The Committee, in its sole discretion, shall prescribe the time or times at which, or the conditions upon which, an Option or portion thereof shall become vested and exercisable, and may accelerate the exercisability of any Option at any time. The period during which a vested Option may be exercised shall be ten years from the Date of Grant, unless a shorter exercise period is specified by the Committee in an Award, subject to such limitations as may apply under an Award relating to the termination of a Participant's employment or other service with the Company or any Subsidiary or any other cancellation of an Option in accordance with this Plan or an Award Agreement. 6.4 Option Exercise; Withholding. Subject to such terms and conditions as shall be specified in an Award, an Option may be exercised in whole or in part at any time during the term thereof by written notice to the Company, together with payment of the aggregate exercise price therefor. Payment of the exercise price shall be made, at the discretion of the Committee as specified in the Award Agreement, by (i) payment in cash or cash equivalent acceptable to the Committee, (ii) payment in Common Shares that have been held by the Participant for at least six months (or such other period as the Committee may deem appropriate for purposes of applicable accounting rules), valued at the Fair Market 4 Value of such shares on the date of exercise, (iii) a broker-assisted "cashless exercise," (iv) a combination of the methods described above, or (v) such other method as may be approved by the Committee and set forth in the Award Agreement. In addition to and at the time of payment of the exercise price, the Participant shall pay to the Company the full amount of any and all applicable income tax and employment tax amounts required to be withheld in connection with such exercise, payable under such of the methods described above for the payment of the exercise price of the Options as may be approved by the Committee. 6.5 Limited Transferability of Nonqualified Options. All Options shall be nontransferable except (i) upon the Participant's death, by the Participant's will or the laws of descent and distribution or (ii) in the case Nonqualified Options only, on a case-by-case basis as may be approved by the Committee in its discretion, in accordance with the terms provided below. An award for a Nonqualified Option may provide that the Participant shall be permitted to, during his or her lifetime and subject to the prior approval of the Committee at the time of proposed transfer, transfer all or part of the Option to the Participant's family member (as defined in the Award Agreement in a manner consistent with the requirements for the Form S-8 registration statement, if applicable). The transfer of a Nonqualified Option may be subject to such other terms and conditions as the Committee may in its discretion impose from time to time. Subsequent transfers of an Option shall be prohibited other than by will or the laws of descent and distribution upon the death of the transferee. 6.6 Additional Rules for Incentive Options. (a) Eligibility. An Incentive Option may only be granted to an Eligible Person who is considered an employee of the Company or any Subsidiary for purposes of Treasury Regulations Section 1.421-7(h). (b) Annual Limits. No Incentive Option shall be granted to a Participant as a result of which the aggregate Fair Market Value (determined as of the Date of Grant) of the share with respect to which Incentive Options are exercisable for the first time in any calendar year under the Plan and any other share option plans of the Company, any Subsidiary, or any parent Company, would exceed $100,000, determined in accordance with Section 422(d) of the Code. This limitation shall be applied by taking Options into account in the order in which granted. (c) Termination of Employment. An Award of an Incentive Option may provide that such Option may be exercised not later than 3 months following termination of employment of the Participant with the Company and all Subsidiaries, or not later than one year following death and disability, as and to the extent determined by the Committee to be consistent with the requirements of Section 422 of the Code and Treasury Regulations thereunder. (d) Other Terms and Conditions; Nontransferability. Any Incentive Option granted hereunder shall contain such additional terms and conditions, not inconsistent with the terms of this Plan, as are deemed necessary or desirable by the Committee, which terms, together with the terms of this Plan, shall be intended and interpreted to cause such Incentive Option to qualify as an incentive stock option under Section 422 of the Code. Such terms shall include, if applicable, limitations on Incentive Options granted to ten-percent owners of the Company. An Award Agreement for an Incentive Option may provide that such Option shall be treated as a Nonqualified Option to the extent that certain requirements applicable to incentive options under the Code shall not be satisfied. An Incentive Option shall by its terms be nontransferable otherwise than by will or by the laws of descent and distribution, and shall be exercisable during the lifetime of a Participant only by such Participant. (e) Disqualifying Dispositions. If Common Shares acquired by exercise of an Incentive Option are disposed of within two years following the Date of Grant or one year following the issuance of such 5 shares to the Participant upon exercise, the Participant shall, promptly following such disposition, notify the Company in writing of the date and terms of such disposition and provide such other information regarding the disposition as the Committee may reasonably require. 7. SHARE APPRECIATION RIGHTS 7.1 Grant of SARs. A Share Appreciation Right granted to a Participant is an Award in the form of a right to receive, upon surrender of the right but without other payment, an amount based on appreciation in the Fair Market Value of Common Shares over a base price established for the Award, exercisable at such time or times and upon conditions as may be approved by the Committee. The maximum number of shares of Common Shares that may be subject to SARs granted to any Participant during any calendar year shall be limited to 1,000,000 shares (subject to adjustment as provided in Section 0 hereof). An SAR may be granted, at the discretion of the Committee, together with a Dividend Equivalent Right with respect to the same number of Common Shares. 7.2 Freestanding SARs. A Share Appreciation Right may be granted without any related Option, and in such case, will be exercisable as determined by the Committee, but in no event after 10 years from the Date of Grant. The base price of an SAR granted without any related Option shall be determined by the Committee in its sole discretion; provided, however, that the base price per share of any such freestanding SAR shall not be less than 100 percent of the Fair Market Value of the Common Shares on the Date of Grant. 7.3 Tandem SARs. A Share Appreciation Right may be granted in connection with an Option, either at the time of grant or at any time thereafter during the term of the Option. An SAR granted in connection with an Option will entitle the holder, upon exercise, to surrender such Option or any portion thereof to the extent unexercised, with respect to the number of shares as to which such SAR is exercised, and to receive payment of an amount computed as described in Section 0 hereof. Such Option will, to the extent and when surrendered, cease to be exercisable. An SAR granted in connection with an Option hereunder will have a base price per share equal to the per share exercise price of the Option, will be exercisable at such time or times, and only to the extent, that a related Option is exercisable, and will expire no later than the related Option expires. 7.4 Payment of SARs. An SAR will entitle the holder, upon exercise of the SAR, to receive payment of an amount determined by multiplying: (i) the excess of the Fair Market Value of a the Common Shares on the date of exercise of the SAR over the base price of such SAR, by (ii) the number of shares as to which such SAR is exercised. Payment of the amount determined under the foregoing may be made, in the discretion of the Committee, in cash, in Common Shares valued at their Fair Market Value on the date of exercise, or in a combination of cash and Common Shares. 8. RESTRICTED SHARE AWARDS 8.1 Grant of Restricted Share Awards. A Restricted Share Award to a Participant represents Common Shares that are issued subject to such restrictions on transfer and other incidents of ownership and such forfeiture conditions as the Committee may determine. The Committee may, in connection with any Restricted Share Award, require the payment of a specified purchase price. The maximum number of Common Shares that may be subject to Restricted Share Awards granted to all Participants during the term of the Plan shall be limited to 1,000,000 shares (subject to adjustment as provided in Section 0 hereof). 8.2 Vesting Requirements. The restrictions imposed on shares granted under a Restricted Share Award shall lapse in accordance with the vesting requirements specified by the Committee in the 6 Award Agreement. Such vesting requirements may be based on the continued employment of the Participant with the Company or its Subsidiaries for a specified time period or periods, and may also be based on the attainment of specified business goals or measures established by the Committee in its sole discretion. 8.3 Restrictions. Shares granted under any Restricted Share Award may not be transferred, assigned or subject to any encumbrance, pledge, or charge until all applicable restrictions are removed or have expired, unless otherwise allowed by the Committee. The Committee may require the Participant to enter into an escrow agreement providing that the certificates representing the shares granted or sold under a Restricted Share Award will remain in the physical custody of an escrow holder until all restrictions are removed or have expired. Failure to satisfy any applicable restrictions shall result in the subject shares of the Restricted Share Award being forfeited and returned to the Company, with any purchase price paid by the Participant to be refunded, unless otherwise provided by the Committee. The Committee may require that certificates representing the shares granted under a Restricted Share Award bear a legend making appropriate reference to the restrictions imposed. 8.4 Rights as Shareholder. Subject to the foregoing provisions of this Section 0 and the applicable Award Agreement, the Participant will have all rights of a shareholder with respect to the shares granted to him under a Restricted Share Award, including the right to vote the shares and receive all dividends and other distributions paid or made with respect thereto, unless the Committee determines otherwise at the time the Restricted Share Award is granted. 8.5 Section 83(b) Election. The Committee may provide in an Award Agreement that the Restricted Share Award is conditioned upon the Participant's refraining from making an election with respect to the Award under Section 83(b) of the Code. Irrespective of whether an Award is so conditioned, if a Participant makes an election pursuant to Section 83(b) of the Code with respect to a Restricted Share Award, the Participant shall be required to promptly file a copy of such election with the Company. 9. SHARE UNIT AWARDS 9.1 Grant of Share Unit Awards. A Share Unit Award is an Award to a Participant of a number of hypothetical share units with respect to Common Shares, with an initial value based on the Fair Market Value of the Common Shares on the Date of Grant. A Share Unit Award shall be subject to such restrictions and conditions as the Committee shall determine. A Share Unit Award may be granted, at the discretion of the Committee, together with a Dividend Equivalent Right with respect to the same number of Common Shares. 9.2 Vesting of Share Unit Awards. The Committee may determine and provide in the Award Agreement any installment or other vesting period of a Share Unit Award. Vesting requirements may be based on the continued employment of the Participant with the Company or its Subsidiaries for a specified time period or periods. Vesting requirements may also be based on the attainment of specified business goals or measures established by the Committee in its sole discretion. Share Units may also be granted on a fully vested basis, with a deferred payment date. 9.3 Payment of Share Unit Awards. A Share Unit Award shall become payable to a Participant at the time or times determined by the Committee and set forth in the Award Agreement, which may be upon or following the vesting of an Award. The payment with respect to each share unit under a Share Unit Award shall be determined by reference to the Fair Market Value of one Common Share on each applicable payment date. Payment may be made, at the discretion of the Committee, in cash or in Common Shares, or in a combination thereof, subject to applicable tax withholding. 7 9.4 No Rights as Stockholder. The Participant shall not have any rights as a shareholder with respect to the Common Shares subject to a Share Unit Award until such time as any Common Shares are delivered to the Participant pursuant to the terms of the Award. 10.

Such events shall include, but shall not be limited to, termination of employment for cause, violation of material Company policies, breach of noncompetition, confidentiality or other restrictive covenants that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company. 12. GENERAL PROVISIONS 12.1 No Assignment or Transfer; Beneficiaries. Except as provided in Section 0 hereof, Awards under the Plan shall not be assignable or transferable, except by will or by the laws of descent and distribution, and during the lifetime of a Participant, the Award shall be exercised only by such Participant or by his guardian or legal representative. Notwithstanding the foregoing, the Committee may provide in the terms of an Award Agreement that the Participant shall have the right to designate a beneficiary or beneficiaries who shall be entitled to any rights, payments or other specified benefits under an Award following the Participant's death. 12.2 Deferrals of Payment. Notwithstanding any other provisions of the Plan, the Committee may permit a Participant to defer the receipt of payment of cash or delivery of Common Shares that would otherwise be due to the Participant by virtue of the exercise of a right or the satisfaction of vesting or other conditions with respect to an Award. If any such deferral is to be permitted by the Committee, the Committee shall establish the rules and procedures relating to such deferral, including, without limitation, the period of time in advance of payment when an election to defer may be made, the time period of the deferral and the events that would result in payment of the deferred amount, the interest or other earnings attributable to the deferral and the method of funding, if any, attributable to the deferred amount. 12.3 Rights as Shareholder. A Participant shall have no rights as a holder of Common Shares with respect to any unissued securities covered by an Award until the date the Participant becomes the 9 holder of record of such securities. Except as provided in Section 0 hereof, no adjustment or other provision shall be made for dividends or other shareholder rights, except to the extent that the Award Agreement provides for a Dividend Equivalent Right, or otherwise provides for dividend payments or similar economic benefits. 12.4 Employment or Service. Nothing in the Plan, in the grant of any Award or in any Award Agreement shall confer upon any Eligible Person the right to continue in the capacity in which he is employed by, or otherwise serves, the Company or any Subsidiary. 12.5 Securities Laws. No Common Shares will be issued or transferred pursuant to an Award unless and until all then applicable requirements imposed by federal and state securities and other laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any exchanges upon which the Common Shares may be listed, have been fully met. As a condition precedent to the issuance of shares pursuant to the grant or exercise of an Award, the Company may require the Participant to take any reasonable action to meet such requirements. The Committee may impose such conditions on any Common Shares issuable under the Plan as it may deem advisable, including, without limitation, restrictions under the Securities Act of 1933, as amended, under the requirements of any exchange upon which such shares of the same class are then listed, and under any blue sky or other securities laws applicable to such shares. 12.6 Tax Withholding. The Participant shall be responsible for payment of any taxes or similar charges required by law to be withheld from an Award or an amount paid in satisfaction of an Award, which shall be paid by the Participant on or prior to the payment or other event that results in taxable income in respect of an Award. The Award Agreement shall specify the manner in which the withholding obligation shall be satisfied with respect to the particular type of Award. 12.7 Unfunded Plan. The adoption of this Plan and any setting aside of cash amounts or Common Shares by the Company with which to discharge its obligations hereunder shall not be deemed to create a trust or other funded arrangement. The benefits provided under this Plan shall be a general, unsecured obligation of the Company payable solely from the general assets of the Company, and neither a Participant nor the Participant's permitted transferees or estate shall have any interest in any assets of the Company by virtue of this Plan, except as a general unsecured creditor of the Company. Notwithstanding the foregoing, the Company shall have the right to implement or set aside funds in a grantor trust, subject to the claims of the Company's creditors, to discharge its obligations under the Plan. 12.8 Section 162(m) Compliance.

The adoption of the Plan shall not affect any other share incentive or other compensation plans in effect for the Company or any Subsidiary, nor shall the Plan preclude the Company from establishing any other forms of share incentive or other compensation for employees of the Company or any Subsidiary. The amount of any compensation deemed to be received by a Participant pursuant to an Award shall not constitute compensation with respect to which any other employee benefits of such Participant are determined, including, without limitation, benefits under any bonus, pension, profit sharing, life insurance or salary continuation plan, except as otherwise specifically provided by the terms of such plan. 10 12.10 Plan Binding on Transferees. The Plan shall be binding upon the Company, its transferees and assigns, and the Participant, his executor, administrator and permitted transferees and beneficiaries. 12.11 Construction and Interpretation.

Headings of Sections hereof are inserted for convenience and reference and constitute no part of the Plan. 12.12 Severability. If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any other jurisdiction. 12.13 Fractional Shares. No fractional shares shall be issued or delivered pursuant to this Pan or any Award. The Committee shall determine whether cash, Common Shares, Share Options or other property shall be issued or paid in lieu of fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated. 12.14 Other Jurisdictions. The Committee may adopt, amend and terminate such arrangements and grant such Awards, not inconsistent with the intent of the Plan, as it may deem necessary or desirable to comply with or take advantage of tax, securities, regulatory or other laws of other jurisdictions with respect to Participants who are subject to such laws. The terms and conditions of such Awards may vary from the terms and conditions that would otherwise be required by the Plan solely to the extent the Committee deems necessary for such purpose. 12.15 Governing Law.
