ITEM 1.01. Entry Into a Material Definitive Agreement

Replacement Credit Facility

In connection with the consummation of the Merger (as defined below in Item 2.01), on November 2, 2007, Kyphon Inc. (“Kyphon”) entered into a Credit Agreement (the “Credit Agreement”) with The Bank of Tokyo Mitsubishi UFJ, Ltd. (the “Lender”). The Credit Agreement provides for a $300 million unsecured revolving credit facility (the “Facility”) maturing November 2, 2010. Kyphon may terminate or permanently reduce the commitments available under the Facility and prepay the Facility without premium or penalty at any time.

All amounts due to the Lender from Kyphon under the Credit Agreement, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise, are guaranteed by Medtronic, Inc. (“Medtronic”), which is the parent company of Kyphon, pursuant to a Guaranty made as of November 2, 2007 by Medtronic to the Lender.

The proceeds from the Facility were used to refinance all existing obligations under Kyphon’s current Credit Agreement dated as of January 18, 2007 and will be used to retire other existing debt obligations of Kyphon. In addition to certain initial fees, Kyphon is obligated to pay a commitment fee based on the total revolving commitment.

Each Revolving Loan (as defined under the Credit Agreement) shall be, at Kyphon’s request, either an Alternate Base Rate Loan or a Eurodollar Loan (each, as defined under the Credit Agreement).

The Credit Agreement contains customary representations and warranties of Kyphon as well as affirmative covenants regarding Kyphon. Upon the occurrence of an event of default under the Credit Agreement, the Lender could elect to declare all amounts outstanding under the Facility to be immediately due and payable. Events of default under the Credit Agreement include payment defaults, breaches of covenants, bankruptcy events and a change in control of Kyphon.

The foregoing description is qualified in its entirety by reference to the Credit Agreement, a copy of which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

Disc-O-Tech Vertebroplasty Transaction

On November 1, 2007, Kyphon entered into a definitive agreement to divest substantially all of the vertebroplasty spine-related assets and associated intellectual property rights of the Disc-O-Tech Parties (as defined below) encompassed by the Asset Purchase Agreement (Vertebroplasty Assets), dated as of December 20, 2006, by and among Kyphon, Disc-O-Tech Medical Technologies Ltd.

(together with Disc-O-Tech, the “Disc-O-Tech Parties”) relating to the sale of Disc-O-Tech’s Confidence™ product line used in the treatment of vertebral compression fractures. Under the terms of the divestiture agreement, the acquirer agreed to assume substantially all of Kyphon’s payment obligations under the vertebroplasty acquisition agreements. The divestiture agreement remains subject to regulatory clearances and other customary conditions.

Mott, Maureen L. Lamb, David M. Shaw, and Robert A Vandervelde. The acceleration became effective immediately prior to the consummation of the Merger.

The Board of Directors of Kyphon also approved certain amendments to Kyphon’s Variable Incentive Plan and Key Contributor Incentive Plan (together, the “Incentive Plans”). Payouts under the Incentive Plans are based on certain company and individual performance factors. Pursuant to these amendments, the Quarterly Payment Factor of the Variable Incentive Plan and the Individual Performance Factor and Company Performance Factor of the Key Contributor Incentive Plan were set at 100%, 100%, and 120%, respectively, for certain employees, including named executive officers.

Under the original terms of the Incentive Plans, a participant must be employed by Kyphon on the last day of the period for which a bonus payment is to be made.
