Act") (the "Exchange Notes"), for any and all of its outstanding 7 3/8% Senior
Subordinated Notes due 2014 (the "Outstanding Notes"), guaranteed by the
Guarantors, in integral multiples of $1,000 from the holders thereof. The
Outstanding Notes are unconditionally guaranteed (the "Outstanding Guarantees")

Offer, except that the Exchange Notes are freely transferable by holders thereof
(except as provided herein or in the Prospectus) and are not subject to any
covenant regarding registration under the Securities Act.

     Capitalized terms used but not defined herein shall have the same meaning
given them in the Prospectus.

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undersigned is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Outstanding Notes that were acquired
as a result of market-making activities or other trading activities, it
acknowledges that it will deliver a prospectus in connection with any resale of
such Exchange Notes; however, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. A broker-dealer may not
participate in the Exchange Offer with respect to Outstanding Notes acquired
other than as a result of market-making activities or other trading activities.
Any holder who is an "affiliate" of the Company or who has an arrangement or
understanding with respect to the distribution of the Exchange Notes to be
acquired pursuant to the Exchange Offer, or any broker-dealer who purchased
Outstanding Notes from the Company to resell pursuant to Rule 144A under the
Securities Act or any other available exemption under the Securities Act must
comply with the registration and prospectus delivery requirements under the
Securities Act.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the principal amount of the
Outstanding Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of all or any portion of the Outstanding Notes tendered
herewith in accordance with the terms and conditions of the Exchange Offer
(including, if the Exchange Offer is extended or amended, the terms and
conditions of any such extension or amendment), the undersigned hereby
exchanges, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to such Outstanding Notes as are being tendered
herewith. The undersigned hereby irrevocably constitutes and appoints the
Exchange Agent as its true and lawful agent and attorney-in-fact of the
undersigned (with full knowledge that the Exchange Agent also acts as the agent
of the Company, in connection with the Exchange Offer) to cause the Outstanding
Notes to be assigned, transferred and exchanged.

     The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the Outstanding Notes and to
acquire the Exchange Notes issuable upon the exchange of such tendered
Outstanding Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title to the tendered Outstanding
Notes, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim. The undersigned also warrants that it will,
upon request, execute and deliver any additional documents deemed by the
Exchange Agent or the Company to be necessary or desirable to complete the
exchange, assignment and transfer of the tendered Outstanding Notes or transfer
ownership of such Outstanding Notes on the account books maintained by the
book-entry transfer facility. The undersigned further agrees that acceptance of
any and all validly

                                        3


tendered Outstanding Notes by the Company and the issuance of Exchange Notes in
exchange therefor shall constitute performance in full by the Company of its
obligations under the Registration Rights Agreement dated as of October 29,
2004, among the Company, the guarantors named therein and Morgan Stanley & Co.
Incorporated, Citigroup Global Markets Inc., UBS Securities LLC, Bear, Sterns &
Co. Inc., Natexis Bleichroeder Inc., Sovereign Securities Corporation, LLC and
Daiwa Securities America Inc., as representatives of the placement agents named
in Schedule I to the corresponding Purchase Agreement (the "Registration Rights
Agreement"), and that the Company shall have no further obligations or
liabilities thereunder except as provided in Section 6 of such agreement. The
undersigned will comply with its obligations under the Registration Rights
Agreement. The undersigned has read and agrees to all terms of the Exchange
Offer.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Exchange Offer -- Conditions to the Exchange
Offer." The undersigned recognizes that as a result of these conditions (which
may be waived, in whole or in part, by the Company), as more particularly set
forth in the Prospectus, the Company may not be required to exchange any of the
Outstanding Notes tendered hereby and, in such event, the Outstanding Notes not
exchanged will be returned to the undersigned at the address shown above,
promptly following the expiration or termination of the Exchange Offer. In
addition, the Company may amend the Exchange Offer at any time prior to the
Expiration Date if any of the conditions set forth under "The Exchange
Offers -- Conditions to the Exchange Offer" occur.

     The undersigned understands that tenders of Outstanding Notes pursuant to
any one of the procedures described in the Prospectus and in the instructions
attached hereto will, upon the Company's acceptance for exchange of such
tendered Outstanding Notes, constitute a binding agreement between the
undersigned and the Company upon the terms and subject to the conditions of the
Exchange Offer.

     By tendering the Outstanding Notes and executing this Letter of
Transmittal, the undersigned represents that (1) the Exchange Notes acquired in
the exchange will be obtained in the ordinary course of business of the
undersigned, (2) the undersigned has no arrangement or understanding with any
person to participate in a distribution (within the meaning of the Securities
Act) of such Exchange Notes, (3) the undersigned is not an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act and (4) if the
undersigned or the person receiving such Exchange Notes, whether or not such
person is the undersigned, is not a broker-dealer, the undersigned represents
that it is not engaged in, and does not intend to engage in, a distribution of
the Exchange Notes. If the undersigned or the person receiving such Exchange
Notes, whether or not such person is the undersigned, is a broker-dealer that
will receive Exchange Notes for its own account in exchange for Outstanding
Notes that were acquired as a result of market-making activities or other
trading activities, it acknowledges that (1) it has not entered into any
arrangement or understanding with the Company or an affiliate of the Company to
distribute the Exchange Notes and (2) it will deliver a prospectus in connection
with any resale of such Exchange Notes; however, by so acknowledging and by
delivering a prospectus, the undersigned will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. If the undersigned is
a person in the United Kingdom, the undersigned represents that its ordinary
activities involve it in acquiring, holding, managing or disposing of
investments (as principal or agent) for the purposes of its business.

     An "affiliate" of the Company or any holder of Outstanding Notes tendering
its Outstanding Notes in the Exchange Offer with the intention to participate,
or for the purpose of participating, in a distribution of the Exchange Notes or
any broker-dealer that acquired the Outstanding Notes directly from the Company
and not as a result of market-making activities or other trading activities (i)
cannot rely on the position of the staff of the Securities and Exchange
Commission enunciated in its interpretive letter with respect to Exxon Capital
Holdings Corporation (available May 13, 1988), Morgan Stanley & Co. Incorporated
(available June 5, 1991) and Shearman & Sterling (available July 2, 1993) or
similar interpretive letters and (ii) absent an exemption under the Securities
Act, must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale of the Exchange Notes. Such
broker-dealers may not use the prospectus for the exchange offer in connection
with such resales.

     All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned, and every obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned. Tendered Outstanding Notes may be withdrawn at
any time prior to the Expiration Date in accordance with the terms of this
Letter of Transmittal. Except as stated in the Prospectus, this tender is
irrevocable.

                                        4


     Certificates for all Exchange Notes delivered in exchange for tendered
Outstanding Notes and any Outstanding Notes delivered herewith but not
exchanged, and registered in the name of the undersigned, shall be delivered to
the undersigned at the address shown below the signature of the undersigned.

     The undersigned, by completing the box entitled "Description of Outstanding
Notes Tendered Herewith" above and signing this letter, will be deemed to have
tendered the Outstanding Notes as set forth in such box.

                                  INSTRUCTIONS

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
    PROCEDURES.

     A holder of Outstanding Notes may tender the same by (i) properly
completing and signing this Letter of Transmittal or a facsimile hereof (all
references in the Prospectus to the Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with the
certificate or certificates, if applicable, representing the Outstanding Notes
being tendered and any required signature guarantees and any other documents
required by this Letter of Transmittal, to the Exchange Agent at its address set

DTC in accordance with DTC's Automated Tender Offer Program ("ATOP") and by
complying with applicable ATOP procedures with respect to the Exchange Offer.
DTC participants that are accepting the Exchange Offer should transmit their
acceptance to DTC, which will edit and verify the acceptance and execute a
book-entry delivery to the Exchange Agent's account at DTC. DTC will then send a
computer-generated message (an "Agent's Message") to the Exchange Agent for its
acceptance in which the holder of the Outstanding Notes acknowledges and agrees
to be bound by the terms of, and makes the representations and warranties
contained in, this Letter of Transmittal, the DTC participant confirms on behalf
of itself and the beneficial owners of such Outstanding Notes all provisions of
this Letter of Transmittal (including any representations and warranties)
applicable to it and such beneficial owner as fully as if it had completed the
information required herein and executed and transmitted this Letter of
Transmittal to the Exchange Agent.

     DELIVERY OF THE AGENT'S MESSAGE BY DTC WILL SATISFY THE TERMS OF THE
EXCHANGE OFFER AS TO EXECUTION AND DELIVERY OF A LETTER OF TRANSMITTAL BY THE
PARTICIPANT IDENTIFIED IN THE AGENT'S MESSAGE. DTC PARTICIPANTS MAY ALSO ACCEPT
THE EXCHANGE OFFER BY SUBMITTING A NOTICE OF GUARANTEED DELIVERY THROUGH ATOP.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE OUTSTANDING NOTES
AND ANY OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER, AND
EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED MADE ONLY WHEN
ACTUALLY RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. IF SUCH DELIVERY IS BY
MAIL, IT IS SUGGESTED THAT REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR OVERNIGHT OR HAND DELIVERY SERVICE BE USED. IN ALL CASES
SUFFICIENT TIME SHOULD BE ALLOWED TO PERMIT TIMELY DELIVERY. NO OUTSTANDING
NOTES OR LETTERS OF TRANSMITTAL SHOULD BE SENT TO THE COMPANY.

     Holders whose Outstanding Notes are not immediately available or who cannot
deliver their Outstanding Notes and all other required documents to the Exchange
Agent on or prior to the Expiration Date or comply with book-entry transfer
procedures on a timely basis must tender their Outstanding Notes pursuant to the
guaranteed delivery procedure set forth in the Prospectus. Pursuant to such
procedure: (i) such tender must be made by or through an Eligible Guarantor

registered, and, if applicable, the certificate numbers of the Outstanding Notes
to be tendered; and (iii) all tendered Outstanding Notes (or a confirmation of
any book-entry transfer of such Outstanding Notes into the Exchange Agent's
account at a book-entry transfer facility) as well as this Letter of Transmittal
and all other documents required by this Letter of Transmittal, must be received
by the Exchange Agent within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission, all as
provided in the Prospectus.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Outstanding Notes for exchange.

                                        8


2.  PARTIAL TENDERS; WITHDRAWALS.

     Tenders of Outstanding Notes will be accepted only in the principal amount
of $1,000 and integral multiples of $1,000. If less than the entire principal
amount of Outstanding Notes evidenced by a submitted certificate is tendered,
the tendering holder must fill in the aggregate principal amount of Outstanding
Notes tendered in the box entitled "Description of Outstanding Notes Tendered
Herewith." A newly issued certificate for the Outstanding Notes submitted but
not tendered will be sent to such holder as soon as practicable after the
Expiration Date. All Outstanding Notes delivered to the Exchange Agent will be
deemed to have been tendered unless otherwise clearly indicated.

     If not yet accepted, a tender pursuant to the Exchange Offer may be
withdrawn prior to the Expiration Date.

     To be effective with respect to the tender of Outstanding Notes, a written
notice of withdrawal must: (i) be received by the Exchange Agent at the address
for the Exchange Agent set forth above before the Company notifies the Exchange
Agent that it has accepted the tender of Outstanding Notes pursuant to the
Exchange Offer; (ii) specify the name of the person who tendered the Outstanding
Notes to be withdrawn; (iii) identify the Outstanding Notes to be withdrawn
(including the principal amount of such Outstanding Notes, or, if applicable,
the certificate numbers shown on the particular certificates evidencing such
Outstanding Notes and the principal amount of Outstanding Notes represented by
such certificates); (iv) include a statement that such holder is withdrawing its
election to have such Outstanding Notes exchanged; and (v) be signed by the
holder in the same manner as the original signature on this Letter of
Transmittal (including any required signature guarantee). The Exchange Agent
will return the properly withdrawn Outstanding Notes promptly following receipt
of notice of withdrawal. If Outstanding Notes have been tendered pursuant to the
procedure for book-entry transfer, any notice of withdrawal must specify the
name and number of the account at the book-entry transfer facility to be
credited with the withdrawn Outstanding Notes or otherwise comply with the
book-entry transfer facility's procedures. All questions as to the validity of
notices of withdrawals, including time of receipt, will be determined by the
Company, and such determination will be final and binding on all parties.

     Any Outstanding Notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the Exchange Offer. Any Outstanding Notes
which have been tendered for exchange but which are not exchanged for any reason
will be returned to the holder thereof without cost to such holder (or, in the
case of Outstanding Notes tendered by book-entry transfer into the Exchange
Agent's account at the book entry transfer facility pursuant to the book-entry
transfer procedures described above, such Outstanding Notes will be credited to
an account with such book-entry transfer facility specified by the holder)
promptly after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Outstanding Notes may be retendered by following one
of the procedures described under the caption "The Exchange Offer -- Procedures
for Tendering Outstanding Notes" in the Prospectus at any time prior to the
Expiration Date.

eligible guarantor institution which is a member of a firm of a registered
national securities exchange or of the National Association of Securities

amended (an "Eligible Guarantor Institution"). If Outstanding Notes are
registered in the name of a person other than the signer of this Letter of
Transmittal, the Outstanding Notes surrendered for exchange must be endorsed by,
or be accompanied by a written instrument or instruments of transfer or
exchange, in satisfactory form as determined by the Company, in its sole
discretion, duly executed by the registered holder with the signature thereon
guaranteed by an Eligible Guarantor Institution.

5.  TRANSFER TAXES.

     The Company shall pay all transfer taxes, if any, applicable to the
transfer and exchange of Outstanding Notes to it or its order pursuant to the
Exchange Offer, except in the case of deliveries of certificates for Outstanding
Notes for Exchange Notes that are to be registered or issued in the name of any
person other than the holder of Outstanding Notes tendered thereby. If a
transfer tax is imposed for any reason other than the transfer and exchange of
Outstanding Notes to the Company or its order pursuant to the Exchange Offer,
the amount of any such transfer taxes (whether imposed on the registered holder
or any other person) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exception therefrom is not submitted
herewith the amount of such transfer taxes will be billed directly to such
tendering holder.

6.  WAIVER OF CONDITIONS.

     The Company reserves the absolute right to waive, in whole or in part, any
of the conditions to the Exchange Offer set forth in the Prospectus.

7.  MUTILATED, LOST, STOLEN OR DESTROYED SECURITIES.

     Any holder whose Outstanding Notes have been mutilated, lost, stolen or
destroyed, should contact the Exchange Agent at the address indicated below for
further instructions.

8.  SUBSTITUTE FORM W-9

     Each holder of Outstanding Notes whose Outstanding Notes are accepted for
exchange (or other payee) is generally required to provide a correct taxpayer
identification number ("TIN") (e.g., the holder's Social Security or federal
employer identification number) and certain other information, on Substitute
Form W-9, which is provided under "Important Tax Information" below, and to
certify that the holder (or other payee) is not subject to backup withholding.

                                        10


Failure to provide the information on the Substitute Form W-9 may subject the
holder (or other payee) to a $50 penalty imposed by the Internal Revenue Service
and 28% federal income tax backup withholding on payments made in connection
with the Outstanding Notes. The box in Part 3 of the Substitute Form W-9 may be
checked if the holder (or other payee) has not been issued a TIN and has applied
for a TIN or intends to apply for a TIN in the near future. If the box in Part 3
is checked and a TIN is not provided by the time any payment is made in
connection with the Outstanding Notes, 28% of all such payments will be withheld
until a TIN is provided and, if a TIN is not provided within 60 days, such
withheld amounts will be paid over to the Internal Revenue Service.

9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal, may be
directed to the Exchange Agent at the address and telephone number set forth
above. In addition, all questions relating to the Exchange Offer, as well as
requests for assistance or additional copies of the Prospectus and this Letter
of Transmittal, may be directed to the Exchange Agent at the address and
telephone number indicated above.

10.  IRREGULARITIES.

     All questions as to the validity, form, eligibility (including time of
receipt), and acceptance of Letters of Transmittal or Outstanding Notes will be
resolved by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all Letters of Transmittal
or tenders that are not in proper form or the acceptance of which would, in the
opinion of the Company's counsel, by unlawful. The Company also reserves the
right to waive any irregularities or conditions of tender as to the particular
Outstanding Notes covered by any Letter of Transmittal or tendered pursuant to
such Letter of Transmittal. Neither the Company, the Exchange Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. The Company's interpretation of the terms and conditions of the
Exchange Offer shall be final and binding.

     IMPORTANT:  THIS LETTER OF TRANSMITTAL OR A FACSIMILE OR COPY THEREOF
(TOGETHER WITH CERTIFICATES OF OUTSTANDING NOTES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY
MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION

     Under U.S. federal income tax law, a holder of Outstanding Notes whose
Outstanding Notes are accepted for exchange may be subject to backup withholding
unless the holder provides [Citibank, N.A.], as Paying Agent (the "Paying
Agent"), through the Exchange Agent with either (i) such holder's correct
taxpayer identification number ("TIN") on Substitute Form W-9 attached hereto,
certifying (A) that the TIN provided on Substitute Form W-9 is correct (or that
such holder of Outstanding Notes is awaiting a TIN), (B) that the holder of
Outstanding Notes is not subject to backup withholding because (x) such holder
of Outstanding Notes is exempt from backup withholding, (y) such holder of
Outstanding Notes has not been notified by the Internal Revenue Service that he
or she is subject to backup withholding as a result of a failure to report all
interest or dividends or (z) the Internal Revenue Service has notified the
holder of Outstanding Notes that he or she is no longer subject to backup
withholding and (C) that the holder of Outstanding Notes is a U.S. person
(including a U.S. resident alien); or (ii) an adequate basis for exemption from
backup withholding. If such holder of Outstanding Notes is an individual, the
TIN is such holder's social security number. If the Paying Agent is not provided
with the correct TIN, the holder of Outstanding Notes may also be subject to
certain penalties imposed by the Internal Revenue Service.

     Certain holders of Outstanding Notes (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. However, exempt holders of Outstanding
Notes should indicate their exempt status on Substitute Form W-9. For example, a
corporation should complete the Substitute Form W-9, providing its TIN and
indicating that it is exempt from backup withholding. In order for a foreign
individual to qualify as an exempt recipient, the holder must submit a Form
W-8BEN, signed under penalties of perjury, attesting to that individual's exempt
status. A Form W-8BEN can be obtained from the Paying Agent. See the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for more instructions.
                                        11


     If backup withholding applies, the Paying Agent is required to withhold 28%
of any payments made to the holder of Outstanding Notes or other payee. Backup
withholding is not an additional tax. Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service, provided the required information is furnished.

     The box in Part 3 of the Substitute Form W-9 may be checked if the
surrendering holder of Outstanding Notes has not been issued a TIN and has
applied for a TIN or intends to apply for a TIN in the near future. If the box
in Part 3 is checked, the holder of Outstanding Notes or other payee must also
complete the Certificate of Awaiting Taxpayer Identification Number below in
order to avoid backup withholding. Notwithstanding that the box in Part 3 is
checked and the Certificate of Awaiting Taxpayer Identification Number is
completed, the Paying Agent will withhold 28% of all payments made prior to the
time a properly certified TIN is provided to the Paying Agent and, if the Paying
Agent is not provided with a TIN within 60 days, such amounts will be paid over
to the Internal Revenue Service.

     The holder of Outstanding Notes is required to give the Paying Agent the
TIN (e.g., social security number or employer identification number) of the
record owner of the Outstanding Notes. If the Outstanding Notes are in more than
one name or are not in the name of the actual owner, consult the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for additional guidance on which number to report.
