as it, in its absolute discretion, deems appropriate in connection with such
acceleration of exercisability, including, but not by way of limitation,
provisions to ensure that any such acceleration and resulting exercise shall be
conditioned upon the consummation of the contemplated corporate transaction.

Section 4.1 - Person Eligible to Exercise

empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2 - Partial Exercise
- -----------   ----------------

     Any exercisable portion of the Option or the entire Option, if then wholly
exercisable, may be exercised in whole or in part at any time prior to the time
when the Option or portion thereof becomes unexercisable under Section 3.3;
provided, however, that each partial exercise shall be for not less than one
hundred (100) shares (or the minimum installment set forth in Section 3.1, if a
smaller number of shares) and shall be for whole shares only.

Section 4.3 - Manner of Exercise

     The Option, or any exercisable portion thereof, may be exercised solely by

                                       7

 
     (a) Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Committee or the Board;

     (b)  (i)  Full payment (in cash) for the shares with respect to which such
Option or portion is exercised;

     (ii) With the consent of the Board, payment delayed for up to thirty (30)
days from the date the Option, or portion thereof, is exercised;

     (iii)  With the consent of the Board, (A) shares of the Company's Common
Stock owned by the Optionee duly endorsed for transfer to the Company or (B)
subject to the timing requirements of Section 4.4, shares of the Company's
Common Stock issuable to the Optionee upon exercise of the Option, with a Fair
Market Value on the date of Option exercise equal to the aggregate purchase
price of the shares with respect to which such Option or portion is exercised;

     (iv) With the consent of the Board, property of any kind which constitutes
good and valuable consideration;

     (v) With the consent of the Board, a full recourse promissory note bearing
interest (at no less than such rate as shall then preclude the imputation of
interest under the Code or successor provision) and payable upon such terms as
may be prescribed by the Committee or the Board.  The Committee may also
prescribe the form of such note and the security to be given for such note.  The
Option may not be exercised, however, by delivery of a promissory note or by a
loan from the Company when or where such loan or other extension of credit is
prohibited by law; or

     (vi) With the consent of the Board, any combination of the consideration
provided in the foregoing subparagraphs (iii), (iv) and (v);

     (c) A bona fide written representation and agreement, in a form
satisfactory to the Committee or the Board, signed by the Optionee or other
person then entitled to exercise such Option or portion, stating that the shares
of stock are being acquired for his own account, for investment and without any
present intention of distributing or reselling said shares or any of them except
as may be permitted under the Securities Act and then applicable rules and
regulations thereunder, and that the Optionee or other person then entitled to
exercise such Option or portion will indemnify the Company against and hold it
free and harmless from any loss, damage, expense or liability resulting to the
Company if any sale or distribution of the shares by such person is contrary to
the representation and agreement referred to above.  The Committee may, in its
absolute discretion, take whatever additional actions it deems appropriate to
insure the observance and performance of such representation and agreement and
to effect compliance with the Securities Act and any other federal or state
securities laws or regulations.  Without limiting the generality of the
foregoing, the Committee may require an opinion of counsel acceptable to it to
the effect that any subsequent transfer of shares acquired on an Option exercise
does not violate the

                                       8

 
Securities Act, and may issue stop-transfer orders covering such shares.  
Share certificates evidencing stock issued on exercise of this Option shall 
bear an appropriate legend referring to the provisions of this subsection (c) 
and the agreements herein.  The written representation and agreement referred 
to in the first sentence of this subsection (c) shall, however, not be required

the Securities Act, and such registration is then effective in respect of 
such shares;

amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; with the consent of the Board, (i) shares of the

summary statement of sales and earnings of the Company and ending on the twelfth
(12th) business day following such date or (ii) pursuant to an irrevocable
written election by the Optionee to use shares of the Company's Common Stock

required to withhold upon exercise of the Option; and

the Option as the Committee or Board may from time to time establish for reasons
of administrative convenience.
