RECEIPT OF NOTICE FROM THE COMPANY OF THE OCCURRENCE OF ANY EVENT OR THE
DISCOVERY OF ANY FACT WHICH MAKES ANY STATEMENT CONTAINED OR INCORPORATED BY
REFERENCE IN THE PROSPECTUS UNTRUE IN ANY MATERIAL RESPECT OR WHICH CAUSES THE
PROSPECTUS TO OMIT TO STATE A MATERIAL FACT NECESSARY IN ORDER TO MAKE THE
STATEMENTS CONTAINED OR INCORPORATED BY REFERENCE THEREIN, IN LIGHT OF THE
CIRCUMSTANCES UNDER WHICH THEY WERE MADE, NOT MISLEADING OR OF THE OCCURRENCE OF
CERTAIN OTHER EVENTS SPECIFIED IN THE REGISTRATION RIGHTS AGREEMENT, SUCH
PARTICIPATING BROKER-DEALER WILL SUSPEND THE SALE OF EXCHANGE NOTES PURSUANT TO
THE PROSPECTUS UNTIL THE COMPANY HAS AMENDED OR SUPPLEMENTED THE PROSPECTUS TO
CORRECT SUCH

                                       5
<Page>
MISSTATEMENT OR OMISSION AND HAS FURNISHED COPIES OF THE AMENDED OR SUPPLEMENTED
PROSPECTUS TO THE PARTICIPATING BROKER-DEALER OR THE COMPANY HAS GIVEN NOTICE
THAT THE SALE OF THE EXCHANGE NOTES MAY BE RESUMED, AS THE CASE MAY BE. IF THE

EXTEND THE ONE-YEAR PERIOD REFERRED TO ABOVE DURING WHICH PARTICIPATING
BROKER-DEALERS ARE ENTITLED TO USE THE PROSPECTUS IN CONNECTION WITH THE RESALE
OF EXCHANGE NOTES BY THE NUMBER OF DAYS DURING THE PERIOD FROM AND INCLUDING THE
DATE OF THE GIVING OF SUCH NOTICE TO AND INCLUDING THE DATE WHEN PARTICIPATING
BROKER-DEALERS SHALL HAVE RECEIVED COPIES OF THE SUPPLEMENTED OR AMENDED
PROSPECTUS NECESSARY TO PERMIT RESALES OF THE EXCHANGE NOTES OR TO AND INCLUDING
THE DATE ON WHICH THE COMPANY HAS GIVEN NOTICE THAT THE SALE OF EXCHANGE NOTES

accepted for exchange will cease to accrue upon issuance of the Exchange Notes.
Interest on the Exchange Notes is payable semi-annually on each June 15 and
December 15 of each year.

    All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall survive the death or incapacity of the undersigned and any
obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, personal representatives, trustees in bankruptcy,
legal representatives, successors and assigns of the undersigned.

reliance on the position of the Staff enunciated in Exxon Capital Holdings Corp.

June 5, 1991). The Company has not entered into any arrangement or understanding
with any person to distribute the Exchange Notes to be received in the Exchange
Offer and, to the best of its information and belief, each person participating
in the Exchange Offer is acquiring the Exchange Notes in its ordinary course of
business and has no arrangement or understanding with any person to participate
in the distribution of the Exchange Notes to be received in the Exchange Offer.
In this regard, the undersigned is aware that if the undersigned is
participating in the Exchange Offer for the purpose of distributing the Exchange

prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction. The undersigned is aware that such a secondary
resale transaction by a person participating in the Exchange Offer for the
purpose of distributing the Exchange Notes should be covered by an effective
registration statement containing the selling securityholder information
required by Item 507 of Regulation S-K.

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

    (i) this Consent and 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 the relevant security position
       listing as the owner of the Outstanding Notes) of Outstanding Notes
       tendered herewith, unless such holder(s) has completed either the box
       entitled "Special Issuance Instructions" or the box entitled "Special
       Delivery Instructions" above, or

    (ii) such Outstanding 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(s)
on this Letter of Transmittal. See Instruction 5.

    3.  INADEQUATE SPACE.  If the space provided in the box captioned
"Description of Outstanding Notes" is inadequate, the Certificate number(s)
and/or the aggregate principal amount of Outstanding 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.  If less than all the Outstanding
Notes evidenced by any Certificate submitted are to be tendered, fill in the
aggregate principal amount of Outstanding Notes which are to be tendered in the
box entitled "Aggregate Principal Amount of Outstanding Notes Tendered for
Exchange." In such case, new Certificates for the remainder of the Outstanding
Notes that were evidenced by old Certificates will be sent to the holder of the
Outstanding Notes (or such other party as you identify in the box captioned
"Special Delivery Instructions"), promptly after the Expiration Date. All
Outstanding Notes represented by Certificates delivered to the Exchange Agent or
transferred to the Exchange Agent by means of a book-entry transfer will be
deemed to have been tendered unless otherwise indicated.

    Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time on or prior to the Expiration Date. In order for a
withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission of such notice of withdrawal must be timely received by the
Exchange Agent at its address set forth above on or prior to the Expiration
Date. Any such notice of withdrawal must specify the name of the person who
tendered the Outstanding Notes to be withdrawn, the aggregate principal amount
of Outstanding Notes to be withdrawn, and (if Certificates for Outstanding Notes
have been tendered) the name of the registered holder of the Outstanding Notes
as set forth on the Certificate for the Outstanding Notes, if different from
that of the person who tendered such Outstanding Notes. If Certificates for the
Outstanding Notes have been delivered or otherwise identified to the Exchange
Agent, then prior to the physical release of such Certificates for the
Outstanding Notes, the tendering holder must submit the serial numbers shown on
the particular Certificates for the Outstanding Notes to be withdrawn and the
signature on the notice of withdrawal must be guaranteed by an Eligible
Institution, except in the case of Outstanding Notes tendered for the account of
an Eligible Institution. If Outstanding Notes have been tendered pursuant to the
procedures for book-entry transfer set forth in "The Exchange Offer--Procedures
for Tendering Outstanding Notes," the notice of withdrawal must specify the name
and number of the account at DTC to be credited with the withdrawal of
Outstanding Notes, in which case a notice of withdrawal will be effective if
delivered to the Exchange Agent by written or facsimile transmission.
Withdrawals of tenders of Outstanding Notes may not be rescinded. Outstanding
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--Procedures for Tendering Outstanding Notes."

    All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
The Company, any affiliates or assigns of the Company, the Exchange Agent

                                       10
<Page>
or 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 Outstanding Notes which have been tendered but
which are withdrawn will be returned to the holder thereof promptly after
withdrawal.

of book-entry securities, on the relevant security position listing) without
alteration, enlargement or any change whatsoever.

    If any of the Outstanding 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 Outstanding Notes are registered in different name(s) 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

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 Company, in its sole discretion, of such persons' authority
to so act.

    When this Letter of Transmittal is signed by the registered owner(s) of the
Outstanding Notes listed and transmitted hereby, no endorsement(s) of
Certificate(s) or separate bond power(s) are required unless Exchange Notes are
to be issued in the name of a person other than the registered holder(s).
Signature(s) on such Certificate(s) or bond power(s) must be guaranteed by an
Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Outstanding Notes listed, the Certificates must be
endorsed or accompanied by appropriate bond powers, signed exactly as the name
or names of the registered owner(s) appear(s) on the Certificates, and also must
be accompanied by such opinions of counsel, certifications and other information
as the Company may require in accordance with the restrictions on transfer
applicable to the Outstanding Notes. Signatures on such Certificates or bond
powers must be guaranteed by an Eligible Institution.

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

    7.  IRREGULARITIES.  The Company will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time of
receipt) and acceptance for exchange of any tender of Outstanding Notes, which
determination shall be final and binding on all parties. The Company reserves
the absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance of which, or exchange for, may, in the view of
counsel to the Company, be unlawful. The Company also reserves 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 Outstanding
Notes of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders. The Company's
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 Outstanding Notes will be deemed to have been validly made until all
irregularities with respect to such tender have been

                                       11
<Page>
cured or waived. The Company, any affiliates or assigns of the Company, 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, REQUEST 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 the

    9.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any Certificate(s)
representing Outstanding 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 Certificate(s). This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen Certificate(s) have been
followed.

    10.  SECURITY TRANSFER TAXES.  Holders who tender their Outstanding 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
Outstanding Notes tendered, or if a transfer tax is imposed for any reason other
than the exchange of Outstanding 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) AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION

    Under federal income tax law, a holder whose tendered Outstanding Notes are
accepted for exchange is required by law to provide the Exchange Agent with such
holder's correct taxpayer identification number ("TIN") on Substitute Form W-9
included herein or otherwise establish a basis for exemption from backup
withholding. If such holder is an individual, the TIN is his or her social
security number. If the Exchange Agent is not provided with the correct TIN, the
Internal Revenue Service may subject the holder or transferee to a $50.00
penalty. In addition, delivery of such holder's Exchange Notes may be subject to
backup withholding. Failure to comply truthfully with the backup withholding
requirements also may result in the imposition of severe criminal and/or civil
fines and penalties.

    Certain holders (including, among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements. Exempt holders should furnish their TIN, write "Exempt" on the
face of the Substitute Form W-9, and sign, date and return the Substitute
Form W-9 to the Exchange Agent. A foreign person, including entities, may
qualify as an exempt recipient by submitting to the Exchange Agent a properly
completed Internal Revenue Service Form W-8, signed under penalties of perjury,
attesting to that holder's foreign status. A Form W-8 can be obtained from the
Exchange Agent. See "Guidelines for Certification of Taxpayer Identification
Number on Substitute Form W-9" for additional instruction.

    If backup withholding applies, the Exchange Agent is required to withhold
28% of any payments made to the holder or other transferee. Backup withholding
is not an additional federal income tax. Rather, the federal income 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.

PURPOSE OF SUBSTITUTE FORM W-9

    To prevent backup withholding on payments made with respect to Outstanding
Notes exchanged in the Exchange Offer, the holder is required to provide the
Exchange Agent with either: (i) the holder's correct TIN by completing the form
included herein, certifying that the TIN provided on Substitute Form W-9 is
correct (or that such holder is awaiting a TIN) and that (A) the holder has not
been notified by the Internal Revenue Service that the holder is subject to
backup withholding as a result of failure to report all interest or dividends or
(B) the Internal Revenue Service has notified the holder that the holder is no
longer subject to back withholding; or (ii) an adequate basis for exemption.

NUMBER TO GIVE THE DEPOSITORY

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