Item 1.01. Entry into a Material Definitive Agreement.

     (a) Credit Agreement. The information set forth under Item 2.03 of this Current Report on Form 8-K is hereby incorporated in this Item 1.01(a) by reference.

     (b) Harwood Street Funding. Centex Corporation (“Centex”) conducts mortgage lending operations through its subsidiary, CTX Mortgage Company, LLC (“CTX Mortgage”). CTX Mortgage funds the origination of mortgage loans primarily through the sale of certain of the loans to Harwood Street Funding I, LLC (“HSF-I”). HSF-I is a special purpose entity for which Centex is the primary beneficiary and, beginning July 1, 2003, has been consolidated with Centex’s financial services segment pursuant to FASB Interpretation No. 46. Currently, the maximum amount of debt in the form of notes and certificates HSF-I is allowed to have issued and outstanding is $3.0 billion.

     HSF-I previously entered into a swap arrangement with Bank of America, N.A. (the “BA Harwood Swap”) under which the bank has agreed to make certain payments to HSF-I, and HSF-I has agreed to make certain payments to the bank, the net effect of which is that the bank has agreed to bear certain interest rate risks, non-credit related market risks and prepayment risks related to the mortgage loans held by HSF-I. The purpose of this arrangement is to provide credit enhancement to HSF-I by permitting it to hedge these risks with a counterparty having short-term credit ratings of A-1+ from Standard & Poor’s Ratings Services, a Division of The McGraw-Hill Companies, Inc. (“S&P”) and P-1 from Moody’s Investors Service, Inc. (“Moody’s”). However, Centex effectively bears all interest rate risks, non-credit related market risks and prepayment risks that are the subject of the BA Harwood Swap because Centex has entered into a separate swap arrangement (the “BA Harwood Back Swap”) with the bank pursuant to which Centex has agreed to pay to the bank all amounts that the bank is required to pay to HSF-I pursuant to the BA Harwood Swap plus a monthly fee equal to a percentage of the notional amount of the BA Harwood Swap. CTX Mortgage executes forward sales of mortgage loans to hedge the risk of reductions in value of mortgages sold to HSF-I or maintained under secured financing agreements. These sales offset the majority of Centex’s risk as the counterparty under the BA Harwood Back Swap. These arrangements are described in more detail in Centex’s Annual Report on Form 10-K for the fiscal year ended March 31, 2007 filed with the Securities and Exchange Commission.

     On July 18, 2007, HSF-I entered into (a) an amended version of the BA Harwood Swap with Bank of America, N.A. pursuant to which the notional amount of the BA Harwood Swap was reduced from $3.0 billion to $2.25 billion and (b) two new swap arrangements with JPMorgan Chase Bank, N.A. and Calyon New York Branch. Each of the two new swap arrangements is substantially similar to the BA Harwood Swap, except that the notional amount of the swap with JPMorgan Chase Bank, N.A. is $0.25 billion and the swap with Calyon New York Branch is $0.5 billion (that is, the total notional amount of interest rate swaps to which HSF-I is a party continue to be $3.0 billion). Also on July 18, 2007, in connection with this restructuring of the BA Harwood Swap, Centex restructured the BA Harwood Back Swap by entering into (a) an amended version of the BA Harwood Back Swap with Bank of America, N.A. and (b) two new back swap arrangements with JPMorgan Chase Bank, N.A. and Calyon New York Branch. All three back swaps operate in the same manner as the BA Harwood Back Swap described above.

     As part of this restructuring, on July 18, 2007, Centex entered into an International Swaps and Derivatives Association, Inc. Credit Support Annex (each, a “CSA”) with each of the three banks. If the CSAs come into effect, they would require Centex to post collateral to secure Centex’s obligations to the banks under the back swap arrangements described above. However, the CSAs will only be in effect during such time, if any, as the long-term senior unsecured debt ratings of Centex are less than “BBB-” by S&P and less than “Baa3” by Moody’s. The CSAs, when in effect, require Centex to post cash or certain other eligible collateral for the benefit of the banks during such time as the current market value (as defined in the CSAs) of the mortgage loans held by HSF-I is less than the outstanding purchase price (as defined in the CSAs) of such mortgage loans, subject to a minimum transfer amount. The amount of collateral required to be posted is equal to the difference between such current market value and outstanding purchase price, plus 1% of the difference. The outstanding purchase price of a mortgage loan is defined, generally, as the mark-to-market price (or, in the case of certain second lien loans and home equity line of credit loans, principal balance) of the loan at the time of sale of the loan to HSF-I, less principal payments made on the loan received by HSF-I.

     The foregoing summary of the CSAs is qualified in its entirety by reference to the Credit Support Annexes dated July 18, 2007 between Centex and each of the banks, copies of which are filed as exhibits to this report on Form 8-K and incorporated in this Item 1.01(b) by reference.

Item 2.03. Creation of Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

     The information set forth under this Item 2.03 relates to a credit facility that may give rise to direct financial obligations of Centex Corporation (“Centex”).

     Centex, as borrower, is a party to an unsecured, committed revolving credit facility (the “Credit Facility”) with Bank of America, N.A., as administrative agent, and certain financial institutions, as lenders. The Credit Facility provides for borrowings by Centex, and the issuance of letters of credit for the account of Centex and its subsidiaries, on a revolving basis up to an aggregate of $2,085,000,000 at any one time outstanding. This maximum facility amount may, at Centex’s request and subject to the terms and conditions of the facility, be increased up to $2,750,000,000. The stated amount of outstanding letters of credit under the Credit Facility may not exceed a total of $835,000,000, or such greater amount requested by Centex, not to exceed 50% of the maximum facility amount.

     On July 20, 2007, the Credit Facility was amended to, among other things:

(a)	delete the interest coverage ratio covenant, which means that the Credit Facility no longer contains an interest coverage ratio requirement that could create an event of default for Centex;
(b)	change the leverage ratio covenant as follows:

(i)	Centex’s leverage ratio, as of the last day of any fiscal quarter, cannot be greater than a maximum leverage ratio (initially, 60%, as adjusted from time to time thereafter, as described below);
(ii)	the maximum leverage ratio will decrease by a certain stated amount if Centex fails to maintain, for two consecutive fiscal quarters, an interest coverage ratio of at least 2.0 to 1.0 (referred to as the minimum interest coverage test);
(iii)	the maximum leverage ratio will increase by a certain stated amount if Centex satisfies, as of the last day of any fiscal quarter, the minimum interest coverage test, with the amount of the increase dependent on the extent to which the minimum interest coverage test is exceeded; and
(iv)	in no event will the maximum leverage ratio exceed 60% or be less than 40%; and

(c) change certain of the Credit Facility’s pricing provisions so that, if Centex’s interest coverage ratio is less than 2.0 to 1.0, the applicable margin for any Eurodollar borrowings by Centex (including for purpose of calculating letter of credit fees under the facility) will increase in increments ranging from 0.125% to 0.375%.

     Centex may borrow or obtain letters of credit under the Credit Facility for general corporate purposes or needs. Subject to the terms and conditions thereof, Centex may borrow or obtain letters of credit under the Credit Facility until the final maturity date, which will occur on July 1, 2010. The Credit Facility provides liquidity support for Centex’s commercial paper program, the program size of which is currently $1,250,000,000. No borrowings have been made under the Credit Facility. Centex utilizes the Credit Facility to obtain letters of credit for it and its subsidiaries.

     The foregoing summary is qualified in its entirety by reference to the Credit Agreement dated July 1, 2005, the First Amendment to Credit Agreement dated May 25, 2006, and the Second Amendment to Credit Agreement dated July 20, 2007, which govern the Credit Facility. Copies of the Credit Agreement, the First Amendment to Credit Agreement and the Second Amendment to Credit Agreement are filed as exhibits to this report on Form 8-K and incorporated in this Item 2.03 by reference. A summary of the Credit Facility in effect immediately following the First Amendment to Credit Agreement is also contained in Centex’s Current Report on Form 8-K dated June 1, 2006 filed with the Securities and Exchange Commission.

(e) Section 9.2(b)(xi) is hereby deleted in its entirety and replaced with the following:

(xi) Liens for current Taxes not yet due;

     (a) Leverage Ratio. Borrower shall not permit the Leverage Ratio (expressed as a percent), as of the last day of any fiscal quarter of Borrower, to be greater than the Maximum Leverage Ratio.

     (i) Decrease of Maximum Leverage Ratio. If at any time Borrower shall fail to maintain, for two (2) consecutive fiscal quarters, an Interest Coverage Ratio of at least the Minimum Interest Coverage Test, then the Maximum Leverage Ratio as of the last day of the second of such two consecutive fiscal quarters with respect to which Borrower shall have so failed the Minimum Interest Coverage Test (the “Coverage Test Failure Quarter”) shall be decreased as follows: (i) if the Maximum Leverage Ratio for the fiscal quarter preceding the Coverage Test Failure Quarter was 60%, then the Maximum Leverage Ratio shall be decreased by 5% to 55% as of the last day of such Coverage Test Failure Quarter; and (ii) if the Maximum Leverage Ratio for the fiscal quarter preceding the Coverage Test Failure Quarter was 55% or less, then the Maximum Leverage Ratio as of the last day of the prior fiscal quarter shall be decreased by 2.5% as of the last day of such Coverage Test Failure Quarter.

     (ii) Increase of Maximum Leverage Ratio. If at any time and from time to time in which the Maximum Leverage Ratio is less than 60% and Borrower shall satisfy the Minimum Interest Coverage Test (which for purposes of this Section 9.12(a)(ii) shall be deemed satisfied only if, on the same day on which Borrower satisfies the Minimum Interest Coverage Test, Borrower is also in compliance with the then-current Maximum Leverage Ratio), then the Maximum Leverage Ratio, effective as of the fiscal quarter immediately following the fiscal quarter with respect to which Borrower shall have so satisfied the Minimum Interest Coverage Test, shall be increased as follows:

     (A) if the Interest Coverage Ratio is equal to or greater than 2.0 to 1.0, but less than 3.0 to 1.0, on a date on which (I) the Maximum Leverage Ratio is 55%, then the Maximum Leverage Ratio for the next fiscal quarter shall be increased to 60%, and (II) the Maximum Leverage Ratio is less than 55%, then the Maximum Leverage Ratio for the next fiscal quarter shall be increased by 2.5%;

     (B) if the Interest Coverage Ratio is equal to or greater than 3.0 to 1.0, but less than 4.0 to 1.0, on a date on which (I) the Maximum Leverage Ratio is equal to or greater than 50%, then the Maximum Leverage Ratio for the next fiscal quarter shall be increased to 60%, and (II) the Maximum Leverage Ratio is less than 50%, then the Maximum Leverage Ratio for the next fiscal quarter shall be increased by 10%; and

Second Amendment to Centex Credit Agreement

4

     (C) if the Interest Coverage Ratio is equal to or greater than 4.0 to 1.0, then the Maximum Leverage Ratio for the next fiscal quarter shall be increased to 60%.

     (iii) Limitation on Increases and Deceases. Notwithstanding the foregoing, in no event shall the Maximum Leverage Ratio exceed 60% or be less than 40%.

     (iv) Effectiveness of Change in Maximum Leverage Ratio. Any decrease of the Maximum Leverage Ratio provided for in this Section 9.12(a) shall be effective as of the Coverage Test Failure Quarter as provided in Section 9.12(a)(i), and the Maximum Leverage Ratio (as so decreased) shall remain in effect thereafter unless and until adjusted as provided in Section 9.12(a)(i) or (ii). Any increase in the Maximum Leverage Ratio shall be effective as of the fiscal quarter next succeeding the fiscal quarter in which Borrower satisfies the Minimum Interest Coverage Test as provided in Section 9.12(a)(ii), and the Maximum Leverage Ratio (as so increased) shall remain in effect thereafter unless and until adjusted as provided in Section 9.12(a)(i) or (ii).

     (v) Measure of Compliance. Borrower’s satisfaction of the Minimum Interest Coverage Test shall be measured on a quarterly basis, based on the Financial Statements and Compliance Certificate delivered to Administrative Agent pursuant to Section 8.3(a) and (b). A failure to satisfy the Minimum Interest Coverage Test shall not be deemed a breach of any Loan Document nor constitute a Potential Default or an Event of Default.

     (b) Minimum Tangible Net Worth. Borrower shall not permit Consolidated Tangible Net Worth, as of the last day of any fiscal quarter of Borrower, to be less than the sum of (a) $2,716,220,000, plus (b) fifty percent (50%) of the amount of Net Proceeds from any Equity Issuance subsequent to March 31, 2005, plus (c) fifty percent (50%) of Cumulative Consolidated Net Income.

     2. Amendments to Credit Agreement and Other Loan Documents.

     (a) All references in the Loan Documents to the Credit Agreement shall henceforth include references to the Credit Agreement as modified and amended by this Amendment, and as may, from time to time, be further modified, amended, restated, extended, renewed, and/or increased.

     (b) Any and all of the terms and provisions of the Loan Documents are hereby amended and modified wherever necessary, even though not specifically addressed herein, so as to conform to the amendments and modifications set forth herein.

     3. Ratifications. Borrower (a) ratifies and confirms all provisions of the Loan Documents as amended by this Amendment, (b) ratifies and confirms that all guaranties and assurances, granted, conveyed, or assigned to the Credit Parties under the Loan Documents are not released, reduced, or otherwise adversely affected by this Amendment and continue to guarantee and assure full payment and performance of the present and future Obligation, and (c) agrees to perform such acts and duly authorize, execute, acknowledge, deliver, file, and record such additional documents and certificates as Administrative Agent may reasonably request in order to create, preserve and protect those guaranties and assurances.

EX-10.4

Exhibit 10.4

(Bilateral Form) (ISDA Agreements Subject)

CREDIT SUPPORT ANNEX

to the Schedule to the

ISDA MASTER AGREEMENT

dated as of July 18, 2007

between

BANK OF AMERICA, N.A.	and	CENTEX CORPORATION
(“Party A”)		(“Party B”)

This Annex supplements, forms part of, and is subject to, the above-referenced Agreement, is part of its Schedule and is a Credit Support Document under this Agreement with respect to each party.

Accordingly, the parties agree as follows:—

Paragraph 1. Interpretation

(a) Definitions and Inconsistency. Capitalized terms not otherwise defined herein or elsewhere in this Agreement have the meanings specified pursuant to Paragraph 12, and all references in this Annex to Paragraphs are to Paragraphs of this Annex. In the event of any inconsistency between this Annex and the other provisions of this Schedule, this Annex will prevail, and in the event of any inconsistency between Paragraph 13 and the other provisions of this Annex, Paragraph 13 will prevail.

(b) Secured Party and Pledgor. All references in this Annex to the “Secured Party” will be to either party when acting in that capacity and all corresponding references to the “Pledgor” will be to the other party when acting in that capacity; provided, however, that if Other Posted Support is held by a party, to this Annex, all references herein to that party as the Secured Party with respect to that Other Posted Support will be to that party as the beneficiary thereof and will not subject that support or that party as the beneficiary thereof to provisions of law generally relating to security interests and secured parties.

Paragraph 2. Security Interest

Each party, as the Pledgor, hereby pledges to the other party, as the Secured Party, as security for its Obligations, and grants to the Secured Party a first priority continuing security interest in, lien on and right of Set-off against all Posted Collateral Transferred to or received by the Secured Party hereunder. Upon the Transfer by the Secured Party to the Pledgor of Posted Collateral, the security interest and lien granted hereunder on that Posted Collateral will be released immediately and, to the extent possible, without any further action by either party.

Paragraph 3. Credit Support Obligations

(a) Delivery Amount. Subject to Paragraphs 4 and 5, upon a demand made by the Secured Party on or promptly following a Valuation Date, if the Delivery Amount for that Valuation Date equals or exceeds the Pledgor’s Minimum Transfer Amount, then the Pledgor will Transfer to the Secured Party Eligible Credit Support having a Value as of the date of Transfer at least equal to the applicable Delivery Amount (rounded pursuant to Paragraph 13). Unless otherwise specified in Paragraph 13, the “Delivery Amount” applicable to the Pledgor for any Valuation Date will equal the amount by which:

(i) the Credit Support Amount

exceeds

(ii) the Value as of that Valuation Date of all Posted Credit Support held by the Secured Party.

(b) Return Amount. Subject to Paragraphs 4 and 5, upon a demand made by the Pledgor on or promptly following a Valuation Date, if the Return Amount for that Valuation Date equals or exceeds the Secured Party’s Minimum Transfer Amount, then the Secured Party will Transfer to the Pledgor Posted Credit Support specified by the Pledgor in that demand having a Value as of the date of Transfer as close as practicable to the applicable Return Amount (rounded pursuant to Paragraph 13). Unless otherwise specified in Paragraph 13, the “Return Amount” applicable to the Secured Party for any Valuation Date will equal the amount by which:

(i) the Value as of that Valuation Date of all Posted Credit Support held by the Secured Party

exceeds

(ii) the Credit Support Amount.

“Credit Support Amount” means, unless otherwise specified in Paragraph 13, for any Valuation Date (i) the Secured Party’s Exposure for that Valuation Date plus (ii) the aggregate of all Independent Amounts applicable to the Pledgor, if any, minus (iii) all Independent Amounts applicable to the Secured Party, if any, minus (iv) the Pledgor’s Threshold; provided, however, that the Credit Support Amount will be deemed to be zero whenever the calculation of Credit Support Amount yields a number less than zero.

Paragraph 4.Conditions Precedent, Transfer Timing, Calculations and Substitutions

(a) Conditions Precedent. Each Transfer obligation of the Pledgor under Paragraphs 3 and 5 and of the Secured Party under Paragraphs 3, 4(d)(ii), 5 and 6(d) is subject to the conditions precedent that:

(i) no Event of Default, Potential Event of Default or Specified Condition has occurred and is continuing with respect to the other party; and

(ii) no Early Termination Date for which any unsatisfied payment obligations exist has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the other party.

(b) Transfer Timing. Subject to Paragraphs 4(a) and 5 and unless otherwise specified, if a demand for the Transfer of Eligible Credit Support or Posted Credit Support is made by the Notification Time, then the relevant Transfer will be made not later than the close of business on the next Local Business Day; if a demand is made after the Notification Time, then the relevant Transfer will be made not later than the close of business on the second Local Business Day thereafter.

(c) Calculations. All calculations of Value and Exposure for purposes of Paragraphs 3 and 6(d) will be made by the Valuation Agent as of the Valuation Time. The Valuation Agent will notify each party (or the other party, if the Valuation Agent is a party) of its calculations not later than the Notification Time on the Local Business Day following the applicable Valuation Date (or in the case of Paragraph 6(d), following the date of calculation).

(d)Substitutions.

(i) Unless otherwise specified in Paragraph 13, upon notice to the Secured Party specifying the items of Posted Credit Support to be exchanged, the Pledgor may, on any Local Business Day, Transfer to the Secured Party substitute Eligible Credit Support (the “Substitute Credit Support”); and

(ii) subject to Paragraph 4(a), the Secured Party will Transfer to the Pledgor the items of Posted Credit Support specified by the Pledgor in its notice not later than the Local Business Day following the date on which the Secured Party receives the Substitute Credit Support, unless otherwise specified in Paragraph 13 (the “Substitution Date”); provided that the Secured Party will only be obligated to Transfer Posted Credit Support with a Value as of the date of Transfer of that Posted Credit Support equal to the Value as of that date of the Substitute Credit Support.

Paragraph 5. Dispute Resolution

If a party (a “Disputing Party”) disputes (I) the Valuation Agent’s calculation of a Delivery Amount or a Return Amount or (II) the Value of any Transfer of Eligible Credit Support or Posted Credit Support, then (1) the Disputing Party will notify the other party and the Valuation Agent (if the Valuation Agent is not the other party) not later than the close of business on the Local Business Day following (X) the date that the demand is made under Paragraph 3 in the case of (I) above or (Y) the date of Transfer in the case of (II) above, (2) subject to Paragraph 4(a), the appropriate party will Transfer the undisputed amount to the other party not later than the close of business on the Local Business Day following (X) the date that the demand is made under Paragraph 3 in the case of (I) above or (Y) the date of Transfer in the case of (II) above, (3) the parties will consult with each other in an attempt to resolve the dispute and (4) if they fail to resolve the dispute by the Resolution Time, then:

(i) In the case of a dispute involving a Delivery Amount or Return Amount, unless otherwise specified in Paragraph 13, the Valuation Agent will recalculate the Exposure and the Value as of the Recalculation Date by:

(A) utilizing any calculations of Exposure for the Transactions (or Swap Transactions) that the parties have agreed are not in dispute;

(B) calculating the Exposure for the Transactions (or Swap Transactions) in dispute by seeking four actual quotations at mid-market from Reference Market-makers for purposes of calculating Market Quotation, and taking the arithmetic average of those obtained; provided that if four quotations are not available for a particular Transaction (or Swap Transaction), then fewer than four quotations may be used for that Transaction (or Swap Transaction); and if no quotations are available for a particular Transaction (or Swap Transaction), then the Valuation Agent’s original calculations will be used for that Transaction (or Swap Transaction); and

(C) utilizing the procedures specified in Paragraph 13 for calculating the Value, if disputed, of Posted Credit Support.

(ii) In the case of a dispute involving the Value of any Transfer of Eligible Credit Support or Posted Credit Support, the Valuation Agent will recalculate the Value as of the date of Transfer pursuant to Paragraph 13.

Following a recalculation pursuant to this Paragraph, the Valuation Agent will notify each party (or the other party, if the Valuation Agent is a party) not later than the Notification Time on the Local Business Day following the Resolution Time. The appropriate party will, upon demand following that notice by the Valuation Agent or a resolution pursuant to (3) above and subject to Paragraphs 4(a) and 4(b), make the appropriate Transfer.

Paragraph 6. Holding and Using Posted Collateral

(a) Care of Posted Collateral. Without limiting the Secured Party’s rights under Paragraph 6(c), the Secured Party will exercise reasonable care to assure the safe custody of all Posted Collateral to the extent required by applicable law, and in any event the Secured Party will be deemed to have exercised reasonable care if it exercises at least the same degree of care as it would exercise with respect to its own property. Except as specified in the preceding sentence, the Secured Party will have no duty with respect to Posted Collateral, including, without limitation, any duty to collect any Distributions, or enforce or preserve any rights pertaining thereto.

(b)  Eligibility to Hold Posted Collateral; Custodians.

(i) General. Subject to the satisfaction of any conditions specified in Paragraph 13 for holding Posted Collateral, the Secured Party will be entitled to hold Posted Collateral or to appoint an agent (a “Custodian”) to hold Posted Collateral for the Secured Party. Upon notice by the Secured Party to the Pledgor of the appointment of a Custodian, the Pledgor’s obligations to make any Transfer will be discharged by making the Transfer to that Custodian. The holding of Posted Collateral by a Custodian will be deemed to be the holding of that Posted Collateral by the Secured Party for which the Custodian is acting.

(ii) Failure to Satisfy Conditions. If the Secured Party or its Custodian fails to satisfy any conditions for holding Posted Collateral, then upon a demand made by the Pledgor, the Secured Party will, not later than five Local Business Days after the demand, Transfer or cause its Custodian to Transfer all Posted Collateral held by it to a Custodian that satisfies those conditions or to the Secured Party if it satisfies those conditions.

(iii) Liability. The Secured Party will be liable for the acts or omissions of its Custodian to the same extent that the Secured Party would be liable hereunder for its own acts or omissions.

(c) Use of Posted Collateral. Unless otherwise specified in Paragraph 13 and without limiting the rights and obligations of the parties under Paragraphs 3,4(d)(ii), 5, 6(d) and 8, if the Secured Party is not a Defaulting Party or an Affected Party with respect to a Specified Condition and no Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Secured Party, then the Secured Party will, notwithstanding Section 9-207 of the New York Uniform Commercial Code, have the right to:

(i) sell, pledge, rehypothecate, assign, invest, use, commingle or otherwise dispose of, or otherwise use in its business any Posted Collateral it holds, free from any claim or right of any nature whatsoever of the Pledgor, including any equity or right of redemption by the Pledgor; and

(ii) register any Posted Collateral in the name of the Secured Party, its Custodian or a nominee for either.

For purposes of the obligation to Transfer Eligible Credit Support or Posted Credit Support pursuant to Paragraphs 3 and 5 and any rights or remedies authorized under this Agreement, the Secured Party will be deemed to continue to hold all Posted Collateral and to receive Distributions made thereon, regardless of whether the Secured Party has exercised any rights with respect to any Posted Collateral pursuant to (i) or (ii) above.

(d)  Distributions and Interest Amount.

(i) Distributions. Subject to Paragraph 4(a), if the Secured Party receives or is deemed to receive Distributions on a Local Business Day, it will Transfer to the Pledgor not later than the following Local Business Day any Distributions it receives or is deemed to receive to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose).

(ii) Interest Amount. Unless otherwise specified in Paragraph 13 and subject to Paragraph 4(a), in lieu of any interest, dividends or other amounts paid or deemed to have been paid with respect to Posted Collateral in the form of Cash (all of which may be retained by the Secured Party), the Secured Party will Transfer to the Pledgor at the times specified in Paragraph 13 the Interest Amount to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose). The Interest Amount or portion thereof not Transferred pursuant to this Paragraph will constitute Posted Collateral in the form of Cash and will be subject to the security interest granted under Paragraph 2.

Paragraph 7. Events of Default

For purposes of Section 5(a)(iii)(l) of this Agreement, an Event of Default will exist with respect to a party if:

(i) that party fails (or fails to cause its Custodian) to make, when due, any Transfer of Eligible Collateral, Posted Collateral or the Interest Amount, as applicable, required to be made by it and that failure continues for two Local Business Days after notice of that failure is given to that party;

(ii) that party fails to comply with any restriction or prohibition specified in this Annex with respect to any of the rights specified in Paragraph 6(c) and that failure continues for five Local Business Days after notice of that failure is given to that party; or

(iii) that party fails to comply with or perform any agreement or obligation other than those specified in Paragraphs 7(i) and 7(ii) and that failure continues for 30 days after notice of that failure is given to that party.

Paragraph 8. Certain Rights and Remedies

(a) Secured Party’s Rights and Remedies. If at any time (1) an Event of Default or Specified Condition with respect to the Pledgor has occurred and is continuing or (2) an Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Pledgor, then, unless the Pledgor has paid in full all of its Obligations that are then due, the Secured Party may exercise one or more of the following rights and remedies:

(i) all rights and remedies available to a secured party under applicable law with respect to Posted Collateral held by the Secured Party;

(ii) any other rights and remedies available to the Secured Party under the terms of Other Posted Support, if any;

(iii) the right to Set-off any amounts payable by the Pledgor with respect to any Obligations against any Posted Collateral or the Cash equivalent of any Posted Collateral held by the Secured Party (or any obligation of the Secured Party to Transfer that Posted Collateral); and

(iv) the right to liquidate any Posted Collateral held by the Secured Party through one or more public or private sales or other dispositions with such notice, if any, as may be required under applicable law, free from any claim or right of any nature whatsoever of the Pledgor, including any equity or right of redemption by the Pledgor (with the Secured Party having the right to purchase any or all of the Posted Collateral to be sold) and to apply the proceeds (or the Cash equivalent thereof) from the liquidation of the Posted Collateral to any amounts payable by the Pledgor with respect to any Obligations in that order as the Secured Party may elect.

Each party acknowledges and agrees that Posted Collateral in the form of securities may decline speedily in value and is of a type customarily sold on a recognized market, and, accordingly, the Pledgor is not entitled to prior notice of any sale of that Posted Collateral by the Secured Party, except any notice that is required under applicable law and cannot be waived.

(b) Pledgor’s Rights and Remedies. If at any time an Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Secured Party, then (except in the case of an Early Termination Date relating to less than all Transactions (or Swap Transactions) where the Secured Party has paid in full all of its obligations that are then due under Section 6(e) of this Agreement):

(i) the Pledgor may exercise all rights and remedies available to a pledgor under applicable law with respect to Posted Collateral held by the Secured Party;

(ii) the Pledgor may exercise any other rights and remedies available to the Pledgor under the terms of Other Posted Support, if any;

(iii) the Secured Party will be obligated immediately to Transfer all Posted Collateral and the Interest Amount to the Pledgor; and

(iv) to the extent that Posted Collateral or the Interest Amount is not so Transferred pursuant to (iii) above, the Pledgor may:

(A) Set-off any amounts payable by the Pledgor with respect to any Obligations against any Posted Collateral or the Cash equivalent of any Posted Collateral held by the Secured Party (or any obligation of the Secured Party to Transfer that Posted Collateral); and

(B) to the extent that the Pledgor does not Set-off under (iv)(A) above, withhold payment of any remaining amounts payable by the Pledgor with respect to any Obligations, up to the Value of any remaining Posted Collateral held by the Secured Party, until that Posted Collateral is Transferred to the Pledgor.

(c) Deficiencies and Excess Proceeds. The Secured Party will Transfer to the Pledgor any proceeds and Posted Credit Support remaining after liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b) after satisfaction in full of all amounts payable by the Pledgor with respect to any Obligations; the Pledgor in all events will remain liable for any amounts remaining unpaid after any liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b).

(d) Final Returns. When no amounts are or thereafter may become payable by the Pledgor with respect to any Obligations (except for any potential liability under Section 2(d) of this Agreement), the Secured Party will Transfer to the Pledgor all Posted Credit Support and the Interest Amount, if any.

Paragraph 9. Representations

Each party represents to the other party (which representations will be deemed to be repeated as of each date on which it, as the Pledgor, Transfers Eligible Collateral) that:

(i) it has the power to grant a security interest in and lien on any Eligible Collateral it Transfers as the Pledgor and has taken all necessary actions to authorize the granting of that security interest and lien;

(ii) it is the sole owner of or otherwise has the right to Transfer all Eligible Collateral it Transfers to the Secured Party hereunder, free and clear of any security interest, lien, encumbrance or other restrictions other than the security interest and lien granted under Paragraph 2;

(iii) upon the Transfer of any Eligible Collateral to the Secured Party under the terms of this Annex, the Secured Party will have a valid and perfected first priority security interest therein (assuming that any central clearing corporation or any third-party financial intermediary or other entity not within the control of the Pledgor involved in the Transfer of that Eligible Collateral gives the notices and takes the action required of it under applicable law for perfection of that interest); and

(iv) the performance by it of its obligations under this Annex will not result in the creation of any security interest, lien or other encumbrance on any Posted Collateral other than the security interest and lien granted under Paragraph 2.

Paragraph 10. Expenses

(a) General. Except as otherwise provided in Paragraphs 10(b) and 10(c), each party will pay its own costs and expenses in connection with performing its obligations under this Annex and neither party will be liable for any costs and expenses incurred by the other party in connection herewith.

(b) Posted Credit Support. The Pledgor will promptly pay when due all taxes, assessments or charges of any nature that are imposed with respect to Posted Credit Support held by the Secured Party upon becoming aware of the same, regardless of whether any portion of that Posted Credit Support is subsequently disposed of under Paragraph 6(c), except for those taxes, assessments and charges that result from the exercise of the Secured Party’s rights under Paragraph 6(c).

(c) Liquidation/Application of Posted Credit Support. All reasonable costs and expenses incurred by or on behalf of the Secured Party or the Pledgor in connection with the liquidation and/or application of any Posted Credit Support under Paragraph 8 will be payable, on demand and pursuant to the Expenses Section of this Agreement, by the Defaulting Party or, if there is no Defaulting Party, equally by the parties.

This interest will be calculated on the basis of daily compounding and the actual number of days elapsed.

Promptly following a demand made by a party, the other party will execute, deliver, file and record any financing statement, specific assignment or other document and take any other action that may be necessary or desirable and reasonably requested by that party to create, preserve, perfect or validate any security interest or lien granted under Paragraph 2, to enable that party to exercise or enforce its rights under this Annex with respect to Posted Credit Support or an Interest Amount or to effect or document a release of a security interest on Posted Collateral or an Interest Amount.

(c) Further Protection. The Pledgor will promptly give notice to the Secured Party of, and defend against, any suit, action, proceeding or lien that involves Posted Credit Support Transferred by the Pledgor or that could adversely affect the security interest and lien granted by it under Paragraph 2, unless that suit, action, proceeding or lien results from the exercise of the Secured Party’s rights under Paragraph 6(c).

(d) Good Faith and Commercially Reasonable Manner. Performance of all obligations under this Annex, including, but not limited to, all calculations, valuations and determinations made by either party, will be made in good faith and in a commercially reasonable manner.

Paragraph 6. Holding and Using Posted Collateral

(a) Care of Posted Collateral. Without limiting the Secured Party’s rights under Paragraph 6(c), the Secured Party will exercise reasonable care to assure the safe custody of all Posted Collateral to the extent required by applicable law, and in any event the Secured Party will be deemed to have exercised reasonable care if it exercises at least the same degree of care as it would exercise with respect to its own property. Except as specified in the preceding sentence, the Secured Party will have no duty with respect to Posted Collateral, including, without limitation, any duty to collect any Distributions, or enforce or preserve any rights pertaining thereto.

(b) Eligibility to Hold Posted Collateral; Custodians.

(i) General. Subject to the satisfaction of any conditions specified in Paragraph 13 for holding Posted Collateral, the Secured Party will be entitled to hold Posted Collateral or to appoint an agent (a “Custodian”) to hold Posted Collateral for the Secured Party. Upon notice by the Secured Party to the Pledgor of the appointment of a Custodian, the Pledgor’s obligations to make any Transfer will be discharged by making the Transfer to that Custodian. The holding of Posted Collateral by a Custodian will be deemed to be the holding of that Posted Collateral by the Secured Party for which the Custodian is acting.

(ii) Failure to Satisfy Conditions. If the Secured Party or its Custodian fails to satisfy any conditions for holding Posted Collateral, then upon a demand made by the Pledgor, the Secured Party will, not later than five Local Business Days after the demand, Transfer or cause its Custodian to Transfer all Posted Collateral held by it to a Custodian that satisfies those conditions or to the Secured Party if it satisfies those conditions.

(iii) Liability. The Secured Party will be liable for the acts or omissions of its Custodian to the same extent that the Secured Party would be liable hereunder for its own acts or omissions.

(c) Use of Posted Collateral. Unless otherwise specified in Paragraph 13 and without limiting the rights and obligations of the parties under Paragraphs 3, 4(d)(ii), 5, 6(d) and 8, if the Secured Party is not a Defaulting Party or an Affected Party with respect to a Specified Condition and no Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Secured Party, then the Secured Party will, notwithstanding Section 9-207 of the New York Uniform Commercial Code, have the right to:

(i) sell, pledge, rehypothecate, assign, invest, use, commingle or otherwise dispose of, or otherwise use in its business any Posted Collateral it holds, free from any claim or right of any nature whatsoever of the Pledgor, including any equity or right of redemption by the Pledgor; and

(ii) register any Posted Collateral in the name of the Secured Party, its Custodian or a nominee for either.

For purposes of the obligation to Transfer Eligible Credit Support or Posted Credit Support pursuant to Paragraphs 3 and 5 and any rights or remedies authorized under this Agreement, the Secured Party will be deemed to continue to hold all Posted Collateral and to receive Distributions made thereon, regardless of whether the Secured Party has exercised any rights with respect to any Posted Collateral pursuant to (i) or (ii) above.

(d) Distributions and Interest Amount.

(i) Distributions. Subject to Paragraph 4(a), if the Secured Party receives or is deemed to receive Distributions on a Local Business Day, it will Transfer to the Pledgor not later than the following Local Business Day any Distributions it receives or is deemed to receive to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose).

(ii) Interest Amount. Unless otherwise specified in Paragraph 13 and subject to Paragraph 4(a), in lieu of any interest, dividends or other amounts paid or deemed to have been paid with respect to Posted Collateral in the form of Cash (all of which may be retained by the Secured Party), the Secured Party will Transfer to the Pledgor at the times specified in Paragraph 13 the Interest Amount to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose). The Interest Amount or portion thereof not Transferred pursuant to this Paragraph will constitute Posted Collateral in the form of Cash and will be subject to the security interest granted under Paragraph 2.

Paragraph 7. Events of Default

For purposes of Section 5(a)(iii)(l) of this Agreement, an Event of Default will exist with respect to a party if:

(i) that party fails (or fails to cause its Custodian) to make, when due, any Transfer of Eligible Collateral, Posted Collateral or the Interest Amount, as applicable, required to be made by it and that failure continues for two Local Business Days after notice of that failure is given to that party;

(ii) that party fails to comply with any restriction or prohibition specified in this Annex with respect to any of the rights specified in Paragraph 6(c) and that failure continues for five Local Business Days after notice of that failure is given to that party; or

(iii) that party fails to comply with or perform any agreement or obligation other than those specified in Paragraphs 7(i) and 7(ii) and that failure continues for 30 days after notice of that failure is given to that party.

(i) all rights and remedies available to a secured party under applicable law with respect to Posted Collateral held by the Secured Party;

(ii) any other rights and remedies available to the Secured Party under the terms of Other Posted Support, if any;

Each party acknowledges and agrees that Posted Collateral in the form of securities may decline speedily in value and is of a type customarily sold on a recognized market, and, accordingly, the Pledgor is not entitled to prior notice of any sale of that Posted Collateral by the Secured Party, except any notice that is required under applicable law and cannot be waived.

(c) Deficiencies and Excess Proceeds. The Secured Party will Transfer to the Pledgor any proceeds and Posted Credit Support remaining after liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b) after satisfaction in full of all amounts payable by the Pledgor with respect to any Obligations; the Pledgor in all events will remain liable for any amounts remaining unpaid after any liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b).

(d) Final Returns. When no amounts are or thereafter may become payable by the Pledgor with respect to any Obligations (except for any potential liability under Section 2(d) of this Agreement), the Secured Party will Transfer to the Pledgor all Posted Credit Support and the Interest Amount, if any.

Paragraph 9. Representations

Each party represents to the other party (which representations will be deemed to be repeated as of each date on which it, as the Pledgor, Transfers Eligible Collateral) that:

(i) it has the power to grant a security interest in and lien on any Eligible Collateral it Transfers as the Pledgor and has taken all necessary actions to authorize the granting of that security interest and lien;

(iv) the performance by it of its obligations under this Annex will not result in the creation of any security interest, lien or other encumbrance on any Posted Collateral other than the security interest and lien granted under Paragraph 2.

Paragraph 4. Conditions Precedent, Transfer Timing, Calculations and Substitutions

(B) calculating the Exposure for the Transactions (or Swap Transactions) in dispute by seeking four actual quotations at mid-market from Reference Market-makers for purposes of calculating Market Quotation, and taking the arithmetic average of those obtained; provided that if four quotations are not available for a particular Transaction (or Swap Transaction), then fewer than four quotations may be used for that Transaction (or Swap Transaction); and if no quotations are available for a particular Transaction (or Swap Transaction), then the Valuation Agent’s original calculations will be used for that Transaction (or Swap Transaction); and

Paragraph 6. Holding and Using Posted Collateral

(a) Care of Posted Collateral. Without limiting the Secured Party’s rights under Paragraph 6(c), the Secured Party will exercise reasonable care to assure the safe custody of all Posted Collateral to the extent required by applicable law, and in any event the Secured Party will be deemed to have exercised reasonable care if it exercises at least the same degree of care as it would exercise with respect to its own property. Except as specified in the preceding sentence, the Secured Party will have no duty with respect to Posted Collateral, including, without limitation, any duty to collect any Distributions, or enforce or preserve any rights pertaining thereto.

(b) Eligibility to Hold Posted Collateral; Custodians.

(i) General. Subject to the satisfaction of any conditions specified in Paragraph 13 for holding Posted Collateral, the Secured Party will be entitled to hold Posted Collateral or to appoint an agent (a “Custodian”) to hold Posted Collateral for the Secured Party. Upon notice by the Secured Party to the Pledgor of the appointment of a Custodian, the Pledgor’s obligations to make any Transfer will be discharged by making the Transfer to that Custodian. The holding of Posted Collateral by a Custodian will be deemed to be the holding of that Posted Collateral by the Secured Party for which the Custodian is acting.

(ii) Failure to Satisfy Conditions. If the Secured Party or its Custodian fails to satisfy any conditions for holding Posted Collateral, then upon a demand made by the Pledgor, the Secured Party will, not later than five Local Business Days after the demand, Transfer or cause its Custodian to Transfer all Posted Collateral held by it to a Custodian that satisfies those conditions or to the Secured Party if it satisfies those conditions.

(iii) Liability. The Secured Party will be liable for the acts or omissions of its Custodian to the same extent that the Secured Party would be liable hereunder for its own acts or omissions.

(c) Use of Posted Collateral. Unless otherwise specified in Paragraph 13 and without limiting the rights and obligations of the parties under Paragraphs 3, 4(d)(ii), 5, 6(d) and 8, if the Secured Party is not a Defaulting Party or an Affected Party with respect to a Specified Condition and no Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Secured Party, then the Secured Party will, notwithstanding Section 9-207 of the New York Uniform Commercial Code, have the right to:

(i) sell, pledge, rehypothecate, assign, invest, use, commingle or otherwise dispose of, or otherwise use in its business any Posted Collateral it holds, free from any claim or right of any nature whatsoever of the Pledgor, including any equity or right of redemption by the Pledgor; and

(ii) register any Posted Collateral in the name of the Secured Party, its Custodian or a nominee for either.

For purposes of the obligation to Transfer Eligible Credit Support or Posted Credit Support pursuant to Paragraphs 3 and 5 and any rights or remedies authorized under this Agreement, the Secured Party will be deemed to continue to hold all Posted Collateral and to receive Distributions made thereon, regardless of whether the Secured Party has exercised any rights with respect to any Posted Collateral pursuant to (i) or (ii) above.

(d) Distributions and Interest Amount.

(i) Distributions. Subject to Paragraph 4(a), if the Secured Party receives or is deemed to receive Distributions on a Local Business Day, it will Transfer to the Pledgor not later than the following Local Business Day any Distributions it receives or is deemed to receive to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose).

(ii) Interest Amount. Unless otherwise specified in Paragraph 13 and subject to Paragraph 4(a), in lieu of any interest, dividends or other amounts paid or deemed to have been paid with respect to Posted Collateral in the form of Cash (all of which may be retained by the Secured Party), the Secured Party will Transfer to the Pledgor at the times specified in Paragraph 13 the Interest Amount to the extent that a Delivery Amount would not be created or increased by that Transfer, as calculated by the Valuation Agent (and the date of calculation will be deemed to be a Valuation Date for this purpose). The Interest Amount or portion thereof not Transferred pursuant to this Paragraph will constitute Posted Collateral in the form of Cash and will be subject to the security interest granted under Paragraph 2.

Paragraph 7. Events of Default

For purposes of Section 5(a)(iii)(1) of this Agreement, an Event of Default will exist with respect to a party if:

(i) that party fails (or fails to cause its Custodian) to make, when due, any Transfer of Eligible Collateral, Posted Collateral or the Interest Amount, as applicable, required to be made by it and that failure continues for two Local Business Days after notice of that failure is given to that party;

(ii) that party fails to comply with any restriction or prohibition specified in this Annex with respect to any of the rights specified in Paragraph 6(c) and that failure continues for five Local Business Days after notice of that failure is given to that party; or

(iii) that party fails to comply with or perform any agreement or obligation other than those specified in Paragraphs 7(i) and 7(ii) and that failure continues for 30 days after notice of that failure is given to that party.

Paragraph 8. Certain Rights and Remedies

(a) Secured Party’s Rights and Remedies. If at any time (1) an Event of Default or Specified Condition with respect to the Pledgor has occurred and is continuing or (2) an Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Pledgor, then, unless the Pledgor has paid in full all of its Obligations that are then due, the Secured Party may exercise one or more of the following rights and remedies:

(i) all rights and remedies available to a secured party under applicable law with respect to Posted Collateral held by the Secured Party;

(ii) any other rights and remedies available to the Secured Party under the terms of Other Posted Support, if any;

(iii) the right to Set-off any amounts payable by the Pledgor with respect to any Obligations against any Posted Collateral or the Cash equivalent of any Posted Collateral held by the Secured Party (or any obligation of the Secured Party to Transfer that Posted Collateral); and

(iv) the right to liquidate any Posted Collateral held by the Secured Party through one or more public or private sales or other dispositions with such notice, if any, as may be required under applicable law, free from any claim or right of any nature whatsoever of the Pledgor, including any equity or right of redemption by the Pledgor (with the Secured Party having the right to purchase any or all of the Posted Collateral to be sold) and to apply the proceeds (or the Cash equivalent thereof) from the liquidation of the Posted Collateral to any amounts payable by the Pledgor with respect to any Obligations in that order as the Secured Party may elect.

Each party acknowledges and agrees that Posted Collateral in the form of securities may decline speedily in value and is of a type customarily sold on a recognized market, and, accordingly, the Pledgor is not entitled to prior notice of any sale of that Posted Collateral by the Secured Party, except any notice that is required under applicable law and cannot be waived.

(b) Pledgor’s Rights and Remedies. If at any time an Early Termination Date has occurred or been designated as the result of an Event of Default or Specified Condition with respect to the Secured Party, then (except in the case of an Early Termination Date relating to less than all Transactions (or Swap Transactions) where the Secured Party has paid in full all of its obligations that are then due under Section 6(e) of this Agreement):

(i) the Pledgor may exercise all rights and remedies available to a pledgor under applicable law with respect to Posted Collateral held by the Secured Party;

(ii) the Pledgor may exercise any other rights and remedies available to the Pledgor under the terms of Other Posted Support, if any;

(A) Set-off any amounts payable by the Pledgor with respect to any Obligations against any Posted Collateral or the Cash equivalent of any Posted Collateral held by the Secured Party (or any obligation of the Secured Party to Transfer that Posted Collateral); and

(B) to the extent that the Pledgor does not Set-off under (iv)(A) above, withhold payment of any remaining amounts payable by the Pledgor with respect to any Obligations, up to the Value of any remaining Posted Collateral held by the Secured Party, until that Posted Collateral is Transferred to the Pledgor.

(c) Deficiencies and Excess Proceeds. The Secured Party will Transfer to the Pledgor any proceeds and Posted Credit Support remaining after liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b) after satisfaction in full of all amounts payable by the Pledgor with respect to any Obligations; the Pledgor in all events will remain liable for any amounts remaining unpaid after any liquidation, Set-off and/or application under Paragraphs 8(a) and 8(b).

(d) Final Returns. When no amounts are or thereafter may become payable by the Pledgor with respect to any Obligations (except for any potential liability under Section 2(d) of this Agreement), the Secured Party will Transfer to the Pledgor all Posted Credit Support and the Interest Amount, if any.

Paragraph 9. Representations

Each party represents to the other party (which representations will be deemed to be repeated as of each date on which it, as the Pledgor, Transfers Eligible Collateral) that:

(i) it has the power to grant a security interest in and lien on any Eligible Collateral it Transfers as the Pledgor and has taken all necessary actions to authorize the granting of that security interest and lien;

(iv) the performance by it of its obligations under this Annex will not result in the creation of any security interest, lien or other encumbrance on any Posted Collateral other than the security interest and lien granted under Paragraph 2.

Paragraph 10. Expenses

(a) General. Except as otherwise provided in Paragraphs 10(b) and 10(c), each party will pay its own costs and expenses in connection with performing its obligations under this Annex and neither party will be liable for any costs and expenses incurred by the other party in connection herewith.

(b) Posted Credit Support. The Pledgor will promptly pay when due all taxes, assessments or charges of any nature that are imposed with respect to Posted Credit Support held by the Secured Party upon becoming aware of the same, regardless of whether any portion of that Posted Credit Support is subsequently disposed of under Paragraph 6(c), except for those taxes, assessments and charges that result from the exercise of the Secured Party’s rights under Paragraph 6(c).

Paragraph 11. Miscellaneous

(a) Default Interest. A Secured Party that fails to make, when due, any Transfer of Posted Collateral or the Interest Amount will be obligated to pay the Pledgor (to the extent permitted under applicable law) an amount equal to interest at the Default Rate multiplied by the Value of the items of property that were required to be Transferred, from (and including) the date that Posted Collateral or Interest Amount was required to be Transferred to (but excluding) the date of Transfer of that Posted Collateral or Interest Amount. This interest will be calculated on the basis of daily compounding and the actual number of days elapsed.

(b) Further Assurances. Promptly following a demand made by a party, the other party will execute, deliver, file and record any financing statement, specific assignment or other document and take any other action that may be necessary or desirable and reasonably requested by that party to create, preserve, perfect or validate any security interest or lien granted under Paragraph 2, to enable that party to exercise or enforce its rights under this Annex with respect to Posted Credit Support or an Interest Amount or to effect or document a release of a security interest on Posted Collateral or an Interest Amount.

(c) Further Protection. The Pledgor will promptly give notice to the Secured Party of, and defend against, any suit, action, proceeding or lien that involves Posted Credit Support Transferred by the Pledgor or that could adversely affect the security interest and lien granted by it under Paragraph 2, unless that suit, action, proceeding or lien results from the exercise of the Secured Party’s rights under Paragraph 6(c).

(d) Good Faith and Commercially Reasonable Manner. Performance of all obligations under this Annex, including, but not limited to, all calculations, valuations and determinations made by either party, will be made in good faith and in a commercially reasonable manner.
