                     II.  BONUS STOCK AWARDS



2.1  Bonus Stock Awards.  Effective on the Closing Date, the

Company hereby grants Bonus Stock Awards to the eligible persons

whose names are listed on Schedule A hereto.  Such grant shall be

evidenced by a notice to such effect sent by the Company to each

such person as soon as practicable following effectiveness of

this Plan.



2.2  Terms of Bonus Stock Awards.  Bonus Stock Awards shall be

subject to the following terms and conditions.



     (a)  Number of Shares and Other Terms.  The number of shares

of Common Stock subject to a Bonus Stock Award granted pursuant

to this Plan to an employee shall be the number of such shares

set forth opposite the name of such employee on Schedule A

hereto.



     (b)  Vesting and Forfeiture.  One-half of the number of

shares of Common Stock subject to a Bonus Stock Award shall vest

and be payable on the first anniversary of the Closing Date and

the other half of such number shall vest and be payable on the

second anniversary of the Closing Date, in each case (subject to

Section 2.3(b)) if the holder of such award remains continuously

in the employment of the Company or a Subsidiary until such

anniversary date of the Closing Date.  Such holder shall forfeit

the unvested portion of any such shares if such holder does not







remain continuously in the employment of the Company as specified

above, except as otherwise provided in Section 2.3(b).



     (c)  Share Certificates.  Upon the vesting of a portion of a

Bonus Stock Award pursuant to Sections 2.2(b) or 2.3(b), in each

case subject to the Company's right to require payment of any

taxes in accordance with Section 3.2, a certificate or

certificates evidencing ownership of the requisite number of

shares of Common Stock shall be delivered to and in the name of

the holder of such award.  Notwithstanding the foregoing, in lieu

of the delivery of shares representing all or a portion of the

vested portion of a Bonus Stock Award, the Committee may, in its

sole discretion, deliver to the holder cash in an amount equal to

the Fair Market Value on the date such shares become vested of

the vested portion of such award less any applicable withholding

as required by Section 3.2.




2.3  Termination of Employment.  (a)  Terminations Resulting in

Forfeiture.  If (i) the employment with the Company of the holder

of a Bonus Stock Award is terminated by the Company by reason of

Cause, (ii) such employment terminates by reason of the holder's

Disability, or death, or (iii) a holder voluntarily terminates

his employment with the Company for any reason other than

Constructive Discharge, the portion of such award which is not

then vested pursuant to Section 2.2(b) shall be forfeited by such

holder and such portion shall be cancelled by the Company.









     (b)  Other Termination.  If the Company terminates the

employment of the holder of a Bonus Stock Award for any reason

other than Cause or Disability, or if a holder of a Bonus Stock

Award voluntarily terminates his employment with the Company as a

result of a Constructive Discharge, the portion of such award

which is not otherwise vested shall vest without regard to such

termination, and be payable within 30 days of such termination,

in accordance with Section 2.2(c).



2.4  Registration.  The Company will use its best commercial

efforts to cause the shares of Common Stock subject to Bonus

Stock Awards to be registered on Form S-8 under the Securities

Act of 1933, as amended, on or before the first anniversary of

the Closing Date.  No such registration shall be required to the

extent the Company determines, based on the advice of counsel,

that such registration is not required for a holder of a Bonus

Stock Award to transfer vested shares of Common Stock issued to

such holder hereunder free of the transfer restrictions of the

Securities Act of 1933, as amended.



                          III.  GENERAL



3.1  Amendments.  The Board may amend this Plan as it shall deem

advisable, provided, however, that no amendment shall be made if

such amendment would increase or decrease the maximum number of

shares of Common Stock available under this Plan (subject to







Section 3.3).  No amendment may impair the rights of a holder of

an outstanding award whether vested or unvested without the

consent of such holder.



3.2  Tax Withholding.  The Company shall have the right to

require, prior to the issuance or delivery of any shares of

Common Stock or the making of any other payment pursuant to an

award made hereunder, payment by the holder of such award of any

Federal, state, local or other taxes which may be required to be

withheld or paid in connection with such award.  The Committee

may allow shares of Common Stock to be delivered or withheld

having an aggregate Fair Market Value not in excess of the

minimum amount required to be withheld, and in such event, any

fraction of a share of Common Stock which would be required to

satisfy such an obligation shall be disregarded and the remaining

amount due shall be paid in cash by the holder.



3.3  Adjustment.  In the event of any stock split, stock

dividend, recapitalization, reorganization, merger,

consolidation, combination, exchange of shares, liquidation,

spin-off or other similar change in capitalization or event, or

any distribution to holders of Common Stock other than a regular

cash dividend, the number and class of securities available under

this Plan, the number and class of securities subject to each

outstanding Bonus Stock Award, and/or the asset issuable or

payable upon the vesting thereof shall be adjusted or modified

accordingly, as determined by the Committee.  The decision of the







Committee regarding any such adjustment or modification shall be

final, binding and conclusive.  If any such adjustment or

modification would result in a fractional security being subject

to an award under this Plan, the Company shall pay the holder of

such award, in connection with the first vesting of such award,

in whole or in part, occurring after such adjustment or

modification, an amount in cash determined by multiplying (i) the

fraction of such security (rounded to the nearest hundredth) by

(ii) the Fair Market Value on the vesting date.



3.4  No Assignment.  It is a condition of this Plan, and the

rights of all holders of Bonus Stock Awards shall be subject

thereto, that no right or interest of any such holder shall be

assignable or transferable in whole or in part, either directly

or by operation of law or otherwise, including, but not by way of

limitation, execution, levy, garnishment, attachment, pledge or

bankruptcy, and no right or interest of any such holder under

this Plan shall be liable for, or subject to, any obligation of

any such holder, including claims for alimony or the support of

any spouse.



3.5  No Right of Employment.  Neither this Plan nor any award

made hereunder shall confer upon any person any right to

continued employment by the Company, any Subsidiary or any

affiliate of the Company or affect in any manner the right of the

Company, any Subsidiary or any affiliate of the Company to









terminate the employment of any person at any time without

liability hereunder.



3.6  Rights as Stockholder.  No person shall have any right as a

stockholder of the Company with respect to any shares of Common

Stock or other equity security of the Company which is subject to

an award hereunder unless and until such person becomes a

stockholder of record with respect to such shares of Common Stock

or equity security.  The Company's obligation to deliver shares

of Common Stock pursuant to this Plan shall be unfunded, and the

Company shall not be obligated to set aside any of its assets for

the purpose of satisfying its obligations hereunder.  The claims

of holders of Bonus Stock Awards shall be solely those of an

unsecured creditor of the Company.



3.7  Governing Law.  The corporate law of the State of Delaware

shall govern all issues concerning the relative rights of the

Company and the holders of Bonus Stock Awards with respect to

this Plan, the Bonus Stock Awards and Bonus Stock issuable under

the Plan.  The law of the State of Illinois, except its law with

respect to choice of law, shall be controlling in all other

matters relating to the Plan.



3.8  Effective Date.  This Plan shall become effective on the

Closing Date.
