Agreement, during the term of this Agreement, Executive shall devote
substantially his full business time to the discharge of his duties and
responsibilities under this Agreement, except for vacations in accordance with
this Agreement and with Employer's vacation policy applicable to executive
personnel. This provision shall not prevent Executive from devoting a reasonable

         During the term of this Agreement, Executive shall be entitled to an

discretion. The Board of Directors may also increase Executive's compensation at
any other time, in its absolute discretion. Executive shall also be entitled to
receive incentive compensation which compensation shall be calculated in
accordance with the provisions of Employer's incentive compensation plan, as in
effect from time to time. Executive's base salary shall be payable periodically

normal practice of Employer and his incentive compensation shall be payable as

benefit of the Executive, who shall be entitled to designate all beneficiaries
of such life insurance.

         (d) Employer shall maintain medical and dental insurance on such terms
and in such amounts as are generally offered to or provided for any other

         (h) Notwithstanding the foregoing, Executive shall not be entitled to
participate in any employee benefit plans or programs offered by an affiliate of
the Employer.

1.6      Officers Insurance.

         For so long as Executive shall be an officer of Employer, Employer
shall use its best efforts to provide Executive with insurance coverage against
business liability to the extent that such coverage is reasonably available for
officers of financial institutions of comparable size.

1.7      Indemnity by Employer.

                                   ARTICLE II

                            TERMINATION OF EMPLOYMENT

2.1      Termination at Expiration of the Term of this Agreement.

         (a) If Executive elects to terminate Executive's employment with
Employer at the end of the initial three-year term under Section 1.1, Executive
shall be entitled to receive (i) Executive's theretofore unpaid base salary and
incentive compensation for the period of employment, and (ii) compensation for
accrued but unused vacation time. Executive and his spouse and dependents will
be entitled to further medical coverage, at his and/or their expense, to the
extent required by the Consolidated Omnibus Reconciliation Act of 1985
("COBRA").

         (b) If the Employer elects to terminate Executive's employment with
Employer at the end of the initial three-year term under Section 1.1, Executive
shall be entitled to receive (i) an amount equal to two times his annual base
salary at the date of termination, (ii) Executive's theretofore unpaid base
salary and incentive compensation for the period of employment, and (iii)
compensation for accrued but unused vacation time. Executive shall be owed and
Employer shall be obligated to pay to Executive the aggregate amount provided in
clauses (i), (ii) and (iii) above (other than incentive compensation which shall
be payable when earned as provided in Section 1.3 hereof), within thirty (30)
days after the termination of Executive pursuant to this Section 2.1(b), and
until such amounts are paid in full to Executive, interest shall accrue on said
amount as of the date first due at the rate of eighteen percent (18%) per annum,
compounded daily. Furthermore, at Employer's cost, Employer shall continue to
provide Executive with the following benefits, consistent with the terms and
conditions set forth in Section 1.5 hereof: (i) life insurance and medical,
dental and optical insurance, to the extent the same can be provided under the
arrangements in effect at the time of termination, and (ii) any other benefits
to which Executive is entitled by law

                                        4

<PAGE>   5

or the specific terms of Employer's policies in effect at the time of his
termination of employment. Benefits will be continued pursuant to this Section
2.1(b) for a period of twelve (12) months from the date of termination of
employment, unless Executive becomes employed by another company and becomes
eligible for employment benefits substantially similar to those which would
otherwise be provided under this Section. Notwithstanding the foregoing,
Executive and his spouse and dependent children will be entitled, at Executive's
expense, to further medical coverage to the extent required by COBRA which
shall, in this case, be deemed to commence upon expiration of the twelve (12)
month period set forth in the preceding sentence. Notwithstanding anything
contained herein to the contrary, if Executive becomes unable to perform each of
the material duties of his employment under this Agreement prior to his
termination of employment pursuant to this paragraph (b), and Executive
thereafter, as a result of the same condition, becomes Totally and Permanently
Disabled as defined in Section 2.3, Executive will be entitled to the Full
Disability Benefits (as defined in Section 2.3) provided for in Section 2.3 upon
his termination of employment.

2.2      Termination for Death or Retirement.

         If Executive's employment is terminated by reason of Executive's
retirement or death then Executive, or Executive's personal representative, as
the case may be, shall be entitled to receive (a) Executive's theretofore unpaid
base salary and incentive compensation for the period of employment, prorated to
the end of the calendar month in which such termination occurs, and (b)
compensation for accrued but unused vacation time. Employer shall pay the
amounts due under this Section 2.2 to Executive or Executive's personal
representative within thirty (30) days of Executive's retirement or death, as
the case may be. Executive's spouse and dependent children shall continue to be
entitled, at the expense of Employer in the case of death and at the expense of
Executive in the case of retirement, to further medical coverage to the extent
required by COBRA. The term "retirement" for purposes of this Agreement shall
mean the point in time after the Executive reaches 55 years of age and at which
Executive gives notice to Employer that he is retiring.

2.3      Termination for Disability.

         If Executive becomes Totally and Permanently Disabled during the term
of this Agreement, Executive's employment may be terminated by the Employer at
any time during the continuance of such disability. The Executive is Totally and
Permanently Disabled if he is unable to perform each of the material duties of
his employment under this Agreement, by reason of any disability, illness,
accident or condition, for a period of more than six consecutive months during
any twelve-month period, which is expected to continue for more than one year as
certified by a medical doctor of Executive's own choosing and concurred in by a
doctor of Employer's choosing.

         Upon termination as described in this Section 2.3, Executive shall be
entitled to receive (a) an amount equal to one hundred percent (100%) of
Executive's annual base salary at the date of termination, (b) Executive's
theretofore unpaid base salary and incentive compensation for the period of
employment, prorated to the end of the calendar month in which such termination
occurs, and (c) compensation for accrued but unused vacation time. In addition,
at Employer's cost, Employer shall

                                        5

<PAGE>   6

continue to provide Executive with the following benefits, consistent
with the terms and conditions set forth in Section 1.5 hereof: (i) life
insurance and medical, dental and optical insurance, to the extent the
same can be provided under the arrangements in effect at the time of
termination, and (ii) any other benefits to which the Executive is
entitled by law or the specific terms of Employer's policies in effect at
the time of his termination of employment. Benefits will be continued
pursuant to this Section 2.3 for a period of twelve (12) months from the
date of termination of employment, unless Executive becomes employed by
another company and becomes eligible for employment benefits
substantially similar to those which would otherwise be provided under
this Section. Notwithstanding the foregoing, Executive and his spouse and
dependent children shall continue to be entitled, at Executive's expense,
to further medical coverage to the extent required by COBRA. In addition
to the foregoing, Employer and Executive intend that Executive will
receive benefits upon his termination of employment pursuant to this
Section 2.3 (or upon his termination of employment pursuant to an
election by Employer under Section 1.1, if Executive becomes unable to
perform each of the material duties of his employment under this
Agreement prior to such termination of employment, and Executive
thereafter, as a result of the same condition, becomes Totally and
Permanently Disabled) comparable in amount to those Executive would
receive under Employer's current short-term and long-term disability
plans as if the maximum benefit limitation did not apply (such benefits
referred to hereafter as "Full Disability Benefits"). Full Disability
Benefits shall be provided through the end of the Severance Period as
defined in Section 2.5. Employer may obtain and maintain insurance
coverage to provide for the Full Disability Benefits, which insurance
coverage may include insured benefits under the Employer's short-term and
long-term disability plans for executives (all such insurance referred to
hereafter as "Disability Insurance"). To the extent that the payments to
Executive under the Disability Insurance are less than the payments due
under the Full Disability Benefits, Employer shall be obligated to
provide the amount of such deficiency out of its general funds. Such
deficiency shall be paid by Employer to Executive in the form of a
monthly supplement to any Disability Insurance payments.

2.4      Voluntary Termination by Executive or Termination by Employer for
         Cause.

         Employer may terminate Executive's employment hereunder for cause (as
such term is defined below). If Executive's employment is voluntarily terminated
by Executive or is terminated by Employer for cause, Executive shall be entitled
to receive (a) Executive's theretofore unpaid base salary and incentive
compensation for the period of employment, prorated to the date of termination,
and (b) compensation for accrued but unused vacation time, but shall not be
entitled to any compensation or employment benefits pursuant to this Agreement
for any period after the date of termination, or the continuation of any
benefits except as may be required by law, including, at his own expense, COBRA.

         Termination by Employer for cause shall mean termination because of the
Executive's Personal Dishonesty (as hereinafter defined), Incompetence (as
hereinafter defined), Willful Misconduct (as hereinafter defined), breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule, or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order, or material
breach of any provision

                                        6

<PAGE>   7

of this Agreement; provided, however, in the event Employer determines that
Executive has intentionally failed to perform his stated duties or materially
breached this Agreement, Employer may not terminate Executive for cause unless
Employer has notified Executive of such failure or breach, Executive has been
given a reasonable period of time to cure such failure or breach, and in the
opinion of Employer, Executive has not cured such failure or breach. For the
purpose of this Agreement: (i) "Incompetence" means Executive's demonstrated
lack of ability to perform the duties assigned to him which lack of ability
directly causes (or the Board of Directors determines is reasonably likely to
cause) material injury to Employer; (ii) "Personal Dishonesty" means conduct on
the part of Executive which evinces a want of integrity or an intentional breach
of trust and which directly causes (or the Board of Directors determines is
reasonably likely to cause) material injury to Employer; and (iii) "Willful
Misconduct" means conduct on the part of Executive which evinces a deliberate
disregard of the interest of Employer and which causes (or the Board of
Directors determines is reasonably likely to cause) direct material injury to
Employer.

2.5      Termination by Employer Without Cause or Termination by Executive for
         Cause.

         (a) In the event Employer reduces Executive's base compensation,
responsibilities or duties without Executive's consent or otherwise breaches
this Agreement, Executive may elect to terminate this Agreement for cause. In
the event Employer terminates Executive other than under Section 2.1 (expiration
of the term), Section 2.2 (death/retirement), Section 2.3 (disability) or
Section 2.4 (voluntary termination by Executive or termination by Employer for
cause) or Executive elects to terminate his employment hereunder for cause, then
in either such event Executive shall receive (i) one hundred percent (100%) of
his annual base salary at the time of termination through the end of the
Severance Period (as hereinafter defined) (ii) Executive's theretofore unpaid
base salary and incentive compensation, prorated to the end of the calendar
month in which such termination occurs, and (iii) compensation for accrued but
unused vacation time. Executive shall be owed, and Employer shall be obligated
to pay to Executive, the entire amount provided in clauses (i), (ii) and (iii)
above (other than incentive compensation which shall be payable within the
period of time provided in Section 1.3) within thirty (30) days after the
termination of Executive pursuant to this Section 2.5, and until such amount is
paid in full to Executive, interest shall accrue on said amount as of the date
first due at the rate of eighteen percent (18%) per annum, compounded daily. For
purposes of this Agreement, the "Severance Period" shall be as follows: if the
termination shall occur within the initial three year employment term of this
Agreement, the Severance Period shall be three years; if the termination shall
occur within the first year after the expiration of the initial three year
employment term, the Severance Period shall be two years; and if the termination
shall occur more than one year after the expiration of the initial three year
employment term, the Severance Period shall be one year.

         (b) Furthermore, if Employer terminates Executive pursuant to this
Section 2.5, at Employer's cost, Employer shall continue to provide Executive
with the following benefits, consistent with the terms and conditions set forth
in Section 1.5 hereof: (i) life insurance and medical, dental and optical
insurance, to the extent the same can be provided under the arrangements in
effect at the time of termination, and (ii) any other benefits to which
Executive is entitled by law or the

                                        7

<PAGE>   8

specific terms of Employer's policies in effect at the time of his termination
of employment. Benefits will be continued pursuant to this Section 2.5 through
the end of the Severance Period, unless Executive becomes employed by another
company and is eligible for employment benefits substantially similar to those
which would otherwise be provided under this Section. Notwithstanding the
foregoing, Executive and his spouse and dependent children will be entitled, at
Executive's expense, to further medical coverage to the extent required by COBRA
which shall, in this case, be deemed to commence upon expiration of the period
set forth in the preceding sentence.

         (c) If Employer terminates Executive pursuant to this Section 2.5, the
Executive shall also be entitled to receive an additional benefit. Such benefit
shall be a single sum cash payment in an amount equal to the product of the
Employer's annual aggregate contribution, for the benefit of the Executive in
the year preceding termination, to all qualified retirement plans in which the
Executive participated multiplied by the number of years in the Severance
Period. Such benefit shall be in addition to any benefit payable from any
qualified or nonqualified plans or programs maintained by the Employer at the
time of termination.

2.6      Termination by Executive Due to Change in Control.

         (a) Following a Change in Control (as hereinafter defined), Executive
may, by giving notice to Employer, immediately terminate his employment under
this Agreement upon the occurrence of any of the following:

         (i) any reduction in Executive's base or incentive compensation, or
employee benefits described in Section 1.4, 1.5, 1.6 and 1.7 and provided to
Executive immediately preceding a Change in Control (other than changes in
benefits required by law and applicable to all employees generally), or any
assignment to any position, responsibilities or duties that are less significant
than his position, duties and responsibilities as of the time immediately
preceding a Change in Control;

         (ii) a transfer of Executive by Employer requiring Executive to have
his principal location of work more than fifty (50) miles from Executive's
principal location of work immediately prior to the Change in Control; or

         (iii) a requirement by Employer that Executive travel materially more
than that amount of time which has historically been required by Employer such
that Executive is required to be away from his place of residence for more than
three weekends in a calendar year or for four or more week nights per week
during any three weeks in a calendar year.

         If Executive terminates this Agreement pursuant to this Section 2.6,
Executive shall have the right to receive payments and benefits under, and to
the extent provided by, Section 2.5 as if a termination by Employer without
cause had occurred. In addition, Executive shall be entitled to the continued
full-time use of an Employer-owned or leased automobile, membership in a service
and recreational club for a period of twelve (12) months from the date of
termination of employment.

                                        8

<PAGE>   9

         (b) For purposes of this Agreement, a "Change in Control" shall be
deemed to have occurred if: (1) any "person" (as such term is used in Section
13(d) and 14(d)(2) of the Securities Exchange Act of 1934) other than MHC or the
Company becomes the owner of securities of the Employer, or any person other
than MHC becomes the beneficial owner, directly or indirectly, of a majority of
the capital stock of the Company in a transaction or transactions subject to the
notice provisions of the Change in Bank Control Act of 1978, (12 USC ss.
1817(j)) as amended from time to time, or approval under the Savings and Loan
Holding Company Act (12 USC ss. 1467a), as amended from time to time; (2)
someone other than the Company or MHC becomes owner of more than 25% of the
voting securities of the Employer; (3) during any period of two (2) consecutive
years, the individuals, who at the beginning of any such period constituted the
directors of the Employer or the Company, cease for any reason to constitute at
least a majority thereof; or (4) the filing by the Company of a report or proxy
statement with the Securities and Exchange Commission of the Office of Thrift
Supervision disclosing in response to Item 1 of Form 8-K or Item 5 of Part II of
Form 10-Q, each promulgated pursuant to the Securities Exchange Act of 1934, as
amended ("Exchange Act") or Item 6(e) of Schedule 14A promulgated thereunder, or
successor Items, that a change in control of the Company has or may have
occurred pursuant to any contract or transaction.

         However, notwithstanding the foregoing provisions, the following events
or occurrences shall not constitute a "Change in Control" hereunder:

         (i) The merger, consolidation or other combination of the Employer
with, or sale of the Employer to, or assumption of the Employer by any company
controlled by, controlling or under control with the Company or the MHC if the
entity with which the Employer is combined assumes this Agreement, in which
event such successor shall be deemed to be the "Employer" hereunder.

         (ii) A further reorganization of the Company and MHC in which the
shareholders of the Company prior to such reorganization, the members of MHC and
any members of the public, which acquire shares of such entity pursuant to a
public offering of securities approved in advance by the board of directors of
MHC, together control the successor entity, in which event such successor entity
shall then be deemed to be the "Company" hereunder.

2.7      Termination or Suspension as Required by Law.

         (a) If the Executive is suspended and/or temporarily prohibited from
participating in the conduct of the Employer's affairs by a notice serviced
under section 8 (e)(3) or (g)(1) of the FDIA (12 U.S.C. 1818(e)(3) and (g)(1))
the Employer's obligations under this Agreement shall be suspended as of the
date of service unless stayed by appropriate proceedings. If the charges in the
notice are dismissed, the Employer may in its discretion (i) pay the Executive
all or part of the severance benefit withheld while its contract obligations
were suspended, and (ii) reinstate (in whole or in part) any of its obligations
which were suspended.

                                        9

<PAGE>   10

         (b) If the Executive is removed and/or permanently prohibited from
participating in the conduct of the Employer's affairs by an order issued under
section 8 (e)(4) or (g)(1) of the FDIA (12 U.S.C. 1818 (e)(4) or (g)(1)), all
obligations of the Employer under this Agreement shall terminate as of the
effective date of the order, but vested rights of the Executive and the Employer
shall not be affected.

         (c) If the Employer is in default (as defined in section 3(x)(1) of the
FDIA, all obligations under this Agreement shall terminate as of the date of
default, but this Section 2.7 shall not affect any vested rights of the
Executive or the Employer.

         (d) All obligations under this Agreement shall be terminated except to
the extent determined that continuation of the contract is necessary for the
continued operation of the Employer.

                           (i) By the Director of the Office of Thrift
         Supervision (the "Director") or his or her designee, at the time the
         Federal Deposit Insurance Corporation or Resolution Trust Corporation
         enters into an agreement to provide assistance to or on behalf of the
         Employer under the authority contained in 13(c) of the FDIA; or

                           (ii) By the Director or his or her designee, at the
         time the Director or his or her designee approves a supervisory merger
         to resolve problems related to operation of the Employer or when the
         Employer is determined by the Director to be in an unsafe or unsound
         condition.

                  Any rights of the Executive which have vested, including those
         which vest pursuant to this Agreement, shall not be affected by such
         action.

2.8      Successors and Binding Agreements.

         (a) This Agreement shall be binding upon and inure to the benefit of
Employer and any Successor of or to Employer, but shall not otherwise be
assignable or delegatable by Employer. "Successor" shall mean any successor in
interest, including, without limitation, any entity, individual or group of
persons acquiring directly or indirectly all or substantially all of the
business or assets of Employer whether by sale, merger, consolidation,
reorganization or otherwise.

         (b) This Agreement shall inure to the benefit of and be enforceable by
Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees and legatee.

         (c) Employer shall require any Successor to agree (in such form as is
reasonably requested by Executive) to perform this Agreement to the same extent

         (d) This Agreement is personal in nature and neither of the parties
shall, without the consent of the other, assign, transfer or delegate this
Agreement or any rights or obligations hereunder except as expressly provided in
this Section 2.8.

2.9      Limitations on Termination Compensation.

         (a) In the event that the severance benefits payable to the Executive
under Sections 2.5, or 2.6 ("Severance Benefits"), or any other payments or
benefits received or to be received by the Executive from the Employer (whether
payable pursuant to the terms of this Agreement or any other plan, agreement or
arrangement with the Employer) or any corporation ("Affiliate") affiliated with
the Employer within the meaning of Section 1504 of the Internal Revenue Code of
1986, as amended (the "Code"), in the opinion of tax counsel selected by the
Employer's independent auditors and acceptable to the Executive, constitute
"parachute payments" within the meaning of Section 280G(b)(2) of the Code, and
the present value of such "parachute payments" equals or exceeds three (3) times
the average of the annual compensation payable to the Executive by the Employer
(or an Affiliate) and includible in the Executive's gross income for federal
income tax purposes for the five (5) calendar years preceding the year in which
a change in ownership or control of the Employer occurred ("Base Amount"), such
Severance Benefits shall be reduced to an amount the present value of which
(when combined with the present value of any other payments or benefits
otherwise received or to be received by the Executive from the Employer (or an
Affiliate) that are deemed "parachute payments") is equal to 2.99 times the Base
Amount, notwithstanding any other provision to the contrary in this Agreement.
The Severance Benefits shall not be reduced if (A) the Executive shall have
effectively waived his receipt or enjoyment of any such payment or benefit which
triggered the applicability of this Section 2.9, or (B) in the opinion of tax
counsel, the Severance Benefits (in its full amount or as partially reduced, as
the case may be) plus all other payments or benefits which constitute "parachute
payments" within the meaning of Section 280G(b)(2) of the Code are reasonable
compensation for services actually rendered, within the meaning of Section
280G(b)(4) of the Code, and such payments are deductible by the Employer. The
Base Amount shall include every type and form of compensation includible in the
Executive's gross income in respect of his employment by the Employer (or an
Affiliate), except to the extent otherwise provided in temporary or final
regulations promulgated under Section 280G(b) of the Code. For purposes of this
Section 2.9, a "change in ownership or control" shall have the meaning set forth
in Section 280G(b) of the Code and any temporary or final regulations
promulgated thereunder. The present value of any non-cash benefit or any
deferred cash payment shall be determined by the Employer's independent auditors
in accordance with the principles of Sections 280G(b)(3) and (4) of the Code.

         (b) The Executive shall have the right to request that the Employer
obtain a ruling from the Internal Revenue Service ("Service") as to whether any
or all payments or benefits determined by such tax counsel are, in the view of
the Service, "parachute payments" under Section 280G. If a ruling is sought
pursuant to the Executive's request, no Severance Benefits payable under this
Agreement shall be made to the Executive until after fifteen (15) days from the
date of such ruling. For purposes of this Section 2.9(b), the Executive and the
Employer agree to be bound by the Service's ruling as to whether payments
constitute "parachute payments" under Section 280G. If the

                                       11

<PAGE>   12

Service declines, for any reason, to provide the ruling requested, the tax
counsel's opinion provided in Subsection 2.9(a) with respect to what payments or
benefits constitute "parachute payments" shall control, and the period during
which the Severance Benefits may be deferred shall be extended to a date fifteen
(15) days from the date of the Service's notice indicating that no ruling would
be forthcoming.

         (c) In the event that Section 280G, or any successor statute, is
repealed, this Section 2.9 shall cease to be effective on the effective date of
such repeal. The parties to this Agreement recognize that final regulations
under Section 280G of the Code may affect the amounts that may be paid under
this Agreement and agree that, upon issuance of such final regulations, this
Agreement may be modified as in good faith deemed necessary in light of the
provisions of such regulations to achieve the purposes of this Agreement, and
that consent to such modifications shall not be unreasonably withheld.

         (d) Any payments made to the Executive pursuant to this Agreement, or
otherwise, are subject to and conditioned upon their compliance with section
18(k) of the Federal Deposit Insurance Act (12 USC ss. 1828(k)) and any
regulations promulgated thereunder.

                                   ARTICLE III

                                 NONCOMPETITION

3.1      Noncompetition.

         (a) While the Executive is employed by the Employer and during the
Post-Employment Noncompetition Period (as defined below), Executive will not
directly or indirectly as a principal, agent, owner, employee, consultant,
trustee, beneficiary, distributor, partner, co-venturer, officer, director,
stockholder or in any other capacity:

                  (i) own, operate, manage, join, finance, control, participate
in ownership, management, operation or control of, or be paid or employed by or
acquire any securities of, or otherwise become associated with or provide
assistance to any Significant Competitor of the Employer. For purposes of this
Agreement, the term Significant Competitor means any financial institution
including, but not limited to, any commercial bank, savings bank, savings and
loan association, credit union, or mortgage banking corporation which, at the
time of termination of Executive's employment with the Employer, or during the
period of this covenant not to compete, has a home, branch or other office in
Brown County or within 50 miles of Executive's principal place of employment
immediately prior to Executive's termination of employment.

                  (ii) divert or attempt to divert any business from the
Employer or engage in any act likely to cause any present or future customer or
supplier of the Employer to discontinue or curtail its business with the
Employer or to do business with another entity, firm, business, activity or
enterprise directly or indirectly competitive with the Employer;

                                       12

<PAGE>   13

                  (iii) contact, sell or solicit to sell, or attempt to contact,
sell or solicit to sell products or services competitive with those of the
Employer to any present or future customer of the Employer with which Executive
has had contact while performing services hereunder for the Employer; or

                  (iv) solicit, cause or seek to cause any employee of the
Employer to terminate, curtail or otherwise modify his or her employment
relationship with the Employer for the purpose of entering into an employment or
other relationship with Executive or with any entity, firm, business, activity
or enterprise with which Executive is directly or indirectly affiliated.

         For purposes of this Agreement, the Post-Employment Noncompetition
Period shall be the greater of one year or the period for which Executive has
received post-employment compensation under Article II (i.e., two years for a
termination under Section 2.1(b) and the Severance Period for a termination
under Section 2.5 or Section 2.6); provided that the Post-Employment
Noncompetition Period shall not exceed two years.

         (b) Notwithstanding the provisions of Section 3.1(a) hereof, Executive
may:

                  (i) acquire securities of any entity the securities of which
are publicly traded, provided that the value of the securities of such entity
held directly or indirectly by Executive immediately following such acquisition
is less than 5% of the total value of the then outstanding class or type of
securities acquired; and

                  (ii) perform services for a business which is similar to or
competitive with the Employer if such company is also engaged in another
business which is not similar to or competitive with the Employer and
Executive's services are restricted to such other business to the reasonable
satisfaction of the Employer provided the Employer approves in writing of such
services, which approval shall not be unreasonably withheld.

         (c) Executive acknowledges and agrees that the restrictions set forth
in this Section 3.1 are founded on valuable consideration and are reasonable in
duration and geographic area in view of the circumstances under which this
Agreement is executed and that such restrictions are necessary to protect the
legitimate interests of the Employer. In the event that any provision of this
Section 3.1 is determined to be invalid by any court of competent jurisdiction,
the provisions of this Section 3.1 shall be deemed to have been amended and the
parties will execute any documents and take whatever action is necessary to
evidence such amendment, so as to eliminate or modify any such invalid provision
and to carry out the intent of this Section 3.1 so to render the terms of this
Section 3.1 enforceable in all respects as so modified.

         (d) Executive acknowledges and agrees that irreparable injury will
result to the Employer in the event Executive breaches any covenant contained in
this Section 3.1 and that the remedy at law for such breach will be inadequate.
Therefore, if Executive engages in any act in violation of the provisions of
this Section 3.1, the Employer shall be entitled, in addition to such other
remedies

                                       13

<PAGE>   14

and damages as may be available to it by law or under this Agreement, to
injunctive or other equitable relief to enforce the provisions of this Section
3.1.

                                   ARTICLE IV

                             LEGAL FEES AND EXPENSES

         It is the intent of Employer that Executive not be required to incur
the expenses associated with the enforcement of his rights under this Agreement
by litigation, arbitration or other legal action because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
Executive hereunder. Accordingly, if it should appear to Executive that Employer
has failed to comply with any of its obligations under this Agreement or in the
event that Employer or any other person takes any action to declare this
Agreement void or unenforceable, or institutes any litigation, arbitration or
other legal action designed to deny, or to recover from Executive, the benefits
intended to be provided to Executive hereunder, Employer irrevocably authorizes
Executive from time to time to retain counsel of his choice, at the expense of
Employer as hereafter provided, to represent Executive in connection with the
initiation or defense of any litigation, arbitration or other legal action,
whether by or against Employer or any director, officer, shareholder or other
person affiliated with Employer, in any jurisdiction. Notwithstanding any
existing or prior attorney- client relationship between Employer and such
counsel, Employer irrevocably consents to Executive's entering into an
attorney-client relationship with such counsel, and in that connection Employer
and Executive agree that a confidential relationship shall exist between
Executive and such counsel. Employer shall pay and be solely responsible for
reasonable and necessary attorneys' and related fees and expenses incurred by
Executive as a result of Employer's failure to perform this Agreement or any
provision thereof or as a result of Employer or any person contesting the
validity or enforceability of this Agreement or any provision thereof as
aforesaid, but only if Executive obtains a final legal judgment or settlement in
his favor. All fees and expenses due hereunder shall be paid upon presentation
by Executive to Employer of a statement or statements prepared by such counsel
and containing such information and detail as may be requested by Employer.

death, if earlier.

         3.       Death of Eligible Director. If an Eligible Director dies after
benefits have commenced under paragraph 1 above, but prior to the receipt of 36
monthly payments, monthly payments of $1,000 shall be continued to the
beneficiary designated by the Eligible Director for the duration of the 36 month
