conjunction with others, arising out of or as a result of Executive's employment
with the Company shall be the sole and absolute property of the Company and the
Affiliates, free of any reserved or other rights of any kind on Executive's
part.  During Executive's employment and, if such Developments were made,
conceived or suggested by Executive during or as a result of Executive's

Affiliates, thereafter, Executive shall promptly make full disclosure of any
such Developments to the Company and, at the Company's cost and expense, do all
acts and things (including, among others, the execution and delivery under oath
of patent and copyright applications and instruments of assignment) deemed by
the Company to be necessary or desirable at any time in order to effect the full
assignment to the Company and the Affiliates of Executive's right and title, if
any, to such Developments.  For purposes of this Agreement, the term

interest which may arise in the performance of the Executive's services

established the following:

     a) The Executive and Company will work together to avoid any conflicts
     relating to his employment with Medco.

     b) The Company will not solicit, nor will the Executive provide to the
     Company, any information confidential or proprietary to Medco and its
     affiliates in the course of the Executive's employment hereunder.

     c) The Company will allow the Executive sufficient business time to satisfy
     his employment obligations to Medco.

breach or threatened breach of any of the covenants set forth in Sections 1.1
through 1.8 will be difficult to determine and will not afford a full and
adequate remedy, and therefore agrees that the Company, in addition to seeking
actual damages in connection therewith, may seek specific enforcement of any
such covenant in any court of competent jurisdiction, including, without

actually vest, not the last date on which all Existing Company Options have
actually vested.

supplemented, canceled or discharged, except by written instrument executed by
the party against whom enforcement is sought.  No failure to exercise, and no
delay in exercising, any right, power or privilege hereunder shall operate as a
waiver thereof.  No waiver of any breach of any provision of this Agreement

               --------                                                   
reference purposes only and shall not affect the meaning or interpretation of

        7.5.   Governing Law; Interpretation.  This Agreement shall be construed
               ----------------------------                                     
in accordance with and governed for all purposes by the laws and public policy

        7.6.   Further Assurances.  Each of the parties agrees to execute,

of the possibility of differing interpretations of law and changes in
circumstances, the parties agree that if any one or more of the provisions of
this Agreement shall be determined by a court of competent jurisdiction to be
invalid, void or unenforceable, the remainder of the provisions of this
Agreement shall, to the extent permitted by law, remain in full force and effect
and shall in no way be affected, impaired or invalidated.  Moreover, if any of
the provisions contained in this Agreement is determined by a court of competent
jurisdiction to be excessively broad as to duration, activity, geographic
application or subject, it shall be construed, by limiting or reducing it to the
extent legally permitted, so as to be enforceable to the extent compatible with
then applicable law.

the unvested portion of the Option.

    material respect which failure is not cured by Optionee within 30 days
    following written notice from the Company detailing such failure;

          (b)  Any willful misconduct by Optionee relating, directly or
    indirectly, to the Company or any of its affiliates, which breach, if
    susceptible to cure, is not cured by Optionee within 30 days following
    written notice from the Company detailing such breach;

          (c)  Any breach by Optionee of any material provision contained in

    metropolitan area.

    2.5.  In the event that Optionee's employment with the Company is terminated
(I) by the Company without Cause (as defined in Section 2.3) or (II) by Optionee
for Cause (as defined in Section 2.4), the Option shall remain outstanding and
continue to vest, and shall otherwise be treated for purposes of this Agreement,
as if Optionee remained in the employ of the Company through the earlier of (a)
the second anniversary of the date of termination or (b) the occurrence of any
circumstance or event that would constitute Cause under Section 2.3 of this
Agreement.

    2.6.  In the event that Optionee's employment with the Company is terminated
(I) by Optionee upon 30 days' written notice to the Company at any time after a
12 month period following the occurrence of the Change of Control (as defined
below) (or such shorter period to the extent the acquiring company does not
request the services of the Optionee for such 12 month

                                       3

period), (II) by the Company because Optionee shall become ill, mentally or
physically disabled, or otherwise incapacitated so as to be unable regularly to
perform the duties of his position for a period in excess of 90 consecutive days
or more than 120 days in any consecutive 12 month period, or (III) due to his
death, the Option shall remain outstanding and continue to vest, and shall
otherwise be treated for the purposes of the terms and conditions thereof, as if
Optionee remained in the employment of the Company through the earlier of (a)
November 6, 2002 and (b) the occurrence of any circumstances or events that
would constitute Cause under such Section 2.3. For purposes of this Section 2.6,
a "Change of Control" shall be deemed to have occurred if:
   -----------------

    (a) both (i) any person, entity or group shall have acquired at least 50% of
    the voting power of the outstanding voting securities of the company
                                                                        
    ("Voting Power"), excluding Martin J. Wygod and his affiliates, and (ii)
    --------------                                                          
    following such acquisition of 50% Voting Power, Martin J. Wygod shall cease
    to hold one or more of the following positions: Chairman of the Board or
    Chief Executive Officer of the Company or a senior executive office of the
    acquirer of 50% Voting Power, in each case with duties and responsibilities
    greater than or substantially equivalent to those prior to such acquisition
    of 50% Voting Power; or

    (b) both (i) a reorganization, merger or consolidation or sale of other
    disposition of all or substantially all of the assets of the Company
                                                                        
    ("Business Combination") shall have occurred and (ii) following such
    ----------------------                                              
    Business Combination, Martin J. Wygod shall cease to be Chairman of the
    Board or Chief Executive Officer of, or to hold a senior executive position
    in, the corporation resulting from such Business Combination, with duties
    and responsibilities greater than or substantially equivalent to those prior
    to such Business Combination; or

    (c) a complete liquidation or dissolution of the Company shall have
    occurred.

    2.7.  Notwithstanding any other provision of this Agreement, the Committee
may determine that the Option shall become exercisable in full or in part,
whether or not it is then exercisable, upon such circumstances or events as the
Committee determines, in its sole discretion, merits special consideration.

    2.8   Notwithstanding anything to the contrary contained herein, in no event
shall the Option be exercisable after the expiration of fifteen years from the
date of this Agreement.

    3.    Method of Exercise of Option.  The Option may be exercised by Optionee
          ----------------------------                                          
(or by Optionee's personal representatives or heirs at law, as provided in
Section 2, but by no other person) as to all or (at Optionee's election) part of
the Shares as to which the Option is then exercisable (that is, vested) under
Section 2 by giving written notice of exercise to the Company at its principal
business office, specifying the number of Shares for which the Option is
exercised, 

                                       4
<PAGE>
 
accompanied by payment in full for such Shares (as determined pursuant to
Section 4) together with any amount required for payroll withholding tax under
all applicable federal, state or local laws or regulations. The failure to
exercise the Option, in whole or in part, as to any vested exercise rights shall
not constitute a waiver of these rights. The Company shall cause certificates
for the Shares so purchased to be delivered to Optionee or Optionee's personal
representatives or heirs at law, at its principal business office, against
payment in full of the Option price for such Shares (as determined pursuant to
Section 4), as soon as practicable following receipt of the notice of exercise
and the applicable purchase price. The Option price shall be paid in United
States dollars in the form of cash, certified check or bank draft, or (if the
Shares of Common Stock of the Company are then publicly traded) in fully paid
Shares of Common Stock of the Company, that have been held by the Optionee for a
period of at least six months (valued for this purpose at their then fair market
value determined by the Committee), consistent with practices permitted by the
Committee or a combination of the two.

    4.    Option Price.  Subject to adjustment as provided in Section 9, the
          ------------                                                      
purchase price of the Shares covered by this Agreement shall be $34.875 per
Share.

    5.    Non-Transferability of Option.  The Option is not assignable or
          -----------------------------                                  
transferable except by will or by the laws of descent and distribution and the
Option may not be exercised other than by the Optionee or, after the death of
the Optionee, by the Optionee's personal representative, heirs or legatees;
provided, however, that the Committee may, subject to such terms and conditions
as the Committee shall specify, permit the transfer of the Option to the
Optionee's family members or to one or more trusts established in whole or in
part for the benefit of one or more of such family members.  Without limiting
the generality of the foregoing, the Option may not be assigned, transferred
(except as permitted in the preceding sentence), pledged or hypothecated in any
way (whether by operation of law or otherwise), and shall not be subject to
levy, attachment or similar process.  Any attempt to assign, transfer, pledge or
hypothecate the Option contrary to the provisions of this Agreement, and any
levy, attachment or similar process upon the Option shall be null and void and
without effect, and the Board or the Committee may, in its discretion, upon the
happening of any such event, terminate the Option as of the date of such event.

    6.    No Rights Prior to Issuance of Shares.  The holder of the Option shall
          -------------------------------------                                 
not have any rights to dividends nor any other rights of a shareholder with
respect to the Shares covered by the Option until the Shares have been issued
(as evidenced by the appropriate entry on the books of the transfer agent of the
Company) following exercise of the Option prior to its termination.

    7.    Restrictions on Exercise and on Common Stock.
          -------------------------------------------- 

    7.1.  The Shares issued upon exercise of the Option shall be issued only to
Optionee or a person permitted to exercise the Option pursuant to Section 2.3.

    7.2.  The Company may require the Optionee to represent to the Company, in
writing, when the Option is exercised, that the Optionee is exercising the
Option for the Optionee's own account for investment only and not with a view to
distribution and that the Optionee will not make any sale, transfer or other
disposition of any Shares purchased except (i) pursuant to a registration
statement filed under the Securities Act of 1933 as amended, which the
Securities and Exchange Commission has declared effective, (ii) pursuant to an
opinion of counsel satisfactory in form and substance to the Company that the
sale, transfer or other disposition may be made without registration, or (iii)
pursuant to a "no action" letter issued to the Optionee by the Securities and
Exchange Commission.  The Company may require each share certificate
representing Shares to bear a legend stating that the Shares evidenced thereby
may not be sold or transferred except in compliance with the Securities Act of
1933, as amended, and the provisions of this Agreement. Notwithstanding anything
contained herein to the contrary, the Option shall not be exercisable at a time
when the exercise thereof may result in the violation of any law or governmental
order or regulation.

    8.    Right to Terminate Employment.  This Agreement does not constitute a
          -----------------------------                                       
contract of, or an implied promise to continue, Optionee's employment or status
with the Company or any subsidiary of the Company; and nothing contained in this
Agreement shall confer upon Optionee the right to continue such employment or
status; nor does this Agreement affect the right of the Company to terminate
Optionee's employment at any time.  Optionee shall have no rights in the
benefits conferred by the Option or in any Shares except to the extent the
Option is exercised while vested and prior to termination.  Termination of the
Option by reason of rightful termination of employment shall give no rise for
any claim for damages by Optionee under this Agreement and shall be without
prejudice to any rights or remedies which the Company or any subsidiary of the
Company may have against Optionee.

    9.    Adjustment.
          ---------- 

    9.1.  In the event of any subdivision (stock split) or consolidation
(reverse split) of the issued Common Stock of the Company, or any other
recapitalization of the Company, or any business combination or other
transaction involving the Company, which shall substantially affect the rights
of holders of Common Stock, the Board or the Committee shall make such
appropriate adjustments to the number of Shares and price per Share covered by
the Option, and any other rights under the Option, as deemed appropriate by the
Board or the Committee, as the case may be (whose good faith determination shall
be absolute and binding upon Optionee), to provide Optionee with a benefit
equivalent to that to which Optionee would have been entitled if such event had
not occurred; provided, however, that if, as a result of such event, the Common
Stock is no longer publicly traded, the Board or the Committee shall make such
appropriate adjustments to the unvested portion of the Option, as deemed
appropriate by the Board or the Committee, as the case may be (whose good faith
determination shall be absolute and binding upon Optionee), to provide Optionee
with a benefit equivalent to that to which Optionee would have been entitled if

                                       6
<PAGE>
 
Optionee would have had the right to exercise any unvested portion of the Option
immediately prior to such event.  The Committee or the Board, as the case may
be, shall provide for appropriate adjustment of the Option in the event of stock
dividends or distributions of assets or securities of other companies owned by
the Company to stockholders relating to Common Stock for which the record date
is prior to the date the Shares purchased by exercise of the Option are issued
or transferred, except that no such adjustment shall be made for cash dividends
or stock dividends of 10% or less (cumulatively, in the aggregate).

    9.2.  In case the Company is merged or consolidated with another
corporation, or in case of a reorganization of the Company, the Board or the
board of directors of any corporation assuming the obligations of the Company
hereunder shall either (i) make appropriate provisions for the protection of any
outstanding portion of the Option by the substitution on an equitable basis of
appropriate securities of the Company, or appropriate securities of the merged,
consolidated, or otherwise reorganized corporation, or the appropriate
adjustment in the option price, or both, or (ii) give written notice to the
Optionee that his Option must be exercised, to the extent then exercisable,
within 60 days of the date of such notice or the Option will terminate, and to
the extent that the Option is not exercised within such 60-day period it shall
terminate and be of no further effect.

    10.   Taxes.  If  the Company shall be required to withhold any amounts by
          -----                                                               
reason of any federal, state or local tax rules or regulations in respect of the
payment of cash or the issuance of Shares pursuant to the exercise of an Option,
the Company shall be entitled to deduct and withhold such amounts from any cash
payments to be made to the Optionee.  In any event, the Optionee shall either
(i) make available to the Company, promptly when requested by the Company,
sufficient funds to meet the requirements of such withholding, or (ii) to the
extent permitted by the Committee, irrevocably authorize the Company to withhold
from the Shares otherwise issuable to the Optionee as a result of such exercise
a number of Shares having a fair market value, as of the date the withholding
tax obligation arises (the "Tax Date") which alone, or when added to funds paid
                            --------                                           
to the Company by the Optionee, equal the amount of the minimum withholding tax
obligation (the "Withholding Election") and the Company shall be entitled to
                 --------------------                                       
take and authorize such steps as it may deem advisable in order to have such
funds made available to the Company out of any funds or property due or to
become due to the Optionee.  An Optionee's Withholding Election may only be made
prior to the Tax Date and may be disapproved by the Committee.  The Committee
may establish such rules and procedures as it may deem necessary or advisable in
connection with the withholding of taxes relating to the exercise of the Option.

    11.   Notices.  Each notice relating to this Agreement shall be in writing
          -------                                                             
and delivered in person or by certified mail to the proper address.  Each notice
to the Company shall be addressed to it at its principal office, attention of
the Chief Financial Officer, with a copy to the Company's General Counsel.  Each
notice to Optionee (or other person or persons then entitled to exercise the
Option) shall be addressed to Optionee (or such other person or persons) at

                                       7
<PAGE>
 
Optionee's most recent address on the books of the Company.  Anyone to whom a
notice may be given under this Agreement may designate a new address by notice
to that effect.  Each notice shall be deemed to have been given on the day it is
received.

Company under this Agreement shall be binding upon Optionee's personal
representatives and heirs at law.

          ----------------                                                 
source of any and all rights which Optionee, and Optionee's personal
representatives or heirs at law, may have in respect of the Option as granted
hereunder.

Agreement.

          The Company desires to provide Optionee with an opportunity to acquire
shares of Common Stock (as defined below) of the Company.  As a result, the
Company has elected to issue to Optionee an option to acquire 250,000 shares of

effective as of October 2, 1996 (the "Date of Grant"), the Company hereby
                                      -------------                      
confirms that Optionee has been granted, subject to the terms of this Agreement
and the terms of the Plan, the right (the "Option") to purchase 250,000 shares

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

employee of the Company for any reason in the case of the vested portion of the
Option (or the date on which a portion of the Option vests pursuant to Sections
2.5 and 2.6) and immediately following such date of termination in the case of
the unvested portion of the Option.

     2.3.   If Optionee's employment is terminated by the Company for Cause (as
defined in this Section 2.3), the Option (both vested and non-vested) shall
expire on the date of termination. For purposes of this section of this
Agreement, the term "Cause" shall mean any of the following:
                     -----                                  

          (a)  A willful failure of Optionee to perform his duties in any
     material respect which failure is not cured by Optionee within 30 days
     following written notice from the Company detailing such failure;

          (b)  Any willful misconduct by Optionee relating, directly or
     indirectly, to the Company or any of its affiliates, which breach, if
     susceptible to cure, is not cured by Optionee within 30 days following
     written notice from the Company detailing such breach;

          (c)  Any breach by Optionee of any material provision contained in
     this Agreement or any employment or consulting agreement between the

shall expire on the date of 

                                       2
<PAGE>
 
termination.  For purposes of this section of this
Agreement, the term "Cause" shall mean any of the following:
                     -----

     Company's headquarters and such headquarters is outside of the New York
     City metropolitan area.

     2.5. In the event that Optionee's employment with the Company is terminated
(I) by the Company without Cause (as defined in Section 2.3) or (II) by Optionee
for Cause (as defined in Section 2.4), the Option shall remain outstanding and
continue to vest, and shall otherwise be treated for purposes of this Agreement,
as if Optionee remained in the employ of the Company through the earlier of (a)
the second anniversary of the date of termination or (b) the occurrence of any
circumstance or event that would constitute Cause under Section 2.3 of this
Agreement.

     2.6. In the event that Optionee's employment with the Company is terminated
(I) by Optionee upon 30 days' written notice to the Company at any time after a
12 month period following the occurrence of the Change of Control (as defined
below) (or such shorter period to the extent the acquiring company does not
request the services of the Optionee for such 12 month period), (II) by the
Company because Optionee shall become ill, mentally or physically disabled, or
otherwise incapacitated so as to be unable regularly to perform the duties of
his position for a period in excess of 90 consecutive days or more than 120 days
in any consecutive 12 month period, or (III) due to his death, the Option shall

purposes of the terms and conditions thereof, as if Optionee remained in the
employment of the Company through the earlier of (a) November 6, 2002 and (b)
the occurrence of any circumstances or events that would constitute Cause under
such Section 2.3.  For purposes of this Section 2.6, a "Change of Control" shall
                                                        -----------------       
be deemed to have occurred if:

          (a) both (i) any person, entity or group shall have acquired at least
     50% of the voting power of the outstanding voting securities of the company
     ("Voting Power"), excluding Martin J. Wygod and his affiliates, and (ii)
       ------------                                                          
     following such acquisition of 50% Voting Power, Martin J. Wygod shall cease
     to hold one or more of the following positions: Chairman of the Board or
     Chief Executive Officer of the Company or a senior executive office of the
     acquirer of 50% Voting Power, in each case with duties and responsibilities
     greater than or substantially equivalent to those prior to such acquisition
     of 50% Voting Power; or

                                       3
<PAGE>
 
          (b) both (i) a reorganization, merger or consolidation or sale of
     other disposition of all or substantially all of the assets of the Company
     ("Business Combination") shall have occurred and (ii) following such
       --------------------                                              
     Business Combination, Martin J. Wygod shall cease to be Chairman of the
     Board or Chief Executive Officer of, or to hold a senior executive position
     in, the corporation resulting from such Business Combination, with duties
     and responsibilities greater than or substantially equivalent to those
     prior to such Business Combination; or

          (c) a complete liquidation or dissolution of the Company shall have
     occurred.

     2.7. Notwithstanding any other provision of this Agreement, the Committee,
the Board or the Designated Officer may determine that the Option shall become
exercisable in full or in part, whether or not it is then exercisable, upon
such circumstances or events as the Committee, the Board or the Designated
Officer determines, in its sole discretion, merits special consideration.

     2.8  Notwithstanding anything to the contrary contained herein, in no event
shall the Option be exercisable after the expiration of fifteen years from the
date of this Agreement.

     3.   Method of Exercise of Option.  The Option may be exercised by Optionee
          ----------------------------                                          
(or by Optionee's personal representatives or heirs at law, as provided in
Section 2, but by no other person) as to all or (at Optionee's election) part of
the Shares as to which the Option is then exercisable (that is, vested) under
Section 2 by giving written notice of exercise to the Company at its principal
business office, specifying the number of Shares for which the Option is
exercised, accompanied by payment in full for such Shares (as determined
pursuant to Section 4) together with any amount required for payroll withholding
tax under all applicable federal, state or local laws or regulations.  The
failure to exercise the Option, in whole or in part, as to any vested exercise
rights shall not constitute a waiver of these rights.  The Company shall cause
certificates for the Shares so purchased to be delivered to Optionee or
Optionee's personal representatives or heirs at law, at its principal business
office, against payment in full of the Option price for such Shares (as
determined pursuant to Section 4), as soon as practicable following receipt of
the notice of exercise and the applicable purchase price.  The Option price
shall be paid in United States dollars in the form of cash, certified check or
bank draft, or (if the Shares of Common Stock of the Company are then publicly
traded) in fully paid Shares of Common Stock of the Company that have been held
by the Optionee for a period of at least six months (valued for this purpose at
their then fair market value determined by the Committee, the Board or the
Designated Officer), consistent with practices permitted by the Committee, the
Board or the Designated Officer, or a combination of the two.

     4.   Option Price.  Subject to adjustment as provided in Sections 7.6 and 9
          ------------                                                          
of the Plan, the purchase price of the Shares covered by this Agreement shall be

     5.   Non-Transferability of Option.  The Option is not assignable or
          -----------------------------                                  
transferable except by will or by the laws of descent and distribution and the
Option may not be exercised other than by the Optionee or, after the death of
the Optionee, by the Optionee's personal representative, heirs or legatees.
Without limiting the generality of the foregoing, the Option may not be
assigned, transferred (except as permitted in the preceding sentence), pledged
or hypothecated in any way (whether by operation of law or otherwise), and shall
not be subject to levy, attachment or similar process.  Any attempt to assign,
transfer, pledge or hypothecate the Option contrary to the provisions of this
Agreement, and any levy, attachment or similar process upon the Option shall be
null and void and without effect, and the Board, the Committee or the Designated
Officer may, in its discretion, upon the happening of any such event, terminate
the Option as of the date of such event.

     6.   No Rights Prior to Issuance of Shares.  The holder of the Option shall
          -------------------------------------                                 
not have any rights to dividends nor any other rights of a shareholder with
respect to the Shares covered by the Option until the Shares have been issued
(as evidenced by the appropriate entry on the books of the transfer agent of the
Company) following exercise of the Option prior to its termination.

     7.   Restrictions on Exercise and on Common Stock.
          -------------------------------------------- 

     7.1. The Shares issued upon exercise of the Option shall be issued only to
Optionee or a person permitted to exercise the Option pursuant to Section 2.3.

     7.2. The Company may require the Optionee to represent to the Company, in
writing, when the Option is exercised, that the Optionee is exercising the
Option for the Optionee's own account for investment only and not with a view to
distribution and that the Optionee will not make any sale, transfer or other
disposition of any Shares purchased except (i) pursuant to a registration
statement filed under the Securities Act of 1933 as amended, which the
Securities and Exchange Commission has declared effective, (ii) pursuant to an
opinion of counsel satisfactory in form and substance to the Company that the
sale, transfer or other disposition may be made without registration, or (iii)
pursuant to a "no action" letter issued to the Optionee by the Securities and
Exchange Commission.  The Company may require each share certificate
representing Shares to bear a legend stating that the Shares evidenced thereby
may not be sold or transferred except in compliance with the Securities Act of
1933, as amended, and the provisions of this Agreement. Notwithstanding anything
contained herein to the contrary, the Option shall not be exercisable at a time
when the exercise thereof may result in the violation of any law or governmental
order or regulation.

     8.   Right to Terminate Employment.  This Agreement does not constitute a
          -----------------------------                                       
contract of, or an implied promise to continue, Optionee's employment or status
with the Company or any subsidiary of the Company; and nothing contained in this
Agreement shall confer upon Optionee the right to continue such employment or
status; nor does this Agreement affect the right of the 

                                       5
<PAGE>
 
Company to terminate Optionee's employment at any time. Optionee shall have no
rights in the benefits conferred by the Option or in any Shares except to the
extent the Option is exercised while vested and prior to termination.
Termination of the Option by reason of rightful termination of employment shall
give no rise for any claim for damages by Optionee under this Agreement and
shall be without prejudice to any rights or remedies which the Company or any
subsidiary of the Company may have against Optionee.

     9.   Taxes.  If  the Company shall be required to withhold any amounts by
          -----                                                               
reason of any federal, state or local tax rules or regulations in respect of the
payment of cash or the issuance of Shares pursuant to the exercise of an Option,
the Company shall be entitled to deduct and withhold such amounts from any cash
payments to be made to the Optionee.  In any event, the Optionee shall either
(i) make available to the Company, promptly when requested by the Company,
sufficient funds to meet the requirements of such withholding, or (ii) to the
extent permitted by the Committee, the Board or the Designated Officer,
irrevocably authorize the Company to withhold from the Shares otherwise issuable
to the Optionee as a result of such exercise a number of Shares having a fair
market value, as of the date the withholding tax obligation arises (the "Tax
                                                                         ---
Date") which alone, or when added to funds paid to the Company by the Optionee,
----                                                                           
equal the amount of the minimum withholding tax obligation (the "Withholding
                                                                 -----------
Election") and the Company shall be entitled to take and authorize such steps as
--------                                                                        
it may deem advisable in order to have such funds made available to the Company
out of any funds or property due or to become due to the Optionee.  An
Optionee's Withholding Election may only be made prior to the Tax Date and may
be disapproved by the Committee, the Board or the Designated Officer.  The
Committee, the Board or the Designated Officer may establish such rules and
procedures as it may deem necessary or advisable in connection with the
withholding of taxes relating to the exercise of the Option.

     10.  Notices.  Each notice relating to this Agreement shall be in writing

and delivered in person or by certified mail to the proper address.  Each notice
to the Company shall be addressed to it at its principal office, attention of
the Chief Financial Officer, with a copy to the Company's General Counsel.  Each
notice to Optionee (or other person or persons then entitled to exercise the
Option) shall be addressed to Optionee (or such other person or persons) at
Optionee's most recent address on the books of the Company.  Anyone to whom a
notice may be given under this Agreement may designate a new address by notice
to that effect.  Each notice shall be deemed to have been given on the day it is
received.

     11.  Benefits of Agreement.  This Agreement shall inure to the benefit of
