Such shares of Common Stock may be either authorized but unissued shares of Common Stock, shares of issued Common Stock held in the Company’s treasury, or a combination of both, at the discretion of the Company. Except as otherwise provided in this Section 5.1, any shares of Common Stock underlying an Award under the Plan or the Prior Plans that expires without being exercised, or is forfeited, cancelled or otherwise terminated without a distribution to a Participant of Common Stock, cash, or other benefit in lieu of Common Stock, shall again be available under the Plan; provided that any shares that again become available for Awards under this Section 5.1 shall be added back as 1.0 share if such shares were subject to Stock Options, SARs, or other appreciation-only Awards granted under the Plan or Prior Plans, and as 1.60 shares if such shares were subject to a Restricted Stock, Stock Unit, Performance Share, Performance Unit or other full-value stock-based Award granted under the Plan or Prior Plans. In applying the immediately preceding sentence, (i) shares of Common Stock tendered by Participants as full or partial payment of the Exercise Price to the Company upon exercise of Stock Options granted under the Plan or Prior Plans shall not again be available for issuance under the Plan, (ii) shares of Common Stock repurchased on the open market with the proceeds of the Exercise Price of a Stock Option shall not again be available for issuance under the Plan, (iii) if any share-settled SARs are exercised, the aggregate number of shares subject to such SARs shall be deemed issued under the Plan or Prior Plans and shall not again be available for issuance under the Plan, (iv) if any Stock Options are exercised through a reduction of shares subject to the Award (i.e., “net exercised”), the aggregate number of shares subject to such Stock Option shall be deemed issued under the Plan or Prior Plans and shall not again be available for issuance under the Plan, and (v) if any shares are withheld by, or otherwise remitted to, the Company to satisfy a Participant’s tax withholding obligations with respect to any Awards granted under the Plan or Prior Plans, such shares shall be deemed issued under the Plan and shall not again be available for issuance under the Plan. Awards that are payable only in cash are not subject to this Section 5.1.

In addition to the maximum shares of Common Stock available for Awards under the Plan described above, the remaining shares of Common Stock shall be reduced by 1.60 for each share of Common Stock awarded pursuant to Restricted Stock, Performance Shares, Performance Units, Stock Units, or other Awards with value denominated in full shares of Common Stock for purposes of determining any individual or aggregate award limitations under the Plan and for purposes of calculating the aggregate amount of Common Stock available for Awards under the Plan. Each share-settled SAR that is granted shall reduce the remaining shares of Common Stock available under this Section by one (1.0),

The maximum number of shares of Common Stock that may be issued to Participants in the aggregate under the Plan as ISOs is 833,333.

Notwithstanding the foregoing, Awards granted through the assumption of, or in substitution or exchange for, similar awards in connection with the acquisition of another corporation or business entity shall not be counted for purposes of applying the above limitations on numbers of shares available for Awards generally or any particular kind of Award under the Plan.

Adjustment to Shares.

Such adjustment shall be made successively each time any such change or distribution shall occur. In addition, in the event of any such change or distribution, in order to prevent dilution or enlargement of Participants’ rights under the Plan, the Committee shall have the authority to adjust, in an equitable manner, the number and kind of shares that may be issued under the Plan, the number and kind of shares subject to outstanding Awards, the Exercise Price applicable to outstanding Stock Options, and the Fair Market Value of the Common Stock and other value determinations applicable to outstanding Awards. Appropriate adjustments may also be made by the Committee in the terms of any Awards granted under the Plan to reflect such changes or distributions and to modify any other terms of outstanding Awards on an equitable basis, including modifications of performance goals and changes in the length of performance periods; provided, however, that any such modifications and/or changes to Performance-Based Awards do not disqualify compensation attributable to such Awards as “performance-based compensation” under Code Section 162(m). In addition, the Committee is authorized to make adjustments to the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events affecting the Company or the financial statements of the Company, or in response to changes in applicable laws, regulations, or accounting principles. Notwithstanding anything contained in the Plan to the contrary, any adjustment with respect to an ISO due to a change or distribution described in this Section 5.2 shall comply with the rules of Code Section 424(a), and in no event shall any adjustment be made which would render any ISO granted hereunder to be disqualified as an incentive stock option for purposes of Code Section 422.

The Committee may, in its sole discretion, grant Restricted Stock Awards to Employees, Group Employees, Nonemployee Directors, and/or Independent Contractors as additional compensation or in lieu of other compensation for Services to the Company, an Affiliate or a Group Company. A Restricted Stock Award shall consist of shares of Common Stock that are subject to such terms and conditions as the Committee in its sole discretion determines appropriate and sets forth in the Award Agreement including, without limitation, restrictions on the sale or other disposition of such shares, the Vesting Date with respect to such shares and the right of the Company to reacquire such shares for no consideration upon termination of the Participant’s Service within specified periods. With respect to shares of Common Stock subject to a Restricted Stock Award, the Participant shall have all of the rights of a holder of shares of Common Stock, including the right to receive dividends and to vote the shares, unless the Committee determines otherwise on the Award Date.

Stock Certificates. Except as otherwise provided in this Section 9.2, the Company will issue each Participant entitled to receive shares of Common Stock under the Plan a certificate for such shares. Such certificate will be registered in the name of the Participant and will bear an appropriate

Stock Units. The Committee may, in its sole discretion, grant Stock Units to Employees, Group Employees, Nonemployee Directors, and Independent Contractors as additional compensation or in lieu of other compensation for Services to the Company, an Affiliate or a Group Company. A Stock Unit is a hypothetical share of Common Stock represented by a notional account established and maintained (or caused to be established or maintained) by the Company for such Participant who receives a grant of Stock Units. Stock Units shall be subject to such terms and conditions as the Committee, in its sole discretion, determines appropriate and sets forth in the Award Agreement including, without limitation, determinations of the Vesting Date with respect to such Stock Units and the criteria for the Vesting of such Stock Units. Subject to Section 9.4, a Stock Unit granted by the Committee shall provide for payment in shares of Common Stock at such time or times as the Award Agreement shall specify. The Committee shall determine whether a Participant who has been granted a Stock Unit also shall be entitled to a Dividend Equivalent Right with respect to such Stock Unit.

Payout of Stock Units. Subject to a Participant’s election to defer in accordance with Section 18.4 below, upon the Vesting Date of a Stock Unit, the shares of Common Stock representing the Stock Unit shall be distributed to the Participant, unless the Committee, in its sole discretion, provides for the payment of the Stock Unit in cash (or partly in cash and partly in shares of Common Stock) equal to the value of the shares of Common Stock which would otherwise be distributed to the Participant.

Performance Shares. The Committee may, in its sole discretion, grant Performance Shares to Employees, Group Employees, Nonemployee Directors, and/or Independent Contractors as additional compensation or in lieu of other compensation for Services to the Company, an Affiliate or a Group Company. A Performance Share shall consist of a share or shares of Common Stock that are subject to such terms and conditions as the Committee, in its sole discretion, determines appropriate and sets forth in the Award Agreement including, without limitation, determining the performance goal or goals that, depending on the extent to which such goals are met, will determine the number and/or value of the Performance Shares that will be paid out or distributed to the Participant and any other Vesting criteria. Performance goals may be based on, without limitation, Company-wide, divisional and/or individual performance, as the Committee, in its sole discretion, may determine, and may be based on the performance measures listed in Section 12.3 below.

Performance Units. The Committee may, in its sole discretion, grant Performance Units to Employees, Group Employees, Nonemployee Directors, and/or Independent Contractors as additional compensation or in lieu of other compensation for Services to the Company, an Affiliate or Group Company. A Performance Unit is a hypothetical share of the value of the Company, represented by a notional account that the Company shall establish and maintain (or caused to be established or maintained) for such Participant who receives a grant of Performance Units. Performance Units shall be subject to such terms and conditions as the Committee, in its sole discretion, determines appropriate and sets forth in the Award Agreement including, without limitation, determining the performance goal or goals that, depending on the extent to which such goals are met, will determine the number and/or value of the Performance Units that will accrue to the Participant and any other Vesting criteria. Performance goals may be based on, without limitation, Company-wide, divisional and/or individual performance, as the Committee, in its sole discretion, may determine, and may be based on the performance measures listed in Section 12.3 below. The Committee shall determine and set forth in an Award Agreement whether a Participant who has been granted a Performance Unit shall also be entitled to a Dividend Equivalent Right.

Adjustment of Performance Goals. With respect to any Performance Shares or Performance Units that are not intended to qualify as Performance-Based Awards (as described in Section 12 below), the Committee shall have the authority at any time to adjust, as it deems necessary or desirable, the performance goals for any outstanding Performance Shares or Performance Units unless, at the time of establishment of such performance goals, the Committee precludes its authority to make such adjustments. Notwithstanding the foregoing, with respect to Awards intended to qualify as Performance-Based Awards (as defined below), the Committee shall not adjust such goals in a manner that would cause the Awards to no longer qualify as Performance-Based Awards.

Payout of Performance Shares or Performance Units. Subject to a Participant’s election to defer distribution in accordance with Section 18.4 below, upon the Vesting of a Performance Share or a Performance Unit, the shares of Common Stock representing the Performance Share or the cash value of the Performance Unit shall be distributed to the Participant, unless the Committee, in its sole discretion, determines to make the payment for the Performance Share in cash, or the Performance Unit in shares of Common Stock (or partly in cash and partly in shares of Common Stock) equal to the value of the shares of Common Stock or cash that would otherwise be distributed to the Participant.

In General. The Committee may, in its sole discretion, grant Cash Awards to Employees, Group Employees, Nonemployee Directors, and/or Independent Contractors as additional compensation or in lieu of other compensation for Services to the Company, an Affiliate or Group Company. A Cash Award shall be subject to such terms and conditions as the Committee, in its sole discretion, determines appropriate and sets forth in the Award Agreement including, without limitation, determining the Vesting Date with respect to such Cash Award, the criteria for the Vesting of such Cash Award, and the right of the Company to require the Participant to repay the Cash Award (with or without interest) upon termination of the Participant’s Service within specified periods.

Limitations. Each calendar year, an incentive pool equal to seven and one-half percent (7.5%) of the Company’s earnings before interest and taxes for the calendar year shall be created (the “Incentive Pool”) for the payment of Cash Awards that are intended to qualify as Performance-Based Awards (as described in Section 12 below). Each calendar year, the Committee shall allocate a percentage of the Incentive Pool to each Participant who is a Covered Employee for that year. In determining payouts under the Incentive Pool, (a) the percentage of the Incentive Pool allocated in any year may not exceed thirty percent (30%) of the total Incentive Pool to any single Covered Employee and (b) the aggregate payments to all Incentive Pool participants may not

Covered Employee. For purposes of the Plan, “Covered Employee” shall mean a Participant who, as of the date of Vesting and/or payout of an Award, or the date the Company or any of its Affiliates is entitled to a tax deduction as a result of the Award, as applicable, is one of the group of “covered employees,” as defined in the regulations promulgated under Code Section 162(m), or any successor statute.

In General. The Committee, in its sole discretion, may designate an Award granted under the Plan as a Performance-Based Award, which is an Award structured in a manner such that the compensation attributable to such Award is intended by the Committee to qualify as “performance-based compensation” (as such term is used in Code Section 162(m) and the Treasury Regulations thereunder) and thus be exempt from the deduction limitation imposed by Code Section 162(m).

Qualification of Performance-Based Awards. Awards shall qualify as Performance-Based Awards under the Plan only if:

at the time of grant the Committee is comprised solely of two or more “outside directors” (as such term is used in Code Section 162(m) and the Treasury Regulations thereunder);

with respect to either the granting or Vesting of an Award (other than (i) a Nonqualified Stock Option or (ii) a SAR, each of which are granted with an Exercise Price at or above the Fair Market Value of the Common Stock on the Award Date), such Award is subject to the achievement of a performance goal or goals based on one or more of the performance measures specified in Section 12.3 below;

the Committee establishes in writing (i) the objective performance-based goals applicable to a given performance period, and (ii) the individual Employees or class of Employees to which such performance-based goals apply no later than ninety (90) calendar days after the commencement of such performance period (but in no event after twenty-five percent (25%) of such performance period has elapsed);

no compensation attributable to a Performance-Based Award will be paid to or otherwise received by a Participant until the Committee certifies in writing that the performance goal or goals (and any other material terms) applicable to such performance period have been satisfied; and

after the establishment of a performance goal, the Committee shall not revise such performance goal (unless such revision will not disqualify compensation attributable to the Award as “performance-based compensation” under Code Section 162(m)) or increase the amount of compensation payable with respect to such Award upon the attainment of such performance goal.

Performance Measures. Performance measures shall be the pre-established objective goals established by the Committee for each performance period. The performance measures may be based upon the performance of the Company, of any Affiliate, or a division or unit thereof, or of an individual Participant, or groups of Participants, using one or more of the goals selected by the

Shareholder Reapproval. As required by Treasury Regulation Section 1.162-27(e)(vi), the material terms of performance goals as described in this Section 12 shall be disclosed to and reapproved by the Company’s shareholders no later than the first shareholder meeting that occurs in the 5^th year following the year in which the Company’s shareholders previously approved such performance goals.

Accelerated Vesting Upon Termination of Service. Unless the terms of an Award Agreement expressly provide otherwise, if there is a Change in Control of the Company, and, within two years following the Change in Control, the Company terminates a Participant’s Service other than for Cause or the Participant terminates Service for Good Reason, any outstanding Awards held by the Participant shall Vest. For this purpose, Good Reason will have the same meaning as such term or similar term is used in any employment, consulting, severance, or other written agreement between the Participant and the Company or an Affiliate. If there is no employment, consulting, or other written agreement between the Company or an Affiliate and the Participant or if such agreement does not define “Good Reason” or such similar term, then “Good Reason” will have the meaning specified in the Award Agreement; provided, that if the Award Agreement does not so specify, “Good Reason” will mean, as determined by the Committee in its sole discretion and solely with respect to this Plan and any Award made hereunder, the occurrence of any of the following events without the Participant’s express written consent:

The material reduction of the Participant’s authorities, duties, and position with the Company;

A reduction by the Company of the Participant’s base compensation by more than fifteen percent (15%), other than a reduction approved by the Board that similarly applies to all executive officers of the Company; or

A change in the offices of the Participant to a place that is more than thirty-five (35) miles in distance farther from the Participant’s home than the current executive offices of the Company in Oxford, MA.

Cashout. The Committee, in its sole discretion, may determine that, upon the occurrence of a Change in Control of the Company, all or a portion of certain outstanding Awards shall terminate within a specified number of days after notice to the holders, and each such holder shall receive an amount equal to the value of such Award on the date of the Change in Control, and with respect to each share of Common Stock subject to a Stock Option or SAR, an amount equal to the excess, if any, of the Fair Market Value of such shares of Common Stock immediately prior to the occurrence of such Change in Control of the Company over the Exercise Price per share of such Stock Option or SAR. Such amount shall be payable in cash, in one or more kinds of property (including the property, if any, payable in the transaction) or in a combination thereof, as the Committee, in its sole discretion, shall determine.

Assumption or Substitution of Awards. Notwithstanding anything contained in the Plan to the contrary, the Committee may, in its sole discretion, provide that an Award may be assumed by any entity that acquires control of the Company or may be substituted by a similar award under such entity’s compensation plans. If any entity that acquires control of the Company does not agree to assume outstanding Awards upon a Change in Control or replace such Awards with awards that preserve the existing value of the Award at the time of the Change in Control and provide for subsequent payout in accordance with the same Vesting schedule applicable to the original Awards, then, at the time of the Change in Control, (i) all outstanding Stock Options and SARs shall become immediately Vested and exercisable; (ii) all restrictions on Restricted Stock Awards and Stock Units shall immediately lapse; (iii) all performance goals other than with respect to performance-based Cash Awards shall be deemed achieved at target levels and all other terms and conditions met; (iv) all performance-based Cash Awards shall be paid out at target levels (or earned levels, if greater) and all other terms and conditions deemed met; and (v) all Performance Shares shall be delivered, and all Cash Awards, Performance Units and Stock Units shall be paid out as promptly as practicable.

Termination of Service Due to Death or Disability. Unless the terms of an Award Agreement expressly provide otherwise, if a Participant’s Service is terminated due to death all non-Vested portions of Awards held by the Participant on the date of the Participant’s death shall immediately Vest.

the end of the 12-month period following the date of the Participant’s death or Disability, or

the date the Stock Option or SAR would otherwise expire.

Termination of Service for Cause. Unless the terms of an Award Agreement expressly provide otherwise, if a Participant’s Service is terminated by the Company, the Affiliate or the Group Company, as the case may be, for Cause, all Awards held by the Participant on the date of the termination of Service, whether Vested or non-Vested, shall immediately be forfeited by the Participant as of such date. A Participant’s Service shall be deemed to have terminated for Cause if, after the Participant’s Service has terminated, facts and circumstances are discovered that would have justified a termination for Cause.

Other Terminations of Service. Unless the terms of an Award Agreement expressly provide otherwise, if a Participant’s Service is terminated for any reason other than for Cause or other than due to death or Disability:

all non-Vested portions of Awards held by the Participant on the date of the termination of his or her Service shall immediately be forfeited by such Participant as of such date; and

all Vested portions of Stock Options and/or SARs held by the Participant on the date of the termination of his or her Service shall remain exercisable until the earlier of (i) the end of the ninety (90) calendar day period following the date of the termination of the Participant’s Service or (ii) the date the Stock Option or SAR would otherwise expire.

ISOs. Notwithstanding anything contained in the Plan to the contrary, (i) the provisions contained in this Section 14 shall be applied to an ISO only if the application of such provision maintains the treatment of such ISO as an ISO.

NONEMPLOYEE DIRECTOR COMPENSATION

Annual Cash Retainer. Each Nonemployee Director will be paid a retainer fee for Service as a member of the Board (the “Annual Retainer”), in an amount that the Board will establish from time to time by resolution, in accordance with the IPG Photonics Corporation Non-Employee Director Compensation Plan (the “Director Compensation Plan”). In no event will the sum of the

Equity Awards. Each Nonemployee Director will be eligible to receive an Award upon appointment or election to the Board, and annually thereafter, in accordance with the Director Plan and subject to the limit in Section 6.1 and the terms of the applicable Award Agreement.

Withholding Taxes. With respect to Employees and Group Employees, the Company, or the applicable Affiliate or Group Company, may require a Participant who has Vested in his or her Restricted Stock Award, Stock Unit, Performance Share or Performance Unit granted hereunder, or who exercises a Stock Option or SAR granted hereunder, to reimburse the corporation that employs such Employee or Group Employee for any taxes required by any governmental regulatory authority to be withheld or otherwise deducted and paid by such corporation or entity in respect of the issuance or disposition of such shares or the payment of any amounts. In lieu thereof, the corporation that employs such Employee or Group Employee shall have the right to withhold the amount of such taxes from any other sums due or to become due from such corporation to the Employee or Group Employee upon such terms and conditions as the Committee shall prescribe. The corporation that employs the Employee or Group Employee may, in its discretion, hold the stock certificate to which such Employee or Group Employee is entitled upon the Vesting of a Restricted Stock Award, Stock Unit, Performance Share or Performance Unit or the exercise of a Stock Option or SAR as security for the payment of such withholding tax liability, until cash sufficient to pay that liability has been accumulated.

Use of Common Stock to Satisfy Withholding Obligation. With respect to Employees and Group Employees, at any time that the Company or an Affiliate or Group Company that employs such Employee or Group Employee becomes subject to a withholding obligation under applicable law with respect to the Vesting of a Restricted Stock Award, Stock Unit, Performance Share or Performance Unit or the exercise of a Nonqualified Stock Option (the “Tax Date”), except as set forth below, a holder of such Award may elect to satisfy, in whole or in part, the holder’s related personal tax liabilities (an “Election”) by (i) directing the Company, the Affiliate or the Group Company that employs such Employee or Group Employee to withhold from shares issuable in the related Vesting or exercise either a specified number of shares, or shares of Common Stock having a specified value in each case equal to the statutory personal withholding tax liabilities with respect to the applicable taxing jurisdiction, (ii) tendering shares of Common Stock previously issued pursuant to the exercise of a Stock Option or other shares of the Common Stock owned by the holder, or (iii) combining any or all of the foregoing Elections in any fashion. An Election shall be irrevocable. The withheld shares and other shares of Common Stock tendered in payment shall be valued at their Fair Market Value of the Common Stock on the Tax Date. The Committee may disapprove any Election, suspend or terminate the right to make Elections or provide that the right to make Elections shall not apply to particular shares or exercises. The Committee may impose any additional conditions or restrictions on the right to make an Election as it shall deem appropriate, including conditions or restrictions with respect to Section 16 of the Exchange Act.

No Guarantee of Tax Consequences. No person connected with the Plan in any capacity, including, but not limited to, the Company, an Affiliate or a Group Company and their directors, officers, agents and employees makes any representation, commitment, or guarantee that any tax treatment, including, but not limited to, federal, state and local income, estate and gift tax treatment, will be applicable with respect to amounts deferred under the Plan, or paid to or for the benefit of a Participant under the Plan, or that such tax treatment will apply to or be available to a Participant on account of participation in the Plan.

Termination of Plan. The Board may suspend or terminate the Plan at any time with or without prior notice; provided, however, that no action authorized by this Section 17.1 shall reduce the amount of any outstanding Award or change the terms and conditions thereof without the Participants’ consent, except as expressly provided herein.

Amendment of Plan. The Board may amend the Plan at any time with or without prior notice; provided, however, that no action authorized by this Section 17.2 shall reduce the amount of any outstanding Award or change the terms and conditions thereof without the Participants’ consent, except as expressly provided herein. No amendment of the Plan shall, without the approval of the shareholders of the Company:

increase the total number of shares of Common Stock that may be issued under the Plan;

increase the maximum number of shares with respect to all Awards measured in Common Stock that may be granted to any individual under the Plan;

increase the maximum dollar amount that may be paid with respect to all Awards measured in cash; or

modify the requirements as to eligibility for Awards under the Plan.

Amendment or Cancellation of Award Agreements. The Committee may amend or modify any Award Agreement at any time by mutual agreement between the Committee and the Participant or such other persons as may then have an interest therein; provided, however, that (i) no such amendment, modification, extension, cancellation, renewal, exchange, substitution or replacement will be to the detriment of a Participant with respect to any Award previously granted without the affected Participant’s written consent, (ii) any such amendment, modification, extension, cancellation, renewal exchange, substitution, or replacement must satisfy the requirements for exemption under Code Section 409A, and (iii) in no event will the Committee be permitted to, without the approval of the shareholders of the Company, (A) reduce the Exercise Price of any outstanding Stock Option or SAR, (B) exchange or replace an outstanding Stock Option or SAR with a new Stock Option or SAR with a lower Exercise Price, except pursuant to Section 5.2, or (C) cancel a Stock Option or SAR in exchange for cash or other Awards. In addition, by mutual agreement between the Committee and a Participant or such other persons as may then have an interest therein, Awards may be granted to an Employee, Group Employee, Nonemployee Director or Independent Contractor in substitution and exchange for, and in cancellation of, any Awards previously granted to such Employee, Group Employee, Nonemployee Director or Independent Contractor under the Plan, or any award previously granted to such Employee, Group Employee, Nonemployee Director or Independent Contractor under any other present or future plan of the Company or any present or future plan of an entity which (i) is purchased by the Company, (ii) purchases the Company, or (iii) merges into or with the Company.

Certain Amendments. Notwithstanding any provision in the Plan or in any Award Agreement to the contrary, the Board may amend the Plan without the consent of any Participant and the Committee may amend any Award Agreement without the consent of the Participant in order to comply with applicable law, including Code Sections 409A or 162(m), stock exchange listing standards, or accounting rules.

Other Provisions. Awards granted under the Plan may also be subject to such other provisions (whether or not applicable to an Award granted to any other Participant) as the Committee

Restrictive Covenants and Other Terms and Conditions. The Committee may provide, by way of the Award Agreement or otherwise, that, notwithstanding any other provision of this Plan to the contrary, if the Participant breaches the non-compete, non-solicitation, non-disclosure or other terms, conditions, restrictions and/or limitations of the Award Agreement, whether during or after termination of Service, in addition to any other penalties or restrictions that may apply under any employment agreement, consulting agreement, state law, or otherwise, the Participant will forfeit:

any and all Awards granted to him or her under the Plan, including Awards that have become Vested, shares of Common Stock that have been distributed to him or her, and the full value of shares of Common Stock that the Participant has sold (the Participant may be required to return such shares or repay the full value of such share of Common Stock to the Company); and/or

the profit the Participant has realized on the vesting or disposition of an Award granted to him or her under the Plan, including from exercise of any Stock Options, which is the difference between the Stock Options’ Exercise Price and the Fair Market Value of any Stock Option the Participant exercised (the Participant may be required to repay the profit and such difference to the Company).

Transferability. Each Award granted under the Plan to a Participant shall not be transferable other than by will or the laws of descent and distribution, and Stock Options and SARs shall be exercisable, during the Participant’s lifetime, only by the Participant. In the event of the death of a Participant, each Stock Option or SAR theretofore granted to him or her shall be exercisable during such period after his or her death as the Committee shall, in its sole discretion, set forth in the Award Agreement on the Award Date and then only by the executor or administrator of the estate of the deceased Participant or the person or persons to whom the deceased Participant’s rights under the Stock Option or SAR shall pass by will or the laws of descent and distribution. Notwithstanding the foregoing, the Committee, in its sole discretion, may permit the transferability of a Stock Option (other than an ISO) by a Participant solely to members of the Participant’s immediate family or trusts or family partnerships or other similar entities for the benefit of such persons, and subject to such terms, conditions, restrictions and/or limitations, if any, as the Committee may establish and include in the Award Agreement.

Election to Defer Compensation Attributable to Award. The Committee may, in its sole discretion and subject to Code Section 409A, allow a Participant to elect to defer the receipt of any compensation attributable to an Award under guidelines and procedures to be established by the Committee after taking into account the advice of the Company’s tax counsel.

Listing of Shares and Related Matters. If at any time the Committee shall determine that the listing, registration or qualification of the shares of Common Stock subject to an Award on any securities exchange or under any applicable law, or the consent or approval of any governmental regulatory authority, is necessary or desirable as a condition of, or in connection with, the granting of an Award or the issuance of shares of Common Stock thereunder, such Award may not be exercised, distributed or paid out, as the case may be, in whole or in part, unless such listing,

No Right, Title, or Interest in Company Assets. Participants shall have no right, title, or interest whatsoever in or to any investments that the Company may make to aid it in meeting its obligations under the Plan. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any Participant, beneficiary, legal representative or any other person. To the extent that any person acquires a right to receive payments from the Company under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company. All payments to be made hereunder shall be paid from the general funds of the Company, no special or separate fund shall be established, and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended.

No Right to Continued Employment or Service or to Grants. A Participant’s rights, if any, to continue to serve the Company, an Affiliate or a Group Company as a director, officer, Employee, independent contractor or otherwise, shall not be enlarged or otherwise affected by his or her designation as a Participant under the Plan, and the Company, the Affiliate and the Group Company reserve the right to terminate the employment or Service of any Employee or Group Employee or the Services of any Independent Contractor or director at any time. The adoption of the Plan shall not be deemed to give any Employee, Group Employee, Nonemployee Director, Independent Contractor or any other individual any right to be selected as a Participant or to be granted an Award.

Awards Subject to Foreign Laws. The Committee may grant Awards to individual Participants who are subject to the tax laws of nations other than the United States, and such Awards may have terms and conditions as determined by the Committee as necessary to comply with applicable foreign laws. The Committee may take any action that it deems advisable to obtain approval of such Awards by the appropriate foreign governmental entity; provided, however, that no such Awards may be granted pursuant to this Section and no action may be taken which would result in a violation of the Exchange Act or any other applicable law. The Committee may make such modifications, amendments, procedures, or sub-plans as may be necessary or advisable to comply with such legal or regulatory provisions. The Committee also may impose conditions on the exercise or Vesting of Awards in order to minimize the Company’s obligation with respect to tax equalization for Participants on assignments outside their home country.

Governing Law. The Plan, all Awards granted hereunder, and all actions taken in connection herewith shall be governed by and construed in accordance with the laws of the State of Delaware without reference to principles of conflict of laws, except as superseded by applicable federal law. Participants, the Company, a Group Company and Affiliate each submit and consent to the jurisdiction of the courts in the Commonwealth of Massachusetts, County of Worcester, including the Federal Courts located therein, should Federal jurisdiction requirements exist in any action brought to enforce (or otherwise relating to) this Plan or an Award Agreement.

Statute of Limitations for Claims Involving the Plan or Awards. If a Participant believes that the Committee has not followed his or her election, or the Participant believes that he or she has a claim against the Plan, the Company or Committee under the terms of the Plan or an Award Agreement, the Participant must file a written claim with the Committee within twelve (12) months after the Participant learned of the claim or allegedly made the election.

Other Agreements. Notwithstanding any provision of the Plan or an Award Agreement to the contrary, to the extent any employment, consulting, or other written agreement between the Participant and the Company, a Group Company or Affiliate provides Vesting terms or post-termination exercise periods with respect to an Award that are more favorable to the Participant

Other Benefits. No Award granted under the Plan shall be considered compensation for purposes of computing benefits under any retirement plan of the Company, an Affiliate or a Group Company nor affect any benefits or compensation under any other benefit or compensation plan of the Company, and Affiliate or a Group Company, now or subsequently in effect.

No Fractional Shares. No fractional shares of Common Stock shall be issued or delivered pursuant to the Plan or any Award. The Committee shall determine whether cash, Common Stock, Stock 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.

Electronic Delivery of Plan Information and Electronic Signatures. To the extent permitted by applicable law, the Company may deliver by email or other electronic means (including posting on a web site maintained by the Company or by a third party under contract with the Company) all documents relating to the Plan or any Award thereunder (including without limitation, prospectuses required by applicable securities law) and all other documents that the Company is required to deliver to its security holders (including without limitation, annual reports and proxy statements). To the extent permitted by applicable law, the Participant’s execution of an Award Agreement may be made by electronic facsimile or other method of recording of the Participant’s signature in a manner that is acceptable to the Committee.

Compliance With Code Section 409A. Any provision of the Plan that becomes subject to Code Section 409A will be interpreted and applied consistent with that Section and the applicable Treasury Regulations. Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Code Section 409A. If a Participant is a “specified employee” (as such term is defined for purposes of Code Section 409A) at the time of his or her termination of Service, no amount that is subject to Code Section 409A and that becomes payable by reason of such termination of Service shall be paid to the Participant before the earlier of (i) the expiration of the six (6) month period measured from the date of the Participant’s termination of Service, and (ii) the date of the Participant’s death. A termination of Service shall be deemed to occur only if it is a “separation from service” within the meaning of Code Section 409A, and references in the Plan and any Award Agreement to “termination,” “termination of employment,” or like terms shall mean a “separation from service.” A separation from Service shall be deemed to occur if it is anticipated that the level of Services the Participant will perform after a certain date (whether as an Employee or as an Independent Contractor) will permanently decrease to no more than twenty percent (20%) of the average level of Services provided by the Participant in the immediately preceding thirty-six (36) months. With respect to any Award that is or becomes subject to Code Section 409A, a Change in Control would only be deemed to have occurred only upon a change in control event described in Code Section 409A and Treasury Regulations §1.409A-3(i)(5).

Compensation Recovery Policy. Notwithstanding any provision in the Plan or in any Award Agreement to the contrary, Awards granted or paid under the Plan will be subject to any Compensation Recovery Policy established by the Company and amended from time to time.
