other trading activities and acknowledges that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of

              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 Issuers the aggregate principal amount of
Senior Discount Debentures indicated above. Subject to, and effective upon, the
acceptance for exchange of the Senior Discount Debentures tendered hereby, the
undersigned hereby sells, assigns and transfers to, or upon the order of, the
Issuers all right, title and interest in and to such Senior Discount Debentures
as are being tendered hereby, and irrevocably constitutes and appoints the
Exchange Agent as agent and attorney-in-fact to cause the Senior Discount
Debentures to be assigned, transferred and exchanged.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Senior Discount
Debentures tendered hereby and to acquire Exchange Debentures issuable upon the
exchange of such tendered Senior Discount Debentures, and that the Issuers 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 Issuers. The undersigned hereby further represents
that (A) any Exchange Debentures acquired pursuant to the Exchange Offer are
being acquired in the ordinary course of business of the person receiving such
Exchange Debentures, whether or not such person is the holder; (B) it is not an
"affiliate" of the Issuers as defined in Rule 405 under the Securities Act of
1933, as amended (the "Securities Act"); (C) it is not participating in, and
does not intend to participate in, and has no arrangement or understanding with
any Person to participate in, a distribution of the Senior Discount Debentures
or the Exchange Debentures; and (D) if such holder is a broker or dealer
registered under the Exchange Act, it will receive the Exchange Debentures for
its own account in exchange for Senior Discount Debenture that were acquired as
a result of market-making activities or other trading activities. Each
broker-dealer referred to in clause (D) of the preceding sentence must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Debentures. The undersigned also warrants that acceptance of any
tendered Senior Discount Debentures by the Issuers and the issuance of Exchange
Debentures in exchange therefor shall constitute performance in full by the
Issuers of certain of its obligations under the Registration Rights Agreement.
 
    The undersigned also acknowledges that this Exchange Offer is being made in
reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, that the Exchange Debentures issued in exchange for the Senior Discount
Debentures pursuant to the Exchange Offer may be offered for resale, resold and
otherwise transferred by holders thereof (other than (i) any such holder that is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act and (ii) any broker-dealer that purchases Debentures from the
Issuers to resell pursuant to Rule 144A under the Securities Act ("Rule 144A")
or any other available exemption), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such
Exchange Debentures are acquired in the ordinary course of such holders'
business and such holders have no arrangement with any person to participate in
the distribution of such Exchange Debentures and are not participating in , and
do not intend to participate in, the distribution of the Exchange Debentures.
However, the Issuers do not intend to request the SEC to consider, and the SEC
has not considered the Exchange Offer in the context of a no-action letter and
there can be no assurance that the staff of the SEC would make a similar
determination with respect to the Exchange Offer as in other circumstances. The
undersigned acknowledges that any holder that is an affiliate of the Company, or
is participating in or intends to participate in or has any arrangement or
understanding with respect to the distribution of the Exchange Debentures to be
acquired pursuant to the Exchange Offer, (i) could not rely on the applicable
interpretations of the staff of the SEC and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. If the undersigned is not a
broker-dealer, the undersigned represents that it is not engaging in, and does
not intend to engage in, a distribution of Exchange Debentures. If the
undersigned is a broker-dealer that will receive Exchange Debentures for its own
account in exchange for Senior Discount Debentures, it represents that the
Senior Discount Debentures to be exchanged for the Exchange Debentures were
acquired by it as a result of market-making or other trading activities and
acknowledges that it will deliver

a prospectus in connection with any resale of such Exchange Debentures; 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.
 
    The undersigned, if a California resident, hereby further represents and
warrants that the undersigned (or the beneficial owner of the Senior Discount
Debentures tendered hereby, if not the undersigned) (i) is a bank, savings and
loan association, trust company, insurance company, investment company
registered under the Investment Company Act of 1940, pension or profit-sharing
trust (other than a pension or profit-sharing trust of the Company, a
self-employed individual retirement plan, or individual retirement account), or
a corporation which has a net worth on a consolidated basis according to its
most recent audited financial statement of not less than $14,000,000, and (ii)
is acquiring the Exchange Debentures for its own account for investment purposes
(or for the account of the beneficial owner of such Exchange Debentures for
investment purposes).
 
    The undersigned will, upon request, execute and deliver any additional
documents deemed by the Issuers to be necessary or desirable to complete the
sale, assignment and transfer of the Senior Discount Debentures tendered hereby.
All authority conferred or agreed to be conferred in this Letter 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 Rights" section of the Prospectus.

Instructions" below, please deliver the Exchange Debentures (and, if applicable,

Discount Debentures not exchanged) in the name of the undersigned or, in the

for delivery by book-entry transfer set forth in "The Exchange Offer --
Procedures for Tendering Senior Discount Debentures" section of the Prospectus
and an Agent's Message is not delivered. Certificates for all physically
tendered Senior Discount Debentures, or Book-Entry Confirmation, as the case may
be, as well as a properly completed and duly executed Letter (or manually signed
facsimile hereof) and any other documents required by this Letter, 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. Senior Discount Debentures tendered hereby
must be in denominations of principal amount of $1,000 and any integral multiple
thereof. The term "Agent's Message" means a message, transmitted by The
Depository Trust Company (the "Book-Entry Transfer Facility") and received by
the Exchange Agent and forming a part of the Book-Entry Confirmation, which
states that the Book-Entry Transfer Facility has received an express
acknowledgment from a participant tendering Senior Discount Debentures which are
subject to the Book-Entry Confirmation and that such participant has received
and agrees to be bound by this Letter and that the Issuers may enforce this
Letter against such participant.
 
    Noteholders whose certificates for Senior Discount Debentures 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 Senior Discount Debentures pursuant to the guaranteed delivery
procedures set forth in "The Exchange Offer -- Procedures for Tendering Senior
Discount Debentures" section of the Prospectus. Pursuant to such procedures, (i)
such tender 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 (or a facsimile thereof or an
Agent's Message in lieu hereof) and Notice of Guaranteed Delivery, substantially
in the form provided by the Issuers (by telegram, telex, facsimile transmission,
mail or hand delivery), setting forth the name and address of the holder of
Senior Discount Debentures and the amount of Senior Discount Debentures
tendered, stating that the tender is being made thereby and guaranteeing that
within three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Senior Discount Debentures, or a Book-Entry Confirmation,
and any other documents required by the Letter will be deposited by the Eligible
Institution with the Exchange Agent, and (iii) the certificates for all

Book-Entry Confirmation, as the case may be, and all other documents required by
this Letter, are received by the Exchange Agent within three NYSE trading days
after the date of execution of the Notice of Guaranteed Delivery.
 
    The method of delivery of this Letter, the Senior Discount Debentures and
all other required documents is at the election and risk of the tendering
holders, but the delivery will be deemed made only when actually received or
confirmed by the Exchange Agent. If Senior Discount Debentures are sent by mail,
it is suggested that the mailing be made sufficiently in advance of the
Expiration Date to permit delivery to the Exchange Agent prior to 5:00 p.m., New
York City time, on the Expiration Date.
 
    See "The Exchange Offer" section of the Prospectus.

certificate are to be tendered, the tendering holder(s) should fill in the
aggregate principal amount of Senior Discount Debentures to be tendered in the
box above entitled "Description of Senior Discount Debentures -- Principal
Amount Tendered." A reissued certificate representing the balance of nontendered
Senior Discount Debentures will be sent to such tendering holder, unless
otherwise provided in the appropriate box on this Letter, promptly after the
Expiration Date. All of the Senior Discount Debentures delivered to the Exchange
Agent will be deemed to have been tendered unless otherwise indicated.
 
3.  SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
    SIGNATURES.
 
    If this Letter is signed by the registered holder of the Senior Discount
Debentures 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 Senior Discount Debentures are owned of record by two or
more joint owners, all of such owners must sign this Letter.
 
    If any tendered Senior Discount Debentures are registered in different names
on several certificates, it will be necessary to complete, sign and submit as
many separate copies of this Letter as there are different registrations of
certificates.
 
    When this Letter is signed by the registered holder or holders of the Senior
Discount Debentures specified herein and tendered hereby, no endorsements of
certificates or separate bond powers are required. If, however, the Exchange
Debentures are to be issued, or any untendered Senior Discount Debentures 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 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 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 Issuers,
proper evidence satisfactory to the Issuers of their authority to so act must be
submitted.

BOND POWERS REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS
A MEMBER OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE
NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC., OR A CLEARING AGENCY, INSURED
CREDIT UNION, A SAVINGS ASSOCIATION OR A COMMERCIAL BANK OR TRUST COMPANY HAVING
AN OFFICE OR CORRESPONDENT IN THE UNITED STATES (EACH AN "ELIGIBLE
INSTITUTION").
 
    SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE INSTITUTION,
PROVIDED THE SENIOR DISCOUNT DEBENTURES ARE TENDERED: (I) BY A REGISTERED HOLDER
OF SENIOR DISCOUNT DEBENTURES (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 HOLDERS OF SUCH SENIOR DISCOUNT
DEBENTURES) WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL ISSUANCE
INSTRUCTIONS" OR "SPECIAL DELIVERY INSTRUCTIONS" ON THIS LETTER, OR (II) FOR THE
ACCOUNT OF AN ELIGIBLE INSTITUTION.
 
4.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.
 
    Tendering holders of Senior Discount Debentures should indicate in the
applicable box the name and address to which New Debentures issued pursuant to
the Exchange Offer and/or substitute certificates evidencing Senior Discount
Debentures not exchanged are to be issued or sent, if different from the name or
address of the person signing this Letter. 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 Senior Discount Debentures by book-entry transfer
may request that Senior Discount Debentures not exchanged be credited to such
account maintained at the Book-Entry Transfer Facility as such noteholder may
designate hereon. If no such instructions are given, such Senior Discount
Debentures not exchanged will be returned to the name or address of the person
signing this Letter.
 
5.  TAX IDENTIFICATION NUMBER.
 
    Federal income tax law generally requires that a tendering holder whose
Senior Discount Debentures are accepted for exchange must provide the Issuers
(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 Issuers are not
provided with the current TIN or an adequate basis for an 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 Debentures
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 Senior Discount Debentures (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 Senior Discount
Debentures 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 Senior Discount Debentures is a
nonresident alien or foreign entity not subject to backup withholding, such
holder must give the Issuers a completed Form W-8, Certificate of Foreign
Status. These forms may be obtained from the Exchange Agent. If the Senior
Discount Debentures 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.
Debenture: 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
Issuers within 60 days, backup withholding will begin and continue until such
holder furnishes its TIN to the Issuers.
 
6.  TRANSFER TAXES.
 
    The Issuers will pay all transfer taxes, if any, applicable to the transfer
of Senior Discount Debentures to it or its order pursuant to the Exchange Offer.
If, however, Exchange Debentures and/or substitute Senior Discount Debentures
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 Senior Discount
Debentures tendered hereby, or if tendered Senior Discount Debentures are
registered in the name of any person other than the person signing this Letter,
or if a transfer tax is imposed for any reason other than the transfer of Senior
Discount Debentures to the Issuers 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 SENIOR DISCOUNT DEBENTURES SPECIFIED IN
THIS LETTER.

7.  WAIVER OF CONDITIONS.
 
    The Issuers reserve the absolute right to waive satisfaction of any or all
conditions enumerated in the Prospectus.
 
8.  NO CONDITIONAL TENDERS.
 
    No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Senior Discount Debentures, by execution of
this Letter, shall waive any right to receive notice of the acceptance of their
Senior Discount Debentures for exchange.
 
    Neither the Issuers, the Exchange Agent nor any other person is obligated to
give notice of any defect or irregularity with respect to any tender of Senior
Discount Debentures nor shall any of them incur any liability for failure to
give any such notice.
 
9.  MUTILATED, LOST, STOLEN OR DESTROYED SENIOR DISCOUNT DEBENTURES.
 
    Any holder whose Senior Discount Debentures 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, may be directed to the
Exchange Agent, at the address and telephone number indicated above.
 
11. INCORPORATION OF LETTER OF TRANSMITTAL.

accepted by any tender through the Book-Entry Transfer Facility's ATOP

any Senior Discount Debentures so tendered.
