it will not take or fail to take, or permit any Affiliate to take or fail to
take, any action where such action or failure to act would be inconsistent with
any material, information, covenant or representation in the Sabre
Representation Letter, unless Sabre obtains a Supplemental Ruling (reasonably
acceptable to AMR) that such action will not affect the treatment of the Spinoff
as tax-free under Section 355 of the Code.

          3.02 LIABILITY FOR UNDERTAKING CERTAIN ACTIONS.  Sabre and each Sabre
Affiliate shall be responsible for one hundred percent (100%) of any Spinoff

Taxes).  Sabre and each Sabre Affiliate shall jointly and severally indemnify,

Ruling (reasonably acceptable to AMR) that such agreement will not affect the
treatment of the Spinoff as tax-free under Section 355 of the Code and other
relevant provisions; or (b) obtain an opinion (reasonably acceptable to AMR) of
nationally recognized tax counsel that such agreement will not affect the
treatment of the Spinoff as tax-free under Section 355 of the Code and other
relevant provisions.  Any such opinion shall be entitled to make reasonable
assumptions as to the facts and rely without independent inquiry on
representations by Sabre, AMR and their Affiliates, and shall explain tax
counsel's legal reasoning in reaching its conclusion.  Notwithstanding anything
in Section 4.01 to the contrary, Sabre shall not be required to obtain either a
Supplemental Ruling or an opinion prior to entering into any agreement to issue
stock (or options or other rights to acquire its stock), to the extent the
cumulative effect of all relevant transactions does not result, for purposes of
Section 355(e) of the Code, in one or more persons acquiring, during the four
year period beginning two years prior to the Effective Date, directly or
indirectly Sabre stock possessing at least 35 percent of the total combined
voting power or all classes of stock entitled to vote or at least 35 percent of

of Sabre, any Sabre Affiliate, or Travelocity Holdings, Inc. by any person or
persons, whether or not with the consent of or against the wishes of Sabre or

V.   INDEMNIFICATION AND CONTROL OF LITIGATION

          5.01.     INDEMNIFICATION.  Sabre and each Sabre Affiliate shall
jointly and severally indemnify, on an After Tax Basis, AMR, each AMR Affiliate
and their respective directors, officers and employees and hold them harmless
from and against any such Spinoff Restructuring Taxes and related Losses to the
extent provided in Articles II, III, and IV of this Agreement.  AMR and each AMR
Affiliate shall jointly and severally indemnify, on an After Tax Basis, Sabre
and each Sabre Affiliate and their respective directors, officers and employees
and hold them harmless from Spinoff Restructuring Taxes and related Losses to
the extent not assumed or indemnified by Sabre under this Agreement.

          5.02.     TREATMENT OF PAYMENTS; TAX GROSS UP.  To the extent
permitted by applicable law, the parties agree that any payment made pursuant to
this Agreement shall be treated as a capital contribution or dividend
distribution, as the case may be, immediately prior to the Effective Date, for
all Tax purposes, and accordingly, as not includible in the taxable income of
the recipient.  If notwithstanding the manner in which such payments were
reported, there is an adjustment to the Tax liability of any Indemnitee as a
result of its receipt of a payment pursuant to this Agreement, such payment
shall be made on an After Tax Basis.  Sabre or AMR will pay any amount due and
payable pursuant to this Agreement on or before the 15th day following the
earlier of written agreement or final determination that such amount is due and
payable.  All payments shall be made by wire transfer to the bank account
designated by the Indemnitee for such purposes, and on the date of such wire
transfer the Indemnitor shall give the Indemnitee notice of the transfer.

          5.03.     CONTROL OF LITIGATION.  Following the Effective Date, AMR
shall, in its sole discretion, control and direct the conduct of any audit or
inquiry or any administrative or judicial appeal or other proceeding regarding
Spinoff Restructuring Taxes.  Further, AMR shall have exclusive authority and
control over the investigation, prosecution, defense, and appeal of all Tax
litigation relating to or arising in connection with the Spinoff, and may settle
or compromise, or consent to the entry of any judgment with respect to any such
litigation, without the consent of Sabre.  However, AMR and Sabre shall jointly
control and direct the conduct of any audit or inquiry or any administrative or
judicial appeal or other proceeding related to or arising out of representations
10, 11 or 14 of the Sabre Representation Letter, and neither AMR nor Sabre shall
settle or compromise, or consent to the entry of any judgment with respect to
any such litigation without the prior written consent of the other.
Notwithstanding the foregoing provisions of this Section 5.03:  (i) AMR shall
promptly notify Sabre of any action or threatened action by any Tax Authority
which could give rise to liability or indemnification by Sabre under this
agreement; (ii) AMR shall allow a representative of Sabre to participate in any
meetings with such Tax Authority and shall allow Sabre reasonable opportunity to
review and comment on any submission by AMR to such Tax Authority; and (iii) in
the event that a Tax Authority raises a position which, if sustained, would
result in a Tax for which Sabre would bear one hundred percent (100%) of the
liability (as Indemnitor or otherwise) for such issue, and Sabre acknowledges in
writing its agreement that it would be liable for such Tax and provides evidence
(reasonably satisfactory to AMR) demonstrating its ability to pay such Tax, AMR
shall afford Sabre the opportunity to control the contest of such assertion of
Tax, at its own expense, in such manner as Sabre shall reasonably direct, and
Sabre shall provide AMR the opportunity to reviw


                                          6

<PAGE>

and comment upon any materials produced by Sabre pursuant to such contest prior
to their submission and shall permit AMR to participate in any meetings with any
Tax Authority in connection therewith.

          5.04.     REPORTING OF SPINOFF.  (a)  The Tax treatment reported on
any Tax Return of Tax items relating to the Spinoff shall be consistent with the
treatment of such item in the Ruling.  To the extent there is a Tax item
relating to the Spinoff which is not covered by the Ruling, the parties shall
agree on the Tax treatment of any such Tax item reported on any Tax Return.  Any
dispute regarding the proper Tax treatment of any such item shall be resolved as
determined by AMR, provided that AMR obtains an opinion (reasonably acceptable
to Sabre) of nationally recognized tax counsel in support of such treatment.

          (b)  AMR shall provide each shareholder that receives stock of Sabre
pursuant to the Spinoff with the information necessary for such shareholder to
comply with the requirements of Section 355 of the Code and the Treasury
Regulations thereunder with respect to statements that such shareholders must
file with their Tax Returns demonstrating the applicability of Section 355 of
the Code to the Spinoff.


VI.  TAX BENEFITS

          6.01.     If AMR (or an AMR Affiliate) or Sabre (or a Sabre Affiliate)
receives any Tax Benefit (e.g., under Section 336 of the Code) with respect to
any Taxes for which the other party is liable hereunder, the party receiving
such Tax Benefit shall make a payment to the party who is liable for such Taxes
hereunder within 30 days following receipt of the Tax Benefit in an amount equal

payment).

connection with preparation of Tax Returns, Tax Contests, and other matters
related to Taxes under the provisions of this Agreement.

          7.15.     RETENTION OF TAX RECORDS. Each party shall preserve and keep
all Tax records (e.g., Tax Returns, workpapers, and documents related to any Tax
Proceeding) relating to the Spinoff and Spinoff Restructuring Transactions, for
so long as the contents thereof may become material in the administration of any
matter under the Code or other applicable Tax law, but in any event until the
later of (i) the expiration of any applicable statutes of limitation, and (ii)
seven years after the Effective Date. If, prior to the expiration of the
applicable statute of limitation and such seven-year period, a party reasonably
determines that any Tax records which it is required to preserve and keep under
this Section 7.15 are no longer material in the administration of any matter
under the Code or other applicable Tax law, such party may dispose


                                          9

<PAGE>

this Agreement.

AMR Corporation
4333 Amon Carter Boulevard
Fort Worth, Texas 76155

          Re:       Agreement on Spinoff Taxes between AMR Corporation and Sabre
                    Holdings Corporation dated as of March 15, 2000 (the
                    "Agreement on Spinoff Taxes")

Ladies and Gentlemen:

          This representation letter is furnished to you in connection with the
Application for Ruling Under Section 355 filed by AMR Corporation, dated October
8, 1999 (the "Application for Ruling"), and the Agreement on Spinoff Taxes.  All
capitalized terms not otherwise defined herein have the meanings ascribed to
them in the Application for Ruling and the Agreement on Spinoff Taxes.  The
following representations are being made available to you for the purposes of
the Application for Ruling and the Agreement on Spinoff Taxes, and we understand
that you will be relying on such representations.  As of the date hereof, the
undersigned, a duly authorized officer of Sabre and acting as such, hereby
certifies that the facts set forth below are true, correct and complete:

1.   The indebtedness, if any, owed by Sabre Holdco to AMR after the
     Distribution will not constitute stock or securities.

2.   Immediately after the Distribution, at least 90% of the fair market value
     of the gross assets of Sabre Holdco will consist of the stock and
     securities of controlled corporations that are directly or indirectly
     engaged in the active conduct of a trade or business as defined in Section
     355(b)(2).

3.   The five years of financial information submitted on behalf of Sabre Opco
     are representative of its present operation, and there has been no
     substantial operational change (other than Sabre Opco's anticipated
     transaction with Preview Travel) since the date of the last financial
     statement submitted with the Application for Rulings.

4.   Following the Distribution, Sabre Opco will continue the active conduct of
     its business, independently and with its separate employees.

5.   Immediately after the Distribution, the gross assets of Sabre Opco used in
     the conduct of its business will have a fair market value equal to or
     greater than 5% of the total fair market value of the gross assets of Sabre
     Opco.


<PAGE>

6.   The distribution of Sabre Holdco stock is motivated, from Sabre Holdco's
     perspective, by the corporate business purpose of eliminating the
     disincentives of other airlines to engage Sabre to perform information
     technology services.

7.   The management of Sabre, to its best knowledge, is not aware of any plan or
     intention on the part of any particular shareholder or security holder of
     AMR or Sabre Holdco to sell, exchange, transfer by gift, or otherwise
     dispose of any stock in, or securities of, Sabre Holdco after the
     Distribution.

8.   There is no plan or intention by Sabre Holdco, directly or through any
     subsidiary corporation, to purchase any of its outstanding stock after the
     Distribution, other than through stock purchases meeting the requirements
     of Section 4.05(1)(b) of Rev. Proc. 96-30.

9.   There is no plan or intention to liquidate Sabre Holdco or merge Sabre
     Holdco with any other corporation, or sell or otherwise dispose of the
     assets of Sabre Holdco after the Distribution, except in the ordinary
     course of business.

10.  Except for accounts payable that arise in connection with continuing
     services between the AMR Group and Sabre, no intercorporate debt will exist
     between the AMR Group and Sabre at the time of, or subsequent to, the
     Distribution of the Sabre Holdco stock.

11.  Payments made in connection with all continuing transactions between the
     AMR Group and Sabre will be for fair market value based on terms and
     conditions arrived at by the parties bargaining at arm's length.

12.  Sabre is not an investment company as defined in Section 368(a)(2)(F)(iii)
     and (iv).

13.  The Distribution is not part of a Sabre plan or series of related
     transactions (within the meaning of section 355(e)) pursuant to which one
     or more persons will acquire directly or indirectly stock possessing 50% or
     more of the total combined voting power of all classes of stock of Sabre
     Holdco or stock possessing 50% or more of the total value of all classes of
     stock of Sabre Holdco.

14.  For federal income tax purposes, the cash dividend in the approximate
     amount of [$650]$675 million which will be paid by Sabre to AMR in
     connection with the Spinoff (the "Cash Dividend") will qualify as an
     intercompany distribution within the meaning of Section 1.1502-13(f) of the
     Treasury Regulations.

          All of the foregoing certifications are true, correct and complete on
the date hereof.

                                             Very truly yours,

                                             Sabre Holdings Corporation

                                             By:_________________
                                             Name: Jeffery M. Jackson

                                             Chief Financial Officer

Tax Items attributable to transactions occurring between any SABRE Company, on
the one hand, and any AMR Company, on the other, during any Post-Effective Date

respect of which a SABRE Pro Forma Consolidated Return is prepared, SABRE shall
pay to AMR an amount equal to the excess, if any, of (i) all federal income
taxes shown as due on the SABRE Pro Forma Consolidated Return (plus the amount,
if any, of any interest or penalties that would have been payable by the SABRE
Pro Forma Affiliated Group in respect of underpayments of estimated taxes if it
actually were filing the SABRE Pro Forma Consolidated Return for such taxable
period and made estimated tax payments equal to the payments SABRE made to AMR
in respect of estimated federal income taxes for such taxable period pursuant to
this Section 3.02) federal income taxes for such taxable period pursuant to this
Section 3.02), over (ii) the total of such estimated tax payments.  If, pursuant
to Section 3.01, AMR permits SABRE to submit the SABRE Pro Forma Consolidated
Return after such date, a reasonable estimate of such amount shall be paid on or
before such date and the balance, if any, due on the SABRE Pro Forma
Consolidated Return shall be paid on the date that the SABRE Pro Forma
Consolidated Return is required to be submitted.  If (A) the total amount of all
payments of federal income taxes by SABRE to AMR pursuant to this Section 3.02
for the taxable period exceeds (B) the taxes shown as due on the SABRE Pro Forma
Consolidated Return prepared with respect to such taxable period, the amount of
such excess shall (1) be credited to the account of SABRE and shall reduce the
amount of any future payments otherwise payable by SABRE and shall reduce the
amount of any future payments otherwise payable by SABRE to AMR pursuant to
Section 3.02, or (2) if requested in writing by SABRE, be repaid by AMR to SABRE
either (X) within 15 days after the filing of the AMR Consolidated Return for
the tax period with respect to which such excess was paid or (Y) if, and to the
extent that, the AMR Consolidated Return for such tax period reflects an
overpayment of estimated federal income taxes by the AMR Affiliated Group,
within 15 days after AMR's receipt of a refund of such over-payment.

          3.03   REFUNDS IN RESPECT OF CARRYBACKS.  if, for any Post-Effective
Date Period, (i) a SABRE Pro Forma Consolidated Return reflects a consolidated
net operating loss, consolidated net capital loss, or consolidated unused tax
credit and (ii) under the Code and


                                          7

<PAGE>

regulations promulgated thereunder such consolidated loss or unused credit could
have been carried back to a prior Post-Effective Date Period of the SABRE Pro
Forma Affiliated Group, SABRE shall prepare and submit to AMR an amended SABRE
Pro Forma Consolidated Return, prepared as provided in Section 3.01 of this
Agreement, for each Post-Effective Date Period to which such carryback would be
permitted.  If the amount by which the aggregate amounts paid by SABRE to AMR
under Section 3.02 of this Agreement in respect of the federal income tax
liability of the SABRE Pro Forma Affiliated Group for such Post-Effective Date
Period exceeds the amount of such liability as reflected on the amended SABRE
Pro Forma Consolidated Return, the amount of such excess shall be (1) credited
to the account of SABRE and shall reduce the amount of any future payments
otherwise payable by SABRA to AMR pursuant to section 3.02, or (2) if requested
in writing by SABRE, refunded to SABRA by AMR with 45 days after its receipt of
the amended SABRE Pro Forma Consolidated Return.  All calculations of deemed
refunds pursuant to this Section 3.03 shall include interest computed as if
SABRE had filed a claim for refund or an application for a tentative carryback
adjustment pursuant to Code Section 6411(a) on the date on which it provides AMR
with the amended SABRE Pro Forma Consolidated Return.  Determinations under this
under this Section 3.03 shall be made as if the SABRE Pro Forma Affiliated Group
were not permitted to carryback any consolidated loss or unused credit from a
Post-Effective Date Period to a taxable period or portion thereof ending before
the Effective Date.  AMR shall be entitled to retain, or receive immediate
payment from any SABRE Company of any refund or credit with respect to federal
income tax liability that actually results from such a carryback.

          3.04   LIABILITY FOR PRE-EFFECTIVE DATE PERIODS AND SPIN-OFF
TRANSACTION.

ARM shall be liable for, and shall indemnify and hold harmless the SABRE
Companies for, (1) any federal Income Taxes imposed on or incurred by any SABRE
Company for any Pre-Effective Date Period, and (2) any federal Income Taxes that
are attributable to the Spin-off Transaction.

          3.05.  PAYMENTS IN THE EVENT OF DECONSOLIDATION.

          (a)    STATEMENT OF SABRE EXCESS TAX ATTRIBUTES.  As soon as practical
following the filing by the AMR Affiliated Group of its consolidated federal
income tax return for the year which includes the Deconsolidation Date, AMR will
provide to SABRE its estimate of the amount of any SABRE Excess Tax Attributes.
No warranty as to the existence or availability of such attributes will be given
or implied.  AMR will inform SABRE promptly of an adjustment to such attributes
that it determines to be appropriate in connection with the filing of the AMR
Consolidated Group's Tax Returns or which may result from any audit or other
proceeding.


                                          8

          (b)    SABRE PAYMENTS.  SABRE shall make payments to AMR under this
Section 3.05(b) if, for any Post-Consolidation Period, (i) the actual federal
income tax liability of the SABRE Companies is reduced below the federal income
tax liability that would have been imposed on the SABRE Companies if (A) the
SABRE Pro Forma Affiliated Group actually had been deconsolidated from the AMR
Affiliated Group as of the Effective Date and had filed the SABRE Pro Forma
Consolidated Returns for all Post-Effective Date Periods (other than a
Post-Consolidation Period), and (B) the assumptions set forth in Section 3.01 of
this Agreement (other than clauses (vi) and (vii) thereof) actually applied, or
(ii) the federal income tax liability of the AMR Affiliated Group is increased
because any SABRE Excess Tax Attribute is not available for use by the AMR
Affiliated Group in that period.  The amount of any payment by SABRE under this
Section 3.05(b) shall equal the excess of (X) the sum of (i) the amount of such
reduction or increase, as the case may be, in federal income tax liability plus
(ii) the amount of all prior reductions or increases taken into account pursuant
to this Section 3.05, over (Y) the amount of any payments previously made by
SABRE under this Section 3.05(b) in respect of any SABRE Excess Tax Attribute,
PROVIDED, HOWEVER, that the aggregate amount paid by SABRE to AMR pursuant to
this Section 3.05(b) shall not exceed the product of (l) the estimated amount of
SABRE Excess Tax Attributes provided by AMR to SABRE pursuant to Section 3.05(a)
above (as adjusted from time to time pursuant to such section), times (m) the
maximum federal income tax rate applicable to corporations as in effect from
time to time as each payment has been made pursuant to this Section 3.05(b).
SABRE shall make any payment required to be made under this Section 3.05(b)
within 15 days of, as the case may be, the filing of the applicable return or
amended return, or the receipt of the applicable Final Determination, for the
Post-Consolidation Period by SABRE or AMR (or, in the case of an increase in
liability of the AMR Affiliated Group, any later date on which SABRE receives
written notice from AMR).

          (c)    AMR PAYMENTS.  AMR shall make a payment to SABRE under this
Section 3.05(c) if, for any Post-Consolidation Period, the actual federal income
tax liability of the SABRE Companies is increased above the federal income tax
liability that would have been imposed on the SABRE Companies if (i) the SABRE
Pro Forma Affiliated Group actually had been deconsolidated from the AMR
Affiliated Group as of the Effective Date and had filed the SABRE Pro Forma
Consolidated Returns for all Post-Effective Date Periods (other than a
Post-Consolidation Period), and (ii) the assumptions set forth in Section 3.01
of this Agreement (other than clauses (vi) and (vii) thereof) actually applied.
The amount of any payment by AMR under this Section 3.05(c) shall equal the
amount of such increase.  In addition, AMR shall make a payment to SABRE under
this Section 3.05(c) equal to the amount of any unused SABRE Pro Forma R&E Tax
Credit Carryovers that are not available for use by the SABRE


                                          9

<PAGE>

Pro Forma Affiliated Group in a Post-Consolidation Period.  AMR shall make any
payment required to be made under this Section 3.05(c) within 15 days of, as the
case may be, the filing of the applicable return or amended return, or the
receipt of the applicable Final Determination, for the Post-Consolidation Period
by SABRE (or any later date on which AMR receives written notice from SABRE).

IV.  PAYMENTS IN RESPECT OF OTHER TAXES

          4.01.  STATE OR LOCAL INCOME TAXES REPORTED ON A CONSOLIDATED RETURN.

          (a)    PRE-EFFECTIVE DATE PERIODS.  AMR shall be liable for, and shall
indemnify and hold harmless the SABRE Companies for, (i) any state or local
Taxes on, or measured by, net income that are incurred by, imposed on or
attributable to any SABRE Company for any Pre-Effective Date Period (other than
such Taxes reported or required to be reported (whether or not actually
reported) in a Separate Return filed exclusively for such SABRE Company) and
(ii) any state or local income Taxes on, or measured by, net income that are
attributable to the Spin-off Transaction.

the sharing of Tax liability shall be determined under rules equivalent to the
provisions of Article III (including, without limitation, equivalent rules as to
the preparation of pro forma state or local tax returns for the applicable SABRE
Pro Forma Affiliated Group, the making of payments by SABRE with respect to
liability reported thereon, refunds in respect of carrybacks, and adjustments in
the event of Deconsolidation), whether or not for federal income tax purposes
the applicable SABRE Pro Forma Affiliated Group is included in the AMR
Consolidated Return.

          4.02.  FOREIGN TAXES.  AMR shall be liable for, and shall indemnify
and hold harmless the SABRE Companies for, (i) any Foreign Taxes which are
creditable under the Code (other than deemed paid Taxes under Code section 902
that have not been taken into account prior to the Spin-off Transaction)
incurred by, imposed on or attributable to any SABRE Company for any
Pre-Effective Date Periods, (ii) any such Foreign Taxes for any Post-Effective
Date Period that are attributable to the Spin-off Transaction, and (iii) all
other Foreign Taxes incurred by, imposed on or attributable to any SABRE Company
for any Pre-Effective Date Periods to the extent such liabilities do not exceed
the amount of any AMR reserves set aside therefor as of the Effective Date.
SABRE shall be liable for, and shall indemnify and hold harmless the AMR
Companies for, all other Foreign Taxes incurred by, imposed on or attributable
to any SABRE Company to the extent such liabilities exceed the amount of any AMR
reserves set aside therefor as of the Effective Date.

<PAGE>

          4.03.  OTHER TAXES.  Except as otherwise expressly provided in this
Agreement, SABRE shall be liable for all other Taxes incurred by, imposed on or
attributable to (i) any SABRE Company or (ii) any AMR Company with respect to

pursuant to the Spin-off Transaction (including, without limitation, any sales,
use, value-added or other similar transfer Taxes attributable to the transfer of
properties and assets by any AMR Company to any SABRE Company pursuant to the
Spin-off Transaction) and shall indemnify and hold harmless the AMR Companies
for any such liabilities imposed on them to the extent such liabilities exceed
the amount of any AMR reserves set aside therefor as of the Effective Date;
PROVIDED, HOWEVER, that AMR shall be liable for the Taxes described in this
Section 4.03 to the extent of its reserves set aside therefor.

          4.04.  ENVIRONMENTAL TAX; NEW TAXES.  In the case of the Tax imposed
under section 59A of the Code and any other federal, state, local, or Foreign
tax reported on a Consolidated Return for any Post-Effective Date Period
pursuant to Section 2.01 of this Agreement, the sharing of Tax liability shall
be determined under rules equivalent to the rules of Article III (including,
without limitation, equivalent rules as to the preparation of Pro forma returns
for the applicable SABRE Pro Forma Consolidated Group, the making of payments by
SABRE with respect to liability reported thereon, refunds in respect of
carrybacks and adjustments in the event of Deconsolidation), whether or not for
federal income tax purposes the applicable SABRE Pro Forma Affiliated Group is
included in the AMR Consolidated Return.

          4.05.  CAP AND ALLOCATION OF CERTAIN LIABILITIES.  The liability of
SABRE or AMR to make indemnity payments under Section 4.02 or 4.03 shall be

sales, use, value-added or other similar transfer Taxes attributable to the
transfer of properties and assets by any AMR Company to any SABRE Company
pursuant to the Spin-off Transaction (the "Spin-off Transfer Taxes")) of SABRE
or any SABRE Company for any Pre-Effective Date Period, SABRE's indemnity
obligation to AMR shall be limited to an aggregate amount of $4,000,000 and AMR

imposed directly on them by a taxing authority to the extent that the sum of
such liability plus SABRE's previous indemnity payments to AMR exceeds
$4,000,000, and (ii) with respect to Spin-off Transfer Taxes, SABRE's indemnity
obligation to AMR shall be limited to an aggregate amount of $2,000,000 and AMR

V.   SUBSEQUENT ADJUSTMENTS OF TAX LIABILITY

          5.01.  POST-EFFECTIVE DATE TAX PERIODS.  If any Final Determination
results in an adjustment to any Tax Item of any SABRE Company for any
Post-Effective Date Period or any Tax Item of any AMR Company for any
Post-Consolidation Period, the liability of SABRE to make payments to AMR under
Section 3.02, 3.05, 4.01, or 4.04, or the liability of AMR to make payments to
SABRE under Section 3.03, 3.05, 4.01, or 4.04, for all Post-Effective Date
Periods shall be redetermined to reflect such adjustment.  SABRE shall pay to
AMR (i) any excess of the aggregate amount of SABRE's net liability to AMR under
such Sections, as calculated pursuant to such redetermination, over the net
amount previously paid by SABRE in respect of such liability under such
Sections, plus (a) interest with respect to the amount determined in clause (i),
plus (b) the amount of any penalties, additions to tax, or expenses which are
paid by any AMR Company with respect to such adjustment (including, without
limitation, any reasonable out-of-pocket costs incurred by the AMR Companies in
connection with the assessment or collection thereof), reduced by (ii) any
amount paid directly by a SABRE Company to any government or taxing authority to
satisfy the increased tax liability taken into account in computing such
payment.  AMR shall pay to SABRE (A) any excess of the net amount previously
paid by SABRE to AMR in respect of SABRE's liability under such Sections over
the aggregate amount of SABRE's net liability under such Sections, calculated
pursuant to such redetermination, plus (B) the amount of any interest received
by an AMR Company from any government or taxing authority with respect to such
adjustment, reduced by (C) the amount of any refund of Tax received directly
from any government or taxing authority by any SABRE Company with respect to
such adjustment.  Any amount payable pursuant to this Section 5.01 shall be paid
within 15 days after the date of the Final Determination giving rise to such
payment.

<PAGE>

          5.02.  PRE-EFFECTIVE DATE ADJUSTMENTS.

          (a)    PAYMENT FOR INCREASE IN TAX LIABILITIES.  If, for any
Pre-Effective Date Period, any Final Determination results in an adjustment to
any Tax Item (i) of any SABRE Company or (ii) relating to any business or assets
transferred by an AMR Company to any SABRE Company pursuant to the Spin-off
Transaction, causing an increase in any Tax for which SABRE is liable pursuant
to Section 2.02, 4.02 or 4.03 hereof, subject to all limitations on such
liability (including, without limitation, Section 4.05), SABRE shall pay to AMR
an amount equal to (A) such increase in Tax liability plus (B) any expenses
which are paid by any AMR Company with respect to such adjustment (including,
without limitation, any reasonable out-of-pocket costs incurred by the AMR
Companies in connection with the assessment or collection thereof), reduced by
(C) any amount paid directly by a SABRE Company to any government or taxing
authority to satisfy such increased Tax liability.  SABRE shall make any such
payment within 15 days of AMR's payment of the increase in liability.  AMR shall
pay to SABRE an amount equal to any refund of Taxes (including any interest with
respect thereto) for the AMR Affiliated Group or any AMR Company for any
Pre-Effective Date Period or portion thereof that SABRE is responsible for under
the terms of this Agreement and that is received by any AMR Company on or after
the Effective Date and that is attributable to an adjustment of any Tax Item
(i) of any SABRE Company or (ii) relating to any business or assets transferred
by an AMR Company to any SABRE Company pursuant to the Spin-off Transaction.
AMR shall make any such payment within 15 days of the receipt of the refund by
AMR or another AMR Company.

          (b)    PAYMENT FOR CERTAIN TAX BENEFITS.  If the income Tax liability
of any AMR Company, or any SABRE Company with respect to any such income Taxes
AMR is responsible for under the terms of this Agreement, is increased for any
Pre-Effective Date Period and the particular item that produced such increase
results, directly or indirectly, in a Tax Benefit of any SABRE Company for any
Post-Effective Date Period, SABRE shall pay AMR the amount of any actual
reduction in Taxes resulting from such Tax Benefit within 15 days after the
later of (i) the due date (without regard to waivers or extensions) of the Tax
Return for the taxable period during which the Tax Benefit was utilized or
(ii) the date notice is given by AMR to SABRE with respect to such payment.


                                          13

<PAGE>

          5.03.  CARRYBACKS OF POST-CONSOLIDATION PERIOD TAX BENEFITS.

          (a)    If a SABRE Company incurs a Tax Benefit during any
Post-Consolidation Period which either (i) is required under applicable law to
be carried back to any taxable period ending on or before the Deconsolidation
Date or (ii) SABRE properly elects to carry back to such earlier taxable period,
then AMR will pay to SABRE the amount of any actual reduction in tax liability
resulting from the carryback of such Tax Benefit (to the extent that SABRE or
any SABRE Company does not receive such amount directly from the appropriate
taxing authority).  The amount of such reduction shall be equal to the excess of
(A) the amount of any Taxes that would have been payable by the AMR Affiliated
Group in the absence of such carryback, over (B) the amount of such Taxes
actually payable by the AMR Affiliated Group including such carryback.  Such
payment shall be made within thirty (30) days of the receipt by AMR or any AMR
Company of the Tax Benefit of any such reduction.  At SABRE's request and
expense, AMR shall undertake those actions reasonably necessary to enable SABRE
to carry back a Tax Benefit incurred in a Post-Consolidation Period.

          (b)    If, subsequent to the payment by AMR to SABRE of any amount
referred to in Section 5.03(a) above, there shall be (i) a Final Determination
under applicable law of a Tax deficiency of the AMR Affiliated Group as a result
of which the AMR Affiliated Group does not get the benefit of the carryback, or
(ii) a Final Determination resulting from an audit of SABRE or any SABRE Company
(or any successor thereto) which results in a reduction of any Tax Benefit so
carried back, SABRE shall repay AMR, within thirty (30) days of such Final
Determination, the amount which would not have been payable to SABRE pursuant to
Section 5.03(a) above had the amount of the payment been determined by taking to
account such event.

VI.  ADMINISTRATIVE PROVISIONS

          6.01.  CONTESTS.

          (a)    NOTICE.  SABRE shall provide AMR written notice of any claim,
or of the commencement of any audit or proceeding, together with copies of all
correspondence, notices or other documents relating thereto, which may result in
a Final Determination which would adjust any Tax Item of a SABRE Company
reportable on any Consolidated Return.  Whenever as a result of examination or
audit by a governmental authority AMR becomes aware of the existence of a
material issue involving a Tax Item of any SABRE Company which may result in a
Final Determination with respect to a Consolidated Return, AMR shall promptly
give notice to SABRE of the existence of such issue.

          (b)    CONTROL OF CONSOLIDATED RETURN CONTROVERSIES.  AMR shall, in
its sole discretion, control and direct the conduct of any audit or inquiry or
any administrative or



                                          14

<PAGE>

judicial appeal or other proceeding regarding any Consolidated Return or the
payment of any Tax by the AMR Affiliated Group or any entity not required to be
reported on a SABRE Separate Return.  Each SABRE Company shall provide AMR with
powers of attorney or other appropriate documents which will enable AMR to
conduct any such proceeding.  AMR may, in its sole discretion, agree to pay,
settle, compromise, or concede any such claim or issue arising with respect to
any proceeding which it controls pursuant to this Section 6.01(b); PROVIDED,
HOWEVER, that SABRE may prevent a proposed settlement or compromise of any Tax
Item of a SABRE Company arising in a Consolidated Return if (i) it provides AMR
with an opinion of tax counsel reasonably acceptable to AMR that SABRE's
position is more likely than not to prevail in litigation and (ii) it agrees to
indemnify AMR for any costs associated with contesting such issue.

          (c)    EXPENSES RELATED TO CONSOLIDATED RETURN CONTROVERSIES.  SABRE
shall promptly reimburse AMR for all expenses (including, without limitation,
legal and accounting fees) incurred by AMR in the course of proceedings
described in Section 6.01(b) of this Agreement to the extent such expenses are
reasonably attributable to Tax Items of any SABRE Company.

          6.02.  COOPERATION AND EXCHANGE OF INFORMATION.

          (a)    IN GENERAL.  AMR and SABRE will provide, and will cause their
affiliates to provide, one another with such cooperation and information as
either of them reasonably may request of the other in filing any Tax Return,
amended return, or claim for refund; determining a liability for Taxes or a
right to a refund of Taxes; or in conducting any audit or other proceeding in
respect of Taxes.  Such cooperation and information shall include AMR's or
SABRE's, as the case may be, (i) providing to the other party copies of all
relevant Tax Returns, together with accompanying schedules and related work
papers, documents relating to rulings or other determinations by taxing
authorities, and records concerning the ownership and tax basis of property; and
(ii) making its employees available to the other party on a mutually convenient
basis to provide reasonable technical support (including, without limitation,
the provision of interpretation, analyses, and testimony).  Any information
obtained under this Section shall be kept confidential, except as may be
otherwise necessary in connection with the filing of returns or claims for
refund or in conducting any audit or other proceeding.

          (b)    PREPARATION OF TAX PACKAGE BY SABRE.  So as to enable AMR to
prepare the Consolidated Returns accurately and completely, to forecast and plan
with respect to Taxes effectively, and to provide for accurate financial
reporting in respect of Taxes, for each Post-Effective Date Tax Period, SABRE
shall prepare and submit to AMR (i) a tax return package for Consolidated
Returns, (ii) an estimated tax package for Consolidated Returns,


                                          15

<PAGE>

(iii) a tax provision package, and (iv) a tax projection package (collectively,
the "Tax Package").  SABRE shall prepare and submit to AMR the Tax Package at
such times and in such form, manner, and medium as AMR shall request.  To the
extent that AMR requests, the Tax Package will include work papers and other
supporting documentation.  Unless otherwise expressly consented to by AMR in
writing, the Tax Package shall be prepared, with respect to Tax Items includable
in a Consolidated Return, using the methods, elections, and positions that AMR
previously used in preparing Consolidated Returns or consolidated financial
statements.  SABRE shall bear all costs and expenses of preparation and
submission of the Tax Package, including, without limitation, accountants' and
attorneys' fees.

          (c)    RECORD RETENTION.  Each party will retain all Tax Returns,
SABRE Pro Forma Consolidated Returns, schedules and work papers, and all
material records or other documents relating thereto, until the expiration of
the statute of limitations (including extensions) of the taxable periods to
which such Tax Returns and other documents relate and, unless such Tax Returns
and other documents are offered to the other party, until the Final
Determination of any payments which may be required in respect of such years
under this Agreement.  Before any tax records or documents are destroyed, the
party holding such records shall notify the other party of its intent to destroy
them and shall offer any such records to the other party.  If the other party
wishes to receive such records, it shall notify the party holding the records or
documents within 45 days of receipt of notice of the other party's intent to
destroy, and will be liable for any costs related to the transfer of such
records.

          (d)    FAILURE TO PROVIDE INFORMATION.  If any AMR Company or SABRE
Company, as the case may be, fails to provide any information requested pursuant
to this Agreement by (i) the dates established for such information in this
Agreement or (ii) with respect to information for which a date is not specified
in this Agreement, within a reasonable period, as determined in good faith by
the party requesting information, the requesting party shall have the right to
engage a public accountant of its choice to gather such information.  AMR and
SABRE, as the case may be, agree that upon 10 days' notice, in the case of a
failure to provide information on the dates established therefor by this
Agreement, and otherwise upon 30 days' notice after the expiration of such
reasonable period, to permit (for the sole purpose of gathering such
information) any such public accountant full access to all appropriate records
or other information in the possession of any member of any AMR Company or any
SABRE Company, as the case may be, during reasonable business hours, and to
reimburse or pay directly all reasonable costs and expenses in connection with
the engagement of such public accountant.
