Item 1.01 Entry into a Material Definitive Agreement.

In connection with the proposed acquisition (the “Acquisition”) by McKesson Corporation (the “Company”) of US Oncology Holdings, Inc. (“US Oncology”), on November 23, 2010 the Company entered into a $2.0 billion one-year unsecured Senior Bridge Term Loan Agreement (the “Bridge Loan Agreement”) with Bank of America, N.A., as Administrative Agent, and the Lenders party thereto. Subject to the terms and conditions set forth in the Bridge Loan Agreement, up to two borrowings of term loans in an aggregate principal amount of up to $2.0 billion will be made available to the Company at its request to: (i) pay the merger consideration under the Agreement and Plan of Merger, dated as of November 1, 2010, by and among the Company, Utah Acquisition Corporation, a wholly owned subsidiary of the Company, US Oncology and Utah Stockholders’ Agent LLC, as the Stockholders’ Agent; (ii) repay certain indebtedness of US Oncology and its subsidiaries outstanding immediately prior to the closing of the Acquisition; and (iii) pay transaction costs associated with the Acquisition.

The Bridge Loan Agreement contains terms substantially similar to those contained in the Company’s existing revolving credit facility, dated as of June 8, 2007, which was filed with the Securities and Exchange Commission on June 14, 2007 as Exhibit 10.1 to the Company’s Current Report on Form 8-K. Similar to the revolving credit facility, borrowing under the Bridge Loan Agreement generally bears interest based upon either a prime rate or the London Interbank Offering Rate. The Bridge Loan Agreement includes, among other terms and conditions standard for transactions of this type, limitations (subject to specified exclusions) on the ability of the Company and its subsidiaries to create liens; engage in certain mergers and consolidations; and enter into swap contracts. In addition, the Bridge Loan Agreement requires that the Company maintain a total debt to total capitalization ratio of no greater than 56.5% throughout the term of the Bridge Loan Agreement. The Bridge Loan Agreement also includes mandatory prepayment provisions requiring the prepayment of the loans and (if applicable) reductions of undrawn commitments thereunder in an amount equal to the net cash proceeds from certain issuances of equity outside the ordinary course of business, certain property loss events, certain asset sales outside the ordinary course of business and the incurrence of certain indebtedness outside the ordinary course of business.

The foregoing description of the Company’s Bridge Loan Agreement does not purport to be complete and is qualified in its entirety by reference to the executed copy of the agreement attached hereto as Exhibit 10.1, which is incorporated herein by reference.

The Company entered into the Bridge Loan Agreement in order to provide funds for its purchase of US Oncology prior to the closing of the anticipated permanent financing, and to repay certain indebtedness of US Oncology and its subsidiaries. The Company expects that it will refinance all or part of the outstanding amounts under the Bridge Loan Agreement with longer-term debt financing prior to the end of the Bridge Loan Agreement’s one-year term.

Certain of the lenders party to the Bridge Loan Agreement and their respective affiliates have performed, and may in the future perform, various commercial banking, investment banking and other financial advisory services for the Company and its subsidiaries for which they have received, and will receive, customary fees and expenses.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
