          During the lifetime of the Optionee, only he may exercise the Option

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

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 Thousand (1000) shares (or the minimum installment set forth in Section 3.1,
if a smaller number of shares) and shall be for whole shares only.

4.3.  Manner of Exercise
- ----  ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Secretary or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (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; and

               (i)    Full payment (by cashiers check or wire transfer) for the
     shares with respect to which such Option or portion is exercised; or

               (ii)   With the consent of the Administrator, (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; or

               (iii)  With the consent of the Administrator, a 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 Administrator.  The
     Administrator may also prescribe the form of such note and the security to
     be given for such note.  That 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

 
               (iv)   With the consent of the Administrator, any combination of
     the consideration provided in the foregoing subparagraphs (i) - (iii); and

          (b) A bona fide written representation and agreement, in a form
satisfactory to the Administrator, 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 Administrator 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 Administrator 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 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 if the shares to be issued pursuant to such exercise
have been registered under the Securities Act, and such registration is then
effective in respect of such shares; and

          (c) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; with the consent of the Administrator, (i) shares
of the Company's Common Stock owned by the Optionee duly endorsed for transfer,
or (ii) 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,
valued at fair market value at the date of Option exercise, may be used to make
all or part of such payment; and

          (d) In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

4.4.  Certain Timing Requirements
- ----  ---------------------------

          Shares of the Company's Common Stock issuable to the Optionee upon
exercise of the Option may be used to satisfy the Option price or the tax
withholding consequences of such exercise only (i) during the period beginning
on the third (3rd) business day following the date of release of the quarterly
or annual 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 issuable to the Optionee upon exercise of the Option to pay all or
part of the Option price or the withholding taxes (subject to the approval of
the Administrator) made at least six (6) months prior to the payment of such
Option price or withholding taxes.

shares under any state or federal law or under rulings or regulations of the
Securities and Exchange Commission or of any other governmental regulatory body,
which the Administrator shall, in its absolute discretion, deem necessary or
advisable; and

          (c) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Administrator shall, in its absolute
discretion, determine to be necessary or advisable; and

          (d) The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (e) The lapse of such reasonable period of time following the exercise
of the Option as the Administrator may from time to time establish for reasons
of administrative convenience.

4.6.  Rights as Shareholder
- ----  ---------------------

          The holder of the Option shall not be, nor have any of the rights or
privileges of, a shareholder of the Company in respect of any shares purchasable

- ----  ----------------------------------

          (a) There can be no valid transfer (as hereinafter defined) of any
shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such shares or interests unless such transfer is solely
for cash consideration and is made in compliance with the following provisions:

               (i)    Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares') shall give written notice (by registered or certified
     mail) to the Company.  Such notice shall specify (i) the bona fide intent
     of the record holder of the Offered Shares (hereinafter referred to as the
     "Offeror") to sell or otherwise transfer the Offered Shares to a bona fide
     third-party transferee (ii) the identity of the proposed transferee, (iii)
     the number of Offered Shares to be transferred to the proposed transferee,
     (iv) the cash price offered for the Offered Shares by the proposed
     transferee (the "Offered Price") and (v) the other terms and conditions of
     the proposed transfer.  The date such notice is mailed shall be hereinafter
     referred to as the "notice date" and the record holder of the Offered
     Shares shall be hereinafter referred to as the "Offeror."

               (ii)   For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(iii) of this Section 5.8.  This option shall be
     exercisable by the Company by mailing (by registered or certified mail)
     written notice of exercise to the Offeror prior to the end of said thirty
     (30) days.

               (iii)  The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be (A) if the notice
     date is prior to the date of the Initial Public Offering, the Offered Price
     (as set forth in the notice required under subsection (a)(i) of this
     Section 5.8), and (B) if the notice date is after the date of the Initial
     Public Offering, the fair market value of the Offered Shares on the notice
     date.  The Company's notice of exercise of such option shall be accompanied
     by full payment for the Offered Shares and, upon such payment by the
     Company, the Company shall acquire full right, title and interest to all of
     the Offered Shares.

               (iv)   If, and only if, the option given pursuant to subsection
     (a)(ii) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(i) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the 

 
     expiration of said thirty-day option exercise period, and if such transfer
     has not taken place prior to said ninetieth (90th) day, such transfer may
     not take place without once again complying with subsection (a) of this
     Section 5.8.

          (b) As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the transferee or donee agrees to be bound by the
provisions of this Section 5.8.

          (c) None of the shares of the Company's stock purchased on exercise of
the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been compiled with
in all respects.  The certificates of stock evidencing shares of stock purchased
on exercise of the Option shall bear an appropriate legend referring to the
transfer restrictions imposed by this Section 5.8.
