ii TO ALL PARTICIPANTS AND ELIGIBLE DEPENDENTS: On September 6, 1966, the Executive Council of The International Association of Machinists and Aerospace Workers established a nationwide Trust Fund known as the IAM National Health and Welfare Plan. On October 1, 1979, it became a part of the National IAM Benefit Trust Fund (Plan) . We are pleased to provide you with this Summary Plan Description (SPD), which describes in detail the benefits available to active and eligible retired employees and their eligible dependents through the National IAM Benefit Trust Fund effective January 2018 . We urge you to read this SPD carefully so that you may fully understand the benefits available to you and your family. We also suggest that you keep this SPD with your important papers so it will be readily available for future reference. Here are some things to keep in mind: This SPD replaces all other SPDs previously published by the Fund. If any changes are made to the Plan’s benefits provisions, they will be communicated to you via a notice that will be sent to the last known mailing address the Fund Office has on file for you. Therefore, it is extremely important that you notify the Fund Office if you change your mailing address. The benefits described in the SPD are not guaranteed (vested). All benefits may be changed, reduced or eliminated at any time by the Board of Trustees, to the extent allowed by law. The Board reserves the right to set the effective date of any Plan change. The information set for th in the SPD is effective for the health and welfare benefits provided by the Plan with respect to all claims incurred on or after January 1, 2018 , unless otherwise stated. The administration of these benefits and accompanying claims is subject to the ter ms of any agreements executed between the Trustees and third - party providers of benefits and or services under the terms of the Plan. The Board solely is authorized to interpret the terms of the Plan and has discretion to decide all questions about the Pl an, including questions about your eligibility for benefits, the amount and type of benefits payable to you, and the application of any Plan term or provision. Your Employer or Union Representative does not have the authority to interpret and/or apply the Plan on behalf of the Board or to act as an agent of the Board. If you have any questions about your benefits, please write or call the Fund Office. Our staff will be pleased to assist you. Sincerely, THE BOARD OF TRUSTEES

iii Welcome! Welcome to your Health and Welfare Plan. We know that your benefits are important to you, and that’s why we work hard to provide you with the best comprehensive, cost - effective, high quality coverage we can. A detailed description of your benefits, beginni ng with your comprehensive medical coverage, is provided in this Summary Plan Description (SPD). Medical, dental and vision benefits are self - funded, which means that health care claims are paid directly from the National IAM Benefit Trust Fund resources rather than an outside insurance company. Your employer contributes to the Benefit Trust Fund on your behalf, according to the terms of your collective bargaining agreement or other participation agreement. Life and accidental death and dismemberment benef its are insured through a contract with a life insurance company ( Cigna ). Summary Plan Descriptions for dental, vision, and short - term disability benefits, and life and accidental death and dismemberment insurance are provided separately if you are eligibl e for such benefits. Being self - funded also means that you have a responsibility to be an informed, conscientious health care consumer. Your individual efforts to conserve Fund resources have a direct effect on the cost of health care benefits provided to you and your family, as well as future benefit availability. It’s in everyone’s best interest to use the savings measures the Trustees have put into place, like using network providers whenever possible, choosing generic medication instead of brand name, a nd taking advantage of preventive car e benefits on a routine basis. This SPD explains the general provisions of the Health and Welfare Plan. It includes legally required notices, an overview of your coverage, information about eligibility requirements for you and your family, claims and appeals procedures, and a glossary of terms used in this SPD . However, this SPD is only a summary of your Plan’s provisions. Full details are contained in the documents that establish the Plan provisions, including the Plan Document. If there is a discrepancy between the wording here and the documents that establish the Plan, the Plan Document language will govern. The Trustees reserve the right to amend, modify or terminate the Plan, and to modify contribution rates at any time and from time to time. If you have any questions about your Plan, the Trustees have authorized the Fund Office to respond in writing to any written questions you may have. In addition, as a courtesy to you, the Fund Office may respond informally to or al questions. However, oral information and answers are not binding on the Trustees and cannot be relied upon in any dispute concerning your benefits. NOTE: Neither the Plan, the Board of Trustees, nor any of their designees are engaged in the practice of medicine or dentistry, nor do any of them have any control over any diagnosis, treatment, care or lack thereof, or any health care services provided to you by any doctor, dentist or other provider. Neither the Plan, Trustees, nor any of their designees wil l have liability whatsoever for any loss or injury caused to you by any doctor, dentist, or provider by reason of negligence, by failure to provide care or treatment, or otherwise.

6 Eligibility Provisions Eligibility for Active Employees You are eligible for coverage if you are an active Employee of an Employer that is participating in the Plan, you are working in a position for which coverage is provided under the terms of the applicable collective bargaining agreement and/or participation agreement, and your Employer is making the required monthly contributions to the Plan on your behalf. Limitations on Eligibility Eligibility under the Plan also is subject to any further requirements and limitations in the applicable collective bargaining agreement or other participation agreement. Whenever the coverage language in the applicable collective bargaining a greement or other participation agreement is inconsistent with the language in this document, the language in the applicable collective bargaining agreement or participation agreement will prevail, provided that language has been accepted by the Fund. Elig ibility While on Leave of Absence Employees who are on an approved leave of absence, where an extension of coverage is being provided under the terms of the applicable collective bargaining agreement and/or participation agreement, are also considered to b e active Employees by the Plan on the condition that the extension of coverage language was approved in advance by the Plan, and the Employer continues to make the required monthly contributions to the Plan on the Employee’s behalf. Temporary Extension of Coverage While Totally Disabled If your medical coverage under the Plan terminates while you are totally disabled, coverage will be extended, only for treatment of that total disability, for three (3) months while you remain totally disabled. In addition, medical coverage for hospital confinement for the disabling condition will be extended until the end of a confinement that begins within three months after your coverage terminated. This extension also applies to your dependent who is totally disabled on the date their coverage terminates. Extension of benefits for total disability will end on the earlier of the following dates: • The date the total disability ends; • The date the person becomes covered under Medicare or any group plan that provides medical benefits; or • Three months from the date the person’s medical coverage terminated. If any applicable extension does not provide uninterrupted coverage to you, you will be notified by the Fund Office that you will be eligible to select COBRA Continuation Co verage under the Plan and make self - payments to continue your coverage. Once you are no longer totally disabled, if you lose coverage, you will be required to satisfy the eligibility rules of the Plan to regain eligibility for benefits. Refer to the Glossa ry for the Plan’s definition of total disability and totally disabled. Eligibility During Family Medical Leave (FMLA) Your eligibility for coverage while on FMLA will be determined by your contributing employer. However, you are eligible for leave under the FMLA if you: • Have worked for a covered employer for at least 12 months; • Have worked at least 1,250 hours over the previous 12 months; and • Work at a location where at least 50 employees are employed by the employer within 75 - mile radius.

7 The Fund Office will maintain your prior eligibility until the end of the leave, provided your contributing employer properly grants the leave under federal law, notifies the Fund, and continues to make monthly contributions on your behalf while you are on an approved le ave. If you and your employer have a dispute over your eligibility under FMLA, your benefits will be suspended pending resolution of the dispute, in the absence of the required contribution. The Board of Trustees will have no direct role in resolving the d ispute. Coverage under this Plan will continue during the FMLA leave on the same basis as other similarly situated employees. Call your employer to determine if you are eligible for the FMLA leave. Then, contact the Fund Office if you are planning to take the FMLA leave so that the Fund is aware of your employer’s responsibility to make contributions during your absence. The Board of Trustees cannot enforce collection of contribution from your employer while you are out on leave; however, federal authoritie s may assist you regarding your continued coverage. Eligibility for Coverage During Leave Under USERRA (Military Leave) If you enter qualified military service (such as active or inactive duty training or active duty in the United States armed forces or Na tional Guard), and you have sufficient hours in previous work periods to continue eligibility for one or more months following the month you enter the Uniformed Services, you have the option of continuing your eligibility in the Plan under the Plan’s Conti nuation of Eligibility rules or freezing your eligibility as of the end of the month in which you enter the Uniformed Services, or as of the date you enter the Uniformed Services if you enter on the first of the month. In addition, you may elect Coverage f or yourself and eligible dependent(s) under COBRA Continuation Coverage. However, in accordance with the Uniformed Services Employment and Reemployment Rights Act (USERRA), you must return to work or seek re - employment with an employer following a discharg e, under not less than honorable conditions, within the minimum time period allowed. If you do not return to work in Covered Employment or seek re - employment in Covered Employment within the minimum time period allowed, you will forfeit your continued eli gibility rights under the Plan. In order to ensure protection of your rights under the USERRA, you must notify the Fund Office as soon as you are called up f or qualified military service. If you are covered under the Plan at the time your qualified milita ry service leave begins, your health coverage will be continued by the Fund for your first 30 days of military service providing monthly contributions are made by your Contributing Employer. If you are on uniformed services for more than 30 days, you will be permitted to continue health coverage for yourself 1 and your eligible dependents under the options set forth herein: • Coverage Options for your Eligible dependent(s): Coverage for your eligible dependents may be elected under COBRA Continuation Coverage . You will be required to self - pay for this coverage. In the alternative, coverage may be provided through the military. • Coverage Options for yourself: you may elect coverage under the Plan’s continuation of coverage benefit 2 , and continue coverage for yourself for up to 24 months. However, the right to elect this continuation coverage is available only to you, not your dependents. If you freeze your eligibility at the beginning of your qualified military leave (effective after your automatic 30 - day cov erage) you may reclaim this eligibility when you return to work for an Employer under the criteria set forth in USERRA. You must notify the Fund Office of your selection, i.e., whether you will freeze your eligibility; elect continuation of coverage for yo urself; or elect COBRA coverage for yourself, and/or your Spouse and Eligible Dependent Children. If you do not notify the Fund Office, your eligibility will be automatically extended until it is exhausted. 1 See option to elect coverage for yourself (not your S pouse or eligible dependents) discussed in the SPD. 2 This coverage is similar to, but is not COBRA Continuation Coverage.

8 If you are honorably discharged from the Uniform ed Services, Plan coverage for you, your Spouse and your Eligible Dependent Child will be reinstated on the day you begin work with an Employer participating in the Plan, provided that you comply with the notice on return to work requirements of USERRA. Th ese requirements and additional information on USERRA can be found at the DOL’s website at: http://www.dol.gov/vets/programs/userra/userra_fs.htm . Your right to maintain and reinstate co verage by reason of qualified military service will be administered and interpreted by the Plan in accordance with the requirements of USERRA, employer contributions, if any, credited to you will be kept on the Plan’s records during the qualified military service leave of absence, and your coverage, as well as coverage for your Spouse, and your Eligible Dependent Child will be reinstated, provided you return to work in Covered Employment or seek re - employment with an employer within the time period protecte d under USERRA. Benefits Upon Your Death — Eligibility of Your Surviving Spouse Surviving Spouse coverage is available for existing contributing employers only if the collective bargaining agreement and/or participation agreement provide for Surviving Spou se coverage, and the Employee or Retiree meets any required age and/or years of service rules specified in such agreements at the time of death. To be eligible for Surviving Spouse coverage where provided, the death of an Employee or Retiree must occur whi le eligible for benefits under the applicable Plan, and the Contributing Employer must continue to make the required mont hly contributions to the Plan. There is otherwise no coverage for surviving Spouses under this Plan. However, your covered surviving S pouse and surviving Dependent Children may have rights under this Plan to make payments for continuation of coverage under COBRA as described later in this SPD . In addition, please check your applicable collective bargaining agreement and/or other partici pation agreement and all information provided to you by your employer for more details on whether or not a surviving spouse benefit is available under the terms of the applicable Plan. Eligibility for Your Spouse and Eligible Dependent Children Your elig ible dependents include: • Your Spouse 1 to whom you are legally married pursuant to federal law and with whom you can file an income tax return, until the last day of month in which a divorce, dissolution of marriage, annulment or legal separation is obtaine d. • Your biological children, foster children, children placed for adoption, adopted children, stepchildren, and/or children for whom you or your covered Spouse are; a) legal guardian, or b) required to provide medical coverage under a Qualified Medical Chi ld Support Order (QMCSO), until the last day of the month in which the child reaches age 26. • Unmarried children of any age provided they are incapable of self - sustaining employment because of a physical or mental disability that occurred when they were covered by this Plan and turned age 26 with such disability present. A dependent must qualify as a dependent as set forth either in the Affordable Care Act (ACA) or the Internal Revenue Code (Code), and the contributing Employer must make contributions to the Plan for such coverage, where required. All eligible dependents must complete the enrollment process to ensure coverage. Employees are required to submit a completed eligible dependent certification (EDC) form for any child whose last name differs from the Employee’s last name, for stepchildren, or for other covered children. 1 The term Dependent does not include a Spouse who is on active duty in any armed forces.

9 Adoption and/or placement papers are required for coverage of legally adopted childr en and children placed for adoption . C overage of Stepchildren requires submission of the child’s birth certificate and proof of the Employee’s marriage to the child’s biological or adoptive parent. Coverage of other dependents requires submission of guardi anship papers or other papers confirming the legal relationship between the Employee and child. Employees must provide a marriage certificate to enroll a Spouse. The Fund Office also may ask you for other related information it needs to evaluate the terms of your relationship with a dependent and may periodically request verification of the covered dependent’s status on an ongoing basis. Eligibility for Disabled Children If a dependent child, age 26 or older, is incapable of self - sustaining employment becau se of mental or physical disability, and the child relies on you for more than one - half of his or her financial support and maintenance, and maintains a permanent residence with you during more than one - half of the calendar year, the child’s coverage may b e continued under this Plan if his or her disability began when the child was covered by this Plan, and he or she turned age 26 with the disability. Y ou must submit proof of your dependent child’s disability to the Fund Office no later than 30 days after t he later of; (a) the date of the child’s disability diagnosis, or (b) the date of initial eligibility for coverage under the Plan. You will be asked to provide proof on the continued existence of the disability to the Fund Office periodically (proof may be required more often du ring the first two (2) years). Important Rules for Dependent’s Eligibility The Fund will not provide coverage for other relatives living in your household (e.g., mother, father, siblings, etc.) regardless of whether they are depende nt upon you financially, or for non - biological children living in your household for whom you are not legally responsible. Also note: • If your eligible dependent child is employed and becomes covered under a group health plan connected to his or her employm ent, the plan under which he or she is an employee will be considered the primary plan for coverage. This Plan will be secondary. • In order for adopted children, children placed with you for adoption, or foster children to be considered eligible dependents, you must provide the Fund Office with appropriate legal documentation, satisfactory to the Plan in its sole discretion, such as adoption papers or a court order appointing you as the legal guardian for the child. • In order for a stepchild to be considered an eligible dependent, the Fund requires that the employee provide a copy of the child’s birth certificate and proof of the employee’s marriage to the child’s biological or adoptive parent. The Fund may also require any and all documentation, including pat ernity papers, court order, state order and/or divorce decree setting forth the relationship with the child. • If a dependent Spouse is eligible for benefits under this Plan as an active participant, benefits will be payable for the Spouse first as a partici pant, then as a dependent. In no event will benefits exceed 100% of covered Charges incurred. • If a dependent child loses eligibility status, the child may regain eligibility only by satisfying all of the requirements included in the Plan’s definition of an eligible dependent and these dependent Eligibility Requirements. The Fund Office will require all participants to provide documentation substantiating an individual’s right to status as an eligible dependent. Documentation required by the Fund Office may include: • A marriage certificate (in the English language); • Birth certificate of biological child showing both parents’ names;

10 • Court (legal) documents showing legal guardianship or adoption; • Acknowledgement of paternity; • Receipt of a Qualified Medical Chil d Support Order pursuant to terms of the Fund; or • Notarized affidavits. The date a person becomes a dependent means: • With respect to a newborn child, the date of birth; • With respect to a stepchild , the date of your marriage to your stepchild ’s parent; • Wi th respect to a foster child, the date the child is placed with you for foster care; • With respect to a child named in a QMCSO, the later of the date specified in the court order or the date it is qualified; • With respect to an adopted child, the date of a doption or placement for adoption; or • With respect to a Spouse, the date of the marriage; • With respect to a child for whom you are legal guardian, the date the guardianship papers are signed by the Court. Effective Date of Coverage for Active Employees Your coverage will become effective on the first day of the month in which you become an eligible Employee, you enroll in the Plan, and your Employer contributes to the Fund on your behalf. Effective Date of Coverage for Eligible Dependents On the day you become eligible for coverage under the Plan, your eligible dependents also become eligible, provided they are enrolled in the Plan within 30 days of your eligibility effective date, and meet all the requirements for coverage. If you marry after the date yo u initially become covered under the Plan, your Spouse becomes covered on the day of marriage provided you give the Fund Office timely notice of the marriage, complete the required paperwork within the permissible time period as set forth under the subsect ion “Special Enrollment During Mid - Coverage Period.” If, after the date you initially become covered under the Plan, you have a newborn biological child, an adopted child, a stepchild, a child placed with you for adoption, or a foster child such child will become covered on the date of their birth (for a newborn biological child) or on the date the child is adopted or placed in your home (for step, adopted, or foster children). To ensure a new dependent receives coverage, you must notify the Fund Office wit hin 30 calendar days of the date you acquire a new dependent through marriage, birth, foster placement, or adoption. You must also submit all required paperwork, and your Employer must make the required contribution for dependent coverage (e.g. Employee pl us Spouse, Employee plus children, family). Determination of Eligibility for Coverage Your eligibility for coverage under this Plan is determined each month, based on the contributions received from your employer. After the initial determination of your eligibility, your eligibility and coverage will terminate on the last day of any month in which you no longer qualify as an Employee, and your employer does not remit the required contribution for your coverage.

11 If your coverage terminates because of your death, your dependents will continue coverage as if you had remained a participant until the end of month of your death. After that, your dependents are eligible to elect COBRA Continuation Coverage. Eligibility for Retiree Coverage To be eligible for Reti ree coverage where provided, you must retire from active employment with a participating Employer while you are eligible for benefits under this Plan, and your Employer must continue to make the required monthly contributions to the Plan. Retiree coverage is only available where the collective bargaining agreement and/or participation agreement provide for Retiree health care coverage, and the covered Employee meets the eligibility rules for Retiree coverage under the terms of such agreements. Please be sur e that you and your Medicare - eligible dependents are enrolled for Medicare before your retirement, or as soon as you become entitled to Medicare after retirement. This Plan has a Medicare enrollment provision for Retirees (and certain disabled persons) whi ch requires that you enroll for Medicare when you become entitled. If a participant could enroll for Medicare but neglects to do so, the Plan will administer benefits as the secondary payer, i.e., Medicare as primary, and will reduce medical benefit paymen ts by the amount Medicare would have paid if the person had enrolled (See Coordination of Benefits). Eligibility Pursuant to a Qualified Medical Child Support Orders The Plan is required to recognize Qualified Medical Child Support Orders (QMCSOs). QMCSOs require health plans to recognize state court orders that the Plan finds to be Qualified Medical Child Support Orders, as defined in the Social Security Act, directing a participant to provide health care coverage for dependent children, even if the partic ipant does not have custody of the children. The Plan will honor any medical child support order, which it finds to be a Qualified Medical Child Support Order (QMCSO) under the procedures set forth under the Plan, and as set forth in ERISA. Under federal law, a QMCSO is a child support order of a court or state administrative agency that has been received by the Fund Office, and that: • Designates one parent to pay for a child’s health plan coverage; • Indicates the name and last known address of the parent re quired to pay for the coverage and the name and mailing address of each child covered by QMCSO; • Contains a reasonable description of the type of coverage to be provided under the designated parent’s health care plan or the manner in which such type of cove rage is determined; and • States the period for which the QMCSO applies. An order is not a QMCSO if it requires the Plan to provide any type or form of benefit or any option that the Plan does not otherwise provide. For a state administrative agency order to be a QMCSO state law must provide that such an order will have the force and effect of law, and the order must be issued through an administrative process established by state law. If a court or state administrative agency has issued an order with respect to health care coverage for any of your dependent children, the Plan Administrator will determine if that order is a QMCSO as defined by ERISA, and under the terms of the Plan. The Plan Administrator’s determination will be binding on you, the other paren t, the child and any other party acting on behalf on the child. If an order is determined to be a QMCSO, the Plan Administrator will notify the parents of each child, and advise them of the Fund’s procedures that must be followed to provide coverage to the dependent children. Coverage of the dependent children will be subject to all terms and provisions of the Plan, including any limits on the selection of providers, and requirement for authorization of services, insofar as is permitted by applicable law.

12 No coverage will be provided for any dependent child under a QMCSO unless all of the Plan’s requirements for coverage of that dependent child have been satisfied. Coverage of a dependent child under a QMCSO will terminate when your coverage terminates for any reason, subject to the dependent child’s right to elect COBRA Continuation Coverage (if that right applies). You may obtain a copy of the Plan’s procedures governing QMCSOs without charge from the Fund Office. If you have any questions about QMCSOs con tact the Fund Office. How to Enroll in Coverage Under the Plan You must apply for coverage for yourself and your dependents by completing an enrollment form and providing the completed form to your Employer. Your Employer will process the form and initiat e any necessary payroll deduction, indicate the effective date of coverage, and provide the form to the Fund Office. Coverage for you, your Spouse, and/or Eligible Dependent Children will not be effective until the Fund Office receives and processes the fo rm. Enrollment forms should be received by the Fund Office prior to your initial effective date for coverage. If submission prior to your effective date is not possible, your form must be received by the Fund Office before the end of the initial coverage m onth. If you acquire a new dependent, you should notify your Employer and enroll the new dependent within 30 days to ensure coverage for your dependent. If you do not enroll your dependent within 30 calendar days, unless you experience a special enrollmen t event, enrollment for coverage will be delayed until your Employer’s Open Enrollment period. If your employer does not have an Open Enrollment period, the Fund Office can assign an Annual Enrollment period during which changes will be allowed. Please con tact the Fund Office if you have any questions about when a dependent can be enrolled and the date the individual will qualify as a dependent. If you fraudulently enroll someone who is not eligible for coverage, that person’s coverage will be terminated i mmediately . The Fund has a right to be reimbursed of any claims that were paid based on the fraudulent enrollment. You also may be subject to criminal penalties. Special Enrollment During Mid - Coverage Period If you, your Spouse, or your Eligible Dependen t Children are declining coverage because of other health insurance coverage, in the future you may be able to enroll yourself, your spouse, or your dependents in this Plan, provided you request enrollment within 30 calendar days after coverage under the o ther plan ends. The dependent’s loss of coverage must be due to exhaustion of continuation coverage under another plan, termination resulting from the loss of eligibility under the other plan, termination as a result of increase in cost of coverage under t he other plan, or termination because Employer contributions under the other plan were reduced or terminated. Loss of coverage for this purpose does not include a loss due to the individual or participant’s failure to make payments on a timely basis under the applicable terms, or termination of coverage for cause. If you have a new dependent as a result of marriage, birth, or placement for adoption, you may enroll your new dependent, provided that you request enrollment within 30 days after the marriage, birth, adoption, or placement for adoption. If you fail to enroll your new dependent within the Special Enrollment time period , you may enroll your new dependent during your Employer’s next Open Enrollment period. If your Employer does not have an Open Enr ollment period, the Fund Office can assign an Annual Enrollment period during which changes will be allowed. Please contact the Fund Office if you have any questions about when a dependent can be enrolled and the date the individual will qualify for depend ent coverage under the Plan. A child will be considered placed for adoption when you become legally obligated to support that child, totally or partially, prior to that child’s adoption. If a child placed for adoption is not adopted, all health coverage ceases when the placement ends, and will not be continued. Please contact the Fund Office if you have any questions about Special Enrollment.

14 • The expiration of the applicable Continuation of Coverage period under the Plan, including COBRA Continuation Coverage. Options Under Which Your Covera ge Can Be Extended Coverage During Family and Medical Leave The Family and Medical Leave Act (FMLA) of 1993, (as amended), allows you to take up to 12 weeks of unpaid leave during any 12 - month period due to any of the events listed below, and you have perf ormed at least 1,250 hours over the previous 12 - month period. In addition, you must work at a location where at least 50 employees are employed by the employer within a 75 - mile radius. Eligibility for leave under FMLA will be determined by your contributi ng employer. In determining your continued eligibility for medical coverage benefits during a FMLA leave of absence, the Plan will comply in all respects with the Act. The FMLA allows an Employee to FMLA leave of absence due to: • The birth, adoption, or pla cement with you for adoption or foster care of a child; • You need to care for a seriously ill Spouse, child, or parent; • Your serious illness; • A qualifying exigency, or urgent need to for leave because your Spouse, son, daughter or parent is on active duty in the armed services (including the National Guard or Reserves) in support of a military operation. • In addition, you may be able to take up to 26 weeks of unpaid leave during any 12 - month period to care for a service member. The service member must be:  Your Spouse, son, daughter, parent, or next of kin;  Undergoing medical treatment, recuperation or therapy for a serious illness or injury incur red in the line of duty while in the armed forces; and  As an outpatient or on the temporary disability retired list of the armed services. Co vered service members include veterans who were members of the Armed Forces (including the National Guard or Reserv es) at any time during the 5 years preceding the date on which the medical treatment, recuperation or therapy began. The Fund will maintain your prior eligibility status until the end of the leave, provided the contributing Employer properly grants the le ave under the FMLA, notifies the Fund, and continues to make the required contribution to the Fund. If you and your employer have a dispute over your eligibility under the FMLA, your benefits will be suspended pending resolution of the dispute, in the absence of the required contribution. The Board of Trustee will have no direct role in resolving the dispute. Coverage under the Plan will continue during the FMLA leave on the same basis as othe r similarly situated employees. Call your employer to determi ne if you are eligible for the FMLA leave. Then contact the Fund Office if you are planning to take the FMLA leave so that the Fund is aware of your employer’s responsibility to make contributions during your absence. The Board of Trustee cannot enforce co llection of contributions from your employer while you are out on leave. However, you may seek guidance regarding your continued coverage from the Department of Labor ( DOL), EBSA division. Coverage During Qualified Military Service If you enter qualified m ilitary service (such as active or inactive duty training or active duty in the United States armed forces or national guard), under the Uniformed Services Employment and Reemployment Rights Act (USERRA), your eligibility for coverage under the Plan may be protected during the qualified

15 military service leave of absence. If you have sufficient hours in previous work periods to continue eligibility for one or more months following the month you enter the Uniformed Services, you have the option of continuing your eligibility in the Plan under the Plan’s Continuation of Eligibility rules or freezing your eligibility as of the end of the month in which you enter the Uniformed Services or as of the date you enter the Uniformed Services if you enter on the first o f the month. If you freeze your eligibility you may reclaim this eligibility when you return to work for an Employer under the criteria set forth in USERRA. You must notify the Fund Office of which option you select. If you do not notify the Fund Office, y our eligibility will be automatically extended until it is exhausted. If you are covered under the Plan at the time your qualified military service leave of absence begins, your health coverage will be continued by the Fund during your first 30 calendar da ys of military service. If you are on qualified military leave for more than 30 calendar days, you will be permitted to continue benefits for yourself, or you may opt to freeze your eligibility (as set forth above). The Plan may require you to continued co verage, at your own expense, in premium amounts permitted under COBRA for up to 24 months. If you elect continuation of coverage under the USERRA, this coverage is available only to you , not your Spouse and/or Eligible Dependent Children. Coverage may be a vailable through the military for you, your Spouse, and your Eligible Dependent Children. In order to preserve your eligibility under the Plan, in accordance with USERRA, you must return to work or seek re - employment with an employer following a discharge , under not less than honorable conditions, within the minimum time period allowed. If you do not return to work in Covered Employment or seek re - employment in Covered Employment within the required time period, you will forfeit your continued eligibility rights. In order to ensure protection of your rights under the USERRA, you must notify the Fund Office as soon as you are called up for qualified military service and set forth the option you have elected to exercise. Your right to maintain and reinstate coverage by reason of qualified military service will be administered and interpreted by the Plan in accordance with the requirements of the USERRA. The contributions, if any, credited to you will be kept on the Plan’s records during the qualified military service leave of absence, and your coverage and coverage for your Spouse and your Eligible Dependent Children will be reinstated, provided you return to work in Covered Employment or seek re - employment with an employer within the time period protected und er the USERRA. If you are honorably discharged from the Uniformed Services, Plan coverage for you, your Spouse, and Eligible Dependent Child will be reinstated on the day you begin work with an Employer participating in the Plan, provided that you comply w ith the notice on return to work requirements of USERRA. These requirements and additional information on USERRA can be found at the Department of Labor website at: http://www.dol.gov/ve ts/programs/userra/userra_fs.htm . Extension of Coverage under COBRA Continuation Coverage (COBRA) The right to COBRA Continuation Coverage was created by a federal law, the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA). COBRA Continuation Coverage can become available to you when you otherwise lose your group health coverage. It also can become available to your Spouse and Eligible Dependent Child who are covered under the Plan at the time they would otherwise lose their coverage. This con tinuation of coverage under the Plan is a temporary extension of coverage, with a period of coverage that is determined by the type of event (qualifying event) that would otherwise trigger your loss of coverage (or loss of coverage for your Spouse and/or E ligible Dependent Child). This continuation of coverage is provided in addition to the Plan P rovided Continuation of Coverage Benefit noted on the next page . To be enrolled in the Plan under COBRA Continuation Coverage, you, your Spouse or Eligible Depende nt Child must elect to continue coverage, complete the election form, and submit the completed form to the Fund Office within the applicable time period. In addition, the monthly premiums must be paid on a timely basis and sent directly to the Fund Office. See Section on COBRA Continuation Coverage below for more details on this benefit.

16 Continuation Coverage (Self - Pay) Plan Provided Co ntinuation of Coverage Benefit If an active employee loses eligibility because of the termination or reduction in hours o f employment, eligibility to participate in health care coverage may be continued by making self - payments, payable to the Fund, for a period of up to six (6) months. This benefit is available to eligible Participants in addition to COBRA continuation cover age , except where such addition would result in more than 36 - month s of total continuation coverage . Note: Upon termination or reduction is hours, the employee will have until the later of: (a) 60 days from the date of notification of the option to elect th is benefit, or (b) 60 days from the date eligibility is lost, to notify the Fund Office of his or her election to continue eligi bility by making self - payments. COBR A Continuation Coverage Benefit COBRA Continuation Coverage is a continuation of your health care coverage under the Plan when coverage for you, your Spouse, Eligible Dependent Children, would otherwise end because of a life event known as a “qualifying event.” Specific qualifying events are listed below. After a qualifying event, COBRA Continuation Coverage must be offered to each person who is a “qualified beneficiary.” you, your Spouse, and your Eligible Dependent Children could become Qualified Beneficiaries if coverage under the Pla n is lost because of the qualifying event, and you, your Spouse, or Eligible Dependent Children were enrolled in coverage under the Plan at the time the Qualifying Event occurred. Qualified Beneficiaries who elect COBRA Continuation Coverage must make mont hly self - payments for coverage, on or be fore the due date. You, as the participant/employee will become a “Qualified Beneficiary” if you lose your coverage under the Plan because any of the fol lowing Qualifying Events occur: • A reduction in your work hours which causes a loss of eligibility under the Plan; or • Your employment ends for any reason other than your gross misconduct; • You lose retiree coverage due to becoming entitled to Medicare (Part A, Part B, or both if the retiree terminates retiree coverage after electing Medicare. Your Spouse will become a “Qualified Beneficiary” if coverage under the Plan is lost because any of the following Qualifying Events: • Your death; • You experience a reduction in work hours, which causes a loss of eligibility under the Plan; • Your employment ends for any reason other than your gross misconduct; • You lose retiree coverage due to becoming entitled to Medicare (Part A, Part B, or both); or • You become divorced or legally separated from your Spouse. Your Eligible Dependents wi ll become qualified beneficiaries if they lose coverage under the Plan because of any of the following qualifying events: • Your death; • You experience a reduction in work hours, which causes a loss of eligibility under this Plan; • Your employment ends for any reason other than your gross misconduct; • You lose retiree coverage due becoming entitled to Medicare benefits (Part A, Part B, or both);

17 • You and your Spouse become divorced or legally separated; or • Your dependent child no longer meets the eligibility requ irements under the Plan. For example, the dependent child reaches age 26 and no longer meets the eligibility definition as of the end of the month of his or her 26th birthday. Who Is a Qualified Beneficiary? A “Qualified Beneficiary” under COBRA is any par ticipant or eligible dependent who, on the day before the Qualifying Event, has coverage under the Plan, who would otherwise lose such coverage due to the Qualifying Event, and timely elects to receive COBRA Continuation Coverage. The term Qualified Benefi ciary includes any eligible dependent who is born to, or placed for adoption with, you during the period of COBRA Continuation Coverage. Adding a dependent to your coverage may cause an increase in your COBRA premiums. If a Qualified Beneficiary with COBRA Continuation Coverage acquires an eligible dependent, the eligible dependent may be added to the coverage for the remainder of the COBRA Continuation coverage period. If a Qualified Beneficiary has a dependent who was eligible, but not enrolled in the Pla n at the time the Qualified Beneficiary enrolled for COBRA continuation coverage because the dependent had other group health coverage at that time, and the dependent loses the coverage under the other group health plan due to exhaustion of COBRA continuat ion coverage, you may add the dependent to your coverage for the remainder of the COBRA continuation coverage period. The addition must be completed within 30 calendar days after the dependent’ s loss of the other coverage. Who Must Give Notice of the Qual ifying Event? Employer’s Responsibility The Plan will offer COBRA continuation coverage to qualified beneficiaries only after the Fund Office has determined, or been notified, that a Qualifying Event has occurred. Your contributing employer must notify the Fund Office if: • You experience a reduction in work hours that causes a loss of eligibility under the Plan; • Your employment ends for any reason other than your gross misconduct; • You die; or • You become entitled to Medicare benefits (Part A, Part B or both). Your Responsibility You are responsible for providing the Fund Office with timely notice of the following Qualifying Events: • You and your Spouse are divorced or are legally separated; • An eligible dependent has ceased to meet the eligibility requirements; • If there is an occurrence of a “second qualifying event” experienced by you or any other qualified beneficiary after you, or the other qualified beneficiary who previously became entitled to COBRA with a maximum duration of 24 (or 35) calendar months. This second qualifying event could include your death, you become entitled to Medicare, your divorce or legal separation, or your dependent losing eligibility status under the Plan. (More information about second qualifying events is provided later in this sec tion.); • If a qualified beneficiary entitled to receive COBRA continuation coverage with a maximum of 24 calendar months has been determined by the Social Security Administration to be disabled. If this determination is made at any time that an individual i s disabled during the first 60 calendar days of COBRA continuation coverage, the qualified beneficiary may be eligible for an 11 - calendar month

18 extension of the original 24 - calendar month maximum coverage period, for a total of 35 calendar months of COBRA continuation coverage; and • If the Social Security Administration determines that a qualified beneficiary is no longer disabled. Failure to provide the proper notice within the required timeframes, as set forth below, may prevent you from obtaining or exte nding COBRA continuation coverage. The Fund Office will determine whether a qualifying event has occurred for purposed of COBRA Continuation Coverage. However, you should promptly notify the Fund Office of any of these qualifying events listed herein. This will allow the Fund Office to process your election for continuation of coverage more efficiently, with little or no interruption your coverage and the handling of your claims. Procedures for Notifying the Plan of a Qualifying Event To notify the Fund Off ice of any of the qualifying events listed above, a “qualified beneficiary” can send a notice via U.S. First Class mail, fax or email to request continued coverage under the Plan within the later of 60 calendar days from the date of the qualifying event or the date coverage was lost under the Plan due to the qualifying event. The notice must be in a form that documents the date sent ( e.g ., if sending by mail, the request must be postmarked no later than 60 calendar days after the date described above). In t he event of divorce or legal separation, you must also submit a copy of the divorce decree or written proof of the legal separation. In the event of a Social Security Administration determination of disability, you must submit a copy of the Social Securit y disability determination. If you are providing notice of a Social Security Administration determination of disability, the notice must be postmarked no later than 60 calendar days after the latest of: • The date of the disability determination by the Socia l Security Administration; • The date on which the qualifying event occurs; or • The date on which the qualified beneficiary loses (or would lose) coverage under the plan as a result of the qualifying event. Notice of a Social Security disability determination must be submitted to the Fund Office before the end of the first 18 calendar months of the COBRA continuation coverage. If you are providing notice of a Social Security Administration determination that a qualified beneficiary is no longer disabled, the notice must be postmarked no later than 30 calendar days after the date of the final determination by the Social Security Administration that the qualified beneficiary is no longer disa bled. Notice may be provided by the participant or qualified beneficiary with respect to the qualifying event, or any representative acting on behalf of the participant or qualified beneficiary. Notice from one individual will satisfy the notice requirement for all related qu alified beneficiaries affected by the same qualifying event. Address to Notify Plan Administrator of Qualifying Event National IAM Benefit Trust Fund 1300 Connecticut Avenue, NW, Suite 300 Washington, DC 20036 Determining the Duration of COBRA Continuation Coverage Once the Fund Office determines or receives notice that a qualifying event has occurred, COBRA continuation coverage will be offered to each of the qualified beneficiaries. Each qualified beneficiary will have an independent right to elect COBRA continuation coverage. Participants may elect COBRA

19 continuation coverage on behalf of their spouses, and parents may elect COBRA continuation coverage on behalf of their children. Generally under COBRA, an E mployee may elect to continue coverage by making timely self - payments for up to 18 months for COBRA qualifying events. However, under this Plan, except where otherwise noted below, coverage may be continued by making timely self - payments for up to 24 month s if the loss of coverage is for any termination of employment or loss of hours in employment covered by the Plan. Consequently, continuation of coverage with respect to termination of employment or loss of hours in employment will be collectively referre d to as continuation of coverage. In the case where the qualifying event is your death, you become entitled to Medicare benefits (under Part A, Part B, or both), you and your Spouse divorce or are legally separated, or your covered dependent is losing elig ibility under the Plan, the length of COBRA continuation coverage may be in effect up to a total of 36 calendar months f or each qualified beneficiary. In the case where the qualifying event is termination of your employment or reduction of your hours of e mployment to result in failure to meet eligibility under the Plan, or you become entitled to Medicare benefits less than 18 calendar months before the loss of coverage due to a qualifying event, the length of COBRA continuation coverage may be for a period of up to 36 calendar months for each qualified beneficiary, except for your coverage, starting after the date you became entitled to Medicare c overage (Part A or B, or both). For example, if you become entitled to Medicare eight months before the date on which your employment terminates or you experience a reduction in your hours of employment that result in loss of eligibility to participate in health coverage under the Plan, the period of COBRA continuation coverage for your Spouse and covered dependents may be elected for a period up to 36 calendar months beginning after the date of your Medicare entitlement, and is equal to 28 calendar months after the date of the qualifying event (36 calend ar months minus eight months). In the case when the qualifying event is the termination of your employment or reduction of your hours of employment to result in failure to meet the eligibility requirements under the Plan, the COBRA continuation coverage period generally will last up to a total of 24 calendar months ( see above). However, this 24 - calendar month period of COBRA continuation coverage may be extended in the fol lowing two instances: • Extension of 24 - calendar Month Period of Continuation Coverage Due to Disability If you, your Spouse or your Eligible Depende nt Child covered under the Plan is determined by the Social Security Administration to be disabled, and you notify the Fund Office in a timely fashion, you and your covered dependents may be entitled to receive up to an additional 11 calendar months of COB RA continuation coverage (for a total maximum of 35 months). The disability must be determined some time before the 60 th day of COBRA continuation coverage, and must last at least until the end of the 24 - calendar month of the original period of continuatio n coverage. • Extension of 24 - calendar month period of continuation coverage Due to a Second Qualifying Event If you, your Spouse or Eligible Dependent Child covered by the COBRA Continuation Coverage experiences another qualifying event (a “second qualifyi ng event”) while covered under an 24 - calendar month Continuation Coverage that includes the six - month continuation coverage period provided under the Plan plus the eighteen - month period under COBRA (or a 35 - calendar month period of coverage if disabled), y ou and your covered qualified beneficiaries may be eligible for additional months of COBRA Continuation Coverage for a maximum period of COBRA Continuation Coverage of up to 36 calendar months. Timely notice of the second qualifying event must be given to the Fund Office.

20 This extension may be available to any eligible dependents (if they are qualified beneficiaries) receiving continuation coverage if the participant or former participant dies, becomes entitled to Medicare benefits (under Part A, Part B o r both), or gets divorced or legally separated, or if the dependent child stops being eligible under the Plan as an eligible dependent child. In no event will any Spouse, or Eligible Dependent Child be eligible for more than 36 total months of continuation coverage. This extended period of continuation coverage is not available to anyone who became your Spouse after the termination of employment or reduction in hours. However, this extended period of continuation coverage is available to any child born to, adopted by, or placed for adoption with you (the active Employee) during the 24 - month period of cont inuation coverage. In no case are you entitled to Continuation Coverage for more than a total of 24 months if your employment is terminated or you have a r eduction in hours (unless you are entitled to an additional continuation coverage period on account of disability). Therefore, if you experience a reduction in hours followed by termination of employment, the termination of employment is not treated as a s econd qualifying event and continuation coverage may not be extended beyond 24 months from the initial, qualifying event. COBRA Continuation Coverage and Disability If you are a covered Employee and you lose coverage due to termination of employment as th e result of your disability, you may elect to enroll in COBRA Continuation coverage. As in the case of all COBRA Continuation Coverage, you must self - pay for the premiums during the coverage period. Your coverage will continue until the earliest of: • The da te you cease to be disabled or return to active work; • The date you attain age 65; or • The expiration of the applicable COBRA Continuation Coverage period. Summary of Periods of Continuation Coverage Qualifying Event Resulting i n Loss of Coverage Qualified Beneficiary Maximum Continuation Coverage Period 1.

Disability as certified by Social Security Administration of any COBRA covered qualified beneficiary Participant, Spouse or Dependent Child with the disability 35 months after the date of the qualifying event 1 or longer in certain circumstances 2 7. Termination of employment due to retirement Employee, Spouse and Dependent Children 24 months after t he date of the qualifying event 1 or longer in certain circumstances 3 Benefi ts While on COBRA Continuation Coverage If you choose to elect COBRA Continuation Coverage, the Plan will provide an extension of your health care coverage that was in effect the day before the qualifying event occurred and that is identical to similarly situated participants under the Plan. Note: Benefits under life and accidental death and dismemberment insurance and short - term disability are not subject to COBRA. Therefore, these benefits are not continued under the terms and conditions of the Plan, al though there may be conversion options under the applicable life insurance policy. Following receipt of a notice or after a participant’s loss of eligibility due to a termination of employment or reduction in hours of employment, the Plan will notify the participant, Spouse and their Eligible Dependent Child of their rights to purchase COBRA Continuation Coverage and the cost of such coverage that you will self - pay . Making the Election for COBRA Continuation Coverage When the Fund Office receives informati on concerning the loss of health care coverage due to a qualifying event, the participant or eligible family member will be sent a notice explaining their right to elect COBRA Continuation Coverage. The notice provides you (or eligible family member) with information regarding your coverage options and the cost to you associated with each option. The Notice also will include an election form you must complete and return to the Fund Office within the applicable time in order to activate your coverage under C OBRA. The completed election form must be submitted to the Fund Office, within 60 days after the later of; (1) the date coverage would otherwise end, or (2) the date the qualified beneficiary receives the notice of the right to elect Continuation Coverage. Each qualified beneficiary who elects Continuation Coverage must be named on the election form, or a separate election form must be submitted for any person not named on the form. If, for any reason, the Fund Office does not receive a completed election f orm within the 60 - day period for any particular qualified beneficiary, the eligibility period for that qualified beneficiary to elect COBRA Continuation Coverage will expire and his or her health benefits will terminate as of the date on which he or she fi rst became a qualified beneficiary (i.e., when coverage under the Plan terminated) . Neither the Fund Office nor the Plan will be responsible if a parent or guardian, acting on behalf of a minor qualified beneficiary, does not inform the minor qualified be neficiary of his or her right to elect COBRA Continuation Cov erage within the 60 - day period. 1 This 24 - month maximum period includes th e 18 - month statutory COBRA period plus an additional 6 months self - pay, as provided under the Plan. 2 Refer to above section concerning COBRA Continuation Coverage and Disability 3 The length of the COBRA Continuation Coverage will depend on whether the participant applies for Medicare before or after beginning COBRA Continuation Coverage.

22 Cost of COBRA Continuation Coverage The cost of coverage under COBRA is paid totally by you or the other qualified beneficiary covered under the Plan. The monthly rates you will self - pay reflect the cost of medical benefits under the Plan, plus a 2% administration fee as allowed under COBRA. In the event that your coverage is based on a Social Security Administration or Railroad Retirement Board disability award, yo ur monthly premium may include a surcharge. Also, the rate for COBRA coverage may change due to changes in the benefits offered by the Plan and, in certain circumstances, to reflect changes in the cost of the Plan’s benefits. Absent these restrictions or c onditions, your COBRA rate generally will remain in effect for a period of 12 - months. Under the law, you are required to pay the full cost for this coverage. More details are included in the individual COBRA election notice you will receive. The initial pa yment must be received by the Plan within 45 days after the date of your election for COBRA Continuation Coverage. The initial premium must be paid to cover the period of coverage from the date of the election, retroactive to the date of the loss of covera ge due to the Qualifying Event. Subsequent premiums amounts will be due on the first day of each calendar month for the duration of the applicable period of coverage. It is the responsibility of each qualified beneficiary or person acting on behalf of a qu alified beneficiary, to ensure that the Fund Office receives the correct payment on a timely basis. Nether the Plan or the Fund Office is responsible if the qualified beneficiary causes himself or herself to lose the Continuation Coverage through a failure to submit the corre ct payment in a timely fashion. Termination of COBRA Continuation Coverage Continuation Coverage will terminate as noted above, or the earliest of: • The date of death for the covered individual; • The last day of the applicable maximum c ontinuation period; • The last day of the month for which you made a timely self - payment for COBRA Continuation Coverage; • The date you (as a Spouse) remarry or marry and obtain coverage under another group health plan; • The date you obtain coverage as an emp loyee under another employer - sponsored group health plan; • The date you become eligible for coverage under Medicare unless other rules apply as noted above; • The date the Social Security Administration or Railroad Retirement Board makes a determination that you are no longer disabled; • The date the Plan terminates; or • The date your employer ceases to be a Contributing Employer, except as noted below. If your Employer stops participating in the National IAM Benefit Trust Fund, the Fund will continue to carry t he COBRA Continuation Coverage benefits for you, your Spouse, and your Eligible Dependent Children only if the Employer does not substitute another plan. If the Employer establishes one or more group health plans, or starts contributing to another multi - em ployer group health plan, the plan established by the Employer or the other multi - employer plan must make COBRA Continuation Coverage available to you, your Spouse and/or your Eligible Dependent Child, who: • Was receiving coverage under the Plan (including Retiree coverage) immediately before the Employer’s cessation of participation; and • Is, or whose qualifying event occurred in connection with, a covered Employee or Retiree whose last coverage before the qualifying event was through the applicable Employer .

23 If you are a self - pay retiree that becomes “orphaned” because your former Employer stops participating in the National IAM Benefit Trust Fund due to the loss of a service contract, you will not lose your eligibility to continue self - payment for coverage provid ed : • The bargaining unit work continues under a successor contractor; • The successor contractor remains or becomes a contributing Employer to the Fund, and • The successor contractor continues to make the required contributions to the Fund for coverage of active bargaining unit employees. Note: Orphaned retirees will lose eligibility for self - pay coverage when there is no successor service contractor or when they experience other termination events. Application of Continuation Coverage to Retirees Some contributing Employers of the National IAM Benefit Trust Fund provide Retiree coverage for qualified Retirees and their dependents. Refer to the applicable collective bargaining agreement or other participation agreement for information on whether such cov erage may be available, and for specific rules about how long such coverage is provided. Other contributing employers have no specific Retiree coverage. If there is a loss of coverage in either case, the Plan offers continuation coverage on a self - pay basi s. If you are a covered Employee and you lose coverage due to your termination of employment at retirement, or if you are a covered Retiree and you lose Retiree coverage for any reason, you may elect continuation coverage by making timely self - payments unt il the earliest of: • The date you return to active work; • The date you attain age 65 or become eligible for Medicare coverage; or • The occurrence of other applicable termination event s described in the Termination of COBRA Continuation Coverage section of th is Summ a ry Plan Description. If you are a retired Employee and should lose Retiree coverage due to the bankruptcy of your last contributing Employer, you have the right to choose continuation of health coverage for an indefinite period of time, but not bey ond the occurrence of other applicable termination events described in the COBRA Continuation Coverage section . Continuation Coverage or Extension of Coverage Other Than COBRA Some contributing Employers of the National IAM Benefit Trust Fund provide a tem porary extension of healthcare coverage if the Employee is terminated or is totally disabled or hospitalized, and/or the Employer terminates participation in the Fund. Refer to your applicable p articipation a greement for information on whether such an exte nsion may be available to you. The policy of the Trustees is that any such extension of coverage will be made available to you first, followed by COBRA Continuation Coverage so that you, your Spouse, and/or your Eligible Dependent Children will receive the maximum uninterrupted coverage period that can be provided under the Plan and the terms of your employment.

24 Comprehensive Medical Coverage The Plan will pay medical benefits as set forth in this SPD for covered medical charges incurred by you, your Spouse , or your Eligible Dependent Children while eligible for medical benefits under the Plan. Medical Benefit A Medical Benefit is the amount, if any, the Plan will pay for covered medical charges incurred by you, your Spouse, or your Eligible Dependent Child. The amount of a medical benefit is the amount the Claims Administrator calculates in the steps shown below: • The charges f or which a claim is submitted to the Claims Administrator are tested against the covered medical charge definition. The submitted charges that meet all of the tests are the covered medical charges under the Plan. • Any copayment amount that applies to the ch arges is subtracted from the amount of covered medical charge s. • If any part of the remaining amount exceeds an applicable benefit maximum, then that part is subtracted and the remainder is the amount of the medical benefit. Medically Necessary Charges Pla n benefits are payable for charges incurred only to the extent the charges are for services, supplies and treatments that are medically necessary as defined under the terms of the Plan, and only up to the applicable maximum allowed for such benefits, servi ces, or supplies under the terms of the Plan. Certain services are not subject to the medically necessary definition, as noted in the SPD . Deductible The deductible shown in the Schedule of Benefits: • Applies to all covered medical charges unless otherwise stated; • Applies separately to each participant during each calendar year; and • Must be accumulated during the applicable calendar year. No charge will be subject to more than one deductible amount. Only those charges to which a deductible applies will be a pplied to satisfy the applicable deductible. When a covered individual’s cumulative deductible in a calendar year reaches the individual deductible maximum amount as shown in the Schedule of Benefits, the deductible will be considered met in full, and no further deductible amounts will be applied to any charges incurred by the applicable participating individual in the applicable calendar year. Family Deductible Maximum When eligible covered individuals in your family have accumulated their individual ded uctible amounts in any calendar year that, when combined, reach the family deductible maximum amount as shown in the Schedule of Benefits, the family deductible will be considered met in full, and no further deductible amounts will be applied to any charge s incurred in the applicable calendar year by any of the applicable covered individuals in your family. The result of this rule is that some covered individuals in your family may fully satisfy their individual deductible amount before receiving benefits under the Plan (except for Preventive Services with no applicable deductible amount and no cost sharing), while other covered individuals may end up having to satisfy only a portion of their applicable individual deductible amount because collectively betw een those members the entire family deductible amount is met in full.

25 For this purpose, family includes you and all eligible members of your family, including your Spouse and Eligible Dependent Child t hat are covered under the Plan. Deductible Carry - Over I f a covered individual incurs charges during the last three months of a calendar year that are applied toward satisfaction of the deductible, those charges will also be applied toward the individual’s deductible for the next calendar year. Copayment A Cop ayment is the amount a participant must pay to his or her provider of service before benefits are payable by the Plan. The copayment shown in the Schedule of Benefits: • Applies to all covered medical charges unless otherwise stated; • Applies separately to e ach participant ; and • Applies separately for each visit, stay, procedure or item unless otherwise stated No charge will be subject to more than one copayment amount. Coinsurance The coinsurance shown in the Schedule of Benefits i s the patient percentage o f Covered Medical Charges for which you are responsible after the Plan’s payment (e.g. if the Plan pays 90% of a covered service, your coinsurance is the remaining 10%). Your coinsurance: • Is generally payable when your provider bills you after submitting your claim to the Plan; • Does not include expenses not covered by the Plan ; and • Does not include your deductible or copayments (although these are included in your out - of - pocket limit explained later). Common Accident If you, your Spouse, and any of your E ligible Dependent Child incur covered medical charges as a result of injuries suffered in a common accident, only one deductible will be applied during each calendar year to those charges. If greater medical benefits would be paid in the absence of this pr ovision, then this provision will not apply. Payment Percentage The Payment Percentage and the covered medical charges to which such Payment Percentage applies are shown in the detailed Schedule of Benefits. The Payment Percentage applies after any applic able copayment amount has been met, and it is applied separately to each covered individual. Out - of - Pocket Limit The individual and family out - of - pocket limits are shown in the Schedule of Benefits. A separate out - of - pocket limit for the Prescription Drug Coverage applies for benefits under the Plan. The out - of - pocket limit is the maximum amount a covered individual will have to pay for covered charges during a calendar year. The out - of - pocket limit includes the deductible , copayments and coinsurance . When a covered individual’s cumulative out - of - pocket expenses in any calendar year reaches the applicable out - of - pocket limit shown in the Schedule of Benefits, all covered charges for the covered individual will be paid by the Plan at 100% for the remaini ng months of that calendar year. When your covered family members have accumulated individual out - of - pocket amounts in any calendar year that, when combined, equals or exceeds the amount of the family out - of - pocket limit

26 shown in the Schedule of Benefits, all further covered charges for all covered family members will be paid by the Plan at 100% for the remaining months of that calendar year. For this purpose, the term family includes you, your Spouse, and your Eligible Dependent Children who are covered under the Plan. The above provisions do not apply to charges that exceed Usual, Customary and Reasonable (UCR) charges, charges that exceed Plan benefit limitations, or charges for services that are excluded under the terms of the Plan. Accumulation of Ded uctible and Out - of - Pocket Limits Covered expenses incurred either in - network or out - of - network will cross accumulate to satisfy deductible amounts and maximum out - of - pocket limits. However, note that separate out - of - pocket limits apply to in - network and ou t - of - network covered medical charges and Prescription Drug Coverage. Lifetime Maximum The Plan does not impose an overall lifetime dollar maximum. However, there are limits that may apply for some types of visits, and/or a limit on the number of days perm itted for the benefit under the terms of the Plan. In addition, there may be dollar limits applicable to certain benefits as described in this SPD.

27 Preferred Provider Organization The Plan contracts with Cigna Healthcare (Cigna) for access to a nationwide preferred provider network (PPO). If you utilize services provided by physicians, other health care professionals, hospitals, or other health care facilities in the Cigna Open Access Plus PPO Network (OAP) this will result in less cost to you and the Plan . When you select a Cigna participating provider for your medical services, you will have, in general, a higher percentage benefit payment and a lower out - of - pocket cost than if you select to receive those services from a non - participating provider. Cigna participating providers have agreed, by contract, to accept payments from the Plan for services and benefits at discounted levels negotiated by Cigna. When you are seeking services from a provider, please present your medical ID card at each visit. The ca rd identifies you as a Cigna Open Access Plus (OAP) network participant, and gives the participating provider necessary billing information for purposes of submitting your claims. Note: you are not required to use an OAP provider. It is your choice. Howev er, both you and the Plan will experience savings if you choose to utilize an Open Access Plus in - network provider for your medical needs. Participating providers in the Cigna OAP Network include physicians, hospitals, other health care professionals, and other health care facilities. To find participating providers in the Cigna OAP network, please access the Plan’s website at www.iambtf.org , or register on Cigna’s website at www .mycigna.com . You also may get OAP provider information by calling the toll - free number shown on the back of your identification card, 800 - 244 - 6224 or 800 - Cigna 24. We recommend that you confirm a provider’s current participation in the OAP network by calling Cigna directly before treatment. If you would like a paper directory of providers, please contact Cigna at the number on your medical identification card to request a copy for your zip code area. If you need ass istance, please contact the Fund Office at 202 - 785 - 8148 or 800 - 457 - 3481. Applicability of In - Network Benefits You must utilize a Cigna Open Access Plus network provider to obtain in - network benefits with the accompanying financial advantages. The followi ng are exceptions to this rule: Emergency Medical Care Whenever possible, you should request treatment from Open Access Plus providers. However, benefits will be provided at the in - network level for all medically necessary Emergency Services associated with true medical Emergencies that are received in the Emergency Room of both in - network and out - of - network hospitals. If You’re Not Able to Access an In - Network Provider Except where benefits are specifically limited to in - network providers, if there are no C igna Open Access Plus providers within a 25 - mile radius of your home, benefits will be provided at the in - network level for any covered provider that is located within the 25 - mile radius of your home, regardless of network participation of the provider. Ou tside the 25 - mile radius surrounding your home, the normal in - network and out - of - network benefits will apply b ased on the provider’s network status. You may want to inquire of the provider’s status before obtaining services outside the 25 - mile radius becau se services obtained from an out - of - network provider will be subject to out - of - network benefits. Hospital Assigned Services Whenever possible, you should advise your hospital and your attending physician or Allied Health Professional of your need to use Open Access Plus providers for all referral services. However, if you receive services from a Cigna Open Access Plus participa ting hospital, and the hospital makes a referral

28 to a non - participating provider, benefits for covered services will be provided at the in - network level. This standard will apply when the services you receive are not within your control. For example , when your participating hospital assigns you a non - participating anesthesiologist or Emergency Room Physician, or refers your lab tests or x - rays to a non - participating pathologist or radiologist for interpretation. Opportunity to Select a Primary Care Physicia n Under the terms of the Plan, you are not required to select a Primary Care Physician (PCP), but may do so if you wish. You may use Cigna’s Open Access Plus network to select a Primary Care Physician for yourself, your Spouse, and/or your Eligible Dependent Child. The role of the PCP is to provide or arrange for medical care. Whether you select a PCP or not, you, your Spouse, and/or your Eligible Dependent child may exercise their choice of other health care providers without authorization from the PCP to provide the covered services they need, including Specialists. Each individual covered under the Plan has the right to select a PCP from Cigna’s list, and such PCP may be different for each covered individual. Cigna’s Toll - Free Care Line Cigna’s tol l - free care line allows you to talk to a health professional at any time, seven days a week, 24 hours a day, by calling the toll - free number shown on the back of your identification card at 800 - Cigna 24 (800 - 244 - 6224). The staff at Cigna’s toll - free care l ine can provide you with names of Open Access Plus participating providers. You, your Spouse, and/or your Eligible Dependent Child may call Cigna Health Care toll free number if you need medical care. The staff will assist you with the available options. Access to Cigna Participating Providers While on Travel If you, your Spouse, or your Eligible Dependent Children need medical care while away from home, including travel outside the U.S., you have access to a national network of participating providers th rough Cigna’s Away - From - Home Care feature. You can call Cigna Health Care toll free care line, 800 - Cigna 24, and the staff will provide you with names of Open Access Plus participating providers in other network areas. If you obtain the name of a participa ting provider from Cigna’s website or through the care line, Cigna recommends that you call the provider to confirm that the provider is currently participating in the Open Access Plus network before you make an appointment. If You Have a Complaint about Cigna If you have any type of complaint about Cigna, you may contact Cigna member services. You should contact Cigna member services if you have any concerns regarding a Cigna employee, the quality of care provided by Cigna participating providers, or the processing of your claims (including claims for your covered family members). The toll - free number for Cigna member services is 800 - Cigna 24 (or 800 - 244 - 6224) as shown on the back of your Cigna identification card. You also will be able to find the Cigna n umber on any copy of your Explanation of Benefits (EOB) Cigna provides to you. You also have the option to express your concerns to Cigna in writing. Cigna will make every effort to resolve the concerns you raise on your initial contact. However, Cigna may need more time to address your concerns. In this case, someone will get back to you as soon as possible, but no more than 30 days after your initial contact. The Fund Office also is available to you should you have any complaints about Cigna or any aspe ct of the administration of the Plan. You may contact the Fund Office at 202 - 785 - 8148 or toll free at 800 - 457 - 3481. Contacting Cigna member services or the Fund Office to make a complaint does not replace the requirement that you file a written appeal if you are not satisfied with the results of a decision by Cigna on a claim you have submitted for benefits or services received under the Plan. If you do not agree with Cigna’s decision on any claim, you may contact Cigna member services or the Fund Office a bout your concerns. In addition, you must make a written request as set forth under the section governing appeals and as explained in the section “Claims Filing and Appeal Procedures” included in this SPD .

29 PHS+ Precertification Program The Plan requires th at certain outpatient surgical procedures, diagnostic testing and all non - emergency inpatient hospital admissions be certified in advance. Failure to obtain precertification through Cigna’s PHS+ precertification program can result in your claim being denie d. PHS+ precertification will help you and your dependents get the right care, at the right time, in the right place. With PHS+ and its precertification process, you can: • Get the most appropriate inpatient and outpatient care • Find lower cost services • Avo id unnecessary or non - covered medical treatment or procedures • Improve your health with earlier case management services that help to identify when you might need extra assistance How Precertification Works If you use an in - network provider, you don’t nee d to do anything for precertification. The Open Access Plus network (OAP) contracted provider is responsible for getting the precertification for all required non - emergency in - network services. If you use an out - of - network provider for non - emergency services, you are responsible for necessary precertification. To do this, you will need to call the customer service phone number on the back of your Cigna ID card. A service representative will walk you through the precertification process.

30 What Requires Precertification The PHS+ Precertification Program includes precertification for all non - emergency inpatient admissions, post admission review for emergency admissions, and many outpatient services. A list is provided below that shows representative servi ces requiring precertification.

31 Case Management Case management is a service that assists covered individuals with treatment needs that extend beyond the acute care setting. The goal of case management is to ensure that patients receive appropriate care in the most effective setting possible; whether at home , as an outpatient, or as an Inpatient in a hospital. If there is a need for case management, a case management professional will work closely with the patient, the family members, and the attending physician to determine appropriate treatment options that would best meet the patient’s needs, while maintaining manageable costs to the Plan. Case managers will help coordinate the treatment program and arrange for the necessary resources. In addition, case managers will answer questions and provide ongoing sup port for the family members during a medical crisis. While case managers, who are trained Registered Nurses and other credentialed health care professionals, may recommend alternate treatment programs and coordinate resources, your attending physician rema ins in charge of, and responsible for, your actual medical care. Participation in case management program is recommended for patients who need post - hospitalization services, or who have difficulty in managing or dealing with a costly illness. Cigna, may on occasion, contact you or your attending physician if they believe that case management might be helpful in your case. However, it is important to remember that participation in the case management program is voluntary. You should discuss the option of the case management with your attending physician, and contact Cigna for more information. You, your Spouse, your Eligible Dependent Child, and/or your attending physician may request case management services by calling Cigna at the toll - free number on your i dentification card, 800 - 244 - 6224 or 800 - Cigna 24.

57 Prescription Drug Coverage — CVS Caremark The Plan will pay fo r certain drugs that are prescribed by your physician or Allied Health Professional, after you pay the applicable copayment or coinsurance . If you, your Spouse, or Eligible Dependent Child get a covered prescription filled or refilled at a participating ph armacy that has an agreement with the pharmacy benefit manager ( CVS Caremark ), the Plan pays the total cost of the prescription minus your copayment or coinsurance . You will be supplied with a CVS Caremark Prescription Drug Card, which you must present at the participating pharmacy when you get a prescription filled. The Plan does not cover prescriptions filled or refilled at non - participating pharmacies. CVS Caremark Specialty Pharmacy Services include a program called ACSF, which means Advanced Control Sp ecialty Formulary . With ACSF, in addition to the required medical necessity review, Specialty Medications will also be reviewed to determine whether a preferred alternative exists that should be tried first. If an alternative is available, it will be discussed with your physician or Allied Health Professional and the script changed. This is part of the prior authorization process wh ich will be transparent to you. The prescription copayment or coinsurance shown in the Schedule of Benefits is your out - of - pocket expense for each covered prescription that is filled. Under the terms of the Plan, different copayment or coinsurance levels apply for generic drugs, preferred brand name drugs, and non - preferred brand name drugs. If you use generic drugs whenever possible you will incur the lowest out - of - pocket expense to you and to the Plan. To determine the applicable copayment or coinsurance for any particular drug, you can go to the CVS Caremark website at www.caremark.co m , and register to obtain specific benefit information. Or, you can call the CVS Caremark Customer Care line at 800 - 282 - 8503. Note: Prescription drug copayments or coinsurance are not reimbursable under this benefit or an y other provision of the Plan. The Plan limits the amount of a drug you can get at any one time under the prescription drug benefit. You have the following options to obtain your prescription: • Mail Order will provide up to a 90 - day supply of covered maintenance medication. • CVS Retail P harmacies will provide up to a 90 - day supply of covered maintenance medication. • Other Participating Retail Pharmacies will provide up to a 34 - day supply of any covered medication. • CVS S pecialty will provide up to a 34 - day supply of specialty medication, or other quantity as appropriate based on dosing, therapy, and handling limitations. Out - of - Pocket Limit T he Plan includes an out - of - pocket limit on the prescription drug program administered by CVS Caremark . The out - of - pocket limit is shown in the Schedule of Benefits. When a participant’s cumulative out - of - pocket expenses in a calendar year reach the applicable out - of - pocket limit shown in the Schedule of Benefits, prescription drug copayments o r coinsurance will be waived for that participant for the rest of the applicable calendar year. When covered participants in your family have accumulated individual out - of - pocket amounts in the applicable calendar year that, when combined, equals or excee ds the family out - of - pocket limit shown in the Schedule of Benefits, copayments or coinsurance for prescription drugs will be waived for all covered participants in your family for the remaining months of the applicable calendar year.

58 Covered Charges (F ormulary) Covered charges include only the reasonable and customary charges for drugs and medications, which, in accordance with federal or state laws, may not be dispensed without the written prescription issued by a physician or an Allied Health Profess ional. The CVS Caremark covered drug list (formulary) includes coverage for most prescription drugs; however, some products are excluded from the formulary in favor of therapeutic equivalents. A therapeutic equivalent is a drug that has essentially the sam e effect in the treatment of a disease or condition as one or more other drugs; or more simply, a drug that controls a symptom or condition in the exact same way as another. CVS Caremark may make changes to the formulary from time to time. To determine wh ether a particular drug is covered, you can go to the CVS Caremark website at www.caremark.com , and register to obtain specific benefit information. Also, you can call the CVS Caremark Customer Care line at 800 - 282 - 8503.

Your physician or Allied Health Professional can call CVS Caremark toll - free at 855 - 240 - 0536 to initiate such a review.

Generic Step Therapy The Plan includes a generic step therapy program that requires participants to try one or more generic equivalent alternatives in most drug class es before the Plan will provide coverage for a brand name medication. If a brand name medication is required, it must be specifically ordered, and the physician or Allied Health Professional will be required to verify that the drug is medically necessary u sing the CVS Caremark prior authorization process. If you have not tried a generic alternative, and do not have prior authorization approval of medical necessity, you will be responsible for full payment of the brand name medication even if the prescriptio n is marked “ dispense as written ” . To avoid any confusion at the pharmacy, we suggest that you inform your physician or Allied Health Professional about the Generic Step Therapy program, and ask them to call CVS Caremark at 800 - 294 - 5979 before accepting a prescription for a brand name drug. CVS Caremark will inform your provider regarding whether the Plan covers the brand name drug, what alternatives are available, and will initiate the medical necessity review process where appropriate. If you have not tr ied a generic or generic equivalent to the brand name drug, your physician or Allied Health Professional will be offered generic alternative options, and will be required to select one. Your brand name prescription will be changed to the generic alternativ e chosen by your physician or Allied Health Professional. Exceptions to Generic Alternatives Your physician or Allied Health Professional can provide CVS Caremark with historic information about alternatives you have tried, if applicable, and request app roval for coverage of a brand name drug. Your physician or Allied Health Professional should provide a statement of medical necessity that explains the clinical reasons why the brand name drug is required. The brand name drug will be allowed if CVS Caremar k confirms medical necessity. Your provider also can call CVS Caremark directly at 800 - 294 - 5979 to request prior approval for coverage of a brand name drug, or to start the authorization process.

62 Medicare Part D The Medicar e Prescription Drug , Improvement , and Modernization Act of 2003 (MMA) added a new prescription benefit for individuals that are eligible for Medicare coverage called Medicare Part D. The Trustees have determined, with the assistance of an actuary, that the Plan’s prescription drug coverage for Medicare eligible participants is actuarially equivalent to Medicare Part D. This means, on average, the Fund’s benefits are equal to or better than the standard Medicare Part D drug plan, and therefore the Fund offer s Creditable Coverage. As required by MMA, each plan participant who is Medicare eligible will periodically receive a notice, called a Notice of Creditable Coverage, advising the individual whether the Plan’s prescription drug benefit continues to be actua rially equivalent to Medicare Part D. An eligible participant also may receive a Notice of Creditable Coverage u pon request to the Fund Office. Medicare eligible participants, active or retired, are not required to sign up for Medicare Part D and may still obtain their prescription benefits coverage through the Plan. If you do enroll in Medicare Part D, your coverage and the coverage for your Spouse and your Eligible Dependent Child under the Plan will be terminated. In such a case, there is no adjustment t o the cost of the coverage under the Plan. If you choose not to enroll in Medicare Part D, your prescription drug coverage under the Plan will continue for you, your Spouse, and your Eligible Dependent Child.

63 Coordination of Benefits The benefits provided by this Plan are coordinated with any benefits payable to you, your Spouse, or your Eligible Dependent Child for the same expenses paid from other group health plans or insurance plans. Coordination means that benefits from the Plan described in this SPD and from other benefit plans and insurance plans cannot exceed 100% of the allowable expense for each covered individual in each calendar year. Coordination is intended to permit up to the full payment of actual allowable expenses without duplication of be nefits. Please Note : There is no Coordination of Benefits under the Prescription Drug Coverage, and prescription drug copayments or coinsurance are not reimbursable u nder the medical Plan benefits. There are several circumstances that may result if you, your Spouse, and/or your Eligible Dependent Child are reimbursed for your medical expenses from this Plan and from another source. If any of the possible sources of payment for health benefits, as lis ted below, apply in the case of you, your Spouse, or Eligible Dependent Child, you must let this Plan know about all such plans under which you have cover age. The application of the COB provisions can occur if you, your Spouse, and/or an Eligible Dependent Child also is covered by: • Medicare or some other government program; • Another group health care plan; • Motor vehicle no - fault coverage for medical expenses; • Workers’ Compensation; or. • If a spouse is employed and covered by a High Deductible Health Plan ( HDHP) with a Health Savings Account (HSA), that spouse cannot be covered by another group health plan. Effect of Coordination Benefits When a covered individual is entitled to medical benefits or services under more than one plan, the rules shown in the o rder as set forth below will be used to decide which plan is the Primary plan . If the Plan described herein: 1. Is the Primary Plan among all plans that cover the participant, then its benefits will be determined without taking into account the benefits or se rvices of any other plan. 2. Is not the Primary Plan , then its benefits may be reduced. The benefits will be reduced so that the benefits provided by all plans will not be more than 100% of the allowable expenses incurred by the applicable participant. The be nefits provided under a Plan include the benefits that would have been provided if a claim had been duly made. The benefits from this Plan will never be greater than those that would be paid in the absence of other coverage. How Much the Plan Pays When it is Secondary When the Plan described in this SPD pays second, it will pay the same benefits that it would have paid had it paid first, less whatever payments were made by the plan (or plans) that was required to pay first. In addition, when this Plan pays second, it will never pay more in benefits than it would have paid had it paid the claim as the primary plan. Deductibles, coinsurance, and exclusions of this Plan still apply. As a result, when this Plan pays second, you may not receive 100% of the total cost of the covered health care services.

64 Plan. The term plan for Coordination of Benefits purposes means a plan that provides benefits or services for medical care by or through any: • Group health plan, including group insurance and a self - insured group he alth plan; • Group practice or prepayment coverage; • Group service plan; • Method of coverage for persons in a group other than as shown in items 1, 2, and 3; or • Coverage that is required or provided by law . The term plan shall also include no - fault motor vehic le insur ance. Understanding Coordination of Benefits Primary Plan. If a plan is considered primary, that plan is responsible for paying first, in accordance with its benefits schedule, all claims for a covered person. Secondary Plan. If a plan is consider ed secondary, that plan is responsible for paying benefits, if any remain, after the primary plan has paid its share. Pre - Paid Plans. Pre - Paid plans (HMOs, EPOs, etc.) that require use of specific providers and pay benefits to only those providers will always be primary for dependents whose coverage by the Pre - Paid plan is because they are, or were, an employee. In such cases, this Plan will reimburse only copayments or expenses that remain on covered charges after the P re - Paid plan has paid benefits. Allowable Expense. Allowable Expense means any necessary, reasonable, and customary item or expense, at least a part of which is a covered expense under any of the plans that cover the person for whom the claim is made. When the benefits from a plan are in the form of services, not payments, the service is considered to be both an Allowa ble Expense and a benefit paid. Claim Determination Per iod. Claim Determination Period means a calendar year. Coordination of Benefits with Medicare and Other Government Programs Medicare. Generally, anyone age 65 or older is entitled to Medicare coverage. Anyone under age 65 who is entitled to Social Securit y Disability Income Benefits is also entitled to Medicare coverage after a waiting period. Medicare has two parts: Hospital Insurance (Part A) and Medical Insurance (Part B). Part A covers inpatient Hospital care and generally is available to all individu als over age 65 at no cost. Part B covers doctor’s services, outpatient Hospital services and other medical supplies and is optional. You must pay a monthly premium for Medicare Part B. Although you are eligible for Medicare Part A once you reach age 65, i f you are an active participant, Part A coverage under Medicare is not automatic unless you have applied for Social Security benefits. Since Part A coverage is not automatic, you and your Spouse can register with Social Security for Part A when you reach a ge 65. You do not have to apply for Social Security payments (that is, actually retire), but you must apply and establish your entitlement to such benefits in order to be covered by Medicare. If you, your Spouse, or your Eligible Dependent Child are covere d by the Plan and by Medicare, and you remain actively employed, your employer - sponsored group health plan will continue to provide the same benefits and the Plan will pay first (Primary) and Medicare will pay second (Secondary). If you are not actively em ployed, Medicare will be the Primary plan for any individual that is eligible for Medicare . Where Medicare is the Primary Plan, its benefits will be taken into account in determining any benefits to be paid under this Plan. The benefits of Medicare Parts A and B will be taken into account

65 whether or not the participant has enrolled. This means that the benefits of Medicare Parts A and B will be estimated and benefits under this Plan will be reduced to the extent that benefits would have been paid had you en rolled in Medicare. In addition, if Medicare is the primary plan, and you elect to use a provider who does not participate in Medicare, the benefits of Medicare Parts A and B will be estimated and the benefits under this Plan will be reduced to the extent that benefits would have been paid had your provider been a Medicare participating provider. The Plan’s benefit payment will coordinate with Medicare’s payment. For covered expenses, the Plan will figure its benefit based on the total expense and then su btract the Medicare benefit and consider the balance as payable under the provisions of this Plan. For these expenses, the Plan carves out Medicare’s payment. However, federal law limits the amount a provider (Hospital, physician, etc.) can charge above th e Medicare payment. The Fund cannot pay the provider more than the amount that Medicare shows as the patient liability for Medicare covered services, and the provider cannot legally bill for more than that amount. When Medicare is primary, claims should be submitted to Medicare first. After Medicare pays the claim, submit a copy of the claim, along with the Medicare explanation of benefits, to Cigna. If you remain actively employed and you or any of your eligible Dependents become entitled to Medicare solel y because of end - stage renal disease (ESRD), this Plan pays first (Primary) and Medicare pays second (Secondary) for 30 months starting the earlier of: • T he month in which Medicare ESRD coverage begins; or • T he first month in which the individual receives a kidney transplant. Then, starting with the 31 st month, Medicare pays first (Primary) and this Plan pays second (Secondary). For the first 30 months, as described above, a ny Covered Medical Charges incurred by such disabled individual should be submitted t o this Plan for payment with any unpaid balance submitted to Medicare. Medicare Advantage Programs If you are a retiree who is covered under a Medicare Advantage program through another employer, your coverage under this Plan will terminate. Medicaid If a covered individual, active or retired, is covered by both the Plan described in the SPD and Medicaid, this Plan pays first (Primary) and Medicaid pays second (Secondary). Military Insurance Coverage The Plan does not cover dependent Spouses who are on act ive duty in any armed forces. However, if any covered individual is covered by both this Plan and Military coverage only, this Plan pays first (Primary) and the Military cove rage pays second (Secondary). Veterans Affairs Facility Services If a covered ind ividual receives services in a U.S. Department of Veterans Affairs hospital or facility on account of a military service - related illness or injury, benefits related to the illness or injury are not payable by the Plan. If a covered individual receives serv ices in a U.S. Department of Veterans Affairs hospital or facility on account of any other condition that is not a military service - related illness or injury, benefits are payable by the Plan to the extent those services are medically necessary and the cha rges are reasonable and customary.

66 Motor Vehicle No - Fault Coverage Required b y Law If you, your Spouse, or your Eligible Dependent Child are involved in a motor vehicle accident and you have, or are required by state law to have, basic reparation coverage, your insurance carrier will be primarily liable for lost wages, medical, surgical, hospital, and related charges. Regardless of whether the Plan described in this SPD is Primary or Secondary, you, your Spouse, or your Eligible Dependent Child (if an adult ) may be required to sign a Reimbursement Agreement and Consent to Lien before any claims relating to the accident will be paid by the Plan. The Reimbursement Agreement permits the Fund to receive reimbursement for expenses paid by the Fund that you recove r through litigation or settlement with another party or insurance company. Rules to Determine Payment Group plans determine which plan pays first by applying Uniform Order of Benefit Determination rules in a specific sequence. This Plan uses the Order of Benefit Determination rules established by the National Association of Insurance Commissioners (NAIC), and which are commonly used by insured and self - insured plans. Any group plan that does not use these rules will be deemed by this Fund to be the Primary plan. Under the rules set forth below, if the first rule does not establish a sequence or order of benefits, the next rule is applied and so on, until an order of benefits is established. The rules are: Rule 1: No Coordination of Benefit Provision If your other plan does not have a Coordination of Benefits provision which coordinates Benefits, th at Plan will always be the Primary Plan. Rule 2: Coverage as a Subscriber and as a Dependent If you are covered under one plan as a subscriber and under the other plan as a dependent, the plan which covers you as a subscriber will be Primary. Rule 3: Dependent Child Covered Under More Than One Plan If you are covered as a dependent under two plans, then the rules are as follows: • The coverage of the parents whose bir thday is first in the year will be primary and the parent whose birthday is later in the year will be secondary. The word birthday refers only to the month and day in a calendar year; not the year in which the person was born. • If both parents have the same birthday, the benefits of the plan in effect longer will be primary; • If the other plan does not have this rule, but instead has a rule based upon the parents’ gender; and if as a result, the plans do not agree on the order of benefits, then the rule in th e other plan will determine the order of pa yment for the claimed benefits. Rule 4: For a Child of Separated or Divorced Parents: • If the terms of a court decree specify which parent is responsible for the health care coverage and expenses of the child, and that parent’s plan has actual knowledge of the Court Order, then that parent’s plan shall be primary. • If no such court decree exists, or if the plan of the parent designated under such a court decree as responsible for the child’s health care coverage and expenses does not have actual knowledge of the court decree, benefits for the child are determined in the following order:  First, the plan of the parent with custody of the child;  Then, the plan of the Spouse of the parent with custody of the child;  Finall y, the plan of the parent not having custody of the child.

67 Rule 5: Coverage of Active Employee and/or Employee’s Dependent: A plan which covers you as an active employee, or that employee’s dependent, is primary. A plan which covers you as a laid - off or re tiree employee, or that employee’s dependent, is secondary. If the other plan does not have this rule and if, as a result, the plans do not agree on which plan is primary, this Rule 5 is ignored. Rule 6: Longer/Shorter Length of Coverage If none of the abo ve rules determines the order of benefits, the plan that covered you longer is primary. The length of time a person is covered under a plan is measured from the date the person was first covered under that plan, and does not start over as the result of a c hange: • In the amount or scope of a plan’s benefits; • In the entity that pays, provides or administers the plan; or • From one type of plan to another (such as from a single employer plan to a Multiemployer plan). Administering Coordination of Benefits To administer COB, the Plan reserves the right to: • Exchange information with other plans involved in paying claims; • Require that you or your health care provider furnish any necessary information; • Reimburse any plan that made payments this Plan should have ma de; or • Recover any overpayment from your hospital, physician, other health care provider, other insurance company, you, your Spouse, or your adult Dependent Child. If this Plan should have paid benefits that were paid by any other plan, this Plan may pay t he party that made the other payments in the amount that the Fund Office, or its designee, determines to be proper under this provision. Any amounts so paid will be considered to be covered benefits under this Plan, and this Plan will be fully discharged f rom any liability it may have to the extent of such payment. To obtain all the benefits available to the covered individual, a claim should be filed under each plan that covers the person for the medical expenses that were incurred. However, any person who claims benefits under this Plan must provide all the information this Plan will need to ap ply COB requirements.

68 Third - Party Liability and Right of Recovery Payment Prior to Determination of Responsibility of a Third Party The Plan does not cover, nor is it liable for, any charges or expenses incurred by a participant, his or her parent(s) and eligible dependent(s) or a representative, guardian or trustee of the participant, parent(s) or eligible dependent(s) (hereinafter, collectively “claimant”) as a res ult of an accident or injury for which one or more third parties (any person or entity) are, or may be, liable. However, subject to the terms and conditions of this Section, the Board of Trustees or their designee, at their discretion, may advance payment for some or all of a claimant’s medical expenses after receipt of a properly executed Reimbursement Agreement and Consent to Lien. In addition, acknowledgement of the Agreement must be provided to the Fund Office Claims Administrator, or designee by the cl aimant’s attorney. The Reimbursement Agreement and Consent to Lien, and Acknowledgement must be executed without alteration or any other condition. Where the Plan has made payments for an injury, irrespective of any signed written agreement, the Plan will have the right to recover from the participant the full amount of benefits paid without deductions or adjustments of any kind if the claimant obtains any settlement, judgment, arbitration or recovery from a third party or from any insurance provider or oth er source. In such event, the Plan will have a first lien on any such recovery and must be promptly reimbursed in full within 30 calendar days, or the claimant will have additional liability for interest and all costs of collection, including reasonable at torney’s fees. The claimant will first reimburse the Fund out of any recovery before the claimant is entitled to any portion of the recovery and without regard to the extent of the recovery that has been, or may be, provided to the claimant. As noted above , the Plan has the right to recover the full amount of benefits paid by the Plan, without deductions or adjustments of any kind. For example, there is no deduction or adjustment for attorney’s fees incurred by the claimant in obtaining the settlement, judg ment, arbitration or recovery. The Plan’s lien is not reduced by any such attorney’s fees. Regardless of the sufficiency of any recovery, the Plan is not subject to any state law doctrines, including but not limited to, the common fund doctrine, which woul d purport to require the Plan to reduce its recovery by any portion of a claimant’s attorney’s fees and costs. The Plan is also not subject to the make whole doctrine or other similar doctrines which purport to subject the Plan’s recovery to the claimant’s full compensation for all of his Injuries. In the event the claimant fails to reimburse the Fund from proceeds received from a third party, the Fund will also have the right to withhold future benefits equal to the amount otherwise due the Fund, plus inte rest and the costs of collection including attorneys’ fees incurred by the Fund. Reimbursement and Consent to Lien Every claimant, on whose behalf an advance may be payable, must execute and deliver to the Fund a Reimbursement Agreement and Consent to Lien in the form provided without alteration. Claimants must do whatever is necessary to protect the Fund in obtaining reimbursement and/or its subrogation rights. Each such claimant must promptly notify the Fund Office if he or she makes a claim or brings an action against a third party or if he or she obtains any settlement, judgment, or other recovery from any source. If a claimant does not execute a Reimbursement Agreement or Consent to Lien for any reason, it will not waive, compromise, diminish, release o r otherwise prejudice any of the Fund’s reimbursement rights if the Fund, at its discretion, makes an advance and inadvertently pays benefits in the absence of a Reimbursement Agreement. The Fund’s standard administrative procedure will be used to determin e whether a third party might potentially be held liable in connection with an accident or injury. Claims will not be paid until this determination is made. If it is determined that the claim may be the result of a third party’s negligence or other miscond uct, the Fund will not process any claims without a properly signed Reimbursement

69 Agreement and Consent to Lien along with acknowledgement by the claimant’s attorney, both executed without alteration or other conditions. Sources of Payment The Plan’s sourc es of payment through subrogation or reimbursement are as follows: • Money from a responsible party or third party that you, your family members, your guardian, or other representatives or beneficiaries receive or are entitled to receive; • Any constructive trust that is imposed on the proceeds of any settlement, verdict or other amount that you, your family members, your guardian, or other representatives or beneficiaries receive; • Any liability or other insurance (for example, uninsured motorist, underinsure d motorist, medical payments, no - fault, school, homeowners, or excess or umbrella coverage) that is paid or payable. Cooperation with the Plan by All Covered Persons By accepting an advance for related claim payment, every claimant agrees to do nothing tha t will waive, compromise, diminish, release or otherwise prejudice the Fund’s reimbursement rights. By accepting an advance payment for related claims to an injury, every claimant agrees to notify and consult with the Board of Trustees, its Fund Office or designee before: • Starting any legal action or administrative proceeding against a third party based on any alleged negligent, intentional or otherwise wrongful action that may have caused or contributed to the claimant’s injury that resulted in the Fund’s advance payment of claims; or • Entering into any settlement agreement with that third party or that third party’s insurer that may be related to any actions by that third party that may have caused or contributed to the claimant’s injury that resulted in th e Fund’s advance for claims related to such injury. By accepting an advance in claim payments, every claimant agrees to keep the Board of Trustees, its Fund Office or designee informed of all material developments with respect to all such claims, actions, or proceedings. Your Responsibilities You have the duty to cooperate fully with the Plan and any party designated by the Plan Administrator if the Plan’s rights of subrogation or reimbursement are asserted, including executing and delivering any documents the Plan may require or appearing in court for a deposition or testimony, if necessary. You must do nothing to prejudice the Plan’s rights of subrogation and reimbursement. When making or filing a claim, you or your legal representative must give the Plan written notice about whether or not you were injured by a third party. You also must provide the following information in a timely manner: • The name, address and telephone number of:  The third party who in any way caused the injury, as well as the attorney representing the third party;  The third party’s insurer; and  The attorney who represents you with respect to the third party’s act or omission. • Before any meeting, the date, time and location of the meeting between the third party or his or her attorney an d yourself or your attorney; • All terms of any settlement offer made by the third party or his or her insurer;

70 • All information you or your attorney discovered concerning the third party’s insurance coverage; • The amount and location of any funds you recover from the third party or his or her insurer, and the dates on which such funds were received; • All information related to any oral or written settlement agreement between you and the third party or his or her insurer; • All information regarding any legal action that has been brought on your behalf against the third party or his or her insurer; and • All other information the Plan may request. All Recovered Proceeds Are to Be Applied to Reimbursement of the Fund By accepting an advance payment of claims for a n injury, every claimant agrees to reimburse the Fund for all such advances by applying any and all amounts paid or payable to them by any third party or that third party’s insurer by way of settlement, judgment, arbitration or recovery, or in satisfaction of any judgment or agreement, regardless of whether those proceeds are characterized as being paid on account of the medical expenses for which any advance has been made by the Fund. The Fund will have the right to recover from the claimant the full amoun t of benefits paid without deductions or adjustments of any kind including attorney’s fees. In such event, the Fund must be fully reimbursed within 30 calendar days of the date proceeds are received by the claimant or his attorney, or the claimant will hav e additional liability for interest and all costs of collection, including reasonable attorney’s fees. The Fund may offset future claims/benefits in order to receive the full amount of benefits paid if full reimbursement is not made. Furthermore, once the claim is settled and further liability is closed, the Fund is not liable for, and will not pay, future benefits for claims related to that injury or accident. Note: This Fund is a self - insured employee welfare benefit plan and, therefore, ERISA preempts any state law purporting to restrict the Fund’s right under this provision. Furthermore, any state law directed at insurance companies will not apply to the Fund since it is self - insured. No - Fault Insurance Coverage Where the participant or eligible depend ent is involved in a motor vehicle accident covered by a no - fault insurance policy, whether or not required by state insurance law, the automobile no - fault insurance carrier will initially be liable for lost wages, medical, surgical, hospital and related c harges and expenses up to the greater of: • The maximum amount of basic reparation benefit required by applicable law; or • The maximum amount of the applicable no - fault insurance coverage in effect. The Plan will thereafter consider any excess charges and exp enses under the applicable provisions of the respective Plan in which you are provided health coverage. Before related claims will be paid through the Fund, the participant or his/her eligible dependent will be required to sign a Reimbursement Agreement an d Consent to Lien. If the participant or his/her eligible dependent fails to secure no - fault insurance as required by state law, the participant or eligible dependent is considered as being self - insured and must pay the amount of the basic medical reparati on expenses for himself and/or his eligible dependents arising out of the accident.

71 Refund of Overpayment of Benefits — Right of Recovery If the Fund pays benefits for expenses incurred on account of you or your Eligible Dependent, you or any other perso n or organization that was paid must make a refund to the Fund if: • All or some of the expenses were not paid or did not legally have to be paid by you or your eligible dependents; • All or some of the payment made by the Fund exceeds the benefits under the P lan; or • All or some of the expenses were recovered from or paid by a source other than this Plan including another plan to which this Plan has secondary liability under the Coordination of Benefits provisions. This may include payments made as a result of claims against a third party for negligence, wrongful acts or omissions. The refund will equal the amount the Fund paid in excess of the amount it should have paid under the Plan. In the case of recovery from or payment by a source other than this Plan, th e refund equals the amount of the recovery or payment up to the amount the Fund paid. If you or any person or organization that was paid does not promptly refund the full amount, the Fund may reduce the amount of any future benefits that are payable under the Plan. The reductions will equal the amount of the required repayment, plus interest. The Fund may have other rights in addition to the right to reduce future benefits.

72 Claims Filing and Appeal Procedures This Section of the SPD describes the procedur es for filing claims and benefits as provided under the terms of the National IAM Benefit Trust Fund. It also describes the procedures for you to follow if your claim is denied in whole or in part and you wish to appeal the decision. The Plan’s internal cl aims and appeal procedures are designed to provide you with full, fair, and fast claim review and so that Plan provisions are applied consistently with respect to you and other similarly situated participants. In addition, the Plan must consult with a heal th care professional with appropriate training and experience when reviewing an adverse benefit determination that is based in whole or in part on a medical judgment (such as a determination that a service is not medically necessary or appropriate, or is E xp erimental or Investigational). The internal claims process pertains to determinations made by the appropriate Claims Administrator about whether a request for benefits (known as a “claim”) is payable. If the appropriate Claims Administrator denies your claim for benefits (known as an “adverse benefit determination”), you have the right to appeal the denied claim under the Plan’ s internal appeals process. For health benefits, you may be able to seek an external review with an Independent Review Organization (IRO) that conducts reviews of adverse benefit determinations either (i) after the Plan’s internal appeals process has been exhausted, or (ii) under limited circumstances before the Plan’s internal claims and appeals process have been exhauste d .

73 Right to an Authorized Representative In making a claim or appeal, you may be represented by any authorized representative. If your representative is not an attorney, parent, or court appointed guardian, you must designate the representative by a signed written statement. For this purpose, an authorized representative also includes a health care professional. An “authorized representative” means a person you authorize, in writing, to act on your behalf, such as your Spouse. The Plan will also recognize a court order giving a person authority to submit claims on your behalf, except th at in the case of a claim involving urgent care, a health care professional with knowledge of your condition may always act as your authorized representative. A form can be obtained from the Fund Office to designate an authorized representative. The Plan requires you to provide a written statement declaring your designation of an authorized representative along with the representative’s name, address, phone number, and email address. To designate an authorized representative, you must submit a completed au thorized representative form (available from the Fund Office). The Plan will honor the designated authorized representative until the designation is revoked, or as mandated by a court order. You may revoke a designated authorized representative status by s ubmitting a completed change of authorized representative form available from and to be returned to the appropriate Claims Administrator or the Fund Office. The Plan reserves the right to withhold information from a person who claims to be your authorized representative if there is suspicion about the qualifications of that individual . Adverse Benefit Determination An adverse benefit determination, for the purpose of the internal claims and appeal process, means: • A denial, reduction, or termination of, or a failure to provide or make payment in whole or in part for a benefit, including a determination of an individual’s eligibility to participate in the Plan or a determination that a benefit is not a covered benefit; • A reduction of a benefit resulting from the application of any utilization review decision, source - of - injury exclusion, network exclusion, or other limitation on an otherwise covered benefit or failure to cover an item or service for which benefits are otherwise provided because it is determine d to be not medically necessary or appropriate, or Experimental or Investigational; or • A rescission of coverage, whether or not there is an adverse effect on any particular benefit. Health Care Professional A health care professional, for the purposes of t he claims and appeals provisions, means a physician or other health care professional licensed, accredited or certified to perform specified health serv ices consistent with state law. Definition of a Claim A claim is a request for a Plan benefit made by yo u, your Spouse, or your covered Dependent Child (also referred to as “claimant”) or your authorized representative in accordance with the Plan’s reasonable claims procedures. Casual inquiries about benefits or the circumstances under which benefits might be paid according to the terms of the Plan are not considered claims. Nor is a request for a determination of whether an individual is eligible for benefits under the Plan cons idered to be a claim. However, if a claimant files a claim for specific benefits and the claim is denied because the individual is not eligible for benefits under the Plan, the coverage determination is consi dered a claim. A request for prior approval of a benefit that does not require prior approval by the Plan is not considered a claim. However, requests for prior approval of a benefit where the Plan does require prior approval (e.g., hospital pre - admission certification, etc.) are considered claims and s hould be submitted as pre - service claims (or urgent claims, if applicable), as described in the following procedures.

74 Types of Claims Health benefit claims can be filed for medical, mental health, substance use disorder, and prescription drug, benefits. Th ere are four categories of health claims as described below: Pre - Service Claim means a claim for a benefit for which the Plan requires approval before health care is obtained, or approval is required in order to receive the maximum benefit provided by the Plan. Urgent Claim means a claim for health care or treatment that if normal pre - service standards were applied, would seriously jeopardize the life or health of the Covered Person or the ability of the Covered Person to regain maximum function or, in the opinion of a physician with knowledge of the covered person’s medical condition, subject the covered person to severe pain that could not be adequately managed without the care or treatment that is the subject of the claim. However, the Plan will not deny benefits for these procedures or services if it is not possible for the claimant to obtain the pre - approval, or the pre - approval process would jeopardize the claimant’s life or health. Concurrent Claim means a claim that is reconsidered after an initial ap proval is made, resulting in a reduction, termination or extension of a benefit. (An example of this type of claim would be an inpatient hospital stay originally certified for five days that is reviewed at three days to determine if the full five calendar days stay is still appropriate. In this situation, a decision to reduce, terminate or extend the hospital stay is made concurrently with the period of hospitalization.) Post - Service Claim means a claim for benefits that is not a pre - service, concurrent or urgent claim. Specifically, a claim submitted for payment after health services or treatment have been obtained. Claim Elements A claim must include the following elements to trigger the Plan’s internal claims process : • Be written or electronically submitt ed (oral communication is acceptable for authorization of services only for Urgent Care Claims); • Be received by the Plan Administrator or Claims Administrator (as applicable); • Name a specific individual participant and his/her Social Security Number or oth er assigned unique identification number; • Name a specific claimant and his/her date of birth; • Name a specific medical condition or symptom; • Provide a description and date of a specific treatment, service or product for which approval or payment is requeste d (must include an itemized detail of charges and applicable service codes); • Identify the provider’s name, address, phone number, professional degree or license, and federal tax identification number (TIN); and • When another plan is primary payer, include a copy of the other Plan’s Explanation of Benefits (EOB) statement along with the submitted claim. A request is not a claim if it is: • Not made in accordance with the Plan’s benefit claims filing procedures described in this section; • Made by someone other th an you, your covered dependent, or your (or your covered dependent’s) authorized representative; • Made by a person who will not identify himself or herself (anonymous); • A casual inquiry about benefits such as verification of whether a service/item is a cove red benefit or the estimated allowed cost for a service;

75 • A request for prior approval where prior approval is not required by the Plan; • An eligibility inquiry that does not request benefits. However, if a benefit claim is denied on the grounds of lack of e ligibility, it is treated as an adverse benefit determination and the individual will be notified of the decision and allowed to file an appeal; • The presentation of a prescription to a retail pharmacy or mail order pharmacy that the pharmacy denies at the point of sale. After the denial by the pharmacy, you may file a claim with the Plan. If you submit a claim that is not complete or lacks required supporting documents, the Plan Administrator or Claims Administrator, as applicable, will notify you about wha t information is necessary to complete the claim. This does not apply to simple inquiries about the Plan’s provisions that are unrelated to any specific benefit claim or which relate to proposed or anticipated treatment or services that do not require prio r approval. How to File a Claim Please make sure that you present your benefit identification card to each provider before you are given any services so that the provider will know that you participate in a Cigna Open Access Plus Preferred Provider Organization. Non - Preferred Providers may require that you pay them first and that you seek reimbursement by filing your own claim with Cigna. Network Benefits If you use Cigna Open Access Plus Network providers, your claim for benefits will go directly fr om the network health care provider (hospital, physician, laboratory, etc.), through an automated electronic system, or through the mail, to the Claims Administrator for processing. Generally, you are not required to file a claim form for in - network benefi ts. Out - of - Network Benefits If you use out - of - network providers not affiliated with the Cigna Open Access Plus PPO Network, you may be required to submit your own completed claim form and follow the claims procedures outlined i n this Section, as applicabl e. You may obtain claim forms from the Fund Office, Cigna, or by going on line at www.iambtf.org . To expedite the processing of your medical claim, please be sure to complete the form thoroughly, including information about Medicare eligibility and any other group benefits that may be payable on your behalf. Your written claim must be mailed to Cigna as soon as reasonably possible after the expense is incurred, but in no event more than one year after the expense is incurred. Note: Any claims Cigna receives more than one year after the expense is incur red will be denied as untimely. Also, Cigna may h ave shorter filing limits for their network providers. You will not be responsible for payment of charges Cigna denies for untimely filing if a Cigna contracted provider fails to file your claim in accordance with Cigna’s contractual requirements. The fol lowing information must be completed on the claim form in order for your request for benefits to be considered a claim, and in order for the Plan to be able to process your claim. You complete the Employee portion of the claim form, providing the following : • Participant name; • Patient name; • Participant member id and account number • Patient date of birth; and Note: Your member ID is the ID shown on your benefit identification card.

76 Your physician (or other provider) may either : • Complete the following items, as applicable, on the Attending Physician’s Statement section of the claim form:  Date of Service;  CPT - 4 (the code for physician services and other health care services found in the Current Procedural Terminology, Fourth Edition, as maintained and distribute d by the American Medical Association);  ICD - 10 (the diagnosis code found in the International Classification of Diseases, 10th Edition, Clinical Modification as maintained and distributed by the U.S. Department of Health and Human Services);  Billed charge ;  Number of units (for anesthesia and certain other claims);  Federal taxpayer identification number (TIN) of the provider;  Billing name and address; and  If treatment is due to accident, accident details. OR • Attach all itemized bills or doctor’s statements that describe in full the services rendered. W arning: Any person who knowingly presents a false or fraudulent claim for payment of a loss or benefit may be guilty of a crime and may be subject to fines and confinement in prison. Filing a Claim You may file claims for health benefits and appeal adverse claim decisions yourself or have an authorized representative do it for you. Often, the provider will make the claim on your behalf directly to Cigna. If your claim is denied, in whole or in part, you will rec eive a written notice of the denial from Cigna. The notice will explain the reason for the denial and the review procedures, including any applicable statute of limitation within which the claimant may file a claim in a court of law. Urgent Care Claims — Submit Directly to Cigna If the Plan requires advance approval of a service, supply or procedure before a benefit will be payable, and if the Plan or your physician determines that it is an urgent care claim, you will be notified of the decision not later than 72 hours (shorter depending on medical urgency of the case) after the claim is received. The decision will be made by Cigna unless the decision relates to your eligibility to participate, in which case it will be made by the Fund Office, acting on beh alf of the Board of Trus tees. If there is not sufficient information to decide the claim, you will be notified of the information necessary to complete the claim as soon as possible, but not later than 24 hours after receipt of the claim. You will be given a reasonable additional amount of time, but not less than 48 hours, after the end of that additional time period (of after receipt o f the information, if earlier). Other Health Claims (Pre - Service and Post - Service) — Submit Directly to Cigna If the Plan req uires you to obtain advance approval of a service, supply or procedure before a benefit will be payable, a request for advance approval is considered a pre - service claim. You will be notified of the decision not later than 15 calendar days after re ceipt of the pre - service claim.

77 For other claims (post - service claims), you will be notified of the decision not later than 30 calendar days after receipt of the claim. For either a pre - service or a post - service claim, these time periods may be extended up to an a dditional 15 calendar days due to circumstances outside the Plan’s control. In that case, you will be notified of the extension before the end of the initial 15 - or 30 - calendar day period. The time period may be extended because you have not submitted suf ficient information, in which case you will be notified of the specific information necessary and given an additional period of at least 45 calendar days after receiving the notice to furnish that information. You will be notified of the Plan’s claim decis ion no later than 15 calendar days after the end of that additional period (or after receipt o f the information, if earlier). For pre - service claims which name a specific claimant, medical condition and service or supply for which approval is requested, an d which are submitted to a Plan representative responsible for handling benefit matters, but which otherwise fail to follow the Plan’s procedures for filing pre - service claims, you will be notified of the failure within five calendar days (within 24 hours in the case of an urgent care claim) and of the proper procedures to be followed. The notice may be oral unless you re quest written notification. Note: Any claim Cigna receives more than one year after the expense is incurred will be denied as untimely. Al so, Cigna may have shorter filing limits for some network providers. You will not be responsible for payment of charges Cigna denies for untimely filing if a Cigna contracted provider fails to file your claim in accordance with Cigna’s contractual requirem ents. Ongoing Course of Treatment If you have received pre certification for an ongoing course of treatment, you will be notified in advance if the Plan intends to terminate or reduce benefits for the previously authorized course of treatment so that you wi ll have an opportunity to appeal the decision and receive a decision on that appeal before the termination or reduction takes effect. If the course of treatment involves urgent care, and you request an extension of the course of treatment at least 24 hours before its expiration, you will be notified of the decision within 24 hour s after receipt of the request. Notice of Decision If your claim is denied, you will be provided with written notice of denial of the claim (whether denied, in whole or in part). Th is notice generally will be provided by Cigna, except in some cases, by the Fund Office on behalf of the Trustees. For example, if the decision relates to Plan eligi bility. This notice will state: • The claim involved. • The specific reason(s) for the determin ation. • The Plan standard that was used, if any. • The specific Plan provision(s) on which the determination is based. • A description of any additional material or information necessary to perfect or decide the claim, and an explanation of why the materi al or information is necessary. • A description of the appeal procedures (including the external appeal opportunity) and applicable time limits for pursuing the appeal or fil ing a legal claim. • A statement of your right to bring a civil action under ERISA Section 5 02(a) following an adverse benefit determination on review. • If an internal rule, guideline or protocol was relied upon in deciding your claim, you will receive either a copy of the rule, or a statement that such a rule was relied upon in deciding the claim and that a copy will be provided to you upon request at no charge.

78 • If the determination was based on the absence of medical necessity, or because the treatment was experimental or investigational, or other similar exclusion, you will receive an explanatio n of the scientific or clinical judgment for the determination applying the terms of the Plan to your claim, or a statement that it is available upon request at no charge. • If the adverse benefit determination involves urgent care, a statement of the expedi ted review process applicable to such claims. An adverse determination involving urgent care may be provided orally, provided written notification is provided not later than three calendar days after the oral notification. If a Pre - Service claim is approve d, you will receive written (or electronic, as applicable) notice within fifteen (15) days of the appropriate Claims Administrator’s receipt of the claim. Notice of Approval of an Urgent Care Claim will be provided in writing (or electronically, as applica ble) to you and your health care professional within the applicable timeframe after the Claims Administrator’s receipt of the claim. Internal Appeals for Health Claims A. First Level Appeal • Medical Benefits Appeal If you disagree with Cigna’s decision on any of your claims for medical benefits, you may submit an appeal to Cigna. Your request for appeal review must be made in writing within 180 days of receipt of your denial notice, and should be mailed to the Cigna Appeals Unit, P.O. Box 188011, Chattanooga, TN 37422 - 8011 . You should state the reason why you feel your appeal should be approved and include any information supporting your appeal. Your appeal will be reviewed by someone at Cigna not involved in the init ial decision. Note: You must first file your internal appeal with Cigna as you initiate the Appeals process. First level appeals received more than 180 days after receipt of the notice of the claim denial or adverse determination will be denied as untimely . Cigna will respond in writing to your appeal no later than 15 calendar days (for pre - service claims) or 30 calendar days (for post - service claims) after the appeal is received. In ruling on such first level appeals, Cigna serves in the capacity of a nam ed fiduciary under ERISA. • Eligibility Appeal If you are appealing an adverse determination relating to eligibility to the Board of Trustees, the Board of Trustees will make a determination at the next scheduled meeting of the Board of Trustees following the Plan’s receipt of a request for review, unless the request for review is filed within 30 calendar days preceding the date of such meeting. In such case, a benefit determination may be made no later than the date of the second meeting following the Plan ’s receipt of a request for review. If special circumstances require a further extension of time, a determination will be rendered not later than the third meeting of the Board of Trustees following the Plan’s receipt of the request for review. If such a n extension of time for review is required because of special circumstances, the Board of Trustees will notify the claimant in writing of the extension, describing the special circumstances and the date as of which the benefit determination will be made, p rior to the commencement of the extension. Notice of the benefit determination and review by the Board of Trustees will be made as soon as possible, but not later than five calendar days after the benefit determination is made. You may submit written comments, documents, records and other information relating to your claim. You may also request that the Plan provide you, free of charge, copies of all documents, records and other information relevant to the claim.

79 • Expedited Appeal Process If your claim involves urgent care, an expedited appeal may be initiated by a telephone call to Cigna Member Services located on the back of your member identification card (800 - 244 - 6224). You or your authorized representative may appeal urgent care claim denials either orally or in writing. All necessary information, including the appeal decision, will be communicated between you or your authorized representative and the Plan by telephone, fax or other similar method. You will be notified of the decision not later than 36 hours after the urgent care appeal is received. • Right to Second Level Appeal If you are dissatisfied with the appeal decision made by Cigna , you may request a second level review of your appeal. Your request for second level appeal review must be made in writing to the Board of Trustees, and be submitted to the office of the National IAM Benefit Trust Fund within 90 days of your receipt of Cigna’s denial notice on the first level appeal review. Your second level appeal should include a copy of the first level appeal denial, and any information supporting your appeal. Second leve l appeals received more than 90 d ays after receipt of the denial for the first level appeal will be denied as untimely. B. Filing a Second Level Appeal On second level, the Boa rd of Trustees will review your claim and make a decision on the date of the first meeting of the Board that immediately follows the Plan’s receipt of a request for review, unless the request for review is filed within 30 days preceding the date of such me eting. In such case, a benefit determination may be made on the date of the second meeting following the Plan’s receipt of the request for review. If special circumstances require a further extension of time for processing, a determination will be made no later than the third meeting following the initial receipt of the appeal. If an extension is required, you will be notified of the extension and the reasons for it prior to the commencement of the extension. In deciding an appeal of a benefit determinatio n that was based, in whole or in part, on a medical judgment (including determinations about whether a particular treatment, drug, or other item is experimental, investigational, or not medically necessary or appropriate), the reviewer will consult with a health care professional who has appropriate training and expertise in the particular field of medicine, and who was not consulted in connection with the original determination. You will also be provided, upon request, with the identity of any medical or v ocational experts whose advice was obtained at any level of the claims and appeals process, without regard to whether that advice was relied on. If you submit an appeal with the Board of Trustee, any applicable statute of limitations will be delayed while the appeal is pending. The filing of a claim will have no effect on your rights to any other benefits under the Plan. No fees or costs are imposed upon you as part of the appeal to the Board of Trustees. The decision to submit a denial made by Cigna to th e Board of Trustees will have no effect upon your rights to any other benefits under the P lan. If you choose to appeal to the Board of Trustees following an adverse determination at the first level of appeal by Cigna, you must do so in writing, and you sho uld send the following information: • The specific reason(s) for the appeal; • Copies of all past correspondence with the Fund, including any Explanation of Benefits (EOB’s); • Copies of the adverse appeal determination made by Cigna; and • Any applicable informa tion that you have not yet sent to the Fund Office.

80 I f you file an appeal with the Board of Trustees, you will be deemed to authorize the Fund to obtain information relevant to your claim. Mail your written appeal directly to: Board of Trustees National IAM Benefit Trust Fund 1300 Connecticut Avenue, NW, Suite 300 Washington, DC 20036 The Board of Trustees will review your appeal. They will evaluate your claim within the timeframes described above . You will be notified of the Board of Trustees decision o n your appeal within 5 calendar days after the date your appeal is reviewed. Prescription Drug Benefit Claims There are separate procedures for making claims for the Prescription Drug Benefit, including a special procedure to fill prescriptions for Specia lty Medications. You do not have to complete a written claim form if you have a CVS Caremark prescription card and use a participating pharmacy. If any claim for a prescription drug benefit is denied, you have the right to appeal by following the procedure s explained below. You may get your general prescriptions filled at any participating pharmacy by presenting your CVS Caremark prescription card to the pharmacist. CVS Caremark will treat the claim as a Post - Service Claim set forth in the medical benefit claims provisions above. Any prescription drug claim CVS Caremark receives more than one year after the date of purcha se will be denied as untimely. Specialty Medications Specialty Medications can be filled by using only CVS Caremark Specialty Pharmacy Se rvices. Claims for Specialty Medications are treated as Pre - Service Claims because you must get prior authorizati on as a condition of coverage. If you are prescribed a Specialty Medication, or if your pharmacist tells you that an item you are requesting i s a Specialty Medication, you must call CaremarkConnect  toll - free at 800 - 237 - 2767. When notified, CVS Caremark will contact your physician or Allied Health Professional directly to obtain clinical information needed to perform a prior authorization review, and you will not have to complete a written claim form. CVS Caremark Specialty Pharmacy Services include a program called ACSF, which means Advanced Control Specialty Formulary . With ACSF, in addition to the required medical necessit y review, Specialty Medications will also be reviewed to determine whether a preferred alternative exists that should be tried first. If an alternative is available, it will be discussed with your physician or Allied Health Professional and the script chan ged. This is part of the prior authorization process which will be transparent to you. CVS Caremark will notify you in writing of its determination on your claim for coverage of a Specialty Medication within a reasonable period of time, but no later than 1 5 calendar days after it receives notification of the claim. This period may be extended by one 15 - day period, if special circumstances beyond CVS Caremark ’s control require that additional time is needed to process your claim. If an extension is needed, CVS Caremark will notify you in writing before the expiration of the initial 15 - day period of the circumstances requiring an extension and the date by which it expects to reach a decision. If the extension is required because additional information is need ed from you to decide the claim, the notice of extension will specifically describe the information that is needed from you, and you will be given at least 45 days from your receipt of the notice within whi ch to provide the information.

81 If your claim for a Specialty Medication is an Urgent Claim, you will be notified of CVS Caremark ’s determination more quickly. The definition of an Urgent Claim is as set forth in the health benefit claims section above. For Urgent Claims for Specialty Medication, CVS Care mark will notify you of its determination as soon as possible, taking into account the medical exigencies, but no later than 72 hours after you first call CVS Caremark about the prescription for the Specialty Medication, unless you or your physician fail t o provide sufficient information to make the determination, in which case you will be notified within 24 hours of the information that is needed. The determination will then be made no more than 24 hours after CVS Caremark receives the information. Appeal s of Prescription Drug Claims Denied by CVS Caremark A. First Level Appeal If you disagree with a determination made by CVS Caremark on any prescription drug claim, you must first submit a request for appeal by contacting CVS Caremark customer care at 800 - 282 - 8503 within 180 days of receipt of your denial notice. You should state the reason why you believe your appeal should be approved and include any information supporting your appeal. First level appeals received more than 180 days after the date you receiv e the denial or adverse determination notice of the claim will be denied as untimely. Non - Specialty Drugs: For appeals of denied claims that do not involve Specialty Drugs, CVS Caremark will notify you of a decision within 30 days of receip t of your request for review. Specialty Drugs: For appeals not involving Urgent Claims, CVS Caremark will notify you of its decision within a reasonable period of time appropriate to the medical circumstances, but in no event will CVS Caremark take more t han 15 days to notify you of its decision. Urgent Claim: If the Specialty Medication appeal involves a denied Urgent Claim, CVS Caremark will decide the appeal as soon as possible, taking into account the medical exigencies, but no later than 72 hours aft er receipt of the appeal. If CVS Caremark denies your appeal, you have the right to request a second level appeal with the Board of Trustees of the National IAM Benefit Trust Fund . B. Second Level Appeal If CVS Caremark denies your appeal, you have the right to request a second level appeal with the Board of Trustees of the National IAM Benefit Trust Fund. You should submit your second level appeal to the Fund Office after you receive the first level appeal denial, but w ithin 9 0 days of receipt of CVS Caremark’s denial notice on the first level appeal review . Your second level appeal should include a copy of the first level appeal denial , and any information supporting your appeal. Second lev el appeals received more than 9 0 days after rec e ipt of the first level appeal denial notice will be denied as untimely. The Board of Trustees will review your appeal on the date of the first Board meeting that immediately follows the Plan’s receipt of your request for review, unless the request for review is filed within 30 days preceding the date of such meeting. In such case, a benefit determination may be made on the date of the second meeting following the Plan’s receipt of the request for review. If special circumstances require a further extension of time for processing, a determination will be made no later than the third meeting following the initial receipt of the appeal. If an extension is required, you will be notified of the extension and the reasons for it prior to the co mmencement of the extension. If the Specialty Medication appeal is related to a denied Urgent Claim, the final decision on the appeal will be made as soon as possible, taking into account the medical exigencies, but no later than 72 hours after receipt of the appeal by the Fund Office.

82 External Review of Adverse Benefit Determination after Internal Appeal Generally, health benefit claims are handled directly by Cigna if you use a provider in the Cigna Open Access Plus network. After you have exhausted the Plan’s internal claims and appeals process, you may exercise your option to seek an external review with an Independent Review Organization (IRO) that conducts reviews of adverse benefit determinations. This External Review process is intended to comply with the Affordable Care Act’s external review requirements. If you are not literate in English, depending on the county in which you reside, you may be eligible for assistance in the non - English language in which you are literate. Call the Fund Office at 202 - 785 - 8148 or toll - free at 800 - 457 - 3481 for more information. The External Review Process Works as Follow s : If your appeal of a claim is denied, whether it’s a pre - service, post - service, or urgent care claim, you may request further review by an Independ ent Review Organization (IRO) as described below. You may only request external review after you have exhausted the internal review and appeals process described above. NOTE: External review is only available for the following types of claim denials : • A den ial that involves medical judgment, including, but not limited to, those based on the Plan’s requirements for medical necessity, appropriateness, health care setting, level of care or effectiveness of a covered benefit, or a determination that a treatment is experimental or investigational. The IRO will determine whether a denial involves a medical judgment; and • A denial due to a rescission of coverage (retroactive elimination of coverage), regardless of whether the rescission has any effect on any particul ar benefit at that time. External review is not available for any other types of denials, including if your claim was denied due to your failure to meet the requirements for eligibility under the terms of the Plan. Under limited circumstances, you may be able to seek external review before the internal claims and appeals process has been completed: • If the Plan waives the requirement that you complete its internal claims and appeals process first. • In an urgent care situation (see “Expedited External Review o f Claim s ”). Generally, an urgent care situation is one in which your health may be in serious jeopardy or, in the opinion of your health care professional, you may experience pain that cannot be adequately controlled while you wait for a decision on your internal appeal. • If the Plan has not followed its own internal claims and appeals process and the failure was more than a minor error. In this situation, the internal claims and appeal is “deemed exhausted,” and you may proceed to external review. If you think that this situation exists, and the Plan disagrees, you may request that the Plan explain in writing why you are not entitled to seek external review at this time. Your request for external review of a denial must be made, in writing, within four (4 ) calendar months of the date that you receive the denial. Because the Plan’s internal review and appeals process generally must be exhausted before external review is available, typically external review of claims will only be available for denials of app eals (and not initial claim denials).

83 1. Preliminary Review a. Within five (5) business days of the Plan’s receipt of your external review request for a claim, the Plan will complete a preliminary review of the request to determine whether:  You are/were covered under the Plan at the time the health care item or service is/was requested or, in the case of a retrospective review, were covered under the Plan at the time the health care item or service was provided;  The denial does not relate to your failure to meet the requirements for eligibility under the terms of the Plan;  You have exhausted the Plan’s internal claims and appeals process (except, in limited, exceptional circumstances); and  You have provided all of the information and forms required to process an external review. b. Within one business day of completing its preliminary review, the Plan will notify you in writing as to whether your request meets the threshold requirements for external review. If applicable, this notification will inform you:  If your request is complete and eligible for external review, or  If your request is complete but not eligible for external review, in which case the notice will include the reasons for its ineligibility, and contact information for the Employee Benefits S ecurity Administration (toll - free number (866) 444 - EBSA (3272)), or  If your request is not complete, in which case the notice will describe the information or materials needed to make the request complete, and allow you to perfect the request for external review within the four - month filing period, or within a 48 - hour period following receipt of the notification, whichever is later. 2. Review by Independent Review Organization If the request is complete and eligible, the Plan will assign the request to an Ind ependent Review Organization or “IRO.” The IRO is not eligible for any financial incentive or payment based on the likelihood that the IRO would support the denial of benefits. The Plan has contracted with more than one IRO, and generally rotates assignmen t of external reviews among the IROs with which it contracts. Once the claim is assigned to an IRO, the following procedure will apply:  The assigned IRO will timely notify you in writing of the request’s eligibility and acceptance for external review, inc luding directions about how you may submit additional information regarding your claim (generally, such information must be submitted within ten (10) business days).  Within five (5) business days after the assignment to the IRO, the Plan will provide the I RO with the documents and information it considered in making its denial determination.  If you submit additional information related to your claim, the assigned IRO must within one business day forward that information to the Plan. Upon receipt of any such information, the Plan may reconsider its denial that is the subject of the external review. Reconsideration by the Plan will not delay the external review. However, if upon reconsideration, the Plan reverses its denial, it will provide written notice of i ts decision to you and the IRO within one business day after making that decision. Upon receipt of such notice, the IRO will terminate its external review.  The IRO will review all of the information and documents timely received. In reaching a decision, th e IRO will review the claim de novo (as if it is new) and will not be bound by any decisions or conclusions reached during the Plan’s internal claims and appeals process. However, the IRO will be bound to observe the terms of the Plan to ensure that the IR O decision is not contrary to the terms of the Plan, unless the terms are inconsistent with applicable law. The IRO also must

84 observe the Plan’s requirements for benefits, including the Plan’s standards for clinical review criteria, medical necessity, appr opriateness, health care setting, level of care, or effectiveness of a covered benefit. In addition to the documents and information provided, the assigned IRO, to the extent the information or documents are available and appropriate, may consider addition al information, including information from your medical records, any recommendations or other information from your treating health care providers, any other information from you or the Plan, reports from appropriate health care professionals, appropriate practice guidelines, the Plan’s applicable clinical review criteria and/or the opinion of the IRO’s clinical reviewer(s), unless such requirements are inconsistent with applicable law.  The assigned IRO will provide written notice of its final external revi ew decision to you and the Plan within 45 calendar days after the IRO receives the request for the external review.  The assigned IRO’s decision notice will contain the following information, unless such information is inconsistent with applicable current l aw: › A general description of the reason for the request for external review, including information sufficient to identify the claim (including the date or dates of service, the health care provider, the claim amount (if applicable), the diagnosis code and its corresponding meaning, and the treatment code and its corresponding meaning, and the reason for the previous denial); › The date that the IRO received the assignment to conduct the external review and the date of the IRO decision; › References to the evide nce or documentation, including the specific coverage provisions and evidence - based standards, considered in reaching its decision; › A discussion of the principal reason(s) for its decision, including the rationale for its decision and any evidence - based st andards that were relied on in making its decision; › A statement that the determination is binding except to the extent that other remedies may be available to you or the Plan under applicable state or federal law; › A statement that judicial review may be av ailable to you; and › Current contact information, including phone number, for any applicable office of health insurance consumer assistance or ombudsman established under the Public Health Services Act to assist with external review processes. Expedited Ext ernal Review of Claims You may request an expedited external review if: • You receive an initial claim denial that involves a medical condition for which the timeframe for completion of a non - expedited internal appeal would seriously jeopardize your life or health, or would jeopardize your ability to regain maximum function, and you have filed a request for an expedited internal appeal; or • You receive a denial from an appeal that involves a medical condition for which the timeframe for completion of a standar d external review would seriously jeopardize your life or health or would jeopardize your ability to regain maximum function; or, you receive a denial from an appeal that concerns an admission, availability of care, continued stay, or health care item or s ervice for which you received emergency services, but you have not yet been discharged from a facility. Preliminary Review Immediately upon receipt of the request for expedited external review, the Plan will complete a preliminary review of the request to determine whether the requirements for preliminary review set forth above, in Section 1(a), are met. The Plan will immediately notify you as to whether your request for review meets the preliminary review requirements, and if not, will provide or seek the information described above in Section 1(b).

85 Review by Independent Review Organization Upon a determination that a request is eligible for expedited external review following the preliminary review, the Plan will assign an IRO. The Plan will expeditiously provide or transmit to the assigned IRO all necessary documents and information that it considered in denying the claim. The assigned IRO, to the extent the information or documents are available and the IRO considers them appropriate, must consider the in formation or documents described in the procedures for standard review, previously. In reaching a decision, the assigned IRO must review the claim de novo (as if it is new) and is not bound by any decisions or conclusions reached during the Plan’s internal claims and appeals process. However, the IRO will be bound to observe the terms of the Plan to ensure that the IRO decision is not contrary to the terms of the Plan, unless the terms are inconsistent with applicable law. The IRO also must observe the Plan ’s requirements for benefits, including the Plan’s standards for clinical review criteria, medical necessity, appropriateness, health care setting, level of care, or effectiveness of a covered benefit, unless such requirements are inconsistent with applica ble law. The IRO will provide notice of the final external review decision, in accordance with the requirements set forth in this Section, as expeditiously as your medical condition or circumstances require, but in no event more than 72 hours after the IRO receives the request for an expedited external review. If the notice is not in writing, within 48 hours after the date of providing that notice, the IRO must provide written confirmation of the decision to you and the Plan. After External Review If, upon external review, the IRO reverses the Plan’s denial, upon the Plan’s receipt of notice of such reversal, the Plan will immediately provide coverage or payment for the reviewed claim. However, even after providing coverage or payment for the claim, the Plan may, in its sole discretion, seek judicial remedy to reverse or modify the IRO’s decision. If the final external review upholds the Plan’s denial, the Plan will continue not to provide coverage or payment for the reviewed claim. If you are dissatisfied wi th the external review determination, you may seek judicial review as permitted under ERISA Section 502(a). Elimination o f Conflict of Interest To ensure that the persons involved with adjudicating claims and appeals (such as claim processors and medical experts) act independently and impartially, decisions related to those persons’ employment status (such as decisions related to hiring, compensation, promotion, termination or retention), will not be made on the basis of whether that person is likely to su pport a denial of benefits. Facility of Payment If the Board of Trustees or its designee determines that you cannot submit a claim or prove that you or your covered Dependent paid any or all of the charges for health care services that are covered by the P lan because you are incompetent, incapacitated, the Plan may, at its discretion, pay Plan benefits directly to the health care professional(s) who provided the health care services or supplies, or to any other individual who is providing for your care and support. Any such payment of Plan benefits will completely discharge the Plan’s obligations to the extent of that payment. Neither the Plan, Board of Trustees, appropriate Claims Administrator nor any other designee of the Plan will be required to see to t he application of the money so paid. Board of Trustee and IRO Decisions are Final and Binding The decision of the Board of Trustees and the IRO are final and binding on all parties, including anyone claiming a benefit on your behalf. Only as limited by th e IRO, the Board of Trustees of the National IAM Benefit Trust Fund has full discretion and authority to determine all matters relating to the benefits provided under this Plan including, but not limited to, all questions of coverage, eligibility, and meth ods of providing or arranging for benefits, as well as full discretion and authority over the standard of proof required for any claim and

86 over the application and interpretation of the Plan. The Fund Office maintains records of determinations on appeals a nd Plan interpretations so that those determinations and interpretations may be referred to in future cases with similar circumstances to maintain consistency . Right to Judicial Review ERISA, Section 502(a) establishes your right to seek judicial review of your adverse determination of your benefit claim after you have exhausted your internal review and appeal procedures except where the plan (or plan sponsor) has violated a specific ERI SA standard of conduct. If the Board of Trustees or the IRO deny your appeal in whole or in part and you decide to seek judicial review, the decisions made by the Trustees or the IRO are subject to limited judicial review to determine only whether the dec ision was arbitrary and capricious. No evidence may be used in court unless it was first submitted to the Board of Trustees or to the IRO.

87 Miscellaneous Provisions and Cost Savings Advice Misrepresentation and Fraud In the event you, your Spouse, or your Eligible Dependent Children receives benefits as a result of misleading representation or any type of false information or other fraudulent representations to the Fund, you, your Spouse, or your Eligible Dependent Child will be liable to repay all amounts paid by the Fund. Fraud includes a person’s failure to disclose any other group health coverage in which such person is entitled to receive reimbursement of a claim submitted to the Fund for payment or reimbursement from a third party (See the Section on Third Party Liability for more information). You, your Spouse, or your adult dependent children will be prosecuted for fraud and held liable for all costs of collection, including interest, court, and attorney’s fees. In addition, you may be subject to cri m inal penalties. Overpayments and Erroneous Payments If a claim payment is made to a participant or assigned to a provider and it is later determined that the payment is an overpayment or an erroneous payment, the Board of Trustees may offset future claim payments or take any other action it deems appropriate in order to recover the ov erpayment or erroneous payment. Notices Sent to Addresses of Participants The Board of Trustees and/or the Fund Office will give notice by mail to participants of actions take n with respect to eligibility, claim s, and other important matters. All such notices will be sent to your address, as it appears in the Fund’s records. To protect yourself and your rights, you must be sure the Fund Office always has your current address. I f you fail to notify the Fund Office of your current address, you may miss receiving an important notice and might lose valuable rights or benefits. You may even lose coverage. Any notice sent to you at the address in the Fund’s records will be deemed to h ave been received by you. The time in which you must reply to such a notice will not be extended, because you did not give the Fund Office your current address. Cost Savings Advice Physician’s Fees and Treatment Plans Whenever possible, you should use an i n - network physician, hospital, laboratory or imaging provider. If you use an out - of - network provider, you should ask your physician about his/her treatment and medical fees, as it is important to know whether the Fund will recognize these fees as “reasonab le and customary, medically necessary, or covered charges.” Remember that coverage under the Plan for out - of - network services is limited and subject to out - of - network deductibles and coinsurance , and in some cases out - of - network services may not be covered . You are liable for charges billed by a physician or other provider that are in excess of the allowable covered charges under the Plan, and such amounts will not count towards your annual out - of - pocket maximum. You do not have this risk of being billed ab ove the allowance recognized by the Fund if you utilize a provider from the Cigna Open Access Plus (OAP) PPO network.

88 Bills and Unnecessary Services Review any out - of - network medical bills, if any, and your Explanation of Benefit (EOBs) forms for in - netwo rk claims thoroughly to assure correct charges and payments. When deciding upon the methods for treatment, avoid requesting unnecessary services. For example, you may reduce your expenses by: • Avoiding weekend hospital admissions; • Getting a second surgical opinion; • Taking advantage of outpatient surgery; • Contacting the Fund’s Utilization Review Program; and • Using generic drugs, whenever available. By adhering to these suggestions, you may utilize your benefit to its fullest, while simultaneously cutting medical costs. Reliance on Coverage Advice If you contact CVS Caremark , Cigna or the Fund Office to determine if a particular service, procedure or medication is a covered expense, including eligibility and other advice, unless you receive written confirma tion, the Plan is not necessarily responsible for these representations. If there is any question about eligibility for coverage of a specific service, procedure, or prescription drug, you should not rely on any verbal representation from CVS Caremark, Cig na or the Fund Office, but request confirmation in writing to assure that there will be no misunderstandings. Use and Disclosure of Protected Health Information The Plan maintains a “Privacy Notice” describing how your medical information may be used or di sclosed, as well as how you may gain access to your medical information and your other rights regarding that information. The Plan’s Privacy Notice is reproduced here for your careful review: Privacy Notice Section 1: Purpose of This Notice and Effective D ate THIS NOTICE DESCRIBES HOW MEDICAL INFORMATION ABOUT YOU MAY BE USED AND DISCLOSED AND HOW YOU CAN GET ACCESS TO THIS INFORMATION.

Treatment is the provision, coordination, or management of health care and related services. It also includes but is not limited to consultations and referrals between one or more of your providers. For example, the Fund may disclose to a treat ing orthodontist the name of your treating dentist so that the orthodontist may ask for your dental x - rays from the treating dentist. Payment includes, but is not limited to, actions to make coverage determinations and payment (including billing, claims ma nagement, subrogation, Fund reimbursement, reviews for medical necessity and appropriateness of care, utilizatio n review and preauthorization). For example, the Fund may tell a doctor whether you are eligible for coverage or what percentage of the bill wil l be paid by the Plan.

Once t he Fund is notified that you choose to invoke any of the individual rights listed below, it will notify the appropriate vendor on your behalf.

The Fund must provide the requested information within 30 days if the information is maintained on site or within 60 days if the information is maintained offsite. A single 30 - day e xtension is allowed if the Fund is unable to comply with the deadline. You or your personal representative will be required to complete a form to request access to the PHI in your designated record set. A reasonable fee may be charged. You may contact the Privacy Official at the address and phone number listed above. Under limited circumstances, access may be denied.

The Fund is allowed a single 30 - day extension if the Fund gives you a written statement of the reasons for the delay and the date by which the accounting will be pro vided. If you request more than one accounting within a 12 - mont h period, the Fund may charge a reasonable, cost - based fee for each subsequent ac counting. Your Personal Representative You may exercise your rights through a personal representative. Your personal representative will be required to produce evidence of aut hority to act on your behalf before the personal representative will be given access to your PHI or be allowed to take any action for you. Proof of such authority will be a completed, signed and approved Appointment of Personal Representative form. You may obtain this form by calling the Fund Office.

The Fund will recognize certain individuals as personal representatives without you having to complete an Appointment of Personal Representative form. For example, absent notice of restrictions under the Fund’s Right to Reque st Restrictions on the Use and Disclosure Policy and Procedures, the Fund will automatically consider a Spouse to be the personal representative of an i ndividual covered by the plan. In addition, the Fund will consider a parent, guardian or other person acting in loco parentis as the personal representative of an unemancipated minor unless applicable law requires otherwise. A Spouse or a parent may act on an individual’s behalf, including requesting access to their PHI. Spouses and uneman cipated minors may, however, request that the Fund restrict access of PHI to family members as described above at the beginni ng of Section 3 of this Notice.

96 General Benefit Provisions Statement Regarding Newborns and Mothers Health Protection Act The Plan will pay benefits for Pregnancy on the same basis as an illness or injury. Under federal law, group health plans may not restrict benefits for any Hospital stay in connection with chil dbirth for the mother or newborn child to less than 48 hours following vaginal delivery, or less than 96 hours following a delivery by cesarean section. However, the Plan may pay for a shorter stay if the attending provider (e.g., physician, nurse midwife, or physician assistant), after consultation with the mother, discharges the mother or newborn earlier. Also, under federal law, plans may not set the level of benefits or out - of - pocket costs so that any later portion of the 48 - hour (or 96 - hour) stay is tr eated in a manner less favorable to the mother or newborn than a ny earlier portion of the stay. In addition, the Plan may not, under federal law, require that a physician or other health care provider obtain authorization for prescribing a length of stay o f up to 48 hours (or 96 hours). However, to use certain providers or facilities, or to reduce your out - of - pocket costs, you may be require d to obtain precertification.

The National IAM Benefit Trust Fund will not be bound by any oral representations that are inconsistent with the contents of this SPD , and you should not rely on any oral representations that are inconsistent with the terms of this Plan. None of the benefits provided un der this Plan are vested. No Fund Liability The use of services of any Hospital, physician or other provider of health care, whether designated by the Plan or otherwise, is your voluntary act. Nothing in this SPD is meant to be a recommendation or instruction to use any provider. You should select a provider or course of treatment based on all appropriate factors, only one of which is coverage by the Pla n. Providers are independent contractors, not employees of the Fund. The Trustees make no representation regarding the quality of service or treatment of any provider and are not responsible for any acts of commission or omission of any provider in connect ion with Plan coverage. The provider is solely responsible for the services and treatments rendered. The Fund, the Board of Trustees, or any of their designees are not engaged in the practice of medicine, nor do any of them have any control over any diagno sis, treatment, care or lack thereof, or over any health care services provided or delivered to anyone by any health care provider. Neither the Fund, the Board of Trustees, nor any of their designees, have any liability whatsoever for any loss or injury ca used to anyone by any health care provider by reason of negligence, by failure to provide c are or treatment, or otherwise. Right to Amend The Board of Trustees has complete discretion to amend or modify this Plan or the Trust Agreement or any of the provis ions of this Plan or the Trust Agreement in whole or in part at any time.

The benefits under the Plan are not guaranteed and are provided only from assets of the Benefit Trust Fund collected and available for such purposes. Er roneous Benefit Payments Every effort will be made to ensure accuracy in the payment of your benefits. If an error is discovered, however, and it is determined that the Fund has paid any benefits that you are not entitled to, the Trustees have the right to seek repayment from you, including the right to reduce future benefit payments by the a mount of the erroneous payment.

100 No Assignment of Benefits You may not assign your benefits under this Plan except that you may direct that benefits payable to you be pa id directly to an institution or provider of medical care. However, the Fund is not legally obligated to accept such a direction from you, and no payment by the Fund to a provider can be considered a recognition by the Fund that it has a legal duty to pay the provider, except to the extent that it chooses to do so. Direct payment to an institution or provider of medical care does not waive the anti - as signment clause under the Plan. Plan Termination The Trustees may terminate the Fund through a written docum ent. The Fund may be terminated if, in the opinion of the Trustees, the Trust Fund is not adequate to meet the payments due or which may become due. The Fund may also be terminated if there are no longer any collective bargaining agreements requiring contr ibutions to the Fund.

No part of the assets or income of the Fund will be used for purposes other than for the exclusive benefit of the Employees and dependents or the Fund’s administrative expenses. Under no c ircumstances will any portion of the Fund revert or inure to the benefit of any contributing Employer or the union, either directly or indirectly. Savings Clause If any provision of this Plan is held to be unlawful, or unlawful as to a particular person or circumstance, such finding shall not adversely affect the application of the other provisions of the Plan as they are described in this SPD , unless the illegality makes the continued op eration of the Plan impossible. Source of Plan Funding The benefits under the Plan are funded by monthly contribution payments by the Employers. There also are circumstances in which Employees self - pay to the Fund. In addition, the Trustees have purchased stop loss insurance to cover losses to the Fund in the event of large claims. The stop loss insurance is provided by Amalgamated Life Insurance Company: Amalgamated Life Insurance Company 333 Westchester Avenue White Plains, NY 10604 914 - 367 - 5000 The continuation of this insurance arrangement is at the discr etion of the Trustees. Benefits are provided only to the extent permitted by the contributions. If contributions are not sufficient to maintain benefits, the Board of Trustees (Board) reserves the right to change the eligibility rules, reduce or change the benefits, or eliminate the Plan, in whole or in part. The amount of contributions and the Employees on whose behalf contributions are made are determined by the provisions of the collective bargaining agreements or other agreements, as approved by the Tru stees. The Employer must make the required payments for a month for coverage to be provided for the period. The Trustees reserve the right to terminate the participation of any Emplo yer at any time for any reason.

101 All contributions and income from earnings are used exclusively for providing benefits to eligible Employees and their dependents, and for paying expenses incurred with respect to the operation of the Fund. Erroneous Contributions Once contributions are made to the Fund, they may be returned to an Employer, at the Trustees’ discretion, only upon the Employer’s written request and only if the Employer conclusively demonstrates that the contributions were made in error and the result would not be an impermissible rescission. Employers may not unilate rally take a credit against a future payment. In determining whether the contributions were made in error and whether a refund will be made, the Trustees will consider all circumstances, including the period of time that has elapsed since the contributions were made. Federal law provides that coverage by group health plans may not be rescinded (cancelled) retroactively (except to the extent attributable to a failure to pay timely monthly contributions towards coverage), unless there is fraud or an individua l makes an intentional misrepresentation of material fact. In determining whether a refund of contributions will be made, the Trustees will consider whether the requested refund will result in an impermissible rescission of coverage under federal law or ap plicable regulations.

Continue Group Health Plan Coverage You have the r ight to continue group health coverage for yourself, Spouse or Eligible Dependent Child if there is a loss of coverage under the Plan as a result of a qualifying event. You or your dependents may have to pay for such coverage. Review this summary plan desc ription and the documents governing the Plan on the rules governing your COBR A continuation coverage rights. 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 Plan. The people who operate your Plan, called fiduciaries of the Plan, have a duty to do so prudently and in the intere st 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 welfare benefit or exercising your righ ts under ERISA. Enforce your Rights If your claim for a benefit is denied 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 t ime schedules. Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request materials from the Plan and do not receive them within 30 days, you may file suit in a federal court. In such a case, the court may require t he Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the con trol of the Plan Administrator. If you have a claim for benefits that is denied or ignored, in whole or in part, you may file suit in a state or federal court. In addition, if you disagree with the Plan’s decision or lack thereof concerning the qualified status of a medical child support order, you may file suit in federal court. If it should happen that Plan fiduciaries misuse the Plan’s money, or if you are discriminated against for asserting your

110 rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a federal court. The court will decide who sho uld pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous. However , in all cases including those described in the above paragraph, you must first exhaust your administrative remedies under the Plan (by following the claims and appeals procedures described in the SPD) before you may file suit in any court. Assistance with Questions If you have any questions about your Plan (for example, any questions about the processing of your claims, or allowances considered by the Plan, covered expenses, or questions regarding your eligibility), you should contact the Plan Administrato r. If you have any questions about this statement or about your rights under ERISA, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or write to the EBSA’s Office of Assistance: Office of Participant Assistance Employee Benefits Security Administration U.S. Department of Labor 200 Constitution Avenue, NW, Suite N - 5625 Washington, DC 20210 You may also obtain certain publications about your rights and respo nsibilities under ERISA by calling EBSA’s Toll - Free Employee & Employer Hotline at (866) 444 - EBSA (3272) or visit the EBSA website at www.dol.gov/dol/ebsa .
