Copies of the Offer to Purchase and the Letter of Transmittal are attached as Exhibits (a)(l) and (a)(2), respectively, to Schedule TO.

          The information in the Offer to Purchase, including all schedules and annexes thereto, is hereby expressly incorporated herein by reference. Capitalized terms used and not defined herein shall have the meanings set forth in the Offer to Purchase.

Offer to Purchase

           All references in the Offer to Purchase to "Monday, June 4, 2001" are deleted and replaced with "Monday, June 18, 2001".

Item 1. Summary Term Sheet

           The section of the Offer to Purchase entitled "Summary Term Sheet — Until what time can I withdraw previously tendered shares?" is amended to read in its entirety as follows:

           "You can withdraw shares at any time until the offer has expired. You may not, however, withdraw shares tendered during a subsequent offering period, if one is included. See "The Offer — Withdrawal Rights" and "The Offer — Terms of the Offer; Expiration Date."

Item 4. Terms of the Transaction

           The section of the Offer to Purchase entitled "The Offer — Terms of the Offer; Expiration Date" is amended by adding to the end of the first paragraph of that section the following phrase:

          "(other than any extension with respect to any Subsequent Offering Period, described below)."

          The section of the Offer to Purchase entitled "The Offer — Terms of the Offer; Expiration Date" is amended by adding immediately after the fourth paragraph of that section the following paragraphs:

          "After the expiration of the Offer, if all of the conditions to the Offer have been satisfied or waived, but not 100% of the Shares have been tendered, Purchaser may, in accordance with Rule 14d-11 under the Exchange Act, and subject to the conditions set forth in Rule 14d-11, include a subsequent offering period (a "Subsequent Offering Period"). A Subsequent Offering Period is an additional period of time from three business days to 20 business days in length, beginning after the Purchaser purchases Shares tendered in the Offer, during which stockholders may tender, but not withdraw, their Shares and receive the same price paid in the Offer. In addition, Purchaser may extend any initial Subsequent Offering Period by any period or periods, provided that the aggregate of the Subsequent Offering Period (including extensions thereof) is no more than 20 business days.

          No withdrawal rights apply to Shares tendered in a Subsequent Offering Period and no withdrawal rights apply during the Subsequent Offering Period with respect to Shares tendered in the Offer and accepted for payment. During a Subsequent Offering Period, the Purchaser will promptly purchase and pay for all Shares tendered at the same price paid in the Offer.

          Purchaser has not at this time made a decision to include or not to include a Subsequent Offering Period. Purchaser may make such decision in its sole discretion, and there is no assurance that Purchaser will or will not include such a Subsequent Offering Period. If Purchaser decides to provide for a Subsequent Offering Period it will make a public announcement thereof. Such announcement will be made no later than 9:00 a.m., New York City time, on the next business day after the Expiration Date."

          The first sentence of the fifth paragraph in the section of the Offer to Purchase entitled "The Offer — Terms of the Offer; Expiration Date" is amended by adding the following clause immediately after the word "amendment":

          "of the Offer or announcement of or extension of any Subsequent Offering Period"

          The sixth paragraph in the section of the Offer to Purchase entitled "The Offer — Terms of the Offer; Expiration Date" is amended by adding the following sentence to the end of that paragraph:

          "Notwithstanding the foregoing, if Purchaser provides for a Subsequent Offering Period it will immediately accept and promptly pay for all Shares as they are tendered during the Subsequent Offering Period."

          The section of the Offer to Purchase entitled "The Offer—Withdrawal Rights" is amended by adding the following paragraph at its end:

          "If Purchaser includes a Subsequent Offering Period (as described in more detail in "The Offer—Terms of the Offer; Expiration Date") following the Offer, no withdrawal rights will apply to Shares tendered in such Subsequent Offering Period or to Shares previously tendered in the Offer and accepted for payment."

Item 12.    Exhibits            Item 12 of the Schedule TO is hereby amended and supplemented by adding thereto the following:
