Form of Stock Option Grant. Each such stock option ("Option") shall be in writing (an "Option Agreement") and shall specify (i) the name of the recipient of the Option (the "Optionee"), (ii) the number of shares of Common Stock subject to such Option, and (iii) the terms applicable to the exercise of such Option, including the exercise price, any restrictions applicable to such exercise and the expiration date (the "Expiration Date") for such exercise. 2. Time and Manner of Exercise. 2.1. Exercise of Option. (a) Except as otherwise provided herein, an Option shall become exercisable as described under the caption "When Exercisable" in the Option Agreement. (b) If an Optionee's employment by the Company terminates by reason of Retirement, death or Disability, then on the date of such Retirement, death or Disability, such Optionee's Option shall, notwithstanding Section 2.1(a) hereof, become exercisable as to all of the shares of Common Stock remaining subject to such Option and may (1) in the cases of Retirement or Disability, be exercised by such Optionee or his or her Legal Representative or Permitted Transferees, as the case may be, until the Expiration Date or (2) in the case of death, be exercised by such Optionee's Legal Representative or Permitted Transferees, as the case may be, until 11:59 p.m. (Chicago time) on the third anniversary of the date of death; provided, however, that in any case such exercisability is conditioned upon such Optionee's or his or her Legal Representative's or Permitted Transferees', as the case may be, continued "acceptable conduct," as determined by the Committee in its sole discretion. For purposes of the foregoing, "acceptable conduct" shall mean, without limitation, refraining from engaging in activities which (i) are competitive to the business of the Company or its subsidiaries, (ii) promote or assist competitors of the Company or its subsidiaries, or (iii) reflect negatively on the Company, its subsidiaries or any of their directors, officers, employees or agents. (c) If an Optionee's employment by the Company terminates either for cause or by voluntary action of such Optionee (other than Retirement), such Optionee's Option shall expire on the effective date of such termination of employment and shall not thereafter be exercisable. (d) If an Optionee's employment by the Company terminates for any reason other than Retirement, Disability, death or as specified in Section 2.1(c) hereof, such Optionee's Option shall be exercisable only to the extent it is exercisable on the effective date of such termination of employment and may thereafter be exercised by such Optionee or his or her Legal Representative until and including the earlier to occur of (i) the date which is three months after the effective date of such termination of employment and (ii) the Expiration Date. 2.2. Method of Exercise. Subject to the limitations set forth in the Option Agreement and these General Provisions, an Option may be exercised by the Optionee: (a) by giving written notice to the Company specifying the number of whole shares of Common Stock to be purchased and accompanied by payment therefor in full (or arrangement made for such payment to the Company's satisfaction) (1) in cash, (2) by delivery of previously owned whole shares of Common Stock (which such Optionee has held for at least six months prior to the delivery of such shares or which such Optionee purchased on the open market and for which such Optionee has good title, free and clear of all liens and encumbrances) having an aggregate Fair Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable pursuant to such Option by reason of such exercise, (3) in cash by a broker-dealer acceptable to the Company to whom such Optionee has submitted an irrevocable notice of exercise or (4) a combination of (1) and (2), and (b) by executing such documents as the Company may reasonably request. The Company shall have sole discretion to disapprove of an election pursuant to any of subclauses (2) through (4) of clause (a) of this Section 2.2. Any fraction of a share of Common Stock which would be required to pay such purchase price shall be disregarded and the remaining amount due shall be paid in cash by the Optionee. No certificate representing a share of Common Stock shall be delivered until the full purchase price therefor has been paid. -2- 2.3. Termination of Option. (a) In no event may an Option be exercised after it terminates as set forth in this Section 2.3. An Option shall terminate, to the extent not exercised pursuant to Section 2.2 or earlier terminated pursuant to Section 2.1, on the Expiration Date stated in the Option Agreement. (b) In the event that rights to purchase all or a portion of the shares of Common Stock subject to an Option expire or are exercised, cancelled or forfeited, the Optionee shall, upon the Company's request, promptly return the related Option Agreement to the Company for full or partial cancellation, as the case may be. Such cancellation shall be effective regardless of whether the Optionee returns said Option Agreement. If the Optionee continues to have rights to purchase shares of Common Stock under said Option Agreement, the Company shall, within 10 days of the Optionee's delivery of said Option Agreement to the Company, either (i) mark said Option Agreement to indicate the extent to which said Option has expired or been exercised, cancelled or forfeited or (ii) issue to the Optionee a substitute option agreement applicable to such rights, which agreement shall otherwise be substantially similar to said Option Agreement in form and substance. 3. Additional Terms and Conditions of Options. 3.1. Nontransferability of Options. Except as may otherwise be permitted by the Plan or authorized in accordance with the terms of the Plan, an Option may not be transferred by the Optionee other than by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing sentence, during the Optionee's lifetime such Optionee's Option is exercisable only by the Optionee or his or her Legal Representative. Except to the extent permitted by the foregoing, an Option may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt so to sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of an Option, such Option and all rights thereunder shall immediately become null and void. 3.2. Withholding Taxes. (a) As a condition precedent to the delivery of shares of Common Stock upon exercise of an Option, the Optionee shall, upon request by the Company, pay to the Company in addition to the purchase price of the shares, such amount of cash as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the "Required Tax Payments") with respect to such exercise of such Option. If the Optionee shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to the Optionee. -3- (b) The Optionee may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (1) a cash payment to the Company pursuant to Section 3.2(a), (2) delivery to the Company of previously owned whole shares of Common Stock (which the Optionee has held for at least six months prior to the delivery of such shares or which the Optionee purchased on the open market and for which the Optionee has good title, free and clear of all liens and encumbrances) having an aggregate Fair Market Value, determined as of the date the obligation to withhold or pay taxes first arises in connection with such Optionee's Option (the "Tax Date"), equal to the Required Tax Payments, (3) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered to the Optionee upon exercise of such Option having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments, (4) a cash payment by a broker-dealer acceptable to the Company to whom the Optionee has submitted an irrevocable notice of exercise or (5) any combination of (1), (2) and (3). The Company shall have sole discretion to disapprove of an election pursuant to any of clauses (2) through (5). Shares of Common Stock to be delivered or withheld may not have an aggregate Fair Market Value in excess of the minimum amount of the Required Tax Payments. Any fraction of a share of Common Stock which would be required to satisfy any such obligation shall be disregarded and the remaining amount due shall be paid in cash by the Optionee. No certificate representing a share of Common Stock shall be delivered until the Required Tax Payments have been satisfied in full. (c) Unless the Committee otherwise determines, if an Optionee is subject to Section 16 of the Exchange Act, the following provisions shall apply to such Optionee's election to deliver to the Company whole shares of Common Stock or to authorize the Company to withhold whole shares of Common Stock purchasable upon exercise of such Optionee's Option in payment of all or a portion of such Optionee's tax liability in connection with such exercise: (1) Such Optionee may deliver to the Company previously owned whole shares of Common Stock in accordance with Section 3.2(b), if such delivery is in connection with the delivery of shares of Common Stock in payment of the exercise price of such Optionee's Option. (2) Such Optionee may authorize the Company to withhold whole shares of Common Stock purchasable upon exercise of such Optionee's Option in accordance with Section 3.2(b); provided that the following provisions shall apply to such election: (i) such election may apply only to such Option or any or all other options held by such Optionee, shall be filed with the Secretary at least six months prior to the exercise date of such Option and may not take effect -4- during the six-month period beginning on the Grant Date (as specified in the Option Agreement) of such Option (other than in the event of such Optionee's death) or (ii) such election (A) shall be subject to approval by the Committee, (B) may not take effect during the six-month period beginning on the Grant Date (as specified in the Option Agreement) of such Option (other than in the event of such Optionee's death), (C) must be filed with the Secretary during (or must be filed with the Secretary in advance of, but take effect during) the ten business day period beginning on the third business day following the date of release of the Company's quarterly or annual summary statements of sales and earnings and (D) the exercise of such Option must occur during such ten business day period. Unless the Committee otherwise determines, any election pursuant to clause (i) may be revoked or changed only if such revocation or change is made at least six months prior to the exercise of the Option. Any election made pursuant to clause (ii) may be revoked or changed prior to the exercise of the Option during the ten business day period. 3.3. Adjustment. The number and class of securities subject to an Option and the purchase price per security shall be subject to adjustment as provided in Section 4.2 of the Plan. If any such adjustment would result in a fractional security being subject to such Option, the Company shall pay the Optionee, in connection with the first exercise of such Option, in whole or in part, occurring after such adjustment, an amount in cash determined by multiplying (i) the fraction of such security (rounded to the nearest hundredth) by (ii) the excess, if any, of (A) the Fair Market Value on the exercise date over (B) the exercise price per share of such Option. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive. 3.4. Compliance with Applicable Law. Each Option is subject to the condition that if the listing, registration or qualification of the shares subject to such Option upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the purchase or delivery of shares hereunder, such Option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. 3.5. Delivery of Certificates. Upon the exercise of an Option, in whole or in part, the Company shall credit to a book-entry or other electronic account maintained for the Optionee, or deliver or cause to be delivered one or more certificates -5- representing, the number of shares purchased against full payment therefor. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 3.2. 3.6. Rights as a Stockholder. An Optionee shall not be entitled to any privileges of ownership with respect to shares of Common Stock subject to an Option unless and until purchased and credited to an account maintained for such Optionee or delivered to such Optionee upon the exercise of such Option, in whole or in part, and such Optionee becomes a stockholder of record with respect to such shares; and such Optionee shall not be considered a stockholder of the Company with respect to any such shares not so purchased and credited or delivered. 3.7. Company to Reserve Shares. The Company shall at all times prior to the expiration or termination of an Option reserve and keep available, either in its treasury or out of its authorized but unissued shares of Common Stock, the full number of shares subject to such Option from time to time. 3.8. Agreement Subject to the Plan. Each Option Agreement, and the Option thereby granted, are subject to the provisions of the Plan, including, without limitation, Sections 5.1 and 13.2 of the Plan, and shall be interpreted in accordance therewith. 4. Change in Control. (a) Notwithstanding any provision in the Plan or any Option Agreement, in the event of a Change in Control, all outstanding Options shall immediately become exercisable in full. (b) "Change in Control" shall mean: (1) the acquisition by any individual, entity or group (a "Person"), including any "person" within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act, of beneficial ownership within the meaning of Rule 13d-3 promulgated under the Exchange Act, of 20% or more of either (i) the then outstanding shares of Common Stock (the "Outstanding Company Common Stock") or (ii) the combined voting power of the then outstanding securities of the Company entitled to vote generally in the election of directors (the "Outstanding Company Voting Securities");

provided further, that for purposes of clause (B), if any Person (other than the Company or any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company) shall become the beneficial owner of 20% or more of the Outstanding Company Common Stock or 20% or more of the Outstanding Company Voting Securities by reason of an acquisition by the Company, and such Person shall, after such acquisition by the Company, become the beneficial owner of any additional shares of the Outstanding Company Common Stock or any additional Outstanding Company Voting Securities (other than pursuant to any dividend reinvestment plan or arrangement maintained by the Company) and such beneficial ownership is publicly announced, such additional beneficial ownership shall constitute a Change in Control; (2) individuals who, as of the date hereof, constitute the Board of Directors (the "Incumbent Board") cease for any reason to constitute at least a majority of such Board; provided that any individual who becomes a director of the Company subsequent to the date hereof whose election, or nomination for election by the Company's stockholders, was approved by the vote of at least a majority of the directors then comprising the Incumbent Board shall be deemed a member of the Incumbent Board;
