The filing fee was calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory #5 for fiscal year 2009, issued March 11, 2009, by multiplying the transaction value by 0.0000558.

     “At 5:00 p.m., New York City time, on November 23, 2009, the Subsequent Offering Period of the Offer expired as scheduled. The Depositary has advised Parent that, as of the expiration of the Subsequent Offering Period, a total of approximately 22,407,901 Shares were validly tendered during the initial offering period and the Subsequent Offering Period taken together, representing approximately 90.8% of the Shares outstanding. The Purchaser has accepted for payment all Shares validly tendered and not validly withdrawn during the initial offering period and all Shares validly tendered during the Subsequent Offering Period.

     Pursuant to the terms of the Merger Agreement, Parent intends to consummate the Merger in accordance with the Merger Agreement later today.

Each of the remaining Shares (other than (i) Shares held by the Company as treasury stock or owned by Parent or the Purchaser or their respective subsidiaries, which will be cancelled and will cease to exist, and (ii) Shares owned by the Company’s stockholders who perfect their appraisal rights under the DGCL) will be converted into the right to receive $12.65 per Share net in cash, without interest and less any required withholding taxes, which is the same amount per Share that was paid in the Offer. Following the Merger, the Shares will no longer be listed on the NASDAQ Global Market.

Kimberly-Clark Corporation Completes Tender Offer for I-Flow Corporation

Acquisition Expected To Be Completed Today

DALLAS, TX (Nov. 24, 2009) — Kimberly-Clark Corporation (NYSE: KMB) today announced that the depositary for its tender offer for all the outstanding common stock of I-Flow Corporation (NASDAQ: IFLO) has advised that as of the expiration of the tender offer, stockholders of I-Flow tendered approximately 22,407,901 shares, representing approximately 90.8% of I-Flow’s outstanding shares. The tender offer expired at 5:00 p.m., New York City time, on November 23, 2009 and was not extended.

     According to the terms of the tender offer, all shares that were validly tendered have been accepted for payment. Kimberly-Clark intends to complete the acquisition of all remaining shares of I-Flow through a merger by close of business today. In the merger, each of the remaining shares of I-Flow common stock will be converted into the right to receive $12.65 per share, in cash, without interest and less any required withholding taxes, which is the same amount per share paid in the tender offer. The offer was conducted through Boxer Acquisition, Inc., a wholly owned subsidiary of Kimberly-Clark. As a result of the purchase of the shares in the tender offer, Boxer Acquisition has sufficient voting power to approve the merger without the affirmative vote of any other I-Flow stockholder. Following the completion of the merger, I-Flow will operate as part of Kimberly-Clark Health Care, and I-Flow’s common stock will no longer list on NASDAQ.
