W I T N E S S E T H: WHEREAS, the Company has requested Merrill Lynch to act as the agent of the Company for the private placement to accredited investors of the Company's unsecured notes with maturities of up to 270 days from date of issue (the "Notes"). WHEREAS, the Notes will be represented by either individual note certificates ("Certificated Notes") or a master note of the Company. Individual Notes shall be issued substantially in the form of Exhibit A-1 or A-2 hereto, while master notes shall be issued substantially in the form of Exhibit B-1 or Exhibit B-2 hereto. Notes represented by a master note shall be referred to herein as "Book-Entry Notes." WHEREAS, Merrill Lynch has indicated its willingness to act as agent of the Company in the private placement of the Notes, subject to the satisfactory completion of such investigation and inquiry into the Company's business as Merrill Lynch deems appropriate under the circumstances. NOW THEREFORE, in consideration of the premises, the parties agree as follows: 1. Appointment as Placement Agent. (a) The Company appoints Merrill Lynch as one of its placement agents for the Notes and acknowledges that Merrill Lynch shall have the right to assist the Company in the placement of the Notes during the term of this Agreement in conjunction with Company's other placement agents. The Company agrees that during the period Merrill Lynch is acting as the Company's placement agent hereunder, the Company shall not, except through its co-placement agents, directly contact or solicit potential investors to purchase the Notes or engage any person or party to assist in the placement of Notes. While Merrill Lynch shall not have any obligation to purchase, as principal, Notes from the Company under any circumstances, Merrill Lynch may, from time to time, in its sole discretion purchase Notes, as principal, from the Company. (b) The Company and Merrill Lynch agree that any Notes the placement of which Merrill Lynch arranges or which are purchased by Merrill Lynch shall be placed or purchased by Merrill Lynch in reliance on the representations, warranties, covenants and agreements of the Company contained herein and on the terms and conditions and in the manner provided herein. (c) The Notes will be issued pursuant to an issuing and paying agency agreement (the "Issuing and Paying Agreement ") between Chase Manhattan Bank, as issuing and paying agent (the "Issuing and Paying Agent") and the Company. The Company will not amend the Issuing and Paying Agency Agreement without giving Merrill Lynch prior notice and a copy of such amendment. The Notes will be issued in such face or principal amounts (but not less than $250,000 each), and will bear such interest rates (if interest-bearing), or will be sold at such discounts, from their face amounts, as shall be mutually agreed to by the Company and Merrill Lynch at the time of each proposed purchase or placement. (d) Merrill Lynch shall have the right, in its discretion reasonably exercised, to reject any proposed purchase of Notes, in whole or in part. (e) The Company may instruct Merrill Lynch to suspend solicitation of purchases of Notes at any time. Upon receipt of such instruction, Merrill Lynch will forthwith suspend solicitation until such time as the Company has advised it that solicitation of purchases may be resumed. 2. Offers and Sales of the Notes. The offer and sale of the Notes by the Company is to be effected pursuant to the exemption from the registration requirements of the Securities Act of 1933, as amended (the "Act"), provided by Section 4(2) thereof and Regulation D thereunder, which exempt transactions by an issuer not involving any public offering. Offers and sales of the Notes by the Company will be made in accordance with the general provisions of Rule 506 under the Act. Merrill Lynch and the Company hereby establish the following procedures in connection with the offer and sale or resale of the Notes: (a) Offers and sales of the Notes will be made by the Company only to purchasers which qualify as accredited investors (as defined in Rule 501 (a) under the Act) (each such institutional purchaser being hereinafter called an "accredited investor"). Resales of the Notes will be made only to accredited investors or to institutional purchasers which are qualified institutional buyers (as defined in Rule 144A under the Act) (each such institutional purchaser being hereinafter called a "qualified institutional buyer"). No Notes will be offered to natural persons. (b) The Notes will be offered only by approaching prospective purchasers on an individual basis. The Notes will not be offered or sold by any means of general solicitation or general advertising. (c) In the case of a purchaser which is acting as a fiduciary for one or more third parties and which is not a bank as defined in Section 3(a)(2) of the Act or a savings and loan association or other institution as described in Section 3(a)(5) of the Act (each such purchaser, a "non-bank fiduciary"), each such third party will, in the judgment of Merrill Lynch, after due inquiry be an accredited investor or qualified institutional buyer. (d) No sale of the Notes to any one purchaser will be for less than $250,000 face amount and no Note will be issued in a smaller face amount. If the purchaser is a non-bank fiduciary acting on behalf of others, each person for whom it is acting must purchase at least $250,000 face amount of the Notes. (e) Each individual Note shall contain the legend set forth on the form of such Note attached as Exhibit A-1 or A-2 hereto, stating in effect that such Note has not been registered under the Act and that a resale or other transfer of such Note or any interest therein shall be made only (i) to Merrill Lynch or through Merrill Lynch to an institutional investor approved as an accredited investor or as a qualified institutional buyer by Merrill Lynch or (ii) to a qualified institutional buyer in a transaction made pursuant to Rule 144A under the Act. The purpose of this requirement is to ensure that Notes are resold or otherwise transferred only to accredited investors or qualified institutional buyers and not in a manner that might call into question the non-public offering character of the offer and sale of the Notes. (f) A Private Placement Memorandum will be made available to each purchaser or prospective purchaser together with any supplements to such Private Placement Memorandum which may have been prepared by the Company. The Private Placement Memorandum will contain a representation to the effect that the purchaser of a Note has hadan opportunity to ask questions of, and receive answers from, the Company concerning the offering of the Notes and to obtain copies of any of the Company Information (as defined below) that is referred to therein at no charge. The Private Placement Memorandum, including any Company Information referred to therein ishereby referred to as the "Disclosure Documents". (g) In addition to the other requirements of this Section 2, during any period the Company is not subject to the periodic filing requirements of the Securities Exchange Act of 1934, the Company agrees that, upon written request by any holder of the Notes, the Company will provide to the holder or to a prospective purchaser designated by the holder a copy of the Private Placement Memorandum and(i) the Company's most recent audited balance sheet that is as of a date less than 16 months old and audited statements of profit and loss and retained earnings for the 12 months preceding the date of the balance sheet, (ii) similar audited financial statements for the preceding two fiscal years or for such shorter period as the Company has been in operation and (iii) if the Company's most recent balance sheet is not as of a date less than six months old, additional statements of profit and loss and retained earnings (which may be unaudited) for the period from the date of such balance sheet to a date as of less than six months old. The purpose of this provision is to satisfy the conditions of paragraph (d)(4) of Rule 144A under the Act, so that resales of the Notes may be made to qualified institutional buyers pursuant to the exemption from registration provided by Rule 144A. The Private Placement Memorandum and each Note shall disclose that a holder of the Note may request, in writing, the information specified by paragraph (d)(4) of Rule 144A in connection with an intended sale or transfer of the Note pursuant to Rule 144A. (h) The Company agrees to cooperate with Merrill Lynch in the preparation of the Private Placement Memorandum and in amending it as from time to time may be necessary. Accordingly, the Company agrees to furnish Merrill Lynch with such information as requested to satisfy the conditions of paragraph (d)(4) of Rule 144A under the Act.The Company will furnish copies of its most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC"), each definitive proxy statement, each report on Form 10-Q and each report on Form 8-KAs long as any of the Notes are outstanding, the Company will provide Merrill Lynch with copies of all annual, interim, quarterly reports, proxy statements and registration statements which the Company files with the SEC, copies of all reports to the rating agencies, of all public releases or other publicly availableinformation (collectively, "the Company Information") in such quantities as Merrill Lynch may reasonably request. (i) Prior to any offer or sale of Notes, Merrill Lynch shall, with the cooperation of the Company, have the right to make such reasonable due diligence investigation of the business of the Company as is usual in the course of continuous offerings of debt instruments. The Company will immediately inform Merrill Lynch in writing of any material adverse change the condition, financial or otherwise, earnings, business affairs, results of operations or business prospects of the Company which (i) make or might make any statement in the Disclosure Documents false or misleading in any material respect or (ii) are not disclosed in such documents. In such event, Merrill Lynch shall not thereafter attempt to offer or place any of the Notes until the Company shall have prepared and furnished to Merrill Lynch, in such numbers as Merrill Lynch may require, supplements to, or amendments of, the Private Placement Memorandum reflecting any such material changes. Such supplements or amendments shall be prepared promptly by the Company. (j) The Company agrees to file a notice on Form D with the Securities and Exchange Commission (the "SEC") no later than fifteen days after the first issuance of Notes and at such other times as may be required pursuant to Rule 503 under the Act. (k) Merrill Lynch shall not be liable or responsible to the Company for any losses, damages or liabilities suffered or incurred by the Company, including any losses, damages or liabilities under the Act, arising from or relating to any resale or transfer of a Note other than for losses, damages or liabilities arising from Merrill Lynch's gross negligence or willful misconduct. 3.

(b) The financial statements included in the Disclosure Documents, if any, are and will be in accordance with the related books and records of the Company and are and will be complete and correct and fairly present in accordance with generally accepted accounting principles the financial position of the Company and its consolidated subsidiaries as at the dates set forth therein and the results of their operations for the periods set forth therein. Except as set forth in the Disclosure Documents, said financial statements have been prepared in conformity with generally accepted accounting principles applied on a basis which is consistent in all material respects during the periods involved. The supporting schedules, if any, included in the financial statements present fairly the information required to be stated therein as of the dates or for the periods indicated. (c) Since the respective dates as of which information is given in the Disclosure Documents, except as may otherwise be stated or contemplated therein or in any amendment or supplement thereto, there has not been any material adverse change in the condition, financial or otherwise, of the Company and its subsidiaries taken as a whole, or in the earnings, affairs or business prospects of the Company, and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business. (d) The Company (i) has been duly incorporated and is validly existing as a corporation in good standing under the laws of its jurisdiction of corporation, and (ii) has the requisite corporate power and authority to execute and deliver the Notes and to perform its obligations thereunder and to own its properties and conduct its business as described in the Disclosure Documents. (e) The Company is not in violation of its charter or by-laws or in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any material contract, indenture, mortgage, loan agreement or lease to which the Company is a party or by which it may be bound. The execution and delivery of this Agreement, the Issuing and Paying Agency Agreement and the Notes and the incurrence of the obligations and consummation of the transactions herein contemplated will not conflict with, or constitute a breach of or default under, its charter or by-laws of the Company or any material contract, indenture, mortgage, loan agreement or lease, to which each is a party or by which the Company may be bound, or any law, administrative regulation or court decree. (f) Each of this Agreement and the Issuing and Paying Agency Agreement has been duly authorized, executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company enforceable in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency or other similar laws relating to or affecting generally the enforcement of creditors' rights or by general equitable principles. (g) The Notes have been duly authorized for issuance, offer and sale as contemplated by the Agreement and, when issued and delivered against payment of the purchase price therefor, will constitute legal, valid and binding obligations of the Company enforceable in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency or other similar laws relating to or affecting generally the enforcement of creditors' rights or by general equitable principles.

(i) There are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject, other than as set forth in the Disclosure Documents and other than legal or governmental proceedings, which in each case will not have a material adverse effect on the business, financial condition, shareholders' equity or results of operations of the Company and its subsidiaries taken as a whole; and to the best of its knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others. (j) The Company is not an "investment company", or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended. (k) The offer, issuance, sale and delivery of the Notes in accordance with the terms of this Agreement will constitute exempt transactions under the Act pursuant to Section 4(2) thereof, and registration of the Notes under the Act will not be required; the Notes are eligible pursuant to Rule 144A under the Act. (l) The Notes rank at least pari passu with all other unsecured and unsubordinated indebtedness of the Company. (m) The Company agrees to maintain credit lines with Chemical Bank, as agent bank (as agent bank, the "Bank") which can be used to support payment on the Notes hereunder and agrees to report, and will cause the Bank to report, to Merrill Lynch on the status and usage of such credit lines, on a [quarterly] [monthly] basis. 4. Additional Representation and Warranty. Each acceptance by the Company of an offer for the purchase of Notes shall be deemed an affirmation by the Company that its representations and warranties set forth in Section 3 hereof are true and correct at the time of such acceptance, and an undertaking that such representations and warranties will be true and correct at the time of delivery to the purchaser or its agent of the Note or Notes relating to such acceptance, as though made at and as of such time (it being understood that insofar as such representations and warranties relate to the Private Placement Memorandum, such representations and warranties shall relate to the Private Placement Memorandum delivered to prospective purchasers of Notes at the time of such acceptance and at the time of such delivery of the Note or Notes relating to such acceptance, respectively.) 5. Covenants (a) The Company agrees that no future offer and sale of debt securities of the Company of any class will be made if, as a result of the doctrine of "integration" referred to in Rule 502 of Regulation D under the Act, Securities Act Release No. 6389 (March 8, 1982), Securities Act Releases Nos. 4434 (December 6, 1961), 4552 (November 6, 1962) and 4708 (July 9, 1964), and various "no-action" letters made available by the SEC, such offer and sale would call into question the entitlement of the Notes to the exemption from the registration requirements of the Act provided by Section 4(2) thereof. (b) The Company will endeavor, in cooperation with Merrill Lynch, to qualify the Notes for offer and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Company and Merrill Lynch shall determine, and will maintain such qualifications in effect for as long as may be required for the distribution of the Notes. The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Notes have been qualified as above provided. (c) No part of the proceeds of any Notes will be used in any transaction or for any purpose which violates the provisions of Regulations, G, T, U and X of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect.

If such failure occurred for any reason other than default by Merrill Lynch, the Company shall reimburse Merrill Lynch on an equitable basis for Merrill Lynch's loss of the use of such funds for the period such funds were credited to the Company's account. 8.
