         The  undersigned  acknowledges  that it has  received  and reviewed the
Prospectus,  dated ______________ (the "Prospectus"),  of NBTY, Inc., a Delaware
corporation  (the  "Company"),  and this Letter of  Transmittal  (the "Letter of
Transmittal"), which together constitute the Company's offer to exchange any and
all  outstanding  8-5/8%  Senior  Subordinated  Notes  Due  2007,  Series A (the
"Original  Notes"),  of the Company  for a like  aggregate  principal  amount of
8-5/8% Senior  Subordinated Notes Due 2007, Series B (the "Exchange Notes," and,
together with the Original Notes, the "Notes"),  of the Company from the holders
("Holders")  thereof (the "Exchange  Offer").  The Original Notes were issued on
September 23, 1997 (the "Issue Date").

         For each  Original  Note  accepted  for  exchange,  the  Holder of such
Original Note will receive an Exchange  Note having a principal  amount equal to
that of the  surrendered  Original  Note.  The terms of the  Exchange  Notes are
identical in all material  respects to the Original  Notes,  except that (i) the
Exchange  Notes will bear a Series B  designation  and a different  CUSIP Number
from the Original Notes,  (ii) the issuance of the Exchange Notes will have been
registered under the Securities Act of 1933, as amended (the "Securities  Act"),
and,  therefore,  the  Exchange  Notes  will not bear  legends  restricting  the
transfer  thereof,  and (iii) holders of the Exchange Notes will not be entitled
to certain  registration  rights  relating to the Original  Notes.  The Exchange
Notes,  and the Original Notes remaining  outstanding  after the Exchange Offer,
mature on September 15, 2007.  Interest on the Exchange Notes issued pursuant to
the  Exchange  Offer will accrue from the last  interest  payment  date on which
interest was paid on the Original Notes  surrendered in exchange therefor or, if
no interest has been paid on the  Original  Notes,  from the Issue Date,  and is
payable  semi-annually  in  arrears on March 15 and  September  15 of each year,
commencing  March 15,  1998,  at the rate of 8-5/8%  per  annum.  Holders  whose
Original Notes are accepted for exchange will be deemed to have waived the right
to receive any interest  accrued on the Original Notes.  The Exchange Notes will
be  redeemable,  in whole or in part, at the option of the Company,  on or after
September 15, 2002 at the redemption  prices set forth in the  Prospectus,  plus
accrued  interest to the date of redemption.  See  "Description  of the Exchange
Notes" section of the Prospectus.

         The Company  reserves the right,  at any time or from time to time,  to
extend the Exchange Offer at its discretion, in which event the term "Expiration
Date"  shall  mean the  latest  time and date to  which  the  Exchange  Offer is
extended.  The  Company  will  notify the  Exchange  Agent (as  defined)  of any
extension by written notice and will mail to the registered  holders of Original
Notes an announcement  thereof,  each prior to 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date.

         The  Exchange  Offer  is not  conditioned  upon any  minimum  aggregate
principal  amount of Original  Notes being  tendered or accepted  for  exchange.
However,  the Exchange  Offer is subject to certain  conditions.  Please see the
Prospectus under the section entitled "The Exchange Offer - Conditions."

         The  Exchange  Offer is not being made to, nor will tenders be accepted
from or on behalf of, Holders of Original Notes in any jurisdiction in which the
making or acceptance of the Exchange  Offer would not be in compliance  with the
laws of such jurisdiction.

         This Letter of  Transmittal  is to be completed by a Holder of Original
Notes  either if  certificates  are to be  forwarded  herewith or if a tender of
certificates  for Original  Notes,  if  available,  is to be made by  book-entry
transfer to the account  maintained  by IBJ Schroder  Bank & Trust  Company (the
"Exchange  Agent") at the  Depository  Trust Company (the  "Book-Entry  Transfer
Facility")  pursuant  to the  procedures  set  forth  in "The  Exchange  Offer -
Procedures for Tendering"  section of the Prospectus.  Holders of Original Notes
whose certificates are not immediately  available,  or who are unable to deliver
their  certificates or  confirmation of the book-entry  tender of their Original
Notes into the Exchange Agent's account at the Book-Entry  Transfer  Facility (a
"Book-Entry  Confirmation")  and all other documents  required by this Letter of
Transmittal  to the  Exchange  Agent on or prior to the  Expiration  Date,  must
tender their Original Notes according to the guaranteed  delivery procedures set
forth in "The Exchange Offer - Guaranteed  Delivery  Procedures"  section of the
Prospectus.  See Instruction 1. Delivery of documents to the Book-Entry Transfer
Facility does not constitute delivery to the Exchange Agent.

         The undersigned  has completed the  appropriate  boxes below and signed
this Letter of  Transmittal  to indicate the action the  undersigned  desires to
take with respect to the Exchange Offer.

               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  aggregate  principal  amount of
Original Notes indicated  above.  Subject to, and effective upon, the acceptance
for exchange of the Original  Notes  tendered  hereby,  the  undersigned  hereby
sells,  assigns and  transfers  to, or upon the order of, the Company all right,
title and interest in and to such Original Notes as are being tendered hereby.

The undersigned hereby  irrevocably  constitutes and appoints the Exchange Agent
its agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company)  with respect to the tendered  Original  Notes
with the  full  power  of  substitution  to (i)  deliver  certificates  for such
Original Notes to the Company and deliver all accompanying evidences of transfer
and  authenticity  to, or upon the order of,  the  Company,  (ii)  present  such
Original  Notes for transfer on the books of the Company,  and (iii) receive for
the account of the Company all  benefits  and  otherwise  exercise all rights of
beneficial ownership of such Original Notes, all in accordance with the terms of
the Exchange  Offer.  The power of attorney  granted in this paragraph  shall be
deemed to be irrevocable  from and after the Expiration Date and coupled with an
interest.

The  undersigned  hereby  represents and warrants that the  undersigned has full
power and  authority to tender,  sell,  assign and  transfer the Original  Notes
tendered  hereby and that the Company will acquire good and  unencumbered  title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim when the same are accepted by the Company.  The
undersigned  hereby further represents that any Exchange Notes to be received by
the  undersigned  will be  acquired  in the  ordinary  course of business of the
undersigned,  that at the time of the  commencement of the Exchange  Offer,  the
undersigned has no arrangement or  understanding  with any person to participate
in the  distribution  (within the meaning of the Securities Act) of the Exchange
Notes in  violation of the  Securities  Act and that the  undersigned  is not an
"affiliate" (as defined in Rule 405 under the Securities Act) of the Company.

The  undersigned  agrees that  acceptance of any tendered  Original Notes by the
Company and the issuance of Exchange Notes in exchange  therefor will constitute
performance  in full by the Company of its  obligations  under the  Exchange and
Registration  Rights  Agreement  (as  defined  in the  Prospectus)  and that the
Company will have no further  obligations or liabilities  thereunder  (except in
limited circumstances).

The undersigned also acknowledges as follows:  This Exchange Offer is being made
in reliance  on  interpretations  by the staff of the  Securities  and  Exchange
Commission (the "Commission") set forth in certain "no-action" letters issued to
third parties and unrelated to the Company and the Exchange Offer,  and based on
such  interpretations,  the Company  believes  that the  Exchange  Notes  issued



pursuant to the Exchange Offer in exchange for the Original Notes may be offered
for resale,  resold and otherwise transferred by holders thereof (other than any
such holder that is an "affiliate" of the Company within the meaning of Rule 405
under  the  Securities  Act)  without   compliance  with  the  registration  and
prospectus  delivery  provisions  of the  Securities  Act,  provided  that  such
Exchange Notes are acquired in the ordinary course of such holders' business and
such holders have no arrangement or understanding with any person to participate
in the distribution of such Exchange Notes in violation of the provisions of the
Securities  Act. Any Holder who tenders in the Exchange Offer with the intention
to participate,  or for the purpose of  participating,  in a distribution of the
Exchange  Notes could not rely on the  position  of the staff of the  Commission
enunciated  in such  "no-action"  letters  and, in the  absence of an  exemption
therefrom,   must  comply  with  the   registration   and  prospectus   delivery
requirements  of the Securities Act in connection  with any resale  transaction.
Failure to comply with such  requirements  in such  instance  may result in such
Holder incurring  liability under the Securities Act for which the Holder is not
indemnified by the Company.  The  undersigned  acknowledges,  however,  that the
Company has not sought its own  no-action  letter and there can be no  assurance
that the staff of the Commission would make a similar determination with respect
to the Exchange Offer as in such other circumstances.

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  Original  Notes that were  acquired as a
result of market making or other trading activities,  the undersigned represents
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such Exchange Notes. By  acknowledging  that it
will  deliver and by  delivering a prospectus  meeting the  requirements  of the
Securities  Act in  connection  with any  resale  of such  Exchange  Notes,  the
undersigned  is not  deemed  to admit  that it is an  "underwriter"  within  the
meaning  of the  Securities  Act.  The  above-referenced  prospectus  may be the
Prospectus  relating  to the  Exchange  Offer  only  if it  contains  a plan  of
distribution  with  respect to such resale  transactions  (but need not name the
undersigned or disclose the amount of Exchange Notes held by the undersigned).

The undersigned will, upon request, execute and deliver any additional documents
deemed by the Company or the  Exchange  Agent to be  necessary  or  desirable to
complete  the sale,  assignment  and  transfer of the  Original  Notes  tendered
hereby.  All  authority  conferred  or agreed to be  conferred in this Letter of
Transmittal and every  obligation of the undersigned  hereunder shall be binding
upon the successors,  assigns,  heirs,  executors,  administrators,  trustees in
bankruptcy  and  legal  representatives  of the  undersigned  and  shall  not be
affected by, and shall survive, the death or incapacity of the undersigned. This
tender may be withdrawn only in accordance with the procedures set forth in "The
Exchange Offer - Withdrawal of Tenders" section of the Prospectus.

For  purposes  of this  Exchange  Offer,  the  Company  shall be  deemed to have
accepted validly  tendered  Original Notes when, as and if the Company has given
oral and written notice thereof to the Exchange Agent.

The undersigned  understands  that tenders of the Original Notes pursuant to any
one of the  procedures  described  under "The  Exchange  Offer - Procedures  for

                                       7


Tendering" in the Prospectus and in the  Instructions  hereto will  constitute a
binding agreement between the undersigned and the Company in accordance with the
terms and subject to the conditions set forth herein and in the Prospectus.

The  undersigned  recognizes that under certain  circumstances  set forth in the
Prospectus  under "The  Exchange  Offer -  Conditions"  the Company  will not be
required to accept for  exchange any of the Original  Notes  tendered.  Original
Notes not accepted for exchange or withdrawn  will be returned  (or, in the case
of  Original  Notes  tendered by  book-entry  transfer  through  the  Book-Entry
Transfer  Facility,  will  promptly be credited to an account  maintained at the
Book-Entry  Transfer  Facility),  without  expense,  to the  undersigned  at the
address set forth below  unless  otherwise  indicated  under  "Special  Delivery
Instructions" below as promptly as practicable after the Expiration Date.

Unless  otherwise  indicated  herein  in  the  box  entitled  "Special  Issuance
Instructions"  below,  please  deliver the Exchange  Notes (and, if  applicable,
substitute  certificates  representing Original Notes for any Original Notes not
exchanged)  in the  name of the  undersigned  or,  in the  case of a  book-entry
delivery of Original Notes, please credit the account indicated above maintained
at the Book-Entry Transfer Facility. Similarly, unless otherwise indicated under
the box entitled "Special Delivery Instructions" below, please send the Exchange
Notes (and, if applicable,  substitute certificates  representing Original Notes
for any Original  Notes not  exchanged) to the  undersigned at the address shown
above in the box entitled "Description of Original Notes."

THE UNDERSIGNED,  BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF ORIGINAL NOTES"
ABOVE AND SIGNING THIS LETTER OF  TRANSMITTAL,  WILL BE DEEMED TO HAVE  TENDERED
THE ORIGINAL NOTES AS SET FORTH IN SUCH BOX ABOVE.

     PROCEDURES.

         This Letter of  Transmittal  is to be  completed  by Holders  either if
certificates are to be forwarded  herewith or if tenders are to be made pursuant
to the procedures for delivery by book-entry transfer set forth in "The Exchange
Offer - Procedures for Tendering"  section of the Prospectus.  Certificates  for
all physically tendered Original Notes, or Book-Entry Confirmation,  as the case
may be, as well as a properly  completed and duly executed Letter of Transmittal
(or manually signed facsimile  hereof) and any other documents  required by this
Letter of Transmittal, must be received by the Exchange Agent at the address set
forth herein on or prior to the  Expiration  Date, or the tendering  holder must
comply with the guaranteed delivery procedures set forth below.

         Holders  whose  certificates  for  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 procedure for  book-entry  transfer on a timely basis,  may
tender their Original Notes pursuant to the guaranteed  delivery  procedures set
forth in "The Exchange Offer - Guaranteed  Delivery  Procedures"  section of the
Prospectus.  Pursuant to such  procedures (i) such entry must be made through an
Eligible Institution, (ii) prior to the Expiration Date, the Exchange Agent must
receive from such Eligible  Institution  a properly  completed and duly executed
Letter  of  Transmittal  (or a  facsimile  thereof)  and  Notice  of  Guaranteed
Delivery, substantially in the form provided by the Company (by telegram, telex,
facsimile  transmission,  mail or hand  delivery),  setting  forth  the name and

tendered,  setting forth the tender is being made thereby and guaranteeing  that
within three New York Stock Exchange  ("NYSE") trading days after the Expiration
Date,  the  certificates  for  all  physically  tendered  Original  Notes,  or a
Book-Entry  Confirmation,  and any other  documents  required  by the  Letter of
Transmittal  will be  deposited by the  Eligible  Institution  with the Exchange
Agent, and (iii) the certificates for all physically tendered Original Notes, in

tendering  holders,  but the  delivery  will be deemed  made only when  actually

received or confirmed by the Exchange Agent. If Original Notes are sent by mail,
it is  suggested  that  the  mailing  be made  sufficiently  in  advance  of the

York City time, on the Expiration Date.

         See "The Exchange Offer" section of the Prospectus.

2.       TENDER BY HOLDER; PARTIAL TENDERS.

         Only a Holder of Original  Notes may tender such Original  Notes in the
Exchange Offer.  Any beneficial owner whose Original Notes are registered in the
name of a broker,  dealer,  commercial  bank, trust company or other nominee and
who wishes to tender should contact the registered  Holder promptly and instruct
such  registered  Holder to tender on behalf of such  beneficial  owner. If such
beneficial  owner wishes to tender on such owner's own behalf,  such owner must,
prior to completing and executing this Letter of Transmittal and delivering such
owner's  Original  Notes,  either  make  appropriate  arrangements  to  register
ownership  of the  Original  Notes in such  owner's  name or  obtain a  properly
completed  bond power from the  registered  Holder.  The transfer of  registered
ownership may take considerable time.

         Tenders of Original  Notes will be accepted  only in  denominations  of
$1,000 or integral  multiples  thereof.  If less than all of the Original  Notes
evidenced by a submitted certificate are to be tendered, the tendering holder(s)
should fill in the aggregate  principal  amount of Original Notes to be tendered
in the box above  entitled  "Description  of Original  Notes - Principal  Amount
Tendered."  A reissued  certificate  representing  the  balance  of  nontendered
Original  Notes  will be sent to such  tendering  Holder  (except in the case of
book-entry  tenders),  unless otherwise  provided in the appropriate box on this
Letter of Transmittal  promptly  after the Expiration  Date. All of the Original
Notes  delivered  to the  Exchange  Agent  will be deemed to have been  tendered
unless otherwise indicated.

3.       SIGNATURES OF THIS LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
         GUARANTEE OF SIGNATURES.

         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 any change whatsoever.

         If any tendered Original Notes 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   copies  of  this  Letter  of   Transmittal  as  there  are  different
registrations of certificates.

         When this Letter of Transmittal  is signed by the registered  holder or
holders  of  the  Original  Notes  specified  herein  and  tendered  hereby,  no


                                       12


endorsements of certificates or separate bond powers are required.  If, however,
the Exchange Notes are to be issued, or any untendered  Original Notes are to be
reissued, to a person other than the registered holder, then endorsements of any
certificates transmitted hereby or separate bond powers are required. Signatures
on such certificate(s) must be guaranteed by an Eligible Institution.

         If this  Letter of  Transmittal  is signed by a person  other  than the
registered  holder or  holders  of any  certificate(s)  specified  herein,  such
certificate(s)  must be endorsed or accompanied by appropriate  bond powers,  in
either  case  signed  exactly as the name or names of the  registered  holder or
holders appear(s) on the  certificate(s)  and signatures on such  certificate(s)
must be guaranteed by an Eligible Institution.

         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,  unless waived by
the Company,  proper evidence  satisfactory to the Company of their authority to
so act must be submitted.

         ENDORSEMENTS ON  CERTIFICATES  FOR ORIGINAL NOTES OR SIGNATURES ON BOND
POWERS  REQUIRED BY THIS  INSTRUCTION  3 MUST BE  GUARANTEED BY A FIRM THAT IS A
MEMBER OF A REGISTERED  NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE NATIONAL
ASSOCIATION OF SECURITIES DEALERS, INC. OR BY A COMMERCIAL BANK OR TRUST COMPANY
HAVING  AN  OFFICE  OR   CORRESPONDENT   IN  THE  UNITED  STATES  (AN  "ELIGIBLE
INSTITUTION").

         SIGNATURES ON THIS LETTER OF  TRANSMITTAL  NEED NOT BE GUARANTEED BY AN
ELIGIBLE  INSTITUTION,  PROVIDED  THE  ORIGINAL  NOTES  ARE  TENDERED:  (i) BY A
REGISTERED  HOLDER OF ORIGINAL  NOTES (WHICH TERM,  FOR PURPOSES OF THE EXCHANGE
OFFER, INCLUDES ANY PARTICIPANT IN THE BOOK-ENTRY TRANSFER FACILITY SYSTEM WHOSE
NAME APPEARS ON A SECURITY POSITION LISTING AS THE HOLDER OF SUCH ORIGINAL NOTES
TENDERED) WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL ISSUANCE INSTRUCTIONS"
OR "SPECIAL  DELIVERY  INSTRUCTIONS" ON THIS LETTER OF TRANSMITTAL,  OR (ii) FOR
THE ACCOUNT OF AN ELIGIBLE INSTITUTION.

4.        SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.

         Tendering  holders of Original Notes should  indicate in the applicable
box the name and address to which Exchange Notes issued pursuant to the Exchange
Offer and/or substitute certificates evidencing Original Notes not exchanged are
to be  issued or sent,  if  different  from the name or  address  of the  person
signing this Letter of Transmittal. In the case of issuance in a different name,
the employer  identification  or social security number of the person named must
also be indicated.  Holders tendering Original Notes by book-entry  transfer may
request that Original Notes not exchanged be credited to such account maintained
at the Book-Entry  Transfer  Facility as such holder may designate hereon. If no
such  instructions are given, such Original Notes not exchanged will be returned
to the name or address of the person signing this Letter of Transmittal.


                                       13


5.        TAX IDENTIFICATION NUMBER

         Federal income tax law generally requires that a tendering holder whose
Original  Notes are accepted  for  exchange  must provide the Company (as payor)
with such holder's correct Taxpayer  Identification Number ("TIN") on Substitute
Form W-9 below,  which, in the case of a tendering  holder who is an individual,
is his or her social  security  number.  If the Company is not provided with the
current TIN or an adequate  basis for exemption,  such  tendering  holder may be
subject to a $50 penalty imposed by the Internal Revenue  Service.  In addition,
delivery to such  tendering  holder of  Exchange  Notes may be subject to backup
withholding in an amount equal to 31% of all reportable  payments made after the
exchange.  If  withholding  results in an  overpayment of taxes, a refund may be
obtained.

         Exempt  holders  of  Original  Notes  (including,   among  others,  all
corporations  and certain foreign  individuals)  are not subject to these backup
withholding  and  reporting   requirements.   See  the  enclosed  Guidelines  of
Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9
Guidelines") for additional instructions.

         To prevent backup withholding,  each tendering holder of Original Notes
must provide its correct TIN by completing the  "Substitute  Form W-9" set forth
below,  certifying  that the TIN  provided  is correct  (or that such  holder is
awaiting a TIN) and that (i) the holder is exempt  from backup  withholding,  or
(ii) the holder has not been notified by the Internal  Revenue Service that such
holder is subject to backup  withholding  as a result of a failure to report all
interest or dividends,  or (iii) the Internal  Revenue  Service has notified the
holder  that such  holder is no longer  subject  to backup  withholding.  If the
tendering holder of Original Notes is a nonresident  alien or foreign entity not
subject to backup  withholding,  such  holder  must give the Company a completed
Form W-8,  Certificate of Foreign  Status.  These forms may be obtained from the
Exchange  Agent.  If the Original  Notes are in more than one name or are not in
the name of the actual owner,  such holder should consult the W-9 Guidelines for
information  on which TIN to report.  If such holder  does not have a TIN,  such
holder should consult the W-9 Guidelines for instructions on applying for a TIN,
check the box in Part 2 of the  Substitute  Form W-9 and write  "applied for" in
lieu of its TIN. Note:  Checking this box and writing  "applied for" on the form
means that such holder has already applied for a TIN or that such holder intends
to apply for one in the near future.  If such holder does not provide its TIN to
the Company  within 60 days,  backup  withholding  will begin and continue until
such holder furnishes its TIN to the Company.

6.        TRANSFER TAXES.

         The Company  will pay all transfer  taxes,  if any,  applicable  to the
transfer of Original  Notes to it or its order  pursuant to the Exchange  Offer.
If, however,  Exchange Notes and/or substitute  Original Notes not exchanged are
to be delivered to, or are to be registered or issued in the name of, any person
other than the registered  holder of the Original Notes tendered  hereby,  or if
tendered  Original Notes are registered in the name of any person other than the

                                       14


person signing this Letter of  Transmittal,  or if a transfer tax is imposed for
any reason other than the transfer of Original 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  persons) will be payable by the
tendering holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted  herewith,  the amount of such transfer taxes will be
billed directly to such tendering holder.

         EXCEPT AS PROVIDED IN THIS  INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE ORIGINAL NOTES SPECIFIED IN THIS LETTER
OF TRANSMITTAL.

7.        WAIVER OF CONDITIONS.

         The Company reserves the absolute right to waive satisfaction of any or
all conditions enumerated in the Prospectus.

8.       NO CONDITIONAL TENDERS; WITHDRAWAL OF 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 exchange.

         Neither  the  Company,  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.

         Tenders of Original  Notes may be  withdrawn  at any time prior to 5:00
p.m.,  New York City time, on the  Expiration  Date.  See "The Exchange Offer --
Withdrawal of Tenders" in the  Prospectus for a description of the procedures to
be followed in such a situation.

9.       MUTILATED, LOST, STOLEN OR DESTROYED ORIGINAL NOTES.

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

10.      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  indicated
above.

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                          NUMBER ON SUBSTITUTE FORM W-9


Guidelines for Determining the Proper  Identification Number to Give the Payor -
Social  Security  numbers  have nine  digits  separated  by two  hyphens:  i.e.,
000-00-0000.  Employer identification numbers have nine digits separated by only
one hyphen: i.e.,  00-0000000.  Individual Taxpayer  Identification numbers have
nine digits and are used solely for tax purposes by individuals who are required
to have a  taxpayer  identification  number  but who do not have one and are not
eligible to obtain a Social Security number. The table below will help determine
the number to give the Payor.
