Re: Registration Statement on Form S-3 Filed by Starbucks Corporation

Ladies and Gentlemen:

I am vice president, assistant general counsel and assistant secretary of Starbucks Corporation, a Washington corporation (the “Company”), and have acted in such capacity in connection with the authorization of the possible issuance and sale from time to time, on a delayed basis, by the Company of its debt securities (the “Debt Securities”), in one or more series, as contemplated by the Company’s Registration Statement on Form S-3 to which this opinion is an exhibit (as the same may be amended from time to time, the “Registration Statement”). The Debt Securities are to be issued from time to time pursuant to Rule 415 under the Securities Act of 1933 (the “Securities Act”). In addition, the Debt Securities are to be issued under the Indenture, dated as of August 23, 2007 (as amended, supplemented or otherwise modified from time to time, the “Indenture”), by and between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”).

In connection with the opinions expressed herein, I have examined such documents, records and matters of law as I have deemed relevant or necessary for purposes of such opinions. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, I am of the opinion that:

1. The Company is a corporation existing and in good standing under the laws of the State of Washington.

2. The execution and delivery of the Indenture by the Company has been authorized by all necessary corporate action of the Comapny.

3. The Debt Securities have been authorized by all necessary corporate action of the Company.

4. The execution, delivery, performance and compliance with the terms and provisions of the Indenture by the Company will not and does not, as applicable, violate the laws the State of Washington known to me to be generally applicable to transactions of this type (other than state securities or “blue sky” laws as to which I express no opinion in this paragraph) or the terms and provisions of the Company’s Restated Articles of Incorporation (the “Articles of Incorporation”) or Amended and Restated Bylaws (the “Bylaws”).
