            414(b) or 414(c) of the Internal Revenue Code whose stock is
            publicly traded on an established securities market or otherwise.
            For this purpose, a Member is a key employee if the Member meets the

      deemed to terminate on the first date immediately following such six-month
      period."

11.   By deleting Section 4.03 in its entirety and by substituting therefor the
following:

      "4.03 EARLY RETIREMENT

            (a)   EARLY RETIREMENT BENEFIT AND COMMENCEMENT

            A Member who retires from employment with the Company before
            attainment of age 65 and who elects to have this provision apply to
            him will be entitled to an annual supplemental benefit, commencing
            on the first day of the month co-incident with or next following the
            later of such Member's actual retirement date and such other date
            selected by him that is prior to the Member's attainment of age 65
            and on or after attainment of age 60, equal to the supplemental
            benefit calculated according to the formula in Section 4.01 and
            based on Vested Credited Service and the Member's Final Average
            Earnings at the Member's actual retirement date. Such supplemental
            benefits will be reduced by 0.1667% for each complete month that the
            date of commencement of payment of benefits precedes the Member's
            attainment of age 65.

                                       3



            (b)   EARLY RETIREMENT ELECTION

            A Member can elect to have this provision apply to him by giving
            written notice to the Company of such election, which notice must be
            received by the Company by the thirtieth (30th) day following the
            date he or she is designated as eligible to participate in the
            Arrangement under Article 3. Notwithstanding the foregoing, for an
            Employee or former Employee who has been designated as Member prior
            to December 2, 2006, the written notice of such election must be
            received by the Company by December 31, 2006.

            (c)   DEFERRAL OF EARLY RETIREMENT COMMENCEMENT DATE

            A Member may extend the early retirement commencement date by filing
            with the Company a written change election in such form as the
            Company shall specify; provided, however, that (i) such election
            must be made at least 12 months prior to the date the previously
            elected early retirement commencement date is to occur; (ii) such
            election may not take effect until at least 12 months after the date
            on which the election is made; and (iii) the new retirement
            commencement date must be no earlier than five (5) years from the
            previously elected early retirement commencement date."

12.   By adding a new Section 4.05, as follows:

      "4.05 SUSPENSION OF CERTAIN BENEFITS FOR SECTION 409A COMPLIANCE

            Notwithstanding any other provision of the Arrangement to the
            contrary, any payment of benefits due to, or on behalf of, a Member
            who is a Specified Employee during the six-month period immediately
            following his termination of employment (or, if earlier, his death)
            shall be suspended and such suspended amounts shall be paid in a
            lump sum as soon as practicable following the expiration of such
            six-month period (or, if earlier, his death)."

13.   By adding a new Section 8.17, as follows:

      "8.17 CLAIMS PROCEDURES

            (a)   NOTICE OF DENIAL

                  If a Member or a Beneficiary is denied a claim for benefits
                  under the Plan, the Company shall provide to the claimant
                  written notice of the denial within ninety (90) days
                  (forty-five (45) days with respect to a denial of any claim
                  for benefits due to the Member's Total Disability) after the
                  Company receives the claim, unless special circumstances
                  require an extension of time for processing the claim. If such
                  an extension of time is required, written notice of the
                  extension shall be furnished to the claimant

                                       4


                  prior to the termination of the initial 90-day or 45-day
                  period, as applicable. In no event shall the extension exceed
                  a period of ninety (90) days (thirty (30) days with respect to
                  a claim for benefits due to the Member's Total Disability)
                  from the end of such initial period. With respect to a claim
                  for benefits due to the Member's Total Disability, an
                  additional extension of up to thirty (30) days beyond the
                  initial 30-day extension period may be required for processing
                  the claim. In such event, written notice of the extension
                  shall be furnished to the claimant within the initial 30-day
                  extension period. Any extension notice shall indicate the
                  special circumstances requiring the extension of time, the
                  date by which the Company expects to render the final
                  decision, the standards on which entitlement to benefits are
                  based, the unresolved issues that prevent a decision on the
                  claim and the additional information needed to resolve those
                  issues.

            (b)   CONTENTS OF NOTICE OF DENIAL

                  under a Plan, the Company shall provide to such claimant
                  written notice of the denial which shall set forth:

                        necessary for the claimant to perfect the claim and an
                        explanation of why such material or information is
                        necessary;

                  (iv)  an explanation of the Plan's claim review procedures,
                        and the time limits applicable to such procedures,

                        civil action under Section 502(a) of ERISA following an
                        adverse benefit determination on review;

                  (v)   in the case of a claim for benefits due to the Member's
                        Total Disability, if an internal rule, guideline,
                        protocol or other similar criterion is relied upon in
                        making the adverse determination, either the specific
                        rule, guideline, protocol or other similar criterion; or
                        a statement that such rule, guideline, protocol or other
                        similar criterion was relied upon in making the decision
                        and that a copy of such rule, guideline, protocol or
                        other similar criterion will be provided free of charge
                        upon request; and

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

            (c)   RIGHT TO REVIEW

                        documents, records, and other information submitted by

                        the initial benefit determination.

            (d)   APPLICATION FOR REVIEW

                  (i)   If a claimant wishes a review of the decision denying
                        his or her claim to benefits under the Plan, other than
                        a claim described in Section 8.17(d)(ii), he or she must
                        submit the written application to the Company within

                              whether the advice was relied upon in making the
                              determination to deny the claim.

                        Notwithstanding the foregoing, the health care

                  as applicable, shall submit its decision on the review in
                  writing to the claimant involved and to his representative, if
                  any, unless the Company or Appeals Fiduciary determines that
                  special circumstances (such as the need to hold a hearing)
                  require an extension of time, to a day no later than one
                  hundred twenty (120) days (ninety (90) days with respect to a
                  claim for benefits due to the Member's Total Disability) after
                  the date of receipt of the written application for review. If
                  the Company or Appeals Fiduciary determines that the extension
                  of time is required, the Company or Appeals Fiduciary shall
                  furnish to the claimant written notice of the extension before
                  the expiration of the initial sixty (60) day (forty-five (45)
                  days with respect to a claim for benefits due to the Member's
                  Total Disability) period. The extension notice shall indicate
                  the special circumstances requiring an extension of time and
                  the date by which the Company or Appeals Fiduciary expects to
                  render its decision on review. In the case of a decision
                  adverse to the claimant, the Company or Appeals Fiduciary
                  shall provide to the claimant written notice of the denial
                  which shall include:

                  (i)   the specific reasons for the decision;

                  (ii)  specific references to the pertinent provisions of the

                        benefits;

                  (iv)  an explanation of the Plan's claim review procedures,
                        and the time limits applicable to such procedures,
                        including a statement of the claimant's right to bring
                        an action under Section 502(a) of ERISA following the
                        denial of the claim upon review;

                  (v)   in the case of a claim for benefits due to the Member's
                        Total Disability, if an internal rule, guideline,
                        protocol or other similar criterion is relied upon in
                        making the adverse determination, either the specific
                        rule, guideline, protocol or other similar criterion; or
                        a statement that such rule, guideline, protocol or other

                        other similar criterion will be provided free of charge
                        upon request;

                  (vi)  in the case of a claim for benefits due to a Member's
                        Total Disability, if a denial of the claim is based on a

                  For purposes of this Section 8.17, the Appeals Fiduciary means
                  an individual or group of individuals appointed to review
                  appeals of claims for benefits payable due to the Member's
                  Total Disability. The Company shall appoint the Appeals
                  Fiduciary. The Appeals Fiduciary shall be required to review
                  claims for benefits payable due to the Member's Total
                  Disability that are initially denied by the Company and for
                  which the claimant requests a full and fair review pursuant to
                  this Section 8.17. The Appeals Fiduciary may not be the
                  individual who made the initial adverse determination with
                  respect to any claim he reviews and may not be a subordinate
                  of any individual who made the initial adverse determination.
                  The Appeals Fiduciary may be removed in the same manner in
                  which appointed or may resign at any time by written notice of
                  resignation to the Company. Upon such removal or resignation,
                  the Company shall appoint a successor."

      Except as specifically amended hereby, the Arrangement shall remain in
full force and effect prior to this First Amendment.

      IN WITNESS WHEREOF, the Company has caused this First Amendment to be
executed on the day and year first above written.
