Waters Corporation
34 Maple Street
Milford, Massachusetts 01757
     Re: Registration Statement on Form S-3
Ladies and Gentlemen:
     We are acting as counsel to Waters Corporation, a Delaware corporation (the “Company”), in connection with the Company’s registration statement on Form S-3 to be filed on or about May 26, 2006 (the “Registration Statement”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the proposed public offering of an indeterminate amount of the following securities of the Company: (i) shares of common stock, $0.01 par value per share (the “Common Stock”), (ii) shares of the Company’s preferred stock, par value $0.01 per share (the “Preferred Stock”), (iii) warrants to purchase shares of Common Stock and/or Preferred Stock (the “Warrants”), and (iv) shares of Common Stock and/or Preferred Stock issuable upon exercise of the Warrants. The Common Stock, the Preferred Stock and the Warrants are herein referred to as the “Registered Securities”. The Registered Securities may be offered and sold by the Company from time to time pursuant to Rule 415 under the Securities Act as set forth in the “base” prospectus which forms a part of the Registration Statement (the “Prospectus”), and as to be set forth in one or more supplements to the Prospectus that may be filed under the Securities Act. This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. Section 229.601(b)(5), in connection with the filing of the Registration Statement.
     As such counsel, we have reviewed the corporate proceedings taken by the Company with respect to the registration of the Registered Securities. We have also examined and relied upon originals or copies of such corporate records, documents, agreements or other instruments of the Company, and such certificates and records of public officials, and such other papers, as we have deemed necessary or appropriate in connection herewith. As to all matters of fact (including factual conclusions and characterizations and descriptions of purpose, intention or other state of mind) we have relied entirely upon certificates of officers of the Company, and have assumed, without independent inquiry, the accuracy of those certificates.
     For purposes of this opinion letter, we have assumed that:
     (i) the issuance, sale, amount, and terms of the Registered Securities to be offered from time to time will be duly authorized and established by proper action of the Board of Directors of the Company, and in accordance with the Second Amended and

Restated Certificate of Incorporation of the Company, as amended from time to time, the Amended and Restated By-laws of the Company as amended from time to time, and applicable Delaware law, and that, at the time of each such issuance and sale of such Registered Securities, the Company will continue to be validly existing and in good standing under the laws of the State of Delaware, with the requisite corporate power and authority to issue and sell all such Registered Securities at such time;
     (ii) any Warrants will be issued under one or more valid, binding, and enforceable warrant agreements (each a “Warrant Agreement”);
     (iii) any shares of Common Stock issued pursuant to the Registration Statement from time to time will not exceed the maximum authorized number of shares of Common Stock under the Second Amended and Restated Certificate of Incorporation of the Company, as the same may have been amended, minus that number of shares of Common Stock that may have been issued and are outstanding, or are reserved for issuance for other purposes, at such time; and
     (iv) any shares of Preferred Stock issued pursuant to the Registration Statement from time to time will not exceed the maximum authorized number of shares of Preferred Stock under the Second Amended and Restated Certificate of Incorporation of the Company, as the same may have been amended, minus that number of shares of Preferred Stock that may have been issued and are outstanding, or are reserved for issuance for other purposes, at such time.
     Subject to the limitations set forth below, we have made such examination of law as we have deemed necessary for the purposes of expressing the opinions set forth in this letter. Such opinions are limited solely to the General Corporation Law of the State of Delaware as applied by courts located in Delaware, the applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting those laws.
     Based upon the foregoing, we are of the opinion that:
     1. Following effectiveness of the Registration Statement, the shares of Common Stock registered under the Registration Statement, when duly authorized and issued against the full payment specified therefor, which must have a value not less than the par value thereof, will be validly issued, fully paid and nonassessable.
     2. Following effectiveness of the Registration Statement, the shares of Preferred Stock registered under the Registration Statement, when duly authorized and issued against the full payment specified therefor, which must have a value not less than the par value thereof, will be validly issued, fully paid and nonassessable.
     3. Following effectiveness of the Registration Statement, the Warrants registered under the Registration Statement, when duly authorized, executed and delivered against the payment specified therefor, and pursuant to a Warrant Agreement or agreements duly authorized, executed and delivered by the Company and the holder of the Warrants, will be validly issued.
