Enrolling for Coverage

The enrollment materials you will receive from the Lockheed Martin Employee Service Center (LMESC) include detailed instructions on how to enroll and the resources available to you in the event you have questions.

You must enroll in Long-Term Disability insurance if you want coverage. If you do not enroll when you are first eligible and later decide to enroll, you will be required to provide satisfactory Proof of

Insurability (POI) before you can be covered. Refer to the “When Coverage Begins” section for more information on enrollment timeframes.

Cost of Coverage

You pay the full cost of Long-Term Disability insurance. The cost is automatically deducted on an after-tax basis from your paycheck each pay period. Consequently, your Long-Term Disability insurance benefit is tax-free when you receive it.

(7)

When Coverage Begins

Subject to all plan provisions and proper enrollment, the chart below explains when Long-Term Disability coverage becomes effective.

When You Enroll Your Coverage Becomes Effective*

Within 30 days of your initial eligibility date** When you enroll within 30 days of your first day of work or the date you become an eligible employee, coverage for you becomes effective the day you enroll

After 30 days of your first day of work (or the date

you become eligible) On the day your Proof of Insurability (POI) is approved by the insurance company During an Annual Enrollment period On the later of the first day of the following Plan

Year or when your POI is approved by the insurance company

* If you are not Actively at Work on the day coverage would otherwise begin, coverage becomes effective on the first day that you return to Active Service.

** Your first day of work or the first day you meet the eligibility requirements is considered your initial eligibility date for coverage.

Changing Your Elections During the Plan Year

If you wish to make a change during the Plan Year, you may do so by visiting the Lockheed Martin Employee Service Center Online (LMESC Online) or by calling the Lockheed Martin Employee Service Center (LMESC).

You may enroll in or cancel Long-Term Disability insurance at any time during the Plan Year. If you are enrolling for or increasing coverage amounts, all plan requirements (for example, Proof of Insurability [POI]) will apply.

The Long-Term Disability coverage option in effect immediately prior to your request to increase coverage remains unchanged until POI is approved by the LTD Insurance Carrier.

When Proof of Insurability (POI) Is Required

(8)

How POI Works

Proof of Insurability (POI) is the process that the insurance company uses to determine if you are insurable for Long-Term Disability insurance. When POI is required, you must provide a statement of your health history. If you elect an option that requires POI, you will automatically receive a form that must be completed and returned. The necessary form also is available by calling the Lockheed Martin Employee Service Center (LMESC) and speaking directly with a Customer Representative. The insurance company may also ask you for other evidence of good health, such as a medical examination. The POI or other evidence of good health must be acceptable to the insurance company in order for your coverage (or increase in coverage) to take effect.

How the Long-Term Disability (LTD) Plan

Works

The LTD plan provides income replacement if you become disabled because of a covered sickness or injury. This coverage includes:

 Replacement of a percentage of your Annual Base Pay if you become disabled due to a covered sickness or injury. A sickness or injury is covered as long as it does not result from any of the exclusions listed in the “What Is Not Covered” section.

 Benefits that begin after you have been disabled for a certain amount of days (subject to all plan provisions).

 Survivor benefits if you die while receiving benefits.

Defining Disability

To qualify for Long-Term Disability benefits, you must be considered Disabled. You are Disabled if, because of sickness or injury:

 You are unable to perform each and every material duty of your regular occupation; and

_{After monthly benefits have been payable for 24 months, you are unable to perform each and every} material duty of any occupation for which you may reasonably become qualified based on education, training or experience.

Sickness means physical or mental illness and also includes pregnancy. Injury means an accidental loss or bodily harm.

The Long-Term Disability Insurance Carrier will determine whether your sickness or injury meets the definition of disability. You may be asked to provide proof of your continuing disability from time to time – for example, through a medical examination – at your own expense.

Benefit Amount

The amount of your benefit depends upon the coverage option you choose and your Annual Base Pay, which is determined as of the later of December 1 of the prior plan year or your date of hire. The benefit amount for which you are eligible (and the cost of your coverage) will not change during a plan year, regardless of any salary changes you may experience. However, if the salary change results from a change in employment status between full-time and part-time, your annual base pay (and your benefit amount and cost of coverage) will be predetermined as of the date of the change. See the “Your LTD Summary of

Benefits” table for specific benefit amounts.

No change in your Annual Base Pay will be taken into account in determining the amount of your LTD insurance benefit (or the cost of your coverage) if the change occurs:

 During a benefit waiting period;

 While you are actively at work between separate periods of disability that are considered one period; or

(10)

Benefits are prorated for any period of disability that lasts less than a whole month.

Benefit Waiting Period

Before Long-Term Disability benefits begin, you must satisfy a Benefit Waiting Period (as noted in the

“Your LTD Summary of Benefits” table). You must be under the care of a physician during this time.

The date Long-Term Disability insurance benefits begin depends on specifications noted in the “Your

LTD Summary of Benefits” table.

Benefit Limitations

The Long-Term Disability insurance company will pay a maximum of 24 monthly benefits in a lifetime for a disability caused or contributed by one of the following mental illnesses or substance abuse:  Alcoholism;

 Anxiety disorders;

 Delusional (paranoid) disorders;  Depressive disorders;

 Drug addiction or abuse;  Eating disorders;

 Mental illness; or

 Somotaform disorders (psychosomatic illness).

Note: If you are confined in a hospital for more than 14 consecutive days before reaching your lifetime maximum benefit, any disability benefits paid during that confinement will not count against the lifetime maximum benefit.

Successive Disability Rule

If you return to active service and become Disabled again from the same sickness or injury within the time period specified in the “Your LTD Summary of Benefits” table, your disability will be considered continuous, and your benefits will begin again without another benefit waiting period.

You will be considered to have a separate disability and have to begin a new benefit waiting period if:  You become Disabled again from causes unrelated to your first Disability, and you have returned to

active service for a certain period of time; or

 The Disability results from the same sickness or injury but you returned to work for a certain period of time; or

Coverage

Definition of Earnings _{Your Annual Base Pay, as of December 1st of the} prior plan year, excluding lump sum merit increases, incentive compensation, commissions, night shift bonuses, overtime, other bonuses, and other compensation; or your date of hire. If you are a part-time employee, your Annual Base Pay is based on 30 hours per week. Consequently, the benefit amount for which you are eligible (and the cost of your coverage) will not change during a plan year, regardless of any salary changes you may experience. However, if the salary change results from a change in employment status between full-time and part-time, your Annual Base Pay (and your benefit amount and cost of coverage) will be redetermined as of the date of the change. No change in your Annual Base Pay will be taken into account in determining the amount of your Long-Term Disability insurance benefit (or the cost of your coverage) if the change occurs:

_{During a benefit waiting period;}  While you are actively at work between

separate periods of disability that are considered one period; or

_{While you are Disabled.}

Benefits are prorated for any period of disability that lasts less than a whole month. Your benefit will be paid to you; survivor benefits will be paid to your eligible survivors.

Elimination/Waiting Period _{180 calendar days of disability (beginning with} your first day of disability). You must be under the care of a physician during this time. If during this waiting period you return to work in your regular occupation for up to 30 days (up to 90 days if you are covered under a Company short-term disability policy) and again become Disabled from the same sickness or injury, you do not need to restart your benefit waiting period. Your disability is considered continuous. However, the benefit waiting period will be extended by the number of days you are back at work.

(13)

Coverage

Successive Disability Rule _{Within six months of the date of your return to} work, your disability will be considered continuous, and your benefits will begin again without another benefit waiting period. You will be considered to have a separate disability (and have to begin a new benefit waiting period) if:  You become Disabled again from causes

unrelated to your first disability and you have returned to active service for at least one full day;

 The disability results from the same sickness or injury but you returned to work for six consecutive months, or more; or

_{The later disability occurs after coverage} under this insurance ends.

Survivor Benefit _{If you die after you have been receiving monthly} benefits for at least six months and are receiving benefits at the time of your death, your eligible survivor may receive a survivor benefit. The survivor benefit will equal the last full monthly benefit you received before your death, plus any amount by which that benefit had been reduced because of wage or profit from work performed. This benefit will be paid each month for six months after your death.

Taxes _{You pay the full cost of Long-Term Disability}

insurance. The cost is automatically deducted on an after-tax basis from your paycheck each pay period. Consequently, your Long-Term Disability insurance benefit is tax-free when you receive it. Proof of Insurability _{Required if you elect coverage more than 30 days}

after your initial eligibility date, if you want to increase the amount of coverage you initially elected, or if you drop coverage and re-enroll at a later date. The Long-Term Disability coverage option in effect immediately prior to your request to increase coverage remains unchanged until POI is approved by the insurance carrier.

Other Benefits

Rehabilitation Plan Program

(14)

education expenses, accommodation expenses or family care expenses while you participate in the program. A rehabilitation plan is a written agreement between you and the Long-Term Disability

insurance company in which the insurance company agrees to provide, arrange or authorize vocational or physical rehabilitation services. You and the Long-Term Disability Insurance Carrier must agree to the terms and conditions of the rehabilitation plan.

Cost-of-Living Adjustment

After you have received benefit payments for 12 consecutive months, you will receive a three percent annual Cost-of-Living Adjustment (COLA) – up to a maximum of 10 annual increases. The COLA increase date is January 1st.

This COLA benefit does not apply to the minimum or maximum benefit or to the formula used to determine benefits under the work incentive provision.

Pre-existing Condition Limitation

The plan will not pay Disability benefits for any period of Disability caused or contributed by or resulting from a pre-existing condition. A “pre-existing condition” includes any injury or sickness for which you incurred expenses, received medical treatment (including diagnostic measures), took prescribed drugs or medicines or for which a reasonable person would have consulted a Physician. Under the coverage maximums, there are two pre-existing condition limitations depending on your maximum covered benefit amount:

Coverage option Pre-existing condition limitation if your Annual Base Pay is $200,000 or less

Pre-existing condition limitation if your Annual Base Pay is between $200,001 and $600,000

50% For covered monthly benefit amounts up to $8,333, the Disability will not be covered if it begins during the first 12 months after your coverage (or increase in coverage) becomes effective and is caused or contributed by or results from a pre-existing condition you had during the three months before your coverage (or increase in coverage) became effective.

For covered monthly benefit amounts from $8,334 to $25,000, the Disability will not be covered if it begins during the first 12 months after your

coverage (or increase in coverage) becomes effective and is caused or contributed by or results from a pre-existing condition you had during the 12 months before your coverage (or increase in coverage) became effective.

60% For covered monthly benefit amounts up to $10,000, the Disability will not be covered if it begins during the first 12 months after your coverage (or increase in coverage) becomes effective and is caused or contributed by or results from a pre-existing condition you had during the three months before your coverage (or increase in coverage) became effective.

For covered monthly benefit amounts from $10,001 to $30,000, the

Disability will not be covered if it begins during the first 12 months after your coverage (or increase in

Work Incentive

You may be eligible for a benefit under this provision if, while you are receiving Disability benefits and under the care of a Physician, you return to your regular job on a part-time basis or to any other

occupation on a full-time or part-time basis. The amount of your benefit under this provision is determined using your Indexed Annual Base Pay.

Your benefit under the work incentive provision will equal

For the first 12 months after you return to work Either 50% or 60% of your Annual Base Pay (reduced by any other income benefits* you receive).

If the sum of your monthly Disability benefit, current Earnings** and any other income benefits* exceeds 100% of your monthly Indexed Annual Base Pay for any month during this period, your benefit will be reduced by the excess amount.

After 12 months Either 50% or 60% of your Annual Base Pay

(reduced by both any other income benefits* you receive and by 50% of current Earnings** you receive during any month you return to work). If for any month the sum of your monthly Disability benefit, current Earnings** and any other income benefits* exceeds 80% of your monthly Indexed Annual Base Pay, your benefit will be reduced by the excess amount.

* Any benefits listed under “Benefit Reductions” that you receive on your own behalf or on behalf of your dependents or that your dependents receive because of your entitlement to other income benefits. ** Any wage or salary for work performed while Disability benefits are payable. If you are working regularly for another employer when Disability begins, current Earnings will include any increase in the amount you earned from this work during the period for which Disability benefits are payable.

Benefit Reductions

The amount of your benefit payments from the Long-Term Disability insurance company will be reduced by any other income benefits that you receive on your own behalf or on behalf of your dependents or that your dependents receive because of your entitlement to other income benefits. Other Income Benefits include:

 Any amounts you or your dependents, if applicable, receive (or are assumed to receive*) under: • The Canada and Quebec Pension Plans;

• The Railroad Retirement Act;

• Any local, state, provincial or federal government disability or retirement plan (except military retirement) or law;

(16)

• Any disability benefits received from the Veterans' Administration for a disability for which you are eligible to receive a benefit under your disability plan; or

• Any workers' compensation, occupational disease, unemployment compensation law or similar state or federal law, including all permanent as well as temporary disability benefits. This includes any damages, compromises or settlement paid in place of such benefits, whether or not liability is admitted.

_{Any Social Security disability or retirement benefits you or any third party receive (or are assumed to} receive) either on your behalf or for your dependents; or, if applicable, which your dependents receive (or are assumed to receive) because of your entitlement to such benefits.

 Any retirement plan benefits funded by your Employer. “Retirement plan” means any defined benefit or defined contribution plan sponsored or funded by your Employer. A retirement plan does not include the following:

• An individual deferred compensation agreement;

• A profit sharing or any other retirement or savings plan maintained in addition to a defined benefit or other defined contribution pension plan; or

• Any Employee savings plan including a thrift, stock option or stock bonus plan, individual retirement account or 40l(k) plan.

 Any proceeds payable under any franchise or group insurance or similar plan. If there is other insurance that applies to the same claim for disability, and contains the same or similar provision for reduction because of other insurance, we will pay our pro rata share of the total claim. “Pro rata share” means the proportion of the total benefit that the amount payable under one policy, without other insurance, bears to the total benefits under all such policies.

_{Any wage or salary for work performed, excluding Special Recognition Awards (SRA), Spot Awards} and MICP Awards. If Work Incentive Benefits apply to you, we will only reduce your Disability Benefits to the extent provided under your Work Incentive Benefit.

The Long-Term Disability Insurance Carrier will assume that you are receiving the other income benefits for which you and your dependents are eligible and will automatically reduce your benefits by those amounts.

However, if you provide proof that you have applied for full benefits and that payments were denied, benefits will not be reduced for that other benefit. If payments were denied solely because the Disability was not expected to last at least 12 consecutive months, the Long-Term Disability Insurance Carrier will assume that you have begun receiving such benefits after your Disability was continued for 12

consecutive months (unless you provide proof that you re-applied and were again denied payments). If you receive any other income benefits as a lump sum, your benefit will be adjusted as if the lump sum was paid in monthly amounts pro-rated over the period for which the sum is given. If no time span is specified, then the lump sum will be pro-rated monthly over a five-year period.

No matter how much your benefit may be reduced by other income benefits, you will always receive the minimum Disability benefit.

Recovery of Overpayment

If you are paid more than your monthly benefit (including any retroactive lump sum payment), the insurance company has the right to recover the overpayment either by:

(17)

What Is Not Covered

No Long-Term Disability benefits will be paid for:  Any disability that results, directly or indirectly, from:

• Attempted suicide, or injuries intentionally self-inflicted while sane or insane; • Active participation in terrorism or a riot; or

• Commission of a felony;

_{Revocation, restriction, or non-renewal of your license, permit, or certification necessary to perform} the duties of your occupation unless solely due to sickness or injury otherwise covered by the plan; _{A disability that is caused, or contributed to, by a pre-existing condition;}

_{Any disability for which you are not under the care of a legally qualified physician;}

_{Any disability while you are incarcerated for any reason in a penal or correctional institution; or} _{Any disability while you are serving on fulltime active duty in the armed services.}

Duration of Long-Term Disability Benefits

Your Long-Term Disability benefits will end on the earliest of the following:

 The date the Long-Term Disability Insurance Carrier determines you are no longer Disabled;  The date you return to active service;

 The date the maximum benefit period ends;

 The date you earn more than 80% of your annual base pay when you return to work; or  The date you die.

As long as you remain Disabled, you may receive benefits up to the maximum duration shown in the

“Your LTD Summary of Benefits” table.

Survivor Benefit

If you die after you have been receiving monthly benefits for at least six months and are receiving benefits at the time of your death, your eligible survivor may receive a survivor benefit. The survivor benefit will equal the last full monthly benefit you received before your death, plus any amount by which that benefit had been reduced because of wage or profit from work performed. This benefit will be paid each month for six months after your death.

(18)

Situations Affecting Your Coverage

The following chart summarizes how your Plan coverage may be affected in certain situations. If you have any questions about the information in the chart, please contact the Lockheed Martin Employee Service Center (LMESC).

Situation Impact

If you are on medical leave If you are on unpaid family medical leave, you may continue your coverage for up to 12 weeks if you agree to pay any required contributions. If you choose to stop participating, your coverage may be reinstated only if you return to Active Service within 12 weeks from the date your leave began. Reinstated coverage is effective on the date your return to Active Service. If you did not satisfy the pre-existing condition limitation when your leave commenced, you will receive credit for any time that was satisfied before your leave.

When you return to work at the end of your leave, you may resume participating at the same cost if you return during the same Plan Year. If you return to work during a different Plan Year, you must pay the cost in effect for that Plan Year for the coverage level you choose. POI is not required when you resume your participation at the same salary level as when you left.

If you are on personal leave If you are on a personal leave of absence, your coverage continues for up to 31 days. Your cost for coverage will be the same as the active employee cost for coverage, subject to any applicable changes. If your personal leave extends beyond 31 days, you may be eligible to convert coverage after it ends – see “Converting Your Coverage.”

(19)

Situation Impact

If you are on furlough If you are on a furlough, your coverage may continue for up to 90 days. Your cost will be the same as the active employee cost for coverage, subject to any applicable changes, and will be collected from your pay after you return to work. If you do not return to work by the end of your furlough, your benefits will end but you may have the opportunity to continue coverage. You may be eligible to convert coverage after it ends – see

(20)

When Coverage Ends

Your Long-Term Disability coverage ends when:  You are no longer an eligible employee.

 You stop making required contributions (if applicable).  You decline coverage.

 You leave employment at the Company.  The group policy is terminated.

 You retire.  You die.

 The Plan is terminated or amended such that you do not meet the requirement for coverage under the Plan.

Converting Your Coverage When it Ends

You may be eligible for conversion coverage if you have been insured for disability benefits for at least 12 consecutive months under this plan and are actively at work. You will receive general information from the Lockheed Martin Employee Service Center (LMESC). You must apply for conversion insurance within 62 days after your insurance under this plan ends. If you do not do so within the time frame specified, you will forfeit your right to convert.

The conversion plan’s benefits will be those offered by the insurance company at the time you apply. The premium will be based on the rates in effect for conversion plans at that time. Conversion insurance is not available if:

_{You are no longer eligible for this plan but are still employed by the Company;}  You are retired;

_{You are age 70 or older;}

 You are not in active service because you are disabled; or _{The Plan is terminated for any reason.}

(21)

Claims and Appeals Procedures

You or your authorized representative may file a claim for eligibility and/or a claim for benefits. An authorized representative is any person (such as a spouse, parent, medical provider or executor of your estate or attorney) whom you authorize in writing to act on your behalf. The Plan will also recognize representatives authorized through a court order giving a person authority to submit claims on your behalf.

Claims for Eligibility

The Plan Administrator is generally responsible for determining whether someone is eligible for the Plan and for deciding appeals of denied claims involving questions of eligibility to participate in the Plan or changes in coverage elections (these will be referred to as Eligibility Claims). In carrying out these functions, the Plan Administrator has full discretionary authority to interpret and construe the terms of the Plan, to decide questions regarding eligibility for the Plan and to make any related findings of fact. The Plan Administrator can act through its delegate. The decision of the Plan Administrator shall be final and binding to the full extent permitted by law.

Where the claim involves eligibility to participate, you should contact the Lockheed Martin Employee Service Center (LMESC) at:

Lockheed Martin Employee Service Center (LMESC) P.O. Box 199731

Dallas, TX 75219-9731

Claims for Benefits

The LTD Insurance Carrier is responsible for determining whether benefits are payable under the Plan (including, for example, determining whether a claimant is Disabled), determining Proof of Insurability matters, determining the amount of benefits payable, if any, and deciding appeals of denied claims for benefits (these will be referred to as Benefit Claims.

In carrying out these functions, including conducting a full and fair review of denied claims, the LTD Insurance Carrier has the full discretionary authority to interpret and construe the terms of the Plan and to decide questions related to the payment of benefits. The decision of the LTD Insurance Carrier shall be final and binding to the full extent permitted by law.

(22)

Time Frame for Claim Reviews

The Administrator (that is, the insurance carrier or Plan Administrator, as applicable) has 45 days from the date your claim is received to make a decision on the claim. The Administrator may require more time to review your claim, if necessary, due to circumstances beyond its control. If this should happen, the Administrator must notify you in writing before the end of the original period that its review period has been extended for up to two additional periods of 30 days each. If this extension is made because you must furnish additional information, this extension will begin when the additional information is received. You have up to 45 days to furnish the requested information.

Claim Denials

If your claim is denied in whole or in part, you will be notified in writing within the time periods outlined above for the applicable type of claim. The notice will state the following:

 Specific reasons for the denial.

 Plan provisions that support the denial.

 A description of any additional information needed to review your claim request.

 The specific rule, guideline, protocol or other similar criterion or a statement that one was relied on in making the benefit claim denial and that a copy will be provided free of charge upon request.

 A statement that such a rule, guideline, protocol, or other similar criteria was relied upon in making the adverse determination and that a copy of such rule, guideline, protocol, or similar criterion will be provided free of charge upon request.

 If the denial is based on a medical necessity or experimental treatment or similar exclusion or limit, either an explanation of the scientific or clinical judgment for the determination, applying the terms of the Plan to the claimant’s medical circumstances or a statement that such explanation will be provided free of charge upon request.

 Instructions for requesting a review of your claim denial and the applicable time limits, including information regarding your right to bring a civil lawsuit under Section 502(a) of ERISA following a benefit claim denial on review.

Appeals Process

If your claim is denied in whole or in part, you or your authorized representative can request a review of (or appeal) the denied claim within the time limits set forth in this section for the applicable type of claim. The review will take into account all comments, documents, records and other information you submit relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. If you wish, you or your authorized representative may review the

appropriate Plan documents and submit written information supporting your claim to the LTD Insurance Carrier or Plan Administrator.

(23)

Your appeal will be reviewed and the decision made by someone who did not make the initial denial decision and was not a subordinate of someone who made the initial denial decision, and the review will not give deference to the initial decision. In deciding an appeal of any adverse benefit determination based on a medical judgment, a health care professional with appropriate training and experience in the field of medicine involved will be consulted (such health care professional will not be someone who was consulted in connection with the original claim denial or the subordinate of such an individual). Any medical or vocational experts whose advice was obtained on behalf of the plan in connection with an adverse benefit determination will be identified, without regard to whether the advice was relied on in making the initial benefit determination.

Time Limits for Appeals

You or your authorized representative has 180 days from the date you receive the claims denial to make a written request for review of the denied claim (or an appeal) to the insurance carrier or Plan Administrator (where the claim involves “Participation Matters”). If you do not make this request within that time, you will have waived your right to appeal.

The Administrator (the LTD Insurance Carrier or, where the claim involves eligibility or participation, the Plan Administrator) has 45 days from the date your request is received to review your claim and notify you of a decision. Under special circumstances, the Administrator may require more time to review your claim. If this should happen, the Administrator must notify you in writing before the end of the original period that the review period has been extended for an additional 45 days. Once the review is complete, the Administrator must notify you, in writing, of the results of the review and indicate the Plan provisions upon which the decision is based.

Decision on Appeal

If your claim is approved, you will receive the appropriate benefit from the Plan.

If your claim is denied on appeal, in whole or in part, you will receive a written notice from the LTD Insurance Carrier or Plan Administrator within the review period outlined above for the applicable type of claim. The notice will include the following:

 The specific reasons for the decision.

 A reference to the specific Plan provisions upon which the decision is based.

_{A statement that you are entitled to receive, upon request and free of charge, reasonable access to and} copies of all documents, records and other information relevant to your claim for benefits.

_{A statement describing any voluntary appeal procedures offered by the Plan and your right to obtain} these procedures.

_{The specific rule, guideline, protocol or other similar criterion or a statement that one was relied on in} making the benefit claim denial and that a copy will be provided free of charge upon request.

 A statement that such a rule, guideline, protocol, or other similar criteria was relied upon in making the adverse determination and that a copy of such rule, guideline, protocol, or similar criterion will be provided free of charge upon request.

_{If the adverse decision is based on a medical necessity or experimental treatment or similar exclusion} or limit, either an explanation of the scientific or clinical judgment for the determination, applying the terms of the Plan to the claimant’s medical circumstances or a statement that such explanation will be provided free of charge.

Your Rights Under ERISA

As a participant in this Plan, you are entitled to certain rights and protection under the Employee Retirement Income Security Act of 1974 (ERISA). ERISA provides that all plan participants shall be entitled to the provisions stated below.

Receive Information about Your Plan and Benefits

 You are entitled to examine without charge, at the Plan Administrator’s office and at other specified locations, such as work sites and union halls, all documents governing the Plan, including insurance contracts and collective bargaining agreements. You can obtain a copy of the latest annual report (Form 5500 Series) filed by the Plan with the U.S. Department of Labor, which is available at the Public Disclosure Room of the Employee Benefits Security Administration.

 You can obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan, including insurance contracts and collective bargaining agreements, copies of the latest annual report (Form 5500 Series), and an updated summary plan description. The Plan Administrator may make a reasonable charge for the copies.

 You are entitled to receive a summary of the Plan’s annual financial report. The Plan Administrator is required by law to furnish each participant with a copy of this summary annual report.

Prudent Actions by Plan Fiduciaries

In addition to creating rights for plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate your plan, called “fiduciaries” of the plan, have a duty to do so prudently and in the interest of you and other plan

participants and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a benefit or

exercising your rights under ERISA.

Enforce Your Rights

If your claim for a benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge and to appeal any denial, all within certain time schedules.
