemented will not, in the light of the
                  circumstances when it is so delivered, be misleading, or so
                  that the Prospectus will comply with the law.

         (g)      The Company will make generally available to its security
                  holders, as soon as it is practicable to do so, but in any
                  event not later than 15 months after the effective date of the
                  Registration Statement, an earnings statement (which need not
                  be audited) in reasonable detail, covering a period of at
                  least 12 consecutive months beginning after the Effective
                  Date, which earnings statement shall satisfy the requirements
                  of Section 11(a) of the Act and Rule 158 of the Rules and
                  Regulations and will advise you in writing when such statement
                  has been so made available.

         (h)      Prior to the Closing Date, the Company will furnish to the
                  Underwriters, as soon as they have been prepared by or are
                  available to the Company, a copy of any unaudited interim
                  financial statements of the Company for any period subsequent
                  to the period covered by the most recent financial statements
                  appearing in the Registration Statement and the Prospectus.

         (i)      The Company will not offer, sell, contract to sell, pledge or
                  otherwise dispose of, directly or indirectly, or file with the
                  Commission a registration statement under the Act relating to,
                  any shares of Common Stock or securities convertible into or
                  exchangeable or exercisable for any shares of Common Stock or
                  derivative of Common Stock, or publicly disclose the intention
                  to make any such offer, sale, pledge, disposition or filing,
                  otherwise than hereunder or with the prior written consent of
                  the Representative, for a period of 90 days after the date of
                  this Agreement, except for (i) grants of employee stock
                  options or awards pursuant to the terms of a plan in effect on
                  the date of this Agreement, (ii) issuances pursuant to the
                  exercise of the Company's stock options or warrants or
                  pursuant to the Company's Employee Stock Purchase Plan, 1997
                  Stock Incentive Plan, as amended, or the Directors Deferred
                  Fee and Stock Plan, (iii) the filing of a

                                       22


                  Form S-8 registration statement relating to the registration
                  of shares of Common Stock pursuant to such plans, (iv) the
                  filing of a Form S-4 registration statement in connection with
                  the Company's acquisition of First Northwest and the First
                  Northwest Merger Agreement and the issuance of shares of
                  Common Stock in connection with such transaction and (v) the
                  filing of any post-effective amendments to any registration
                  statement currently on file, if required, provided that no
                  such post-effective amendment increases the number of shares
                  or amount of securities covered by any such registration
                  statement.

         (j)      The Company shall use its best efforts to obtain approval for
                  additional shares of Common Stock (such that all of the Shares
                  shall be quoted on or approved for quotation on the Nasdaq
                  National Market or in lieu thereof the NYSE or another
                  national securities exchange), including the filing of a
                  Nasdaq Notification Form of Change in the Number of Shares
                  Outstanding with The Nasdaq Stock Market, Inc. within the
                  prescribed time period, and, provided the Common Stock
                  continues to be publicly held, to remain so listed for at
                  least five years from the Effective Date or for such shorter
                  period as may be specified in a written consent of the
                  Representative.

         (k)      The Company has caused each executive officer and director of
                  the Company to furnish to you, on or prior to the date of this
                  Agreement, a letter or letters, in form and substance
                  satisfactory to the Representative, pursuant to which each
                  such person shall agree not to offer, sell, sell short or
                  otherwise dispose of any shares of Common Stock or other
                  capital stock of the Company, or any other securities
                  convertible, exchangeable or exercisable for shares of Common

                  person or request the registration for the offer or sale of
                  any of the foregoing (as to which such person has the right to
                  direct for the disposition of) for a period of 90 days after
                  the date of this Agreement, directly or indirectly, except
                  with the prior written consent of RBC Capital Markets
                  Corporation ("Lockup Agreements").

         (l)      The Company shall apply the net proceeds of the sale of the
                  Shares as described under the heading "Use of Proceeds" in the
                  Prospectus.

         (m)      The Company shall not invest, or otherwise use the proceeds
                  received by the Company from the sale of the Shares, in such a
                  manner as would require the Company or any of the Subsidiaries
                  to register as an investment company under the Investment
                  Company Act.

         (n)      Provided the Company continues to be publicly held, the
                  Company will maintain a transfer agent and, if necessary under
                  the jurisdiction of incorporation of the Company, a registrar
                  for the Common Stock.

                  the Company shall not, for a period of 180 days after the date
                  hereof, without the prior written consent of the
                  Representative, purchase, redeem or call for redemption, or
                  prepay or give notice of prepayment (or announce any
                  redemption or call for redemption, or any repayment or notice
                  of prepayment) of any of the Company's securities.

         (p)      Prior to the Closing Date (and, if applicable, the Option
                  Closing Date), the Company will not issue any press release or
                  other communication directly or indirectly or hold any press
                  conference with respect to the Company, any of the
                  Subsidiaries or the offering of the Shares without your prior
                  written consent.

         (q)      The Company and the Subsidiaries shall use their best efforts
                  to conduct their businesses in material compliance with all
                  applicable Federal and state laws, rules, regulations,

                  limitation, the applicable provisions of the Act, the Rules
                  and Regulations, the Exchange Act, the Exchange Act Rules and
                  Regulations, the Sarbanes-Oxley Act, the Investment Company

                  applicable).

6.       Costs and Expenses.
         ------------------

         The Company will pay all costs, expenses and fees incident to the
performance of the obligations of the Company under this Agreement and the
Forward Agreement, including, without limiting the generality of the foregoing,

         The Company shall not, however, be required to pay for any of the
Underwriters' expenses (other than those related to qualification under NASD
regulation and state securities or Blue Sky laws) except that, if this Agreement
shall not be consummated because the conditions in Section 7 hereof are not
satisfied, or because this Agreement is terminated by the Representative
pursuant to Section 12 hereof, or by reason of any failure, refusal or inability
on the part of the Company to perform any undertaking or satisfy any condition
of this Agreement or to comply with any of the terms hereof on its part to be
performed, unless such failure to satisfy said condition or to comply with said
terms shall be due to the default or omission of any

                                       24


Underwriter, then the Company shall reimburse the several Underwriters for
reasonable out-of-pocket expenses, including all fees and disbursements of
counsel, reasonably incurred in connection with investigating, marketing and
proposing to market the Shares or in contemplation of performing their
obligations hereunder; but the Company shall not in any event be liable to any

profits from the sale by them of the Shares.

7.       Conditions Of Obligations Of The Underwriters.
         ---------------------------------------------

         The several obligations of the Underwriters to purchase the Borrowed

                  thereto shall have become effective and any and all filings
                  required by Rule 424 and Rule 430A of the Rules and

                  shall have been issued and no proceedings for that purpose
                  shall have been taken or, to the knowledge of the Company,
                  shall be contemplated by the Commission and no injunction,
                  restraining order or order of any nature by a Federal or state
                  court of competent jurisdiction shall have been issued as of
                  the Closing Date that would prevent the issuance of the
                  Shares.

         (b)      The Representative shall have received on the Closing Date and
                  the Option Closing Date, if any, the opinion of Vedder, Price,
                  Kaufman & Kammholz, P.C., counsel for the Company, each dated
                  the Closing Date or the Option Closing Date, if any, addressed
                  to the Underwriters to the effect that:

                  (i)      The Company is validly existing as a corporation in
                           good standing under the laws of the State of
                           Illinois, and is duly registered as a financial
                           holding company under the BHC Act. Each of the
                           Subsidiaries is validly existing in good standing
                           under the laws of its jurisdiction of incorporation
                           or organization (as the case may be). Each of the
                           Company and the Subsidiaries has full corporate
                           power, or power under its organizational documents,
                           and authority to own or lease its properties and to
                           conduct its business as currently being carried on in
                           all material respects and as described in the
                           Registration Statement and Prospectus. Each of the
                           Subsidiaries listed on Exhibit A to such opinion is
                           duly qualified to do business as a foreign entity and
                           is in good standing in the jurisdictions listed on
                           such Exhibit A.

                                       25


                  (ii)     The capital stock of the Company conforms as to legal
                           matters to the description thereof contained in or
                           incorporated by reference into the Prospectus. All of
                           the issued and outstanding shares of capital stock of
                           the Company have been duly authorized and validly
                           issued and are fully paid and nonassessable. The
                           Borrowed Shares and Option Shares to be purchased by
                           the Forward Seller in accordance with the settlement
                           provisions of the Forward Agreement have been duly
                           authorized and, when issued, delivered and paid for
                           in accordance with the terms of the Forward
                           Agreement, will have been validly issued and will be
                           fully paid and nonassessable, and the holders thereof
                           will not be subject to personal liability by reason
                           of being such holders. Except as otherwise stated in
                           the Registration Statement and Prospectus, there are
                           no preemptive rights or other rights to subscribe for
                           or to purchase, or any restriction upon the voting or
                           transfer of, any shares of Common Stock pursuant to
                           the Company's Charter, By-laws or, to such counsel's
                           knowledge, any agreement or other instrument to which
                           the Company is a party or by which the Company is
                           bound. To such counsel's knowledge, neither the
                           filing of the Registration Statement nor the offering
                           or sale of the Shares as contemplated by this
                           Agreement gives rise to any rights for or relating to
                           the registration of any shares of Common Stock or
                           other securities of the Company.

                  (iii)    To such counsel's knowledge, all outstanding shares
                           of capital stock of or other equity interests in the
                           Subsidiaries have been duly and validly authorized
                           and issued and are fully paid and nonassessable
                           (except to the extent such shares or interests may be
                           deemed assessable under 12 U.S.C. Section 55 or 12
                           U.S.C. 1831o) and, to such counsel's knowledge,
                           except as otherwise described in the Registration
                           Statement and the Prospectus and except for
                           directors' qualifying shares, the Company owns of
                           record and beneficially, free and clear of any
                           security interests, liens or other encumbrances, all
                           of the issued and outstanding shares of such stock or
                           interests. To such counsel's knowledge, except as
                           outstanding under the Company's 1997 Stock Incentive
                           Plan, as amended, its Employee Stock Purchase Plan or
                           its Director Deferred Fee and Stock Plan or otherwise
                           described in the Registration Statement and the
                           Prospectus, there are no options, warrants or other
                           rights in existence to purchase or acquire from the
                           Company or any Subsidiary any shares of the capital
                           stock of or other equity interests in the Company or
                           any of the Subsidiaries.

                  (iv)     The Registration Statement has become effective under
                           the Act and, to such counsel's knowledge, no stop
                           order suspending the effectiveness of the
                           Registration Statement has been issued and no
                           proceeding for that purpose has been instituted or,
                           to the knowledge of such counsel, threatened by the
                           Commission.

                  (v)      The descriptions in the Registration Statement and
                           the Prospectus of statutes, regulations and legal and
                           governmental proceedings under the

                                       26


                           captions "Price Range of Common Stock and Dividend
                           Policy--Common Stock Dividend Policy" in the
                           Prospectus and "Business--Supervision and
                           Regulation," " -- Bank Holding Company Regulation,"

                           Investment Adviser Regulation" in the Company's
                           Annual Report on Form 10-K for the year ended
                           December 31, 2003, insofar as such descriptions
                           constitute a summary of legal and regulatory matters
                           are accurate in all material respects and fairly
                           present the information required to be shown; and
                           such counsel does not know of any statutes,
                           regulations or legal or governmental proceedings
                           required to be described in the Prospectus that are
                           not described as required. Furthermore, the
                           information in the Prospectus concerning the Forward
                           Agreement under the caption "Underwriting"
                           constitutes a fair summary of the Forward Agreement
                           in all material respects.

                  (vi)     The Company has full corporate power and authority to
                           enter into this Agreement and the Forward Agreement,
                           and this Agreement and the Forward Agreement have
                           been duly authorized, executed and delivered by the
                           Company; the execution, delivery and performance of
                           this Agreement and the Forward Agreement and the
                           consummation of the transactions herein and therein
                           contemplated will not result in (A) a breach or
                           violation of any of the terms and provisions of, or
                           constitute a default under, the Company's Charter or
                           By-laws or (B) a material breach or violation of any
                           term and provisions of, or constitute a material
                           default under, any statute, rule or regulation, any
                           agreement or instrument known to such counsel to
                           which the Company is a party or by which it is bound
                           or to which any of its property is subject, or any
                           order or decree known to such counsel of any court or
                           governmental agency or body having jurisdiction over
                           the Company or any Subsidiary or any of their
                           respective properties; and no consent, approval,
                           authorization or order of, or filing with, any court
                           or governmental agency or body is required for the
                           execution, delivery and performance of this Agreement
                           and the Forward Agreement or for the consummation of
                           the transactions contemplated hereby and thereby,
                           including the issuance or sale of the Shares by the
                           Company, except such as may be required under the Act
                           or state securities laws or Blue Sky laws or
                           interpretations or rules of the NASD in connection
                           with the purchase and distribution of the Shares by
                           the Underwriters.

                  (vii)    The issuance and sale by the Company of Settlement
                           Shares (as defined in the Forward Agreement) to the
                           Forward Purchaser in settlement of the Forward
                           Agreement in accordance with the terms thereof will
                           not require registration under the Act, and the
                           Forward Seller will not have an obligation to deliver
                           a Prospectus in connection with the Settlement Shares
                           delivered to it by the Company upon such settlement,
                           assuming that (i) Prospectuses were delivered by the
                           Underwriters in connection with sales of Borrowed
                           Shares in an amount not less than the Base Amount (as
                           defined in the Forward Agreement) and (ii) the
                           Forward Purchaser only

                                       27


                           delivers the Settlement Shares to close out open
                           borrowings created in the course of the hedging
                           activities created by the Forward Purchaser relating
                           to its exposure under the Forward Agreement in
                           compliance with the Forward Agreement.

                  (viii)   The Registration Statement and the Prospectus
                           (including any documents incorporated by reference
                           into the Prospectus, at the time they were filed)
                           comply or complied in all material respects as to
                           form with the applicable requirements of the Act and
                           the Rules and Regulations, and the Exchange Act and
                           the rules and regulations of the Commission
                           thereunder (except that such counsel need not express
                           an opinion as to financial statements and related
                           schedules or financial data contained in the
                           Registration Statement or the Prospectus or
                           incorporated by reference therein). The conditions
                           for the use of Form S-3, set forth in the General
                           Instructions thereto, have been satisfied.

                  (ix)     Such counsel does not know of any contracts or
                           documents required to be filed as exhibits to the
                           Registration Statement or described in the
                           Registration Statement or the Prospectus that are not
                           so filed or described as required, and such documents
                           as are summarized in the Registration Statement or
                           the Prospectus are fairly summarized in all material
                           respects.

                  (x)      Such counsel knows of no material legal or
                           governmental proceedings pending or threatened
                           against the Company or any of the Subsidiaries except
                           as set forth in the Prospectus.

                  (xi)     The Company is not, and will not become, as a result
                           of the consummation of the transactions contemplated
                           by this Agreement and the Forward Agreement, and
                           application of the net proceeds therefrom as
                           described in the Prospectus, required to register as
                           an investment company under the Investment Company
                           Act.

         In rendering such opinion, Vedder, Price, Kaufman & Kammholz, P.C. (x)
may rely as to matters of fact to the extent such counsel deems appropriate upon
appropriate certificates of officers of the Company and the Subsidiaries and (y)
shall opine as to matters governed by the laws of the states of Illinois,
Delaware and New York and Federal laws. In addition to the matters set forth
above, such opinion shall also include a statement to the effect that nothing
has come to the attention of such counsel that leads them to believe that (i)
the Registration Statement, at the time it became effective under the Act and as
of the Closing Date or the Option Closing Date, if any, contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
(ii) the Prospectus, or any supplement thereto, on the date it was filed
pursuant to the Rules and Regulations and as of the Closing Date or the Option
Closing Date, if any, contained an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they are made, not
misleading (except that such counsel need express no view as to financial
statements and related schedules therein). With respect to such statement,
Vedder, Price, Kaufman &

                                       28


Kammholz, P.C. may state that their belief is based upon the procedures set
forth therein, but is without independent check and verification.

         (c)      The Representative shall have received from Reinhart Boerner
                  Van Deuren s.c., Wisconsin counsel for the Company, an opinion
                  dated the Closing Date and the Option Closing Date, if any,
                  with respect to such matters as the Representative may
                  reasonably request.

         (d)      The Representative shall have received from Jones Day, counsel
                  for the Underwriters, an opinion dated the Closing Date and
                  the Option Closing Date, if any, with respect to the validity
                  of the Shares, certain matters relating to the Forward
                  Agreement and other related matters as the Representative
                  reasonably may request, and such counsel shall have received
                  such papers and information as they request to enable them to
                  pass upon such matters.

         (e)      The Representative shall have received at or prior to the
                  Closing Date from Jones Day a memorandum or summary, in form
                  and substance satisfactory to the Representative, with respect
                  to the qualification for offering and sale by the Underwriters
                  of the Shares under the state securities or Blue Sky laws of
                  such jurisdictions as the Representative may reasonably have
                  designated to the Company.

         (f)      The Representative shall have received, on each of the dates
                  hereof, the Closing Date and the Option Closing Date, if any,
                  a letter dated the date hereof, the Closing Date or the Option
                  Closing Date, if any, in form and substance reasonably
                  satisfactory to the Representative, of Ernst & Young LLP
                  confirming that they are independent public accountants within
                  the meaning of the Act and the applicable published Rules and
                  Regulations thereunder and stating that in their opinion the
                  financial statements and schedules examined by them and
                  included in the Registration Statement comply as to form in
                  all material respects with the applicable accounting
                  requirements of the Act and the related published Rules and
                  Regulations; and containing such other statements and
                  information as is ordinarily included in accountants' "comfort
                  letters" to Underwriters with respect to the financial
                  statements and certain financial and statistical information
                  contained in the Registration Statement and the Prospectus.

         (g)      The Representative shall have received on the Closing Date and
                  the Option Closing Date, if any, a certificate or certificates
                  of the Company's Chief Executive Officer and Chief Financial
                  Officer to the effect that, as of the Closing Date or the
                  Option Closing Date, if any, each of them severally represents
                  as follows:

                  (i)      The Registration Statement has become effective under
                           the Act and no stop order suspending the
                           effectiveness of the Registrations Statement has been
                           issued, and no proceedings for such purpose have been
                           taken or are, to his knowledge, contemplated by the
                           Commission;

                                       29


                  (ii)     The representations and warranties of the Company
                           contained in Section 1 hereof are true and correct as
                           of the Closing Date or the Option Closing Date, if
                           any;

                  (iii)    All filings required to have been made pursuant to
                           Rules 424 or 430A under the Act have been made;

                  (iv)     They have carefully examined the Registration
                           Statement and the Prospectus and, in their opinion,
                           as of the effective date of the Registration
                           Statement, the statements contained in the
                           Registration Statement were true and correct, and
                           such Registration Statement and Prospectus did not
                           omit to state a material fact required to be stated
                           therein or necessary in order to make the statements
                           therein not misleading, and since the effective date
                           of the Registration Statement, no event has occurred
                           that should have been set forth in a supplement to or
                           an amendment of the Prospectus that has not been so
                           set forth in such supplement or amendment; and

                  (v)      Since the respective dates as of which information is
                           given in the Registration Statement and the
                           Prospectus, there has not been any material adverse
                           change or any development involving a prospective
                           change, which has had or is reasonably likely to have
                           a Material Adverse Effect, whether or not arising in
                           the ordinary course of business.

         (h)      The Company shall have furnished to the Representative such
                  further certificates and documents confirming the
                  representations and warranties, covenants and conditions
                  contained herein and related matters as the Representative may
                  reasonably have requested.

         (i)      The Borrowed Shares and Option Shares, if any, have been
                  approved for quotation on the Nasdaq National Market.

         (j)      The Lockup Agreements described in Section 5(k) have been
                  furnished to the Representative.

         If any of the conditions hereinabove provided for in this Section shall
not have been fulfilled when and as required by this Agreement to be fulfilled,
the obligations of the Underwriters hereunder may be terminated by the
Representative by notifying the Company of such termination in writing on or
prior to the Closing Date or the Option Closing Date, if any.

         In such event, the Company and the Underwriters shall not be under any
obligation to each other (except to the extent provided in Sections 6, 12 and 16
hereof).

8.       Conditions of the Obligations of the Company.
         --------------------------------------------

                  The obligations of the Company to sell and deliver the Shares
required to be delivered as and when specified in this Agreement are subject to
the conditions that at the Closing Date or the Option Closing Date, if any, no
stop order suspending the effectiveness of

                                       30


the Registration Statement shall have been issued and in effect or proceedings
therefor initiated or threatened.

9.       Indemnification.
         ---------------

         (a)      The Company agrees:

                  (i)      to indemnify and hold harmless each Underwriter and
                           the Forward Seller and each person, if any, who
                           controls any Underwriter or the Forward Seller within
                           the meaning of the Act, including any general or
                           limited partner of such Underwriter or the Forward
                           Seller, against any losses, claims, damages or
                           liabilities to which such Underwriter or the Forward
                           Seller or any such controlling person may become
                           subject under the Act or otherwise, insofar as such
                           losses, claims, damages or liabilities (or actions or
                           proceedings in respect thereof) arise out of or are
                           based upon (i) any untrue statement or alleged untrue
                           statement of any material fact contained in the
                           Registration Statement, any preliminary prospectus,
                           the Prospectus or any amendment or supplement
                           thereto, (ii) the omission or alleged omission to
                           state therein a material fact required to be stated
                           therein or necessary to make the statements therein
                           not misleading any act or failure to act or (iii) any
                           alleged act or failure to act by any Underwriter in
                           connection with, or relating in any manner to, the
                           Shares or the offering contemplated hereby, and that
                           is included as part of or referred to in any loss,
                           claim, damage, liability or action arising out of or
                           based upon matters covered by clause (i) or (ii)
                           above (provided, however, that the Company shall not
                           be liable under this clause (iii) to the extent that
                           it is determined in a final judgment by a court of
                           competent jurisdiction that such loss, claim, damage,
                           liability or action resulted directly from any such
                           acts or failures to act undertaken or omitted to be
                           taken by such Underwriter or the Forward Seller
                           through its gross negligence or willful misconduct);
                           provided, however, that the Company will not be
                           liable in any such case to the extent that any such
                           loss, claim, damage or liability arises out of or is
                           based upon an untrue statement or alleged untrue
                           statement, or omission or alleged omission made in
                           the Registration Statement, any preliminary
                           prospectus, the Prospectus, or such amendment or
                           supplement, in reliance upon and in conformity with
                           written information furnished to the Company by or
                           through the Representative specifically for use in
                           the preparation thereof; and provided, further, that
                           with respect to any preliminary prospectus, the
                           foregoing indemnity agreement shall not inure to the
                           benefit of any Underwriter from whom the person
                           asserting any loss, claim, damage or liability
                           purchased Shares, or any person controlling such
                           Underwriter, if copies of the Prospectus were timely
                           delivered to the Representative pursuant to Section 5
                           and a copy of the Prospectus (as then amended or
                           supplemented if the Company shall have furnished any
                           amendments or supplements thereto) was not sent or
                           given by or on behalf of such Underwriter to such
                           person, if required by law so to have been delivered
                           and if the Prospectus (as so amended or

                                       31


                           supplemented) would have cured the defect giving rise
                           to such loss, claim, damage or liability; and

                  (ii)     to reimburse each Underwriter or the Forward Seller
                           and each such controlling person upon demand for any
                           legal or other out-of-pocket expenses reasonably
                           incurred by such Underwriter or the Forward Seller or
                           such controlling person in connection with
                           investigating or defending any such loss, claim,
                           damage or liability, action or proceeding or in
                           responding to a subpoena or governmental inquiry
                           related to the offering of the Shares, whether or not
                           such Underwriter or controlling person is a party to
                           any action or proceeding. In the event that it is
                           finally judicially determined that the Underwriters
                           or the Forward Seller were not entitled to receive
                           payments for legal and other expenses pursuant to
                           this subparagraph, the Underwriters or the Forward
                           Seller will promptly return all sums that had been
                           advanced pursuant hereto.

         (b)      Each Underwriter severally and not jointly will indemnify and
                  hold harmless the Company, each of its directors, each of its
                  officers who have signed the Registration Statement and each
                  person, if any, who controls the Company within the meaning of
                  the Act, and the Forward Seller, each of its officers,
                  directors, employees, agents and representatives and each
                  person, if any, who controls a Forward Seller within the
                  meaning of the Act, against any losses, claims, damages or
                  liabilities to which the Company or any such director, officer
                  or controlling person may become subject under the Act or
                  otherwise, insofar as such losses, claims, damages or
                  liabilities (or actions or proceedings in respect thereof)
                  arise out of or are based upon (i) any untrue statement or
                  alleged untrue statement of any material fact contained in the
                  Registration Statement, any preliminary prospectus, the
                  Prospectus or any amendment or supplement thereto or (ii) the
                  omission or the alleged omission to state therein a material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading in the light of the
                  circumstances under which they were made; and will reimburse
                  any legal or other expenses reasonably incurred by the Company
                  or any such director, officer or controlling person in
                  connection with investigating or defending any such loss,
                  claim, damage, liability, action or proceeding; provided,
                  however, that each Underwriter will be liable in each case to
                  the extent, but only to the extent, that such untrue statement
                  or alleged untrue statement or omission or alleged omission
                  has been made in the Registration Statement, any preliminary
                  prospectus, the Prospectus or such amendment or supplement, in
                  reliance upon and in conformity with written information
                  furnished to the Company by or through the Representative
                  specifically for use in the preparation thereof.

         (c)      In case any proceeding (including any governmental
                  investigation) shall be instituted involving any person in
                  respect of which indemnity may be sought pursuant to this
                  Section, such person (the "indemnified party") shall promptly
                  notify the person against whom such indemnity may be sought
                  (the "indemnifying party") in writing. No indemnification
                  provided for in Section 9(a) or (b) shall be available to any
                  party who shall fail to give notice as provided in this
                  Subsection

                                       32


                  if the party to whom notice was not given was unaware of the
                  proceeding to which such notice would have related and was
                  materially prejudiced by the failure to give such notice, but
                  the failure to give such notice shall not relieve the
                  indemnifying party or parties from any liability which it or
                  they may have to the indemnified party for contribution or
                  otherwise than on account of the provisions of Section 9(a) or
                  (b). In case any such proceeding shall be brought against any
                  indemnified party and it shall notify the indemnifying party
                  of the commencement thereof, the indemnifying party shall be
                  entitled to participate therein and, to the extent that it
                  shall wish, jointly with any other indemnifying party
                  similarly notified, to assume the defense thereof, with
                  counsel satisfactory to such indemnified party and shall pay
                  as incurred the fees and disbursements of such counsel related
                  to such proceeding. In any such proceeding, any indemnified
                  party shall have the right to retain its own counsel at its
                  own expense. Notwithstanding the foregoing, the indemnifying
                  party shall pay as incurred (or within 30 days of
                  presentation) the fees and expenses of the counsel retained by
                  the indemnified party in the event (i) the indemnifying party
                  and the indemnified party shall have mutually agreed to the
                  retention of such counsel, (ii) the named parties to any such
                  proceeding (including any impleaded parties) include both the
                  indemnifying party and the indemnified party and
                  representation of both parties by the same counsel would be
                  inappropriate due to actual or potential differing interests
                  between them or (iii) the indemnifying party shall have failed
                  to assume the defense and employ counsel acceptable to the
                  indemnified party within a reasonable period of time after
                  notice of commencement of the action.

         It is understood that the indemnifying party shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees and expenses of more than one separate firm for all such
indemnified parties. Such firm shall be designated in writing by you in the case
of parties indemnified pursuant to Section 9(a) and by the Company in the case
of parties indemnified pursuant to Section 9(b). The indemnifying party shall
not be liable for any settlement of any proceeding effected without its written
consent but if settled with such consent or if there be a final judgment for the
plaintiff, the indemnifying party agrees to indemnify the indemnified party from
and against any loss or liability by reason of such settlement or judgment. In
addition, the indemnifying party will not, without the prior written consent of
the indemnified party, settle or compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding of which
indemnification may be sought hereunder (whether or not any indemnified party is
an actual or potential party to such claim, action or proceeding) unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action or
proceeding.

         (d)      If the indemnification provided for in this Section is
                  unavailable to or insufficient to hold harmless an indemnified
                  party under Section 9(a) or (b) above in respect of any
                  losses, claims, damages or liabilities (or actions or
                  proceedings in respect thereof) referred to therein, then each
                  indemnifying party shall contribute to the amount paid or
                  payable by such indemnified party as a result of such losses,
                  claims, damages or liabilities (or actions or proceedings in
                  respect thereof) in such proportion as is appropriate to
                  reflect the relative benefits received by the

                                       33


                  Company on the one hand and the Underwriters on the other from
                  the offering of the Shares. If, however, the allocation
                  provided by the immediately preceding sentence is not
                  permitted by applicable law then each indemnifying party shall
                  contribute to such amount paid or payable by such indemnified
                  party in such proportion as is appropriate to reflect not only
                  such relative benefits but also the relative fault of the
                  Company on the one hand and the Underwriters on the other in
                  connection with the statements or omissions which resulted in
                  such losses, claims, damages or liabilities (or actions or
                  proceedings in respect thereof), as well as any other relevant
                  equitable considerations. The relative benefits received by
                  the Company on the one hand (which benefits shall include the
                  proceeds to be received by the Company pursuant to the Forward
                  Agreement), the Forward Seller and the Underwriters on the
                  other shall be deemed to be in the same proportion as the
                  total net proceeds from the offering (before deducting
                  expenses) received by the Company (which proceeds shall
                  include the proceeds to be received by the Company pursuant to
                  the Forward Agreement) bear to the total underwriting
                  discounts and commissions received by the Underwriters, in
                  each case as set forth in the table on the cover page of the
                  Prospectus. The relative fault of the Company, the Forward
                  Seller and the Underwriters shall be determined by reference
                  to, among other things, whether the untrue or alleged untrue
                  statement of a material fact or the omission or alleged
                  omission to state a material fact relates to information
                  supplied by the Company on the one hand, the Forward Seller
                  and the Underwriters on the other and the parties' relative
                  intent, knowledge, access to information and opportunity to
                  correct or prevent such statement or omission.

         The Company, the Forward Seller and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this Subsection
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to above in this
Subsection. The amount paid or payable by an indemnified party as a result of
the losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) referred to above in this Subsection shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Subsection, (i) no Underwriter shall be
required to contribute any amount in excess of the underwriting discounts and
commissions applicable to the Shares purchased by such Underwriter and (ii) no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this Subsection to contribute are several in proportion to their respective
underwriting obligations and not joint.

         (e)      Any losses, claims, damages, liabilities or expenses for which
                  an indemnified party is entitled to indemnification or
                  contribution under this Section shall be paid by the
                  indemnifying party to the indemnified party as such losses,
                  claims, damages, liabilities or expenses are incurred. The
                  indemnity and contribution agreements contained in this
                  Section and the representations and warranties of the Company
                  set forth in this Agreement shall remain operative and in full
                  force and

                                       34


                  effect, regardless of (i) any investigation made by or on
                  behalf of any Underwriter, its partners or any person
                  controlling such Underwriter, the Company, its directors or
                  officers or any person controlling the Company, (ii)
                  acceptance of any Shares and payment therefor hereunder and
                  (iii) any termination of this Agreement. A successor to any
                  Underwriter, its partners or any person controlling such
                  Underwriter or to the Company, its directors or officers or
                  any person controlling the Company, shall be entitled to the
                  benefits of the indemnity, contribution and reimbursement
                  agreements contained in this Section.

10.      Default by Underwriters.
         -----------------------

         If on the Closing Date or the Option Closing Date, if any, any
Underwriter shall fail to purchase and pay for the portion of the Shares that
such Underwriter has agreed to purchase and pay for on such date (otherwise than
by reason of any default on the part of the Company), you, as the Representative
of the Underwriters, shall use your reasonable efforts to procure within 36
hours thereafter one or more of the other Underwriters, or any others, to
purchase from the Company such amounts as may be agreed upon and upon the terms
set forth herein, the Borrowed Shares or Option Shares, as the case may be, that
the defaulting Underwriter or Underwriters failed to purchase. If during such 36
hours you, as such Representative, shall not have procured such other
Underwriters, or any others, to purchase the Borrowed Shares or Option Shares,
as the case may be, agreed to be purchased by the defaulting Underwriter or
Underwriters, then (a) if the aggregate number of shares with respect to which
such default shall occur does not exceed 10% of the Borrowed Shares or Option
Shares, as the case may be, covered hereby, the other Underwriters shall be
obligated, severally, in proportion to the respective numbers of Borrowed Shares
or Option Shares, as the case may be, that they are obligated to purchase
hereunder, to purchase the Borrowed Shares or Option Shares, as the case may be,
that such defaulting Underwriter or Underwriters failed to purchase or (b) if
the aggregate number of shares of Borrowed Shares or Option Shares, as the case
may be, with respect to which such default shall occur exceeds 10% of the
Borrowed Shares or Option Shares, as the case may be, covered hereby, the
Company or you as the Representative of the Underwriters will have the right to
terminate this Agreement without liability on the part of the non-defaulting
Underwriters or of the Company except to the extent provided in Section 9
hereof. In the event of a default by any Underwriter or Underwriters, as set
forth in this Section, the Closing Date or Option Closing Date, if any, may be
postponed for such period, not exceeding seven days, as you, as Representative,
may determine in order that the required changes in the Registration Statement
or in the Prospectus or in any other documents or arrangements may be effected.
The term "Underwriter" includes any person substituted for a defaulting
Underwriter. Any action taken under this Section shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

                  since the respective dates as of which information is given in
                  the Registration Statement and the Prospectus, any material
                  adverse change or any development involving a prospective
                  change, which (A) in the absolute discretion of any group of
                  Underwriters (which may include RBC Capital Markets
                  Corporation) that has agreed to purchase in the aggregate at
                  least 50% of the Borrowed Shares, as long as RBC Capital
                  Markets Corporation does not affirmatively assert that
                  termination should not occur, or (B) in the absolute

                  agency in respect of its monetary or fiscal affairs that in
                  your reasonable opinion has a material adverse effect on the
                  securities markets in the United States or (viii) if the
                  Forward Seller, pursuant to Section 3(b) and (e) hereof, does
                  not deliver Borrowed Shares for sale, and the Company fails to
                  deliver, pursuant to Section 13 hereof, a number of shares of
                  Common Stock equal to the number of shares that such Forward
                  Seller does not deliver; or

         (b)      as provided in Sections 7 and 10 of this Agreement.

13.      Issuance And Sale By Company.
         ----------------------------

         (a)      In the event that (i) the Company does not meet all of the
                  conditions to effectiveness set forth in the Forward Agreement
                  on or prior to the Closing Date and the Forward Seller elects,
                  pursuant to Section 3(b), not to deliver Borrowed Shares or
                  (ii) in the sole judgment of the Forward Seller, it is unable
                  to borrow and deliver for sale under this Agreement all of the
                  Borrowed Shares set forth in Schedule B opposite its name or
                  if, in the Forward Seller's sole judgment it would entail a
                  stock loan cost in excess of 75 basis points per annum, the
                  Company shall issue and sell in whole but not in part a number
                  of shares of Common Stock equal to the number of shares that
                  the Forward Seller does not deliver. The Representative shall
                  have the right to postpone the Closing Date for a period not
                  exceeding one business day in order to effect any required
                  changes in any documents or arrangements.

         (b)      The Forward Seller shall have no liability whatsoever for any
                  Borrowed Shares it does not deliver to the Company, the
                  Underwriters or any other party if the Forward Seller (i)
                  elects, pursuant to Section 3(b) not to deliver Borrowed
                  Shares because the Company has failed to meet all of the
                  conditions to effectiveness set forth in the Forward Agreement
                  or (ii) is unable to borrow and deliver for sale under this
                  Agreement all of the Borrowed Shares it is required to deliver
                  hereunder or if, in such Forward Seller's sole judgment it
                  would entail a stock loan cost in excess of a rate equal to 75
                  basis points per annum.

14.      Successors.
         ----------

Company and the Underwriters and their respective successors, executors,
administrators, heirs and assigns, and the officers, directors and controlling

obligation hereunder. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign merely because of such purchase.
