         The undersigned acknowledges receipt of the Prospectus and the related
Letter of Transmittal which describes the Company's offer (the "Exchange Offer")
to exchange $1,000 in principal amount of a new series of 115/8% Senior
Subordinated Notes due 2008, Series B (the "Exchange Notes") for each $1,000 in
principal amount of the Old Notes.

         The undersigned hereby tenders to the Company the aggregate principal
amount of Old Notes set forth below on the terms and conditions set forth in the
Prospectus and the related Letter of Transmittal pursuant to the guaranteed
delivery procedure set forth in the "The Exchange Offer--Guaranteed Delivery
Procedures" section in the Prospectus and the accompanying Letter of
Transmittal.

         The undersigned understands that no withdrawal of a tender of Old Notes
may be made on or after the expiration date of the Exchange Offer. The
undersigned understands that for a withdrawal of a tender of Old Notes to be
effective, a written notice of withdrawal that complies with the requirements of
the Exchange Offer must be timely received by the Exchange Agent at one of its
addresses specified on the cover of this Notice of Guaranteed Delivery prior to
the Expiration Date.

         The undersigned understands that the exchange of Old Notes for Exchange
Notes pursuant to the Exchange Offer will be made only after timely receipt by

Trust Company (the "Depositary" or "DTC")) and (ii) a Letter of Transmittal (or
facsimile thereof) with respect to such Old Notes, properly completed and duly
executed, with any required signature guarantees, this Notice of Guaranteed
Delivery and any other documents required by the Letter of Transmittal or a
properly transmitted Agent's Message. The term "Agent's Message" means a message
transmitted by the Depositary to, and received by, the Exchange Agent and
forming part of the confirmation of a book-entry transfer, which states that the
Depositary has received an express acknowledgment from each participant in the
Depositary tendering the Old Notes and that such participant has received the
Letter of Transmittal and agrees to be bound by the terms of the Letter of
Transmittal and the Company may enforce such agreement against such participant.

         All authority conferred or agreed to be conferred by this Notice of
Guaranteed Delivery shall not be affected by, and shall survive, the death or
incapacity of the undersigned, and every obligation of the undersigned under
this Notice of Guaranteed Delivery shall be binding upon the heirs, executors,
