Ladies and Gentlemen:
 
     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned tenders to the Company the number of Original Preferred Shares
indicated above. Subject to, and effective upon, the acceptance for exchange of
the Original Preferred Shares tendered with this Letter, the undersigned
exchanges, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to the Original Preferred Shares tendered.
 
     The undersigned constitutes and appoints the Exchange Agent as his or her
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
Preferred Shares, with full power of substitution, to (a) deliver certificates
for such Original Preferred Shares; (b) deliver Original Preferred Shares and
all accompanying evidence of transfer and authenticity to or upon the order of
the Company upon receipt by the Exchange Agent, as the undersigned's agent, of
the New Preferred Shares to which the undersigned is entitled upon the
acceptance by the Company of the Original Preferred Shares tendered under the
Exchange Offer; and (c) receive all benefits and otherwise exercise all rights
of beneficial ownership of the Original Preferred Shares, all in accordance with
the terms of the Exchange Offer. The power of attorney granted in this paragraph
shall be deemed irrevocable and coupled with an interest.
 
     The undersigned hereby represents and warrants that he or she has full
power and authority to tender, exchange, assign and transfer the Original
Preferred Shares 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. The undersigned will,
upon request, execute and deliver any additional documents deemed by the Company
to be necessary or desirable to complete the assignment and transfer of the
Original Preferred Shares tendered.
 
     The undersigned agrees that acceptance of any tendered Original Preferred
Shares by the Company and the issuance of New Preferred Shares in exchange
therefor shall constitute performance in full by the
 
                                        2
   3
 
   
Company of its obligations under the Registration Agreement (as defined in the
Prospectus) and that, upon the issuance of the New Preferred Shares, the Company
will have no further obligations or liabilities thereunder (except in certain
limited circumstances). By tendering Original Preferred Shares, the undersigned
certifies (a) that it is not an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act, that it is not a broker-dealer that owns
Original Preferred Shares acquired directly from the Company or an affiliate of
the Company, that it is acquiring the New Preferred Shares in the ordinary
course of the undersigned's business and that the undersigned is not engaged in,
and does not intend to engage in, a distribution of New Preferred Shares or (b)
that it is an "affiliate" (as so defined) of the Company or of the initial
purchasers in the offering of the Original Preferred Shares, and that it will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable to it. If required, the Company will
amend the registration statement relating to the Exchange Offer to include the
selling stockholder information required by Item 507 of Regulation S-K.
    
 
     The undersigned acknowledges that, if it is a broker-dealer that will
receive New Preferred Shares for its own account in exchange for Original
Preferred Shares that were acquired as a result of market-making activities or
other trading activities, it will deliver a prospectus in connection with any
resale of such New Preferred Shares. By so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
     The undersigned understands that the Company may accept the undersigned's
tender by delivering written notice of acceptance to the Exchange Agent, at
which time the undersigned's right to withdraw such tender will terminate.
 
     All authority conferred or agreed to be conferred by this Letter shall
survive the death or incapacity of the undersigned, and every obligation of the
undersigned under this Letter shall be binding upon the undersigned's heirs,
personal representatives, successors and assigns. Tenders may be withdrawn only
in accordance with the procedures set forth in the Instructions contained in
this Letter.
 
     Unless otherwise indicated under "Special Delivery Instructions" below, the
Exchange Agent will deliver New Preferred Shares (and, if applicable, a
certificate for any Original Preferred Shares not tendered but represented by a
certificate also encompassing Original Preferred Shares which are tendered) to
the undersigned at the address set forth in Box 1.
 
     The undersigned acknowledges that the Exchange Offer is subject to the more
detailed terms set forth in the Prospectus and, in case of any conflict between
the terms of the Prospectus and this Letter, the Prospectus shall prevail.

defined in the Prospectus under the caption "The Exchange Offer"); (ii) prior to
the Expiration Date, the Exchange Agent must have received from the Eligible
Institution a properly completed and duly executed Notice of Guaranteed Delivery
(by telegram, telex, facsimile transmission, mail or hand delivery) (x) setting
forth the name and address of the holder, the description of the Original
Preferred Shares and number of Original Preferred Shares tendered, (y) stating
that the tender is being made thereby and (z) guaranteeing that, within three
New York Stock Exchange trading days after the date of execution of such Notice
of Guaranteed Delivery, this Letter together with the certificates representing
the Original Preferred Shares or a Book-Entry Confirmation, as the case may be,
and any other documents required by this Letter will be deposited by the
Eligible Institution with the Exchange Agent; and (iii) the certificates for all
tendered Original Preferred Shares or a Book-Entry Confirmation, as the case may
be, as well as all other documents required by this Letter, must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
date of execution of such Notice of Guaranteed Delivery, all as provided in the
Prospectus under the caption "The Exchange Offer -- How to Tender."
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Preferred Shares will
be determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders that are not in
proper form or the acceptance of which, in the opinion of the Company's counsel,
would be unlawful. The Company also reserves the right to waive any
irregularities or conditions of tender as to particular Original Preferred
Shares. All tendering holders, by execution of this Letter, waive any right to
receive notice of acceptance of their Original Preferred Shares.
 
     Neither the Company, the Exchange Agent nor any other person shall be
obligated to give notice of defects or irregularities in any tender, nor shall
any of them incur any liability for failure to give any such notice.
 
     2.  PARTIAL TENDERS; WITHDRAWALS.  If fewer than all of the Original
Preferred Shares evidenced by a submitted certificate or by a Book-Entry
Confirmation are tendered, the tendering holder must fill in the number tendered
in the fourth column of Box 1 above. All of the Original Preferred Shares
represented by a certificate or by a Book-Entry Confirmation delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
A certificate for Original Preferred Shares not tendered will be sent to the
holder, unless otherwise provided in Box 5, as soon as practicable after the
Expiration Date, in the event that fewer than all of the Original Preferred
Shares represented by a submitted certificate are tendered (or, in the case of
Original Preferred Shares tendered by book-entry transfer, such non-exchanged
Original Preferred Shares will be credited to an account maintained by the
holder with the Book-Entry Transfer Facility).
 
     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 Original Preferred Shares, a notice of withdrawal must (i) be received
by the Exchange Agent before the Company notifies the Exchange Agent that it has
accepted the tender of Original Preferred Shares pursuant to the Exchange Offer;
(ii) specify the name of the person who tendered the Original Preferred Shares;
(iii) contain a description of the Original Preferred Shares to be withdrawn,
the certificate numbers shown on the particular certificates evidencing such
Original Preferred Shares and the number of Original Preferred Shares
represented
                                        8
   9
 
by such certificates; and (iv) be signed by the holder in the same manner as the
original signature on this Letter (including any required signature guarantee).
 
     3.  SIGNATURES ON THIS LETTER; ASSIGNMENTS; GUARANTEE OF SIGNATURES.  If
this Letter is signed by the holder(s) of Original Preferred Shares tendered
hereby, the signature must correspond with the name(s) as written on the face of
the certificate(s) for such Original Preferred Shares, without alteration,
enlargement or any change whatsoever.
 
     If any of the Original Preferred Shares tendered hereby are owned by two or
more joint owners, all owners must sign this Letter. If any tendered Original
Preferred Shares are held 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 names in which certificates are held.
 
     If this Letter is signed by the holder of record and (i) all of the
holder's Original Preferred Shares are tendered; and/or (ii) untendered Original
Preferred Shares, if any, are to be issued to the holder of record, then the
holder of record need not endorse any certificates for tendered Original
Preferred Shares, nor provide a separate bond power. If any other case, the
holder of record must transmit a separate bond power with this Letter.
 
     If this Letter or any certificate or assignment is 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 proper evidence satisfactory to the
Company of their authority to so act must be submitted, unless waived by the
Company.
 
     Signatures on this Letter must be guaranteed by an Eligible Institution,
unless Original Preferred Shares are tendered (i) by a holder 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. In the event that the signatures in this Letter or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by an eligible guarantor institution which is a member of The Securities
Transfer Agents Medallion Program (STAMP), The New York Stock Exchanges
Medallion Signature Program (MSP) or The Stock Exchanges Medallion Program
(SEMP) (collectively, "Eligible Institutions"). If Original Preferred Shares are
registered in the name of a person other than the signer of this Letter, the
Original Preferred Shares 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 Institution.
 
     4.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders should
indicate, in Box 4 or 5, as applicable, the name and address to which the New
Preferred Shares or certificates for Original Preferred Shares not exchanged are
to be issued or sent, if different from the name and address of the person
signing this Letter. In the case of issuance in a different name, the tax
identification number of the person named must also be indicated. Holders
tendering Original Preferred Shares by book-entry transfer may request that
Original Preferred Shares not exchanged be credited to such account maintained
at the Book-Entry Transfer Facility as such holder may designate.
 
     5.  TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder whose tendered Original Preferred Shares are accepted for exchange must
provide the Exchange Agent (as payor) with his or her correct and properly
certified taxpayer identification number ("TIN"), which, in the case of a holder
who is an individual, is his or her social security number. If the Exchange
Agent is not provided with the correct TIN, the holder may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, delivery to the
holder of the New Preferred Shares pursuant to the Exchange Offer may be subject
to back-up withholding. (If withholding results in overpayment of taxes, a
refund or credit may be obtained.) Exempt holders (including, among others,
substantially all corporations and nonresident aliens) are not subject to these
back-up withholding and reporting requirements. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
     Under federal income tax laws, payments that may be made by the Company on
account of New Preferred Shares issued pursuant to the Exchange Offer may be
subject to back-up withholding at a rate of 31%. In order to avoid being subject
to back-up withholding, each tendering holder must provide his or her correct
TIN by completing the "Substitute Form W-9" referred to above, certifying that
the TIN provided is the holder's correct TIN(or that the holder is awaiting a
TIN) and that (i) the holder has not been notified by the Internal Revenue
Service that he or she is subject to back-up withholding as a result of failure
to report all interest or dividends; or (ii) the Internal Revenue Service has
notified the holder that he or she is no longer subject to back-up withholding;
or (iii) such holder is exempt from back-up

                                        9
   10
 
withholding. If the Original Preferred Shares are in more than one name or are
not in the name of the actual owner, consult the enclosed Guidelines for
information on which TIN to report.
 
     6.  TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the transfer of Original Preferred Shares to it or its order
pursuant to the Exchange Offer. If, however, the New Preferred Shares or
certificates for Original Preferred Shares not exchanged are to be delivered to,
or are to be issued in the name of, any person other than the record holder, or
if tendered certificates are recorded in the name of any person other than the
person signing this Letter, or if a transfer tax is imposed by any reason other
than the transfer of Original Preferred Shares to the Company or its order
pursuant to the Exchange Offer, then the amount of such transfer taxes (whether
imposed on the record holder or any other person) will be payable by the
tendering holder. If satisfactory evidence of payment of taxes or exemption from
taxes is not submitted with this Letter, the amount of transfer taxes will be
billed directly to the tendering holder.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter.
 
     7.  WAIVER OF CONDITIONS.  The Company reserves the absolute right to amend
or waive any of the specified conditions in the Exchange Offer in the case of
any Original Preferred Shares tendered.
 
     8.  MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES.  Any holder whose
certificates for Original Preferred Shares have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating to
the procedure for tendering, as well as requests for additional copies of the
Prospectus or this Letter, may be directed to the Exchange Agent.
 
     IMPORTANT:  This Letter (together with certificates representing tendered
Original Preferred Shares or a Book-Entry Confirmation and all other required
documents) must be received by the Exchange Agent on or before the Expiration
Date (as defined in the Prospectus).

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9
 
GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE
PAYER.--Social Security numbers have nine digits separated by two hyphens: i.e.
000-00-000. Employer identification numbers have nine digits separated by only
one hyphen: i.e. 00-0000000. If you are a resident alien and you do not have and
are not eligible to get a social security number, you should obtain from the IRS
an "individual taxpayer identification number" (ITIN) and provide that ITIN. The
table below will help determine the number to give the payer.

returns. Payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payer. Certain penalties may also apply.
 
PENALTIES

to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless you failure is due to reasonable
cause and not to willful neglect.
(2) CIVIL PENALTY FOR FAILURE INFORMATION WITH RESPECT TO WITHHOLDING--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

SERVICE.
