                obligations under the prepayment transaction (the
                "Obligations"), solely to the extent that information relating
                to such nature, priority and amount has not been received,
                reviewed and approved by Amex acting reasonably and in good
                faith on or before the date of the Commitment Letter, and that
                the aggregate liens against the collateral shall secure only the
                Obligations, the Third Party Loan Facility (which liens shall be

                more specifically set forth herein), and other third party

                business or financial condition of the Delta Companies taken as
                a whole from that shown in Delta's last filed 10-K, as updated
                by Delta's subsequent public filings delivered by a Delta
                Company to Amex prior to the date of the




                Commitment Letter, (ii) no litigation commenced which would
                reasonably be expected to have a material adverse impact on the
                ability of the Delta Companies to repay the advance payments or
                which challenges the legality or enforceability of the
                prepayment transactions, and (iii) absence of material
                inaccuracy in material information (other than projections,
                which shall have been prepared in good faith based upon
                assumptions that are believed by the Delta Companies to be
                reasonable at the time made) taken as a whole furnished by Delta
                and/or Delta subsidiaries to Amex in connection with the
                prepayment transaction and not corrected prior to the making of
                the Initial Installment by subsequent information provided to
                Amex; provided that a "material adverse change" shall not be
                deemed to have occurred solely by virtue of (x) the fact that
                one or more Delta Companies is a debtor under the Bankruptcy
                Code so long as the Delta Companies have complied with the
                provisions described in "Treatment of the prepayment transaction
                in Bankruptcy" below, or (y) the occurrence of any event, change
                or condition that has been reflected in the then current
                business plan that is acceptable to Amex.

                in the business plan of Delta or the Delta Companies after the
                date of the Commitment Letter that differs (in Amex's reasonable
                judgment) materially and adversely from the current business
                plan of Delta and the Delta Companies, Delta shall deliver
                information reasonably requested by Amex with respect to such
                change (including, without limitation, information with respect
                to the effect of such change on the Delta Companies' debt
                restructuring program) and Amex shall be reasonably satisfied
                therewith.

                and all documents and instruments ancillary thereto (including
                such other agreements, collateral instruments and documents,
                opinions, and certifications), and delivery of such information
                in each case, as Amex may require in its reasonable judgment
                with respect to the prepayment transaction and the Amex/Delta
                Agreements and the Card Service Agreement.

CONDITIONS TO FINAL INSTALLMENT: The obligation of Amex to pay the final
prepayment installment (the "Final Installment") shall be subject to the
satisfaction as of the date of the Final Installment of the conditions in
clauses (i), (iii) and (vii) above to payment of the Initial Installment and the
satisfaction of the following additional conditions:

        (i)     no material default to be mutually agreed to by the parties to

                Companies that are captive insurance companies, Guardant and
                non-United States subsidiaries) are subject to a proceeding
                under the Bankruptcy Code and complied with the provisions

                correct as of such date).

        (iii)   there shall have been (i) no material adverse change in the
                business or financial condition of the Delta Companies taken as
                a whole from the date of the Initial Installment, (ii) no
                litigation commenced which would reasonably be expected to have
                a material adverse impact on the ability of the Delta Companies
                to repay the advance payments or which challenges the legality
                or enforceability of the prepayment transactions, and (iii)
                absence of material inaccuracy in material information (other
                than projections, which shall have been prepared in good faith
                based upon assumptions that are believed by the Delta Companies
                to be reasonable at the time made) taken as a whole, furnished

                transaction in Bankruptcy" below, or (y) the occurrence of any
                event, change or condition that has been reflected in the then
                current business plan that is acceptable to Amex.

                month immediately preceding the proposed payment date for the
                Final Installment with the financial covenants.

                        CORPORATION, ET AL., DEBTORS, U.S. Bankruptcy Court for
                        the Northern District of Illinois, case no. 02-B-48191.

                (e)     all "first-day" and related orders entered by the
                        Bankruptcy Court shall be in form and substance
                        reasonably acceptable to Amex;

        (ii)    clauses (ii) and (vii) of "Conditions to Initial Installment" as
                set forth above shall be without force or effect, and clause
                (ii) of the "Conditions to Final Installment" as set forth above
                shall be without force or effect to the extent that the
                Bankruptcy Cases or the conditions that led to the Bankruptcy
                Court proceedings of the applicable Delta Companies cause the
                conditions in such clauses not to be satisfied. The existence of
                bankruptcy litigation, the failure to make payments or otherwise
                perform under agreements with third parties (i.e., persons other
                than Amex and its affiliates) based upon the existence of the
                automatic stay resulting from the Bankruptcy Case will not
                affect the conditions set forth in "Conditions to Initial
                Installment" and "Conditions to Final Installment" above so long
                as the existence of such litigation and such failures to pay
                and/or perform do not adversely affect Amex;

        (iii)   the following shall be additional events of default: (a) the
                conversion or dismissal of the Bankruptcy Cases, (b) the
                appointment of a Chapter 11 trustee or examiner with expanded
                powers and/or powers of a Chapter 11 trustee in the Bankruptcy
                Cases, (c) confirmation of plan of reorganization which is not
                acceptable to Amex with respect to the treatment of Amex's
                claims and liens, and is not otherwise reasonably acceptable to
                Amex, and (d) the Approval Order or any other Bankruptcy Court
                order authorizing the assumption of the Amex/Delta Agreements
                and/or the TRS Agreements is reversed, vacated or stayed or, in
                a manner material and adverse to Amex, amended, supplemented or
                otherwise modified; and

        (iv)    subject to the satisfaction of the conditions set forth in
                clauses (i), (ii) and (iii) above, the commencement of the
                Bankruptcy Cases shall not be an event of default, nor shall any
                Delta Company's rejection of or resulting or deemed default
                under an executory contract or lease, or its attempted
                recharacterization of a lease as a financing transaction, or
                contested matters, adversary proceedings or similar litigation
                to which Amex is a party in interest, so long as such actions do
                not adversely affect Amex.

(B)     In the event that the Delta Companies shall become the subject of
        Bankruptcy Cases on or after the date on which Amex has made all advance
        payments to Seller required pursuant to the prepayment transaction,
        then:

        (i)     the Delta Companies shall obtain interim (the "Interim Adequate
                Protection Order") and/or final (the "Final Adequate Protection
                Order", and collectively, the "Adequate Protection Order")
                orders from the Bankruptcy Court providing adequate protection
                of Amex' interests in the collateral and otherwise protecting
                Amex' rights with respect to the Delta Companies, which orders,
                as presented to the Bankruptcy Court for approval, shall be in
                such form and substance as shall have been agreed upon by Amex
                and Seller as of the commencement of the Bankruptcy Cases and

                        assumed pursuant to order of the Bankruptcy Court) of
                        the TRS Agreements (the Card Service Agreement being
                        assumed as amended by the "Chapter 11 Addendum" thereto
                        in such form and substance as shall have been agreed
                        upon by Amex and Seller as of the initial closing of the
                        prepayment transaction) and the Amex/Delta Agreements;

                (b)     grant, as adequate protection of Amex' interests in the
                        collateral, super-priority administrative expense
                        status, as set forth in clause "(A)(i)(a)(III)" above;


                                       5


                (c)     grant, as adequate protection of Amex' interests in the
                        collateral, replacement and additional liens, offset
                        rights, recoupment rights and/or security interests in
                        and with respect to the collateral, subject to the
                        Carve-Out and having priorities consistent with these
                        provisions and any Intercreditor Agreements, as security
                        for such adequate protection claim;

                (d)     provide that any interests in the collateral granted by
                        the Bankruptcy Court pursuant to any adequate protection
                        orders entered with respect to the Third Party
                        Pre-Petition Facility or pursuant to any Third Party DIP
                        Facility shall not encumber the collateral in any manner
                        inconsistent with these provisions and any Intercreditor
                        Agreements;

                (e)     provide that other than with respect to the Third Party
                        DIP Facility, the Bankruptcy Court shall not encumber
                        the collateral with any lien or security interest which
                        is equal or senior in priority to the liens and security

                        agents and lenders under such adequate protection orders
                        as are entered with respect to the Third Party

                        approving and authorizing same, including without
                        limitation the cross-default, intercreditor and/or
                        subordination provisions thereof, shall be consistent
                        with these provisions and any Intercreditor Agreements,
