Administration The Plan is administered by the Committee. In addition to any other powers set forth in this Plan, the Committee has the following powers: (a) to construe and interpret the Plan; (b) to establish, amend and rescind appropriate rules and regulations relating to the Plan; (c) subject to the express provisions of the Plan, to select the individuals who will receive Awards, the times when they will receive them, the number of Options, Restricted Stock, Phantom Stock and/or SARs to be subject to each Award, the vesting schedule and the Option Price, payment terms, payment method, and expiration date applicable to each Award; (d) to contest on behalf of the Company or Participants, at the expense of the Company, any ruling or decision on any matter relating to the Plan or to any Awards; (e) generally, to administer the Plan, and to take all such steps and make all such determinations in connection with the Plan and the Awards granted thereunder as it may deem necessary or advisable; (f) to determine the form in which payment of a SAR or a Phantom Stock Award granted hereunder will be made (i.e., cash, Common Stock or a combination thereof) or to approve a Participant's election to receive cash in whole or in part in settlement of the SAR or Phantom Stock Award; and (g) to determine the form in which tax withholding under Section 16 of this Plan will be made (i.e., cash, Common Stock or a combination thereof). 5. Eligible Employees Subject to the provisions of the Plan, the Committee shall from time to time select those key employees of the Company and any subsidiary or affiliate of the Company who shall be designated as Participants and the number, if any, of ISOs, SARs, Restricted Stock, Phantom Stock and NSOs, or any combination thereof, to be awarded to each such Participant; provided, however, that no ISOs, or SARs granted with respect to ISOs, shall be awarded under the Plan after the expiration of the period of ten years from the date this Plan is adopted by the Board. 6. Terms and Conditions of Incentive Stock Options Each ISO agreement, in such form as is approved by the Committee, shall be subject to the following express terms and conditions and to such other terms and conditions, not inconsistent with the Plan, as the Committee may deem appropriate: (a) Option Period. Each ISO will expire as of the earliest of: (i) the date on which it is forfeited under the provisions of Section 12; (ii) ten years (or five years as specified in paragraph (d) below) from the Award Date; (iii) three (3) months after the Participant's termination of employment with the Company and its parent and subsidiaries for any reason other than death; (iv) twelve (12) months after the Participant's death; or (v) any other date (within the limits of the Code) specified by the Committee when the ISO is granted. (b) Option Price. Subject to the provisions of paragraph (d) below, the Option Price shall be determined by the Committee at the time an ISO is granted, and shall not be less than the Fair Market Value of the Common Stock on the Award Date. (c) Other Option Provisions. The form of ISO authorized by the Plan may contain such other provisions as the Committee may, from time to time, determine; provided, however, that such other provisions may not be inconsistent with any requirements imposed on incentive stock options under Code Section 422 and related Treasury regulations. (d) Awards to Certain Stockholders. Notwithstanding paragraphs (a) and (b) above, if an ISO is granted to a Participant who, immediately before the grant of the ISO, owns stock representing more than 10 percent of the total combined voting power of all classes of stock of the Company or its parent or subsidiary corporations, the exercise period specified in the option agreement for which the ISO thereunder is granted shall not exceed five years from the Award Date, and the Option Price shall be at least 110 percent of the Fair Market Value (as of the Award Date) of the stock subject to the ISO. 7. Terms and Conditions of Nonqualified Stock Options Each NSO agreement, in such form as is approved by the Committee, shall be subject to the following express terms and conditions and to such other terms and conditions, not inconsistent with the Plan, as the Committee may deem appropriate: (a) Option Period. Each NSO will expire as of the earliest of: (i) the date on which it is forfeited under the provisions of Section 12; (ii) three (3) months after the Participant's termination of employment with the Company and its parent and subsidiaries for any reason other than death; (iii) twelve (12) months after the Participant's death; or (iv) any other date specified by the Committee when the NSO is granted. (b) Option Price. At the time granted, the Board of Directors will fix the Option Price, which will be no less than eighty-five percent (85%) of the Fair Market Value of the shares subject to the NSO on the Award Date. (c) Other Option Provisions. The form of NSO authorized by the Plan may contain such other provisions as the Committee may from time to time determine. 8. Terms and Conditions of Stock Appreciation Rights The Committee may, in its discretion, grant an SAR to any Participant under the Plan. Each SAR shall be evidenced by an agreement between the Company and the Participant, and may relate to and be associated with all or any part of a specific ISO or NSO. An SAR shall entitle the Participant to whom it is granted the right, so long as such SAR is exercisable and subject to such limitations as the Committee shall have imposed, to surrender any then exercisable portion of his SAR and, if applicable, the related ISO or NSO, in whole or in part, and receive from the Company in exchange, without any payment of cash (except for applicable employee withholding taxes), that number of shares of Common Stock having an aggregate Fair Market Value on the date of surrender equal to the product of (i) the excess of the Fair Market Value of a share of Common Stock on the date of surrender over the Fair Market Value of the Common Stock on the date the SARs were issued, or, if the SARs are related to an ISO or an NSO, the per share Option Price under such ISO or NSO on the Award Date, and (ii) the number of shares of Common Stock subject to such SAR, and, if applicable, the related ISO or NSO or portion thereof which is surrendered. An SAR granted in conjunction with an ISO or NSO shall terminate on the same date as the related ISO or NSO and shall be exercisable only if the Fair Market Value of a share of Common Stock exceeds the Option Price for the related ISO or NSO, and then shall be exercisable to the extent, and only to the extent, that the related ISO or NSO is exercisable. The Committee may at the time of granting any SAR add such additional conditions and limitations to the SAR as it shall deem advisable, including, but not limited to, limitations on the period or periods within which the SAR shall be exercisable and the maximum amount of appreciation to be recognized with regard to such SAR. If a Participant is subject to Section 16(a) and Section 16(b) of the Exchange Act, the Committee may at any time add such additional conditions and limitations to such SAR which, in its discretion, the Committee deems necessary or desirable to comply with such Section 16(a) or Section 16(b) and the rules and regulations issued thereunder, or to obtain any exemption therefrom. Any ISO or NSO or portion thereof which is surrendered with an SAR shall no longer be exercisable. The Committee, in its sole discretion, may allow the Company to settle all or part of the Company's obligation arising out of the exercise of an SAR by the payment of cash equal to the aggregate Fair Market Value of the shares of Common Stock which the Company would otherwise be obligated to deliver. 9. Terms and Conditions of Restricted Stock Awards All shares of Common Stock awarded to Participants under the Plan as Restricted Stock shall be subject to the following express terms and conditions and to such other terms and conditions, not inconsistent with the Plan, as the Committee shall deem appropriate: (a) Restricted Period. Shares of Restricted Stock awarded to Participants may not be sold, assigned, transferred, pledged or otherwise encumbered before they vest. Subject to the provisions of paragraphs (b) and (d) below and any other restrictions imposed by law, any shares of Restricted Stock that vest will be transferred, subject only to the restrictions set forth in Section 20, to the Participant or, in the event of his death, to the beneficiary or beneficiaries designated by writing filed by the Participant with the Committee for such purpose or, if none, to his estate. Delivery of shares in accordance with the preceding sentence shall be made within the thirty-day period after they vest. (b) Forfeitures. A Participant shall forfeit all unpaid accumulated dividends and all shares of Restricted Stock which have not vested prior to the date that his employment with the Company is terminated for any reason. (c) Certificates Deposited With Company. Each certificate issued in respect of shares of Restricted Stock awarded under the Plan shall be registered in the name of the Participant and deposited with the Company. Each such certificate shall bear the following (or a similar) legend: "The transferability of this certificate and the shares of stock represented hereby are subject to the terms and conditions (including forfeiture) relating to Restricted Stock contained in the AMCOL International Corporation 1993 Stock Plan and an Agreement entered into between the registered owner and AMCOL International Corporation. Copies of such Plan and Agreement are on file at the principal office of AMCOL International Corporation." (d) Stockholder Rights. Subject to the foregoing restrictions, each Participant shall have all the rights of a stockholder with respect to his shares of Restricted Stock including, but not limited to, the right to vote and to receive dividends on such shares. 10. Terms and Conditions of Phantom Stock The Committee may, in its discretion, award Phantom Stock to any Participant under the Plan. Each Award of Phantom Stock shall be evidenced by an agreement between the Company and the Participant. An Award of Phantom Stock shall entitle the Participant to whom it is awarded the right to elect, so long as such Phantom Stock is vested and subject to such limitations as the Committee shall have imposed, to surrender any then vested portion of the Phantom Stock, in whole or in part, and receive from the Company in exchange for the Fair Market Value of the Common Stock to which the surrendered Phantom Stock relates, payable either in cash or in shares of Common Stock as the Committee may determine. The Committee may at the time of awarding any Phantom Stock add such additional conditions and limitations to the Phantom Stock as it shall deem advisable, including, but not limited to, limitations on the period or periods within which the Phantom Stock may be surrendered, and the maximum amount of appreciation to be recognized with regard to such Phantom Stock. 11. Manner of Exercise of Options To exercise an Option in whole or in part, a Participant (or, after his death, his executor or administrator) must give written notice to the Committee, stating the number of shares with respect to which he intends to exercise the Option. The Company will issue the shares with respect to which the Option is exercised upon payment in full of the Option Price. The Committee may permit the Option Price to be paid in cash or shares of Common Stock held by the Participant having an aggregate Fair Market Value, as determined on the date of delivery, equal to the Option Price. The Committee may also permit the Option Price to be paid by any other method permitted by law, including by delivery to the Committee from the Participant of an election directing the Company to withhold the number of shares of Common Stock from the Common Stock otherwise due upon exercise of the Option having an aggregate Fair Market Value on that date equal to the Option Price. If a Participant pays the Option Price with shares of Common Stock which were received by the Participant upon exercise of one or more ISOs, and such Common Stock has not been held by the Participant for at least the greater of: (a) two years from the date the ISOs were granted or (b) one year after the transfer of the shares of Common Stock to the Participant, the use of the shares shall constitute a disqualifying disposition and the ISO underlying the shares used to pay the Option Price shall no longer satisfy all of the requirements of Code Section 422. 12. Vesting A Participant may not exercise an Option or surrender Phantom Stock or an SAR until it has become vested. Similarly, no share of Restricted Stock may be sold, transferred, reassigned, pledged or otherwise encumbered or disposed of until it is vested. The portion of an Award of Options, SARs, Restricted Stock and/or Phantom Stock that is vested depends upon the period that has elapsed since the Award Date. The following schedule applies to any Award of Options, SARs, Restricted Stock and Phantom Stock under this Plan unless the Committee establishes a different vesting schedule on the Award Date: Number of Years Since Award Date Vested Percentage Fewer than two........................................ None Two but fewer than three ............................. 40% Three but fewer than four............................. 60% Four but fewer than five.............................. 80% Five or more.......................................... 100% Notwithstanding anything herein to the contrary, however, all Awards will become vested and exercisable upon the effective date of a "change in control" and will remain exercisable during the thirty (30) days following the effective date of the change in control. As used in this paragraph, the term "change in control" means the change in the legal or beneficial ownership of fifty-one percent (51%) of the outstanding shares of Common Stock of the Company within a six-month period, other than by death or operation of law, or the sale of ninety percent (90%) or more of the assets of the Company. Regardless of the period elapsed since the Award Date, a Participant's Awards become fully vested if his employment with the Company and its parent and subsidiaries terminates for any of the following reasons: (a) retirement on or after his sixty-fifth (65th) birthday; (b) retirement on or after his fifty-fifth (55th) birthday with consent of the Company; (c) retirement at any age on account of total and permanent disability as determined by the Company; or (d) death. If a Participant terminates employment with the Company for any reason, he forfeits any Awards that are not yet vested. A transfer from the Company to a subsidiary or affiliate, or vice versa, is not a termination of employment for purposes of this Plan. 13. Adjustments to Reflect Changes in Capital Structure If there is any change in the corporate structure or shares of the Company, the Committee may make any adjustments necessary to prevent accretion, or to protect against dilution, in the number and kind of shares authorized by the Plan and, with respect to outstanding Awards, in the number and kind of shares covered thereby and in the applicable Option Price. For the purpose of this Section 13, a change in the corporate structure or shares of the Company includes, without limitation, any change resulting from a recapitalization, stock split, stock dividend, consolidation, rights offering, separation, reorganization, or liquidation and any transaction in which shares of Common Stock are changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or another corporation. 14. Nontransferability of Awards Awards under the Plan are not transferable, voluntarily or involuntarily, other than by will or by the laws of descent and distribution. During a Participant's lifetime, his Options may be exercised only by him. 15. Rights as Stockholder No Common Stock may be delivered upon the exercise of any Option until full payment has been made. A Participant has no rights whatsoever as a stockholder with respect to any shares covered by an Option until the date of the issuance of a stock certificate for the shares. 16. Withholding Tax The Company shall have the right to withhold in cash or shares of Common Stock with respect to any payments made to Participants under the Plan any taxes required by law to be withheld because of such payments. 17. No Right to Employment Participation in the Plan will not give any Participant a right to be retained as an employee of the Company or its parent or subsidiaries, or any right or claim to any benefit under the Plan, unless the right or claim has specifically accrued under the Plan. 18. Amendment of the Plan The Board of Directors may from time to time amend or revise the terms of this Plan in whole or in part and may, without limitation, adopt any amendment deemed necessary; provided, however, that (a) no change in any Award previously granted to a Participant may be made that would impair the rights of the Participant without the Participant's consent, (b) no amendment may extend the period in which a Participant may exercise an ISO beyond the period set forth in Section 6(a)(ii), and (c) the Board of Directors may not, without approval by the holders of a majority of the shares of the Company present at a stockholders meeting, (i) change the aggregate number of shares that may be granted pursuant to Options and Restricted Stock granted under the Plan (except in accordance with the provisions of Section 13), (ii) change the class of eligible employees who may receive Awards under the Plan, (iii) adopt any amendment affecting the Option Price at which Options may be granted, or (iv) materially increase benefits accruing to Participants under the Plan. 19. Stockholder Approval Operation of the Plan shall be subject to approval by the stockholders of the Company within twelve months before or after the date the Plan is adopted by the Board of Directors in accordance with Rule 16b-3(b) of the Exchange Act. If such stockholder approval is obtained at a duly held stockholders' meeting, it may be obtained by the affirmative vote of the holders of a majority of the shares of the Company present at the meeting or represented and entitled to vote thereon. If and in the event that the Company registers any class of any equity security pursuant to Section 12 of the Exchange Act, the approval of such stockholders of the Company shall be solicited substantially in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder, or (2) solicited after the Company has furnished in writing to the holders entitled to vote substantially the same information concerning the Plan as that which would be required by the rules and regulations in effect under Section 14(e) of the Exchange Act at the time such information is furnished. If such stockholder approval is obtained by written consent, it must be obtained by the unanimous written consent of all stockholders of the Company. 20. Conditions Upon Issuance of Shares An Option shall not be exercisable, a share of Common Stock shall not be issued pursuant to the exercise of an Option, and Restricted Stock shall not be awarded until such time as the Plan has been approved by the stockholders of the Company and unless the award of Restricted Stock, exercise of such Option and the issuance and delivery of such share pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the share of Common Stock may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the share of Common Stock is being purchased only for investment and without any present intention to sell or distribute such share if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law. 21. Effective Date and Termination of Plan 21.01 Effective Date. This Plan is effective as of the later of the date of its adoption by the Board of Directors, or the date it is approved by the stockholders of the Company, pursuant to Section 19. 21.02 Termination of the Plan. The Board of Directors may terminate the Plan at any time with respect to any shares that are not then subject to Options or Restricted Stock. Termination of the Plan will not affect the rights and obligations of any Participant with respect to Awards before termination.
