        (iii)   EVENTS OF DEFAULT. Paragraph 7 shall be deleted and replaced in
        its entirety by the following paragraph:

                "For the purposes of Section 5(a)(iii) of this Agreement, an
                Event of Default will exist with respect to a party if that
                party fails (or fails to cause its Custodian) to make, when due,
                any Transfer of Eligible Credit Support, Posted Credit Support
                or the Interest Amount, as applicable, required to be made by it
                and that failure continues for two Local Business Day after the
                notice of that failure is given to that party; provided, that,
                with respect to a failure to Transfer Eligible Credit Support,
                at least (x) 30 Local Business Days have elapsed after a Ratings
                Event with respect to Party A and the guarantor under each
                Qualified Guaranty (if any) has occurred, or (y) 10 Business
                Days have elapsed after an S&P Ratings Event , and such failure
                is not remedied on or before the third Local Business Day after
                notice of such failure is given to Party A".

        (iv)    NO COUNTERCLAIM. A party's rights to demand and receive the
        Transfer of Eligible Collateral as provided hereunder and its rights as
        Secured Party against the Posted Collateral or otherwise shall be
        absolute and subject to no counterclaim, set-off, deduction or defense
        in favor of the Pledgor except as contemplated in Sections 2 and 6 of
        the Agreement and Paragraph 8 of this Annex.

        (v)     HOLDING COLLATERAL. The Secured Party shall cause any Custodian
        appointed hereunder to open and maintain a segregated account (the "SWAP
        COLLATERAL ACCOUNT") and to hold, record and identify all the Posted
        Collateral therein and, subject to Paragraphs 6(c) and 8(a), such Posted
        Collateral shall at all times be and remain the property of the Pledgor
        and shall at no time constitute the property of, or be commingled with
        the property of, the Secured Party or the Custodian.

        (vi)    INVESTMENT OF CASH POSTED COLLATERAL. Cash Posted Collateral
        shall be invested in Permitted Investments as directed by Party A, with
        gains and losses incurred in respect of such investments to be for the
        account of Party A, subject to the following parameters: the Cash Posted
        Collateral shall be invested in such overnight (or redeemable within two
        Local Business Days of demand) investments rated at least (x) AAAm or
        AAAm-G by S&P and (y) Prime -1 or Aaa by Moody's as directed by Party A
        (provided, that such investment shall be held uninvested or invested at
        the direction of Party B if an Event of Default or an Additional
        Termination Event has occurred with respect to which Party A is the
        defaulting or sole Affected Party and Party B has designated an Early
        Termination Date with respect thereto). Such instructions may be
        delivered as standing instructions.

        (vii)   RETURN OF POSTED COLLATERAL. At any time Party A is required to
        post collateral pursuant to Part 5(i)(ii) of the Schedule, Party A shall
        be obligated to transfer Eligible Collateral in accordance with the
        terms of this Annex. If Party A is so required to post collateral in
        relation to a Collateralization Event or a Ratings Event and thereafter
        ceases to be required to post collateral under Part 5(i)(ii) of the
        Schedule (and provided that no Event of Default exists with respect to
        Party A) or Party A has made a Permitted Transfer under this Agreement,
        then Party A's obligations to transfer Eligible Collateral under this
        Annex will immediately cease with respect to that Collateralization
        Event or Ratings Event, and Party B will, upon demand by Party A, return
        to Party A, or cause its Custodian to return, all Posted Collateral held
        under this Annex. The Secured Party is authorized to liquidate any
        Posted Collateral pursuant to written instructions from Party A.


                                        6



        (viii)  EXTERNAL VERIFICATION OF MARK-TO-MARKET VALUATIONS. If the
        long-term senior unsecured debt of Party A is rated BBB or below by S&P,
        once every month, Party A will at its own expense verify its
        determination of Exposure of the Transaction on the next Valuation Date
        by seeking quotations from two (2) Reference Market-makers (provided,
        that a Reference Market-maker may not be used more than four times
        within each 12 month period) for their determination of Exposure of the
        Transaction on such Valuation Date and the Valuation Agent will use the
        greater of either (a) its own determination or (b) the high quotation
        for a Reference Market-maker, if applicable for the next Valuation Date
        and cure any deficiency in collateral value within three Local Business
        Days. Party A shall provide the quotations of such Reference
        Market-makers to S&P.

        (ix)    EXPENSES. Notwithstanding Paragraph 10, the Pledgor will be
        responsible for, and will reimburse the Secured Party for, all transfer
        and other taxes and other costs involved in the transfer of Eligible
        Collateral.

        (x)     LIMIT ON SECURED PARTY'S LIABILITY. The Secured Party will not
        be liable for any losses or damages that the Pledgor may suffer as a
        result of any failure by the Secured Party to perform, or any delay by
        it in performing, any of its obligations under this Annex if the failure
        or delay results from circumstances beyond the reasonable control of the
        Secured Party or its Custodian, such as interruption or loss of computer
        or communication services, labor disturbance, natural disaster or local
        or national emergency.
