ARTICLE II

PLAN FOR EXCLUSIVE BENEFIT OF EMPLOYEES

2.01 Type of Plan. This Plan is a profit sharing plan and contains a cash or deferral arrangement pursuant to which each Participant may elect to defer a portion of his Compensation to be contributed to the Plan. The Plan was originally established and continues for the exclusive benefit of the Employer’s Employees and their Beneficiaries. The provisions of this amended and restated Plan shall apply only to Employees who have Service on or after the Effective Date of this amended and restated Plan and Trust Agreement unless otherwise specified herein. The benefits of former Employees shall be determined under the Profit Sharing Plan, the Hancock 401(k) Plan, and/or the Whitney 401(k) Plan as in effect at the time such Employees terminated Service.

2.02 Return of Contributions. In the event a contribution made by the Employer is not deductible under Section 404 of the Code, the amount of the contribution disallowed (reduced by any losses) shall be returned to the Employer within one year after the deduction is disallowed. Any contribution (reduced by any losses) made by the Employer because of a mistake of fact shall be returned to the Employer within one year of the date of the contribution. The maximum amount that may be returned to the Employer under the preceding sentence is the excess of the amount contributed over the amount that would have been contributed had no mistake of fact occurred. Any earnings shall be allocated to the Participants.

2.03 Exclusive Benefit of Employees. Under no circumstances, except as provided in Section 2.02, shall any part of the principal or income of the Trust established hereunder be used for or revert to the Employer or be used for or diverted to purposes other than for the exclusive benefit of the participating Employees and their Beneficiaries.

However, the Plan shall not be construed as giving any Employee or other person any right, legal or equitable, against the Trustee, the Employer, or the principal or interest of the Trust except as specifically provided for herein. Furthermore, nothing herein contained shall be construed as giving any Participant the right to be retained in the service of the Employer nor, upon dismissal or upon the Participant’s voluntary termination, to have any right or interest in this Plan and Trust other than as provided herein.

2.04 Whitney 401(k) Plan. The Whitney 401(k) Plan was merged into this Plan effective January 1, 2013 and all accounts under the Whitney 401(k) Plan were transferred to this Plan. In accordance with the requirements under Section 414(l) of the Code, each Participant’s account balance after the merger equaled the sum of his or her account balances under the Whitney 401(k) Plan immediately prior to the merger.

The Appeals Committee shall provide the Claimant with notification of the Plan’s benefit determination on review. In the case of an Adverse Benefit Determination, the notification shall set forth the following information, in a manner calculated to be understood by the Claimant:

Upon the exhaustion of the administrative remedies provided herein, a Claimant shall be entitled to pursue such additional remedies as may be available under Section 502(a) of ERISA, provided that any such action is undertaken not more than two years from the day the final Adverse Benefit Determination on the Claim For Benefits was notified (or from the last day (including any extension) that the final Adverse Benefit Determination could have been timely notified) by the Appeals Committee.

ARTICLE V

ELIGIBILITY, DEFERRAL ELECTION AND DEFERRAL LIMITATION

5.01 Eligibility. Any Eligible Employee who has completed 60 days of continuous service and attained age 18 shall commence participation as soon as administratively feasible following the date on which the Employee meets such requirements, but no later than the second payroll period following such date.

5.02 Rehires. A former Participant (whether or not such Participant had a vested interest) shall become a Participant immediately upon reemployment as an Eligible Employee. An Employee who terminates employment after meeting the Plan’s eligibility requirements, but before becoming a Participant, shall, upon reemployment as an Eligible Employee, become a Participant on the later of the date he or she would have entered the Plan had he or she not terminated employment or the date of such reemployment.

5.03 Change of Employee Classification. In the event a Participant becomes ineligible to participate because he or she is no longer an Eligible Employee, but has not incurred a Break in Service, such Employee shall participate immediately upon again becoming an Eligible Employee. Such Employee’s accounts shall remain in the Plan and share in Net Earnings of the Trust Fund until distribution under the provisions of this Plan at the time the Employee retires, dies, becomes disabled or otherwise experiences a Severance from Employment.

In the event an Employee who is not an Eligible Employee becomes an Eligible Employee, such Employee shall participate immediately if such Employee has satisfied the age and Service requirements and would have otherwise previously become a Participant.

5.04 Deferrals. Each Participant may elect to defer a portion of his or her Compensation for each Plan Year, and his or her Compensation shall be reduced by the amount he or she elects to defer. Such deferral may be made as a whole percentage of Compensation or as a flat dollar amount. Effective January 1, 2016, flat dollar deferral elections shall no longer be allowed.

5.05 Automatic Deferrals. Each Participant who has failed to make an election to defer a portion of his or her Compensation shall be automatically enrolled in the Plan upon meeting the eligibility requirements. The amount of a Participant’s automatic deferrals shall be calculated as follows:

20

5.06 Revocation/Change. Any Participant who does not wish to defer or who desires to defer a different percentage may make an affirmative election to defer 0% or a different percent of Compensation prior to the commencement of automatic deferrals. Any Participant shall be permitted to make an election changing his or her automatic deferrals at any time, provided that amounts previously deferred shall not be returned to the Participant unless such Participant provides a written request to the Plan Administrator for the return of the automatic deferrals within 90 days of the making of the first deferral.

5.07 Deferral Limitations. Except as provided in the following paragraph, no Participant shall be permitted to have Elective Deferrals made under this Plan, or any other qualified plan maintained by the Employer during any taxable year, in excess of the dollar limitation contained in Section 402(g) of the Code in effect for such taxable year; and no Participant may defer an amount that will cause the Plan to violate the provisions of Section 7.04 of this Plan. The dollar limit is $18,000 for 2017. Amounts returned under the provisions of Section 7.05 of this Plan shall not be included for purposes of these limitations.

5.08 Catch-up Contributions. All Participants who are eligible to make Elective Deferrals under this Plan and who have attained age 50 before the close of their taxable year shall be eligible to make catch-up contributions in accordance with, and subject to the limitations of, Section 414(v) of the Code and Treasury Regulations thereunder. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Sections 401(a)(4), 401(k)(3), 410(b) or 416 of the Code, as applicable, by reason of the making of such catch-up contributions.

5.09 Crediting of Deferrals. The amount by which the Participant’s Compensation is reduced, including any catch-up contributions, shall be that Participant’s Elective Deferral and shall be contributed to the Plan by the Employer and allocated to the Participant’s Elective Deferral Account. The Plan Administrator may establish rules and procedures to facilitate the administration of Elective Deferrals, including but not limited to rules regarding minimum and/or maximum amounts of Elective Deferrals and a default investment fund for small amounts of Elective Deferrals.

5.10 Form of Elections. Elections under this Article shall be made by each Participant in writing or in a method provided by the Plan Administrator. All elections to defer or to change or revoke an election will be implemented as soon as administratively practicable.

21

5.11 Testing. Effective for Plan Years beginning on or after January 1, 2013, Elective Deferrals will not be subject to the discrimination tests that would have the effect of limiting contributions to Highly Compensated Employees, provided the Plan meets the requirements of a safe harbor plan pursuant to Section 401(k)(13) of the Code, Treasury Regulations under Sections 401(k) and 401(m) of the Code, IRS Notices 98-52 and 2000-3, and other IRS guidance.

For any Plan Year in which the Plan fails to satisfy the safe harbor plan requirements of Section 401(k)(13) of the Code, the Elective Deferral contributions made during such Plan Year must satisfy the nondiscrimination testing requirements under Section 401(k)(3) of the Code and Section 1.401(k)-2 of the Treasury Regulations, which are incorporated herein by reference.

For Plan Years beginning before January 1, 2013, nondiscrimination testing was performed using the current year method.

ARTICLE VI

PARTICIPATION

6.01 Terms of Plan. All Participants shall be bound by the terms of the Plan. Any person who does not wish to be a Participant must make a 0% deferral election and request a return of any automatic deferrals within 90 days of the first deferral.

6.02 Cessation of Participation. Participation in the Plan shall cease upon a Participant ceasing Service with the Employer and the full distribution of the Participant’s accounts. When an Employee fails to return to Service with the Employer by the date on which a layoff or authorized leave of absence expired, the Employee shall be considered as terminating Service on that date and the normal Break in Service rules shall apply.

ARTICLE VII

CONTRIBUTIONS

7.01 Elective Deferrals. For each Plan Year, the Employer shall contribute the Elective Deferrals of all Participants for the Plan Year to the Trust Fund on the earliest date the employer can reasonably segregate these amounts from its general assets, but in no event later than the fifteenth business day of the month following the month in which the employer withheld the contributions from the Employee’s paycheck.

7.02 HHC Safe Harbor Contributions. In addition to Elective Deferrals, the Employer shall make an HHC Safe Harbor Contribution each Plan Year on behalf of each Participant making Elective Deferrals under the Plan of 100% of the first 1% of Elective Deferrals and 50% of the next 5% of Elective Deferrals. HHC Safe Harbor Contributions shall be made no less frequently than quarterly.

7.03 Rollovers/Transfers. Rollover amounts and transferred amounts may be accepted under the following provisions:

22

All amounts rolled over to this Plan shall be in cash. The Trustee may require the Employee to establish that the amounts to be rolled over to the Trust meet all Code requirements. The Employee may be required to provide information regarding the amounts to be rolled over that will allow the Plan Administrator to reasonably conclude that the contribution is a valid rollover contribution. This information may include a determination letter with regard to the distributing plan. In the event the Plan Administrator reasonably concludes that the contribution is a valid rollover and later determines that the rollover is an invalid rollover, the amount of the invalid rollover, plus any earnings attributable thereto, shall be distributed to the Employee within a reasonable time after such determination. Amounts rolled over to this Plan on behalf of an Employee shall be placed in a Rollover Account for that Employee and shall be fully vested. Said account shall be invested jointly with the other assets and share in net earnings of the Fund when so invested, but shall not participate in Employer contributions. Such rollovers shall not be considered Annual Additions under Section 7.04 of this Plan. Upon an Employee’s entitlement to benefits under this Plan, the value of his or her Rollover Account or Accounts shall be distributed to him or her under the provisions of this Plan. A Rollover Account may be distributed for reasons of hardship under 11.05 of this Plan. Rollover Contributions under this Section shall be accepted for Employees who have completed at least one Hour of Service with the Employer.

23

Accounts transferred from the Whitney 401(k) Plan shall be held in separate accounts except the elective deferral accounts, which may be commingled with elective deferrals under this Plan.

The elective deferral accounts transferred to this Plan from the First State Bank and Trust Company Retirement Savings Plan and the First National Bank of Denham Springs Savings Plan and Trust shall be payable to the Participants upon termination of Service with the Employer. Deferrals allocated to these accounts and earnings credited to these accounts as of December 31, 1988, shall be eligible for Hardship distributions under the provisions of Section 11.05 of this Plan.

7.04 Annual Additions. Except to the extent permitted under Section 5.08 above, if applicable, the maximum Annual Additions (as defined in Section 415(c)(2) of the Code and Treasury Regulations thereunder) that may be made on behalf of any Participant for a Limitation Year shall not exceed the lesser of (a) $54,000, as adjusted or (b) 100% of the Participant’s Section 415 Compensation for the Limitation Year. For purposes of these limitations, all defined contribution plans of the Employer and Affiliated Employers shall be treated as one plan.

In determining the maximum Annual Additions to this Plan, Elective Deferrals (except catch-up contributions), Matching Contributions and Forfeitures shall be included. Amounts described in Sections 415(l)(2) and 419A(d)(2) of the Code shall also be included in determining the Annual Additions. The compensation limit referred to in (b) of the first paragraph of this Section 7.04 shall not apply to any contribution for medical benefits (within the meaning of Section 401(h) or Section 419A(f)(2) of the Code) after separation from employment which is otherwise treated as an Annual Addition.

In the event a short Limitation Year is created because of an amendment changing the Limitation Year to a different 12-consecutive month period, the maximum Annual Addition shall not exceed $54,000, as adjusted multiplied by a fraction, the numerator of which is the number of months in the short Limitation Year and the denominator of which is 12.

7.05 Suspension of Elective Deferrals. The Plan Administrator shall take any reasonable, uniform, and nondiscriminatory action to insure the Annual Additions for a Participant do not exceed the limitations of Section 7.04 for a Limitation Year. These include, but are not limited to the following: (a) Elective Deferrals may be suspended or limited; (b) the Employer’s future contribution may be reduced, and/or (c) the allocation of Employer contributions (exclusive of Elective Deferrals) and Forfeitures previously made to the Plan may be suspended or limited. Any amount suspended or limited under (c) in the preceding sentence will be allocated to the remaining Participants who are eligible for an allocation for the Plan Year. This allocation will be made in the accordance with the Plan provisions as if the Participant whose account would otherwise receive the allocation is not eligible for an allocation. The Annual Additions may be further reduced to the extent necessary, as determined by the Plan Administrator to prevent disqualification of the Plan under Section 415 of the Code.

24

Notwithstanding anything contained herein to the contrary, the limitations, adjustments and other requirements provided in Sections 7.04 and 7.05 shall, at all times, comply with the provisions of Section 415 of the Code and the Treasury Regulations thereunder, the terms of which are specifically incorporated herein by reference and the IRS’s Employee Plans Compliance Resolution System, Rev. Proc. 2016-51, as it may be amended or superseded.

7.06 Testing. Effective for Plan Years beginning on or after January 1, 2013, Employer matching contributions will not be subject to the discrimination tests that would have the effect of limiting such contributions to Highly Compensated Employees, provided the Plan meets the requirements of a safe harbor plan pursuant to Section 401(k)(13) of the Code, Treasury Regulations under Sections 401(k) and 401(m) of the Code, IRS Notices 98-52 and 2000-3, and other IRS guidance.

For any Plan Year in which the Plan fails to satisfy the safe harbor plan requirements of Section 401(k)(13) of the Code, the Employer matching contributions made during such Plan Year must satisfy the nondiscrimination testing requirements under Section 401(m)(2) of the Code and Section 1.401(m)-2 of the Treasury Regulations, which are incorporated herein by reference.

For Plan Years beginning before January 1, 2013, nondiscrimination testing was performed using the current year method.

ARTICLE VIII

ALLOCATION OF NET EARNINGS

8.01 Allocation Method. Net Earnings generated by the Participant’s directed investments under Section 21.09 (or default investments if no directions are received from the Participant) shall be allocated to the Participant’s accounts in accordance with the attributes of the separate investment funds and the Employer Stock fund, in a manner generally consistent with industry standards for daily recordkeeping.

8.02 Equitable/Nondiscriminatory Allocation. The Plan Administrator shall have sole authority to make determinations and resolve issues for purposes of this Article VIII. Should the Plan Administrator determine that the strict application of the foregoing allocation procedures will not result in an equitable and nondiscriminatory allocation among the accounts of Participants, or that another method is appropriate for the purpose, it may modify its procedures for the purpose of achieving an equitable and nondiscriminatory allocation in accordance with the general concepts of the Plan and the provisions of this Article.

8.03 Fees and Expenses. Notwithstanding any provision of this Plan to the contrary, the fees, expenses, commissions, loads, charges and similar deductions associated with investment in any fund offered hereunder shall be deducted from the Net Earnings attributable to each such fund before the allocation of such earnings hereunder; such fees, expenses, commissions, loads, charges and similar deductions need not be uniform with respect to each investment fund. The Employer, in its discretion, may pay or deduct from the assets comprising

25

the Trust, from time to time, the direct expenses of the Plan, including, without limitation, legal and accounting fees, Trustee’s fees and administrative and recordkeeping charges and expenses. If directed by the Employer, the Plan Administrator shall deduct such direct expenses from each Participant’s accounts on a pro rata basis. The Plan Administrator shall determine whether individual account expenses, including, without limitation, expenses incurred in connection with a distribution hereunder or the administration of a domestic relations order, shall be treated as and aggregated with other direct expenses of the Plan or borne by each affected individual account.

ARTICLE IX

ALLOCATION OF EMPLOYER CONTRIBUTIONS

9.01 Allocation of Elective Deferrals. Elective Deferrals shall be allocated to the Elective Deferral Account of each Participant as of the Valuation Date coinciding with or next following the date the Elective Deferral is contributed to the Plan. The amount of the allocation shall be equal to the Elective Deferrals of that Participant.

9.02 Allocation of Matching Contributions. The Matching Contributions made prior to January 1, 2013, were allocated to the Matching Contribution Account of each eligible Participant as of the Valuation Date coinciding with or next following the date the Matching Contribution was made to the Plan.

The HHC Safe Harbor Contribution shall be allocated to the HHC Safe Harbor Contribution Account of each eligible Participant as of the Valuation Date coinciding with or next following the date the HHC Safe Harbor Contribution is made to the Plan in the amount specified under Section 7.02 for each such Participant.

ARTICLE X

VESTING

10.01 Fully Vested Accounts. Each Participant’s Elective Deferral Account, Hancock Profit Sharing Account, Whitney Rollover Account, Whitney Safe Harbor Account, Transfer Account, Whitney Thrift Incentive Account, and Rollover Account shall be fully vested at all times.

10.02 Vesting due to Retirement, Death or Disability. Each Participant’s Matching Contribution Account, Whitney Profit Sharing Account, and HHC Safe Harbor Contribution Account shall be fully vested upon the Participant’s attainment of his or her Early or Normal Retirement Date, death or Disability while employed by the Employer.

10.03 Vesting Schedules. If a Participant shall terminate Service with the Employer for any reason other than death, Disability or retirement on or after the Plan’s Early or Normal Retirement Date, the Participant shall be entitled to his or her vested interest in the Plan determined based on his or her Years of Service. Such Participant shall be 100% vested in his or her Matching Contribution Account and/or Whitney Profit Sharing Account upon the completion of three Years of Service and shall be 100% vested in his or her HHC Safe Harbor Contribution Account upon the completion of two Years of Service.

26

10.04 Years of Service. For vesting purposes, a Participant shall receive credit for all Years of Service as determined under the definition of Year of Service in Article III of this Plan, provided that there shall be no requirement to earn 1,000 Hours of Service for purposes of the HHC Safe Harbor Contribution Account.

10.05 Break In Service Rules. In the event a former Participant incurs five consecutive one-year Breaks in Service and is rehired, his post-Break Years of Service shall not be utilized in determining his vested interest in his Matching Contribution Account, Whitney Profit Sharing Account and/or HHC Safe Harbor Contribution Account established prior to his Breaks in Service. Such Participant’s pre-Break in Service Years of Service shall be utilized for purposes of vesting the Participant’s post-Break Matching Contribution Account and/or HHC Safe Harbor Contribution Account, as applicable.

In the event a Participant does not have five consecutive one-year Breaks in Service, both the pre-break and post-break Service shall count in vesting the pre-break and post-break Matching Contribution Account and/or HHC Safe Harbor Contribution Account, as applicable.

10.06 Forfeitures. Upon termination of Service, the non-vested portion of a Participant’s Matching Contribution Account, Whitney Profit Sharing Account and/or HHC Safe Harbor Contribution Accounts, if any, shall be maintained in the Matching Contribution Account, Whitney Profit Sharing Account or HHC Safe Harbor Contribution Account, as applicable, until the Participant has a Forfeiture. On the last day of each Plan Year, prior to making any allocations, the amount of Forfeitures of Matching Contribution Accounts and/or HHC Safe Harbor Contribution Accounts as of that date shall be determined and shall be segregated. Forfeitures from the Matching Contribution Accounts, Whitney Profit Sharing Account and/or, effective January 1, 2015, the HHC Safe Harbor Contribution Accounts shall be utilized to pay Plan expenses or to reduce the amount of subsequent HHC Safe Harbor Contributions. For Plan Years starting on or after January 1, 2013, but before January 1, 2015, Forfeitures of HHC Safe Harbor Contributions could only be used to pay for Plan expenses.

ARTICLE XI

ELIGIBILITY FOR BENEFITS

11.01 Distribution Event. The vested account or accounts of a Participant whose Service with the Employer has been terminated due to retirement on or after his or her Early Retirement Date, Normal Retirement Date, death, Disability or other Severance of Employment, shall become payable on the first day of the month coinciding with or next following the Participant’s actual termination of Service. In the event a Participant attains his or her Early Retirement Date or Normal Retirement Date and retires, his or her benefits as of the date he or she retires shall be payable to the Participant under the provisions of this Section even if the Participant is rehired prior to receipt of all of such benefits. Any benefits accruing after such Participant is rehired shall be payable upon the Participant’s subsequent termination of Service.

Subject to the provisions of Sections 11.02 and 11.03, distributions shall commence as soon as administratively feasible after the date on which the benefit becomes payable, or, in the case of a benefit requiring a Participant’s consent, after the date of receipt of such consent. The amount of the distributions shall be based on the value of the Participant’s accounts as of the

27

Valuation Date preceding the date distributions commence. The Trustee shall have a reasonable time after receiving instructions from the Plan Administrator to make payments in conformity with such instructions and when the payments have been made the Trustee shall advise the Plan Administrator. During the period between the termination of a Participant’s Service and the Valuation Date immediately preceding the distribution, the Participant’s account or accounts shall continue to share in Net Earnings of the Fund but shall not share in Employer contributions. A Participant shall not receive Net Earnings during the period between such Valuation Date and the date of distribution.

Except as provided in Sections 11.04, 11.05, 11.06, 11.07 and Article XV, no distributions shall be made until a Participant terminates Service with the Employer.

11.02 Small Benefits. In the event the total vested interest of a Participant is not greater than $1,000 (including rollovers and transfers) at the date of distribution of benefits, the entire vested interest of the Participant shall be distributed in a lump sum to the Participant (or to the Participant’s Spouse or other Beneficiary if the Participant has died), without regard to the remaining provisions of this Article XI and without regard to the provisions of Article XII, except the direct rollover provisions of Section 12.03 (a “mandatory distribution”). Such a mandatory distribution shall be made without the written consent of the Participant, or without the consent of the surviving Spouse or other Beneficiary if the Participant has died. Such distribution shall be made as soon as administratively feasible after receipt of the Participant’s election as to a direct rollover as provided in Section 12.03. In the event no election as to a direct rollover is received from the Participant by the end of the 30-day period following notice to the Participant of his right to elect a direct rollover, distribution shall be made as soon as administratively feasible thereafter in accordance with the default procedure under Section 12.03.

11.03 Deferral of Benefit Payments. In the event the value of a Participant’s vested accounts exceeds $1,000 (including rollovers and transfers) and the Participant’s benefits are payable prior to the time the Participant attains the later of his or her Normal Retirement Date or age 62, the Participant must consent in writing to the distribution. Such consent must be obtained in writing within the 180-day period ending on the distribution date.

The Plan Administrator shall notify the Participant of the right to defer any distribution. The notification shall include a description of a Participant’s right, if any, to defer receipt of a distribution and the consequences of failing to defer receipt of the distribution. Such notification shall include a general description indicating the investment options available under the Plan (including fees) that will be available if distributions are deferred and an explanation of any special rules that might materially affect a Participant’s decision to defer and shall be provided no less than 30 days and no more than 180 days prior to the distribution date. The consent of the Participant is not required if a distribution is required under Section 401(a)(9) or Section 415 of the Code. Such distribution may commence less than 30 days after the notice is given, provided that:

28

11.04 Payment of Benefits. Unless a Participant elects otherwise, payment must begin not later than the 60^th day after the close of the Plan Year in which the latest of the following events shall occur: (a) the Participant reaches the earlier of age 65 or Normal Retirement Date, (b) the termination of the Participant’s Service with the Employer, or (c) the tenth anniversary of the year in which the Participant commenced participation in the Plan. However, the failure of a Participant to consent to a distribution as required under Section 11.02 shall be deemed to be an election to defer payment of any benefit sufficient to satisfy this paragraph.

In all events, distributions must commence no later than the Participant’s Required Beginning Date as defined in Article XIII.

11.05 Primary In-service Distributions. Distributions may be made prior to termination of a Participant’s Service only if the distribution is required under Section 11.04 or allowed under this Section 11.05 or Section 11.06, 11.07 or Article XV. Effective January 1, 2016, withdrawals made under this Section 11.04 must be made in amounts of at least $100.

29

11.06 Hardship. A Participant may request a distribution from the Plan for reasons of hardship. As used throughout this Plan, hardship shall mean immediate and heavy financial needs of the Participant, where such Participant lacks other available resources. Such needs shall include only the following:

Any hardship distribution to a Participant under this provision shall be in cash in a single sum. The amount of the hardship distribution shall not exceed the amount required to meet the immediate financial need of the Participant and may include any amounts necessary to pay any federal, state or local income taxes or penalties reasonably anticipated to result from the distribution.

Before a Participant can receive a hardship distribution under this Section, such Participant must have obtained all distributions (other than hardship distributions) and all nontaxable loans (other than hardship loans) currently available under all plans maintained by the Employer, including a request for dividend distribution. In the event a Participant receives a hardship distribution from this Plan, such Participant shall not be eligible to defer income under this Plan or to make any employee contribution to any other plan of the Employer, except

30

contributions to any health or welfare benefit plan, including one that is part of a cafeteria plan within the meaning of Section 125 of the Code, for six months after receipt of the hardship distribution. Upon conclusion of the six-month suspension period, a Participant’s Elective Deferrals shall automatically resume at the Participant’s elected deferral rate in effect at the time of suspension or, if the Participant’s Elective Deferrals were being made in accordance with the automatic deferral provisions under Section 5.05, at the applicable automatic deferral rate in effect as of the payroll period in which Elective Deferrals are to resume. Notwithstanding the preceding, the Participant may elect a different rate at which Elective Deferrals will resume at the end of the suspension period in accordance with the deferral election procedure in effect under the Plan.

Hardship distributions shall be made from the Participant’s Elective Deferral Account excluding Net Earnings allocated to such account and from any Profit Sharing Account, Whitney Profit Sharing Account, or Transfer Account pursuant to the provisions of Section 7.03(b), provided that any Participant who has not elected to receive his or her dividends in cash shall not be entitled to a hardship distribution from the Elective Deferral Account during such Plan Year.

11.07 Additional In-service Distributions. A Participant shall be entitled to an in-service distribution as follows:

ARTICLE XII

DISTRIBUTION OF BENEFITS

12.01 Election for Distribution. A Participant entitled to benefits under this Plan may elect any of the options for distribution of such benefits outlined in Section 12.02. Elections by the Participant shall be in writing and filed with the Plan Administrator. If a Participant becomes entitled to a distribution of benefits and does not make a written election, the Participant’s benefits shall be paid in a lump sum. Following the death of a Participant, the Participant’s Beneficiary may elect the distribution of any benefit to which such Beneficiary becomes entitled as a result of the Participant’s death to be made in any of the forms outlined in Section 12.02. In the event no election is made by the Beneficiary, distribution will be made in a lump sum. Upon receipt of a Participant’s or Beneficiary’s written election, the Plan Administrator shall direct the Trustee as to the time and method of payment of benefits, subject to the provisions of this Plan. Any election concerning the payment of any benefits under the Plan may be revoked in writing and another election made in writing at any time prior to the commencement of benefit payments.

31

12.02 Forms of Distribution. Subject to the provisions of Article XI and Article XIII, a Participant (or Beneficiary if applicable) whose total vested accounts exceed $1,000, may elect to receive benefits in cash or in kind, in the case of Employer Stock, in any one or more of the following methods:

If the account is being paid in installments or held in Trust in accordance with the provisions of this Section, the total account shall continue to share proportionately in the Net Earnings of the Trust but shall not share in Employer contributions.

12.03 Direct Rollover. In the event a distributee is entitled to receive a distribution under this Plan, such distributee may elect (subject to the restrictions listed below) to have the Trustee pay all or any portion of such distribution, which would otherwise be includable in gross income, directly to one or more eligible retirement plans specified by the distributee in a direct rollover. This provision shall not apply to (a) any distribution during a year in which such distributions to the distributee from this Plan are reasonably expected to total less than $200, (b) any distribution which is one of a series of substantially equal periodic payments (not less frequently than annually) made over a specified period of ten years or more, (c) any distribution to the extent such distribution is required under Section 401(a)(9) of the Code and Article XIII of this Plan, (d) the portion of any distribution that is not includable in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to Employer stock) and (e) any hardship distribution made under the provisions of Section 11.06 of this Plan. In the event the distributee elects to have only a portion of the distribution paid directly to an eligible retirement plan, such portion must be equal to at least $500. An election for a direct rollover with respect to one payment in a series of periodic payments will apply to all subsequent payments in the series, unless the distributee changes the election with respect to subsequent payments.

The term “eligible retirement plan” for distributions to Participants, surviving Spouses and Alternate Payees (who are the Spouse or former Spouse of a Participant) means (a) an individual retirement account described in Section 408(a) of the Code, (b) an individual retirement annuity described in Section 408(b) of the Code (other than an endowment contract), (c) a qualified plan described in Section 401(a) of the Code, the terms of which permit the acceptance of rollover distributions, (d) an annuity plan described in Section 403(a) of the Code, (e) an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state and which agrees to separately account for amounts transferred into such plan from this Plan, (f) an annuity contract described in Section 403(b) of the Code, and (g) a Roth individual retirement account described in Section 408A(b) of the Code, subject to the restrictions that apply to rollovers from a traditional individual retirement account into a Roth individual retirement account. However, if the distributee is a designated Beneficiary (as defined by Section 401(a)(9)(E) of the Code and amended by Section 402(c)(11)(B) of the Code) of a deceased Employee, other than the Employee’s surviving Spouse or an Alternate Payee, eligible

32

retirement plan shall mean only an individual retirement account described in Section 408(a) of the Code or an individual retirement annuity described in Section 408(b) of the Code (other than an endowment contract) established for the purpose of receiving a distribution on behalf of such designated Beneficiary.

A distributee electing a direct rollover must provide the Plan Administrator with the name of the eligible retirement plan and any other information required by the Plan Administrator or the Trustee to make the direct rollover.

In the event of a mandatory distribution under the provisions of Section 11.02 hereof, a distribution to a Beneficiary or a distribution to an Alternate Payee under a Qualified Domestic Relations Order, if the distributee does not notify the Plan Administrator of his election to have such distribution either (a) paid directly to an eligible retirement plan specified by the distributee in a direct rollover or (b) paid directly to the distributee within 30 days of being provided with notice of such right, such distribution shall be paid directly to the distributee subject to applicable tax withholding requirements.

12.04 Disability. Whenever and as often as any person entitled to payment hereunder shall be under a legal disability or otherwise unable to apply such payments to the person’s own best interest and advantage, the person’s Spouse, if married, or legal guardian or conservator shall determine the method of distribution of benefits and shall determine when the payment of benefit shall be made, subject to the provisions of this Plan. Such payments may be made in any one or more of the following ways: (a) directly to such person; (b) to the legal guardian or conservator; (c) to the person’s Spouse or to any other person, to be expended for benefit of the Participant; or (d) in the event such person is a minor, to a custodian for such person under the Uniform Transfer to Minors Act or Uniform Gift to Minors Act, if such is permitted by the laws of the state in which such person resides. The decision of the Spouse or, if no Spouse, legal guardian or conservator, shall in each case be final and binding upon all persons in interest.

ARTICLE XIII

REQUIRED MINIMUM DISTRIBUTIONS

13.01 General Rules. The requirements of this Article XIII shall apply to any distribution of a Participant’s interest and shall take precedence over any inconsistent provisions of the Plan. All distributions required under this Article shall be determined and made in accordance with the Treasury Regulations under Section 401(a)(9) of the Code and the minimum distribution incidental benefit requirement of Section 401(a)(9)(G) of the Code. Notwithstanding the other provisions of this Article, distributions may be made under a designation made before January 1, 1984, in accordance with Section 13.07 of this Plan.

As of the first Distribution Calendar Year (as defined below), distributions if not made in a lump sum, may only be made over a period certain not extending beyond the life expectancy of the Participant, or a period certain not extending beyond the joint and last survivor expectancy of the Participant and a Designated Beneficiary (as defined below).

34

13.02 Time and Manner of Distributions. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s Required Beginning Date (as defined below). If the Participant dies before required distributions begin, the Participant’s entire interest in the Plan will be distributed, or begin to be distributed, no later than as follows:

For purposes of this Section 13.02 (unless the Participant’s surviving Spouse is being treated as the Participant pursuant to the provisions of Section 13.02(a)), distributions are considered to begin on the Participant’s Required Beginning Date. If the Participant’s surviving Spouse is being treated as the Participant pursuant to the provisions of Section 13.02(a), distributions are considered to begin on the date distributions are required to begin to the surviving Spouse under Section 13.02(a).

Unless the Participant’s interest is distributed in a lump sum on or before the Required Beginning Date, as of the first Distribution Calendar Year distributions will be made in accordance with Sections 13.03, 13.04 and 13.05.

13.03 Distributions During Participant’s Lifetime. During the Participant’s lifetime, the minimum amount that must be distributed for each Distribution Calendar Year is the lesser of:

35

Required minimum distributions during the Participant’s lifetime will be determined under this Section 13.03 beginning with the first Distribution Calendar Year and continuing up to and including the Distribution Calendar Year that includes the Participant’s date of death.

13.04 Distributions After Participant’s Death – Death on or After Date Distributions Begin. If the Participant dies on or after the date required distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the longer of the remaining Life Expectancy of the Participant or the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as follows:

If there is no Designated Beneficiary as of the date of the death of the Participant who remains a Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the Participant’s remaining Life Expectancy under the Single Life Table described in (a) above calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

36

13.05 Distribution After Participant’s Death – Death Before Date Distributions Begin. If the Participant dies before the date required distributions begin, distributions will be made as follows:

13.06 Definitions. The following definitions shall apply to this Article XIII:

37

13.07 TEFRA Election. Notwithstanding the other requirements of this Article XIII, distributions on behalf of any Participant, including a 5% owner, may be made in accordance with a designation made in accordance with Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act (“Section 242(b)(2) election”) meeting all of the following requirements (regardless of when such distribution commences):

38

A distribution upon death will not be covered by this Section unless the information in the Beneficiary designation contains the required information described above with respect to the distributions to be made upon the death of the Participant.

For any distribution which commences before January 1, 1984, but continues after December 31, 1983, the Participant or the Beneficiary, to whom such distribution is being made, will be presumed to have designated the method of distribution under which the distribution is being made if the method of distribution was specified in writing and the distribution satisfies the requirements in (a) and (e) above.

If a designation is revoked, any subsequent distribution must satisfy the requirements of Section 401(a)(9) of the Code and Treasury Regulations thereunder. If a designation is revoked subsequent to the date distributions are required to begin, the Plan must distribute by the end of the calendar year following the calendar year in which the revocation occurs the total amount not yet distributed which would have been required to have been distributed to satisfy Section 401(a)(9) of the Code and Treasury Regulations thereunder, but for the Section 242(b)(2) election. For calendar years beginning after December 31, 1988, such distributions must meet the minimum distribution incidental benefit requirements. Any changes in the designation will be considered to be a revocation of the designation. However, the mere substitution or addition of another Beneficiary (one not named in the designation) under the designation will not be considered to be a revocation of the designation, so long as such substitution or addition does not alter the period over which distributions are to be made under the designation, directly or indirectly (for example, by altering the relevant measuring life).

In the case in which an amount is transferred or rolled over from one plan to another plan, the rules in Section 1.401(a)(9)-8 of the Treasury Regulations, Q&A-14 and Q&A-15, shall apply.

39

ARTICLE XIV

BENEFICIARIES

14.01 Designation of Beneficiary. Each Participant shall designate as a Beneficiary the person or persons to whom the Participant’s share of the Fund shall be paid in the event of death. The designation shall be in writing or electronically and may include contingent or successive Beneficiaries and shall be filed with the Plan Administrator in such form as the Plan Administrator requires. The Beneficiaries may be changed at any time or times by the Participant revoking all prior written designations and filing a new designation with the Plan Administrator. The Spouse of a married Participant must consent to each designation of a specific Beneficiary (including any class of Beneficiaries or any contingent Beneficiaries) other than the Spouse, and such designation may be changed without spousal consent provided a prior consent of the Spouse expressly permits designation by the Participant without any requirements of further consent by the Spouse. All spousal consents must (a) be in writing, (b) acknowledge the effect of such designation, and (c) be witnessed by a Plan representative or a notary public.

14.02 Deemed Beneficiary. If a Participant dies without having a Beneficiary designation then in force or if all the Beneficiaries designated by a Participant predecease the Participant, the Participant’s benefits shall be paid to the Participant’s Spouse as of the date of the Participant’s death and if no surviving Spouse, to the Participant’s estate.

14.03 Death of Beneficiary. If all Beneficiaries who were designated by a deceased Participant and who survived him or her shall die prior to the final and complete distribution of the Participant’s benefits, then, upon the death of the last to survive of said designated Beneficiaries, the estate of the last of said designated Beneficiaries to survive shall be deemed to be the Beneficiary of the unpaid portion of such deceased Participant’s benefits.

ARTICLE XV

LOANS

15.01 Eligibility for Loans. A Participant who is an Employee may make application to the Administrator to borrow from the vested portion of his or her accounts. The Administrator, in its sole discretion, may permit any such loan, subject to the following terms and conditions:

40

15.02 Number of Loans Outstanding. A Participant may only have one loan outstanding at a time. A Participant may not refinance an outstanding loan in order to meet this requirement.

ARTICLE XVI

TERMINATION AND MERGERS

16.01 Termination. By establishing a Plan hereunder the Employer represents such Plan is intended to be a permanent and continuing program for providing retirement benefits to the Participants therein, but the Sponsor nevertheless reserves the right to terminate its Plan at any time. In accordance with the procedures set forth in this Section and by written instrument, the Board of Directors may terminate the Plan at any time. By written board resolution, the Board of Directors may delegate the authority to execute the written instrument necessary to terminate the Plan to an officer or officers. The complete discontinuance of contributions or the complete cessation of active operation of the business or profession of the Employer with respect to which the Plan was established shall effect an automatic termination of the Plan, unless the Plan is continued by another employer.

16.02 Vesting and Distribution. Each affected Participant’s interest shall be nonforfeitable to the extent funded upon actual termination, partial termination, or complete discontinuance of contributions, without regard to any formal written notice. The Trust Fund shall remain in existence and benefits shall be distributed in the manner provided herein on the Participant’s termination of Service, death or Disability (or earlier, if allowed under the Plan).

41

However, lump-sum distributions shall be made to all Participants upon termination of this Plan if neither the Employer nor an Affiliated Employer maintains any other defined contribution plan (other than an employee stock ownership plan as defined in Section 4975(e)(7) of the Code) at the time of termination of this Plan or within 12 months following the distribution of all assets from this Plan. Such distributions may be made without the consent of the Participant required by Section 11.02 of this Plan. If the Employer or Affiliated Employer maintains another defined contribution plan (other than an employee stock ownership plan as defined in Section 4975(e)(7) of the Code) each Participant’s accounts shall be transferred to such plan upon termination of this Plan.

16.03 Merger. This Plan and Trust may be merged or consolidated with another plan which allows for mergers or consolidations; or the assets and liabilities of the Trust Fund may be transferred to another trust fund held under any other plan of deferred compensation maintained or established for the benefit of all or some of the Participants of this Plan. In the event of such merger, consolidation or transfer, the assets of the Trust Fund applicable to such Participants shall be transferred to the other trust fund only if:

ARTICLE XVII

AMENDMENT

17.01 Amendment By Sponsor. By written instrument executed by a duly authorized officer or officers, the Sponsor or its designee shall have the right at any time and from time to time to amend or modify this Plan, retroactively if required, in whole or in part as it may deem necessary or advisable without the consent of any Participant, former Participant or Beneficiary; except that:

42

17.02 Vested Interests. If any amendment directly or indirectly affects the computation of the nonforfeitable percentage of an Employee’s rights to Employer-derived benefits, or if the Plan is deemed amended by an automatic change to or from a Top Heavy vesting schedule, any Participant who has completed three or more Years of Service with the Employer may, upon written request to the Plan Administrator within 60 days after receipt of notice of such amendment, elect to have his or her nonforfeitable percentage computed without regard to such amendment. No amendment shall have the effect of decreasing a Participant’s vested interest determined without regard to such amendment as of the later of the date such amendment is adopted or the date it becomes effective.

ARTICLE XVIII

ALLOCATION OF FIDUCIARY RESPONSIBILITIES

18.01 Allocation of Duties. In general, each Employer shall have the sole responsibility for making contributions. The Board of Directors shall have the sole authority to terminate this Plan. The Board of Directors or their designee shall possess the authority to appoint and remove the Trustee and to amend the Plan. The Plan Administrator and the Investment Committee shall possess those administrative duties more fully set forth in Section 4.01 hereto. The Trustee shall act as a directed trustee and shall invest and reinvest the assets comprising the Trust in accordance with the terms of the Plan.

18.02 Fiduciary Responsibility. It is the intent of the Plan that each such Fiduciary shall be solely responsible for the proper exercise and discharge of the power and authority granted to it hereunder and that each such Fiduciary shall not be responsible for any action or failure to act by any other Fiduciary hereunder.

ARTICLE XIX

SPENDTHRIFT CLAUSE

19.01 Benefits Nonassignable. Except as provided in Section 19.02, benefits payable under this Plan shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind either voluntary or involuntary, including any such liability which is for alimony or other payments for the support of a Spouse or former Spouse, or for any other relative of the Employee, prior to actually being received by the person entitled to the benefit under the terms of the Plan, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, charge or otherwise dispose of any right to benefits payable hereunder shall be void. The Trust Fund shall not in any manner be liable for, or subject to, the debts, contracts, liabilities, engagements or torts of any person entitled to benefits hereunder.

43

Effective for Participants in the Plan as of December 31, 2012, a Participant or Beneficiary who has begun receiving benefits may assign or alienate the right to future benefit payments provided that the provision is limited to assignments or alienations which meet all of the following requirements: (a) they are voluntary and revocable at any time; (b) they do not in the aggregate exceed 10% of any benefit payment; and (c) they are neither for the purpose, nor have the effect, of defraying plan administration costs. An attachment, garnishment, levy, execution, or other legal or equitable process is not considered a voluntary assignment or alienation.

Notwithstanding the prohibitions included in this Section, a Participant or Beneficiary may direct the Plan to pay all or a portion of a Plan benefit to a third party, including the Employer, if: (a) such direction is revocable at any time by the Participant or Beneficiary; and (b) the third party files a written acknowledgment with the Plan Administrator stating that the third party has no enforceable right in, or to, any Plan benefit payment or portion thereof (except to the extent of payments actually received pursuant to the terms of the arrangement). This acknowledgment must be filed with the Plan Administrator no later than 90 days after the arrangement is entered into. A blanket written acknowledgment for all Participants and Beneficiaries who are covered under the arrangement with the third party is sufficient.

Notwithstanding the prohibitions included in this Section, a Participant’s benefit may be used to offset an amount that the Participant is ordered or required to pay to the Plan or under an order of forfeiture or restitution provided that such order complies with applicable law, including an order under the Mandatory Victims’ Restitution Act.

19.02 Qualified Domestic Relations Orders. Section 19.01 shall also apply to the creation, assignment or recognition of a right to any benefit payable with respect to a Participant pursuant to a domestic relations order, unless such order is determined to be a Qualified Domestic Relations Order. A Qualified Domestic Relations Order may not require the Plan to provide any form of benefit not allowed under Article XII, may not increase benefits, and may not alter the payment of benefits under an existing Qualified Domestic Relations Order. In the case of any payment before a Participant has separated from Service, a Qualified Domestic Relations Order shall not be treated as providing a benefit not allowed by the Plan solely because the order requires payment of benefits to an Alternate Payee on or after the date on which the Participant attains (or would have attained) the “Earliest Retirement Age” as if the Participant had retired on that date and in any form allowed by the Plan. “Earliest Retirement Age” shall mean the earliest date on which the Participant could begin receiving benefits under the Plan if the Participant separated from Service.

When a domestic relations order is received by the Plan, the Plan Administrator shall promptly notify the Participant and any Alternate Payee of the receipt of such order and the Plan’s procedures for determining if the order is a Qualified Domestic Relations Order and, within a reasonable time, the Plan Administrator shall determine if such order meets these requirements.

44

The Plan Administrator shall notify the Participant, the Alternate Payee and any other person specified in the order as being entitled to payment of benefits under the order at the address specified in the order of its determination. An Alternate Payee may designate a representative for receipt of copies of such notices. Unless distributions were being currently made, no distributions of benefits shall occur while this determination is being made by the Plan Administrator. If distributions were occurring prior to receipt by the Plan Administrator of the order, a separate account shall be established to hold any further distributions until a final determination is made by the Plan Administrator.

Upon written receipt of a domestic relations order, the Plan Administrator shall review this order, inform the Trustee, and gather such facts as it may deem appropriate. The Plan Administrator may consult with legal counsel for the Plan in such matters. The Plan Administrator shall reach a decision within 18 months following the date on which the first payment would be required to be made under the order whether it is a Qualified Domestic Relations Order. During this period the Plan Administrator shall separately account for the amounts which would have been payable to the Alternate Payee during the period if the order had been determined to be a Qualified Domestic Relations Order. If the order (or modification thereof) is qualified, the segregated amounts shall be paid according to the order. If the order is not qualified, any segregated accounts plus earnings thereon shall be returned to their original account. If the Plan’s Fiduciaries follow these procedures, the Plan and all Fiduciaries shall be relieved of any liability to any Participant or Alternate Payee. If an order is subsequently found to be a Qualified Domestic Relations Order, all payments shall be prospective only.

ARTICLE XX

DESIGNATION AND STATUS OF TRUSTEE

20.01 Trustee Appointment/Resignation and Removal. The Sponsor has by the execution of this Plan and Trust Agreement appointed the Trustee named herein. The Trustee may resign upon 60-days’ notice to the Plan Administrator unless a shorter period is agreed to by the Plan Administrator. The Trustee may be removed upon 60-days’ notice unless a shorter period is agreed to by the Trustee. In the event of a resignation or removal of the Trustee, the Sponsor shall designate and appoint a qualified successor. Any such successor Trustee shall have all of the powers, duties and authority herein conferred upon the original Trustee. Upon acceptance of such appointment by the successor Trustee and the submission to the successor of a detailed and accurate accounting, the resigning or removed Trustee shall assign, transfer and pay over to the successor Trustee the funds and properties then constituting the Trust Fund.

20.02 Directed Trustee. As to the assets comprising the Plan, the Trustee shall serve as a directed trustee hereunder. Notwithstanding any provision of this Plan to the contrary, the power and authority afforded to the Trustee hereunder with respect to such assets shall be interpreted and construed in a manner consistent with such designation.

45

ARTICLE XXI

POWERS AND RIGHTS OF TRUSTEE

21.01 General Powers and Authority. Except as otherwise herein expressly provided, the administration and management of the Trust herein created, the sale and conveyance of the Trust assets and the investment and reinvestment of Trust assets by the Trustee shall be performed in accordance with the directions of the Investment Committee and the Participants. The rights, powers, duties and liabilities of the Trustee shall be in accordance with and governed by the terms and provisions of the laws of the State of Mississippi governing fiduciary rights and responsibilities. However, in addition to the powers provided under such laws, the Trustee, shall have full power and authority at the direction of the Investment Committee and the Participants to perform the following:

46

The Trustee is not authorized to accomplish any act for the Trust which would constitute a prohibited transaction unless exempted by the Department of Labor. A prohibited transaction shall include any direct or indirect sale or exchange or leasing of any property; lending of money or other extension of credit; or furnishing of goods, services or facilities between a plan and a disqualified person. A prohibited transaction shall also include the transfer of the income or assets of the Plan to a disqualified person; the use of the income or assets of the Plan by or for the benefit of a disqualified person; or the dealing with the income or assets of the Plan in the Trustee’s own interest or for the Trustee’s own account.

21.02 Adoption of Procedures. The Trustee may adopt such rules of procedure as in its discretion it deems necessary for a proper and efficient maintenance of the Fund and shall keep and maintain records of its proceedings and acts.

21.03 Defense of Legal Actions. If any Participant or Beneficiary brings legal action against the Trust, the result of which shall be adverse to the party bringing suit, or if any dispute shall arise as to the person or persons to whom payment or delivery of any funds shall be made by the Trustee, the cost to the Trust of defending such suit may be a lien against the account of the Participant whose interest is in issue if the Participant is given prior notice of an impending lien and there is a judicial hearing on the probable validity of the Trustee’s claim.

21.04 Costs of Administration. The Trustee is authorized to pay from the Fund all expenses, taxes and charges, including fees of attorneys or agents, incurred in connection with the administration or operation of the Fund. The Trust shall pay the Trustee such reasonable compensation as shall be agreed upon from time to time by the Sponsor and the Trustee, unless the Employer shall assume such obligation.

47

Where paid from the Trust Fund, an expense generally shall be allocated pro rata to all Participants in the Plan provided, however, any fee determined on a per Participant basis, such as, by way of example, a recordkeeping fee, shall instead be charged to the accounts of Participants on a per capita basis. Further, so long as not precluded by ERISA, the Code, regulations or governing authority, any expense generated by or attributable to only one or some, but not all Participants shall be charged solely to the account or accounts of the affected Participants, provided that such is done in a uniform or non-discriminatory manner, including, by way of example, fees attributable to processing distributions, obtaining a loan or hardship distribution or the determination as to whether a domestic relations order constitutes a QDRO and, if so, the processing and administration of that QDRO.

21.05 Bond Requirement. Unless required by ERISA, the Trustee shall not be required to give bond for the faithful performance of its duties hereunder.

21.06 Consultation with Legal Counsel. The Trustee may consult with counsel, who may be counsel for the Sponsor, with respect to any of its duties or obligations hereunder and may rely on counsel in acting or refraining from acting in accordance with their advice.

21.07 Reliance on Instructions. The Trustee shall be fully protected in taking any action (at the direction of the Investment Committee and/or a Participant) indicated by this instrument to be within the scope of the authority of any officer of the Sponsor or of the Board of Directors in accordance with any written instrument purported to be signed by such individual, or in reliance upon a certified copy of a resolution of the Employer which the Trustee, in good faith, believes to be genuine.

21.08 Employment of Fiduciaries/Investment Managers. The Trustee may employ such Fiduciaries as the Investment Committee designates. In accordance with the provisions of Section 402(c)(3) et. seq., of ERISA, the Investment Committee may appoint one or more Investment Managers to manage all or part of the assets of the Plan. An Investment Manager appointed under this Section must be (a) registered as an investment advisor under the Investment Advisors Act of 1940, (b) a bank as defined in that Act, or (c) an insurance company qualified to manage, acquire or dispose of assets of a plan under the laws of more than one state. If this election is made, the Investment Committee shall direct the Trustee, by written notice, to segregate any portion or portions of the Trust in a separate account or accounts to be invested and reinvested by the Investment Manager, pursuant to Section 21.01. The following provisions shall be applicable:

48

The Trustee shall have no liability or responsibility for acting pursuant to the direction of, or failing to act in the absence of any direction from, the Investment Manager, unless the Trustee knows that by such action or failure to act it would be itself committing or participating in a breach of fiduciary duty by the Investment Manager.

21.09 Participant Directed Investments. Each Participant shall be allowed to control and direct the investments of all of the Participant’s accounts pursuant to Section 404(c) of ERISA. All investment options shall be selected by the Investment Committee. The Investment Committee shall select a diversified group of investments or Investment Managers to offer to the Participants. Such funds and managers shall be the only investment options available (other than Employer Stock) and shall include at least three (diversified categories of investments). The categories of investments shall be diversified both between categories and within each category and shall meet the requirements of Section 2550.404c-1 of the Department of Labor Regulations. Information regarding the categories of investments shall be made available to the Participants by the Investment Committee.

All initial investment directions shall be made in a method accepted by the recordkeeper. All assets acquired pursuant to such direction shall be held by the Trustee until distributed in accordance with the terms of the Plan, or until the Participant directs that they be disposed of.

49

The Trustee is obligated to follow these instructions, but shall not implement any investment decision of the Participant which would create taxable income to the Plan. The Trustee and the Investment Committee shall not be liable for any loss, or by any reason of any breach, which results from the Participant’s controlling and directing investments in his or her account or accounts, and shall not be under any duty to advise a Participant or Beneficiary with respect to any investment.

Each Participant shall be informed of his or her rights to direct the investment of his or her accounts and of the procedures regarding directed investments. If the Participant does not elect an investment method, his or her accounts shall be invested in a default fund selected by the Investment Committee.

ARTICLE XXII

TRUSTEE’S ACCOUNTINGS

22.01 Trustee’s Records. The Trustee shall keep accurate and detailed accounts of all investments, receipts, disbursements and other transactions hereunder. All accounts, books and records relating thereto shall be open to inspection and audit at all reasonable times by any person designated by the Investment Committee or by the Plan Administrator.

22.02 Valuation of Trust Assets. Net Earnings of the Fund shall be computed by the Trustee’s agent (as designated in writing by the Trustee) as of each Valuation Date and the agent’s good faith decision as to the value of the Fund and the Net Earnings and adjustments thereof shall be final, conclusive and binding upon all Participants and Beneficiaries.

If Employer Stock held in the Trust is not “readily tradable on an established securities market” (as defined in Section 24.01), and to the extent applicable, all valuations of Employer Stock acquired by or contributed to the Plan with respect to the activities carried on by the Plan shall be performed by an independent appraiser. For the purposes of the preceding sentence, the term “independent appraiser” means any appraiser meeting the requirements of Section 401(a)(28)(C) of the Code.

22.03 Annual Accounts. Within 90 days following the close of each Plan Year and within a like period of time after its removal or resignation, the Trustee shall file with the Investment Committee or the Plan Administrator an accounting setting forth all investments, receipts, disbursements and other transactions effected by it during such Plan Year, or during the period from the close of the last Plan Year to the date of such removal or resignation. The accounting shall set forth the current fair market value of the Trust as of the date of the accounting. Securities held in the Trust shall be valued as of the close of business on the last business day of the Plan Year (or other closing date) on which those securities were traded. The market value of all other assets shall be fixed on the same date in such manner as the Trustee deems necessary.

22.04 Participant Statements. Any Participant or Beneficiary may request in writing a statement indicating on the basis of the latest available information the total benefits accrued and the nonforfeitable benefits, if any, which have accrued, or the earliest date on which benefits will become nonforfeitable. No Participant or Beneficiary shall be entitled to receive more than one statement during any one 12-month period.

50

22.05 Right to Compel Accounting. No Participant, Beneficiary, estate or other person interested in the Trust, except the Investment Committee or an Employer, shall have the right to compel an accounting by the Trustee, judicial or otherwise, except as stated above. All such persons shall be bound by all accountings by the Trustee to the respective Employers, including accountings rendered to the Employer after a Participant’s termination of employment, Disability or death.

ARTICLE XXIII

QUALIFIED MILITARY SERVICE

23.01 Applicability. This Article XXIII applies to an Employee who: (1) has completed Qualified Military Service under USERRA; (2) the Employer has rehired under USERRA or who died while in Qualified Military Service; and (3) who is a Participant entitled to make-up contributions under Section 414(u) of the Code.

23.02 Compensation. For purposes of this Article XXIII, the Plan Administrator will determine an affected Participant’s Compensation as follows. A Participant during his or her period of Qualified Military Service is deemed to receive Compensation equal to that which the Participant would have received had he or she remained employed by the Employer, based on the Participant’s rate of pay that would have been in effect for the Participant during the period of Qualified Military Service. If the Compensation during such period would have been uncertain, the Plan Administrator will use the Participant’s actual average Compensation for the 12-month period immediately preceding the period of Qualified Military Service, or if less, for the period of employment.

23.03 Make-Up of Elective Deferrals. The Plan Administrator shall allow a Participant under this Article XXIII to make up Elective Deferrals to his or her Elective Deferrals Account. The Participant may make up the maximum amount of Elective Deferrals which he or she would have been able to contribute during the period of Qualified Military Service (less any such amounts the Participant actually contributed during such period) and the Participant must be permitted to contribute any lesser amount as the Plan would have permitted. The Participant must make any make-up contribution under this Section 23.03 commencing on his or her reemployment date and not later than five years following reemployment (or if less, a period equal to three times the length of the Participant’s Qualified Military Service triggering such make-up contribution).

23.04 Make-Up Matching Contributions. The Employer shall make up any Matching Contribution that the Employer would have made and which the Plan Administrator would have allocated to the Participant’s Account during the period of Qualified Military Service based on any make-up Elective Deferrals that the Participant makes under Section 23.03.

23.05 Limits on Make-Up Contributions. Any contribution made under this Article XXIII does not cause the Plan to violate nor be subject to: (1) nondiscrimination testing, including under the ADP test, the ACP test and Section 401(a)(4) of the Code; (2) top-heavy

51

rules under Section 416 of the Code; or (3) coverage under Section 410(b) of the Code. Contributions under this Article XXIII are Annual Additions and are subject to the deferral limits under Section 5.06 for the year to which such contributions are allocated, but not for the year in which such contributions are made.

23.06 No Make-Up Earnings. A Participant receiving any make-up contribution under this Article XXIII is not entitled to an allocation of any earnings on any such contribution prior to the time that the Employer actually makes the contribution to the Trust Fund.

23.07 No Forfeitures During Leave. A Participant receiving any make-up contribution under this Article XXIII is not entitled to an allocation of any forfeitures arising during the Participant’s period of Qualified Military Service.

23.08 Other Rights and Benefits. In the event a Participant dies on or after January 1, 2007 while performing Qualified Military Service, the Participant shall be deemed to have been reemployed by the Employer on the date prior to his death for all purposes except the accrual of benefits during the period of Qualified Military Service.

Differential wage payments, if any, will be treated as Compensation under this Article XXIII and for purposes of Employee deferrals and any Employer contributions. Differential wage payments are payments that (a) are made by the Employer to an individual with respect to any period during which the individual is performing services in the uniformed military service, while on active duty for a period of more than 30 days; and (b) represent all or a portion of the wages that the individual would have received from the Employer if the individual were performing Services for the Employer. An individual is treated as having incurred a severance from employment for purposes of this Plan during any period the individual is performing service in the uniformed military service.

ARTICLE XXIV

EMPLOYER STOCK

24.01 Definitions. Unless specifically defined below, capitalized terms used in this Article shall have the meanings otherwise ascribed to them in the Plan.

52

For purposes of this Article XIV, a security is “readily tradable on an established securities market” if the security is:

24.02 Required Investment Option. In addition to any investment fund offered under the Plan from time to time, each Participant shall be permitted to invest and reinvest amounts allocated to his or her accounts in the Qualifying Employer Securities Fund.

24.03 Acquisition and Disposition of Employer Stock.

3.06 Article V is hereby amended by the addition of a new Section 5.12 at the end thereof to read as follows:

5.12 Excess Elective Deferrals. A Participant may assign to the Plan the amount of any Elective Deferrals in excess of the amount allowed pursuant to Section 5.07 and, if applicable, Section 5.08, during a taxable year of the Participant (“excess Elective Deferrals”) by notifying the Plan Administrator of the amount of the excess Elective Deferrals to be assigned to the Plan.

Distribution of excess Elective Deferrals shall be made first from the Participant’s pre-tax Elective Deferral account to the extent pre-tax Elective Deferrals were made for the year, unless the Participant specifies otherwise.

The income or loss allocable to excess Elective Deferrals distributed under this Section is the income or loss allocable to the Participant’s Elective Deferral Account for the taxable year multiplied by a fraction, the numerator of which is such Participant’s excess Elective Deferrals for the year and the denominator of which is the sum of the Participant’s Elective Deferral Account balance as of the beginning of the taxable year plus the Participant’s Elective Deferrals for the taxable year. No income or loss will be credited to any excess Elective Deferrals for the period between the end of the taxable year and the date of distribution (the gap-period) of such excess Elective Deferrals. No distribution of excess Elective Deferrals shall be made during the taxable year of a Participant in which the excess Elective Deferral was made unless the correcting distribution is made after the date on which the Plan received the excess deferral and both the Participant and the Plan designate the distribution as a distribution of an excess Elective Deferral.

3.07 Section 11.06 is hereby amended by the deletion of the third and fourth paragraphs of that Section and the substitution of the following:

Before a Participant can receive a hardship distribution under this Section, such Participant must have obtained all distributions (other than hardship distributions) and all nontaxable loans (other than hardship loans) currently available under all plans maintained by the Employer, including a request for dividend distribution. A Participant who makes a hardship distribution request under this Section 11.06 and who has previously elected (or is deemed to have previously elected) reinvestment of Designated Dividends in the Qualifying Employer Securities Fund in accordance with Section 24.11, shall be deemed to have affirmatively elected to receive Designated Dividends in cash on the date the hardship distribution is made. The Participant’s election to receive Designated Dividends in cash shall remain in effect until the Participant subsequently makes an affirmative election otherwise in accordance with Section 24.11(a).
