     Section 3.4 Manner of Exercise. The Option may be exercised, in whole or in
     ------------------------------
part, by delivering written notice to the Committee in such form as the
Committee may require from time to time.  Such notice shall specify the number
of shares of Stock subject to the Option as to which the Option is being
exercised, and shall be accompanied by full payment of the Option Price of the
shares of Stock as to which the Option is being exercised.  Payment of the
Option Price may be made either in cash or shares of Stock (including shares of
Stock acquired upon the exercise of an option) having a total Fair Market Value
on the Exercise Date equal to the Option Price multiplied by the number of
shares of Stock as to which the Option is being exercised.  The Option may be
exercised only in multiples of whole shares and no partial shares shall be
issued.  The minimum number of shares of Stock for which the Option may be
exercised shall be the lesser of one hundred (100) shares or the entire number
of shares for which the Option is exercisable on the Exercise Date.  If, as of
the fourth Anniversary Date, the total number of shares as to which the Option
is exercisable includes a partial share, the Option for such partial share,
whether or not previously

                                       7
<PAGE>

designated by the Committee as an Incentive Stock Option, shall be deemed to be
a non-Incentive Stock Option.  On the first date, on or after the fourth
Anniversary Date, that the Fair Market Value of a share of Stock equals or
exceeds the Option Price, Grantee shall be deemed to have simultaneously
exercised the Option for such partial share and to have sold same to MBC for
such Fair Market Value.  MBC shall remit to Grantee, in payment of the purchase
price of such partial share, the excess, if any, of the Fair Market Value of
such partial share over the Option Price.

     Section 3.5 Issuance of Shares and Payment of Cash upon Exercise. Upon
     ----------------------------------------------------------------
exercise of the Option, in whole or in part, in accordance with the terms of the
Agreement, and upon payment of the Option Price for the shares of Stock as to
which the Option is exercised, MBC shall issue to Grantee the number of shares
of Stock so paid for, in the form of fully paid and non-assessable Stock.

     Section 3.6 Loan or Guaranty. Solely at the discretion of the Committee,
     ----------------------------
and upon Grantee's written request, MBC may, but shall not be required to,
assist Grantee in the exercise of the Option by making a loan to Grantee or by
guaranteeing a third-party loan to Grantee. Such a loan or guaranty shall be
conditioned upon prior receipt by the Committee of satisfactory assurances of
Grantee's net worth and repayment ability. Subject to Regulation U of the
Federal Reserve Board, any such loan or guaranty may be in an amount up to one
hundred percent (100%) of the Option Price of the shares of Stock as to which
the Option is being exercised. All loans shall bear interest at a rate
determined by the Committee based upon loans of similar maturity, but in no
event shall the interest rate be less than the rate necessary to avoid the
imputation of interest or original issue discount under the provisions of the
Code. All other terms of any loan or guaranty (including terms of repayment)
shall be established by the

                                       8
<PAGE>

Committee, subject to Regulation U of the Federal Reserve Board and all other
applicable federal and state laws and regulations.

               ---------------------------------
occurrence of Grantee's Retirement on or after Grantee's Normal Retirement Date
all or a portion of the Option has not become exercisable solely because one (1)
or more of the first four (4) Anniversary Dates have not occurred (hereinafter
referred to as the "Remaining Portion"), then such Remaining Portion shall
become exercisable, if at all, on the later of the occurrence of Grantee's
Retirement or March 14 of the calendar year in which such retirement occurs. The
Remaining Portion shall not include any portion of the Option that has
terminated pursuant to the provisions of Sections 3.1, 3.2, 3.3, 4.1, 4.2 or 4.3
