(a) any loss, cost, liability or expense (including attorneys’ fees) that may be imposed upon or incurred by such Covered Person in connection with or resulting from any action, suit or proceeding to which such Covered Person may be a party or in which such Covered Person may be involved by reason of any action taken or omitted to be taken under the Plan or any Award Agreement, in each case, in good faith; and

(b) any and all amounts paid by such Covered Person, with Orion’s approval, in settlement thereof, or paid by such Covered Person in satisfaction of any judgment in any such action, suit or proceeding against such Covered Person, provided that Orion will have the right, at its own expense, to assume and defend any such action, suit or proceeding and, once Orion gives notice of its intent to assume the defense, Orion will have sole control over such defense with counsel of Orion’s choice.

The foregoing right of indemnification will not be available to a Covered Person to the extent that a court of competent jurisdiction in a final judgment or other final adjudication, in either case, not subject to further appeal, determines that the acts or omissions of such Covered Person giving rise to the indemnification claim resulted from such Covered Person’s bad faith, fraud or willful misconduct. The foregoing right of indemnification will not be exclusive of any other rights of indemnification to which Covered Persons may be entitled under Orion’s Articles of Association, pursuant to any individual indemnification agreements between such Covered Person and the Company, as a matter of law, or otherwise, or any other power that Orion may have to indemnify such persons or hold them harmless.

Awards may be made under the Plan in the form of cash-based or stock-based Awards. Stock-based Awards may be in the form of any of the following, in each case in respect of Common Stock:

(a) stock options;

(b) stock appreciation rights;

(c) restricted shares;

(d) restricted stock units;

(e) dividend equivalent rights; and

(f) other equity-based or equity-related Awards (as further described in Section 2.8 ), that the Committee determines to be consistent with the purposes of the Plan and the interests of the Company.

1.6.1 Common Stock Subject to the Plan . Subject to the other provisions of this Section 1.6 , the total number of Shares that may be granted under the Plan shall be 2,145,000 (the “ Share Limit ”). Shares of Common Stock subject to awards that are assumed, converted or substituted under the Plan as a result of the Company’s acquisition of another company (including by way of merger, combination or similar transaction) (“ Acquisition Awards ”) will not count against the number of shares that may be granted under the Plan. Available shares under a stockholder approved plan of an acquired company (as appropriately adjusted to reflect the transaction) may be used for Awards under the Plan and do not reduce the maximum number of shares available for grant under the Plan, subject to applicable stock exchange requirements. No grants under the Plan shall be made at any time when (i) the authorized share capital of the Company or (ii) the distributable funds of the Company as determined in accordance with the laws of the Grand Duchy of Luxembourg are not sufficiently high in order to issue the number of Shares to be granted.

1.6.2 Replacement of Shares . Shares subject to an Award that is forfeited (including any restricted shares repurchased by the Company at the same price paid by the Grantee so that such Shares are returned to the Company), expires or is settled for cash (in whole or in part), to the extent of such forfeiture, expiration or cash settlement shall be available for future grants of Awards under the Plan and shall be added back in the same number of Shares as were deducted in respect of the grant of such Award. In the event that tax withholding obligations from an Award other than a stock option or stock appreciation right are satisfied by the withholding or tendering of shares of Common Stock, the shares so withheld or tendered shall be added back in the same number of Shares as were deducted in respect of the grant of such Award. The payment of dividend equivalent rights in cash in conjunction with any outstanding Awards shall not be counted against the Shares available for issuance under the Plan.

-8-

1.6.3 Adjustments . The Committee will (a) adjust the number of Shares authorized pursuant to Section 1.6.1 , (b) adjust the number of Shares set forth in Section 2.3.2 that can be issued through Incentive Stock Options and (c) adjust the terms of any outstanding Awards (including, without limitation, the number of Shares covered by each outstanding Award, the type of property to which the Award relates and the exercise or strike price of any Award), in such manner as it deems appropriate (including, without limitation, by payment of cash) to prevent the enlargement or dilution of rights, as a result of any increase or decrease in the number of issued Shares (or issuance of shares of stock other than Shares) resulting from a recapitalization, stock split, reverse stock split, stock dividend, spinoff, split-up, combination, reclassification or exchange of Shares, merger, consolidation, rights offering, separation, reorganization or liquidation, or any other change in the corporate structure or Shares, including any extraordinary dividend or extraordinary distribution; provided that no such adjustment shall be made if or to the extent that it would cause an outstanding Award to cease to be exempt from, or to fail to comply with, Section 409A of the Code.

ARTICLE II

AWARDS UNDER THE PLAN

2.1 Agreements Evidencing Awards

Each Award granted under the Plan will be evidenced by an Award Agreement that will contain such provisions and conditions as the Committee deems appropriate. Unless otherwise provided herein, the Committee may grant Awards in tandem with or, subject to Section 3.14 , in substitution for or satisfaction of any other Award or Awards granted under the Plan or any award granted under any other plan of the Company. By accepting an Award pursuant to the Plan, a Grantee thereby agrees that the Award will be subject to all of the terms and provisions of the Plan and the applicable Award Agreement.

2.2 No Rights as a Shareholder

No Grantee (or other person having rights pursuant to an Award) will have any of the rights of a shareholder of Orion with respect to Shares subject to an Award until the delivery of such Shares. Except as otherwise provided in Section 1.6.3 , no adjustments will be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, Common Stock, other securities or other property) for which the record date is before the date the Certificates for the Shares are delivered, or in the event the Committee elects to use another system, such as book entries by the transfer agent, before the date in which such system evidences the Grantee’s ownership of such Shares.

2.3 Options

2.3.1 Grant . Stock options may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

-9-

2.3.2 Incentive Stock Options . At the time of grant, the Committee will determine:

(a) whether all or any part of a stock option granted to an eligible Employee will be an Incentive Stock Option and

(b) the number of Shares subject to such Incentive Stock Option; provided , however , that

(1) the aggregate Fair Market Value (determined as of the time the option is granted) of the stock with respect to which Incentive Stock Options are exercisable for the first time by an eligible Employee during any calendar year (under all such plans of Orion and of any Subsidiary or parent corporation of Orion affiliate) will not exceed $100,000 and

(2) no Incentive Stock Option (other than an Incentive Stock Option that may be assumed or issued by the Company in connection with a transaction to which Section 424(a) of the Code applies) may be granted to a person who is not eligible to receive an Incentive Stock Option under the Code.

The form of any stock option which is entirely or in part an Incentive Stock Option will clearly indicate that such stock option is an Incentive Stock Option or, if applicable, the number of Shares subject to the Incentive Stock Option. No more than 2,145,000 Shares (as adjusted pursuant to the provisions of Section 1.6.3 ) that can be delivered under the Plan shall be issued through Incentive Stock Options.

2.3.3 Exercise Price . The exercise price per share with respect to each stock option will be determined by the Committee but, except as otherwise permitted by Section 1.6.3 , may never be less than the Fair Market Value of a share of Common Stock (or, in the case of an Incentive Stock Option granted to a Ten Percent Shareholder, 110% of the Fair Market Value). Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its closing price on the New York Stock Exchange on the date of grant of the Award of stock options.

2.3.4 Term of Stock Option . In no event will any stock option be exercisable after the expiration of 10 years (or, in the case of an Incentive Stock Option granted to a Ten Percent Shareholder, 5 years) from the date on which the stock option is granted.

2.3.5 Vesting and Exercise of Stock Option and Payment for Shares . A stock option may vest and be exercised at such time or times and subject to such terms and conditions as will be determined by the Committee at the time the stock option is granted and set forth in the Award Agreement. Subject to any limitations in the applicable Award Agreement, any Shares not acquired pursuant to the exercise of a stock option on the applicable vesting date may be acquired thereafter at any time before the final expiration of the stock option.

To exercise a stock option, the Grantee must give written notice to Orion specifying the number of Shares to be acquired and accompanied by payment of the full purchase price therefor in cash or by certified or official bank check or in another form as determined by the Company, which may include:

(a) personal check,

-10-

(b) Shares, based on the Fair Market Value as of the exercise date,

(c) any other form of consideration approved by the Company and permitted by applicable law, and

(d) any combination of the foregoing.

The Committee may also make arrangements for the cashless exercise of a stock option. Any person exercising a stock option will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by Orion on terms acceptable to Orion with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements. The Committee may, in its sole discretion, also take whatever additional actions it deems appropriate to effect such compliance, including, without limitation, placing legends on share certificates and issuing stop-transfer notices to agents and registrars. If a Grantee so requests, Shares acquired pursuant to the exercise of a stock option may be issued in the name of the Grantee and another jointly with the right of survivorship.

2.4 Stock Appreciation Rights

2.4.1 Grant . Stock appreciation rights may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

2.4.2 Exercise Price . The exercise price per share with respect to each stock appreciation right will be determined by the Committee but, except as otherwise permitted by Section 1.6.3 , may never be less than the Fair Market Value of the Common Stock. Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its closing price on the New York Stock Exchange on the date of grant of the Award of stock appreciation rights.

2.4.3 Term of Stock Appreciation Right . In no event will any stock appreciation right be exercisable after the expiration of 10 years from the date on which the stock appreciation right is granted.

2.4.4 Vesting and Exercise of Stock Appreciation Right and Delivery of Shares . Each stock appreciation right may vest and be exercised in such installments as may be determined in the Award Agreement at the time the stock appreciation right is granted. Subject to any limitations in the applicable Award Agreement, any stock appreciation rights not exercised on the applicable vesting date may be exercised thereafter at any time before the final expiration of the stock appreciation right.

To exercise a stock appreciation right, the Grantee must give written notice to Orion specifying the number of stock appreciation rights to be exercised. Upon exercise of stock appreciation rights, Shares, cash or other securities or property, or a combination thereof, as specified by the Committee, equal in value to:

(a) the excess of:

(1) the Fair Market Value of the Common Stock on the date of exercise over

-11-

(2) the exercise price of such stock appreciation right multiplied by

(b) the number of stock appreciation rights exercised that will be delivered to the Grantee.

Any person exercising a stock appreciation right will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by Orion on terms acceptable to Orion with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements. If a Grantee so requests, Shares purchased may be issued in the name of the Grantee and another jointly with the right of survivorship.

2.5 Restricted Shares

2.5.1 Grants . The Committee may grant or offer for sale restricted shares in such amounts and subject to such terms and conditions as the Committee may determine. Upon the delivery of such shares, the Grantee will have the rights of a shareholder with respect to the restricted shares, subject to any other restrictions and conditions as the Committee may include in the applicable Award Agreement. Each Grantee of an Award of restricted shares will be issued a Certificate in respect of such shares, unless the Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of such shares. In the event that a Certificate is issued in respect of restricted shares, such Certificate may be registered in the name of the Grantee, and shall, in addition to such legends required by applicable securities laws, bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Award, but will be held by Orion or its designated agent until the time the restrictions lapse.

2.5.2 Right to Vote and Receive Dividends on Restricted Shares . Each Grantee of an Award of restricted shares will, during the period of restriction, be the beneficial and record owner of such restricted shares and will have full voting rights with respect thereto. Unless the Committee determines otherwise in an Award Agreement, during the period of restriction, all dividends (whether ordinary or extraordinary and whether paid in cash, additional shares or other property) or other distributions paid upon any restricted share will be paid to the relevant Grantee.

2.6 Restricted Stock Units

The Committee may grant Awards of restricted stock units in such amounts and subject to such terms and conditions as the Committee may determine. A Grantee of a restricted stock unit will have only the rights of a general unsecured creditor of Orion, until delivery of Shares, cash or other securities or property is made as specified in the applicable Award Agreement. On the delivery date specified in the Award Agreement, the Grantee of each restricted stock unit not previously forfeited or terminated will receive one share of Common Stock, cash or other securities or property equal in value to a share of Common Stock or a combination thereof, as specified by the Committee.

-12-

2.7 Dividend Equivalent Rights

The Committee may include in the Award Agreement with respect to any Award a dividend equivalent right entitling the Grantee to receive amounts equal to all or any portion of the regular cash dividends that would be paid on the Shares covered by such Award if such shares had been delivered pursuant to such Award. The grantee of a dividend equivalent right will have only the rights of a general unsecured creditor of Orion until payment of such amounts is made as specified in the applicable Award Agreement. In the event such a provision is included in an Award Agreement, the Committee will determine whether such payments will be made in cash, in Shares or in another form, whether they will be conditioned upon the exercise of the Award to which they relate (subject to compliance with Section 409A of the Code), the time or times at which they will be made, and such other terms and conditions as the Committee will deem appropriate.

2.8 Other Stock-Based or Cash-Based Awards

The Committee may grant other types of equity-based, equity-related or cash-based Awards (including the grant or offer for sale of unrestricted shares of Common Stock) in such amounts and subject to such terms and conditions as the Committee may determine (including, without limitation, the achievement of performance goals). Such Awards may entail the transfer of actual Shares to Award recipients and may include Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.

2.9 Repayment If Conditions Not Met

If the Committee determines that all terms and conditions of the Plan and a Grantee’s Award Agreement were not satisfied, and that the failure to satisfy such terms and conditions is material, then the Grantee will be obligated to pay the Company immediately upon demand therefor, (a) with respect to a stock option and a stock appreciation right, an amount equal to the excess of the Fair Market Value (determined at the time of exercise) of the Shares that were delivered in respect of such exercised stock option or stock appreciation right, as applicable, over the exercise price paid therefor, (b) with respect to restricted shares, an amount equal to the Fair Market Value (determined at the time such shares became vested) of such restricted shares and (c) with respect to restricted stock units, an amount equal to the Fair Market Value (determined at the time of delivery) of the Shares delivered with respect to the applicable delivery date, in each case with respect to clauses (a), (b) and (c) of this Section 2.9 , without reduction for any amount applied to satisfy withholding tax or other obligations in respect of such Award.

-13-

3.1.2 Unless otherwise determined by the Board, shareholder approval of any suspension, discontinuance, revision or amendment will be obtained only to the extent necessary to comply with any applicable laws, regulations or rules of a securities exchange or self-regulatory agency; provided , however , if and to the extent the Board determines it is appropriate for the Plan to comply with the provisions of Section 422 of the Code, no amendment that would require shareholder approval under Section 422 of the Code will be effective without the approval of the shareholders of Orion.

3.2 Tax Withholding

Grantees shall be solely responsible for any applicable taxes (including, without limitation, income and excise taxes) and penalties, and any interest that accrues thereon, that they incur in connection with the receipt, vesting or exercise of any Award. As a condition to the delivery of any Shares, cash or other securities or property pursuant to any Award or the lifting or lapse of restrictions on any Award, or in connection with any other event that gives rise to a federal or other governmental tax withholding obligation on the part of the Company relating to an Award (including, without limitation, the Federal Insurance Contributions Act tax),

(a) the Company may deduct or withhold (or cause to be deducted or withheld) from any payment or distribution to a Grantee whether or not pursuant to the Plan (including Shares otherwise deliverable),

(b) the Committee will be entitled to require that the Grantee remit cash to the Company (through payroll deduction or otherwise), or

(c) the Company may enter into any other suitable arrangements to withhold, in each case in an amount not to exceed in the opinion of the Company the minimum amounts of such taxes required by law to be withheld.

3.3 Required Consents and Legends

3.3.1 If the Committee at any time determines that any Consent (as hereinafter defined) is necessary or desirable as a condition of, or in connection with, the granting of any Award, the delivery of Shares or the delivery of any cash, securities or other property under the Plan, or the taking of any other action thereunder (each such action, a “ Plan Action ”), then, subject to Section 3.14 , such Plan Action will not be taken, in whole or in part, unless and until such Consent will have been effected or obtained to the full satisfaction of the Committee. The Committee may direct that any Certificate evidencing Shares delivered pursuant to the Plan will bear a legend setting forth such restrictions on transferability as the Committee may determine to be necessary or desirable, and may advise the transfer agent to place a stop transfer order against any legended shares.

-14-

3.3.2 The term “ Consent ” as used in this Article III with respect to any Plan Action includes:

(a) any and all listings, registrations or qualifications in respect thereof upon any securities exchange or under any federal, state, or local law, or law, rule or regulation of a jurisdiction outside the United States;

(b) any and all written agreements and representations by the Grantee with respect to the disposition of Shares, or with respect to any other matter, which the Committee may deem necessary or desirable to comply with the terms of any such listing, registration or qualification or to obtain an exemption from the requirement that any such listing, qualification or registration be made;

(c) any and all other consents, clearances and approvals in respect of a Plan Action by any governmental or other regulatory body or any stock exchange or self-regulatory agency;

(e) any and all consents or authorizations required to comply with, or required to be obtained under, applicable local law or otherwise required by the Committee. Nothing herein will require the Company to list, register or qualify the Shares on any securities exchange.

3.4 Right of Offset

The Company will have the right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company pursuant to tax equalization, housing, automobile or other employee programs) that the Grantee then owes to the Company and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding the foregoing, if an Award provides for the deferral of compensation within the meaning of Section 409A of the Code, the Committee will have no right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement if such offset could subject the Grantee to the additional tax imposed under Section 409A of the Code in respect of an outstanding Award.

-15-

3.5 Nonassignability; No Hedging

Unless otherwise provided in an Award Agreement, no Award (or any rights and obligations thereunder) granted to any person under the Plan may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of or hedged, in any manner (including through the use of any cash-settled instrument), whether voluntarily or involuntarily and whether by operation of law or otherwise, other than by will or by the laws of descent and distribution, and all such Awards (and any rights thereunder) will be exercisable during the life of the Grantee only by the Grantee or the Grantee’s legal representative. Notwithstanding the foregoing, the Committee may permit, under such terms and conditions that it deems appropriate in its sole discretion, a Grantee to transfer any Award to any person or entity that the Committee so determines. Any sale, exchange, transfer, assignment, pledge, hypothecation or other disposition in violation of the provisions of this Section 3.5 will be null and void and any Award which is hedged in any manner will immediately be forfeited. All of the terms and conditions of the Plan and the Award Agreements will be binding upon any permitted successors and assigns.

3.6 Change in Control

3.6.1 The Committee may provide in any Award Agreement for provisions relating to a Change in Control, including, without limitation, the acceleration of the exercisability of, or the lapse of restrictions or deemed satisfaction of performance goals with respect to, any outstanding Awards.

3.6.2 In the event of a Change in Control, a Grantee’s Award shall be treated, to the extent determined by the Committee to be permitted under Section 409A, in accordance with one or more of the following methods as determined by the Committee in its sole discretion: (i) settle such Awards for an amount (as determined in the sole discretion of the Committee) of cash or securities, where in the case of stock options and stock appreciation rights, the value of such amount, if any, will be equal to the in-the-money spread value (if any) of such awards; (ii) provide for the assumption of or the issuance of substitute awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted under the Plan, as determined by the Committee in its sole discretion; (iii) modify the terms of such awards to add events, conditions or circumstances (including termination of employment within a specified period after a Change in Control) upon which the vesting of such Awards or lapse of restrictions thereon will accelerate; (iv) deem any performance conditions satisfied at target, maximum or actual performance through closing or provide for the performance conditions to continue (as is or as adjusted by the Committee) after closing; or (v) provide that for a period of at least 20 days prior to the Change in Control, any stock options or stock appreciation rights that would not otherwise become exercisable prior to the Change in Control will be exercisable as to all Shares subject thereto (but any such exercise will be contingent upon and subject to the occurrence of the Change in Control and if the Change in Control does not take place within a specified period after giving such notice for any reason whatsoever, the exercise will be null and void) and that any stock options or stock appreciation rights not exercised prior to the consummation of the Change in Control will terminate and be of no further force and effect as of the consummation of the Change in Control. For the avoidance of doubt, in the event of a Change in Control where all stock options and stock appreciation rights are settled for an amount (as determined in the sole discretion of the Committee) of cash or securities, the Committee may,

-16-

in its sole discretion, terminate any stock option or stock appreciation right for which the exercise price is equal to or exceeds the per share value of the consideration to be paid in the Change in Control transaction without payment of consideration therefor. Similar actions to those specified in this Section 3.6.2 may be taken in the event of a merger or other corporate reorganization that does not constitute a Change in Control.

3.7 Right of Discharge Reserved

Neither the grant of an Award nor any provision in the Plan or in any Award Agreement will confer upon any Grantee the right to continued Employment, or other engagement, by Orion or any Subsidiary or affect any right which Orion or any Subsidiary may have to terminate or alter the terms and conditions of such Employment or other engagement.

3.8 Nature of Payments

3.8.1 Any and all grants of Awards and deliveries of Common Stock, cash, securities or other property under the Plan will be in consideration of services performed or to be performed for Orion or any Subsidiary by the Grantee. Awards under the Plan may, in the discretion of the Committee, be made in substitution in whole or in part for cash or other compensation otherwise payable to a Grantee. Only whole Shares will be delivered under the Plan. Awards will, to the extent reasonably practicable, be aggregated in order to eliminate any fractional shares. Fractional shares may, in the discretion of the Committee, be forfeited or be settled in cash or otherwise as the Committee may determine.

3.8.2 All such grants and deliveries of Shares, cash, securities or other property under the Plan will constitute a special discretionary incentive payment to the Grantee, will not entitle the Grantee to the grant of any future Awards and will not be required to be taken into account in computing the amount of salary or compensation of the Grantee for the purpose of determining any contributions to or any benefits under any pension, retirement, profit-sharing, bonus, life insurance, severance or other benefit plan of the Company or under any agreement with the Grantee, unless the Company specifically provides otherwise.

3.9 Non-Uniform Determinations

3.9.1 The Committee’s determinations under the Plan and Award Agreements need not be uniform and any such determinations may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Committee will be entitled, among other things, to make non-uniform and selective determinations under Award Agreements, and to enter into non-uniform and selective Award Agreements, as to (a) the persons to receive Awards, (b) the terms and provisions of Awards and (c) whether a Grantee’s Employment has been terminated for purposes of the Plan.

3.9.2 To the extent the Committee deems it necessary, appropriate or desirable to comply with foreign law or practices and to further the purposes of the Plan, the Committee may, in its sole discretion and without amending the Plan, (i) establish special rules applicable to Awards to Grantees who are foreign nationals, are employed outside the United States or both

-17-

and grant Awards (or amend existing Awards) in accordance with those rules and (ii) cause Orion to enter into an agreement with any local Subsidiary pursuant to which such Subsidiary will reimburse the Company for the cost of such equity incentives.

3.10 Other Payments or Awards

Nothing contained in the Plan will be deemed in any way to limit or restrict the Company from making any award or payment to any person under any other plan, arrangement or understanding, whether now existing or hereafter in effect.

3.11 Plan Headings

The headings in the Plan are for the purpose of convenience only and are not intended to define or limit the construction of the provisions hereof.

3.12 Termination of Plan

The Board reserves the right to terminate the Plan at any time; provided , however , that, in any case, the Plan will terminate on the day before the 10 ^th anniversary of the Effective Date, and provided further , that all Awards made under the Plan before its termination will remain in effect until such Awards have been satisfied or terminated in accordance with the terms and provisions of the Plan and the applicable Award Agreements.

3.13 Clawback/Recapture Policy

Awards under the Plan shall be subject to the clawback or recapture policy, if any, that the Company may adopt from time to time to the extent provided in such policy and, in accordance with such policy, may be subject to the requirement that the Awards be repaid to the Company after they have been distributed to the Grantee.

3.14 Section 409A

3.14.1 All Awards made under the Plan that are intended to be “deferred compensation” subject to Section 409A shall be interpreted, administered and construed to comply with Section 409A, and all Awards made under the Plan that are intended to be exempt from Section 409A shall be interpreted, administered and construed to comply with and preserve such exemption. The Board and the Committee shall have full authority to give effect to the intent of the foregoing sentence. To the extent necessary to give effect to this intent, in the case of any conflict or potential inconsistency between the Plan and a provision of any Award or Award Agreement with respect to an Award, the Plan shall govern.

3.14.2 Without limiting the generality of Section 3.14.1 , with respect to any Award made under the Plan that is intended to be “deferred compensation” subject to Section 409A:

(a) any payment due upon a Grantee’s termination of employment shall be paid only upon such Grantee’s separation from service from the Company within the meaning of Section 409A;

-18-

(b) any payment to be made with respect to such Award in connection with the Grantee’s separation from service from the Company within the meaning of Section 409A (and any other payment that would be subject to the limitations in Section 409A(a)(2)(B) of the Code) shall be delayed until six months after the Grantee’s separation from service (or earlier death) in accordance with the requirements of Section 409A;

(c) to the extent necessary to comply with Section 409A, any other securities, other Awards or other property that the Company may deliver in lieu of Shares in respect of an Award shall not have the effect of deferring delivery or payment beyond the date on which such delivery or payment would occur with respect to the Shares that would otherwise have been deliverable (unless the Committee elects a later date for this purpose in accordance with the requirements of Section 409A);

(d) with respect to any required Consent described in Section 3.3 or the applicable Award Agreement, if such Consent has not been effected or obtained as of the latest date provided by such Award Agreement for payment in respect of such Award and further delay of payment is not permitted in accordance with the requirements of Section 409A, such Award or portion thereof, as applicable, will be forfeited and terminate notwithstanding any prior earning or vesting;

(e) if the Award includes a “series of installment payments” (within the meaning of Section 1.409A-2(b)(2)(iii) of the Treasury Regulations), the Grantee’s right to the series of installment payments shall be treated as a right to a series of separate payments and not as a right to a single payment;

(f) if the Award includes “dividend equivalents” (within the meaning of Section 1.409A-3(e) of the Treasury Regulations), the Grantee’s right to the dividend equivalents shall be treated separately from the right to other amounts under the Award; and

(g) for purposes of determining whether the Grantee has experienced a separation from service from the Company within the meaning of Section 409A, “subsidiary” shall mean a corporation or other entity in a chain of corporations or other entities in which each corporation or other entity, starting with Orion, has a controlling interest in another corporation or other entity in the chain, ending with such corporation or other entity. For purposes of the preceding sentence, the term “controlling interest” has the same meaning as provided in Section 1.414(c)-2(b)(2)(i) of the Treasury Regulations, provided that the language “at least 20 percent” is used instead of “at least 80 percent” each place it appears in Section 1.414(c)-2(b)(2)(i) of the Treasury Regulations.

-20-

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 Grantee. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended.

(4) reflect a change in the Grantee’s circumstances ( e.g ., a change in position, duties or responsibilities); and

(i) determine at any time whether, to what extent and under what circumstances and method or methods, subject to Section 3.14 ,

(1) Awards may be

(A) settled in cash, Shares, other securities, other Awards or other property (in which event, the Committee may specify what other effects such settlement will have on the Grantee’s Award, including the effect on any repayment provisions under the Plan or Award Agreement),

-5-

(B) exercised, or

(C) canceled, forfeited or suspended,

(2) Shares, other securities, other Awards or other property and other amounts payable with respect to an Award may be deferred either automatically or at the election of the Grantee thereof or of the Committee,

(3) to the extent permitted under applicable law, loans (whether or not secured by Common Stock) may be extended by the Company with respect to any Awards,

(4) Awards may be settled by Orion, any of its Subsidiaries or affiliates or any of their designees, and

(5) the exercise price for any stock option or stock appreciation right may be reset.

1.3.2 Actions of the Committee may be taken by the vote of a majority of its members present at a meeting (which may be held telephonically). Any action may be taken by a written instrument signed by a majority of the Committee members, and action so taken will be as fully effective as if it had been taken by a vote at a meeting. The determination of the Committee on all matters relating to the Plan or any Award Agreement will be final, binding and conclusive. The Committee may allocate among its members, and delegate to any person who is not a member of the Committee or to any administrative group within the Company, any of its powers, responsibilities or duties. Except as specifically provided to the contrary, references to the Committee include any administrative group, individual or individuals to whom the Committee has delegated its duties and powers.

1.3.3 Notwithstanding anything to the contrary contained herein, the Board may, in its sole discretion, at any time and from time to time, grant Awards or administer the Plan. In any such case, the Board will have all of the authority and responsibility granted to the Committee herein.

1.3.4 No member of the Board or regular, active employee and/or a prospective employee of Orion or any Subsidiary (each such person, a “ Covered Person ”) will have any liability to any person (including any Grantee) for any action taken or omitted to be taken or any determination made with respect to the Plan or any Award, except as expressly provided by statute. Each Covered Person will be indemnified and held harmless by Orion against and from:

(a) any loss, cost, liability or expense (including attorneys’ fees) that may be imposed upon or incurred by such Covered Person in connection with or resulting from any action, suit or proceeding to which such Covered Person may be a party or in which such Covered Person may be involved by reason of any action taken or omitted to be taken under the Plan or any Award Agreement, in each case, in good faith; and

(b) any and all amounts paid by such Covered Person, with Orion’s approval, in settlement thereof, or paid by such Covered Person in satisfaction of any judgment in any such action, suit or proceeding against such Covered Person, provided that Orion will have the right,

-6-

at its own expense, to assume and defend any such action, suit or proceeding and, once Orion gives notice of its intent to assume the defense, Orion will have sole control over such defense with counsel of Orion’s choice.

The foregoing right of indemnification will not be available to a Covered Person to the extent that a court of competent jurisdiction in a final judgment or other final adjudication, in either case, not subject to further appeal, determines that the acts or omissions of such Covered Person giving rise to the indemnification claim resulted from such Covered Person’s bad faith, fraud or willful misconduct. The foregoing right of indemnification will not be exclusive of any other rights of indemnification to which Covered Persons may be entitled under Orion’s Articles of Association, pursuant to any individual indemnification agreements between such Covered Person and the Company, as a matter of law, or otherwise, or any other power that Orion may have to indemnify such persons or hold them harmless.

1.4 Persons Eligible for Awards

Awards under the Plan may be made to Non-Employee Directors.

1.5 Types of Awards Under Plan

Awards may be made under the Plan in the form of cash-based or stock-based Awards. Stock-based Awards may be in the form of any of the following, in each case in respect of Common Stock:

(a) stock options;

(b) stock appreciation rights;

(c) restricted shares;

(d) restricted stock units;

(e) dividend equivalent rights; and

(f) other equity-based or equity-related Awards (as further described in Section 2.8 ), that the Committee determines to be consistent with the purposes of the Plan and the interests of the Company.

1.6 Shares of Common Stock Available for Awards

1.6.1 Common Stock Subject to the Plan . Subject to the other provisions of this Section 1.6 , the total number of Shares that may be granted under the Plan shall be 240,000 (the “ Share Limit ”). Aggregate Awards to Non-Employee Directors solely with respect to their service as Non-Employee Directors may not exceed the Shareholder Approval Limit in effect at any time based on the aggregate value of cash Awards and Fair Market Value of stock-based Awards, in each case, determined as of the date of grant. No grants under the Plan shall be made at any time when (i) the authorized share capital of the Company or (ii) the distributable funds of the Company as determined in accordance with the laws of the Grand Duchy of Luxembourg are not sufficiently high in order to issue the number of Shares to be granted.

-7-

1.6.2 Replacement of Shares . Shares subject to an Award that is forfeited (including any restricted shares repurchased by the Company at the same price paid by the Grantee so that such Shares are returned to the Company), expires or is settled for cash (in whole or in part), to the extent of such forfeiture, expiration or cash settlement shall be available for future grants of Awards under the Plan and shall be added back in the same number of Shares as were deducted in respect of the grant of such Award. In the event that tax withholding obligations from an Award other than a stock option or stock appreciation right are satisfied by the withholding or tendering of shares of Common Stock, the shares so withheld or tendered shall be added back in the same number of Shares as were deducted in respect of the grant of such Award. The payment of dividend equivalent rights in cash in conjunction with any outstanding Awards shall not be counted against the Shares available for issuance under the Plan.

1.6.3 Adjustments . The Committee will (a) adjust the number of Shares authorized pursuant to Section 1.6.1 and (b) adjust the terms of any outstanding Awards (including, without limitation, the number of Shares covered by each outstanding Award, the type of property to which the Award relates and the exercise or strike price of any Award), in such manner as it deems appropriate (including, without limitation, by payment of cash) to prevent the enlargement or dilution of rights, as a result of any increase or decrease in the number of issued Shares (or issuance of shares of stock other than Shares) resulting from a recapitalization, stock split, reverse stock split, stock dividend, spinoff, split-up, combination, reclassification or exchange of Shares, merger, consolidation, rights offering, separation, reorganization or liquidation, or any other change in the corporate structure or Shares, including any extraordinary dividend or extraordinary distribution; provided that no such adjustment shall be made if or to the extent that it would cause an outstanding Award to cease to be exempt from, or to fail to comply with, Section 409A of the Code.

ARTICLE II

AWARDS UNDER THE PLAN

2.1 Agreements Evidencing Awards

Each Award granted under the Plan will be evidenced by an Award Agreement that will contain such provisions and conditions as the Committee deems appropriate. Unless otherwise provided herein, the Committee may grant Awards in tandem with or, subject to Section 3.14 , in substitution for or satisfaction of any other Award or Awards granted under the Plan or any award granted under any other plan of the Company. By accepting an Award pursuant to the Plan, a Grantee thereby agrees that the Award will be subject to all of the terms and provisions of the Plan and the applicable Award Agreement.

2.2 No Rights as a Shareholder

No Grantee (or other person having rights pursuant to an Award) will have any of the rights of a shareholder of Orion with respect to Shares subject to an Award until the delivery of such Shares. Except as otherwise provided in Section 1.6.3 , no adjustments will be made for

-8-

dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, Common Stock, other securities or other property) for which the record date is before the date the Certificates for the Shares are delivered, or in the event the Committee elects to use another system, such as book entries by the transfer agent, before the date in which such system evidences the Grantee’s ownership of such Shares.

2.3 Options

2.3.1 Grant . Stock options may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

2.3.2 Exercise Price . The exercise price per share with respect to each stock option will be determined by the Committee but, except as otherwise permitted by Section 1.6.3 , may never be less than the Fair Market Value of a share of Common Stock. Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its closing price on the New York Stock Exchange on the date of grant of the Award of stock options.

2.3.3 Term of Stock Option . In no event will any stock option be exercisable after the expiration of 10 years from the date on which the stock option is granted.

2.3.4 Vesting and Exercise of Stock Option and Payment for Shares . A stock option may vest and be exercised at such time or times and subject to such terms and conditions as will be determined by the Committee at the time the stock option is granted and set forth in the Award Agreement. Subject to any limitations in the applicable Award Agreement, any Shares not acquired pursuant to the exercise of a stock option on the applicable vesting date may be acquired thereafter at any time before the final expiration of the stock option.

To exercise a stock option, the Grantee must give written notice to Orion specifying the number of Shares to be acquired and accompanied by payment of the full purchase price therefor in cash or by certified or official bank check or in another form as determined by the Company, which may include:

(a) personal check,

(b) Shares, based on the Fair Market Value as of the exercise date,

(c) any other form of consideration approved by the Company and permitted by applicable law, and

(d) any combination of the foregoing.

The Committee may also make arrangements for the cashless exercise of a stock option. Any person exercising a stock option will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by Orion on terms acceptable to Orion with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements. The Committee may, in its sole discretion, also take whatever additional actions it deems appropriate to effect such compliance, including, without limitation, placing legends on share certificates and issuing

-9-

stop-transfer notices to agents and registrars. If a Grantee so requests, Shares acquired pursuant to the exercise of a stock option may be issued in the name of the Grantee and another jointly with the right of survivorship.

2.4 Stock Appreciation Rights

2.4.1 Grant . Stock appreciation rights may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

2.4.2 Exercise Price . The exercise price per share with respect to each stock appreciation right will be determined by the Committee but, except as otherwise permitted by Section 1.6.3 , may never be less than the Fair Market Value of the Common Stock. Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its closing price on the New York Stock Exchange on the date of grant of the Award of stock appreciation rights.

2.4.3 Term of Stock Appreciation Right . In no event will any stock appreciation right be exercisable after the expiration of 10 years from the date on which the stock appreciation right is granted.

2.4.4 Vesting and Exercise of Stock Appreciation Right and Delivery of Shares . Each stock appreciation right may vest and be exercised in such installments as may be determined in the Award Agreement at the time the stock appreciation right is granted. Subject to any limitations in the applicable Award Agreement, any stock appreciation rights not exercised on the applicable vesting date may be exercised thereafter at any time before the final expiration of the stock appreciation right.

To exercise a stock appreciation right, the Grantee must give written notice to Orion specifying the number of stock appreciation rights to be exercised. Upon exercise of stock appreciation rights, Shares, cash or other securities or property, or a combination thereof, as specified by the Committee, equal in value to:

(a) the excess of:

(1) the Fair Market Value of the Common Stock on the date of exercise over

(2) the exercise price of such stock appreciation right multiplied by

(b) the number of stock appreciation rights exercised that will be delivered to the Grantee.

Any person exercising a stock appreciation right will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by Orion on terms acceptable to Orion with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements. If a Grantee so requests, Shares purchased may be issued in the name of the Grantee and another jointly with the right of survivorship.

-10-

2.5 Restricted Shares

2.5.1 Grants . The Committee may grant or offer for sale restricted shares in such amounts and subject to such terms and conditions as the Committee may determine. Upon the delivery of such shares, the Grantee will have the rights of a shareholder with respect to the restricted shares, subject to any other restrictions and conditions as the Committee may include in the applicable Award Agreement. Each Grantee of an Award of restricted shares will be issued a Certificate in respect of such shares, unless the Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of such shares. In the event that a Certificate is issued in respect of restricted shares, such Certificate may be registered in the name of the Grantee, and shall, in addition to such legends required by applicable securities laws, bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Award, but will be held by Orion or its designated agent until the time the restrictions lapse.

2.5.2 Right to Vote and Receive Dividends on Restricted Shares . Each Grantee of an Award of restricted shares will, during the period of restriction, be the beneficial and record owner of such restricted shares and will have full voting rights with respect thereto. Unless the Committee determines otherwise in an Award Agreement, during the period of restriction, all dividends (whether ordinary or extraordinary and whether paid in cash, additional shares or other property) or other distributions paid upon any restricted share will be paid to the relevant Grantee.

2.6 Restricted Stock Units

The Committee may grant Awards of restricted stock units in such amounts and subject to such terms and conditions as the Committee may determine. A Grantee of a restricted stock unit will have only the rights of a general unsecured creditor of Orion, until delivery of Shares, cash or other securities or property is made as specified in the applicable Award Agreement. On the delivery date specified in the Award Agreement, the Grantee of each restricted stock unit not previously forfeited or terminated will receive one share of Common Stock, cash or other securities or property equal in value to a share of Common Stock or a combination thereof, as specified by the Committee.

2.7 Dividend Equivalent Rights

The Committee may include in the Award Agreement with respect to any Award a dividend equivalent right entitling the Grantee to receive amounts equal to all or any portion of the regular cash dividends that would be paid on the Shares covered by such Award if such shares had been delivered pursuant to such Award. The grantee of a dividend equivalent right will have only the rights of a general unsecured creditor of Orion until payment of such amounts is made as specified in the applicable Award Agreement. In the event such a provision is included in an Award Agreement, the Committee will determine whether such payments will be made in cash, in Shares or in another form, whether they will be conditioned upon the exercise of the Award to which they relate (subject to compliance with Section 409A of the Code), the time or times at which they will be made, and such other terms and conditions as the Committee will deem appropriate.

-11-

2.8 Other Stock-Based or Cash-Based Awards

The Committee may grant other types of equity-based, equity-related or cash-based Awards (including retainers and meeting-based fees and the grant or offer for sale of unrestricted shares of Common Stock), in such amounts and subject to such terms and conditions as the Committee may determine (including, without limitation, the achievement of performance goals). Such Awards may entail the transfer of actual Shares to Award recipients and may include Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.

2.9 Repayment If Conditions Not Met

If the Committee determines that all terms and conditions of the Plan and a Grantee’s Award Agreement were not satisfied, and that the failure to satisfy such terms and conditions is material, then the Grantee will be obligated to pay the Company immediately upon demand therefor, (a) with respect to a stock option and a stock appreciation right, an amount equal to the excess of the Fair Market Value (determined at the time of exercise) of the Shares that were delivered in respect of such exercised stock option or stock appreciation right, as applicable, over the exercise price paid therefor, (b) with respect to restricted shares, an amount equal to the Fair Market Value (determined at the time such shares became vested) of such restricted shares and (c) with respect to restricted stock units, an amount equal to the Fair Market Value (determined at the time of delivery) of the Shares delivered with respect to the applicable delivery date, in each case with respect to clauses (a), (b) and (c) of this Section 2.9 , without reduction for any amount applied to satisfy withholding tax or other obligations in respect of such Award

ARTICLE III

MISCELLANEOUS

3.1 Amendment of the Plan

3.1.1 Unless otherwise provided in the Plan or in an Award Agreement, the Board may at any time and from time to time suspend, discontinue, revise or amend the Plan in any respect whatsoever but, subject to Sections 1.3 , 1.6.3 and 3.6 , no such amendment shall materially adversely impair the rights of the Grantee of any Award without the Grantee’s consent. Subject to Sections 1.3 , 1.6.3 and 3.6 , an Award Agreement may not be amended to materially adversely impair the rights of a Grantee without the Grantee’s consent.

3.1.2 Unless otherwise determined by the Board, shareholder approval of any suspension, discontinuance, revision or amendment will be obtained only to the extent necessary to comply with any applicable laws, regulations or rules of a securities exchange or self-regulatory agency.

3.2 Tax Withholding

Grantees shall be solely responsible for any applicable taxes (including, without limitation, income and excise taxes) and penalties, and any interest that accrues thereon, that they incur in connection with the receipt, vesting or exercise of any Award. As a condition to the delivery of any Shares, cash or other securities or property pursuant to any Award or the lifting or lapse of

-12-

restrictions on any Award, or in connection with any other event that gives rise to a federal or other governmental tax withholding obligation on the part of the Company relating to an Award (including, without limitation, the Federal Insurance Contributions Act tax),

(a) the Company may deduct or withhold (or cause to be deducted or withheld) from any payment or distribution to a Grantee whether or not pursuant to the Plan (including Shares otherwise deliverable),

(b) the Committee will be entitled to require that the Grantee remit cash to the Company (through payroll deduction or otherwise), or

(c) the Company may enter into any other suitable arrangements to withhold, in each case in an amount not to exceed in the opinion of the Company the minimum amounts of such taxes required by law to be withheld.

3.3 Required Consents and Legends

3.3.1 If the Committee at any time determines that any Consent (as hereinafter defined) is necessary or desirable as a condition of, or in connection with, the granting of any Award, the delivery of Shares or the delivery of any cash, securities or other property under the Plan, or the taking of any other action thereunder (each such action, a “ Plan Action ”), then, subject to Section 3.14 , such Plan Action will not be taken, in whole or in part, unless and until such Consent will have been effected or obtained to the full satisfaction of the Committee. The Committee may direct that any Certificate evidencing Shares delivered pursuant to the Plan will bear a legend setting forth such restrictions on transferability as the Committee may determine to be necessary or desirable, and may advise the transfer agent to place a stop transfer order against any legended shares.

3.3.2 The term “ Consent ” as used in this Article III with respect to any Plan Action includes:

(a) any and all listings, registrations or qualifications in respect thereof upon any securities exchange or under any federal, state, or local law, or law, rule or regulation of a jurisdiction outside the United States;

(b) any and all written agreements and representations by the Grantee with respect to the disposition of Shares, or with respect to any other matter, which the Committee may deem necessary or desirable to comply with the terms of any such listing, registration or qualification or to obtain an exemption from the requirement that any such listing, qualification or registration be made;

(c) any and all other consents, clearances and approvals in respect of a Plan Action by any governmental or other regulatory body or any stock exchange or self-regulatory agency;

-13-

(d) any and all consents by the Grantee to:

(1) the Company’s supplying to any third-party recordkeeper of the Plan such personal information as the Committee deems advisable to administer the Plan,

(2) the Company’s deducting amounts from the Grantee’s wages, or another arrangement satisfactory to the Committee, to reimburse the Company for advances made on the Grantee’s behalf to satisfy certain withholding and other tax obligations in connection with an Award,

(3) the Company’s imposing sales and transfer procedures and restrictions and hedging restrictions on Shares delivered under the Plan, and

(e) any and all consents or authorizations required to comply with, or required to be obtained under, applicable local law or otherwise required by the Committee. Nothing herein will require the Company to list, register or qualify the Shares on any securities exchange.

3.4 Right of Offset

The Company will have the right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company pursuant to tax equalization, housing, automobile or other programs) that the Grantee then owes to the Company and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding the foregoing, if an Award provides for the deferral of compensation within the meaning of Section 409A of the Code, the Committee will have no right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement if such offset could subject the Grantee to the additional tax imposed under Section 409A of the Code in respect of an outstanding Award.

3.5 Nonassignability; No Hedging

Unless otherwise provided in an Award Agreement, no Award (or any rights and obligations thereunder) granted to any person under the Plan may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of or hedged, in any manner (including through the use of any cash-settled instrument), whether voluntarily or involuntarily and whether by operation of law or otherwise, other than by will or by the laws of descent and distribution, and all such Awards (and any rights thereunder) will be exercisable during the life of the Grantee only by the Grantee or the Grantee’s legal representative. Notwithstanding the foregoing, the Committee may permit, under such terms and conditions that it deems appropriate in its sole discretion, a Grantee to transfer any Award to any person or entity that the Committee so determines. Any sale, exchange, transfer, assignment, pledge, hypothecation or other disposition in violation of the provisions of this Section 3.5 will be null and void and any Award which is hedged in any manner will immediately be forfeited. All of the terms and conditions of the Plan and the Award Agreements will be binding upon any permitted successors and assigns.

-14-

3.6 Change in Control

3.6.1 The Committee may provide in any Award Agreement for provisions relating to a Change in Control, including, without limitation, the acceleration of the exercisability of, or the lapse of restrictions or deemed satisfaction of performance goals with respect to, any outstanding Awards.

3.6.2 In the event of a Change in Control, a Grantee’s Award shall be treated, to the extent determined by the Committee to be permitted under Section 409A, in accordance with one or more of the following methods as determined by the Committee in its sole discretion: (i) settle such Awards for an amount (as determined in the sole discretion of the Committee) of cash or securities, where in the case of stock options and stock appreciation rights, the value of such amount, if any, will be equal to the in-the-money spread value (if any) of such awards; (ii) provide for the assumption of or the issuance of substitute awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted under the Plan, as determined by the Committee in its sole discretion; (iii) modify the terms of such awards to add events, conditions or circumstances (including termination of directorship within a specified period after a Change in Control) upon which the vesting of such Awards or lapse of restrictions thereon will accelerate; (iv) deem any performance conditions satisfied at target, maximum or actual performance through closing or provide for the performance conditions to continue (as is or as adjusted by the Committee) after closing; or (v) provide that for a period of at least 20 days prior to the Change in Control, any stock options or stock appreciation rights that would not otherwise become exercisable prior to the Change in Control will be exercisable as to all Shares subject thereto (but any such exercise will be contingent upon and subject to the occurrence of the Change in Control and if the Change in Control does not take place within a specified period after giving such notice for any reason whatsoever, the exercise will be null and void) and that any stock options or stock appreciation rights not exercised prior to the consummation of the Change in Control will terminate and be of no further force and effect as of the consummation of the Change in Control. For the avoidance of doubt, in the event of a Change in Control where all stock options and stock appreciation rights are settled for an amount (as determined in the sole discretion of the Committee) of cash or securities, the Committee may, in its sole discretion, terminate any stock option or stock appreciation right for which the exercise price is equal to or exceeds the per share value of the consideration to be paid in the Change in Control transaction without payment of consideration therefor. Similar actions to those specified in this Section 3.6.2 may be taken in the event of a merger or other corporate reorganization that does not constitute a Change in Control.

3.7 Right of Discharge Reserved

Neither the grant of an Award nor any provision in the Plan or in any Award Agreement will (1) confer upon any Grantee the right to remain in the service of Orion as a Non-Employee Director or affect any right which Orion or any Subsidiary may have to terminate or alter the terms and conditions of such service or (2) create any obligation on behalf of the Board to nominate any Non-Employee Director for re-election to the Board by Orion’s shareholders.

-15-

3.8 Nature of Payments

3.8.1 Any and all grants of Awards and deliveries of Common Stock, cash, securities or other property under the Plan will be in consideration of services performed or to be performed for Orion or any Subsidiary by the Grantee. Awards under the Plan may, in the discretion of the Committee, be made in substitution in whole or in part for cash or other compensation otherwise payable to a Grantee. Only whole Shares will be delivered under the Plan. Awards will, to the extent reasonably practicable, be aggregated in order to eliminate any fractional shares. Fractional shares may, in the discretion of the Committee, be forfeited or be settled in cash or otherwise as the Committee may determine.

3.8.2 All such grants and deliveries of Shares, cash, securities or other property under the Plan will constitute a special discretionary incentive payment to the Grantee, will not entitle the Grantee to the grant of any future Awards and will not be required to be taken into account in computing the amount of salary or compensation of the Grantee for the purpose of determining any contributions to or any benefits under any pension, retirement, profit-sharing, bonus, life insurance, severance or other benefit plan of the Company or under any agreement with the Grantee, unless the Company specifically provides otherwise.

3.9 Non-Uniform Determinations

3.9.1 The Committee’s determinations under the Plan and Award Agreements need not be uniform and any such determinations may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Committee will be entitled, among other things, to make non-uniform and selective determinations under Award Agreements, and to enter into non-uniform and selective Award Agreements, as to (a) the persons to receive Awards, (b) the terms and provisions of Awards and (c) whether a Grantee’s has separated from service for purposes of the Plan.

3.9.2 To the extent the Committee deems it necessary, appropriate or desirable to comply with foreign law or practices and to further the purposes of the Plan, the Committee may, in its sole discretion and without amending the Plan, (i) establish special rules applicable to Awards to Grantees who are foreign nationals, are employed outside the United States or both and grant Awards (or amend existing Awards) in accordance with those rules and (ii) cause Orion to enter into an agreement with any local Subsidiary pursuant to which such Subsidiary will reimburse the Company for the cost of such equity incentives.

3.10 Other Payments or Awards

Nothing contained in the Plan will be deemed in any way to limit or restrict the Company from making any award or payment to any person under any other plan, arrangement or understanding, whether now existing or hereafter in effect.

3.11 Plan Headings

The headings in the Plan are for the purpose of convenience only and are not intended to define or limit the construction of the provisions hereof.

-16-

3.12 Termination of Plan

The Board reserves the right to terminate the Plan at any time; provided , however , that, in any case, the Plan will terminate on the day before the 10 ^th anniversary of the Effective Date, and provided further , that all Awards made under the Plan before its termination will remain in effect until such Awards have been satisfied or terminated in accordance with the terms and provisions of the Plan and the applicable Award Agreements.

3.13 Clawback/Recapture Policy

Awards under the Plan shall be subject to the clawback or recapture policy, if any, that the Company may adopt from time to time to the extent provided in such policy and, in accordance with such policy, may be subject to the requirement that the Awards be repaid to the Company after they have been distributed to the Grantee.

3.14 Section 409A

3.14.1 All Awards made under the Plan that are intended to be “deferred compensation” subject to Section 409A shall be interpreted, administered and construed to comply with Section 409A, and all Awards made under the Plan that are intended to be exempt from Section 409A shall be interpreted, administered and construed to comply with and preserve such exemption. The Board and the Committee shall have full authority to give effect to the intent of the foregoing sentence. To the extent necessary to give effect to this intent, in the case of any conflict or potential inconsistency between the Plan and a provision of any Award or Award Agreement with respect to an Award, the Plan shall govern.

3.14.2 Without limiting the generality of Section 3.14.1 , with respect to any Award made under the Plan that is intended to be “deferred compensation” subject to Section 409A:

(a) any payment due upon a Grantee’s ceasing to provide services to the Company shall be paid only upon such Grantee’s separation from service from the Company within the meaning of Section 409A;

(b) any payment to be made with respect to such Award in connection with the Grantee’s separation from service from the Company within the meaning of Section 409A (and any other payment that would be subject to the limitations in Section 409A(a)(2)(B) of the Code) shall be delayed until six months after the Grantee’s separation from service (or earlier death) in accordance with the requirements of Section 409A;

(c) to the extent necessary to comply with Section 409A, any other securities, other Awards or other property that the Company may deliver in lieu of Shares in respect of an Award shall not have the effect of deferring delivery or payment beyond the date on which such delivery or payment would occur with respect to the Shares that would otherwise have been deliverable (unless the Committee elects a later date for this purpose in accordance with the requirements of Section 409A);

(d) with respect to any required Consent described in Section 3.3 or the applicable Award Agreement, if such Consent has not been effected or obtained as of the latest

-17-

date provided by such Award Agreement for payment in respect of such Award and further delay of payment is not permitted in accordance with the requirements of Section 409A, such Award or portion thereof, as applicable, will be forfeited and terminate notwithstanding any prior earning or vesting;
