Applicability From time to time Buyer and Seller may enter into transactions in which Seller agrees to transfer to Buyer certain securities and/or financial instruments ("Securities") against the transfer of funds by Buyer, with a simultaneous agreement by Buyer to transfer to Seller such Securities on demand, against the transfer of funds by Seller.

Definitions (a) "Act of Insolvency", with respect to either party (i) the commencement by such party as debtor of any case or proceeding under any bankruptcy, insolvency, reorganization, liquidation, dissolution or similar law, or such party seeking the appointment of a receiver, trustee, custodian or similar official for such party or any substantial part of its property; or (ii) the commencement of any such case or proceeding against such party, or another seeking such an appointment, which (A) is consented to or not timely contested by such party, (B) results in the entry of an order for relief, such an appointment or the entry of an order having a similar effect, or (C) is not dismissed within 15 days; or (iii) the making by a party of a general assignment for the benefit of creditors; or (iv) the admission in writing by a party of such party's inability to pay such party's debts as they become due; (b) "Additional Purchased Securities", Securities provided by Seller to Buyer pursuant to Paragraph 4(a) hereof; (c) "Income", with respect to any Security at any time, any principal thereof then payable and all interest, dividends or other distributions thereon; (d) "Market Value", with respect to any Securities as of any date, the price for such Securities on such date obtained from a generally recognized source agreed to by the parties or the most recent closing bid quotation from such a source, plus accrued Income to the extent not included therein (other than any Income transferred to Seller pursuant to Paragraph 6 hereof) as of such date (unless contrary to market practice for such Securities); PAGE (e) "Other Buyers", third parties that have entered into an agreement with Seller that is substantially similar to this Agreement; (f) "Pricing Rate", a rate equal to the Commercial Paper Composite rate for 90-day maturities provided by Merrill Lynch, Pierce, Fenner & Smith Incorporated (or, if such rate is not available, a substantially equivalent rate agreed to by Buyer and Seller) plus 25 basis points, which rate shall be adjusted on the first business day of each fiscal quarter and shall be in effect for the entirety such fiscal quarter; (g) "Purchase Price", the price at which Purchased Securities are transferred by Seller to Buyer; (h) "Purchased Securities", the Securities transferred by Seller to Buyer in a Transaction hereunder, and any Securities substituted therefor in accordance with Paragraph 9 hereof. The term "Purchased Securities" with respect to any Transaction at any time also shall include Additional Purchase Securities transferred pursuant to Paragraph 4(a) and shall exclude Securities returned pursuant to Paragraph 4(b); (i) "Repurchase Collateral Account", a book account maintained by Seller containing, among other Securities, the Purchased Securities; and (j) "Repurchase Price", for any Purchased Security, an amount equal to the Purchase Price paid by Buyer to Seller for such Purchased Security. 3. Transactions (a) A Transaction may be initiated by Buyer upon the transfer of the Purchase Price to Seller's account. Upon such transfer, Seller shall transfer to Buyer Purchased Securities having a Market Value equal to 103% of the Purchase Price. (b) Purchased Securities shall be held in custody for Buyer by Seller in the Repurchase Collateral Account. Seller shall indicate on its books for such account Buyer's ownership of the Purchased Securities. Upon reasonable request from Buyer, Seller shall provide Buyer with a complete list of Purchased Securities owned by Buyer. (c) Upon demand by Buyer or Seller, Seller shall repurchase from Buyer, and Buyer shall sell to Seller, for the Repurchase Price all or any part of the Purchased Securities then owned by Buyer. 2PAGE 4. Margin Maintenance (a) If at any time the aggregate Market Value of all Purchased Securities then owned by Buyer is less than 103% of the aggregate Repurchase Price for such Purchased Securities, then Seller shall transfer to Buyer additional Securities ("Additional Purchased Securities"), so that the aggregate Market Value of such Purchased Securities, including any such Additional Purchased Securities, will thereupon equal or exceed 103% of such aggregate Repurchase Price. (b) If at any time the aggregate Market Value of all Purchased Securities then owned by Buyer exceeds 103% of the aggregate Repurchase Price for such Purchased Securities, then Seller may transfer Purchased Securities to Seller, so that the aggregate Market Value of such Purchased Securities will thereupon not exceed 103% of such aggregate Repurchase Price. 5. Interest Payments If during any fiscal month Buyer owned Purchased Securities, then on the first day of the next following fiscal month Seller shall pay to Buyer an amount equal to the sum of the aggregate Repurchase Prices of the Purchased Securities owned by Buyer at the close of each day during the preceding fiscal month divided by the number of days in such month and the product multiplied by the Pricing Rate times the number of days in such month divided by 360. 6. Income Payments and Voting Rights Where a particular Transaction's term extends over an Income payment date on the Purchased Securities subject to that Transaction, Buyer shall, on the date such Income is payable, transfer to Seller an amount equal to such Income payment or payments with respect to any Purchased Securities subject to such Transaction. Seller shall retain all voting rights with respect to Purchased Securities sold to Buyer under this Agreement. 7. Security Interest Although the parties intend that all Transactions hereunder be sales and purchases and not loans, in the event any such Transactions are deemed to be loans, Seller shall be deemed to have pledged to Buyer as security for the performance by Seller of its obligations under each such Transaction and this Agreement, and shall be deemed to have granted to Buyer a security interest in, all of the Purchased Securities with respect to all Transactions hereunder and all proceeds thereof. 3PAGE 8. Payment and Transfer Unless otherwise mutually agreed, all transfers of funds hereunder shall be in immediately available funds. As used herein with respect to Securities, "transfer" is intended to have the same meaning as when used in Section 8-313 of the Massachusetts Uniform Commercial Code or, where applicable, in any federal regulation governing transfers of the Securities. 9. Substitution Buyer hereby grants Seller the authority to manage, in Seller's sole discretion, the Purchased Securities held in custody for Buyer by Seller in the Repurchase Collateral Account. Buyer expressly agrees that Seller may (i) substitute other Securities for any Purchased Securities and (ii) commingle Purchased Securities with other Securities held in the Repurchase Collateral Account. Substitutions shall be made by transfer to Buyer of such other Securities and transfer to Seller of the Purchased Securities for which substitution is being made. After substitution, the substituted Securities shall be deemed to be Purchased Securities. Securities which are substituted for Purchased Securities shall have a Market Value at the time of substitution equal to or greater than the Market Value of the Purchase Securities for which such Securities were substituted. 10.

(b) It is understood that either party's right to liquidate Securities delivered to it in connection with Transactions hereunder or to exercise any other remedies pursuant to Paragraph 11 hereof, is a contractual right to liquidate such Transaction 7PAGE as described in Sections 555 and 559 of Title 11 of the United States Code, as amended.
