to Assignee pursuant to Section 2, Assignor hereby contributes to Assignee
$52,680,000 in cash (the "Cash Contribution Amount"); provided that:

                  (i) if there is a Working Capital Deficit (as defined below)
of more than $2,000,000, the Cash Contribution Amount shall be increased by an
amount equal to the excess of the Working Capital Deficit over $2,000,000; and

                  (ii) if there is a Working Capital Surplus (as defined below)

current liabilities over Assignee's current assets (excluding the Cash

accounting principles applied consistent with past practice.

                  "Working Capital Surplus" means the excess of Assignee's
current assets over Assignee's current liabilities (excluding the Cash
Contribution Amount) determined immediately after the transfer contemplated
hereby and prior to the Effective Time in accordance with generally accepted
accounting principles applied consistent with past practice.

         4. THIRD PARTY CONSENTS. Notwithstanding the provisions of Section 2,
this Agreement shall not constitute an assignment or transfer to Assignee of any
interest in, or right or obligation under, any Contract, lease, license or other
agreement, or title to any asset or property,

                                     - 4 -
<PAGE>   8

if an assignment or transfer, or an attempt to make such an assignment or
transfer, without the consent of any party other than Assignor or its Affiliates
would constitute a breach or violation thereof, unless and until such consent
has been obtained. Assignor hereby agrees to use all commercially reasonable
efforts to obtain any such consent, and upon the receipt of such consent, such
interest, right or obligation shall automatically be and be deemed to have been
contributed, transferred and assigned to, or assumed by, Assignee as of the
Assignment Effective Date. Prior to the receipt of such consent, Assignor shall
use all commercially reasonable efforts to give to Assignee all of the economic,
operational and other benefits of such interest or right; provided, however,
that Assignee shall pay or satisfy the corresponding Transferred Obligations
(assuming, for purposes of this proviso, that the asset or property had been
transferred) for the continued enjoyment of such benefit.

         5. TRANSFERRED OBLIGATIONS. Except for the Excluded Obligations,
Assignee hereby consents to be bound by the terms of any and all Contracts (to
the same extent as the Assignor was so bound) and assumes and agrees to pay,
satisfy, honor, perform and discharge, as and when due, and (where applicable)
otherwise in accordance with the Contracts, from the Assignment Effective Date,
all liabilities, obligations, debts, contracts and commitments of any kind,
character or description of Assignor primarily relating to, or arising under or
in respect of, the Contributed Assets, whether absolute, accrued, liquidated,
unliquidated, contingent, executory or otherwise arising, whether before or
after the Assignment Effective Date including, without limitation, the
payroll-related liabilities and other obligations set forth on Schedule 12
attached hereto (collectively, the "TRANSFERRED OBLIGATIONS").

         6. EXCLUDED OBLIGATIONS. Assignor does not hereby assign, Assignee does
not hereby assume and shall not be responsible for, and the term "Transferred
Obligations" shall not include, the Excluded Obligations set forth on Schedule
13 attached hereto.

         7. POWER OF ATTORNEY. Assignor hereby constitutes and appoints Assignee
the true and lawful attorney of Assignor with full power of substitution, in the
name of Assignor or otherwise, and on behalf and for the benefit of Assignee, to
demand and receive from time to time any and all Contributed Assets; to give
receipts, releases and acquittances for or in respect of the same or any part
thereof; to collect, for the account of Assignee, all receivables and other
items transferred to Assignee as provided herein, and to endorse with the name
of Assignor any check received on account of any such receivables or any other
item; from time to time to institute and prosecute in the name of Assignor (upon
written notice to Assignor) or otherwise any and all proceedings at law, in
equity or otherwise, which Assignee may deem proper to collect, assert or
enforce any claim, right, title, debt or account hereby assigned and transferred
or intended so to be; and to take any action otherwise necessary or desirable to
effect the transfer to Assignee of full legal title in and to, and beneficial
ownership of, the Contributed Assets. Assignor hereby declares that the
foregoing powers are coupled with an interest and shall not be revocable by
Assignor in any manner or for any reason.

         8. SUFFICIENCY OF ASSETS. Assignor hereby represents and warrants to
assignee that the assets conveyed pursuant to this Agreement, together with (i)
the assets conveyed pursuant to the Bill of Contribution, Assignment and
Assumption Agreement dated the date hereof between TSGL Holding, Inc. and
Assignee and (ii) the rights of Assignee under the Ancillary Agreements

                                     - 5 -

(as defined in the Merger Agreement), include all of the assets and properties
required to operate the Travelocity Business substantially in the manner it is
being conducted and operated as of the date hereof.

         9. FURTHER ASSURANCES. At any time and from time to time after the
Assignment Effective Date:

                  (a) at the request of Assignee and without further
consideration, Assignor will execute and deliver such further assignments,
instruments of transfer, bills of sale, bills of contribution, powers of
attorney and other conveyances, and will perform all such other acts, as may be
necessary or desirable to vest in Assignee title to and enjoyment of the
Contributed Assets. Assignor will transfer and deliver to the account of
Assignee any cash or other property that Assignor may receive in respect of any
Contributed Asset; and

                  (b) at the request of Assignor and without further
consideration, Assignee will execute and deliver such further assignments,
instruments of transfer, bills of sale, bills of contribution, powers of
attorney and other conveyances, and will perform all such other acts, as may be
necessary or desirable to vest in Assignee title to and enjoyment of the
Contributed Assets and to effectuate the assumption of the Transferred
Obligations.

                  (ii)     ANY IMPLIED WARRANTY ARISING FROM COURSE OF DEALING,
                           COURSE OF PERFORMANCE OR USAGE OF TRADE.

                  (b) ASSIGNOR WILL NOT BE LIABLE TO ASSIGNEE FOR DAMAGES, AND
ASSIGNEE HEREBY RELEASES ASSIGNOR FROM ANY LIABILITY FOR DAMAGES, ARISING UNDER
ANY THEORIES OF LEGAL LIABILITY, TO THE FULLEST EXTENT THAT ASSIGNEE MAY LEGALLY
AGREE TO RELEASE ASSIGNOR FROM LIABILITY FOR SUCH DAMAGES; PROVIDED, HOWEVER,
THAT ASSIGNEE DOES NOT RELEASE ASSIGNOR FROM ANY LIABILITY ARISING SOLELY FROM
THE WILLFUL MISCONDUCT OR GROSS NEGLIGENCE OF ASSIGNOR (UNLESS

HAVE NO OBLIGATION OR LIABILITY UNDER ANY "THEORIES OF LEGAL LIABILITY" (AS SUCH
PHRASE IS USED IN SECTION 10(b)) FOR LOSS OF USE, REVENUE OR PROFIT OR FOR ANY
OTHER INCIDENTAL OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY DEFECT IN, OR USE
OR OWNERSHIP OF, ANY CONTRIBUTED ASSET.

                  (d) As used in this Section 10, the term "Assignor" shall
include Holdings, Travelocity.com and all directors, officers, stockholders,
affiliates, employees, agents, attorneys and representatives of Assignor,

                  (e) Full Negotiation by Parties. THE PARTIES ACKNOWLEDGE THAT
THIS SECTION 10 HAS BEEN THE SUBJECT OF FULL DISCUSSION AND NEGOTIATION BETWEEN

DISCLAIMERS AND RELEASES SET FORTH HEREIN.

         11. EFFECTIVENESS OF AGREEMENT. This Agreement shall not be effective

Party hereby irrevocably consents in advance to the personal jurisdiction of the
District Court of Tarrant County, Texas, Fort Worth Division or the United

Schedules, Exhibits, Appendices, and other documents attached hereto, each of
which is incorporated into this Agreement by this reference) constitutes the
full and complete statement of the agreement of the Parties with respect to the
subject matter hereof and supersedes any previous agreements, understandings or
communications, whether written or oral, relating to such subject matter. Any

         14. AMENDMENTS; WAIVER. This Agreement may be amended, modified or
supplemented only by a written instrument executed by each Party hereto. Any
terms and conditions varying from this Agreement on any order, invoice or other
notification from either Party are not binding on the other Party unless
specifically accepted in writing by the other Party hereto. Unless otherwise
expressly provided in this Agreement, a delay or omission by either Party to
exercise any right or power under this Agreement will not be construed to be a
waiver thereof. No waiver of any breach of any provision of this Agreement will
constitute a waiver of any other prior, concurrent or subsequent breach of the
same or any other provision hereof.

         15. BINDING NATURE; ASSIGNMENT. This Agreement will be binding on the
Parties and their successors and permitted assigns. Neither Party may, nor will

         16. THIRD PARTY BENEFICIARIES. This Agreement is entered into solely
between, and may be enforced only by, Assignor and Assignee, and this Agreement

customers of a Party, or to create any obligations of a Party to any such third
parties.

provided in this Agreement, if an agreement, approval, acceptance, consent or
similar action is required of either Party or its Affiliates by any provision of
this Agreement, or otherwise to effect the transactions contemplated by this
Agreement, such action will not be unreasonably withheld or delayed. An approval
or consent given by a Party under this Agreement will not relieve the other
Party from responsibility for complying with the requirements of this Agreement,
nor will it be construed as a waiver of any rights under this Agreement, except
as and to the extent otherwise expressly provided in such approval or consent.

         18. NOTICES. All notices under this Agreement will be in writing and

interpretation, judgment, order or injunction of any Governmental Authority. The
Parties acknowledge and agree that each has participated in the drafting of this
Agreement and that this Agreement will not be construed in favor of or against
either Party solely on the basis of a Party's drafting or participation in the
drafting of any portion of this Agreement. This Agreement may be executed in

such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the remaining provisions of this
Agreement. Any such provision shall not invalidate or otherwise render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, each Party waives any provision of law which renders any
provision of this Agreement invalid, illegal or unenforceable in any respect.

         22. HEADINGS. The section headings herein are for convenience of
reference only, do not constitute part of this Agreement, and shall not be
deemed to limit or otherwise affect any of the provisions hereof.

personal property leases, licenses, purchase orders, sales orders and other
instruments, agreements and arrangements that are listed on Schedule 3 attached

         3. THIRD PARTY CONSENTS. Notwithstanding the provisions of Section 2,
this Agreement shall not constitute an assignment or transfer to Assignee of any
interest in, or right or obligation under, any Contract, lease, license or other
agreement, or title to any asset or property, if an assignment or transfer, or
an attempt to make such an assignment or transfer, without the consent of any
party other than Assignor or its Affiliates would constitute a breach or
violation thereof, unless and until such consent has been obtained. Assignor
hereby agrees to use all commercially reasonable efforts to obtain any such
consent, and upon the receipt of such consent, such interest, right or
obligation shall automatically be and be deemed to have been contributed,
transferred and assigned to, or assumed by, Assignee as of the Assignment
Effective Date. Prior to the receipt of such consent, Assignor shall use all
commercially reasonable efforts to give to Assignee all of the economic,
operational and other benefits of such interest or right; provided, however,
that Assignee shall pay or satisfy the corresponding Transferred Obligations
(assuming, for purposes of this proviso, that the asset or property had been
transferred) for the continued enjoyment of such benefit.

         4. TRANSFERRED OBLIGATIONS. Except for the Excluded Obligations,
Assignee hereby consents to be bound by the terms of any and all Contracts (to
the same extent as the Assignor was so bound) and assumes and agrees to pay,
satisfy, honor, perform and discharge, as and when due, and (where applicable)
otherwise in accordance with the Contracts, from the Assignment Effective Date,
all liabilities, obligations, debts, contracts and commitments of any kind,
character or description of Assignor primarily relating to, or arising under or
in respect of, the Contributed Assets, whether absolute, accrued, liquidated,
unliquidated, contingent, executory or otherwise arising, whether before or
after the Assignment Effective Date including, without limitation, the
payroll-related liabilities and other obligations set forth on Schedule 5
attached hereto (collectively, the "TRANSFERRED OBLIGATIONS").

         5. EXCLUDED OBLIGATIONS. Assignor does not hereby assign, Assignee does
not hereby assume and shall not be responsible for, and the term "Transferred
Obligations" shall not include, the Excluded Obligations set forth on Schedule 6
attached hereto.

         6. POWER OF ATTORNEY. Assignor hereby constitutes and appoints Assignee
the true and lawful attorney of Assignor with full power of substitution, in the
name of Assignor or otherwise, and on behalf and for the benefit of Assignee, to
demand and receive from time to time any and all Contributed Assets; to give
receipts, releases and acquittances for or in respect of the

                                     - 3 -

same or any part thereof; to collect, for the account of Assignee, all
receivables and other items transferred to Assignee as provided herein, and to
endorse with the name of Assignor any check received on account of any such
receivables or any other item; from time to time to institute and prosecute in
the name of Assignor (upon written notice to Assignor) or otherwise any and all
proceedings at law, in equity or otherwise, which Assignee may deem proper to
collect, assert or enforce any claim, right, title, debt or account hereby
assigned and transferred or intended so to be; and to take any action otherwise
necessary or desirable to effect the transfer to Assignee of full legal title in
and to, and beneficial ownership of, the Contributed Assets. Assignor hereby
declares that the foregoing powers are coupled with an interest and shall not be
revocable by Assignor in any manner or for any reason.

         7. FURTHER ASSURANCES. At any time and from time to time after the
Assignment Effective Date:

         (a)      at the request of Assignee and without further consideration,
                  Assignor will execute and deliver such further assignments,
                  instruments of transfer, bills of sale, bills of contribution,
                  powers of attorney and other conveyances, and will perform all
                  such other acts, as may be necessary or desirable to vest in
                  Assignee title to and enjoyment of the Contributed Assets.
                  Assignor will transfer and deliver to the account of Assignee
                  any cash or other property that Assignor may receive in
                  respect of any Contributed Asset; and

         (b)      at the request of Assignor and without further consideration,

                  to effectuate the assumption of the Transferred Obligations.

         ASSIGNMENT EFFECTIVE DATE. TO THE FULLEST EXTENT PERMITTED BY LAW,
         ASSIGNOR EXPRESSLY DISCLAIMS ALL REPRESENTATIONS AND WARRANTIES WITH
         RESPECT TO THE CONDITION, QUALITY, UTILITY OR VALUE OF ANY AND ALL OF
         THE CONTRIBUTED ASSETS, WHETHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT
         LIMITATION:

                  (i)      ANY STATUTORY OR IMPLIED WARRANTY OF MERCHANTABILITY

         (b) ASSIGNOR WILL NOT BE LIABLE TO ASSIGNEE FOR DAMAGES, AND ASSIGNEE
         HEREBY RELEASES ASSIGNOR FROM ANY LIABILITY FOR DAMAGES, ARISING UNDER
         ANY THEORIES OF LEGAL LIABILITY, TO THE FULLEST EXTENT THAT ASSIGNEE
         MAY LEGALLY AGREE TO RELEASE ASSIGNOR FROM LIABILITY FOR SUCH DAMAGES;
         PROVIDED, HOWEVER, THAT ASSIGNEE DOES NOT RELEASE ASSIGNOR FROM ANY
         LIABILITY ARISING SOLELY FROM THE WILLFUL MISCONDUCT OR GROSS
         NEGLIGENCE OF ASSIGNOR (UNLESS ATTRIBUTED OR IMPUTED TO ASSIGNOR BY
         REASON OF ANY ACT OR OMISSION OF ASSIGNEE WHETHER AS AGENT FOR ASSIGNOR
         OR OTHERWISE). "THEORIES OF LEGAL LIABILITY" AS USED IN THIS SECTION
         8(B) INCLUDE, BUT ARE NOT LIMITED TO, CONTRACT, TORT, STRICT LIABILITY,
         BREACH OF EXPRESS OR IMPLIED WARRANTY, BREACH OF IMPLIED COVENANT AND
         THE SOLE OR CONCURRENT NEGLIGENCE OF ASSIGNOR OR ANY PERSON WHOSE
         NEGLIGENCE, DUTIES, ACTIONS OR LIABILITIES MAY BE ATTRIBUTED OR IMPUTED
         TO ASSIGNOR.

         (c) No Consequential or Incidental Damages. ASSIGNOR SHALL HAVE NO
         OBLIGATION OR LIABILITY UNDER ANY "THEORIES OF LEGAL LIABILITY" (AS
         SUCH PHRASE IS USED IN SECTION 8(b)) FOR LOSS OF USE, REVENUE OR PROFIT
         OR FOR ANY OTHER INCIDENTAL OR CONSEQUENTIAL DAMAGES WITH RESPECT TO
         ANY DEFECT IN, OR USE OR OWNERSHIP OF, ANY CONTRIBUTED ASSET.

         (d) As used in this Section 8, the term "Assignor" shall include all
         directors, officers, stockholders, affiliates, employees, agents,
         attorneys and representatives of Assignor.

         (e) Full Negotiation by Parties. THE PARTIES ACKNOWLEDGE THAT THIS
         SECTION 8 HAS BEEN THE SUBJECT OF FULL DISCUSSION AND NEGOTIATION
         BETWEEN THE PARTIES AND THAT THE PROVISIONS OF THIS AGREEMENT WERE
         ARRIVED AT IN CONSIDERATION OF THE PROVISIONS AND EFFECTS OF THIS
         SECTION 8, INCLUDING THE DISCLAIMERS AND RELEASES SET FORTH HEREIN.

         9. EFFECTIVENESS OF AGREEMENT. This Agreement shall not be effective
and shall not legally bind the parties until the Assignment Effective Date.

         10. SUBMISSION TO JURISDICTION. As part of the consideration for value
received pursuant to this Agreement, and regardless of the location of any
present or future domicile or principal place of business of either Party, each
Party hereby irrevocably consents in advance to the personal jurisdiction of the
District Court of Tarrant County, Texas, Fort Worth Division or the United
States District Court for the Northern District of Texas, Fort Worth Division,
to hear

                                     - 5 -

and determine any Disputes brought against such party by the other party and
pertaining to this Agreement or to any matter relating to or arising out of this
Agreement.

         11. ENTIRE AGREEMENT; SURVIVAL. This Agreement (including all
Schedules, Exhibits, Appendices, and other documents attached hereto, each of
which is incorporated into this Agreement by this reference) constitutes the
full and complete statement of the agreement of the Parties with respect to the
subject matter hereof and supersedes any previous agreements, understandings or
communications, whether written or oral, relating to such subject matter. Any
provision of this Agreement which contemplates performance or observance
subsequent to any termination or expiration of this Agreement will survive any
termination or expiration of this Agreement and continue in full force and
effect. The disclaimers and releases under Section 8 hereof shall survive
forever.

         12. AMENDMENTS; WAIVER. This Agreement may be amended, modified or
supplemented only by a written instrument executed by each Party hereto. Any
terms and conditions varying from this Agreement on any order, invoice or other
notification from either Party are not binding on the other unless specifically
accepted in writing by the other. Unless otherwise expressly provided in this
Agreement, a delay or omission by either Party to exercise any right or power
under this Agreement will not be construed to be a waiver thereof. No waiver of
any breach of any provision of this Agreement will constitute a waiver of any
other prior, concurrent or subsequent breach of the same or any other provision
hereof.

         13. BINDING NATURE; ASSIGNMENT. This Agreement will be binding on the
Parties and their successors and permitted assigns. Neither Party may, nor will
it have the power to, assign this Agreement, or any part hereof, without the
prior written consent of the other. Any attempted assignment in violation of
this Agreement shall be null and void ab initio.

         14. THIRD PARTY BENEFICIARIES. This Agreement is entered into solely
between, and may be enforced only by, Assignor and Assignee, and this Agreement
will not be deemed to create any rights in any third parties, including any
customers of a Party, or to create any obligations of a Party to any such third
parties.

         15. APPROVALS AND SIMILAR ACTIONS. Except as otherwise expressly
provided in this Agreement, if an agreement, approval, acceptance, consent or
similar action is required of either Party or its Affiliates by any provision of
this Agreement, or otherwise to effect the transactions contemplated by this
Agreement, such action will not be unreasonably withheld or delayed. An approval
or consent given by a Party under this Agreement will not relieve the other
Party from responsibility for complying with the requirements of this Agreement,
nor will it be construed as a waiver of any rights under this Agreement, except
as and to the extent otherwise expressly provided in such approval or consent.

         16. NOTICES. All notices under this Agreement will be in writing and
will be deemed to have been duly given if delivered personally or by a
nationally recognized courier service, faxed, electronically mailed or mailed by
registered or certified mail, return receipt requested, postage prepaid, to the

         17. CONSTRUCTION RULES; COUNTERPARTS. In performing its obligations
under this Agreement, neither Party will be required to undertake any activity
that would conflict with the requirements of any applicable law, rule,
regulation, interpretation, judgment, order or injunction of any Governmental
Authority. The Parties acknowledge and agree that each has participated in the
drafting of this Agreement and that this Agreement will not be construed in
favor of or against either Party solely on the basis of a Party's drafting or
participation in the drafting of any portion of this Agreement. This Agreement
may be executed in multiple counterparts, each of which will be deemed an
original and all of which taken together will constitute one instrument.

         18. GOVERNING LAW. This Agreement will be governed by and construed in
accordance with the substantive laws of the State of New York, without giving
effect to any choice-of-law rules that may require the application of the laws
of another jurisdiction.

         19. ENFORCEABILITY; SEVERABILITY. Any provision of this Agreement which
is held to be invalid, illegal or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the remaining provisions of this
Agreement. Any such provision shall not invalidate or otherwise render
unenforceable such provision

in any other jurisdiction. To the extent permitted by applicable law, each party
waives any provision of law which renders any provision of this Agreement
invalid, illegal or unenforceable in any respect.

         20. HEADINGS. The section headings herein are for convenience of
reference only, do not constitute part of this Agreement, and shall not be
deemed to limit or otherwise affect any of the provisions hereof.
