appoints each of (i) Teresa Bair, Vice President, Corporate Development & Legal

Company's Chief Financial Officer, as the undersigned's true and lawful
attorney-in-fact to:

    1.  prepare, execute in the undersigned's name and on the undersigned's
        behalf, and submit to the U.S. Securities and Exchange Commission (the
        "SEC") a Form ID, including amendments thereto, and any other documents
        necessary or appropriate to obtain codes and passwords enabling the
        undersigned to make electronic filings with the SEC of reports required
        by Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange
        Act") or any rule or regulation of the SEC;

    2.  execute for and on behalf of the undersigned, in the undersigned's

        benefit to, in the best interest of, or legally required by the
        undersigned, it being understood that the documents executed by such
        attorney-in-fact on behalf of the undersigned pursuant to this Power of
        Attorney shall be in such form and shall contain such terms and
        conditions as such attorney-in-fact may approve in his or her

    The undersigned hereby grants to such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
