                                                  Administration

                  3.1      The Committee.  The Plan shall be administered and
interpreted by the Committee.

                  3.2      Grant of Stock Options.  The Committee shall have the
authority:

                           (a)      to grant Stock Options pursuant to the terms
of the Plan in conversion of a BHC Option pursuant to the Merger Agreement, and

                           (b)      to determine whether and under what
circumstances  a Stock Option may be settled in cash and/or stock under  Section
6.4(k).

                  3.3 Guidelines.  Subject to Article VII hereof,  the Committee
shall have the authority to adopt, alter and repeal such  administrative  rules,
guidelines  and practices  governing  this Plan as it shall,  from time to time,
deem advisable; to interpret the terms and provisions of this Plan and any Stock
Option granted under this Plan (and any  agreements  relating  thereto);  and to
otherwise  supervise the  administration of this Plan. The Committee may correct
any defect,  supply any omission or reconcile any  inconsistency in this Plan or
in any Stock  Option  granted  in the  manner  and to the  extent it shall  deem
necessary to carry out the purpose of this Plan.

                  3.4 Decisions  Final.  Any decision,  interpretation  or other
action  made or  taken  in good  faith  by the  Committee  arising  out of or in
connection  with the Plan or any Stock Option  granted  under this Plan (and any

                                                    ARTICLE IV

                                                 Share Limitation

                  4.1 Shares.  The maximum  aggregate number of shares of Common
Stock for which  Stock  Options  may be  granted  under the Plan is 46,347,
subject to any increase or decrease  pursuant to Section 4.2. The shares  issued
under the Plan may be either  authorized  and  unissued  Common  Stock or issued
Common Stock reacquired by the Company.

                  4.2  Changes.  In the  event  of any  merger,  reorganization,
consolidation,   recapitalization,  dividend  (other  than  a  dividend  or  its
equivalent  which is credited to a Plan Participant or a regular cash dividend),
stock split, or other change in corporate  structure affecting the Common Stock,
a corresponding substitution or adjustment shall be made in the

                                                        -3-





maximum  aggregate number of shares for which Stock Options may be granted under
this  Plan,  in the number and  option  price of shares  subject to  outstanding
Options  granted under this Plan, as may be determined to be  appropriate by the
Committee, in its sole discretion, provided that the number of shares subject to
any Stock Option shall always be a whole number.


                                                     ARTICLE V

                                                    Eligibility

                  5.1  Stock  Options  may  be  granted  only  to  persons  who,
immediately prior to the Merger,  hold a BHC Option, and only in conversion of a
BHC Option pursuant to the Merger Agreement.


                                                    ARTICLE VI

                                              Award of Stock Options

                  6.1      Options.  Each Stock Option granted under this Plan
shall be either an Incentive Stock Option or a Non-Qualified Stock Option.

                  6.2 Grants. On the effective date of the Merger, the Committee
shall  grant to each  person  who holds a BHC Option in  conversion  of such BHC
Option a Stock  Option to purchase  such number of shares of Common  Stock (with
any fractional share being  disregarded) as shall be equal to the product of the
number of shares of BHC Financial  common stock subject to such BHC Option being
converted  multiplied  by the  Conversion  Ratio.  No other Stock  Option may be
granted under the Plan.

                  6.3  Incentive  Stock  Options.  Anything  in the  Plan to the
contrary  notwithstanding,  no term of this Plan  relating  to  Incentive  Stock
Options shall be  interpreted,  amended or altered,  nor shall any discretion or
authority  granted  under the Plan be exercised,  so as to  disqualify  the Plan
under  section 422 of the Code,  or,  without  the  consent of the  Participants
affected, to disqualify any Incentive Stock Option under such section 422.

                  6.4      Terms of Options.  Stock Options granted under this
Plan in  conversion  of a BHC  Option  shall be  subject  to the same  terms and
conditions as the BHC Option being converted; provided, however, that

                           (a)      Option Price.  The option price per share of
Common  Stock  purchasable  under a Stock  Option shall be equal to the quotient
determined  by  dividing  the  option  price per share of such BHC Option by the
Conversion Ratio, and rounding upward to the nearest full cent.

                                                        -4-





                           (b)      Number of Shares.  The number of shares of
Common Stock subject to the Stock Option shall be determined pursuant to Section
6.2.

                           (c)      Option Term.  The term of each Stock Option
shall be for the remaining  term of the BHC Option being  converted,  subject to
earlier termination as provided herein or in the BHC Option.

                           (d)      Exercisability.  All Stock Options shall be
immediately exercisable.

                           (e)      Method of Exercise.  Stock Options may be
exercised  in whole or in part at any time  during  the option  term,  by giving
written notice of exercise to the Company  specifying the number of shares to be
purchased.  Such notice shall be  accompanied by payment in full of the purchase
price in such form as the Committee may accept.  If and to the extent determined
by the Committee in its sole discretion at any time,  payment in full or in part
may also be made in the form of Common Stock duly owned by the Participant  (and
for  which  the  Participant  has good  title  free and  clear of any  liens and
encumbrances),  or by  reduction  in the  number  of shares  issuable  upon such
exercise  based,  in each case, on the Fair Market Value of the stock. No shares
of Common Stock shall be issued until payment, as provided herein,  therefor has
been made. A Participant  shall  generally have the rights to dividends or other
rights of a  shareholder  with respect to shares  subject to the Option when the
optionee  has given  written  notice of  exercise,  has paid for such  shares as
provided herein,  and, if requested,  has given the representation  described in
Section 9.1.

                           (f)      Non-Transferability of Options.  No Stock
Option shall be transferable by the Participant otherwise than by will or by the
laws of descent and distribution, to the extent consistent with the terms of the
Plan and the Option,  and all Stock  Options  shall be  exercisable,  during the
Participant's lifetime, only by the Participant.

                           (g)      Termination by Death.  Subject to Subsection
(k), if a Participant's  employment by the Company or a Designated Subsidiary of
the Company  terminates by reason of the  Participant's  death, any Stock Option
held by such Participant may thereafter be exercised by the legal representative
of the  Participant's  estate  until the  expiration  of the option term of such
Stock Option.

                           (h)      Termination by Reason of Disability.
Subject to  Subsection  (k), if a  Participant's  employment by the Company or a
Designated  Subsidiary of the Company  terminates by reason of the Participant's
Disability,  any  stock  Option  held  by such  Participant  may  thereafter  be
exercised by the  Participant  until the  expiration  of the stated term of such
Stock Option; provided,  however, that, if the Participant dies before the Stock
Option is exercised, any unexercised Stock Option held by such Participant shall
thereafter  be  exercisable  by the legal  representative  of the  Participant's
estate  until the  expiration  of the option term of such Stock  Option.  In the
event of termination of employment by reason of the Participant's Disability, if
an  Incentive  Stock Option is exercised  after the  expiration  of the exercise
periods  that apply for  purposes of section 422 of the Code,  such Stock Option
will thereafter be treated as a Non-Qualified Stock Option.


                                                        -5-





                           (i)      Termination by Reason of Retirement.
Subject to  Subjection  (k), if a  Participant's  employment by the Company or a
Designated  Subsidiary of the Company  terminates by reason of the Participant's
Retirement,  any  Stock  Option  held  by such  Participant  may  thereafter  be
exercised by the  Participant  until the  expiration  of the option term of such
Stock Option; provided,  however, that, if the Participant dies after Retirement
but before the Stock Option is exercised,  any unexercised  Stock Option held by
such Participant shall thereafter be exercisable by the legal  representative of
the  Participant's  estate until the expiration of the option term of such Stock
Option. In the event of termination of employment by reason of the Participant's
Retirement,  if an Incentive  Stock Option is exercised  after the expiration of
the exercise  periods  that apply for purposes of Section 422 of the Code,  such
Stock Option will thereafter be treated as a Non-Qualified Stock Option.

                           (j)      Other Termination.  Unless otherwise
determined by the Committee at any time,  if a  Participant's  employment by the
Company or a  Designated  Subsidiary  of the Company  terminates  for any reason
other than the Participant's death,  Disability or Retirement,  the Stock Option
shall  thereupon  terminate,  except that such Stock Option may be exercised for
the lesser of three  months or the  balance of such Stock  Option's  term if the
Participant is involuntarily terminated without cause.

                           (k)      Buyout and Settlement Provisions.  The
Committee  may at any time offer to buy out a Stock Option  previously  granted,
based  on such  terms  and  conditions  as the  Committee  shall  establish  and
communicate to the Participant at the time that such offer is made. In addition,
if the Stock Option  agreement so provides or is amended prior to exercise to so
provide (with the Participant's  consent), the Committee may require that all or
part of the shares to be issued with respect to the spread value of an exercised
Stock Option take the form of  performance  shares or  restricted  stock,  which
shall be valued on the date of exercise on the basis of the fair market value of
such performance  shares or restricted  stock  determined  without regard to the
deferral limitations and/or forfeiture restrictions involved.

                  6.6 Rights as Shareholders. Unless otherwise determined by the
Committee,  a Participant shall not have any right as a shareholder with respect
to any  shares  subject  to his  Stock  Options  until  the  issuance  of  stock
certificates to him or her for such shares.


                                                    ARTICLE VII

                                       Termination or Amendment of the Plan

                  7.1      Termination or Amendment.

                           (a)      The Board may at any time amend, discontinue
or  terminate  this Plan or any part thereof  (including  any  amendment  deemed
necessary to ensure that the Company may comply with any regulatory  requirement
referred to in Article IX); provided, however, that, unless

                                                        -6-





otherwise  required by law,  the rights of a  Participant  with respect to Stock
Options granted prior to such amendment,  discontinuance or termination, may not
be impaired  without  the consent of such  Participant  and,  provided  further,
without the approval of the  Company's  stockholders,  no amendment  may be made
which would (i)  increase  the  aggregate  number of shares of Common  Stock for
which  Stock  Options may be granted  under this Plan  (except by  operation  of
Section  4.2) or (ii) change the  definition  of persons  eligible to be granted
Stock Options under this Plan.

                           (b)      The Committee may amend the terms of any
Stock Options theretofore granted, prospectively or retroactively,  but, subject
to Article IV above,  no such  amendment or other action by the Committee  shall
impair the rights of any holder without the holder's consent.


                                                   ARTICLE VIII

                                                   Unfunded Plan

                  8.1  Unfunded  Status  of  Plan.  This  Plan  is  intended  to
constitute  an  "unfunded"  plan of incentive  and deferred  compensation.  With
respect to any payment not yet made to a  Participant  by the  Company,  nothing
contained  herein  shall give any such  Participant  any rights that are greater
than those of a general creditor of the Company.


                                                    ARTICLE IX

                                                General Provisions

                  9.1 Legend.  The Committee may require each person  purchasing
shares  pursuant to a Stock Option under the Plan to represent to and agree with
the Company in writing that the  Participant  is acquiring the shares  without a
view to distribution  thereof.  In addition to any legend required by this Plan,
the  certificates  for such shares may include  any legend  which the  Committee
deems appropriate to reflect any restrictions on transfer.

                           All certificates for shares of Common Stock delivered
under  the Plan  shall be  subject  to such  stock  transfer  orders  and  other
restrictions  as the Committee may deem advisable  under the rules,  regulations
and other  requirements  of the  Securities and Exchange  Commission,  any stock
exchange upon which the Common Stock is then listed,  any applicable  Federal or
state  securities  law, and any applicable  corporate law, and the Committee may
cause a legend or legends to be put on any such certificates to make appropriate
reference to such restrictions.

                  9.2 Other Plans.  Nothing contained in this Plan shall prevent
the Board from adopting other or additional compensation  arrangements,  subject
to shareholder approval if such approval is required;  and such arrangements may
be either generally applicable or applicable only in specific cases.

                                                        -7-





                  9.3 No Right to Employment. Neither this Plan nor the grant of
any  Stock  Option  hereunder  in  conversion  of a BHC  Option  shall  give any
Participant  or  other  employee  any  right  with  respect  to  continuance  of
employment  by the  Company  or any of its  subsidiaries,  nor shall  there be a
limitation in any way on the right of the Company or any  subsidiary by which an
employee is employed to terminate his employment at any time.

                  9.4 Withholding of Taxes.  The Company shall have the right to
deduct  from any  payment  to be made  pursuant  to this Plan,  or to  otherwise
require,  prior to the issuance or delivery of any shares of Common Stock or the
payment of any cash hereunder,  payment by the Participant of any Federal, state
or local taxes required by law to be withheld. The Committee may permit any such
withholding  obligation  to be  satisfied  by  reducing  the number of shares of
Common  Stock  otherwise  deliverable.  Any  fraction of a share of Common Stock
required to satisfy such tax obligation  shall be disregarded and the amount due
shall be paid instead in cash by the Participant.

                  9.5 No Assignment of Benefits.  No Stock Option  granted under
this Plan shall, except as otherwise specifically required by law, be subject in
any manner to anticipation,  alienation, attachment, sale, transfer, assignment,
pledge, encumbrance or charge, and any attempt to anticipate,  alienate, attach,
sell,  transfer,  assign,  pledge,  encumber or charge any such benefit shall be
void,  and any such benefit  shall not in any manner be liable for or subject to
the debts, contracts, liabilities,  engagements or torts of any person who shall
be  entitled to such  benefit,  nor shall it be subject to  attachment  or legal
process for or against such person.

                  9.6      Listing and Other Conditions.

                           (a)      If and as long as the Common Stock is listed
on national  securities  exchange or system  sponsored by a national  securities
association,  the issue of any shares of Common Stock pursuant to a Stock Option
shall be  conditioned  upon such shares being listed on such exchange or system.
The Company  shall have no obligation to issue such shares unless and until such
shares are so listed, and the right to exercise any Stock Option with respect to
such shares shall be suspended until such listing has been effected.

                           (b)      If at any time counsel to the Company shall
be of the opinion that any sale or delivery of shares of Common  Stock  pursuant
to an  Option  is or may in the  circumstances  be  unlawful  or  result  in the
imposition  of excise  taxes under the  statutes,  rules or  regulations  of any
applicable jurisdiction,  the Company shall have no obligation to make such sale
or  delivery,  or to make  any  application  or to  effect  or to  maintain  any
qualification or registration  under the Securities Act of 1933, as amended,  or
otherwise with respect to shares of Common Stock,  and the right to exercise any
Stock Option shall be suspended until, in the opinion of said counsel, such sale
or delivery shall be lawful.

                           (c)      Upon termination of any period of suspension
under this Section 9.6, any Stock Option affected by such suspension which shall
not then  have  expired  or  terminated  shall be  reinstated  as to all  shares
available before such suspension and as to shares which would otherwise

                                                        -8-





have  become  available  during  the  period  of  such  suspension,  but no such
suspension shall extend the term of any Stock Option.

                  9.7  Governing  Law. This Plan and actions taken in connection
herewith  shall be governed  and  construed in  accordance  with the laws of the
State of  Wisconsin  (regardless  of the law that might  otherwise  govern under
applicable Wisconsin principles of conflict of laws).

                  9.8 Construction.  Wherever any words are used in this Plan in
