LETTER OF TRANSMITTAL IS COMPLETED.
   2
         Capitalized terms used but not defined herein shall have the same
meaning given them in the Prospectus (as defined below).  As used herein, the
term "holder" means a holder of Original Notes (as defined below), including
any participant ("DTC Participant") in the book-entry transfer facility system
of The Depository Trust Company ("DTC"), whose name appears on a security
position listing as the owner of the Original Notes.  As used herein, the term
"Certificates" means physical certificates representing Original Notes.

   
         To participate in the Exchange Offer (as defined below), holders must
tender by (a) book-entry transfer pursuant to the procedures set forth in the
Prospectus under "The Exchange Offer--How to Tender" or (b) forwarding
Certificates herewith.  Holders who are DTC Participants tendering by
book-entry transfer must execute such tender through the Automated Tender Offer
Program ("ATOP") of DTC.  A holder using ATOP should transmit its acceptance to
DTC on or prior to the Expiration Date (as defined in the Prospectus).  DTC
will verify such acceptance, execute a book-entry transfer of the tendered
Original Notes into the account of State Street Bank and Trust Company (the
"Exchange Agent") at DTC and then send to the Exchange Agent a book-entry
confirmation (as defined below), including an Agent's Message (as defined
below) confirming that DTC has received an express acknowledgment from such
holder that such holder has received and agrees to be bound by this Letter of
Transmittal and that the Issuer (as defined below) and the Guarantors (as
defined below) may enforce this Letter of Transmittal against such holder.  The
book-entry confirmation must be received by the Exchange Agent in order for the
tender relating thereto to be effective.  Book-entry transfer to DTC in
accordance with DTC's procedures does not constitute delivery of the book-entry
confirmation to the Exchange Agent.
    

         If the tender is not made through ATOP, Certificates, as well as this
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees, and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
at its address set forth herein on or prior to the Expiration Date in order for
such tender to be effective.

   
         Holders of Original Notes whose Certificates for such Original Notes
are not immediately available or who cannot deliver their Certificates and all
other required documents to the Exchange Agent on or prior to the Expiration
Date or who cannot complete the procedures for book-entry transfer on or prior
to the Expiration Date, must tender their Original Notes according to the
guaranteed delivery procedures set forth in "The Exchange Offer -- How to
Tender -- Guaranteed Delivery Procedures" in the Prospectus.
    

         DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE
EXCHANGE AGENT.

                                  INSTRUCTIONS
         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

         1.  BOOK-ENTRY TRANSFER; DELIVERY OF LETTER OF TRANSMITTAL AND
CERTIFICATES; GUARANTEED DELIVERY PROCEDURES.  To tender in the Exchange Offer,
holders must tender by (a) forwarding Certificates herewith or (b) book-entry
transfer pursuant to the procedures set forth in "The Exchange Offer -- How to
Tender" in the Prospectus.  Holders who are DTC Participants tendering by
book-entry transfer must execute such tender through DTC's ATOP system.  A
holder using ATOP should transmit its acceptance to DTC on or prior to the
Expiration Date.  DTC will verify such acceptance, execute a book-entry
transfer of the tendered Original Notes into the Exchange Agent's account at
DTC and then send to the Exchange Agent a book-entry confirmation, including an
Agent's Message confirming that DTC has received an express acknowledgment from
such holder that such holder has received and agrees to be bound by this Letter
of Transmittal and that the Guarantors and the Issuers may enforce this Letter
of Transmittal against such holder.  The book-entry confirmation must be
received by the Exchange Agent in order for the tender relating thereto to be
effective.  Book-entry transfer to DTC in accordance with DTC's procedures does
not constitute delivery of the book-entry confirmation to the Exchange Agent.

         If the tender is not made through ATOP, Certificates, as well as this
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees, and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
at its address set forth herein on or prior to the Expiration Date in order for
such tender to be effective.  The term "book-entry confirmation" means a timely
confirmation of a book-entry transfer of Original Notes into the Exchange
Agent's account at DTC.  The term "Agent's Message" means a message,
transmitted by DTC to and received by the Exchange Agent and forming a part of
a book-entry confirmation, which states that DTC has received an express
acknowledgment from the tendering participant, which acknowledgment states that
such participant has received and agrees to be bound by the Letter of
Transmittal (including the representations contained herein) and that the
Guarantors and the Issuers may enforce the Letter of Transmittal against such
participant.

         Holders who wish to tender their Original Notes and (i) whose
Certificates for Original Notes are not immediately available, (ii) who cannot
deliver their Original Notes, this Letter of Transmittal and all other required
documents to the Exchange Agent on or prior to the Expiration Date or (iii) who
cannot complete the procedures for delivery by book-entry transfer on or prior
to the Expiration Date, may tender their Original Notes by properly completing
and duly executing a Notice of Guaranteed Delivery pursuant to the guaranteed
delivery procedures set forth under in "The Exchange Offer -- How to Tender" in
the Prospectus.  Pursuant to such procedures: (i) such tender must be made by
or through an Eligible Institution (as defined below); (ii) a properly
completed and duly executed Notice of Guaranteed Delivery, substantially in the
form made available by the Issuers and the Guarantors, must be received by the
Exchange Agent on or prior to the Expiration Date; and (iii) the Certificates
(or a book-entry confirmation) representing all tendered Original Notes, in
proper form for transfer, together with a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other documents required by this Letter of Transmittal, must
be received by the Exchange Agent within five trading days after the date of
execution of such Notice of Guaranteed Delivery, all as provided in "The
Exchange Offer -- How to Tender" in the Prospectus.

         The Notice of Guaranteed Delivery must be delivered by hand, overnight
courier or mail, or transmitted by facsimile transmission, to the Exchange
Agent on or prior to the Expiration Date, and must include a guarantee by an
Eligible Institution in the form set forth in such notice.  For Original Notes
to be properly tendered pursuant to the guaranteed delivery procedure, the
Exchange Agent must receive a Notice of Guaranteed Delivery on or prior to the
Expiration Date.  As used herein and in the Prospectus, "Eligible Institution"
means a firm or other entity identified in Rule 17Ad-15 under the Exchange Act
as "an eligible guarantor institution," including (as such terms are defined
therein) (i) a bank; (ii) a broker, dealer, municipal securities broker or
dealer or government securities broker or dealer; (iii) a credit union; (iv) a
national securities exchange, registered securities association or clearing
agency; or (v) a savings association that is a participant in a Securities
Transfer Association.

         THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT.  AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED OR, IF DELIVERY
IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED IS
RECOMMENDED.  IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY ON OR PRIOR TO THE EXPIRATION DATE.

         Neither the Issuers nor the Guarantors will accept any alternative,
conditional or contingent tenders.  Each tendering holder, by book-entry
transfer through ATOP or execution of a Letter of Transmittal (or facsimile
thereof), waives any right to receive any notice of the acceptance of such
tender.

         2.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required if:

                 (i) this Letter of Transmittal is signed by the registered
         holder (which term, for purposes of this document, shall include any
         participant in DTC whose name appears on a security position listing
         as the owner of the Original Notes) of Original Notes tendered
         herewith, unless such holder has completed either the box entitled
         "Special Issuance Instructions" or the box entitled "Special Delivery
         Instructions" above; or

                 (ii) such Original Notes are tendered for the account of a
         firm that is an Eligible Institution.

         In all other cases, an Eligible Institution must guarantee the
signature on this Letter of Transmittal.  See Instruction 5.

         3.  INADEQUATE SPACE.  If the space provided in the box captioned
"Description of Original Notes Tendered" is inadequate, the Certificate
number(s) and/or the principal amount of Original Notes and any other required
information should be listed on a separate signed schedule which is attached to
this Letter of Transmittal.

         4.  PARTIAL TENDERS AND WITHDRAWAL RIGHTS.  Tenders of Original Notes
will be accepted only in the principal amount of $1,000 (1 Original Note) and
integral multiples of $1,000 in excess thereof.  If less than all the Original
Notes evidenced by any Certificate submitted are to be tendered, fill in the
principal amount of Original Notes which are to be tendered in the applicable
box entitled "Principal Amount of Original Notes Tendered (If Less than All are
Tendered)."  In such case, a new Certificate for the remainder of the Original
Notes that were evidenced by your old Certificate will be sent to the holder of
the Original Notes, promptly after the Expiration Date unless the appropriate
boxes on this Letter of Transmittal are completed.  All Original Notes
represented by Certificates delivered to the Exchange Agent will be deemed to
have been tendered unless otherwise indicated.

         Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time on or prior to the Expiration Date.  In order for a
withdrawal to be effective, a written or facsimile transmission of such notice
of withdrawal must be received by the Exchange Agent at one of its addresses
set forth above or in the Prospectus on or prior to the Expiration Date.  Any
such notice of withdrawal must specify the name of the person who tendered the
Original Notes to be withdrawn, the aggregate principal amount of Original
Notes to be withdrawn and (if Certificates for Original Notes have been
tendered) the name of the registered holder of the Original Notes as set forth
on the Certificates for the Original Notes, if different from that of the
person who tendered such Original Notes.  If Certificates for the Original
Notes have been delivered or otherwise identified to the Exchange Agent, then
prior to the physical release of such Certificates, the tendering holder must
submit the serial numbers shown on the particular Certificates for the Original
Notes to be withdrawn and the signature on the notice of withdrawal must be
guaranteed by an Eligible Institution, except in the case of Original Notes
tendered for the account of an Eligible Institution.  If Original Notes have
been tendered pursuant to the procedures for book-entry transfer set forth
under "The Exchange Offer--How to Tender," the notice of withdrawal must
specify the name and number of the account at DTC to be credited with the
withdrawal of Original Notes, in which case a notice of withdrawal will be
effective if delivered to the Exchange Agent by written or facsimile
transmission on or prior to the Expiration Date.





                                       10
   11
Withdrawals of tenders of Original Notes may not be rescinded.  Original Notes
properly withdrawn will not be deemed validly tendered for purposes of the
Exchange Offer, but may be retendered at any subsequent time on or prior to the
Expiration Date by following any of the procedures described in the Prospectus
under "The Exchange Offer -- How to Tender."

         All questions as to the validity, form and eligibility (including time
of receipt) of such withdrawal notices will be determined by the Issuers and
the Guarantors, in their sole discretion, whose determination shall be final
and binding on all parties.  Neither the Issuers, the Guarantors, any
affiliates or assigns of the Issuers or the Guarantors, the Exchange Agent nor
any other person shall not be under any duty to give any notification of any
irregularities in any notice of withdrawal or incur any liability for failure
to give any such notification.  Any Original Notes which have been tendered but
which are withdrawn on or prior to the Expiration Date will be returned to the
holder thereof without cost to such holder promptly after withdrawal.

         5.  SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS.
If this Letter of Transmittal is signed by the registered holder of the
Original Notes tendered hereby, the signature must correspond exactly with the
name as written on the face of the Certificates without alteration, enlargement
or any change whatsoever.

         If any of the Original Notes tendered hereby are owned of record by
two or more joint owners, all such owners must sign this Letter of Transmittal.

         If any tendered Original Notes are registered in different names on
several Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.

         If this Letter of Transmittal or any Certificates or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and must submit proper
evidence satisfactory to the Issuers and the Guarantors, in their sole
discretion, of such persons' authority to so act.

         When this Letter of Transmittal is signed by the registered holder of
the Original Notes listed and transmitted hereby, no endorsement of
Certificates or separate bond powers are required unless Exchange Notes are to
be issued in the name of a person other than the registered holder.  Signatures
on such Certificates or bond powers must be guaranteed by an Eligible
Institution.

         If this Letter of Transmittal is signed by a person other than the
registered holder of the Original Notes, the Certificates must be endorsed or
accompanied by appropriate bond powers, signed exactly as the name of the
registered holder appears on the Certificates, and also must be accompanied by
such opinions of counsel, certifications and other information as the Issuers,
the Guarantors or the Exchange Agent may require in accordance with the
restrictions on transfer applicable to the Original Notes.  Signatures on such
Certificates or bond powers must be guaranteed by an Eligible Institution.

         6.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  If Exchange Notes are
to be issued in the name of a person other than the registered holder, or if
Exchange Notes are to be sent to someone other than the registered holder or to
an address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed.  Certificates for Original Notes not exchanged
will be returned by mail or, if tendered by book-entry transfer, by crediting
the account indicated above maintained at DTC unless the appropriate boxes on
this Letter of Transmittal are completed.  See Instruction 4.

         7.  IRREGULARITIES.  The Issuers and the Guarantors will determine, in
their sole discretion, all questions as to the form of documents, validity,
eligibility (including time of receipt) and acceptance for exchange of any
tender of Original Notes, which determination shall be final and binding on all
parties.  The Issuers and the Guarantors reserve the





                                       11
   12
absolute right to reject any and all tenders determined by either of them not
to be in proper form or the acceptance of which, or exchange for, may, in the
view of counsel to the Issuers or the Guarantors, be unlawful.  The Issuers and
the Guarantors also reserve the absolute right, subject to applicable law, to
waive any of the conditions of the Exchange Offer set forth in the Prospectus
under "The Exchange Offer -- Conditions to the Exchange Offer" or any
conditions or irregularity in any tender of Original Notes of any particular
holder whether or not similar conditions or irregularities are waived in the
case of other holders.  The Issuers' and the Guarantors' interpretation of the
terms and conditions of the Exchange Offer (including this Letter of
Transmittal and the instructions hereto) will be final and binding.  No tender
of Original Notes will be deemed to have been validly made until all
irregularities with respect to such tender have been cured or waived.  The
Issuers, the Guarantors, any Affiliates or assigns of the Issuers or the
Guarantors, the Exchange Agent or any other person shall not be under any duty
to give notification of any irregularities in tenders or incur any liability
for failure to give such notification.

         8.  QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES.
Questions and requests for assistance may be directed to the Exchange Agent at
its address and telephone number set forth on the front of this Letter of
Transmittal.  Additional copies of the Prospectus, the Notice of Guaranteed
Delivery and this Letter of Transmittal may be obtained from the Exchange Agent
or from your broker, dealer, commercial bank, trust company or other nominee.

         9.  WAIVER OF CONDITIONS.  The Issuers and Guarantors reserve the
absolute right to waive satisfaction of any or all conditions enumerated in the
Prospectus.

         10.  NO CONDITIONAL TENDERS.  No alternative, conditional, irregular
or contingent tenders will be accepted. All tendering holders of Original
Notes, by execution of this Letter of Transmittal, shall waive any right to
receive notice of the acceptance of their Original Notes for exchanges.

         Neither the Issuers, the Guarantors, the Exchange Agent nor any other
person is obligated to give notice of any defect or irregularity with respect
to any tender of Original Notes nor shall any of them incur any liability for
failure to give any such notice.

         11.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any Certificates
representing Original Notes have been lost, destroyed or stolen, the holder
should promptly notify the Exchange Agent.  The holder will then be instructed
as to the steps that must be taken in order to replace the Certificates.  This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen Certificates have been
followed.

         12.  SECURITY TRANSFER TAXES.  Holders who tender their Original Notes
for exchange will not be obligated to pay any transfer taxes in connection
therewith.  If, however, Exchange Notes are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the
Original Notes tendered, or if a transfer tax is imposed for any reason other
than the exchange of Original Notes in connection with the Exchange Offer, then
the amount of any such transfer tax (whether imposed on the registered holder
or any other persons) will be payable by the tendering holder.  If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted with
the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.

         IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF OR AGENT'S
MESSAGE IN LIEU THEREOF) AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY
THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.
