PURPOSE OF PLAN

The purpose of the Plan shall be to provide tax-deferred savings and employer contributions to eligible employees of the Employer and to their beneficiaries.

Such contributions, and any income derived therefrom, shall be held for the exclusive benefit of the participating employees and their beneficiaries and shall not be used for, or diverted to, any other purpose. This Plan is intended to satisfy the applicable requirements of Section 401 of the Code as a profit sharing plan with a cash or deferred feature. The Plan also is intended to reflect certain provisions of the Economic Growth and Tax Reconciliation Act of 2001 (“EGTRRA”); the Pension Protection Act of 2006 (“PPA”); the Heroes Earnings Assistance and Relief Tax Act of 2008 (“HEART”); the Worker, Retiree, and Employer Recovery Act of 2008 (“WRERA”); and other applicable laws and should be construed in accordance with these laws and guidance issued thereunder.

increases) and was in the top-paid group of Employees for such preceding year. The term Highly Compensated Employee also includes Employees who are five-percent (5%) owners at any time during the Determination Year. The Determination Year shall be the Plan Year and the Look-back Year shall be the twelve (12) month period immediately preceding the Determination Year. An Employee is in the top-paid group of Employees for any year if such Employee is in the group consisting of the top twenty percent (20%) of the Employees when ranked on the basis of compensation paid during such year. For purposes of this Section 2.30, compensation shall mean compensation as defined under Section 415(c)(3) of the Code paid to the Employee by the Employer, including any Elective Contributions made under the Plan and any salary reduction contributions under any other plan of the Employer. The determination of who is a Highly Compensated Employee will be made in accordance with section 414(q) of the Code and the regulations thereunder.

2.31 Hour of Service means: Each hour for which an Employee is directly or indirectly paid or entitled to payment for the performance of duties for an Employer; these hours shall be credited to the computation period in which the duties are performed, and

(a) Each hour for which an Employee is directly or indirectly paid or entitled to payment by the Employer on account of a period of time during which no duties are performed (irrespective of whether the employment relationship has terminated) due to vacation, holiday, illness, incapacity, disability, layoff, jury duty, military duty or leave of absence including each hour for which an Employee receives severance pay; except that

(1) not more than five hundred and one (501) Hours of Service shall be credited in each single computation period during which the Employee performs no duties (whether or not such period occurs in a single computation period) and

(2) Hours of Service shall not be counted where such payment is made or is due:

(i) under a plan maintained solely for the purpose of complying with applicable workmen’s compensation, unemployment or disability insurance laws, or

(ii) solely to reimburse an Employee for medical or medically related expenses; (hours credited under this Paragraph (b) shall be credited to the computation period(s) in which the period during which no duties were performed occurred), and

(b) Each hour for which back pay, irrespective of payment due to mitigation of damages, is either awarded or agreed to by the Employer; these hours shall be credited to the computation period(s) to which the award or agreement for back pay pertains rather than to the computation period in which the award, agreement or payment is made; provided, however, that the limits under Paragraph (b) above are applicable and that an Employee shall not be entitled to additional Hours of Service under this Paragraph (c) for the same Hours of Service credited under Paragraph (a) or (b) above.

(c) For purposes of determining whether a One-Year Break in Service has occurred for participation and vesting purposes, an individual must be credited with service up to a total of no more than 501 Hours of Service for certain periods of absence from work. This rule applies to an individual who is absent from work by reason of:

(1) pregnancy of the individual

(2) birth of a child of the individual

(3) placement of a child in connection with the adoption of the child by the individual, or

(4) caring for the child during the period immediately following the birth or placement for adoption.

The Hours of Service required to be credited under this provision are the Hours of Service which otherwise would normally have been credited to the Employee but for such absence, or in any case where the Administrator is unable to determine such hours, eight (8) Hours of Service per day of absence. Any hours to which the Employee shall be entitled must be credited only (a) in the Plan Year in which the absence begins for one of the reasons, if the crediting is necessary to prevent a One-Year Break in Service in that year, or, if the Employee already has 501 hours in such year, (b) in the following Plan Year.

If the absence from work is not an approved leave of absence, credit will not be granted during such absence unless the Employee informs the Employer on a timely basis that the leave was taken for one of the permitted reasons listed above.

Hours of Service hereunder shall be calculated and credited in a manner consistent with Department of Labor Regulation Sections 2530.200b-2(b) and (c), which are incorporated by reference hereunder.

In the case of Hours of Service to be credited to an Employee in connection with a period of no more than thirty-one (31) days which extends beyond one computation period, all such Hours of Service may be credited to the first computation period or the second computation period in a manner applied consistently with respect to all Employees within reasonably defined job classifications.

In determining Hours of Service for the purposes of determining an Employee’s eligibility to participate in the Plan and the vesting of benefits, the term “Employer” shall include any other corporation which is a member of a controlled group of corporations (determined in accordance with Section 414(b) of the Code) of which the Employer is a member, and any other trade or business (whether or not incorporated) which is under common control with the Employer; but only for the period during which such other corporation and the Employer are members of such controlled group of corporations or are under common control.

For purposes of determining an Employee’s eligibility to participate in the Plan and vesting of benefits, an Hour of Service shall also include an Hour of Service with a company heretofore or hereafter merged or consolidated or otherwise absorbed by an Employer,

or all or a substantial part of the assets or business of which have been or shall be acquired by an Employer (hereafter, “Predecessor Company”):

(i) if the Employer continues to maintain an employee benefit plan of such Predecessor Company (hereinafter “Predecessor Plan”); or

(ii) if, and to the extent, such employment with the Predecessor Company is required to be treated as employment with the Employer under regulations prescribed by the Secretary of the Treasury; or

(iii) if, and to the extent, approved by the Board in its sole discretion effected on a nondiscriminatory basis as to all persons similarly situated.

(d) Each hour to the extent and for the purpose it is required to be counted under the Family and Medical Leave Act.

2.32 Investment Fund(s) shall mean one or more of the investment media offered through the Trustee as an investment alternative vehicle for contributions to the Plan. The Committee shall have the exclusive authority to select the Investment Fund(s) available for investment under the Plan.

2.33 Key Employee shall mean an Employee or former Employee (including any deceased Employee) who at any time during the Plan Year containing the Determination Date for the Plan Year in question was an officer of the Employer or an Affiliated Employer having annual compensation greater than $130,000 (as adjusted under Section 416(i)(1) of the Code for Plan Years beginning after December 31, 2002), a five percent (5%) owner of the Employer or an Affiliate, or a one percent (1%) owner of the Employer or an Affiliated Employer and the recipient of annual compensation in excess of one hundred and fifty thousand dollars ($150,000).

For this purpose, annual compensation means compensation within the meaning of Section 415(c)(3) of the Code.

(a) he or she becomes employed by the Employer and, upon employment, is scheduled to work 1,000 Hours of Service during a 12-consecutive month period; or

(b) he or she is credited with one (1) Year of Participation Service under the Plan.

Notwithstanding the foregoing, any Eligible Employee who, upon hire, is not scheduled to work 1,000 Hours of Service during a 12-consecutive month period but who, prior to the date such Eligible Employee commences participation in the Plan, changes his or her employment status so that the Eligible Employee is scheduled to work 1,000 Hours of Service during a 12-consecutive month period shall commence participation in the Plan as of the date of such change in status.

3.2 Re-employment and Leaves of Absence. A Former Participant or a former Eligible Employee who returns to employment and becomes a Covered Employee may commence participation on the date he or she becomes a Covered Employee. An employee who has satisfied the eligibility requirements of this Article III but does not become a Participant due to a One Year Break in Service, a Leave of Absence or because he or she is not a Covered Employee may commence participation on the first day of the payroll period that begins next following the termination of the One Year Break in Service or Leave of Absence or the date he or she again becomes a Covered Employee.

3.3 Notice of Eligibility. The Plan Administrator shall notify each Employee of his or her status as an Eligible Employee and right to participate in the Plan.

Each Eligible Employee, including any Rehired Employee, who wishes to participate in the Plan shall be required, after receipt of notification from the Employer of his or her status as an Eligible Employee, to file an election to participate in a manner prescribed by the Employer. The Eligible Employee will become a Participant as soon as administratively feasible on or after the date of the filing of an election to participate.

(b) Rehired Employee. For purposes of this Section, “Rehired Employee” shall mean any Employee who Terminates Employment and subsequently recommences employment.

3.5 Automatic Salary Reduction Contributions. Notwithstanding the provisions of this

Article III to the contrary, each Eligible Employee who is first hired by the Employer effective on or after August 1, 2008 shall be automatically enrolled in the Plan effective 60 days following the later of (i) the Eligible Employee’s date of hire or (ii) the Eligible Employee’s twenty-first (21st) birthday. A Participant who is enrolled in the Plan pursuant to the provisions of this Section 3.5, notwithstanding any contrary provisions in Article IV hereof, shall be deemed to have elected an Elective Contribution rate of 3% of his or her Compensation (5% of Compensation for those hired on or after October 1, 2011) unless such Participant elects a different percentage, or elects not to participate in the Plan, in accordance with procedures established by the Committee from time to time. Notwithstanding the foregoing, the Committee or its designee shall provide each Eligible Employee with a written notice describing the effect of the automatic contributions provided for in this Section 3.5 prior to the first payroll period for which such automatic contributions are to be in effect with respect to each such Eligible Employee. The Committee or its designee also shall provide each Eligible Employee with a reasonable period of time to submit an election prior to the implementation of the first automatic contributions described in this Section 3.5. Notwithstanding the fifteen (15) day notice requirement in Section 8.7 to the contrary, any such election shall be effective immediately upon the Committee’s receipt of the election and shall continue to be in effect until an Eligible Employee or a Participant submits a subsequent election. Annually, the Committee or its designee shall provide the Participants subject to such automatic contributions with a written notice of the application of the automatic contributions.

ARTICLE IV

EMPLOYEE CONTRIBUTIONS

4.1 Elective and Employee Contribution. Each Participant may contribute through payroll deductions to the Plan commencing on the date he or she enters the Plan pursuant to Section 3.4 or Section 3.5 hereof a percentage of his or her Compensation subject to such limits as the Plan Administrator may specify. During any taxable year, a Participant’s Elective Contributions may not exceed the dollar limitation contained in Section 402(g) of the Code in effect for such taxable year. In addition, each Participant also may make Employee Contributions in such manner, at such time and in such amounts as the Plan Administrator may specify.

4.2 Distribution of Excess Elective Contributions. The Committee may, in its sole discretion, distribute any Elective Contributions in excess of the dollar limitation contained in Section 402(g) of the Code, plus investment gain or loss, to the Participant no later than April 15 of the calendar year immediately following the calendar year in which the excess occurred. The Plan Administrator is deemed to have received notice of excess Elective Contributions from the Participant to the extent Elective Contributions from this Plan and any other plans maintained by the Employer exceed the limit under Section 402(g). Further, if the Participant provides satisfactory evidence to demonstrate that all contributions by the Participant, in this Plan and any other qualified plan(s), exceed the applicable limit, then the Plan Administrator may, in its

sole discretion, distribute sufficient contributions from this Plan to allow the Participant to comply with the applicable annual limit. The Plan may use any reasonable method for computing the income or loss allocable to excess Elective Contributions, provided that the method does not violate Code Section 401(a)(4), is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to Participants’ accounts. Alternatively, the Plan may elect to use a method of allocating Plan Year or gap period income specified under Treasury Regulation Section 1.401(k)-2(b)(2)(iv). Notwithstanding anything to the contrary, effective for the Plan Year beginning on January 1, 2007, distributions shall include gap period income allocable to excess Elective Contributions up through the date of distribution. Effective for Plan Years beginning on and after January 1, 2008, distributions shall only include income allocable to excess Elective Contributions through the end of the tax year for which such contributions were made.

4.3 Changing Elective Contribution Elections. Elective Contributions shall continue to be made for each Participant at the rate elected until the Participant changes or revokes his or her election with such prior notice as the Plan Administrator may prescribe and as of such time or times as the Plan Administrator may prescribe. Elective Contributions will commence (or recommence) at such times as the Plan Administrator may prescribe.

4.4 Investment of Elective Contributions. Elective Contributions and Employee Contributions shall be invested in the manner prescribed under Sections 8.5, 8.6 and 8.7.

4.5 Actual Deferral Percentage Testing Requirements.

(a) Reduction of Elective Contributions. If at any time the Plan Administrator determines that the Plan may not satisfy the actual deferral percentage tests of Section 401(k)(3) of the Code and any guidance issued by the Internal Revenue Service regarding Code Section 401(k)(3), as defined in Section 4.5(b) hereafter, then the Plan Administrator may, in its discretion, reduce the elected Elective Contributions of any Highly Compensated Employee to the extent necessary to ensure, within a reasonable margin of safety, that the tests will be satisfied. The Plan Administrator may accomplish this reduction by any method or combination of methods including, without limitation, the reduction of the otherwise applicable Compensation against which the elected rate of contributions is applied, the reduction of the rate of contribution for any Highly Compensated Employee, or the setting of a maximum amount of contribution for any Highly Compensated Employee. Such reductions or limitations shall be effective only for purposes of this Section 4.5, except as may be directed otherwise by the Plan Administrator. However, no such reductions or limitations shall discriminate against any Employee who is relatively less highly compensated.

Notwithstanding any provisions of this Section 4.5 to the contrary, if after the close of the Plan Year the Committee determines that the Plan does not satisfy the actual deferral percentage test of Section 401(k)(3), as defined in Section 4.5(b) hereafter, then the Plan Administrator shall reduce the Elective Contributions of Highly Compensated Employees, to the extent necessary to satisfy the actual deferral percentage test, in accordance with the terms of this paragraph. First, the Highly Compensated (or Highly Compensated Employees if more than one has the same amount of Elective Contributions) with the highest Elective Contributions shall have his or her Elective Contributions reduced until his or her Elective Contributions equals the

Elective Contributions of the Highly Compensated Employee(s) with the next highest Elective Contributions; provided that a lesser reduction shall be appropriate if such lesser reduction would equal the total excess contributions computed under this Section. If the total excess contributions are not distributed by this initial reduction, then the Highly Compensated Employees with the highest Elective Contributions shall have their Elective Contributions reduced until their Elective Contributions equal the Elective Contributions of the Highly Compensated Employee(s) with the next highest Elective Contributions; provided that a lesser reduction shall be appropriate if such lesser reduction would equal the total excess contributions computed under this Section. Such reductions shall continue in the same manner until the total excess contributions have been distributed. If any monies are distributed in accordance with this Section 4.5, any income allocable thereto for such Plan Year and for the period between the close of the Plan Year and the date of distribution shall be distributed to the appropriate Highly Compensated Employees. Notwithstanding any other provision of the Plan, any excess contributions, and income allocable thereto, shall be distributed in accordance with this Section 4.5 no later than the last day of each Plan Year to Highly Compensated Employees to whose Plan Accounts such excess contributions were allocated for the preceding Plan Year.

The Plan may use any reasonable method for computing the income or loss allocable to excess Elective Contributions, provided that the method does not violate Code Section 401(a)(4), is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to Participants’ accounts. Alternatively, the Plan may elect to use a method of allocating Plan Year or gap period income specified under Treasury Regulation Section 1.401(k)-2(b)(2)(iv). Notwithstanding the foregoing, effective for Plan Years beginning on and after January 1, 2008, gap period income will not be included when making distributions of excess Elective Contributions.

(b) Actual Deferral Percentage Test. For purposes of Section 4.5 “actual deferral percentage test” shall mean a test that is satisfied if either one of the following two tests are satisfied: (1) the actual deferral percentage for the Highly Compensated Employees is not more than the actual deferral percentage for all other Eligible Employees multiplied by 1.25; or (2) the excess of the actual deferral percentage for the Highly Compensated Employees over the actual deferral percentage for all other Eligible Employees is not more than two percent (2%), and the actual deferral percentage for the Highly Compensated Employees is not more than the actual deferral percentage for all other Eligible Employees multiplied by 2.

For purposes of this Section 4.5(b), the “actual deferral percentage” for Highly Compensated Employees or for all other Eligible Employees for the applicable Plan Year shall mean the average of the ratios, calculated separately for each Employee in such group, of the amount of the Elective Contributions, if any, under the Plan on behalf of such Employee for such Plan Year to the Employee’s compensation, as defined under Section 414(s) of the Code, for such Plan Year. Unless otherwise elected by the Plan Administrator in accordance with Code Section 401(k)(3)(A) and any guidance from the Internal Revenue Service regarding such Code Section, the applicable Plan Year for the actual deferral percentage for Highly Compensated Employees shall be the current Plan Year, and the applicable Plan Year for the actual deferral percentage for non-Highly Compensated Employees shall be the preceding Plan Year.

The amount of Elective Contributions, if any, to be distributed pursuant to Section 4.5 shall be reduced by the amount of Elective Contributions in excess of the limitations prescribed by Section 402(g) of the Code (“Excess Deferrals”) which were returned prior to the reductions required in Section 4.5; provided that, in the event Elective Contributions are distributed to a Participant pursuant to Section 4.5 prior to the time Excess Deferrals with respect to a Plan Year are returned to the Participant, then the amount of such Excess Deferrals, if any, shall be reduced by the amount of Elective Contributions previously returned in accordance with the provisions of Section 4.5.

For purposes of this Section, the actual deferral percentage for any Participant who is a Highly Compensated Employee and who is eligible to have elective deferrals allocated to his or her accounts under two or more arrangements described in Code Section 401(k), that are maintained by the Employer (or of any trade or business, whether or not incorporated, which is considered to be under common control with the Employer under regulations prescribed by the Secretary of the Treasury pursuant to Code Section 414(c)), shall be determined as if such elective deferrals were made under a single plan. If a Highly Compensated Employee participates in two or more cash or deferred arrangements that have different plan years, all elective deferrals made during the Plan Year under all such plans and arrangements shall be aggregated. Notwithstanding the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Code Section 401(k).

In the event that the Plan satisfies the requirement of Sections 401(k), 401(a)(4) or 410(b) of the Code only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of such sections of the Code only if aggregated with this Plan, then this Section 4.5(b) shall be applied by determining the actual deferral percentages of eligible Participants as if all such plans were a single plan.

4.6 Catch-Up Contributions. Each Participant that is eligible to make Elective Contributions pursuant to Section 4.1 and who will have attained or exceeded age 50 before the close of a Plan Year shall be eligible to make Catch-Up Contributions with respect to that Plan Year in accordance with, and subject to the limitations of, Section 414(v) of the Code and any regulations promulgated thereunder. Catch-Up Contributions shall not be taken into account for purposes of implementing the required limitations of Sections 402(g) and 415 of the Code. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Sections 401(k)(3), 410(b) or 416 of the Code, as applicable, by reason of the making of such Catch-Up Contributions. Catch-Up Contributions shall be invested in the manner prescribed under Article VIII. The elections described in this Section 4.6 shall be made under procedures established by the Committee.

ARTICLE V

EMPLOYER CONTRIBUTIONS

5.1 Matching Contribution. With respect to each Plan Year, the Employer shall contribute to the Trust Fund on behalf of each Participant an amount equal to a percentage of

such Participant’s Elective Contributions in the amount and in such manner as determined in the sole discretion of the Plan Administrator. The Employer may designate, at the time of Contribution, that all or a portion of such Matching Contributions be treated as Qualified Nonelective Contributions.

5.2 Discretionary Contribution. With respect to each Plan Year, the Employer may contribute to the Trust Fund on behalf of each Participant an amount determined in the sole discretion of the Plan Administrator. Such Discretionary Contributions, if any, shall be allocated as of the last day of the Plan Year for which such contributions are made to each Participant who is an Eligible Employee of the Employer on the last day of the Plan Year, regardless of Participant’s active status in making Elective Contributions during any portion of the Plan Year.

For each Plan Year, the Discretionary Contribution, if any, shall be allocated to each Participant in the proportion that the Compensation paid to each Participant during the Plan Year bears to the Compensation paid to all such Participants eligible to receive the Discretionary Contributions; provided, that for this purpose, the amount of Compensation for all Participants shall be calculated without the exclusion set forth in Section 2.9(f).

5.3 Actual Contribution Testing Requirements.

(a) Reduction of Employer Contributions. If after the close of the Plan Year the Plan Administrator determines that the Plan may not satisfy the actual contribution percentage test of Section 401(m)(2) of the Code and any guidance issued by the Internal Revenue Service regarding Code Section 401(m)(2), as defined in Section 5.3(b) hereafter, then the Employer may make Qualified Nonelective Contributions sufficient to satisfy the Contribution Percentage Test. If the Plan Sponsor does not make Qualified Nonelective Contributions in order to satisfy the Contribution Percentage Test, the Plan Administrator shall reduce the Matching Contributions of Highly Compensated Employees, to the extent necessary to satisfy the contribution percentage test, in accordance with the terms of this paragraph. First the Highly Compensated Employee (or Highly Compensated Employees if more than one has the same amount of Matching Contributions) with the highest Matching Contributions shall have his or her Matching Contributions reduced until his or her Matching Contributions equals the Matching Contributions of the Highly Compensated Employee(s) with the next highest Matching Contributions; provided that a lesser reduction shall be appropriate if such lesser reduction would equal the total excess aggregate contributions computed under this Section. If the total excess aggregate contributions are not distributed by this initial reduction, then the Highly Compensated Employees with the highest Matching Contributions shall have their Matching Contributions reduced until their Matching Contributions equal the Matching Contributions of the Highly Compensated Employee(s) with the next highest Matching Contributions; provided that a lesser reduction shall be appropriate if such lesser reduction would equal the total excess aggregate contributions computed under this Section. Such reductions shall continue in the same manner until the total excess aggregate contributions have been distributed. To the extent possible, any distributions shall be made from Elective Contributions first. If any monies are distributed in accordance with this Section 5.3, any income allocable thereto for such Plan Year and for the period between the close of the Plan Year and the date of distribution shall be distributed to the appropriate Highly Compensated Employees. Notwithstanding any other provision of the Plan,

any excess contributions, and income allocable thereto, shall be distributed in accordance with this Section 5.3 no later than the last day of each Plan Year to Highly Compensated Employees to whose Plan Accounts such excess contributions were allocated for the preceding Plan Year.

The Plan may use any reasonable method for computing the income or loss allocable to excess aggregate contributions, provided that the method does not violate Code Section 401(a)(4), is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to Participants’ accounts. Alternatively, the Plan may elect to use a method of allocating Plan Year or gap period income specified under Treasury Regulation Section 1.401(m)-2(b)(2)(iv). Notwithstanding the foregoing, effective for Plan Years beginning on and after January 1, 2008, gap period income will not be included when making distributions of excess aggregate contributions.

In order to satisfy the Contribution Percentage Test, the Employer may, in its sole discretion, make Qualified Nonelective Contributions on behalf of any Participants who are not Highly Compensated Employees, as deemed appropriate by the Plan Administrator, in an amount sufficient to satisfy the nondiscrimination test of Section 5.3. The Employer may, in its sole discretion, make such Qualified Non Elective Contributions as either a percentage of Compensation or as additional Matching Contributions. Any Qualified Nonelective Contributions made by the Employer shall comply with the requirements set forth in Treasury Regulation 1.401(m)-2(a)(6), as in effect on January 1, 2006.

(b) Contribution Percentage Test. For purposes of Section 5.3 “contribution percentage test” shall mean a test which is satisfied if either one of the following two tests are satisfied: (a) the contribution percentage for the Highly Compensated Employees is not more than the contribution percentage for all other Eligible Employees multiplied by 1.25; or (b) the excess of the contribution percentage for the Highly Compensated Employees over the contribution percentage for all other Eligible Employees is not more than two percent (2%), and the contribution percentage for the Highly Compensated Employees is not more than the contribution percentage for all other Eligible Employees multiplied by 2. For purposes of this Section 5.3(b), the “contribution percentage” for Highly Compensated Employees or for all other Eligible Employees for a Plan Year shall mean the average of the ratios, calculated separately for each Employee in such group, of the amount of the Matching Contributions under the Plan paid on behalf of such Employee for such Plan Year to the Employee’s compensation, as defined under Section 414(s) of the Code, for such Plan Year.

For purposes of this Section 5.3, “contribution percentage test” for Highly Compensated Employees or for all other Eligible Employees for the applicable Plan Year shall mean the average of the ratios, calculated separately for each Eligible Employee in such group, of the amount of the Matching Contributions, Employee Contributions and Qualified Non-elective Contributions under the Plan paid on behalf of such Employee for such Plan Year to the Employee’s compensation, as defined under Code Section 414(s) for such Plan Year. Unless otherwise elected by the Committee in accordance with Code Section 401(m)(2)(A) and any guidance from the Internal Revenue Service regarding such Code Section, the applicable Plan Year for the contribution percentage for Highly Compensated Employees shall be the current

Plan Year, and the applicable Plan year for the contribution percentage for non-Highly Compensated Employees shall be the preceding Plan Year.

For purposes of this Section 5.3, the contribution percentage for any Participant who is a Highly Compensated Employee and who is eligible to participate in more than one plan described in Code Section 401(a), or arrangements described in Code Section 401(k), that are maintained by the Employer (or of any trade or business, whether or not incorporated, which is considered to be under common control with the Employer under regulations prescribed by the Secretary of the Treasury pursuant to Code Section 414(c)), shall be determined as if the total of such contribution percentage amounts were made under a single plan. If a Highly Compensated Employee participates in two or more cash or deferred arrangements that have different plan years, all contribution percentage amounts made during the Plan Year under all such plans and arrangements shall be aggregated. Notwithstanding the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Code Section 401(m).

In the event that the Plan satisfies the requirement of Sections 401(m), 401(a)(4) or 410(b) of the Code only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of such sections of the Code only if aggregated with this Plan, then this Section 5.3(b) shall be applied by determining the contribution percentages of eligible Participants as if all such plans were a single plan.

5.4 Investment of Employer Contributions. Matching Contributions, Discretionary Contributions and Qualified Nonelective Contributions, if any, shall be invested in the manner prescribed under Sections 8.5, 8.6 and 8.7.

ARTICLE VI

VESTING OF ACCOUNTS

6.1 Immediate Vesting of Certain Accounts. A Participant will at all times be 100 percent vested in his or her Elective Contribution Account, Catch-Up Contribution Account, Employee Contribution Account, Qualified Nonelective Contribution Account and Rollover Contribution Account.

6.2 Vesting of Employer Contributions. Each Participant will have a vested interest in a percentage of his or her Matching Contribution Account and Discretionary Contribution Account determined in accordance with the following schedule and based on his or her Years of Vesting Service:

Years of Vesting Service		Applicable Percentage

fewer than 1		0%
1 but fewer than 2		33 1/3%
2 but fewer than 3		66 2/3%
3 or more		100%

Notwithstanding the above, upon reaching Normal Retirement Date or if a Participant dies or becomes Disabled while an Employee, such Participant shall become 100% vested in all of his or her Accounts. If a Participant dies on or after January 1, 2007 while performing Qualified Military Service (as defined in Section 30.1), then such Participant’s interest in his or her Matching Contribution Account and Discretionary Contribution Account on the date of his or her death shall be 100%.

6.3 Forfeitures.

In the case of a Participant who incurs five consecutive One Year Breaks in Service, any portion of his Account in which he does not have a nonforfeitable interest shall be forfeited.

(a) If a Participant whose employment is terminated elects not to receive a distribution of the nonforfeitable portion of his Account pursuant to Article XIV, then the portion of his Account that is not vested shall be reallocated as a forfeiture at the end of the Plan Year in which his or her employment terminated. If such a Participant subsequently is rehired prior to incurring five (5) consecutive One-Year Breaks in Service, then the portion of his Account previously reallocated as a forfeiture shall be restored as if the Participant’s employment had not terminated.

(b) If a Participant whose employment is terminated receives a distribution of the value of the nonforfeitable portion of his Account, then any portion of his or her Account in which the Participant does not have a nonforfeitable interest shall be forfeited and shall be applied (i) to the restoration of any Accounts of Employees as required for such Plan Year and (ii) in the Employer’s discretion to reduce the Matching Contribution or Discretionary Contribution, if any, or to pay reasonable expenses of administering the Plan, at the earliest opportunity after such forfeitures become available.

If such Participant shall again become an Eligible Employee prior to incurring five (5) consecutive One-Year Breaks in Service, the Employer shall restore (as of the Participant’s reemployment) the dollar value of his account which was forfeited, unadjusted for any gains or losses which occurred during said break in service period (and the period provided hereinafter for repayment). The value of any such forfeited amounts shall be restored to a Participant’s Account and reinvested in the Participant’s Discretionary Contribution Account. Restoration of the amount forfeited hereunder will be provided only if the Participant repays the amount of any prior distribution within five years of the date of his rehire or, if earlier, before the close of the first period of five consecutive One-Year Breaks in Service beginning with the year in which the distribution occurred. Sums repaid by the Participant shall be reinvested in the Participant’s Discretionary Contribution Account. The provisions of this Section regarding the reinvestment of amounts repaid or restored to a Participant’s Account shall apply to each Participant or former Participant who has been reemployed by the Employer, whether before or after the Effective Date.

ARTICLE VII

ROLLOVER CONTRIBUTIONS

Any Employee may file a written petition with the Trustee requesting that the Trustee accept a Rollover Contribution from such Employee. The Trustee shall determine, based on the criteria contained in the written administrative procedures agreed to between the Trustee and the Committee, whether or not such Employee shall be permitted to contribute a Rollover Contribution to the Trust. Any written petition filed pursuant to this Article VII shall set forth the amount of the proposed Rollover Contribution, and contain a statement, as described in the written procedures, that the proposed Rollover Contribution constitutes a Rollover Contribution.

Subject to the foregoing provisions of this Article VII, effective April 1, 2010, the Plan will accept a Rollover Contribution that includes after-tax Employee Contributions from a qualified plan described in Code Section 401(a) or 403(a); provided, that the Plan will not accept Rollover Contributions of Roth elective deferral contributions.

ARTICLE VIII

ACCOUNTS AND CONTRIBUTIONS

8.1 Establishment of Accounts. The Trustee shall establish and maintain a separate Elective Contribution Account, Employee Contribution Account and Catch-Up Contribution Account, if applicable, in the name of each Participant to which shall be credited Elective Contributions, Employee Contributions and Catch-Up Contributions, respectively, made to the Trust Fund under Section 4.1. Upon receipt of a Rollover Contribution to the Trust, such Rollover Contribution shall become part of the Trust Fund and shall be held by the Trustee in an Employee’s Rollover Contribution Account. The Trustee also shall establish and maintain a separate Matching Contribution Account and Discretionary Contribution Account in the name of each Participant to which shall be credited the portion of each Matching Contribution and Discretionary Contribution, respectively, credited to such Participant under Sections 5.1 and 5.2, respectively. The Trustee shall also establish a Qualified Nonelective Contribution Account in the name of each Participant who actually is credited with Qualified Nonelective Contributions, to which account shall be credited the portion of Qualified Nonelective Contributions credited to such Participant, if any.

9.1 Limitations on Contributions. Notwithstanding any other provision of the Plan to the contrary, the annual addition to a Participant’s Plan Accounts under this Plan and any other defined contribution plans maintained by the Employer (or by any trade or business, whether or not incorporated, which is considered to be under common control with the Employer under regulations prescribed by the Secretary of the Treasury pursuant to Code Section 414(c)),with respect to a Plan Year, which shall be the “limitation year,” shall not exceed the lesser of (a) Forty Six Thousand Dollars ($46,000), as adjusted for cost of living increases under Code Section 415(d) and the regulations thereunder, or (b) one-hundred percent (100%) of the Participant’s total compensation, which for purposes of this Article IX shall mean “wages” as defined in Code Section 3401(a) and all other payments of compensation to an Employee by the Employer (in the course of the Employer’s trade or business) for which the Employer is required to furnish the Employee a written statement under Code Sections 6041(d), 6051(a)(3) and 6052 determined without regard to any rules under Code Section 3401(a) that limit the remuneration included in wages based on the nature or location of the employment or the services rendered.

The applicable rules of Code Section 415 and the final regulations promulgated thereunder hereby are incorporated by reference.

9.2 Excess Contributions. For limitation years beginning prior to January 1, 2008, if, as a result of a reasonable error in estimating a Participant’s Compensation, a reasonable error in determining the amount of Elective Contributions or other facts and circumstances to which Treasury Regulation 1.415-6(b)(6) applies, it is determined that the annual additions to a Participant’s Plan Accounts with respect to a Plan Year exceed the limitations contained in Section 9.1, such annual additions shall be held in an unallocated suspense account and allocated in subsequent years in accordance with the regulations under Code Section 415 or, alternatively, reduced to the extent necessary to bring them within such limitation by the return to the Employee of such excess amount consisting of Elective Contributions and earnings attributable thereto.

The term of a loan shall not exceed five (5) years, unless such loan is for the purpose of acquiring the Participant’s principal residence, in which case the loan may be for any reasonable period of time determined by the Committee. An Employee on an approved leave of absence without pay may request a suspension of repayment for a period of time not to exceed one year. Any such suspension, however, shall not extend the maximum five (5) year term of the loan, if applicable. Notwithstanding the foregoing, an Employee on qualified military leave may request a suspension of repayment for the term of the military leave service. Such extension can extend the maximum five (5) year term of the loan by the length of the military leave.

20.8 Default. A loan granted pursuant to this Article XX that is not repaid shall be deemed to be in default upon the earlier of (1) the date the Participant Terminates Employment, (2) the Participant’s failure to make payment on the loan as due, to the extent such failure causes the loan to fail to satisfy the requirements of Section 20.7, or (3) in the case of death while employed, within a reasonable time established by the Committee. At the time of such default, the Committee shall foreclose on the loan and deduct any outstanding balance plus accrued interest from the Participant’s Account balances immediately prior to distribution.

20.9 Exceptions to Default Rule. Notwithstanding any provisions in Section 20.8 to the contrary, a loan granted to a Participant under the terms of a tax-qualified plan allowing for repayment of a loan following termination of employment which loan was acquired by the Plan Sponsor pursuant to the acquisition of an Affiliated Employer shall not be deemed to be in default upon the date such Participant Terminates Employment. In addition, loans granted to Participants under the terms of another tax-qualified retirement plan that are transferred to the Plan shall not be deemed to be in default upon the date such Participant Terminates Employment to the extent the terms of such loans allow for repayment of the loans following Termination of Employment.

20.10 Additional Rules. All loans shall be subject to such further rules and regulations as the Committee shall from time to time prescribe and administer in a non-discriminatory manner.

20.11 General Dynamics Satellite Systems Group Loans. Effective June 1, 2010, employees of the General Dynamics Satellite Systems Group (the “General Dynamics Group”)

who become Employees as part of and at the time of the 2010 acquisition of the operating assets of the General Dynamics Group may transfer outstanding loans to the Plan that were granted to the Employees under the terms of the tax-qualified defined contribution plan that covered the employees of the General Dynamics Group immediately prior to the 2010 acquisition (the “General Dynamics Plan”) provided:

(a) any such Employee agrees to transfer all of the Employee’s assets held in his or her plan account under the General Dynamics Plan to this Plan; and

(b) any such transferred loan is not in default at the time of transfer to the Plan. For purposes of this Section 20.11(b), a loan will not be considered in default at the time of transfer if the Participant still is entitled to make up any missed payments during any grace period provided under the terms of the General Dynamics Plan.

ARTICLE XXI

In the event a Participant or Beneficiary who is receiving or is entitled to receive a benefit provided under the Plan attempts to assign, transfer or dispose of such right, or if an attempt is made to subject said right to such process, such assignment, transfer or disposition shall be null and void.

Any such expenses not paid from the Trust shall be paid by the Employer as determined by the Committee. To the extent permitted by the Code and ERISA, the Committee may direct the Trustee to reimburse the Employer from the Trust for a reasonable expense of administering the Plan which is paid by the Employer prior to a determination with respect to such expense.

22.6 Correcting Operational Defects. The Committee will have the full discretionary power and authority to correct any “operational defect” in any manner or by any method it deems appropriate in its sole discretion in order to cause the Plan (i) to operate in accordance with its terms or, (ii) to maintain its tax-qualified status under the Code. For purposes of this Section, an “operational defect” is any operational or administrative action (or inaction) in connection with the Plan which, in the judgment of the Committee, fails to conform with the terms of the Plan or causes or could cause the Plan to lose its tax-qualified status under the Code.

ARTICLE XXIII

TOP-HEAVY PROVISIONS

23.1 In General. If the Plan should for any Plan Year become top-heavy as defined in Section 23.2, then, notwithstanding any other provisions of the Plan, the rules in Section 23.3 shall apply to the Plan.

23.2 Top-Heavy Determination.

(a) Top-Heavy Defined. The Plan is top-heavy for a Plan Year if, as of the Determination Date, the aggregate of the Accounts under the Plan for Key Employees exceeds sixty percent (60%) of the aggregate of the Accounts for all Employees, as computed under Section 416(g) of the Code. The “Determination Date” for purposes of Article XXIII shall mean the last day of the Plan Year preceding the Plan Year in question. The value of the accumulated benefit for any Employee as of a Plan Year shall include the aggregate distributions, including withdrawals, made with respect to such Employee under the Plan, and any plan aggregated with the Plan under Section 416(g)(2) of the Code and Section 23.2(b), during the one-year period ending on the Determination Date. Notwithstanding the foregoing, in case of a distributions made for a reason other than severance from employment, death, or disability, “five-year period” shall be substituted for “one-year period.” The Accounts of any individual who has not performed services for the Employer during the one-year period ending on the Determination Date shall not be taken into account.

(b) Required Aggregation Groups. If the Plan is required to be aggregated with other plans under the provisions of the following sentences, then the aggregated plans taken together shall constitute the Plan for purposes of this Section 23.2. Notwithstanding the foregoing, if the Plan is required to be aggregated with a group of plans in a required aggregation group then if the required aggregation group is not top-heavy for a Plan Year, the Plan is not

top-heavy for that Plan Year, and if the required aggregation group is top- heavy for a Plan Year, then the Plan is top-heavy for that Plan Year. For purposes of the preceding sentence, a required aggregation group means each plan of the Employer (or of a trade or business, whether or not incorporated, which is considered to be under common control with the Employer under regulations prescribed by the Secretary of the Treasury pursuant to Section 414(c) of the Code) in which a Key Employee participates, and each other such plan which enables any plan in which a Key Employee participates to meet the coverage and anti-discrimination requirements of Sections 401(a)(4) and 410 of the Code, including any terminated plan which, had it not been terminated, would have been aggregated with the Plan under Section 416(g)(2)(A)(i) of the Code.

(c) Permissive Aggregation Groups. Notwithstanding the above provisions, the Plan will not be top-heavy in any Plan Year in which a permissive aggregation group to which the Plan belongs is not top-heavy. A permissive aggregation group consists of plans maintained by the Employer (or by any trade or business as described above) that are required to be aggregated plus one or more plans that are not part of a required aggregation group but that satisfy the requirements of Sections 401(a)(4) and 410 of the Code when considered together with the required aggregation group.

(d) Top-Heavy Determination for a Group. A required aggregation group or a permissive aggregation group is top-heavy for a Plan Year if, as of the Determination Date, the sum of the present value of the cumulative accrued benefits for Key Employees under all defined benefit plans included in such group and the aggregate of the accounts of Key Employees under all defined contribution plans included in such group exceeds sixty percent (60%) of a similar sum determined for all participants in such plans under Section 416(g) of the Code.

23.3 Top-Heavy Contingent Provisions. If the Plan is top-heavy for a Plan Year, as defined in Section 23.2, then the following Plan provisions shall apply for that Plan Year:

(a) The combined Employer Contribution and the contributions under any other defined contribution plan of the Employer (or of a trade or business as described in Section 23.2(b)) for the Plan Year for each Participant who is not a Key Employee, expressed as a percentage of compensation and after adding thereto all Elective Contributions made by each such Participant, shall be not less than the lesser of 3 percent or the largest percentage calculated in the same manner for any Key Employee. “Compensation” for purposes of this Article XXIII shall mean all compensation paid to a Participant as an Employee during the Plan Year for personal services rendered in the course of employment within the meaning of Section 415(c)(3) of the Code.

(b) In calculations made under the Plan, no more than two hundred and five thousand dollars ($205,000.00) of a Participant’s annual compensation may be taken into account. Such figure may be adjusted annually under determinations made by the Secretary of the Treasury.

(c) For purposes of this Section 23.3, Employer Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2)

of the Code. Employer Contributions that are used to satisfy the minimum contribution requirements shall be treated as Employer Contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code.

ARTICLE XXIV
FUNDING POLICY

The Committee shall establish a funding policy and method consistent with the objectives of the Plan and the requirements of Title I of ERISA. The Committee shall meet at least annually to review such funding policy and method. In establishing and reviewing such funding policy and method, the Committee shall endeavor to determine the Plan’s and Plan Participants’ short-teen and long-term objectives and financial needs. All actions of the Committee taken pursuant to this Article XXIV, and the reasons therefor, shall be communicated to the Trustee.

ARTICLE XXV

TERMINATION OF PLAN AND
DISCONTINUANCE OF CONTRIBUTIONS

25.1 Plan Termination. The Employer shall have the right, at any time, to terminate or partially terminate the Plan by formal action of the Board, or a committee thereof, in accordance with state law either at a regularly scheduled meeting of the Board, or a committee thereof, or by written consent. Upon full or partial termination of the Plan without the establishment of a successor plan, as described in Section 401(k)(10)(A)(i) of the Code, the Plan Sponsor shall direct the Trustee to distribute all assets remaining in the Trust, after payment of any expenses properly chargeable against the Trust, to the Participants in accordance with the Plan Accounts of each participant at the time of distribution, in cash, and in such manner as the Plan Sponsor shall determine. In the event of full or partial termination, each affected Participant shall be fully vested in such Participants’ Accounts.

25.2 Discontinuance of Contributions. Upon complete discontinuance of Elective Contributions, Employee Contributions, Matching Contributions and Discretionary Contributions to the Plan, the Plan Sponsor shall direct the Trustee to continue to maintain separate Plan Accounts for each Participant, to accumulate earnings and profits thereon, and to distribute benefits under Articles XII, XIII, XIV and XV of the Plan. In the event of complete discontinuance of Matching Contributions, Discretionary Contributions, Elective Contributions and Employee Contributions to the Plan, each Participant shall be fully vested in such Participant’s Accounts.

ARTICLE XXVI

AMENDMENT OF THE PLAN

26.1 Power to Amend Plan. The Employer shall have the right at any time, and from time to time, to amend, in whole or in part, any or all of the provisions of this Plan, including any obligation of the Employer under Article V, by formal action of the Board, or a committee thereof, in accordance with state law either at a regularly scheduled meeting of the Board, or a committee thereof, or by written consent. Any written amendment to the Plan under this Section

26.1 shall be executed by the Plan Sponsor on behalf of the Employer. However, no such amendment shall authorize or permit any part of the Trust Fund (other than such part as is required to pay taxes and administration expenses) to be used for, or diverted to, any purpose other than the exclusive benefit of the Participants or their Beneficiaries or cause any reduction in the amount previously credited to any Participant or permit any portion of the Trust Fund or the Accounts to revert to, or become the property of, the Employer. No amendment to this Plan which affects the rights, duties, or responsibilities of the Trustee may be made without the Trustee’s written consent.

26.2 Effective Date of Amendment. Any amendment to the Plan shall become effective upon the date specified as the effective date of the amendment.

To the extent required by the Uniformed Services Employment and Reemployment Rights Act of 1994 (“USERRA”) and Section 414(u) of the Code, effective December 12, 1994, and in accordance with this Article XXIX, a Reemployed Veteran shall be entitled to the restoration of certain benefits under the Plan that would have accrued, or that he or she would have received, under the Plan but for his or her absence from the employ of the Employer due to Qualified Military Service. “Reemployed Veteran” shall be defined as an Employee who left the employ of the Employer in order to perform service in the Armed Services of the United States, and subsequently was reemployed by the Employer pursuant to USERRA. “Qualified Military Service” shall be defined as service in the uniformed services (as defined in chapter 43 of title 38, United States Code) performed by the Reemployed Veteran whose entitlement to reemployment rights pursuant to USERRA arose with respect to such service.

30.2 Crediting of Period of Qualified Military Service. To the extent required by USERRA and Section 414(u) of the Code, the Reemployed Veteran, for all purposes under the Plan, shall be credited with Hours of Service, as applicable, for the period of his or her absence from employment with the Employer due to Qualified Military Service, in accordance with the regulations or other rules provided by the Internal Revenue Service. In no event shall such Reemployed Veteran’s absence due to Qualified Military Service constitute a break in service.

30.3 “Make-up” Contributions

(a) Employee “Make-up” Contributions. To the extent required by USERRA and Section 414(u) of the Code, the Reemployed Veteran shall be permitted, pursuant to Article IV, to make additional Employee Contributions during the period which (1) begins on the Reemployed Veteran’s date of reemployment with the Employer, and (2) has the same length as the lesser of: (1) the period of Qualified Military Service multiplied by 3, or (2) five (5) years.

The maximum amount of additional Elective Contributions that the Reemployed Veteran is permitted to make is the maximum amount of such contributions that the Reemployed Veteran would have been permitted to make pursuant to Article IV had he or she continued to be employed by the Employer during the period of Qualified Military Service and received compensation. In addition, a Reemployed Veteran who makes Elective Contributions for the period of his or her Qualified Military Service shall be entitled to receive Matching Contributions under Section 5.1 as if such Elective Contributions were made during such period of Qualified Military Service. Compensation for purposes of this Subsection (a) and (b), below, shall be based on the rate of pay that the Reemployed Veteran would have received during the

period of Qualified Military Service had he or she remained employed by the Employer. If such rate of pay was not reasonably certain, such compensation shall be based on the Reemployed Veteran’s average Compensation from the Employer during (1) the twelve (12) month period immediately before the Qualified Military Service, or (2) if shorter, the period of employment immediately before the Qualified Military Service.

(b) Application of Annual Limitations to “Make-up” Contributions. To the extent permitted by USERRA and Section 414(u) of the Code, any “make-up” contributions made pursuant to (a) above, shall not be treated as subject to the annual limitations on contributions set forth in Article IV for the Plan Year in which such contributions are made, but such “make-up” contributions shall be treated as subject to such annual limitations for the Plan Year to which such contributions relate, in accordance with the regulations or other rules provided by the Internal Revenue Service.

30.4 Forfeitures and Earnings. A Reemployed Veteran shall not share in the allocation of Forfeitures for any Plan Year in which the Reemployed Veteran was performing Qualified Military Service nor shall such Reemployed Veteran be entitled to any earnings in his or her make-up contributions until such contributions are made. Such earnings shall be made on a prospective basis from the date of the make-up contributions.

IN WITNESS WHEREOF, Orbital Sciences Corporation has caused this Plan to be executed and sealed by its duly authorized officers.
