ITEM 11. ADDITIONAL INFORMATION.
The following paragraph is added immediately before the sub-heading "Registration Rights" on page 34 of the Offer to Purchase:
Current SEC rules prohibit Parent, Purchaser or any of their affiliates from directly or indirectly purchasing or arranging to purchase any Common Stock of the Company except as part of the tender offer. This prohibition applies until the tender offer expires. Parent does not intend to exercise the Option at a time that would cause Parent to fail to comply with the aforementioned prohibition.
