Exhibit 99.01

                                AMENDMENT 1999-1
                          HILTON HOTELS RETIREMENT PLAN


                  WHEREAS, Hilton Hotels Corporation (the "Company") maintains
the Hilton Hotels Retirement Plan (the "Plan"); and

                  WHEREAS, the Company has the authority to amend the Plan on
behalf of itself and all Participating Affiliates (as defined in the Plan); and

                  WHEREAS, the Company and the Plan are defendants in a civil
action pending in the United States District Court for the District of Columbia
styled KIFAFI v. HILTON HOTELS RETIREMENT PLAN, ET. AL. (the "Action"); and

                  WHEREAS, the Plaintiff in such Action contends that the
formula under which benefits accrued under the Plan failed to satisfy the
requirements of Section 204(b)(1) of ERISA (commonly referred to as the
"anti-backloading" provision); and

                  WHEREAS, the Internal Revenue Service has previously
determined that the Plan satisfies the requirements of the Internal Revenue Code
applicable to a qualified plan, and such requirements include Code Section
411(b)(1), which is substantively identical to the anti-backloading provision of
ERISA; and

                  WHEREAS, the Company understands that the Plan satisfies the
anti-backloading provision without any amendment, but nonetheless intends to
amend the Plan to provide benefit increases to participants for the purpose of
eliminating any controversy regarding the propriety of the rate of benefit
accruals under the Plan.

                  NOW, THEREFORE, the Plan is hereby amended by adding the
following new Section 4.13:

                  4.13 BENEFIT INCREASE.

                  (a)      The benefit attributable to each Participant shall be
         the greater of the benefit determined without respect to this Section
         4.13 (the "Pre-Amendment Benefit"), or the benefit determined under
         this Section 4.13 (the "New Benefit"). The New Benefit attributable to
         the Participant shall be the benefit determined as if Section 4.1(a) of
         the Plan were the "Revised Section 4.1(a)," set forth in subsection (b)
         of this Section 4.13.




                  (b)      The "Revised Section 4.1(a)" is as follows:

                                   '(a)     A Participant may retire and
                  commence receiving his vested Normal Retirement Benefit on his
                  Normal Retirement Date. A Participant shall be 100% vested in
                  benefits under this Plan upon attainment of Normal Retirement
                  Age if the Participant is then an Employee. Except as
                  hereinafter provided, the amount of the monthly retirement
                  benefit payable each month for the life of a Participant,
                  commencing on his Normal Retirement Date and ending with the
                  benefit for the month during which his death occurs, which is
                  his Normal Retirement Benefit, shall be equal to the amount
                  determined by first multiplying (1) by (2), and then by
                  deducting (3), as follows:

                                             (1)     If the Participant had
                           completed 34 or more Years of Benefit Service as of
                           December 31, 1983, then (1) is the amount determined
                           by deducting (C) from the greater of (A) or (B), or,
                           if the Participant had not completed 34 or more Years
                           of Benefit Service as of December 31, 1983, then
                           (1) is the amount determined by deducting (C) from
                           (B):

                                             (A)     1-1/2% of the Participant's
                                    Average Monthly Compensation multiplied by
                                    his Potential Years of Benefit Service, but
                                    not more than 60% of such Average Monthly
                                    Compensation.

                                             (B)     The sum of: (i) 2% of the
                                    Participant's Average Monthly Compensation
                                    multiplied by his Potential Years of Benefit
                                    Service (up to a maximum of 25 years), plus
                                    (ii)1/2% of his Average Monthly Compensation
                                    multiplied by his Potential Years of Benefit
                                    Service in excess of 25, but the sum of (i)
                                    and (ii) shall not be more than 60% of such
                                    Average Monthly Compensation.

                                             (C)     Fifty percent (50%) of the
                                    "Potential Primary Social Security Benefit"
                                    of the Participant. The Potential Primary
                                    Social Security Benefit shall be calculated
                                    in the same manner as set forth in the
                                    definition of the Primary Social Security
                                    Benefit in Section 1.2, except that the last
                                    two sentences of the first paragraph of the
                                    definition shall be replaced with the
                                    following: "Such amount shall be determined
                                    on the basis of (i) the Participant's period
                                    of employment with the Participating
                                    Employers and (ii), if a Participant retires
                                    or otherwise incurs a Break in Employment
                                    prior to age 65, by assuming the Participant
                                    receives wages after such retirement or
                                    other Break in Employment until age 65 at
                                    the same rate the Participant received wages
                                    at the time of such retirement or other
                                    Break in Employment."

                                            (2)     A fraction, the numerator of
                           which is the Participant's years of Benefit Service,
                           and the denominator of which is the




                           Participant's Potential Years of Benefit Service.
                           For purposes of the Plan, "Potential Years of Benefit
                           Service" shall equal the greater of (i) the
                           Participant's actual Years of Benefit Service or (ii)
                           the Years of Benefit Service the Participant would
                           complete, if, after first becoming a Participant,
                           the Participant continued to serve as an active
                           employee and Participant in the Plan through the
                           Participant's Normal Retirement Date. Potential
                           Years of Benefit Service under this Section 4.13 are
                           calculated including all Years of Benefit Service
                           which would have been earned had Section 4.12 not
                           been adopted. The value of the fraction described in
                           this subsection shall not exceed one.

                                            (3)     The portion of the
                           Participant's Integrated Benefits not related to
                           Social Security benefits.'


                  (c)      The New Benefit shall be calculated with respect to
         all benefits attributable to each Participant (whether or not the
         Participant was an active employee as of the date the amendment adding
         Section 4.13 was adopted). The benefit attributable to a Participant
         may be payable to the Participant, or may be payable in whole or in
         part to an alternate payee under a qualified domestic relations order,
         a joint or contingent annuitant receiving benefits following the
         death of a Participant (including the surviving spouse under a
         Qualified Joint and Survivor Annuity), or a surviving spouse entitled
         to the Surviving Spouse Benefit under the Plan. Each such person
         (including each Participant), for whom the New Benefit is greater
         than the Pre-Amendment Benefit is referred to in this Section 4.13 as
         an "Affected Person." Notwithstanding the foregoing, any former
         Employee who was not vested under the Plan at the time of his or her
         termination of employment shall not be an Affected Person, and shall
         not be entitled to benefit under this Section 4.13.

                  (d)      Except for the benefit increases set forth in this
         Section 4.13, the benefit freeze enacted by adding Section 4.12 to the
         Plan stays in effect. Accordingly, in calculating the Pre-Amendment
         Benefit and the New Benefit, no Participant shall earn actual Years of
         Benefit Service for service following December 31, 1996, and any
         increases to Average Monthly Compensation based upon Compensation paid
         after December 31, 1996 shall be disregarded.

                  (e)      As soon as administratively feasible following the
         adoption of the amendment which added this Section 4.13 to the Plan,
         the Company shall cause the amendment to be submitted to the IRS with a
         request that the IRS determine that the Plan, as amended, satisfies the
         qualification requirements of Section 401(a) of the Code. It is
         understood that such qualification requirements include satisfaction of
         Code Section 411(b)(1) and the regulations issued thereunder. As soon
         as administratively feasible following the adoption of the amendment,
         the Company shall cause the New Benefits to be calculated. During
         the period that the New Benefits are being calculated and pending
         IRS approval, benefit payments shall temporarily continue at the
         Pre-Amendment Benefit level. As soon as administratively feasible
         following the later of the date the New Benefits have been calculated
         or the date the IRS issues a favorable determination letter concerning
         the amendment Plan, the payment amounts shall be revised as follows
         (the




         date on which an Affected Person's benefit payments are revised shall
         be the Affected Person's "New Benefit Date"):

                           (1)      If the Affected Person's Pre-Amendment
                  Benefit is greater than the Affected Person's New Benefit,
                  then no change to the Affected Person's Benefit shall be made.

                           (2)      If the Affected Person's New Benefit is
                  greater than the Pre-Amendment Benefit, but no payments had
                  been made to the Affected Person before the New Benefit Date,
                  then the New Benefit shall apply to all payments made to the
                  Affected Person.

                           (3)      If the Affected Person's New Benefit is
                  greater than the Pre-Amendment Benefit, and if payments
                  other than lump sum payments had been made under the
                  Pre-Amendment Benefit, then the New Benefit shall apply to all
                  payments made after the New Benefit Date, and in addition the
                  following retroactive payment shall be made. The retroactive
                  payment shall be a single lump sum payment equal to the sum of
                  the following amounts calculated with respect to each
                  Pre-Amendment Benefit payment made to the Affected Person
                  before the New Benefit Date: The amount determined by first
                  deducting (x) the monthly New Benefit from (y) the monthly New
                  Benefit, and then by increasing such remainder by (z) interest
                  on the remainder for the period from the date the
                  Pre-Amendment Benefit payment was made through the New Benefit
                  Date at an annual rate equal to the "applicable interest rate"
                  as described in section 417(e)(3) of the Code for the November
                  immediately preceding the Plan Year in which the retroactive
                  payment is made.

                           (4)      If the Affected Person's New Benefit is
                  greater than the Pre-Amendment Benefit, and payment of the
                  Pre-Amendment Benefit had been made as a lump sum, then an
                  additional lump sum payment shall be made.  The additional
                  lump sum payment shall be determined by first deducting (x)
                  the amount of the original lump sum payment, from (y) the
                  actuarial equivalent lump sum which would have been paid had
                  the New Benefit amount applied at the time the lump sum was
                  originally paid, and then by increasing such remainder by (z)
                  interest on the remainder for the period from the date the
                  original lump sum payment was made through the New Benefit
                  date at an annual rate equal to the "applicable interest rate"
                  as described in Section 417(e)(3) of the Code for the November
                  immediately preceding the Plan Year in which the retroactive
                  payment is made.

                           (5)      If any portion of the benefits earned with
                  respect to a Participant had been split between a Participant
                  and an alternate payee pursuant to a qualified domestic
                  relations order, then any increase in benefits (including any
                  retroactive payments) shall be divided proportionately
                  according to the portion of the Pre-Amendment Benefit which
                  had been assigned to the alternate payee.




                           (6)      If a Participant has died before the
                  Participant's New Benefit date, any additional benefits
                  payable on behalf of the Participant under this Section 4.13
                  shall be payable to the surviving beneficiary or
                  beneficiaries, if any, under the optional form of benefit, if
                  any, elected by the Participant, or, if there is no such
                  surviving beneficiary, to the Participant's surviving spouse
                  or, if there is no surviving beneficiary or surviving spouse,
                  to the Participant's estate.

                           (7)      The benefit payments hereunder shall be
                  appropriately adjusted under the actuarial factors set forth
                  in the plan, including but not limited to the factors
                  applicable to early retirement benefits, qualified joint and
                  survivor annuities, and other optional forms of benefits.

                  IN WITNESS WHEREOF, this Amendment 1999-1 is hereby adopted
this_____ day of ______, 1999.
