                              PROGRAM LEASE AGREEMENT


This PROGRAM LEASE AGREEMENT ("Agreement") is made this 30th day of 
September, 1998 (hereafter the "Effective Date"), by and between Comdisco, 
Inc., a Delaware corporation, with its principal office at 6111 N. River 
Road, Rosemont, IL 60018, as Lessor ("Comdisco"), and The SABRE Group, Inc., 
a Delaware corporation, with its principal office at 4255 Amon Carter Blvd., 
Dallas/Fort Worth, Texas 76155, as Lessee ("SABRE").

                                 GENERAL PROVISIONS

Comdisco has established a Global Technology Program (the "Program") for 
SABRE's global technology environment.  The Program initially includes 
mainframe Equipment as listed in the applicable Equipment Schedules to the 
Agreement is now or hereafter attached hereto as Attachment A (and shall be 
consecutively numbered A-1 through A-__, as applicable), but, upon SABRE's 
written notice to Comdisco can be expanded to include midrange and/or other 
equipment, as further provided herein. The Program also includes a suite of 
services provided by Comdisco to SABRE in accordance with the terms of this 
Agreement, and the Services Schedule attached as Schedule 1 and made part of 
the Operative Agreement (as defined below).  Additionally, in order to assist 
SABRE in the acquisition, management and deployment of its technology, 
Comdisco shall purchase a portion of SABRE's equipment and/or take over 
payment responsibility for, a portion of SABRE's current third party leases 
(as applicable) as provided for herein and in the Operative Agreements.

As part of the Program, SABRE has the ability to remove Equipment from 
the Program, and at SABRE's option, replace and/or augment the Equipment with 
a supply of Growth Equipment and Refresh Equipment under the terms of this 
Agreement and the Operative Agreements. [TEXT OMITTED - CONFIDENTIAL TREATMENT 
REQUESTED]. The total scope of this Program is to provide up to the equivalent 
of US $[TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] of Growth Equipment 
and Refresh Equipment to SABRE over the Term (as defined in Section 3.1) of 
this Agreement.  This amount can be increased upon agreement of the parties.

The parties intend and agree that the provisions of the Program are intended 
to be applicable regardless of the country or jurisdiction in which Equipment 
is located or proposed to be located or relocated, or in which Equipment 
Services (as defined herein) are or are proposed to be performed.  If either 
Comdisco or SABRE deems it advisable to undertake any of the activities 
contemplated in connection with the Program in a country other than the 
United States through a subsidiary or affiliate, it agrees that it will cause 
such a subsidiary or affiliate, to the extent the party has the power to 
cause such subsidiary or affiliate to act, to do so in accordance with the 
terms and conditions of this Agreement and the Operative Agreements. The 
parties further agree that to the extent additional Operative Agreements are 
required in connection with the addition of Equipment or the provision of 
Equipment Services, the terms and conditions of such Operative Agreements 
will be consistent with the terms and conditions of the Agreement, except as 
may be mutually agreed or as provided herein.

If the application of the terms and conditions of this Agreement in a 
particular country or jurisdiction would, in the reasonable opinion of one of 
the parties, result in a substantially adverse tax, accounting or other 
financial consequences to one of the parties, or if one party is unable to 
cause a subsidiary or affiliate to provide such term or condition or be 
prohibited by law in such country or jurisdiction, the parties agree to 
negotiate in good faith to enter into such additional Operative Agreements 
under terms and conditions which provide substantially the same economic 
benefits for each of the parties as would otherwise be provided but for such 
adverse consequences or limitation.  Comdisco specifically acknowledges and 
agrees, however, that SABRE is entering into this Agreement and the Operative 
Agreements in reliance upon and in consideration of Comdisco's agreements 
with respect to the Program on a global basis, but not limited to, the 
Equipment Services, and the rights and duties of the parties with respect 
thereto.

4.   MONTHLY RENTAL AND ADJUSTMENTS TO MONTHLY RENTAL

     4.1  RENTAL AMOUNT AND PAYMENT TERMS. SABRE agrees to pay Comdisco the
          Monthly Rental which is  listed on an applicable Equipment Schedule,
          plus applicable taxes that SABRE is required to pay pursuant to
          Section 4.3, 5.7 and 7.1 of this Agreement (or as otherwise provided
          for in a Non-US Equipment Schedule), as adjusted as provided herein. 
          As Equipment is added (Growth Equipment), deleted, or replaced
          (Refresh Equipment) under such Equipment Schedule, the Monthly Rental
          shall be adjusted monthly (or as otherwise provided under the
          Operative Agreements) as provided for under this Agreement and the
          Operative Agreements.  Except as otherwise provided in Section 4.6,
          the Monthly Rental (other than a Disputed Amount) will be due and
          payable in arrears on the last day of each month of the Initial Term,
          subject to the terms and conditions hereof.  If the last day of a
          month occurs on a Saturday, Sunday or legal holiday (as denoted by the
          government of the country in which payment is required to occur) then
          such payment shall be due and payable on the next business day. 
          Payments of Monthly Rental shall be made at the location(s) and in the
          currency(s) specified in the applicable Equipment Schedule. 
         
          The Monthly Rental due under the U.S. Equipment Schedule is comprised
          of, with respect to Equipment, a fixed portion (the "Fixed Equipment
          Portion") and a variable portion (the "Variable Equipment Portion"),
          and with respect to Services, a separate portion (the "Services
          Portion").  As of the start of the Initial Term, the Monthly Rental is
          as provided

          below, plus applicable taxes (if any) that SABRE is required to pay 
          pursuant to Section 4.3, 5.7 and 7.1 hereof or as otherwise provided 
          for in a Non-US Equipment Schedule, of which $[TEXT OMITTED - 
          CONFIDENTIAL TREATMENT REQUESTED] is the Fixed Equipment Portion, 
          $[TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] is the Variable 
          Equipment Portion, and $[TEXT OMITTED - CONFIDENTIAL TREATMENT 
          REQUESTED] is the Services Portion.
         
         4.2   NET LEASE.  Except as required by law or as otherwise provided
               for in the Agreement, each Equipment Schedule constitutes a net
               lease. [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED].

     4.3  TAXES.
          (a)  ALLOCATION OF RESPONSIBILITY FOR TAXES.   SABRE shall be
          responsible for, and shall indemnify Comdisco for, state and local
          sales and use taxes and value added taxes (including penalty and
          interest) imposed on, based on, or measured by any payments of Monthly
          Rental pursuant to this Agreement.  Where permitted by law, Comdisco
          shall be responsible for claiming a resale exemption for state and
          local sales taxes and use taxes and value added taxes imposed on,
          based on, or measured by any amounts paid for Comdisco's acquisition,
          ownership, or use of property or services to Comdisco to be resold to
          SABRE.  Comdisco shall indemnify SABRE for such taxes (including
          penalty and interest), if Comdisco's failure to properly claim this
          exemption results in additional taxes imposed on SABRE.  With respect
          to sales, use and value added taxes imposed by those states and local
          jurisdictions that do not provide a resale exemption, Comdisco shall
          pay the applicable tax due and SABRE shall reimburse Comdisco for such
          tax to the extent such tax is imposed on property sold or leased to
          SABRE by Comdisco.  Except as provided for in the preceding sentence,
          Comdisco shall be responsible for and shall indemnify SABRE for state,
          and local sales and use taxes and value added taxes (including penalty
          and interest) imposed on, based on, or measured by any amounts paid
          for Comdisco's acquisition, ownership, or use of property or services,
          or the transfer or provision of property or services to Comdisco. Each
          of SABRE and Comdisco shall be responsible for taxes based on or
          measured by its own net or gross income, net or gross receipts (except
          for state and local sales and use taxes and value added taxes),
          capital, net worth, and for franchise and similar taxes.  If a party
          incurs any taxes based on or measured by the other party's net or
          gross income, net or gross receipts (except for state and local sales
          and use taxes and value added taxes), capital, net worth, and for
          franchise and similar taxes of the other party, then such other party
          shall indemnify the party incuring the taxes.

<PAGE>

          (b)  PROPERTY TAXES.  SABRE is responsible for the reporting and
          payment of any ad valorem taxes due on property owned by it or leased
          by it from a third party and Comdisco shall be responsible for the
          filing of such tax returns on Comdisco owned property.  SABRE shall
          reimburse Comdisco for ad valorem taxes on property leased by Comdisco
          to SABRE pursuant to this Agreement if SABRE has been provided with
          all the rights and opportunities to contest such taxes, including the
          right to contest the valuation upon which such taxes are based, that
          would have been available to SABRE if SABRE had been the owner of the
          Equipment instead of the lessee.

          (c)  CONTESTS AND CLAIMS FOR REFUNDS.  If Comdisco or SABRE receives
          notice from any taxing authority with respect to an assessment or
          potential assessment or imposition of any tax that the other party
          ("Tax Indemnifying Party") would be responsible for pursuant to this
          Section 4, then Comdisco or SABRE, as the case may be, shall notify
          the Tax Indemnifying Party in writing of such notice so as to allow
          the Tax Indemnifying Party sufficient time prior to the expiration of
          any period during which contests may be filed to file a contest of the
          tax, and shall, at the Tax Indemnifying Party's written request,
          contest or permit the Tax Indemnifying Party to contest such proposed
          tax at its own expense.  The Tax Indemnifying Party may require the
          other party to apply, at the expense of the Tax Indemnifying Party,
          for a refund of taxes otherwise subject to reimbursement or
          indemnification under this Section 4.  In lieu of pursuing such a
          refund claim, Comdisco or SABRE, as the case may be, may assign its
          rights to a refund claim to the Tax Indemnifying Party.  SABRE and
          Comdisco shall cooperate in good faith in any contest or claim for
          refund pursuant to this Section 4.

          (d)  REFUNDS.  Comdisco or SABRE, as the case may be, shall promptly
          pay over to the other party, an amount equivalent to any refund,
          credit, offset or abatement (including interest thereon) received by
          Comdisco or SABRE, as the case may be, of taxes, to the extent such
          refunds, credits, offsets, or abatements are of amounts that were paid
          by the other party to either Comdisco or SABRE, as the case may be, or
          to a taxing authority pursuant to this Section 4.

          (e)  COOPERATION.  Each party shall provide the other with such
          cooperation as such other party may reasonably request in minimizing
          taxes incurred in connection with this Agreement.  In the case of
          SABRE, such cooperation shall include providing Comdisco any
          applicable resale certificates; information regarding out-of-state use
          of materials, services, or sales; or other exemption certificates.  In
          the case of Comdisco, such cooperation shall include providing SABRE
          applicable information regarding out-of-state delivery or use of
          materials, services or sales; providing prompt notice of the
          occurrence of any condition or event which causes, SABRE to be liable
          to pay any amount under this Section 4, and at the request of SABRE,
          taking steps reasonably available to Comdisco to minimize taxes; such
          steps shall include (but not be limited to) (i) providing itemized (or
          non-itemized) invoices or billing, (ii) separating (or combining)
          services provided pursuant to this Agreement, (iii) changing the
          location at which services or property are delivered, provided or used
          pursuant to this Agreement, (iv) permitting SABRE to assign to an
          affiliate all or part of its rights under this Agreement, including
          the right to take delivery of services or property and (v) using
          commercially reasonable efforts to require any third party to take
          steps reasonably available to such party to minimize taxes.  In the
          case of 

REVISED 12/04/98      SABRE GROUP, INC. AND COMDISCO, INC.                   16
                                 CONFIDENTIAL
<PAGE>

          SABRE and Comdisco, such cooperation shall also include providing 
          its value added registration numbers to the other party for any 
          jurisdiction for which recoverable value added taxes were paid,
          maintaining records as reasonably necessary for tax purposes; making
          such records available to the other party (or permitting the other
          party to copy, at its expense, such records); and making information
          in its possession and employees with technical expertise available as
          reasonably necessary in connection with the preparation of any tax
          returns or any audit or tax contest or refund claim.

          (f)  SALES AND USE TAXES.  Notwithstanding anything to the contrary in
          this Agreement or any other agreement between Comdisco and SABRE,
          SABRE shall not be responsible for or obligated to indemnify Comdisco
          for, and Monthly Rental shall not include, (a) any taxes other than
          sales or use or value added taxes imposed on or with respect to the
          transfer of Equipment or services from Comdisco to SABRE or (b) any
          sales or use taxes or value added taxes with respect to any item of
          Equipment to the extent such taxes exceed the amount of such taxes for
          which SABRE would have been responsible if either (x) it had purchased
          or leased the item of Equipment directly from a third party vendor or
          (y) with respect to items of equipment that are sold to Comdisco by
          SABRE pursuant to a sales agreement, if it had not sold the items of
          equipment to Comdisco.

          (g)  EXCLUSIONS.  Notwithstanding anything to the contrary in this
          Agreement or any other agreement (including Section 17 of this
          Agreement) between Comdisco and SABRE, neither party shall be
          responsible for, or required to indemnify the other party ("Tax
          Indemnified Party") for: (i) taxes resulting from the willful
          misconduct or gross negligence of the Tax Indemnified Party; (ii)
          taxes either not yet due or payable, or taxes being contested in
          accordance with the provisions of this Section 4; (iii) any
          withholding taxes imposed on the net or gross income of the Tax
          Indemnified Party; (iv) taxes that result from any failure of the Tax
          Indemnified Party to file timely reports or returns or to pay any
          taxes when due, or to comply with any certification, information,
          documentation, reporting or similar requirements required to obtain or
          establish refund or exemption from such taxes; and (v) penalties and
          interest with respect to such taxes to the extent such penalties or
          interest are imposed as a result of any of the factors listed in
          clauses (i) through (iv) of this section, or as a result of tax return
          positions of the Tax Indemnified Party that are unrelated to this
          Agreement.  The parties further agree that the indemnity provisions in
          Section 10.3 and Section 17 of this Agreement and in any other
          agreement, do not apply to taxes, it being the intent of the parties
          that this Section 4 state the parties' indemnification obligations
          with respect to taxes.
     
          (h)  TAX CHARACTERIZATIONS.  Unless otherwise stated therein, each
          Equipment Schedule hereunder shall be entered into on the basis that
          Comdisco intends to claim as allowed by the Internal Revenue Code such
          deductions for depreciation, interest on purchase money, and other tax
          benefits as are provided to an owner of equipment.  Comdisco is solely
          liable for any tax or other characterizations of law or regulation
          regarding such deductibility.

     4.5  RECONCILIATION ACCOUNT.  SABRE shall have the option to utilize a
          Reconciliation Account more fully described in an Equipment Schedule
          to accumulate changes in the Monthly Rental made pursuant to the
          Refresh Pool Mechanics described herein and in the Equipment Schedule
          which will be reconciled on the Settlement Dates set forth in the
          Equipment Schedule.  Additional Settlement Dates can be called (i) by
          either party if the accumulated adjustment amount exceeds $[TEXT 
          OMITTED - CONFIDENTIAL TREATMENT REQUESTED] accumulated across all 
          active Equipment Schedules; (ii) by the non-defaulting party if a 
          party shall have defaulted in the performance of a material 
          obligation under this Agreement or an Operative Agreement and not 
          otherwise excused or cured during the applicable cure period; (iii) 
          by Comdisco if SABRE shall not be Investment Grade; (iv) by SABRE if 
          Comdisco shall not be Investment Grade; or (v) by either party if a 
          notice of termination has been given, and at SABRE's option the use 
          of the Reconciliation Account can be discontinued in which case the 
          Monthly Rental shall be adjusted as provided herein. Notwithstanding 
          the above, either party may at any time, at its sole option, pay the 
          other party a cash payment to reduce or eliminate the balance in the 
          Reconciliation Account.  SABRE has the ability to transfer all or 
          part of the Reconciliation Account balance from one Equipment Schedule
          to another Equipment Schedule under this Agreement.  Upon notice from 
          SABRE, Comdisco shall cause such amounts to be transferred between 
          Equipment Schedules.  If the two Equipment Schedules are denominated 
          in different currencies, then the amounts being transferred will be 
          converted to the currency of the destination Equipment Schedule at 
          the then current foreign exchange rate for the relevant currencies as 
          quoted in the Spot Close Value New York Composite Rate by Bloomberg 
          as of the close of business (US Eastern Time) as of the date of such 
          notice.
         
     4.6  INVOICES.
          (a)  Comdisco shall provide all invoices in the form and media, and
               with the level of detail as mutually agreed to between the
               parties during the completion of the Life-Cycle Process Analysis
               and Optimization and Optional Implementation task period
               described in the Services Schedule. The parties agree to conduct
               a test or (if required) series of tests encompassing an exchange
               of the agreed upon invoice data between the parties, such test to
               occur on or about the thirtieth day after this Agreement is
               executed by the parties.  In the event such test fails, the
               parties shall diligently pursue avenues to remedy such failure. 
               From time to time, SABRE and Comdisco may agree to changes in the
               form, media and structure of invoices.  Upon the successful
               completion of the aforementioned tests, an invoice that does not
               comply in all material respects with the requirements as to form
               and content that was agreed upon by the parties shall not be
               deemed presented. Upon successful completion of the
               aforementioned tests, Comdisco shall prepare and send to SABRE an
               invoice with the level of detail agreed upon for receipt by SABRE
               on or before the 22nd day of each month reflecting all changes
               received by Comdisco on or before the 15th of that month.  In the
               event SABRE receives such invoice on or before the 23rd day of a
               given month, then SABRE shall pay such invoice on or before the
               last day of such

               month.  In the event SABRE receives an invoice after the 23rd 
               day of a given month, then one day for each day after the 23rd 
               that SABRE receives such invoice shall be added to the date SABRE
               is required to pay such invoice.  Until such time as the parties 
               agree as to form, media, and detail to be contained on the 
               invoice and the successful completion of the aforementioned 
               tests, or SABRE receives an invoice that does not comply with 
               the agreed upon detail, SABRE's obligation to pay any such 
               invoice shall be within 30 days of receipt of such invoice,
               however, SABRE shall endeavor to make payments earlier than such
               30 days.  Comdisco shall promptly credit to SABRE any undisputed
               credits due SABRE under this Agreement and any payments made to
               Comdisco which Comdisco is not entitled hereunder.  Comdisco
               shall refund by check, instead of issuance of credits, when
               SABRE's accounts are current.  [TEXT OMITTED - CONFIDENTIAL

          (b)  [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED].
               
     4.7  WITHHOLD VENDOR PAYMENTS.  If after SABRE's acceptance of any
          Equipment, SABRE provides Comdisco with written notice to withhold
          payment of the purchase price for such Equipment from an Equipment
          vendor or supplier, Comdisco shall withhold such payment until SABRE
          provides Comdisco with an additional written notice instructing
          Comdisco to pay such purchase price; provided, however, SABRE shall
          indemnify Comdisco against any claims and for all costs and expenses
          directly related to such non-payment.

     4.8  AUDITS.
          (a)  SABRE may, from time to time, at its own expense review
               Comdisco's books and records for the purpose of evaluating the
               accuracy of Comdisco's invoices for Monthly Rental, Services
               rendered and Taxes.  SABRE may employ such assistance as it deems
               desirable to conduct such reviews, including an independent
               accounting firm or consultants.
     
          (b)  Comdisco shall cooperate in any SABRE review, providing
               reasonable access to any and all Comdisco employees and all
               Comdisco books, records and other documents reasonably necessary
               to assess the accuracy of Comdisco's invoices as provided above. 
               Any disputes concerning the results of a review shall be referred
               to the parties Project Managers (as defined in the Services
               Schedule) for resolution.  If these individuals cannot resolve
               the dispute within 30 days after the referral, the dispute(s)
               shall be escalated as set forth in Section 13 herein.  Any
               billing errors shall be promptly corrected, including making
               refund of any overpayment by SABRE as provided in Section 4.6(a)
               above and making payment of any underpayments by SABRE.  In the
               event SABRE's audit shows a material error which is defined as in
               excess of [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] 
               percent ([TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED]%) 
               then Comdisco shall be required to reimburse SABRE for the 
               reasonable cost of such audit.  Such [TEXT OMITTED - CONFIDENTIAL
               TREATMENT REQUESTED]% error rate shall be exclusive of monthly 
               fluctuations resulting from Monthly Rental adjustments made 
               pursuant to the Program.
         
     4.9  LATE PAYMENT.  If any scheduled payment by SABRE is not made within
          thirty (30) days following its due date (other than a Disputed
          Amount), interest on such delinquent payment shall accrue from the due
          date until paid at the prime rate as established by Citibank, N.A.
          plus [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] percent ([TEXT 
          OMITTED - CONFIDENTIAL TREATMENT REQUESTED]%)  and shall be payable 
          by SABRE.  Comdisco shall be obligated to provide SABRE with prompt 
          written notice of non-receipt of a payment.  If Comdisco fails to 
          provide such notice then interest charges shall not accrue on the 
          non-Assigned Amount until such date as written notice is provided.

5.   INSTALLATION AND USE OF EQUIPMENT
     5.1  DELIVERY AND INSTALLATION.  SABRE shall be responsible for the cost of
          delivery and installation of all Equipment to the SABRE designated
          delivery location.  Upon the expiration or termination of an Equipment
          Schedule or the early return of any items of Equipment thereunder as
          provided for herein, SABRE shall pay all transportation charges
          (including in-transit insurance) associated with the return of the
          Equipment for a distance equal to the distance between the Equipment
          location and the greater Chicago metropolitan area for locations in
          the U.S.  For locations outside the U.S. SABRE shall pay all
          transportation charges (including in-transit insurance) associated
          with the return of the Equipment for a distance equal to the distance
          between the Equipment location and Comdisco's equipment return
          location in such country, or if there is no Comdisco location in such
          country, then the closest Comdisco equipment return location to such
          Equipment.  Comdisco shall make arrangements for its carrier to pick
          up the Equipment.  Risk of loss of the Equipment shall transfer to
          Comdisco at the time SABRE tenders the Equipment to Comdisco or its
          carrier at the Equipment location for return to Comdisco.

     5.2  USE OF EQUIPMENT.  SABRE shall be entitled to unlimited usage of the
          Equipment for its benefit and/or the benefit of its parents,
          affiliates and Customers, during the Initial Term or any Extension
          Period without extra charge by Comdisco.

     5.3  ACQUIRING GROWTH AND REFRESH EQUIPMENT.  
     
          (a)  As agreed to herein and in the Operative Agreements, in the event
               the Growth or Refresh Equipment is newly manufactured equipment,
               upon SABRE's request, Comdisco shall actively participate in
               negotiations with SABRE including participation in meetings of
               the negotiating team and with suppliers and providing information
               for an acquisition price for such equipment by providing SABRE
               with Comdisco's market watch information based on Comdisco's
               knowledge about recent transactions for such equipment.  Upon
               agreement of an acquisition cost between SABRE and an equipment
               supplier, and if SABRE elects to add such equipment to the
               Program as Growth or Refresh Equipment, SABRE will assign to
               Comdisco its right to purchase such equipment.  In the event the
               Growth or Refresh Equipment is used equipment, Comdisco will
               provide SABRE with the following information:  (i) Comdisco's
               market watch information for such equipment; (ii) whether
               Comdisco has such equipment available in its inventory and if so,
               the related Comdisco supply price; and (iii) other equipment
               suppliers who may have such equipment.  SABRE shall provide
               Comdisco the opportunity to supply such used equipment to SABRE
               and SABRE agrees to acquire such equipment from Comdisco if
               Comdisco's acquisition price and other terms and conditions of
               the proposal are, based on SABRE's commercially reasonable
               business judgment, equal to or better than the proposals obtained
               from other third parties.  In the event SABRE acquires used
               equipment from a third party, and if SABRE elects to add such
               equipment to the Program, SABRE will assign to Comdisco its right
               to purchase such equipment.  SABRE is not under any obligation to
               include equipment it may purchase or lease from others under this
               Program.  Further, SABRE may elect to add equipment it purchases
               or leases from others under this Program as Managed Equipment and
               Comdisco shall provide asset tracking services for such Managed
               Equipment at no additional charge (unless mutually agreed to in
               the Services Schedule) pursuant to the terms of this Agreement
               and the limitation of [TEXT OMITTED - CONFIDENTIAL TREATMENT 
               REQUESTED] assets (as defined in the Services Schedule) as 
               further provided in the Services Schedule.

          (b)  In addition to the other conditions of this Agreement and the
               Operative Agreements, if SABRE shall have (i) [TEXT OMITTED -

          CONFIDENTIAL TREATMENT REQUESTED]. 
          
          Notwithstanding the above, [TEXT OMITTED - CONFIDENTIAL TREATMENT 
          REQUESTED].  Further, Comdisco shall accept return of the Duplicate 
          Equipment as provided for herein, and SABRE shall have the same 
          obligations with respect thereto, including payment of the amounts 
          described in (i) and (ii).  In the event that one, or both, of the 
          parties do not have a legal presence in a country with which SABRE 
          desires to put Equipment, the parties will work together in good 
          faith to establish such legal presence so as to be able to enter into 
          an Equipment Schedule in such country.
     
     5.5  OTHER EQUIPMENT.  In the event SABRE shall elect to exercise its right
          to include other equipment (such as midrange, PC's, or
          telecommunications equipment) under the terms of this Agreement, SABRE
          shall notify Comdisco at least sixty (60) days prior notice and
          provide a list of other equipment that shall be included under the
          Agreement.  In such event, the parties shall meet in good faith to
          agree on the Minimum Commitment Period, Monthly Rental, Funding Factor
          and Equipment Cost for such other equipment, as well as

          the Refresh Pool credit for such other equipment.  Any other 
          equipment initially included in such election shall be deemed as 
          SABRE Equipment under this Agreement.

     5.6  SHORT-TIME PROCUREMENTS.  Comdisco understands that from time to time
          and under certain circumstances SABRE must act on a shorter timeframe
          than has been determined to be necessary under this Agreement. 
          Notwithstanding any timeframe by which Comdisco is allowed to respond,
          or SABRE is required to give notice under this Agreement or any
          Operative Agreement, if in SABRE's commercially reasonable business
          judgement, SABRE is required to shorten or not comply with such
          timeframe due to an event of operational necessity or emergency, then
          SABRE shall have the right to operate its business in its best
          interest and any Refresh Equipment or Growth Equipment acquired or any
          other action taken shall not affect the right of SABRE to include such
          Equipment under the Program or delete such Equipment from the Program,
          and SABRE shall have the right to include or delete such Equipment as
          if such notice had been given or time had elapsed.
     
     5.7  RELOCATION OF EQUIPMENT. SABRE shall, at its own risk, cost, and
          expense, have the right to relocate the Equipment from the location
          stated in the applicable United States or Non-U.S. (as the case may
          be) Equipment Schedule to other locations as follows:  a) if SABRE
          wishes to relocate the Equipment to another country and be relieved of
          its obligations as lessee under the applicable Equipment Schedule for
          such Equipment, then SABRE may move the Equipment outside of the
          United States or foreign country by terminating and removing the
          Equipment from its existing Equipment Schedule and adding it to an
          existing Equipment Schedule for the country where the Equipment is to
          be relocated (or if none exists, under a new Equipment Schedule for
          such country) with SABRE or the applicable local SABRE affiliate for
          that country for an Initial Term equal to the remainder of the
          original Initial Term and for a Monthly Rental which is equivalent to
          the current Monthly Rental for such Equipment with local currencies
          and interest rates being considered; or b) if SABRE wishes to relocate
          the Equipment to another country or within the country in which the
          Equipment was originally located, then SABRE may move the Equipment
          outside of the United States or foreign country or within the country,
          provided, however, that (i) no such relocation relieves SABRE of its
          obligation under the applicable Equipment Schedule, and (ii) upon the
          expiration or termination of the Equipment Schedule, SABRE returns the
          Equipment to the country where the Equipment was originally installed
          (unless otherwise agreed to by Comdisco).  Whether SABRE elects a) or
          b), SABRE shall pay any reasonable and actual additional costs and
          expenses (including property taxes, sales and use taxes, and customs
          and duties (including import and export taxes), but no other taxes
          except those described in Section (iii) below) resulting from such
          relocation, and (iii) SABRE may move the Equipment outside the United
          States or foreign country (as the case may be) only after giving 
          Comdisco written notice (addressed to the Director of Taxes), at 
          least thirty (30) days prior to the date such Equipment is to be 
          moved; that SABRE intends to move the Equipment outside the United 
          States or foreign country.  If, within twenty-one (21) days of receipt
          of such notice, Comdisco delivers written notice to SABRE (addressed 
          to the Project Manager as defined under this Agreement) certifying 
          that moving the Equipment outside the United States or the foreign

          country would have an adverse impact on Comdisco's federal income tax
          liability or on any other tax liability other than property taxes,
          sales and use taxes, and customs and duties (including import and
          export taxes), then SABRE may (x) keep the Equipment in the United
          States or the foreign country, (y) move the Equipment outside the
          United States or foreign country if it agrees to return the Equipment
          to the country where the Equipment was originally installed (unless
          otherwise agreed to by Comdisco) and to indemnify Comdisco, on terms
          reasonably acceptable to Comdisco for (a) any increase in Comdisco's
          federal tax liability and (b) such other taxes, if any, that the
          parties agree to, based on good faith negotiation, or (z) remove the
          Equipment from the Equipment Schedule in accordance with the Refresh
          Pool Mechanics described in the Agreement.  SABRE shall provide to
          Comdisco written notice of all relocations performed within the
          country in which the Equipment was originally installed.  In the event
          of a relocation as specified in (a) above, the portion of the Refresh
          Pool set out in the Equipment Schedule for which the Equipment is
          being terminated and removed shall be decreased as provided in the
          Refresh Pool Mechanics in Section 4.4(c), and the portion of the
          Refresh Pool set out in Equipment Schedule to which the Equipment is
          being added shall be increased as provided in the Refresh Pool
          Mechanics in Section 4.4(c).  The Minimum Commitment Period for such
          Equipment shall not change due to such relocation.
     
     5.8  RECONFIGURATION.  Upon prior written notice to Comdisco, SABRE may
          reconfigure and install Attachments on the Equipment.  In the event of
          such a Reconfiguration or Attachment which SABRE has purchased and
          retained ownership of, SABRE shall, upon return of the Equipment, at
          its expense, restore the Equipment to the original configuration
          specified on the Equipment Schedule or a "higher level configuration"
          in accordance with the manufacturer's specifications and in the same
          operating order, repair and appearance as when installed (normal wear
          and tear excluded).  For purposes hereof, "higher level configuration"
          means (a) an equal or better configuration with respect to main
          memory, cache channels or other features, and of the same manufacturer
          as the original configuration, and (b) that such upgrades will have
          megabyte capacity for DASD and Tape, and a MIPS rating for processors
          that is equal or higher than the original capacity and of the same
          manufacturer as the original configuration.  In the event of such a
          Reconfiguration or Attachment which SABRE has financed with Comdisco
          as provided for below, SABRE shall return the Equipment with such
          Reconfiguration or Attachment. If any parts are removed from the
          Equipment during the Reconfiguration or Attachment, the restoration
          shall include, at SABRE's option, the installation of either the
          original removed parts or Like Parts.  Alternately, with Comdisco's
          prior written consent which shall not be unreasonably withheld, SABRE
          may return the Equipment with any Attachment or upgrade.  If any parts
          of the Equipment are removed during a Reconfiguration or Attachment,
          Comdisco may require SABRE to provide additional security, reasonably
          satisfactory to Comdisco and SABRE, in order to ensure performance of
          SABRE's obligations set forth in this subsection.  Neither Attachments
          nor parts installed on Equipment in the course of Reconfiguration nor
          software, applications or data installed by SABRE shall be required to
          be returned with the Equipment.  The Manufacturer or Maintenance
          Organization may incorporate engineering changes, safety changes, or
          make temporary alterations to the Equipment.  All items returned to

          Comdisco with the Equipment, except software, applications or data not
          owned by Comdisco shall become the property of Comdisco. For purposes
          of this subsection, "Attachment" means any accessory, equipment or
          device and the installation thereof that does not impair the original
          function or use of the Equipment and is capable of being removed
          without causing material damage to the Equipment and is not an
          accession to the Equipment; "Like Part" means a substitute part which
          is lien free and of the same manufacturer and part number as the
          removed part, and which when installed on the Equipment shall be
          eligible for maintenance coverage with the Manufacturer of the
          Equipment; "Reconfiguration" means any change to the Equipment that
          would upgrade or downgrade the performance capabilities of the
          Equipment in any way.   
     
          However, if at the time of the Reconfiguration such Reconfiguration
          (i) is not capable of being removed without causing material damage to
          the Equipment; or (ii) if at the time of the Reconfiguration the
          Manufacturer does not offer on a commercial basis a means for the
          removal of the additonal items; then such Reconfiguration is subject
          to the prior written consent of Comdisco, which shall not be
          unreasonably withheld.  Notwithstanding the above, if such
          Reconfiguration is included as Growth or Refresh Equipment under this
          Agreement and the Operative Agreements, then Comdisco's consent to
          such Reconfiguration is not required. Notwithstanding anything to the
          contrary contained herein, for any upgrades, attachments and
          modifications comprising such Reconfiguration or Attachment or
          otherwise added (whether new or used) to any Equipment leased by SABRE
          under an Equipment Schedule, SABRE shall have the right to purchase
          and retain ownership of any such upgrades, attachments and
          modifications, or finance any such upgrades, attachments and
          modifications with Comdisco.  In no event shall SABRE have the right
          to finance any such upgrades, attachments and modifications with a
          party other than Comdisco.  In addition, SABRE shall provide Comdisco
          any commercially reasonable opportunity to supply any such upgrades,
          attachments and modifications to the Equipment leased under an
          Equipment Schedule that are available in the used marketplace.
     
     5.9  CPU GENERATIONAL UPGRADES.  In the event SABRE elects to add a CPU
          Generational Upgrade to an item of Equipment under this Program, such
          CPU Generational Upgrades shall be added to the Program and the
          following events will occur:

               Notwithstanding the above, any item of Equipment can be upgraded
               using the CPU Generational Upgrade mechanics as described above
               no more than once every [TEXT OMITTED - CONFIDENTIAL TREATMENT

               current Minimum Commitment Period for that Equipment.
          
     5.10 SUBLEASE.  Provided all amounts then due and owing (other than a
          Disputed Amount) are paid by SABRE, SABRE shall be entitled without
          Comdisco's consent to sublease any or all of the Equipment, or any
          part thereof, to, or permit their use by, any person or entity (except
          to an entity affiliated with the Manufacturer of such Equipment),
          including without limitation any subsidiary or affiliate of SABRE,
          incorporated and located in the United States of America, but in all
          cases only upon and subject to terms and conditions at least as
          restrictive as those contained in this Agreement.  No such sublease or
          assignment shall relieve SABRE of any liability or obligations
          hereunder except if Comdisco consents, in writing, based upon the
          credit-worthiness of such sublessee or assignee and the terms and
          conditions of the assignment or sublease, which consent shall not be
          unreasonably withheld or delayed, to relieve SABRE of such obligation.
          SABRE's rights under this Section are subject to Comdisco's right to
          match any sublease proposed by a third party (except one proposed by
          any subsidiary, affiliate or outsourcing Customer of SABRE).  Except
          for offers from subsidiaries, affiliates or outsourcing Customers of
          SABRE, SABRE shall provide Comdisco with the terms of the third party
          offer and Comdisco shall have three (3) days to match the offer and
          SABRE shall sublease the Equipment to Comdisco if Comdisco has timely
          matched the third party offer. 

6.   MAINTENANCE AND REPAIRS

     6.1  EQUIPMENT CONDITION.  SABRE shall, during the Initial Term or any
          Extension Period, at its own expense, keep the Equipment in good
          working order and condition and make all necessary adjustments,
          repairs, and replacements thereto, reasonable wear and tear excepted. 
          SABRE shall not use or permit the Equipment to be used for any purpose
          for which the Equipment is not reasonably suited.

<PAGE>

     6.2  MAINTENANCE CONTRACT.  SABRE may, during the Initial Term or any
          Extension Period, at its own expense, enter into a maintenance
          contract with the Manufacturer or a Maintenance Organization selected
          by SABRE, or may provide for maintenance itself.  SABRE is at all
          times responsible for maintenance of the Equipment.



7.   EQUIPMENT RETURN

     7.1  PURCHASE RIGHTS.  At the termination or early termination of an
          Equipment Schedule as provided for herein, SABRE shall have the option
          to tender to Comdisco or its carrier at the Equipment location for
          return to Comdisco the same serial numbered Equipment listed on such
          Equipment Schedule.  In addition, at the termination or early
          termination of an Equipment Schedule, upon SABRE's notice at least
          sixty (60) days prior to such termination, SABRE shall have the right
          to elect to purchase the Equipment.  The parties shall meet personally
          or telephonically to attempt to agree, in good faith, on the Fair
          Market Value for the Equipment.  In the event the parties fail to
          agree on the Fair Market Value for the Equipment within five (5) days
          of such notice provided above, then the parties shall engage the
          appraisal process described in Section 1.24.  [TEXT OMITTED - 
          CONFIDENTIAL TREATMENT REQUESTED].  Upon pick up of SABRE owned 
          Replacement Equipment by Comdisco or its carrier, SABRE shall transfer
          ownership of the Replacement Equipment to Comdisco, and Comdisco 
          shall transfer ownership for the Equipment being replaced to SABRE.  
          At least ninety (90) days prior to the expiration of the Initial 
          Term, Comdisco agrees to provide SABRE with notice that SABRE's 
          notices shall be due to terminate the Equipment Schedule and either 
          return the Equipment or purchase the Equipment.  If SABRE elects to 
          terminate the Equipment Schedule, then the Equipment Schedule shall 
          terminate in accordance with Section 3 herein.  If SABRE elects to 
          purchase the Equipment and if SABRE (i) fails to provide such notice 
          to Comdisco in the time frame indicated, or (ii) a) provides such 
          notice to Comdisco but fails to purchase the Equipment for a mutually 
          agreed upon Fair Market Value within three (3) days following the end 
          of such term or any extension, and b) fails to make available for 
          pick up by Comdisco or its carrier the Equipment or Replacement 
          Equipment if the parties are unable to agree upon a Fair Market Value 
          within ten (10) days following the end of such term or extension, then
          the Equipment Schedule shall continue in full force and effect as 
          provided for in Section 3, retroactive to the date of termination or 
          early termination until

<PAGE>

          such time as the conditions listed in (i) or (ii) are met.  
          Notwithstanding the foregoing, upon the termination or early 
          termination of an Equipment Schedule, SABRE shall have the right to 
          make available for pick up by Comdisco or its carrier for return to 
          Comdisco Replacement Equipment in lieu of items of personal 
          computer Equipment provided it is understood that whether SABRE 
          returns items of personal computer Equipment or items of personal 
          computer Replacement Equipment, Comdisco shall process the return 
          based on the number of units returned per location and shall not 
          process the return by serial number.  
          [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED].

          Notwithstanding the foregoing, in the event the Initial Term has
          expired and the Equipment Schedule has continued on a month to month
          basis, in the event Comdisco provides SABRE with notice to terminate,
          SABRE shall have the right to provide notice within two (2) business
          days of receiving such notice that it elects to purchase the
          Equipment.  In the event of such election, Comdisco's right to
          terminate shall not be in effect for sixty (60) days to allow for the
          procedure set forth in this Section 7 to occur.  In the event the
          parties do not reach agreement for SABRE to purchase the Equipment,
          SABRE shall give notice to terminate such Equipment Schedule as
          provided for in Section 3 above.

          Upon Termination for Convenience of the Agreement or an applicable
          Equipment Schedule, as provided herein or in the Operative Agreements,
          the time provided in this provision shall be extended to provide an
          orderly winddown and return or purchase of Equipment, as may
          reasonable and necessary and not to exceed six (6) months as per
          Section 3.4 herein.

     7.2  CONDITION OF EQUIPMENT.  The Equipment and/or Replacement Equipment
          returned to Comdisco, shall at the time it is disconnected from its
          then location, be in the same condition and working order as when
          delivered to SABRE, reasonable wear and tear excepted, and shall be
          certified eligible for maintenance by the Manufacturer.  In addition,
          the Equipment shall be at the then current Manufacturer's release,
          revision and engineering change levels which were provided to SABRE by
          the Manufacturer at no cost throughout the Initial Term or any
          Extension Period under the Manufacturer's standard maintenance
          contract.  Notwithstanding the foregoing, in the event SABRE uses a
          party other than the Manufacturer to maintain the Equipment, the
          Equipment shall be at the then current Manufacturer's release,
          revision and engineering changes levels which would have been provided
          to SABRE by the Manufacturer at no cost throughout the Initial Term or
          any Extension Period had SABRE entered into a standard maintenance
          contract with the Manufacturer.  SABRE shall at its expense, have the
          Equipment deinstalled and certified by the Manufacturer, and packed in
          accordance with the Manufacturer's guidelines.
     
     7.3  REQUIREMENTS FOR RETURN OF EQUIPMENT.  If Comdisco is no longer
          providing Services under the Program, then SABRE and Comdisco will
          appoint a principal contact person

<PAGE>

          (the "Contact") with responsibility for coordinating delivery and 
          return of Equipment to one centralized shipping location.  SABRE's 
          Contact will provide Comdisco ten days written notice of the 
          Equipment's availability for pick-up, but in no event prior to 
          SABRE's notice of termination pursuant to Section 3 and/or 7 of this 
          Agreement.
     
          Comdisco will make arrangements for its transportation carrier to
          contact SABRE's Contact to coordinate the return of the Equipment. 
          Comdisco's transportation carrier will be responsible for packing
          Distributed Systems Equipment on site on the Pick Up Date.  Risk of
          loss for all Equipment shall pass to Comdisco once the Equipment has
          been tendered to Comdisco or its carrier for return at the Equipment
          location.
     
          SABRE will be responsible, and will be invoiced, for any damaged,
          non-functional and/or missing Equipment or Equipment parts based on
          its Fair Market Value at the time the Equipment is tendered to
          Comdisco or its carrier for return.
     
8.   ASSIGNMENT
     
     8.1  ASSIGNMENT OF MONTHLY RENTAL.  The terms and conditions of each
          Equipment Schedule have been fixed by Comdisco in order to permit
          Comdisco to assign its right to receive the Fixed Equipment Portion of
          the Monthly Rental, subject to SABRE's interest herein, and grant a
          security interest in each Equipment Schedule and/or the Equipment to a
          non-affiliated third party ("Assignee") for purposes of securing
          nonrecourse financing, subject to SABRE's rights hereunder and under
          the Operative Agreements [TEXT OMITTED - CONFIDENTIAL TREATMENT 
          REQUESTED].  [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED].  
          [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED]. Any such Assignee 
          shall agree in writing that (a) it will only further assign the Fixed 
          Equipment Portion of the Monthly Rental to an entity which is (i) 
          "investment grade" (as defined below); (ii) not a competitor of SABRE;
          (iii) not currently involved with litigation with SABRE; and (iv) such
          entity agree to these same limits to its right to further assign; 
          (b) Assignee shall not disturb SABRE's quiet use and enjoyment of the 
          Equipment so long as SABRE is not in default (and after such 
          applicable cure period) of the payment of the Fixed Equipment Portion 
          of the Monthly Rental so assigned; and (c) SABRE's costs, 
          obligations, liability and risks shall not be increased nor its 
          rights or benefits diminished as a result of such assignment. 
          However, any such assignment by Comdisco shall not relieve Comdisco of
          its obligations to SABRE, and shall not change SABRE's duties or
          increase the burden, except as specifically provided for herein and in
          the Operative Agreements or risks imposed on SABRE, except change
          SABRE's obligation to pay the Assignee. Notwithstanding, SABRE shall
          have the option to pay directly to Comdisco such assigned amounts in
          lieu of paying the Assignee directly,

<PAGE>

          in which case Comdisco shall indemnify SABRE from and against any 
          loss or damage (i) due to the failure of Comdisco to pay such 
          assigned amounts to the Assignee, or (ii) for any late payment 
          charges due to Comdisco's failure to pay such Assignee in a timely 
          manner. Further, SABRE shall acknowledge such assignments in a 
          written notice which shall be given by Comdisco to SABRE thirty (30) 
          days prior to the date SABRE is required to make payments to the 
          Assignee.  SABRE also agrees that: (a) the Assignee shall be entitled 
          to exercise all of Comdisco's rights, but shall not be obligated to 
          perform any of the obligations of Comdisco, provided that Assignee 
          agrees to release any security interest in any Equipment if and to 
          the extent required in connection with SABRE's exercise of SABRE's 
          rights with respect to such Equipment; (b) the Assignee shall not 
          disturb SABRE's quiet and peaceful possession and unrestricted use
          of the Equipment so long as SABRE is not in default (and such default
          remains uncured during the cure period) and the Assignee continues to
          receive  the Fixed Equipment Portion of the Monthly Rental so assigned
          payable under the Equipment Schedule; (c) SABRE shall pay all of the
          Fixed Equipment Portion of the Monthly Rental so assigned (subject to
          any withholding required by law, for purposes of this Section only) 
          to the Assignee  subject to SABRE's rights hereunder and under the
          Operative Agreements despite any defense or claim which it has against
          Comdisco (SABRE reserves its rights to have recourse directly against
          Comdisco for any defense or claim); and (d) subject to and without
          impairment of SABRE's leasehold rights in the Equipment, SABRE holds
          the Equipment for the Assignee to the extent of the Assignee's rights
          in that Equipment.  For purposes hereof, "investment grade" shall be
          defined as any of the following:  (1) a US Bank Domestic Long Term
          Deposits Rating of Baa3 or better as published in Moody's Bond Record,
          (2) a senior Corporate Credit Rating of Baa3 or better as published in
          Moody's Bond Record, or (iii) a senior credit rating by another rating
          agency other than found in Moody's Bond Record that is considered
          "investment grade" in the domestic financial community.  In the event
          there are ratings found in Moody's Bond Record and another rating
          agency, the Moody's rating shall prevail.
     
     8.2  OTHER ASSIGNMENTS.  Except for Comdisco's rights under Section 8.1
          above, no part of this Agreement may be assigned directly or
          indirectly, by Comdisco without SABRE's prior written approval, which
          may be withheld in its sole discretion. Comdisco shall notify SABRE in
          writing, and SABRE may immediately terminate this Agreement and the
          Operative Agreements without liability therefor, if Comdisco dissolves
          or is liquidated.  SABRE may assign this Agreement to its Affiliates
          or any successor in interest to all or any part of SABRE's operations,
          without Comdisco's consent, so long as (i) such assignee's credit
          standing is equal to or better than SABRE's credit standing, but not
          less than "Investment Grade" and (ii) the assignee agrees in writing
          to be bound by the terms and conditions of this Agreement and the
          applicable Operative Agreements.  If the assignee's credit standing is
          less than Investment Grade, then such assignment shall be subject to
          the prior written consent of Comdisco and may result in a change in
          Monthly Rental.  SABRE shall not act as a guarantor of the assignee's
          obligations under this Agreement.

9.   OWNERSHIP - TITLE
     
     9.1  COMDISCO WARRANTY.  Comdisco warrants that, as of the Commencement
          Date of each Equipment Schedule and throughout the term thereof,
          Comdisco shall have good and valid title to, or the power and
          authority to lease, the Units leased pursuant to such Equipment
          Schedule.  Nothing contained in this Agreement or any Equipment
          Schedule shall give or convey to SABRE any right, title or interest in
          or to any Unit, except for the leasehold interest and other rights set
          forth in the terms of this Agreement and the applicable Equipment
          Schedule.  SABRE does not indemnify Comdisco or any third party from
          any claims, actions, suits, proceedings, costs, expenses, damages, or
          liability at law or in equity, including attorney's fees arising out
          of, connected with, or resulting should this Agreement or associated
          transaction(s) be deemed to be other than a true lease. Comdisco shall
          indemnify SABRE for any loss or damage due to a breach of Comdisco's
          warranty of quiet use and enjoyment of the Equipment that arises as a
          result of any encumbrance placed on the Equipment by or through
          Comdisco.  
     
     9.2  SABRE OBLIGATIONS.  Except for any claim arising from the acts,
          omissions, or negligence of Comdisco, SABRE shall at its own expense
          protect and defend the respective interests in the Equipment of
          Comdisco against all persons claiming against SABRE, at all times keep
          the Equipment free and clear from any legal process or other
          encumbrance arising by or through SABRE, give Comdisco prompt written
          notice thereof and indemnify Comdisco from any loss caused by such an
          encumbrance.
     

     9.3  COMDISCO INSPECTION.  Comdisco or its agent shall have reasonable
          access to the Equipment during reasonable business hours for the
          purpose of inspection, provided however, that SABRE has been notified
          in writing at least ten (10) business days in advance and SABRE has
          agreed to the time and date of access.  While on SABRE's premises,
          Comdisco and its agents shall observe all security regulations, as
          well as rules and procedures governing conduct as SABRE require.  The
          inspection of Equipment is a physical inspection only, Comdisco shall
          not review SABRE's data nor log onto SABRE's system, during such
          inspection.

     9.4  NOTICE OF DAMAGE.  SABRE shall promptly notify Comdisco of all details
          concerning any material damage or loss arising out of the improper
          manufacture, functioning or operation of the Equipment.

10.  WARRANTIES
     10.1 ENFORCEMENT.  At the request and expense of SABRE, Comdisco shall, at
          SABRE's option: (1) enforce for the benefit of SABRE any rights which
          Comdisco may enforce against the Equipment Manufacturer or supplier of
          Comdisco with respect to the Equipment, including but not limited to
          remedies, if any, provided by the Manufacturer or the supplier of
          Comdisco for breach of warranty or patent, copyright or trade secret
          infringement or otherwise, and remedies and/or recovery of damages
          otherwise provided by law or in equity and/or any recovery of refunds
          or price adjustments or other claims arising under the equipment
          purchase contract; or (2) to the extent assignable, make a full or
          partial assignment to SABRE, as SABRE shall request, of any such
          rights described above enforceable by Comdisco against the Equipment
          Manufacturer or supplier of Comdisco with respect to the Equipment.

     10.2 WARRANTY AND DISCLAIMER.  Except as to warranty of title or as
          otherwise specifically provided herein or in the Agreement, COMDISCO
          SUPPLIES THE EQUIPMENT AS IS AND NOT BEING THE MANUFACTURER OF THE
          EQUIPMENT, MAKES NO WARRANTY OR REPRESENTATION, EITHER EXPRESS OR
          IMPLIED, AS TO THE EQUIPMENT'S MERCHANTABILITY, FITNESS FOR A
          PARTICULAR PURPOSE, OR AS TO PATENT INFRINGEMENT OR THE LIKE, it being

11.  INSURANCE AND RISK OF LOSS.

     11.1 RISK OF LOSS; SABRE'S OBLIGATIONS TO MAINTAIN INSURANCE.  Beginning on
          the Delivery Date and continuing until the Equipment is tendered to
          Comdisco or its carrier at the Equipment location for return to
          Comdisco, SABRE relieves Comdisco of responsibility for all risks of
          physical damage to, or loss or destruction of, the Equipment while in
          SABRE's possession.  During the term of lease as to each Equipment
          Schedule, SABRE shall at its own expense keep in effect public
          liability insurance in amounts and against risks customarily insured
          against by SABRE on equipment owned by it, and property damage
          insurance covering the Equipment designated in such Equipment Schedule
          for an amount not less than its Casualty Value.  All policies for
          property damage insurance shall list Comdisco and its Assignee as
          additional insured and loss payee, and shall provide for at least
          thirty (30) days prior written notice to Comdisco of cancellation or
          expiration.  Evidence of such insurance coverage shall be furnished to
          Comdisco upon demand.  Notwithstanding the foregoing provisions,
          provided SABRE is Investment Grade, or if SABRE's credit standing is
          not rated or implied by an independent rating agency, the credit
          quality of SABRE is reasonably deemed by Comdisco to be "Investment
          Grade", SABRE may elect to self-insure with respect to damage to the
          Equipment or third party personal and property damage, or both
          provided that such self-insurance is consistent with SABRE's normal
          business practices with respect to other similar equipment it leases,
          rents, or owns.

     11.2 DAMAGE TO EQUIPMENT.  If any Unit is rendered unusable as a result of
          any physical damage to, loss, or destruction of the Unit, SABRE shall
          give Comdisco prompt notice thereof and the applicable Equipment
          Schedule shall continue in full force and effect without any abatement
          of rental fees.  SABRE shall attempt to determine, within thirty (30)
          days after the date of occurrence of such loss, damage, or
          destruction, whether such Unit can be repaired.  In the event SABRE
          determines that such Unit can be repaired, SABRE, at its expense,
          shall cause such Unit to be promptly repaired; or in the event SABRE
          determines that the Unit was lost or cannot be repaired, SABRE shall,
          at Comdisco's option, either: (1) at its expense, promptly replace
          such Unit if available, with Equipment which is lien free and of same
          manufacture, model, and features as the lost, damaged, or destroyed
          Unit and convey title to such replacement to Comdisco free and clear
          of all liens and encumbrances, and the applicable Equipment Schedule
          shall continue in full force and effect as though such loss, damage,
          or destruction had not occurred; or (2) terminate the applicable
          Equipment Schedule with respect to such Unit and pay Comdisco an
          amount equal to the Casualty Value indicated in the applicable
          Equipment Schedule as of the date of the loss, damage, or destruction
          of the Unit.
     
     11.3 COMDISCO'S OBLIGATION TO MAINTAIN INSURANCE.  
          a)   For the Services provided under this Agreement and the Operative
               Agreements, Comdisco shall procure at its own expense and
               maintain in full force and effect during the term of the
               Agreement, policies of insurance with the types and the minimum
               amounts of coverage stated below.  The policies shall be with
               responsible insurance carriers duly qualified in the
               jurisdictions in which the products and services are to be
               delivered and performed, and shall cover the operations and
               obligations of Comdisco under the Agreement.

          b)   Except for Worker's Compensation, Errors and Omissions Coverage,
               and Employer's Liability, SABRE shall be named as an additional
               insured in such policies and they shall contain standard cross
               liability clauses.  Comdisco shall cause the liability it assumed
               under this Agreement to be specifically insured under the
               contractual liability section of the liability insurance
               policies.  The liability policy shall be primary without right of
               contribution from any insurance by SABRE.  Such policies shall
               require that SABRE be given not less than thirty (30) days prior
               written notice of any material change or cancellation therein.

          c)   Comdisco shall provide SABRE with certificates of insurance
               evidencing all of the above coverage, including all special
               requirements specifically noted above.  Comdisco shall provide
               SABRE with certificates of insurance evidencing material changes,
               renewal or substitution of such insurance thirty (30) days prior
               to the effective date of same.

          d)   The provisions herein as to maintenance of insurance shall not be
               construed as limiting in any way the extent to which Comdisco may
               be held liable for payment for damages to persons or property
               resulting from its activities under the Agreement, the activities
               of any it its employees, or other person(s) for which Comdisco is
               otherwise responsible shall maintain throughout the term of this
               Agreement insurance coverage for itself.

               Breach" shall mean (i) a breach of SABRE's or SABRE's Customer's
               Confidential Information in a manner which has caused or could
               cause substantial harm to SABRE or SABRE's Customer; (ii)
               Comdisco's total or substantial failure to perform the Services

               acquisition of Growth and Refresh Equipment and to Swap Events,

               services itself or through a third party; (iv) chronic failure to
               pay Third Party Leases (which is the failure to make [TEXT 
               OMITTED - CONFIDENTIAL TREATMENT REQUESTED] or more monthly 
               payments over the prior [TEXT OMITTED - CONFIDENTIAL TREATMENT 
               REQUESTED] ([TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED]) 
               months) which failures were cured during the applicable cure 
               period; (v) failure to pay Third Party Leases which failure is 
               continuing after the applicable cure period; (vi) Breach of 
               SABRE's quiet use and enjoyment of the Equipment by Comdisco or 
               its Assignee or (vii) Comdisco:
     
               A.   ceases to do business as a going concern;
               B.   makes a general assignment for the benefit of, or enters
                    into any arrangement with creditors in lieu thereof;
               C.   is unable or admits in writing its inability to pay its
                    debts as they become due;

               E.   authorized, applies for, or consents to the appointment of a
                    trustee or liquidator of all or a substantial part of its
                    assets or has proceedings seeking such appointment commenced
                    against it which are not terminated within 60 days after
                    such commencement;
               F.   files a voluntary petition under any bankruptcy or
                    insolvency laws or files a voluntary petition under the
                    reorganization or arrangement provisions of the laws of the
                    United States pertaining to bankruptcy or any similar law of
                    any jurisdiction or has proceedings under any such law
                    instituted against it which are not terminated within 30
                    days after such commencement; or
               G.   has any substantial part of its property become subject to
                    any levy, seizure, assignment or sale for or by any creditor
                    or governmental agency without said, levy, seizure,
                    assignment or sale being released, lifted, reversed or
                    satisfied within 10 days thereafter.
     
               In the event of a Substantial Material Breach under (i), (ii),

               Comdisco's Termination Fee as described above and pursue any
               other right or remedies against Comdisco; provided, however, in
               the event of a Substantial Material Breach under (ii), Comdisco's
               liability to SABRE arising from the pursuit of any other right or
               remedies shall not in any event

               In the event of a Substantial Material Breach under (iii), (iv)
               or (v) above SABRE shall be entitled, [TEXT OMITTED - 
               CONFIDENTIAL TREATMENT REQUESTED]. 
     
               SABRE further agrees that it will not exercise its right
               hereunder until it has complied with Section 12.4 below.
     
               Comdisco shall not be considered in Substantial Material Breach
               of (ii) above in the event SABRE shall fail to perform its
               obligations under the Services Schedule (referred to as Schedule
               1) and as a result of such failure, Comdisco is unable to perform
               its obligations thereunder.  In the event of SABRE's total or
               substantial failure to perform its obligations under the Services
               Schedule, Comdisco shall (after such thirty (30) day notice and
               opportunity to cure) have the right to terminate its obligations
               to provide such Asset Management Services without further
               obligation or liability with respect thereto and the Monthly
               Rental shall be reduced as provided for under such Services
               Schedule.
     
          (b)  Subject to the provisions of Section 12.4, Comdisco shall be in
               default and there shall be a material breach of this Agreement if
               Comdisco fails to perform any of its material obligations herein,
               including, but not limited to, its obligations under Sections 12,
               14 and 15 and such failure shall continue uncured for thirty days
               after written notice thereof to Comdisco by SABRE.  Except as
               expressly limited herein or an Operative Document, in the event
               of Comdisco's default hereunder, SABRE's remedies shall not be
               limited to the remedies specifically provided in this Agreement
               but shall be in addition to any rights or remedies provided by
               any other Operative Agreement, or by law or equity including
               reasonable attorney's fees, provided, however, that it is the
               understanding of the parties that, subject to the terms of this
               Agreement, except for a violation of Comdisco's warranty of quiet
               use and enjoyment as set forth in Section 14 hereof, no default
               by Comdisco, or the exercise of the remedies provided for herein
               by SABRE shall relieve SABRE of its obligations to make payments
               of Monthly Rental except as provided herein.  The waiver by SABRE
               of any breach of any obligation of Comdisco shall not be deemed a
               waiver of such obligation or of any subsequent breach of the same
               or any other obligation.
     
     12.4 INADVERTENT FAILURE TO PERFORM.  Both parties recognize that due to
          the complex structure of this transaction that there may be times that
          a party is in inadvertent default under the terms of this Agreement
          and/or the Operative Agreements despite their good faith efforts to
          comply to all of such terms and conditions.  Therefore,
          notwithstanding anything contained herein both parties hereby agree
          that they will not exercise their remedies provided for in this
          Agreement or Operative Agreement, or place the other party in default
          hereunder, if in their good faith commercially reasonable business
          judgment a default is

<PAGE>

          due to an inadvertent failure to perform on the part of the other 
          party.  The parties further agree that prior to exercising any rights 
          of termination arising out of a default granted under this Agreement 
          or any of the Operative Agreements, that they will proceed through 
          Level Three of the Dispute Resolution Process but not including Court 
          as outlined in Section 13 herein, and make a good faith effort to 
          settle the dispute in that manner.
     
13.  DISPUTE RESOLUTION PROCESS
     13.1 RESOLVE DISPUTES.  Except as indicated below, in the event of
          disputes, controversies or claims arising under this Agreement
          (including disputes as to the existence of any breach of this
          Agreement which would give rise to a right to terminate this Agreement
          or right or obligations of a party hereunder or under an Operative
          Agreement) (each, a "Dispute"), the parties shall (unless otherwise
          provided in this Agreement or the Operative Agreements) resolve
          Disputes in accordance with this Section.  Notwithstanding this
          Section or any other provision of this Agreement nor the Operative
          Agreements, the parties agree that the fact that either party may take
          action without resorting to dispute resolution when it believes it is
          in its best interests to safeguard its business operations or assets
          and shall not, in and of itself, constitute a breach of this
          Agreement. 
     
     13.2 ESCALATION PROVISION.  SABRE and Comdisco agree to utilize the
          following procedures to resolve Disputes:
          (a)  LEVEL ONE.  If either party identifies a Dispute that requires
               resolution, it will give prompt written notice thereof to the
               other party's Project Manager.  The Project Managers will then
               negotiate in good faith on a regular and frequent basis to
               resolve the Dispute as expeditiously as feasible.  If the Project
               Managers are unable to resolve the Dispute within 10 days the
               Project Managers will refer the Dispute to a Vice President of
               SABRE and a Vice President of Comdisco (the "Vice Presidents"),
               and each Project Manager will provide to both Vice Presidents a
               written statement (a "Dispute Statement") describing in detail
               his or her position related to the Dispute.
          
          (b)  LEVEL TWO.  Promptly after receiving the Dispute Statements, the
               Vice Presidents will negotiate in good faith on a regular basis
               to resolve the Dispute as expeditiously as feasible.  If the Vice
               Presidents are unable to resolve the Dispute within 15 days,
               either Vice President may state in writing to the other that they
               will not be able to resolve the remaining Dispute through
               continued negotiation.  Promptly thereafter, each Vice President
               will refer the Dispute to a Sr. Vice President of SABRE and the
               Sr. Vice President of Comdisco, or if no longer such a title, the
               equivalents of such (the "Officers") and each party's respective
               management team will prepare any revisions to their respective
               Dispute Statements.  Both of the Dispute Statements, as revised,
               will be submitted to each of the Officers.

          (c)  LEVEL THREE.  Promptly after receiving the revised Dispute
               Statements, the Officers will negotiate in good faith on a
               regular and frequent basis to resolve the Dispute within 20 days.
               Either party may submit any issues that remain unresolved to a
               court of competent jurisdiction ("Court").

     13.3 GENERAL RESOLUTION PROCEDURES.
          (a)  SABRE and Comdisco agree that they will refrain from referring
               the Dispute to a Court, and no Court shall be competent to
               address any Dispute properly addressed in this fashion, until
               either party's Officer provides a written notice to the other
               that he or she has concluded in good faith that amicable
               resolution through continued negotiation of the Dispute does not
               appear likely after the conclusion of the Level Three resolution
               process described above.
          (b)  The purpose of preparing and submitting the Dispute Statements
               described above is to facilitate the resolution process. 
               However, the Dispute Statements will not limit either party from
               identifying any additional relevant issues during the resolution
               process, nor will the Dispute Statements constitute a waiver of,
               or prejudice or limit either party's rights or remedies with
               respect to, the issue(s) addressed therein. 

     14.  QUIET ENJOYMENT 
     Comdisco hereby agrees and covenants that unless and until Comdisco
     actually terminates an applicable Equipment Schedule or this Agreement
     pursuant to Section 12.2 hereof, SABRE is entitled to and shall be able to
     enjoy quiet possession and use of each Unit leased pursuant to an Equipment
     Schedule during the term thereof without interruption by Comdisco or any
     person claiming under or through Comdisco whether such be the holder of a
     lien or otherwise.
     
     15.  BREACH OF COVENANT OF QUIET ENJOYMENT BY COMDISCO
     Effective at any time following the Commencement Date of any Equipment
     Schedule executed pursuant to this Agreement, in the event that Comdisco or
     any person claiming under or through Comdisco shall be in default in
     respect of its covenant of quiet enjoyment under this Agreement with
     respect to any Equipment covered by an applicable executed Equipment
     Schedule, then SABRE may demand immediate replacement of the Equipment
     covered by such Schedule, in addition to any damages resulting from the
     disruption, and may in addition pursue any other remedies available at law
     or in equity including termination of this agreement.

     16.  CONFIDENTIALITY
     Each party agrees that it may disclose to the other party ("Receiving
     Party"), during the course of this Agreement, business or technical
     information of a confidential nature which has a great value to the
     disclosing party or a third party (either, a "Disclosing Party"), or which
     the Disclosing Party has a legal or operational obligation to protect from
     disclosure ("Confidential Information").  Additionally either party may
     have Confidential Information of, or obtained from, a third party Customer
     or other third parties.  Each party agrees to make a good faith effort to
     mark or otherwise identify Confidential Information as such.  Each party
     agrees not to use or disclose the Confidential Information for its own
     benefit, or for the benefit of any third party, except as may be required
     in its performance under this Agreement.  The Confidential Information
     shall not be treated as confidential if: i) it is or becomes available to
     the public without confidentiality restrictions through no unauthorized act
     of the Receiving Party and is not information which is otherwise protected
     hereunder; ii) is received from a third party who is not under an
     obligation of confidence to the Disclosing Party; or iii) is independently
     developed by employees or contractors of the Receiving Party who did not
     use the relevant Confidential Information of the other party in 

REVISED 12/04/98      SABRE GROUP, INC. AND COMDISCO, INC.                  47
                                 CONFIDENTIAL
<PAGE>

     the development.  If Confidential Information is required to be disclosed
     pursuant to a requirement of a governmental agency or law, the Receiving
     Party shall not be in breach of this Confidentiality Provision so long as
     the Receiving Party provides the Disclosing Party with timely notice of
     such requirement.

     17.  INDEMNIFICATION
     In addition to any indemnification provided for under the Operative
     Agreements, each party (the "Indemnifying Party") agrees to indemnify,
     defend and hold the other party (the "Indemnified Party"), and its
     officers, directors, employees, agents and Customers harmless from and
     against any and all liabilities, damages, losses, expenses, claims,
     demands, suits, fines or judgments, including reasonable attorney fees,
     costs and expenses incidental thereto, which may be suffered by, accrued
     against, charged to or recoverable from said parties by reason of bodily
     injuries, loss, claim, or damage or physical destruction of property
     arising out of or in connection with any negligent act, error or omission,
     or misconduct of the Indemnifying Party and its officers, directors,
     employees, subcontractors, and agents, during their performance under this
     Agreement.

     18.  FORCE MAJEURE
     Neither party shall be liable for delays or any failure to perform under
     this Agreement due to causes beyond its reasonable control. 
     Notwithstanding the above, no delay or other failure to perform shall be
     excused pursuant to this Section (i) by the acts or omissions of a party's
     subcontractors or other third persons providing products or services to
     such party unless such acts or omissions are themselves the product of a
     Force Majeure Condition (defined below); and (ii) unless such delay or
     failure and the consequences thereof are beyond the reasonable control and
     without the fault or negligence of the party claiming excusable delay or
     other failure to perform.  A "Force Majeure Condition" is defined as to
     include, but not limited to, those caused by, fire, explosion, flood or
     other natural catastrophe, governmental legislation, acts, orders, or
     regulation (which could not be known to the party prior to the delay),
     strikes or labor difficulties, to the extent not occasioned by the fault or
     negligence of the delayed party.  Any such excuse for delay shall last only
     as long as the event remains beyond the reasonable control of the delayed
     party.  However, the delayed party shall use its best efforts to minimize
     the delays caused by any such event beyond its reasonable control.  The
     delayed party must notify the other party promptly upon the occurrence of
     any such event, or performance by the delayed party will not be considered
     excused pursuant to this Section, and inform the other party of its plans
     to resume performance.

     Notwithstanding the above, even though the performance times under this
     Agreement (but not the term of the Agreement) shall be extended for a
     period of time equivalent to the time lost because of any failure to
     perform that is excusable under this Section, if any Force Majeure
     Condition prevents Comdisco from providing the Services within the
     timeframe required hereunder or under the Operative Agreements, SABRE shall
     have the right to obtain the applicable Service through another method or
     from another supplier and Comdisco shall be liable for the reasonable costs
     of the substitute Service if SABRE is required to contract for such Service
     to prevent a breach by SABRE of a SABRE contract with a third party.  In
     connection with acquiring Growth Equipment or Refresh Equipment or
     performing a Swap Event, then such Growth Equipment or Refresh Equipment or
     such Swap Equipment shall become a part of an Equipment Schedule under 

REVISED 12/04/98      SABRE GROUP, INC. AND COMDISCO, INC.                  48

     this Agreement as if it had acquired as otherwise provided herein. 
     Notwithstanding anything to the contrary contained herein SABRE shall not
     be relieved of its obligations under the Operative Agreements to make
     payments which arise during the Force Majeure event provided however SABRE
     shall not be considered in breach of the Operative Agreements if SABRE is
     unable to make such payments due to the Force Majeure event.

     19.  GENERAL
     19.1 GOVERNING LAW.  This Agreement and its Equipment Schedules shall be
          governed by and construed in accordance with the laws of the State of
          Texas.  Both parties hereby consent and submit to the jurisdiction of

          OR AN OPERATIVE AGREEMENT. 

     19.2 ADVERTISING.  Comdisco shall not use the name of or refer to SABRE or
          any of its affiliates directly or indirectly in any advertisement,
          news release or professional or trade publication without receiving
          prior written approval from SABRE.
     
     19.3 NO WAIVER.  The failure of either party at any time to require
          performance by the other party of any provision of this Agreement
          shall in no way affect that party's right to enforce such provisions,
          nor shall the waiver by either party or any breach of any provision of
          this Agreement be taken or held to be a waiver of any further breach
          of the same provision.

          be in writing and, any notices or other communications required or

     19.10  EXPORT ADMINISTRATION.  The parties agree to comply fully with all
            relevant export laws and regulations of the United States or any
            country in which an Equipment Schedule is entered into ("Export
            Laws") to assure that neither the Service nor any direct product
            thereof (1) is exported, directly or indirectly, in violation of
            Export Laws; or (2) is intended to be used for any purposes
            prohibited by the Export Laws, including, without limitation,
            nuclear, chemical or biological weapons proliferation.

     19.11  INDEPENDENT CONTRACTOR.  COMDISCO represents and warrants that it
            is an independent contractor with no authority to contract for
            SABRE or in any way to bind or to commit SABRE to any agreement of
            any kind or to assume any liabilities of any nature in the name of
            or on behalf of SABRE.  Under no circumstances shall COMDISCO, or
            any of its employees, hold itself out as or be considered an agent
            or an employee of SABRE, and SABRE shall have no duty to provide or
            maintain any insurance or other employee benefits on behalf of
            COMDISCO or its employees.

     19.12  CAPTIONS.  The captions appearing in this Agreement have been
            inserted as a matter of convenience and in no way define, limit or
            enlarge the scope of this Agreement or any of the Sections thereto.

     19.13  SEVERABILITY.  In the event that any one or more of the provisions
            of this Agreement or the Operative Agreements is determined by a
            court of competent jurisdiction to be invalid, unenforceable or
            illegal, such invalidity, unenforceability or illegality shall not
            affect any other provisions of this Agreement or Operative
            Agreements, and this Agreement or Operative Agreements shall be
            construed as if the challenged provision had never been contained
            herein.  The parties further agree that in the event such provision
            is an essential part of this Agreement or the Operative Agreements,
            they will immediately begin negotiations for a suitable replacement
            provision.  In the event the parties cannot agree on a suitable
            replacement term, then the parties will proceed through Level Three
            (excluding Court) of the Dispute Resolution Process as outlined in
            this Agreement and make a good faith effort to settle the dispute
            in that manner.

     19.14  ENTIRE AGREEMENT.  This Agreement and the Operative Agreements
            constitute the entire agreement between the parties and supersede
            any and all previous representations, understandings, discussions
            or agreements between SABRE and Comdisco with respect to the
            subject matter of this Agreement and the Operative Agreements, and
            may only be amended by an instrument in writing signed by SABRE and
            Comdisco.  Each of Comdisco and SABRE acknowledges that it has had
            the opportunity to review this Agreement and the Operative
            Agreements with its legal counsel.

     19.15  SURVIVAL.  In the event of termination or expiration of this
            Agreement or such Operative Agreements, then those provisions,
            including but not limited to payment obligations, which by their
            nature should survive shall survive such termination or expiration.

     For example:
     [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED]

     D.   RECONCILIATION ACCOUNT

     At SABRE's option, changes in the Monthly Rental pursuant to Section B
     hereof and the Program Lease Agreement may be accumulated into a
     reconciliation account as more fully described in the Program Lease
     Agreement ("Reconciliation Account"), and the Monthly Rental may be
     adjusted ("Adjusted Rental") to reflect such changes on a semi-annual basis
     on July 1st and January 1st (the "Settlement Date").

     Adjusted Rental carried forward by SABRE to the next Settlement Date (both
     negative and positive) shall bear interest equal to the [TEXT OMITTED - 
     CONFIDENTIAL TREATMENT REQUESTED].  If during a reconciliation period 
     there is a change of [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED],
     then either SABRE or Comdisco may call an early Settlement Date.

     Additional Settlement Dates can be called by either party as provided for
     in the Program Lease Agreement and at SABRE's option, SABRE may cease to
     use the Reconciliation Account in which event changes in the Monthly Rental
     shall be as provided in Section B above. 
     
     E.   CURRENT SABRE LEASE COMMITMENTS

     SABRE has various lease commitments with regard to SABRE Equipment which
     shall be placed under this Equipment Schedule.  Comdisco and SABRE agree to
     address those leases as follows:  
     
     i)   Leases with Comdisco:  Effective as of December 31, 1998 ("Termination
          Date"), and so long as SABRE has paid all amounts then due and owing
          under the Equipment Schedules described below, Comdisco's and SABRE's
          obligations with respect to the Equipment Schedules described below
          shall terminate, except such obligations in connection therewith which
          expressly survive said termination.  Effective as of January 1, [TEXT

          the Equipment Schedules described below (which Equipment is included

     ii)  Leases with parties other than Comdisco ("Third Party Lease(s)"):
          Effective January 1, 1999 and for so long as this Equipment Schedule
          remains in effect, Comdisco shall pay, on

          SABRE's behalf, to the lessor specified on Attachment B the rental 
          obligations of SABRE under the Third Party Leases specified on 
          Attachment B as required by such Third Party Lease. The equipment 
          under the Third Party Leases is included in the SABRE Equipment 
          listed on the Equipment Schedule attached this Schedule as 
          Attachment C.  All Third Party Lease Equipment still in use by SABRE 
          and under this Program shall be removed from the Program effective 
          with the end of the Third Party Lease term per the Rent Adjustment 
          and Refresh Pool Mechanics described in Sections B and C of this 
          Equipment Schedule and the terms of the Program Lease Agreement.  
          Comdisco shall not be responsible to pay any rental obligations 
          extending beyond the term of the applicable Third Party Lease as 
          identified on Attachment B.
     
          If SABRE has an option to purchase the Equipment under a Third Party
          Lease at the expiration of the term of such Third Party Lease, SABRE
          shall notify Comdisco of such option.  In such event, SABRE shall have
          the option of purchasing the Equipment for its own account.  If SABRE
          elects not to purchase the Equipment for its own account, then upon
          Comdisco's request, SABRE shall exercise the purchase option and
          subsequently sell the Equipment to Comdisco for the option purchase
          price, plus all actual and reasonable costs incurred by SABRE
          associated with such purchase.  Notwithstanding the above, SABRE may
          at its option, at the end of the term of such Third Party Lease, renew
          such Third Party Lease with the Third Party Lessor and continue to
          operate the equipment outside of the Program.
     
     In the event of a default by SABRE under this Equipment Schedule, and upon
     at least 30 days notice, Comdisco's obligation to make payments as
     described in this Section E shall cease until SABRE's default has been
     cured.  In addition, Comdisco's obligation to make payments as described
     herein shall cease if the Equipment Schedule is terminated pursuant to the
     terms of the Program Lease Agreement.  SABRE acknowledges that except as
     specifically provided for herein, it retains the obligation to make all
     rental payments to such entities.  Comdisco's notice made pursuant to this
     paragraph of Section E shall state the last payment to be made by Comdisco
     under the Third Party Lease absent a cure by SABRE.

     F.   INDIAN TERRITORY CREDIT 

     SABRE and Comdisco agree that the Equipment under lease may qualify for
     incremental accelerated tax benefits under the federal tax law in light of
     IRS Notice 98-45, issued in August, 1998, and Internal Revenue Code Section
     168(j)(6). SABRE and Comdisco further agree that the incremental
     accelerated tax benefits relate specifically to the fact that tangible
     personal property that is located on Indian Reservation land within the
     meaning of IRC Section 168(j)(6) (including Former Indian Reservations in
     Oklahoma as clarified by Notice 98-45) receives three year tax depreciation
     and not five year tax depreciation under the federal income tax laws. 

     The Equipment that qualifies for this treatment as of September 30, or
     March 31 for Equipment that has been installed for more than 3 years, of
     each year shall be deemed "Indian Territory Equipment" for that year. 
     Comdisco shall pay SABRE a credit ("Indian Territory Credit") in the

     form of cash to SABRE on or before November 15th of each year starting in 
     1998 for Indian Territory Equipment for that year.

     The Indian Territory Credit for any given year shall be equal to the sum of
     the credits for all Indian Territory Equipment for that year calculated as
     a percentage of the Equipment Cost for each item of Indian Territory
     Equipment based on the following table:

     For Equipment to qualify as Indian Territory Equipment, the following
     conditions must all apply: (a) the incremental accelerated tax benefits as
     described above must not have been repealed; (b) the Equipment continues to
     be located on an Indian Reservation as defined by IRC Section 168(j)(6) (or
     Former Indian Reservations in Oklahoma as defined in Notice 98-45) for the
     period of time set forth in the chart above to calculate the credit; (c)
     the Equipment continues to be leased under this Equipment Schedule as of
     September 30 or March 31 the relevant year as described; and (d) the
     Equipment is included in this Equipment Schedule and entered into on the
     basis that Comdisco intends to claim, as allowed by the Internal Revenue
     Code, such deductions for tax depreciation, interest on purchase money and
     other tax benefits as are provided to an owner of Equipment.
     
     
     PROGRAM LEASE AGREEMENT:  This Equipment Schedule is issued pursuant to the
     Program Lease Agreement between the parties hereto identified on page 1 of
     this Equipment Schedule.  All of the terms and conditions of the Program
     Lease Agreement are incorporated herein by this reference and made a part
     hereof as if such terms and conditions were set forth in this Equipment
     Schedule and this Equipment Schedule constitutes a separate lease for the
     Equipment.  In the event of a conflict between the terms and conditions of
     this Equipment Schedule, and the Program Lease Agreement, the order of
     precedence is set forth in Section 19.17 of the Program Lease Agreement. 
     The parties hereby reaffirm all of the terms and conditions of the Program
     Lease Agreement (including, without limitation, the representations and
     warranties set forth in Section 44.3, 5.7 and 7 of the Program Lease
     Agreement).  This Equipment Schedule may not be amended or rescinded except
     by a writing signed by both parties.

                                 SERVICES SCHEDULE 
                                      FOR THE
                              PROGRAM LEASE AGREEMENT
                                      BETWEEN
                                 COMDISCO AND SABRE

During the Term of the Program Lease Agreement ("Agreement") or any extension
thereof, Comdisco agrees to provide to SABRE in connection with Equipment and
Managed Equipment the Services as listed hereunder which will be further defined
or modified during completion of the Life-Cycle Process Analysis and
Optimization and optional Implementation tasks (as provided for under a separate
agreement).  Any changes to the Services will be documented as an amendment to
the Agreement and this Services Schedule.  Subject to the terms and conditions
of the Agreement, Comdisco agrees to provide the following Services:

In the event SABRE requests Comdisco to perform services other than those
described in this Services Schedule, the scope and price for such services must
be mutually agreed to between the parties, and Comdisco will have no obligation
to perform such services unless both parties have executed the Comdisco Change
Control Form.  Charges for such services shall be as agreed to between the
parties.  SABRE shall pay within 30 days after receipt of an invoice for such
services all items on a related invoice that are not the subject of a bona fide
dispute.

Comdisco's ability to deliver the Services under this Services Schedule for
Equipment and Managed Equipment are contingent upon SABRE's accurate entry of
asset data during receipt and installation of an asset and SABRE's accurate
entry of data relating to changes (moves, adds, changes, removal and break/fix
events that affect the configuration or its components that are being tracked)
to an asset.

     C.  SERVICE LEVEL AGREEMENTS


                                   CONFIDENTIAL
                     THE SABRE GROUP, INC. AND COMDISCO, INC.         03/16/99
                                       PAGE 4
<PAGE>

          Comdisco and SABRE will jointly develop and agree to service level
          agreements (hereinafter "Service Level Agreement(s)" or "SLA(s)")
          between SABRE and Comdisco that will be used to measure the
          performance of activities supported by the Service Desk.  In addition,
          Comdisco and SABRE will jointly develop the data input and reporting
          requirements of the Service Desk.  In the event the parties cannot
          agree on all or a portion of the Comdisco/SABRE Service Level
          Agreement within ninety (90) days of the date said SLA's are tendered
          to SABRE for approval, then the parties will proceed through Level
          Three (excluding Courts) of the Dispute Resolution Process as outlined
          in the Agreement and make a good faith effort to settle the dispute in
          that manner.  In the event the parties are unable to reach agreement 
          through the Dispute Resolution Process, then either party may
          terminate this Services Schedule and SABRE's sole remedy shall be a
          reduction in the Monthly Rental under the Agreement of $[TEXT OMITTED
          - CONFIDENTIAL TREATMENT REQUESTED] per month.  Comdisco's sole remedy
          is that Comdisco will be relieved of its obligation to perform the 
          Services hereunder.  The Comdisco/SABRE SLA's for which the parties
          can exercise the above termination rights, are limited to those 
          Services provided by the Comdisco Service Desk which are as follows:
          Order Entry, Lease Management, and Database Monitoring for 
          Procurement, Change, and Disposal Management for Mainframes as 
          defined herein.
     
          To support the development of the Service Level Agreements, Comdisco
          and SABRE will perform the following project activities:   

          -    Define, with SABRE assistance, the requirements for SLAs with
               each of the following:
               -    Between Comdisco and SABRE with regard to the Service Desk.
               -    Between SABRE and internal groups
               -    Between SABRE and vendors of SABRE
          -    Finalize the number and types of SLAs required
               -    Primary.
               -    Secondary.
          -    Establish procedures and metrics for developing SLAs
          -    Establish internal approval process
          -    Develop SLAs
          -    Develop SLA reporting criteria
          -    Meet with parties affected by SLAs
          -    Assist in negotiations with affected parties
          -    Assist with the update and approval for negotiated SLAs
          -    Gain Approval
          -    Institute SLAs

2.   FEES AND SCOPE

     The fees and scope for Service Desk staffing are calculated on an estimated
     base of up to [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] assets.  
     For the purposes of the Service Desk, and not for any other purpose, the 
     "[TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] assets" are Mainframe 
     and Mid-Range assets and are defined as a single piece of equipment, or 
     equipment

                                   CONFIDENTIAL
                     THE SABRE GROUP, INC. AND COMDISCO, INC.         03/16/99
                                       PAGE 5
<PAGE>

     physically connected in such a way to function as a single unit, which will
     be identified with a SABRE bar-code number affixed to the outside
     structure.  The asset may or may not contain additional components that may
     also be inventoried, but will not be included in the count.  Any assets in
     excess of the [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] assets may 
     require additional staffing and additional costs to SABRE.  Subject to the
     foregoing and the following paragraph, in order to effectively 
     accommodate growth, which could impact the asset base and therefore 
     staffing requirements, appointed Comdisco's and SABRE's representatives 
     will formally meet once a quarter, or more often if jointly agreed upon, 
     to assess the impact of changes to the asset base and come to a mutually 
     agreeable resolution.

     If at any time after the first year of the Services Schedule the activity
     level is such that the parties, in good faith, determine that the
     Asset/Lease Manager function should be performed by SABRE then in such
     event, the Services portion of the Monthly Rental will be reduced by
     $[TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] per month as of the 
     effective date of such termination and the service levels under the SLAs 
     will be adjusted accordingly.  In addition, the parties have anticipated 
     that the staffing levels specified for the Service Desk will handle up to
     the [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED] assets.  If at any 
     time during the Term of this Services Schedule, SABRE's activity level 
     requires additional staffing to enable Comdisco to perform the Services 
     in accordance with this Services Schedule, the parties will in good 
     faith adjust the staffing levels and the cost to SABRE.

     As long as all amounts then due and owing (other than a Disputed Amount)
     are paid by SABRE and SABRE gives Comdisco at least ninety (90) days prior
     notice, SABRE may terminate the Services effective on December 31, [TEXT 
     OMITTED - CONFIDENTIAL TREATMENT REQUESTED], or upon the expiration of any
     calendar year thereafter as specified in the termination notice.  The 
     Monthly Rental shall be reduced by $[TEXT OMITTED - CONFIDENTIAL TREATMENT
     REQUESTED] per month as of the effective date of such termination, which 
     the parties agree represent the monthly fee for the Services.  

     Upon prior approval by SABRE and not more than quarterly, reasonable
     expenses for travel and living incurred in association with the performance
     of Comdisco's ongoing quality control during the delivery of the Services,
     or as a result of a SABRE request, will be billed separately at Comdisco's
     cost.  SABRE shall reimburse Comdisco for such expenses upon submission by
     Comdisco of an expense statement in a form authorized by SABRE. 

     Any Services performed by Comdisco hereunder shall be performed by
     qualified and fully trained personnel.  Additionally, the Services shall be
     performed in a commercially reasonable and professional manner.  All
     Service personnel assigned for particular functions under this Services
     Schedule have the skills, certifications and qualifications indicated
     herein.
      
3.   YEAR 2000 WARRANTY

     SABRE and Comdisco agree as follows:

     The following are definitions for the purposes of this year 2000 Service
     warranty:


                                   CONFIDENTIAL
                     THE SABRE GROUP, INC. AND COMDISCO, INC.         03/16/99
                                       PAGE 6
<PAGE>

     "Services Related Products" means (i) any products that Comdisco provides
     to use as tools to perform Services under this Services Schedule, (ii) any
     SABRE owned or licensed products which Comdisco provides Services for under
     this Services Schedule which were demonstrated to Comdisco's satisfaction
     to be Year 2000 Compliant prior to the Comdisco performing the Services and
     such Services were the direct cause of any Year 2000 non-compliance, and
     (iii) any deliverables provided to SABRE by Comdisco as part of its
     Services.

     "Year 2000 Compliant" means that the software, micro-code, and hard wired
     features of the Services Related Products that have date data fields,
     processing logic, outputs, and interfaces will correctly recognize,
     process, and otherwise support the Gregorian calendar year 2000 and beyond.
     The Services Related Products, as well as all features, updates, upgrades,
     and options shall so operate regardless of whether SABRE uses them prior
     to, during or after the calendar year 2000, so long as the hardware and
     software interfacing with the Services Related Products can correctly
     recognize, process, and otherwise support the calendar year and beyond.

     Notwithstanding anything to the contrary in this Services Schedule, except
     for SABRE owned and licensed products under (ii) above, Comdisco warrants
     that the Services Related Products are Year 2000 Compliant. Comdisco shall
     not be responsible for maintaining the Year 2000 Compliant status of the
     Services Related Products on and after the date of any changes to them made
     by any person other than Comdisco under this Services Schedule, which
     resulted in the Services Related Products being rendered non-Year 2000
     Compliant.  Comdisco will informally over time provide to SABRE compliance
     status information for Comdisco's legacy systems and then current Services
     offerings and tools, and will communicate to SABRE possible work around
     options for non-compliant functionality.  This warranty shall survive the
     expiration or termination of this Services Schedule for a period of 12
     months from January 1, 2000.

4.  CHANGE CONTROL   

     Upon the identification of any change to the Services, SABRE and Comdisco
     will complete a Comdisco Change Control Form ("CCF").  The Comdisco Change
     Control process is described below:
     
     Any changes to the Services must be mutually agreed upon by both Comdisco
     and SABRE to ensure common expectations are maintained for the
     deliverables. Mutually acceptable changes will become the basis of a
     modification to this Services Schedule with a Statement of Change ("SOC"). 
     Neither party shall have any obligation to commence work in connection with
     a change request prior to completing this Change Control Process.

     A change to the scope of the Services must be submitted in writing, using
     Comdisco's standard CCF and this process:

     -    The requested change will be described by the party originating the
          change (either SABRE or Comdisco) using the CCF.  The CCF will then be
          submitted to SABRE for approval.


                                   CONFIDENTIAL
                     THE SABRE GROUP, INC. AND COMDISCO, INC.         03/16/99
                                       PAGE 7
<PAGE>

     -    SABRE will evaluate the CCF and either reject it, or sign and send the
          form to Comdisco.
     -    Comdisco will work with SABRE as required to identify and document the
          scope of change using an SOC.
     -    Comdisco will approve and sign the SOC.
     -    The SOC will be delivered to SABRE for approval and final signature.
     -    Upon receipt of an SOC signed by both companies, Comdisco will
          implement the changes and document closure on the CCF.  If SABRE
          decides not to sign the SOC, the reasons will be documented on the CCF
          as part of closing this requested change.

5.   SUBCONTRACTORS  

     In the event of any replacement of the Service Desk staff, Comdisco may
     upon prior notice to SABRE utilize a subcontractor on a temporary basis to
     maintain the appropriate service levels as provided for under this Services
     Schedule.  Notwithstanding the above, Comdisco shall remain liable for such
     Service.

6.  ELIGIBILITY TO WORK  

     Comdisco warrants that each Comdisco employee furnished by Comdisco is
     eligible to legally work in the United States (being a citizen, documented
     resident alien or possessing other eligibility documentation), and that
     said Comdisco employee is free from any legal or contractual restraints
     prohibiting working or the exercise of skills, including employment
     agreements or non-competitive agreements with other or former employers
     (excluding any agreement between Comdisco and Comdisco employee.

                                 COMDISCO STAFFING

1.   ADEQUATE PERSONNEL   

     Comdisco shall ensure that an adequate number of appropriately qualified
     and trained personnel are employed and available at all times to provide
     and support the Service Desk in accordance with the terms of this Services
     Schedule.  Comdisco shall augment through the Change Control Process the
     personnel assigned to SABRE from time to time as may be necessary to carry
     out special projects requested by SABRE.  If Comdisco personnel are
     reassigned during the Term, Comdisco shall use its best efforts to ensure a
     smooth transition, including cooperation between the replaced and newly
     assigned personnel or, where appropriate, an overlap in the assignment of
     such personnel to SABRE.

     Comdisco shall provide the following number of personnel to support SABRE
     during the Term of this Services Schedule and any extension, unless the
     parties agree (which agreement will not be unreasonably withheld) that such
     number should be adjusted.  The parties agree to meet annually to review
     the staffing levels required for Comdisco to perform the Services to be
     provided herein.

*    The Service Manager reviews with SABRE's Project Manager the project 
     status and deliverables monthly over the life of the project.
**   The Asset/Lease Manager is a full time operational position who transitions

2.   COMDISCO SERVICE MANAGER   

     No later than forty-five (45) days from the execution of this Services
     Schedule by both parties, Comdisco shall appoint a Service Manager with
     sufficient experience and expertise to act as the primary liaison between
     the parties and to assume overall responsibility for the party's
     performance under this Services Schedule.  If Comdisco reassigns its
     Service Manager or such individual has any other conflict which would
     impact the delivery of the Services, Comdisco will promptly replace such
     person with another person no less qualified or knowledgeable as to
     Comdisco's business.  Comdisco will also make available to SABRE other
     reasonably necessary resources on a timely basis.  Comdisco will ensure

     business, including technical, financial and functional requirements
     relevant to the Services.

3.   REASSIGNMENT OF PERSONNEL 

     Absent SABRE's consent (which shall not be unreasonably withheld) or as
     otherwise provided herein, for 12 months from the Effective Date of this
     Services Schedule, Comdisco shall not eliminate any personnel positions
     that have been provided as of the Effective Date.  Except in situations
     where personnel leave the employ of Comdisco, Comdisco shall avoid
     unreasonable churn in the assignment and reassignment of Comdisco
     personnel.  

4.   REMOVAL OF PERSONNEL 

     SABRE may notify Comdisco when it finds any Comdisco personnel unacceptable
     to SABRE for any lawful reason, including SABRE's reasonable determination
     that he or she is not qualified to perform the work to which he or she is
     assigned.  Upon receipt of such notice Comdisco shall within 10 business
     days review the matter with SABRE.  Notwithstanding the above, such notice
     of unsatisfactory performance shall in no way limit or restrict SABRE
     rights under this Services Schedule or relieve Comdisco of its obligations
     to perform.

5.   REPORTS   

     During the Term of this Services Schedule, Comdisco shall provide SABRE no
     later than the 16th day of the following month with (i) monthly statements
     reflecting the activity of the Refresh Equipment and Growth Equipment
     supplied to SABRE during the prior month in the detail as agreed upon

     reports to identify the Equipment being returned or refreshed under the
     Program.  SABRE shall provide Comdisco with not less than 30 days written
     notice of its intent to return or refresh Equipment; provided, however,
     nothing herein shall be deemed to limit SABRE's rights under Part V,
     Section 4 of this Services Schedule if SABRE requires a shorter time frame.

                                    OF COMDISCO

1.  ACCESS AND SECURITY  

     Subject to the subsections below, Comdisco personnel shall have such access
     at all times to SABRE's premises as is reasonably necessary to provide the
     Service in accordance with the terms of this Services Schedule.

     All Comdisco personnel shall comply with SABRE's or SABRE's customers
     security requirements where such security requirements are posted or SABRE
     or SABRE's customer otherwise advises Comdisco personnel of such
     requirements.  When deemed appropriate by SABRE or SABRE's customer,
     Comdisco personnel will be issued passes or visitor identification cards
     which must be presented upon request to SABRE's or SABRE's customer
     personnel and surrendered promptly upon SABRE's or SABRE's customer demand
     or upon termination of this Services Schedule.  SABRE or SABRE's customer
     shall have the right to refuse to issue such passes or identification cards
     or immediately to terminate the right of access should SABRE or SABRE's
     customer determine in its sole discretion for any lawful reason that such
     termination is in SABRE's or SABRE's customer best interest.  SABRE shall
     promptly notify Comdisco of any such refusal or termination of access, and
     Comdisco shall have the opportunity to demonstrate to SABRE that refused or
     terminated rights of access should be granted or reinstated.  In no event
     shall the termination of such right of access or refusal to issue such
     passes or identification cards to a Comdisco personnel excuse Comdisco from
     performance herein, provided Comdisco has 3 business days from receipt of
     such notice to replace the Comdisco personnel.
     
     IN WITNESS WHEREOF, the parties have caused this Services Schedule to be
     executed by their duly authorized officers as of the day and year first set
     forth above.
