8.     Effective
as of March 28, 2005, Section 7.6 of the Plan shall be deleted in its entirety and replaced with the following:

"7.6Distributions on Termination of Employment for Reasons Other than Retirement. If a Member terminates employment for reasons
other than Retirement, and the value of his Vested Retirement Benefit does not exceed Five Thousand Dollars ($5,000), then distribution of such benefit shall be made in accordance with this
Section 7.6.



If
the present value of the Member's Vested Retirement Benefit is greater than One Thousand Dollars ($1,000), but does not exceed Five Thousand Dollars ($5,000) and the Member does not elect to either
have his Retirement Benefit paid in a direct rollover to a specified Eligible Retirement Plan as described in Code Section 402(c)(8)(B) or to receive the single sum payment in cash, then the
Administrator will pay the value of the Member's Retirement Benefit in a direct rollover to an individual retirement plan designated by the Administrator. However, notwithstanding the above, to the
extent required by Code Section 401(a)(31), effective for distributions occurring on or after March 28, 2005, amounts attributable to a Member's rollover account, if any, will be
included in determining whether a Member's Retirement Benefit is greater than One Thousand Dollars ($1,000) for purposes of the automatic rollover rules of this Section 7.6. If the value of the
Member's Retirement Benefit is not greater than One Thousand Dollars ($1,000), then it shall be automatically distributed to the Member in a single lump sum payment (unless the Member elects a direct
rollover as specified above).

---



Pursuant
to Code Section 401(a)(31)(B), the above paragraph concerning automatic IRA rollovers shall not apply to distributions to beneficiaries or alternate payees.

A
Member's Credited Service under the Plan shall be disregarded following the single sum payment of the Member's Retirement Benefit under this Section 7.6(a) if the Member subsequently returns
to employment with the Employer. Because a Member who receives a single sum payment of his Retirement Benefit under this Section 7.6(a) shall receive the full present value thereof, such Member
shall not be entitled to repay such distribution upon his subsequent re-employment by the Employer as provided under Treas. Reg. § 1.411(a)-7(d)(4).



9.     Effective
as of March 28, 2005, Section 16.2 of the Plan shall be deleted in its entirety and replaced with the following:

"16.2Unclaimed Benefit Procedure. Except to the extent required by ERISA, neither the Trustee nor the Committee shall be obliged
to search for, or ascertain the whereabouts of, any Member or Beneficiary. The Administrator, by certified or registered mail addressed to his last known address of record with
the Administrator or the Employer, shall notify any Member or Beneficiary that he is entitled to a distribution under this Plan, and the notice shall quote the provisions of this Section (to the
extent possible, the Administrator will also check any other plan of the Employer to ensure it has the most up-to-date information with respect to the Member's address). If the Member or Beneficiary
fails to claim his benefits or make his whereabouts known in writing to the Administrator, and the Administrator is otherwise unable to locate the Member or Beneficiary after reasonable due diligence,
the Administrator shall notify the Social Security Administration, IRS (or other appropriate agency) of the Member's (or Beneficiary's) failure to claim the distribution to which he is entitled. The
Administrator shall request the Social Security Administration, IRS (or other appropriate agency) to notify the Member (or Beneficiary) in accordance with the procedures it has established for such
purpose. If the Social Security Administration, IRS (or other appropriate agency) cannot locate the Member (or Beneficiary), (i) except as provided below, the benefit shall be treated as a
Forfeiture hereunder, provided that the benefit shall be reinstated in the event that the Member or Beneficiary ever makes a claim therefor, and (ii) if the Member's Vested Retirement Benefit
is greater than One Thousand Dollars ($1,000), but does not exceed Five Thousand Dollars ($5,000), then that amount will be rolled-over to an Administrator-designated individual retirement account
pursuant to Section 7.6 as if an employee election had not been made. Any payment made pursuant to the power herein conferred upon the Administrator shall operate as a complete discharge of all
obligations of the Employer, Trustee, and the Administrator, to the extent of the distributions so made."

IN WITNESS WHEREOF, the Company has caused this Fifth Amendment to The Sabre Inc. Legacy Pension Plan to be executed on date listed
below, but to be effective as stated above.
