SECTION 2

ADMINISTRATION

2.1. The Committee. This Plan will be administered by the Committee. The decision or action of a majority of the actual number of members of the Committee will constitute the decision or action of the Committee. The Committee will consist of not less than three Directors. The members of the Committee will be appointed from time to time by, and will serve at the pleasure of, the Board. The Committee will be comprised solely of Directors who are (a) “nonemployee directors” under Rule 16b-3, and (b) “outside directors” as described in Treasury Regulation Section 1.162-27(e)(3), and (c) “independent” under the director independence requirements of the NASDAQ Stock Market or, if it changes, the principal securities exchange or market on which the Shares are then traded or listed. Failure of the Committee to be so comprised will not result in the cancellation, termination, expiration or lapse of any Award.

2.2. Authority of the Committee. Except as limited by law or by the Articles of Incorporation or By-Laws of the Company, and subject to the provisions of this Plan, the Committee will have full power and discretion to: (a) select Employees and Non-employee Directors who will participate in the Plan; (b) determine the sizes and types of Awards; (c) determine the terms and conditions of Awards in a manner consistent with this Plan; (d) construe and interpret this Plan, all Award Agreements and any other agreements or instruments entered into under this Plan; (e) establish, amend or waive rules and regulations for the Plan’s administration; and (f) amend the terms and conditions of any outstanding Award and applicable Award Agreement to the extent such terms and conditions are within the discretion of

the Committee as provided in this Plan; provided however, the Committee may only accelerate the exercisability or vesting of an Award in connection with a Participant’s death, Disability, Retirement, or in connection with a Change in Control. The Committee may also accelerate the exercisability or vesting of an Award to the extent such actions involve an aggregate number of Shares not in excess of five percent of the number of Shares initially available for Awards.

2.3. Delegation by the Committee. The Committee, in its sole discretion and on such terms and conditions as it may provide, may delegate all or any part of its authority and powers under this Plan to one or more Directors or officers of the Company; provided, however, that the Committee may not delegate its authority and powers (a) with respect to grants to Section 16 Persons, (b) in any way which would jeopardize this Plan’s qualification under Code Section 162(m) or Rule 16b-3 or (c) adversely impact Awards under Rule 16b-3.

2.4. Decisions Binding. All determinations and decisions made by the Committee, the Board and any delegate of the Committee pursuant to Section 2.3 will be final, conclusive and binding on all persons, including the Company and Participants. No such determinations will be subject to de novo review if challenged in court.

2.5. Considerations in Establishing Performance Goals. In determining appropriate Performance Goals and the relative weight accorded each Performance Goal, the Committee must:

2.5.1. Balance risk and financial results in a manner that does not encourage Participants to expose the Company and its Subsidiaries to unnecessary or excess risks; and

2.5.2. Monitor the success of the Performance Goals and weighting established in prior years, alone and in combination with other incentive compensation awarded to the same Participants, and make appropriate adjustments in future calendar years as needed so that payments appropriately incentivize Participants and appropriately reflect risk.

SECTION 3

SHARES SUBJECT TO THIS PLAN

3.1. Number of Shares.

3.1.1. Maximum Number. Subject to adjustment as provided in Section 3.6, the maximum number of Shares cumulatively available for issuance under this Plan pursuant to the: (a) exercise of Options; (b) grant of SARs; (c) grant of Shares of Restricted Stock; (d) payment of Performance Share Units or (e) issuance of Bonus Stock, will not exceed One Million (1,000,000) Shares plus; (i) Shares tendered (actually or by attestation) to the Company in connection with the exercise of Options; (ii) Shares purchased by the Company in the open market or otherwise using the cash proceeds upon the exercise of Options; (iii) Shares settled hereunder in cash; (iv) Shares withheld pursuant to Section 11; and (v) the number of Shares equal to the value, as determined by the Committee in its sole discretion, of the income tax deductions recognized by the

Company in connection with the exercise of Non-Qualified Stock Options and disqualifying dispositions of Shares acquired on the exercise of Incentive Stock Options, determined as of the date on which the Company’s federal income tax return is filed less the total number of Shares previously issued under this Plan, and less the total number of Shares then subject to outstanding Options or other Awards. The foregoing share reserve will be supplemented by an additional number of Shares that remain in acquired company plans that are assumed by the Company.

3.1.2. Limits Based on Award Type. In calculating the number of Shares available for issuance under this Plan, (a) no more than Five Hundred Thousand (500,000) Shares will be cumulatively available for the grant of Options or SARs under this Plan, and (b) during any Fiscal Year, no Participant will be granted an Option or SAR for more than Fifty Thousand (50,000) Shares. Shares issued under this Plan may be either authorized but unissued Shares, treasury Shares or reacquired Shares (including Shares purchased in the open market), or any combination thereof, as the Committee may from time to time determine in its sole discretion.

3.1.3. Forfeited and Unpurchased Shares. Shares covered by an Award that are forfeited or that remain unpurchased or undistributed upon termination or expiration of the Award may be made the subject of further Awards to the same or other Participants. If the exercise price of any Option is satisfied by tendering Shares (by either actual delivery or attestation), only the number of Shares actually issued, net of the Shares tendered, will be deemed issued for purposes of determining the number of Shares available for Awards under this Plan. Additionally, if Shares are withheld pursuant to Section 11.2, only the number of Shares actually issued, net of the Shares withheld, will be deemed issued for purposes of determining the number of Shares available for Awards under this Plan.

3.2. Release of Shares. Subject to the limitations set forth in this Plan, the Committee will have full authority to determine the number of Shares available for Awards and, in its sole discretion, may include (without limitation) as available for distribution (a) any Shares that have ceased to be subject to an Award; (b) any Shares subject to an Award that have been previously forfeited; (c) any Shares under an Award that otherwise terminates without the issuance of Shares being made to a Participant; (d) any Shares that are received by the Company in connection with the exercise of an Award, including the satisfaction of any tax liability or tax withholding obligation; or (e) any Shares repurchased by the Company in the open market or otherwise, having an aggregate repurchase price no greater than the amount of cash proceeds received by the Company from the exercise of Options granted under this Plan. Any Shares that are available immediately prior to the termination of the Plan, or any Shares returned to the Company for any reason subsequent to the termination of the Plan, may be transferred to a successor plan.

3.3. Restrictions on Shares. Shares issued upon exercise of an Award will be subject to the terms and conditions specified herein and to such other terms, conditions and restrictions as the Committee in its sole discretion may determine and provide in the Award Agreement. The Company will not be required to issue or deliver any certificates for Shares, cash or other property prior to the (a) listing of such Shares on any stock exchange (or other public market) on which the Shares may then be listed (or regularly traded), and (b) completion of any registration

or qualification of such shares under federal, state, local or other law, or any ruling or regulation of any government body which the Committee determines to be necessary or advisable. The Company may cause any certificate for any Shares to be delivered hereunder to be properly marked with a legend or other notation reflecting the limitations on transfer of such Shares as provided in this Plan or as the Committee may otherwise require. Participants, or any other persons entitled to benefits under this Plan, must furnish to the Committee such documents, evidence, data or other information as the Committee considers necessary or desirable for the purpose of administering this Plan. The benefits under this Plan for each Participant, and each other person who is entitled to benefits hereunder, are to be provided on the condition that he furnish full, true and complete data, evidence or other information, and that he promptly signs any document reasonably related to the administration of this Plan requested by the Committee. No fractional Shares will be issued under this Plan; rather, fractional shares will be aggregated and then rounded to the next lower whole Share.

3.4. Shareholder Rights. Except with respect to Restricted Stock as provided in Section 7 and dividend rights as provided in Section 3.5, no person will have any rights of a shareholder (including, but not limited to, voting rights) as to Shares subject to an Award until, after proper exercise or vesting of the Award or other action as may be required by the Committee in its sole discretion, such Shares have been recorded on the Company’s official shareholder records (or the records of its transfer agents or registrars) as having been issued and transferred to the Participant. Upon exercise of the Award or any portion thereof, the Company will have a reasonable period in which to issue and transfer the Shares to the Participant, and the Participant will not be treated as a shareholder for any purpose whatsoever prior to such issuance and transfer. No payment or adjustment will be made for rights for which the record date is prior to the date such Shares are recorded as issued and transferred in the Company’s official shareholder records (or the records of its transfer agents or registrars), except as otherwise provided herein or in an Award Agreement.

3.5. Dividends and Dividend Equivalents. The Committee may provide that Awards denominated in Shares earn dividends or dividend equivalents. Such dividends and dividend equivalents may be paid currently in cash or Shares or may be credited to an account established by the Committee in the Participant’s name. In addition, dividends or dividend equivalents paid on outstanding Awards or issued Shares may be credited to such account rather than paid currently. Any crediting of dividends or dividend equivalents may be subject to such restrictions and conditions as the Committee may establish, including reinvestment in additional Shares or Share equivalents. Notwithstanding the foregoing, dividends or dividend equivalents on unvested portions of Awards whose vesting is subject to the achievement of specified Performance Goals may, as set forth in an Award Agreement, be subject to the same restrictions as the underlying Shares or units to which such dividends or dividend equivalents relate.

3.6. Changes in Stock.

3.6.1. Substitution of Stock and Assumption of Plan. In the event of any change in the Shares by virtue of any stock dividends, stock splits, recapitalizations or reclassifications or any acquisition, merger, consolidation, share exchange, tender offer or other combination involving the Company that does not constitute a Change in Control but that results in the acquisition of a Subsidiary by the Company, or in the event that

other stock is substituted for the Shares as the result of any merger, consolidation, share exchange or reorganization or any similar transaction which constitutes a Change in Control of the Company, the Committee will correspondingly adjust the (a) number, kind and class of Shares which may be delivered under this Plan, (b) number, kind, class and price of Shares subject to outstanding Awards (except for mergers or other combinations in which the Company is the surviving entity), and (c) numerical limits of Sections 3.1, 6.1, 7.1, 8.1 and 9.1, all in such manner as the Committee in its sole discretion determines to be advisable or appropriate to prevent the dilution or diminution of such Awards; provided, however, in no event will the One Hundred Thousand and 00/100 Dollar ($100,000) limit on Incentive Stock Options contained in Section 5.1 be affected by an adjustment under this Section 3.6.1. The Committee’s determinations under this Section 3.6.1 will be final and conclusive.

3.6.2. Conversion of Shares. In the event of a Change in Control of the Company pursuant to which another person or entity acquires control of the Company (such other person or entity being the “Successor”), the kind of shares of stock which are subject to this Plan and to each outstanding Award will, automatically by virtue of such Change in Control, be converted into and replaced by securities of the Successor, having full voting, dividend, distribution, preference and liquidation rights, and the number of shares subject to an Award, the calculation of an Award’s value and the purchase price per share upon exercise of the Award will be correspondingly adjusted so that, by virtue of such Change in Control of the Company, each Participant will (a) in the case of Options, have the right to purchase (i) that number of shares of stock of the Successor which have a Fair Market Value, as of the date of such Change in Control of the Company, equal to the Fair Market Value, as of the date of such Change in Control of the Company, of the Shares of the Company theretofore subject to each Option, and (ii) for a purchase price per share which, when multiplied by the number of shares of stock of the Successor subject to each Option, will equal the aggregate exercise price at which the Participant could have acquired all of the Shares previously optioned to the Participant; and (b) in the case of Awards other than Options, have the right to receive that number of shares of stock of the Successor which have a Fair Market Value, as of the date of such Change in Control of the Company, equal to the Fair Market Value, as of the date of the Change in Control of the Company, of the Shares of the Company to which each Award relates. The Committee, in its sole discretion, will determine the method by which Awards of Performance Share Units will be adjusted due to a Change in Control of the Company. Shares issued in connection with the Awards that are assumed, converted or substituted under this Section 3.6.2 will not reduce the number of Shares reserved for issuance under Section 3.1.

3.7. Book-Entry Securities. The Company shall have the right to maintain all Awards in book-entry form in the name of the Participant until such time as such Awards shall have been vested and the requirements of Section 3.3 have been met.

SECTION 4

Except as herein provided, the individuals who are eligible to participate in this Plan and be granted Awards are those individuals who are Employees of the Company or any Affiliate and Non-employee Directors of the Company. The Committee may, from time to time and in its sole discretion, select Employees and Non-employee Directors of the Company to be granted Awards and will determine the terms and conditions with respect thereto. In making any such selection and in determining the form of the Award, the Committee may give consideration to the functions and responsibilities of the Employees or Non-employee Director to the Company or its Affiliates, the value of the Employee or Non-employee Director’s services (past, present and future) to the Company or its Affiliates and such other factors deemed relevant by the Committee in its sole discretion. An Employee or Non-employee Director will become a Participant in this Plan as of the date specified by the Committee. A Participant can be removed as an active Participant by the Committee effective as of any date; provided, however, that no such removal will adversely affect any Award previously granted to the Participant.

4.2. No Contract of Employment. Neither this Plan nor any Award Agreement executed hereunder will constitute a contract of employment between an Employee and the Company or an Affiliate, and participation in this Plan will not give an Employee the right to be rehired by or retained in the employment of the Company or an Affiliate.

4.3. No Right to Be Retained on Board. Neither this Plan nor any Award Agreement executed hereunder will give any Director the right to be retained, nominated or re-elected as a Director.

SECTION 5

STOCK OPTIONS

5.1. Grant of Options. Subject to the terms and provisions of this Plan, the Committee, at any time and from time to time, may grant Options to any Employee or Non-employee Director in such amounts as the Committee, in its sole discretion, may determine. The Committee may grant Incentive Stock Options, Nonqualified Stock Options or any combination thereof; provided, however, Non-employee Directors may not be granted Incentive Stock Options. Subject to the terms and provisions of this Plan, the Committee, in its sole discretion, will determine the number of Shares subject to each Option; provided, however, no Participant may be granted Incentive Stock Options under this Plan which would result in Shares with an aggregate Fair Market Value (measured on the Grant Date(s)) of more than One Hundred Thousand Dollars ($100,000) first becoming exercisable in any one calendar year.

5.2. Option Award Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the Exercise Price, the number of Shares to which the Option pertains, the Exercise Period, any conditions to exercise of the Option and such other terms and conditions as the Committee, in its sole discretion, determines. The Award Agreement will also specify whether the Option is intended to be an Incentive Stock Option or a Nonqualified Stock

Option. All grants of Options intended to constitute Incentive Stock Options will be made in accordance, and all Award Agreements pursuant to which Incentive Stock Options are granted will comply, with the requirements of Code Section 422.

5.3. Exercise Price. The Exercise Price for each Option will be determined by the Committee under this Section 5.3; provided, however, except in connection with a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding Awards may not be amended to reduce the exercise price of outstanding Options or cancel outstanding Options in exchange for cash, other Awards or Options with an exercise price that is less than the exercise price of the original Options without shareholder approval.

5.3.1. Nonqualified Stock Options. In the case of a Nonqualified Stock Option, the Exercise Price per Share will be determined by the Committee; provided, however, in no event will the Exercise Price be less than 100 percent of the Fair Market Value of the Shares to which the Nonqualified Stock Option relates, determined as of the Grant Date.

5.3.2. Incentive Stock Options. In the case of an Incentive Stock Option, the Exercise Price will be not less than 100 percent of the Fair Market Value of the Shares to which the Incentive Stock Option relates determined as of the Grant Date; provided, however, that if, on the Grant Date, the Participant (together with persons whose stock ownership is attributed to the Participant pursuant to Code Section 424(d)) owns securities possessing more than 10 percent of the total combined voting power of all classes of stock of the Company or any of its Subsidiaries, the Exercise Price will be not less than 110 percent of the Fair Market Value of the Shares to which the Incentive Stock Option relates, determined as of the Grant Date.

5.3.3. Substitute Options. Notwithstanding the provisions of Sections 5.3.1 and 5.3.2, in the event that the Company or an Affiliate consummates a transaction described in Code Section 424(a) (e.g., the acquisition of property or stock from an unrelated corporation), individuals who become Employees on account of such transaction may be granted Options in substitution for options granted by such former employer. If such substitute Options are granted, the Committee, in its sole discretion and consistent with Code Section 424(a), shall determine the Exercise Price of such substitute Options. In carrying out the provisions of this Section 5.3.3, the Committee will apply the principles contained in Section 3.6.

5.4. Duration of Options. Subject to the terms and provisions of Sections 10 and 12, the Exercise Period with respect to each Option will commence and expire at such times as the Committee provides in the Award Agreement, provided that:

(a) Incentive and Nonqualified Stock Options will not be exercisable later than the tenth anniversary of their respective Grant Dates;

(b) Incentive Stock Options granted to an Employee who possesses more than ten percent of the total combined voting power of all classes of Shares of the Company, taking into

account the attribution rules of Code Section 422(d), will not be exercisable later than the fifth anniversary of their Grant Date(s); and

(c) Subject to the limits of this Section 5, the Committee may, in its sole discretion, after an Option is granted, extend the maximum term of the Option to a date not later than the earlier of (i) the end of the Exercise Period of the Options or (ii) the tenth anniversary of the Grant Date. Any such extension of an Option pursuant to this subsection will comply with the requirements of Code Section 409A, if applicable.

5.5. Exercisability of Options. Subject to the provisions of Section 12 and this Section 5, all Options granted under this Plan will be exercisable at such times, under such terms and subject to such restrictions and conditions as the Committee determines in its sole discretion and as specified in the Award Agreements to which the Options relate. After an Option is granted, the Committee, in its sole discretion, may accelerate the exercisability of the Option.

5.6. Method of Exercise. Subject to the provisions of this Section 5 and the applicable Award Agreement, a Participant may exercise an Option, in whole or in part, at any time during the Exercise Period to which the Option relates by giving written notice to the Company of exercise on a form provided by the Committee (if available). Such notice will specify the number of Shares subject to the Option to be purchased and will be accompanied by payment in full of the total Exercise Price by cash or check or such other form of payment as the Company may accept. If permitted by the applicable Award Agreement, payment in full or in part may also be made by:

(a) Delivering Shares already owned by the Participant that have a total Fair Market Value on the date of such delivery equal to the total Exercise Price;

(b) The delivery of cash by a broker-dealer as a Cashless Exercise, if permitted by the Committee and the applicable Award Agreement;

(c) Reducing the number of Shares issued upon the exercise by the largest number of whole Shares that has a Fair Market Value that does not exceed the aggregate exercise price for the Shares exercised under this method. Shares will no longer be outstanding under an Option (and will therefore not thereafter be exercisable) following the exercise of such Option to the extent of (i) Shares used to pay the exercise price of an Option under the “net exercise” method discussed in this Section 5.6(c), (ii) Shares actually delivered to the Participant as a result of such exercise and (iii) any Shares withheld for purposes of tax withholding; or

(d) Any combination of the foregoing.

If payment of the Exercise Price of an Option is made in whole or in part in the form of Restricted Stock, a number of the Shares to be received upon such exercise equal to the number of shares of Restricted Stock used for payment of the Exercise Price will be subject to the same forfeiture restrictions or deferral limitations to which the Restricted Stock was subject, unless otherwise determined by the Committee in its sole discretion.

No Shares will be issued until full payment therefor has been made. Subject to any forfeiture restrictions or deferral limitations that may apply if an Option is exercised using

Restricted Stock, a Participant will have all of the rights of a shareholder of the Company holding the class of Shares subject to the Option (including, if applicable, the right to vote the Shares) when the Participant has given written notice of exercise, has paid the total Exercise Price, and such Shares have been recorded on the Company’s official shareholder records (or the records of its transfer agents or registrars) as having been issued and transferred to the Participant.

5.7. Restrictions on Share Transferability. In addition to the restrictions imposed by Section 14.7, the Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option as it may deem advisable or appropriate in its sole discretion, including, but not limited to, restrictions related to applicable Federal and state securities laws and the requirements of the NASDAQ Stock Market or any other national securities exchange or market on which Shares are then listed or traded.

5.8. Termination by Reason of Death, Disability or Retirement. Unless otherwise provided in the Award Agreement or determined by the Committee in its sole discretion, if a Participant incurs a Termination of Service due to death or Disability, all unexpired and unexercised Options held by such Participant, regardless of their vested status, will thereafter be fully exercisable until the expiration of the Exercise Period. If a Participant incurs a Termination of Service due to Retirement, any vested, unexpired and unexercised Options held by such Participant will thereafter be fully exercisable until the expiration of the Exercise Period.

5.9. Other Termination. Unless otherwise provided in the Award Agreement or determined by the Committee in its sole discretion, if a Participant incurs a Termination of Service that is involuntary on the part of the Participant (but is not due to death or Disability and is not with Cause) or is voluntary on the part of the Participant (but is not due to Retirement), any Options held by such Participant will terminate on the Termination of Service, except that such Options, to the extent exercisable at the time of Termination of Service, may be exercised until the expiration of the shorter of the following two periods: (a) the 30 consecutive-day period commencing on the date of Termination of Service, or (b) the date on which the Exercise Period expires. If a Participant incurs a Termination of Service which is with Cause, all of his Options, whether or not exercisable, will terminate immediately as of the date of such Termination of Service.

5.10. Special Provision for Incentive Stock Options. Notwithstanding any other provision of this Plan to the contrary, an Incentive Stock Option will not be exercisable more than (a) three months after the Participant’s Termination of Service for any reason other than Disability, or (b) one year after the Participant’s Termination of Service by reason of Disability.

SECTION 6

STOCK APPRECIATION RIGHTS

6.1. Grant of SARs. Subject to the terms and conditions of this Plan, the Committee, at any time and from time to time, may grant SARs to any Employee or Non-employee Director in such amounts as the Committee, in its sole discretion, determines. The Committee, in its sole discretion, may grant SARs in any combination thereof.

6.1.1. Number of Shares. Subject to the limitations of Section 3, the Committee will have complete discretion to determine the number of SARs granted to any Participant.

6.1.2. Exercise Price and Other Terms. The Committee, subject to the provisions of this Plan, will have complete discretion to determine the terms and conditions of SARs granted under this Plan.

6.2. SAR Award Agreement. Each SAR will be evidenced by an Award Agreement that specifies the exercise price, the expiration date of the SAR, the number of SARs, any conditions on the exercise of the SAR and such other terms and conditions as the Committee, in its sole discretion, determines.

6.3. Expiration of SARs. Each SAR granted under this Plan will expire upon the date determined by the Committee, in its sole discretion, as set forth in the applicable Award Agreement; provided, however, that no SAR will be exercisable later than the tenth anniversary of its Grant Date.

6.4. Payment of SAR Amount. Upon exercise of a SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

(a) The positive difference between the Fair Market Value of a Share on the date of exercise and the exercise price; by

(b) The number of Shares with respect to which the SAR is exercised.

At the sole discretion of the Committee, the payment may be in cash, in Shares which have a Fair Market Value equal to the cash payment calculated under this Section 6.4, or in a combination of cash and Shares.

6.5. Termination by Reason of Death, Disability or Retirement. Unless otherwise provided in the Award Agreement or determined by the Committee in its sole discretion, if a Participant incurs a Termination of Service due to death or Disability, any unexpired and unexercised SARs held by such Participant, regardless of their vested status, will thereafter be fully exercisable until the expiration of the Exercise Period. If a Participant incurs a Termination of Service due to Retirement, any vested, unexpired and unexercised SARs held by such Participant will thereafter be fully exercisable until the expiration of the Exercise Period.

6.6. Other Termination. Unless otherwise provided in the Award Agreement or determined by the Committee in its sole discretion, if a Participant incurs a Termination of Service that is involuntary on the part of the Participant (but is not due to death or Disability and is not with Cause) or is voluntary on the part of the Participant (but is not due to Retirement), any SARs held by such Participant will terminate on the Termination of Service, except that such SARs, to the extent exercisable at the time of Termination of Service, may be exercised until the expiration of the shorter of the following two periods: (a) the 30 consecutive-day period commencing on the date of Termination of Service, or (b) the date on which the Exercise Period expires. If a Participant incurs a Termination of Service which is with Cause, all of his SARs,

whether or not exercisable, will terminate immediately as of the date of such Termination of Service.

SECTION 7

RESTRICTED STOCK

7.1. Grant of Restricted Stock. Subject to the terms and provisions of this Plan, the Committee, at any time and from time to time, may grant Shares of Restricted Stock to any Employee or Non-employee Director in such amounts as the Committee, in its sole discretion, determines. Subject to the limitations of Section 3, the Committee, in its sole discretion, will determine the number of Shares of Restricted Stock to be granted to each Participant.

7.2. Restricted Stock Award Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that specifies the Period of Restriction, the number of Shares granted and such other terms and conditions as the Committee, in its sole discretion, determines. Unless the Committee in its sole discretion determines otherwise, Shares of Restricted Stock will be held by the Company, and will not be delivered to any Participant until the end of the applicable Period of Restriction.

7.3. Transferability. Except as provided in Section 3.3, Section 14.7, and this Section 7, Shares of Restricted Stock may not be sold, transferred, assigned, margined, encumbered, gifted, bequeathed, alienated, hypothecated, pledged or otherwise disposed of, whether by operation of law, whether voluntarily or involuntarily or otherwise, until the end of the applicable Period of Restriction.

7.4. Other Restrictions. The Committee, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate in accordance with this Section 7.

7.4.1. General Restrictions. The Committee may impose restrictions on Restricted Stock based upon any of the following criteria: (a) the achievement of specific Company-wide, Affiliate-based, Subsidiary-based, divisional, individual Participant or other Performance Goals, (b) applicable Federal or state securities laws, or (c) any other basis determined by the Committee in its sole discretion; provided, however, except for (i) Awards of deferred Shares received in lieu of other Awards, (ii) Awards made to Employees to replace their awards from a prior employer that were forfeited upon the acquisition of the prior employer by the Company, and (iii) the Participant’s death, Retirement or Disability, the required period of service for full vesting will be set forth in an Award Agreement. Notwithstanding the foregoing, any performance-based Awards of Restricted Stock must be held for at least one-year before they can be earned.

7.4.2. Section 162(m) Performance Restrictions. Notwithstanding any other provision of this Section 7.4.2 to the contrary, for purposes of qualifying grants of Restricted Stock as “performance-based compensation” to Covered Employees under Code Section 162(m), the Committee will establish restrictions based upon the achievement of Performance Goals. The specific targets under the Performance Goals

that must be satisfied for the Period of Restriction to lapse or terminate will be set by the Committee on or before the latest date permissible to enable the Restricted Stock to qualify as “performance-based compensation” under Code Section 162(m). The Performance Goals for a Covered Employee under this Section 7.4.2 will be one or more of the business criteria listed under Section 1.3.32. In granting Restricted Stock that is intended to qualify as “performance-based compensation” under Code Section 162(m), the Committee will follow any procedures determined by it in its sole discretion from time to time to be necessary, advisable or appropriate to ensure qualification of the Restricted Stock as “performance-based compensation” under Code Section 162(m).

7.4.3. Legend on Certificates. The Committee, in its sole discretion, may require the placement of a legend on certificates representing Shares of Restricted Stock to give appropriate notice of such restrictions. For example, the Committee may determine that some or all certificates representing Shares of Restricted Stock will bear the following legend:

“THE SALE, PLEDGE OR OTHER TRANSFER OF THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE, WHETHER VOLUNTARY, INVOLUNTARY OR BY OPERATION OF LAW, IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER UNDER FEDERAL AND STATE SECURITIES LAWS AND UNDER THE MAINSOURCE FINANCIAL GROUP, INC. 2015 STOCK INCENTIVE PLAN, AS SET FORTH IN AN AWARD AGREEMENT EXECUTED THEREUNDER. A COPY OF SUCH PLAN AND SUCH AWARD AGREEMENT MAY BE OBTAINED FROM THE CORPORATE SECRETARY OF MAINSOURCE FINANCIAL GROUP, INC.”

7.5. Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under this Plan will be released to a Participant as soon as practicable after the end of the applicable Period of Restriction. Except in the case of grants of Restricted Stock to Covered Employees which are intended to qualify as “performance-based compensation” under Code Section 162(m) (the vesting of which cannot be accelerated except as provided in Section 12.1), the Committee, in its sole discretion, may accelerate the time at which any restrictions will lapse or remove any restrictions. After the end of the applicable Period of Restriction, the Participant will be entitled to have any restrictive legend or legends placed on the Shares under Section 7.4.3 removed from his or her Share certificate.

7.6. Voting Rights. During the Period of Restriction, Participants holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the applicable Award Agreement provides otherwise.

7.7. Return of Restricted Stock to Company. On the date set forth in the applicable Award Agreement, the Restricted Stock for which restrictions have not lapsed by the last day of the Period of Restriction will revert to the Company and thereafter will be available for the grant of new Awards under this Plan.

7.8. Termination of Service. Unless otherwise provided in an Award Agreement or determined by the Committee in its sole discretion, in the event of a Participant’s Termination of Service due to death or Disability during the Period of Restriction, the restrictions on his Shares of Restricted Stock will lapse and the Participant (or his or her Beneficiary) will, on the date of such Termination of Service, be fully vested in the Restricted Stock. Unless otherwise provided in an Award Agreement or this Plan, in the event of a Participant’s Termination of Service for any reason during the Period of Restriction other than a Termination of Service due to death or Disability, all Shares of Restricted Stock still subject to restriction will be forfeited by the Participant and thereafter be available for the grant of new Awards under this Plan; provided, however, that the Committee will have the sole discretion to waive, in whole or in part, subject to the restrictions of Section 7.4.1, any or all remaining restrictions with respect to any or all of such Participant’s Shares of Restricted Stock. Notwithstanding any other provision of this Section 7 to the contrary, in the case of grants of Restricted Stock to Covered Employees that the Committee intends to qualify as “performance-based compensation” under Code Section 162(m) (the vesting of which cannot be accelerated, except as provided in Section 12.1), no shares of Restricted Stock will become vested unless the applicable Performance Goals have first been met; provided, further, that the Committee will not waive any restrictions with respect to such Restricted Stock. If the vesting of shares of Restricted Stock is accelerated after the applicable Performance Goals have been met, the amount of Restricted Stock distributed will be discounted by the Committee to reasonably reflect the time value of money in connection with such early vesting.

SECTION 8

PERFORMANCE SHARE UNITS

8.1. Grant of Performance Share Units. Subject to the terms and provisions of this Plan, the Committee, at any time and from time to time, may grant Performance Share Units to any Employee or Non-employee Director in such amounts as the Committee, in its sole discretion, determines. Subject to the limitations of Section 3, the Committee will have complete discretion in determining the number of Performance Share Units granted to each Participant.

8.2. Value of Performance Share Units. Each Performance Share Unit will have an initial value that is established by the Committee on or before the Grant Date. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the Grant Date.

8.3. Performance Goals and Other Terms. The Committee will set Performance Goals in its sole discretion which, depending on the extent to which they are met, will determine the number or value of Performance Share Units, or both, that will be paid to the Participant. Each Award of Performance Share Units will be evidenced by an Award Agreement that specifies the number of Performance Share Units, the Performance Period, the Performance Goals and such other terms and conditions as the Committee, in its sole discretion, determines.

8.3.1. General Performance Goals. The Committee may set Performance Goals based upon (a) the achievement of Company-wide, Affiliate-based, Subsidiary-based, divisional, individual Participant or other Performance Goals; (b) in either absolute terms or relative to the performance of one or more comparable companies or an

index which includes several companies; (c) applicable Federal or state securities laws; or (d) any other basis determined by the Committee in its sole discretion. Measurement of Performance Goals may exclude impact of charges for restructuring, discontinued operations, extraordinary items, other unusual or non-recurring items and the cumulative effects of accounting changes, each as defined by generally accepted accounting principles.

8.3.2. Code Section 162(m) Performance Objectives. Notwithstanding any other provision of this Section 8.3.2 to the contrary, for purposes of qualifying grants of Performance Share Units to Covered Employees as “performance-based compensation” under Code Section 162(m), the Committee will establish the specific targets under the Performance Goals applicable to Performance Share Units. Such targets under the Performance Goals will be set by the Committee on or before the latest date permissible to enable the Performance Share Units, as the case may be, to qualify as “performance-based compensation” under Code Section 162(m). The Performance Goals for a Covered Employee under this Section 8.3.2 will be one or more of the business criteria listed under Section 1.3.32. In granting Performance Share Units to Covered Employees which are intended to qualify as “performance-based compensation” under Code Section 162(m), the Committee will follow any procedures determined by it from time to time to be necessary or appropriate in its sole discretion to ensure qualification of the Performance Share Units, as the case may be, as “performance-based compensation” under Code Section 162(m).

8.4. Earning of Performance Share Units. After the applicable Performance Period has ended, the holder of Performance Share Units will be entitled to receive those Performance Share Units, as the case may be, earned by the Participant over the Performance Period, to be determined as a function of the extent to which the applicable Performance Goals have been achieved. Except in the case of Performance Goals applicable to Performance Share Units granted to Covered Employees which are intended to qualify as “performance-based compensation” under Code Section 162(m) (which cannot be reduced or waived except as provided in Section 12.1), after the grant of a Performance Share Unit, the Committee, in its sole discretion, may reduce or waive any Performance Goals or related business criteria applicable to such Performance Share Unit.

8.5. Form and Timing of Payment of Performance Share Units. Payment of earned Performance Share Units will be made as soon as practicable in the calendar year after the end of the applicable Performance Period. The Committee, in its sole discretion, may pay earned Performance Share Units in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Share Units, as the case may be, determined as of the last day of the applicable Performance Period) or a combination thereof.

8.6. Termination of Service. Unless otherwise provided in an Award Agreement or determined by the Committee in its sole discretion, in the event of a Participant’s Termination of Service for any reason prior to the last day of the Performance Period, Performance Share Units applicable to the Performance Period will be forfeited and thereafter be available for the grant of new Awards under this Plan. Notwithstanding any other provision of this Section 8 to the contrary, in the case of Awards of Performance Share Units to Covered Employees that the

Committee intends to qualify as performance-based compensation” under Code Section 162(m) (the vesting of which cannot be accelerated except as provided in Section 12.1), no Performance Share Units will become vested until the applicable Performance Goals have been met.

SECTION 9
BONUS STOCK AWARDS

9.1. Bonus Stock Awards. An Award of Bonus Stock may be made in consideration for past services actually rendered to the Company or any Affiliate for its benefit. Each Award Agreement relating to an Award of Bonus Stock will be in such form and will contain such terms and conditions as the Committee will deem appropriate. Each Bonus Stock Award Agreement will include (through the incorporation of these provisions by reference or otherwise) the substance of each of the following provisions:

9.2. Vesting. Shares awarded under a Bonus Stock Award Agreement may, but need not, be subject to vesting, as determined by the Committee and specified in the applicable Award Agreement. Upon a Change in Control, any Bonus Stock, to the extent subject to vesting, will be immediately vested.

9.3. Form and Timing of Payment of Bonus Stock. Payment of earned Bonus Stock will be made at the time set forth in an Award Agreement.

9.4. Termination of Service. Upon a Grantee’s Termination of Service, the Company may reacquire any or all of the Bonus Stock held by the Grantee which has not yet vested as the date of the Termination of Service under the terms of the Bonus Stock Award Agreement. If as of the Termination of Service the restrictions applicable to a Bonus Stock Award, if any, have not been satisfied, the Bonus Stock Award will be forfeited and the underlying shares of Company Stock returned to the Company.

SECTION 10

AMENDMENT, TERMINATION, AND DURATION

10.1. Amendment, Suspension, or Termination. The Board may supplement, amend, alter or discontinue this Plan in its sole discretion at any time and from time to time, but no supplement, amendment, alteration or discontinuation will be made which would impair the rights of a Participant under an Award without the Participant’s consent, except that any supplement, amendment, alteration or discontinuation may be made to (a) avoid a material charge or expense to the Company or an Affiliate, (b) cause this Plan to comply with applicable law, or (c) permit the Company or an Affiliate to claim a tax deduction under applicable law. In addition, subject to the provisions of this Section 10.1, the Board, in its sole discretion at any time and from time to time, may supplement, amend, alter or discontinue this Plan without the approval of the Company’s shareholders (a) to the extent such approval is not required by applicable law or the terms of a written agreement, and (b) so long as any such amendment or alteration does not increase the number of Shares subject to this Plan (other than pursuant to Section 3.6) or increase the maximum number of Options, SARs, Shares of Restricted Stock, Performance Share Units or Bonus Stock that the Committee may award to an individual

Participant under this Plan. The Committee may supplement, amend, alter or discontinue the terms of any Award theretofore granted, prospectively or retroactively, on the same conditions and limitations (and exceptions to limitations) as apply to the Board under the foregoing provisions of this Section 10.1, and further subject to any approval or limitations the Board may impose. Notwithstanding the foregoing, in no event may the Board or the Committee amend the repricing provisions of the Plan or any Award without approval of the Company’s shareholders.

10.2. Duration of this Plan and Shareholder Approval. This Plan will be effective on the Effective Date and, subject to Section 10.1 (regarding the Board’s right to supplement, amend, alter or discontinue this Plan), will remain in effect until the tenth anniversary thereof. No Option will be exercised and no other Award will be exercised or otherwise paid hereunder until this Plan has been approved by the holders of at least a majority of the outstanding Shares represented in person or by proxy at a meeting at which approval of this Plan is considered; and provided further, no Incentive Stock Option may be granted under this Plan after the tenth anniversary of the Effective Date.

SECTION 11

TAX WITHHOLDING

11.1. Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to the payment or exercise of an Award, the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy all Federal, state and local income and employment taxes required by applicable law to be withheld with respect to the payment or exercise of such Award. In no event will any amount withheld be in an amount that would require the Company to incur accounting charges.

11.2. Withholding Arrangements. The Committee, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy a tax withholding obligation, in whole or in part, by (a) electing to have the Company withhold otherwise deliverable Shares (except in the case of exercises of Incentive Stock Options), or (b) delivering to the Company Shares then owned by the Participant having a Fair Market Value equal to the amount required to be withheld. The amount of the withholding requirement will be deemed to include any amount that the Committee agrees may be withheld at the time any such election is made, not to exceed, in the case of income tax withholding, the amount determined, based upon minimum statutory requirements, by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date the amount of income tax to be withheld is determined. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

SECTION 12

CHANGE IN CONTROL

12.1. Change in Control.

12.1.1. Continuation, Assumption or Replacement of Awards. In the event of a Change in Control, the surviving or successor entity (or its parent corporation) may continue, assume or replace Awards outstanding as of the date of the Change in Control (with such adjustments as may be required or permitted by Section 3.6), and such Awards or replacements therefore shall remain outstanding and be governed by their respective terms, subject to Section 12.1.4. A surviving or successor entity may elect to continue, assume or replace only some Awards or portions of Awards. For purposes of this Section 12.1.1, an Award shall be considered assumed or replaced if, in connection with the Change in Control and in a manner consistent with Code Sections 409A and 424, either (a) the contractual obligations represented by the Award are expressly assumed by the surviving or successor entity (or its parent corporation) with appropriate adjustments to the number and type of securities subject to the Award and the exercise price thereof that preserves the intrinsic value of the Award existing at the time of the Change in Control, or (b) the Participant has received a comparable equity-based award that preserves the intrinsic value of the Award existing at the time of the Change in Control and provides for a vesting or exercisability schedule that is the same as or more favorable to the Participant.

12.1.2. Acceleration of Awards. If and to the extent that outstanding Awards under the Plan are not continued, assumed or replaced in connection with a Change in Control, then (a) outstanding Options and Stock Appreciation Rights issued to the Participant that are not yet fully exercisable shall immediately become exercisable in full and shall remain exercisable in accordance with their terms, (b) all unvested Restricted Stock Awards, Stock Unit Awards and Performance Awards will become immediately fully vested and non-forfeitable; and (c) any Performance Criteria applicable to Restricted Stock Awards, Stock Unit Awards and Performance Awards will be deemed to have been satisfied at the target level of performance specified in connection with the applicable Award.

12.1.3. Payment for Awards. If and to the extent that outstanding Awards under the Plan are not continued, assumed or replaced in connection with a Change in Control, then the Committee may terminate some or all of such outstanding Awards, in whole or in part, as of the effective time of the Change in Control in exchange for payments to the holders as provided in this Section 12.1.3. The Committee will not be required to treat all Awards similarly for purposes of this Section 12.1.3. The payment for any Award or portion thereof terminated shall be in an amount equal to the excess, if any, of (a) the fair market value (as determined in good faith by the Committee) of the consideration that would otherwise be received in the Change in Control for the number of Shares subject to the Award or portion thereof being terminated, or, if no consideration is to be received by the Company’s stockholders in the Change in Control, the Fair Market Value of such number of shares immediately prior to the effective date of the Change in Control, over (b) the aggregate exercise price (if any) for the Shares subject to the Award or portion thereof being terminated. If there is no excess, the Award may be terminated without payment. Any payment shall be made in such form, on such terms and subject to such conditions as the Committee determines in its discretion, which may or may not be the same as the form, terms and conditions applicable to payments to the Company’s

stockholders in connection with the Change in Control, and may include subjecting such payments to vesting conditions comparable to those of the Award surrendered.

12.1.4. Termination after a Change in Control. If and to the extent that Awards are continued, assumed or replaced under the circumstances described in Section 12.1.1, and if within two years after the Change in Control a Participant experiences an involuntary Termination of Service or other service for reasons other than Cause, then (a) outstanding Options and Stock Appreciation Rights issued to the Participant that are not yet fully exercisable shall immediately become exercisable in full and shall remain exercisable in accordance with their terms, (b) all unvested Restricted Stock Awards, Performance Share Units and Bonus Stock will become immediately fully vested and non-forfeitable; and (c) any Performance Criteria applicable to Restricted Stock, Performance Share Units and Bonus Stock will be deemed to have been satisfied at the target level of performance specified in connection with the applicable Award.

12.2. Definition. For purposes of Section 12.1, a “Change in Control” of the Company will be deemed to have occurred if the conditions or events set forth in any one or more of the following subsections occur:

(a) The consummation of any merger, consolidation or similar transaction which involves the Company and in which persons who are the shareholders of the Company immediately prior to the transaction own, immediately after the transaction, shares of the surviving or combined entity which possess voting rights equal to or less than 50 percent of the voting rights of all shareholders of such entity, determined on a fully diluted basis;

(b) Any sale, lease, exchange, transfer or other disposition of all or any substantially all of the consolidated assets of the Company;

(c) Any tender, exchange, sale or other disposition (other than disposition of the stock of the Company in connection with bankruptcy, insolvency, foreclosure, receivership or other similar transactions) or purchase (other than purchases by the Company or any Company sponsored employee benefit plan, or purchases by members of the Board of Directors of the Company or any subsidiary) of shares of stock which represent more than 25 percent of the voting power of the Company;

(d) During any period of two consecutive years, individuals who at the date of the adoption of the Plan constitute the Board cease for any reason to constitute at least a majority thereof, unless the nomination of each director at the beginning of the period has been approved by directors representing at least a majority of the directors then in office;

Notwithstanding the foregoing, a Change in Control of the Company (i) will not occur as a result of the issuance of stock by the Company in connection with any public offering of its stock; (ii) will not be deemed to have occurred with respect to any transaction unless such transaction has been approved or shares have been tendered by a majority of the shareholders who are not Section 16 Persons; or (iii) will not occur due to stock ownership by the MainSource Financial Group, Inc. Employee Stock Ownership Plan Trust Agreement, which forms a part of

the MainSource Financial Group, Inc. 401(k) and Employee Stock Ownership Plan or any other employee benefit plan.

SECTION 13

LEGAL CONSTRUCTION

13.1. Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also includes the feminine, the plural includes the singular, and the singular includes the plural.

13.2. Severability. In the event any provision of this Plan is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of this Plan, and this Plan will be construed and enforced as if the illegal or invalid provision had never been included herein.

13.3. Requirements of Law. The grant of Awards and the issuance of Shares under this Plan will be subject to all applicable statutes, laws, rules and regulations and to such approvals and requirements as may be required from time to time by any governmental authorities or any securities exchange or market on which the Shares are then listed or traded.

13.4. Governing Law. Except to the extent preempted by the Federal laws of the United States of America, this Plan and all Award Agreements will be construed in accordance with and governed by the laws of the State of Indiana without giving effect to any choice or conflict of law provisions, principles or rules (whether of the state of Indiana or any other jurisdiction) that would cause the application of any laws of any jurisdiction other than the state of Indiana.

13.5. Headings. The descriptive headings and sections of this Plan are provided herein for convenience of reference only and will not serve as a basis for interpretation or construction of this Plan.

13.6. Mistake of Fact. Any mistake of fact or misstatement of facts will be corrected when it becomes known by a proper adjustment to an Award or Award Agreement.

13.7. Evidence. Evidence required of anyone under the Plan may be by certificate, affidavit, document or other information which the person relying thereon considers pertinent and reliable, and signed, made or presented by the proper party or parties.

13.8. 409A Compliance. It is intended the Plan and all Awards hereunder be administered in a manner that will comply with, or comply with an exemption from, as applicable, the requirements of Code Section 409A, including any final regulations guidance issued by the Secretary of the Treasury and the Internal Revenue Service. The Committee is authorized to adopt rules or regulations deemed necessary or appropriate to qualify for an exemption from or to comply with the requirements of Code Section 409A. Notwithstanding anything in this Section to the contrary, with respect to any Award subject to Code Section 409A, no amendment to or payment under such Award will be made unless permitted under Code Section 409A and the regulations or rulings issued thereunder. Without limiting the generality of

the foregoing, if any amount shall be payable with respect to any Award hereunder as a result of a Participant’s Termination from Service at such time as the Participant is a “specified employee” (as defined for purposes of Code Section 409A) and such amount is subject to the provisions of Code Section 409A, then no payment shall be made, except as permitted under Code Section 409A prior to the first day of the seventh calendar month beginning after the participants’ separation from service (or the date of his or her earlier death).

Notwithstanding anything in the Plan to the contrary, none of the Company, the Committee nor any other person involved in the administration of this Plan shall in any way be responsible for ensuring the exemption of any Award from, or compliance by any Award with, the requirements of Code Section 409A. By accepting an Award under this Plan, each Participant acknowledges that neither the Company, the Committee nor any other person involved with the administration of this Plan has any duty or obligation to design or administer the Plan or Awards granted thereunder in an manner that minimizes a Participant’s tax liabilities, including the avoidance of additional tax liabilities under Code Section 409A.

SECTION 14

MISCELLANEOUS

14.1. No Effect on Employment or Service. Neither this Plan nor the grant of any Awards or the execution of any Award Agreement will confer upon any Participant any right to continued employment by the Company, retention on or nomination to the Board or will interfere with or limit in any way the right of the Company to terminate any Employee’s employment or service at any time, with or without Cause, or removal from the Board. Employment with the Company and its Affiliates is on an at-will basis only, unless otherwise provided by a written employment or severance agreement, if any, between the Employee and the Company or an Affiliate, as the case may be. If there is any conflict between the provisions of this Plan and an employment or severance agreement between a Participant and the Company, the provisions of such employment or severance agreement will control, including, but not limited to, the vesting and forfeiture of any Awards.

14.2. No Company Obligation. Unless required by applicable law, the Company, an Affiliate, the Board of Directors and the Committee will not have any duty or obligation to affirmatively disclose material information to a record or beneficial holder of Shares or an Award, and such holder will have no right to be advised of any material information regarding the Company or any Affiliate at any time prior to, upon or in connection with the receipt, exercise or distribution of an Award. In addition, the Company, an Affiliate, the Board, the Committee and any attorneys, accountants, advisors or agents for any of the foregoing will not provide any advice, counsel or recommendation to any Participant with respect to, without limitation, any Award, any exercise of an Option or any tax consequences relating to an Award.

14.3. Participation. No Employee or Non-employee Director will have the right to be selected to receive an Award under this Plan or, having been selected, to be selected to receive a future Award. Participation in the Plan will not give any Participant any right or claim to any benefit under this Plan, unless such right or claim has specifically accrued under the terms of this Plan.

14.4. Liability and Indemnification. No member of the Board, the Committee or any officer or employee of the Company or any Affiliate will be personally liable for any action, failure to act, decision or determination made in good faith in connection with this Plan. By participating in this Plan, each Participant agrees to release and hold harmless the Company and its Affiliates (and their respective directors, officers and employees) and the Committee from and against any tax liability, including, but not limited to, interest and penalties, incurred by the Participant in connection with his receipt of Awards under this Plan and the deferral, payment and exercise thereof. Each person who is or was a member of the Committee, or of the Board, will be indemnified and held harmless by the Company against and from (a) any loss, cost, liability or expense (including, but not limited to, attorneys’ fees) that may be imposed upon or reasonably incurred by him in connection with or resulting from any claim, action, suit or proceeding to which he may be a party or in which he may be involved by reason of any action taken or failure to act under this Plan or any Award Agreement; and (b) any and all amounts paid by him in settlement thereof, with the Company’s prior written approval, or paid by him in satisfaction of any judgment in any such claim, action, suit or proceeding against him; provided, however, that he will give the Company an opportunity, at the Company’s expense, to handle and defend such claim, action, suit or proceeding before he undertakes to handle and defend the same on his own behalf. The foregoing right of indemnification is exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation or By-Laws, by contract, as a matter of law or otherwise, or under any power that the Company may have to indemnify them or hold them harmless.

14.5. Successors. All obligations of the Company under this Plan, with respect to Awards granted hereunder, are binding on any successor to the Company, whether or not the existence of such successor is the result of a Change in Control of the Company.

The Company will not, and will not permit its Affiliates to, recommend, facilitate or agree or consent to a transaction or series of transactions which would result in a Change in Control of the Company unless and until the person or persons or entity or entities acquiring control of the Company as a result of such Change in Control agree(s) to be bound by the terms of this Plan insofar as it pertains to Awards theretofore granted and agrees to assume and perform the obligations of the Company and its Successor (as defined in Section 3.6.2) hereunder.

14.6. Beneficiary Designations. Any Participant may designate, on such forms as may be provided by the Committee for such purpose, a Beneficiary to whom any vested but unpaid Award will be paid in the event of the Participant’s death. Each such designation will revoke all prior designations by the Participant and will be effective only if given in a form and manner acceptable to the Committee. In the absence of any such designation, any vested benefits remaining unpaid at the Participant’s death will be paid to the Participant’s spouse, if any, and the to the Participant’s estate and, subject to the terms of this Plan and of the applicable Award Agreement, any unexercised vested Award may be exercised by the spouse, if any, and if not by the administrator or executor of the Participant’s estate.

14.7. Nontransferability of Awards. Except as provided in Sections 14.7.1 and 14.7.2, no Award under this Plan can be sold, transferred, assigned, margined, encumbered, bequeathed, gifted, alienated, hypothecated, pledged or otherwise disposed of, whether by operation of law, whether voluntarily or involuntarily or otherwise, other than by will or by the

laws of descent and distribution. In addition, no Award under this Plan will be subject to execution, attachment or similar process. Any attempted or purported transfer of an Award in contravention of this Plan or an Award Agreement will be null and void ab initio and of no force or effect whatsoever. All rights with respect to an Award granted to a Participant will be exercisable during his lifetime only by the Participant.

14.7.1. Limited Transfers of Nonqualified Stock Options. Notwithstanding the foregoing, the Committee may, in its sole discretion, permit the transfer of Nonqualified Stock Options by a Participant to (a) the Participant’s spouse, any children or lineal descendants of the Participant or the Participant’s spouse, or the spouse(s) of any such children or lineal descendants (“Immediate Family Members”), (b) a trust or trusts for the exclusive benefit of Immediate Family Members, or (c) a partnership or limited liability company in which the Participant and/or the Immediate Family Members are the only equity owners, (collectively, “Eligible Transferees”); provided, however, in the event the Committee permits the transferability of Nonqualified Stock Options granted to the Participant, the Committee may subsequently, in its sole discretion, amend, modify, revoke or restrict, without the prior consent, authorization or agreement of the Eligible Transferee, the ability of the Participant to transfer Nonqualified Stock Options that have not been already transferred to an Eligible Transferee. An Option that is transferred to an Immediate Family Member will not be transferable by such Immediate Family Member, except for any transfer by such Immediate Family Member’s will or by the laws of descent and distribution upon the death of such Immediate Family Member. Incentive Stock Options granted under this Plan are not transferable pursuant to this Section 14.7.

14.7.2. Exercise by Eligible Transferees. In the event that the Committee, in its sole discretion, permits the transfer of Nonqualified Stock Options by a Participant to an Eligible Transferee under Section 14.7.1, the Options transferred to the Eligible Transferee must be exercised by such Eligible Transferee and, in the event of the death of such Eligible Transferee, by such Eligible Transferee’s executor or administrator only in the same manner, to the same extent and under the same circumstances (including, but not limited to, the time period within which the Options must be exercised) as the Participant could have exercised such Options. The Participant, or in the event of his death, the Participant’s estate, will remain liable for all federal, state, local and other taxes applicable upon the exercise of a Nonqualified Stock Option by an Eligible Transferee.

14.8. No Rights as Shareholder. Except to the limited extent provided in Sections 3.4 and 7.6, no Participant (or any Beneficiary) will have any of the rights or privileges of a shareholder of the Company with respect to any Shares issuable pursuant to an Award (or the exercise thereof), unless and until certificates representing such Shares have been recorded on the Company’s official shareholder records (or the records of its transfer agents or registrars) as having been issued and transferred to the Participant (or his or her Beneficiary).

14.9. Mitigation of Excise Tax. Subject to any other agreement providing for the Company’s indemnification of the tax liability described herein, if any payment or right accruing to a Participant under this Plan (without the application of this Section 14.9), either alone or together with other payments or rights accruing to the Participant from the Company or an Affiliate would constitute a “parachute payment,” as defined in Code Section 280G and

regulations thereunder, such payment or right will be reduced to the largest amount or greatest right that will result in no portion of the amount payable or right accruing under this Plan being subject to an excise tax under Code Section 4999 or being disallowed as a deduction under Code Section 280G. The determination of whether any reduction in the rights or payments under this Plan is to apply will be made by the Committee in good faith after consultation with the Participant, and such determination will be conclusive and binding on the Participant. The Participant will cooperate in good faith with the Committee in making such determination and providing the necessary information for this purpose.

14.10. Funding. Benefits payable under this Plan to any person will be paid by the Company from its general assets. Shares to be issued hereunder will be issued directly by the Company from its authorized but unissued Shares or acquired by the Company on the open market, or a combination thereof. Neither the Company nor any of its Affiliates will be required to segregate on its books or otherwise establish any funding procedure for any amount to be used for the payment of benefits under this Plan. The Company or any of its Affiliates may, however, in its sole discretion, set funds aside in investments to meet any anticipated obligations under this Plan. Any such action or set-aside will not be deemed to create a trust of any kind between the Company and any of its Affiliates and any Participant or other person entitled to benefits under the Plan or to constitute the funding of any Plan benefits. Consequently, any person entitled to a payment under the Plan will have no rights greater than the rights of any other unsecured general creditor of the Company or its Affiliates.
