    Existing eligibility requirements under the Dental Plan are amended, effective June 1, 1996, to provide that in order for an employee and his eligible dependents to be covered for Covered Dental Expenses (as defined in the Dental Plan) during any calendar month by virtue of rendering compensated service or receiving vacation pay in the immediately preceding calendar month (the "qualifying month"), such employee must have rendered compensated service on, or received vacation pay for, an aggregate of at least seven (7) calendar days during the applicable qualifying month. Any calendar day on which an employee assigned to an extra list is available for service but does not perform service shall be deemed a day of compensated service solely for purposes of this Section. Existing Dental Plan provisions pertaining to eligibility for and termination of coverage not specifically amended by this Section shall continue in effect.

    The following changes will be made effective as of January 1, 1999.

    (a) The maximum benefit (exclusive of any benefits for orthodonture) which may be paid with respect to a covered employee or dependent in any calendar year beginning with calendar year 1999 will be increased from $1,000 to $1,500.

    (b) The lifetime aggregate benefits payable for all orthodontic treatment rendered to a covered dependent, regardless of any interruption in service, will be increased from $750 to $1,000.

    (c) The exclusion from coverage for implantology (including synthetic grafting) services will be deleted and dental implants and related services will be added to the list of Type C dental services for which the Plan pays benefits.

    (d) Repair of existing dental implants will be added to the list of Type B dental services for which the Plan pays benefits.

    (e) One application of sealants in any calendar year for dependent children under 14 years of age will be added to the list of Type A dental services for which the Plan pays benefits.

    (f) The Plan will pay 80%, rather than 75%, of covered expenses for Type B dental services.

    (g) The Plan will establish and maintain an 800 telephone number that employees and dependents may use to make inquiries regarding the Plan.
