                                    ITEM B.

                (MUST BE COMPLETED BY ALL HOLDERS OF DEBENTURES)

     THE ABOVE DEBENTURES ARE SURRENDERED FOR THE ACTION INDICATED BELOW.



[ ]  CONVERSION  into   shares  of  common  stock,  par  value  $.001  per share
     ("Common  Stock"),  of the Company  ("Shares") at the  conversion  price of
     $32.125 per Share  (equivalent to 31.13 Shares per $1,000  principal amount
     of  Debentures),  with cash in lieu of fractional  Shares.  Such payment of
     cash will be in the form of a check  drawn on an  account of the Paying and
     Conversion Agent. See Instruction 2. Complete Items C and E below.

     Holders of Debentures who convert their  Debentures will not be entitled to
     any accrued but unpaid interest on the Debentures.

     SO LONG AS THE MARKET  PRICE OF THE COMMON STOCK IS GREATER THAN $34.05 PER
     SHARE AT THE TIME OF  CONVERSION,  A HOLDER WHO  CONVERTS  DEBENTURES  INTO
     COMMON STOCK WILL RECEIVE CONSIDERATION (COMMON STOCK, PLUS CASH IN LIEU OF
     ANY  FRACTIONAL  SHARE) HAVING A MARKET VALUE  GREATER THAN THE  REDEMPTION
     PRICE OF THE  DEBENTURES.  TAXES,  COMMISSIONS  AND OTHER COSTS WHICH WOULD
     LIKELY BE INCURRED UPON SALE OF COMMON STOCK  RECEIVED  UPON  CONVERSION OF
     THE  DEBENTURES  WOULD  REDUCE  OR  ELIMINATE  THE  ECONOMIC  ADVANTAGE  OF
     CONVERSION OVER REDEMPTION.  MOREOVER, THE MARKET VALUE OF THE COMMON STOCK
     RECEIVED IS SUBJECT TO FLUCTUATION. SEE INSTRUCTION 2 BELOW FOR INFORMATION
     RELATING TO THE PAYMENT OF CASH IN LIEU OF ANY FRACTIONAL SHARE.

[ ]  REDEMPTION  at a price of  103.0% of the  principal  amount  thereof,  plus
     interest  accruing from January 1, 1998 to the Redemption  Date of June 29,
     1998 (the  "Redemption  Price").  A holder of  $1,000  principal  amount of
     Debentures  redeemed at the  Redemption  Price would  receive  $1,059.83 in
     cash.

     See Instruction 3. Complete Items D and E below.

[ ]  PARTIAL  CONVERSION/PARTIAL  REDEMPTION.  If this box is  checked  you must
     indicate (1) the principal  amount of  Debentures  you wish to convert into
     Shares on Item C and (2) the  principal  amount of  Debentures  you wish to
     have  redeemed  on  Item  D.  If  this  box is  checked  and no  additional
     instructions  are provided,  the delivery of Debentures prior to 5:00 p.m.,
     New York City  time,  on June 29,  1998,  will be treated by the Paying and
     Conversion  Agent as an instruction to convert such Debentures into Shares.
     Complete Items C, D and E below.

[ ]  CHECK  HERE IF  DEBENTURES  ARE  BEING  DELIVERED  PURSUANT  TO A NOTICE OF
     GUARANTEED DELIVERY PREVIOUSLY SENT TO THE PAYING AND CONVERSION AGENT.

THE  FOREGOING  ELECTIONS  ARE  IRREVOCABLE.  IF NO BOX IS CHECKED AND THE ABOVE
DEBENTURES ARE RECEIVED BY THE PAYING AND  CONVERSION  AGENT PRIOR TO 5:00 P.M.,
NEW YORK CITY TIME, ON JUNE 29, 1998, SUCH DEBENTURES WILL BE DEEMED SURRENDERED
FOR CONVERSION INTO SHARES. IF ANY DEBENTURES ARE RECEIVED AFTER THAT TIME, TIME
BEING OF THE ESSENCE,  SUCH DEBENTURES  WILL BE REDEEMED  REGARDLESS OF WHICH OR
WHETHER ANY CHOICE IS INDICATED.

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL

     1. GENERAL.  Please do not send Debentures to the Company.  The Debentures,
together with the signed and completed  Letter of  Transmittal  and any required
supporting  documents (see Instruction 2 below),  should be mailed, or otherwise
delivered,  to The Bank of New York,  as Paying  and  Conversion  Agent,  at its
appropriate address indicated on the first page of the Letter of Transmittal. If
mail is used,  it is  recommended  that  registered  mail,  with return  receipt
requested, properly insured, be used as a precaution against loss. Consideration
should  be  given  to  using  some  form of  express  delivery  service,  as the
conversion alternative discussed below expires at 5:00 p.m., New York City time,
on June 29, 1998,  time being of the  essence.  The method of  transmitting  the
Debentures,  however,  is at your sole  option and risk.  If you wish to convert
your Debentures,  your Debentures and a properly completed Letter of Transmittal
must be  RECEIVED  by the Paying and  Conversion  Agent at one of the  addresses
listed on the front page  hereof by 5:00 p.m.,  New York City time,  on June 29,
1998. 

              ALL ELECTIONS TO CONVERT OR REDEEM ARE IRREVOCABLE.

               ITEMS A, B, E AND F OF THIS LETTER OF TRANSMITTAL
                         MUST BE COMPLETED IN ALL CASES.

     2. IF YOU WISH TO CONVERT  YOUR  DEBENTURES.  If you wish to  convert  your
Debentures  into Shares of Common Stock,  then prior to 5:00 p.m., New York City
time, on June 29, 1998 you must deposit with the Paying and Conversion Agent (a)
the Debentures, (b) a properly completed Letter of Transmittal and (c) any other
documents required by this Letter of Transmittal. If your Debenture Certificates
are not immediately available, please see Instruction 7.

     Debentures  surrendered  for  conversion  will not be  entitled to interest
accrued to the date of conversion.  Instead of issuing any  fractional  Share of
Common Stock which would  otherwise be issuable upon conversion of any Debenture
(or  specified  portions  thereof),  the Company will pay a cash  adjustment  in
respect of such  fraction in an amount equal to the same fraction of the Closing
Price (as defined below) at the close of business on the day of conversion  (or,
if such  day is not a  Trading  Day  (as  defined  below),  on the  Trading  Day
immediately  preceding such day).  "Closing Price" means the last reported sales
price regular way or, in case no such reported sale takes place on such day, the
average of the reported closing bid and asked prices regular way, in either case
on the New York Stock  Exchange  ("NYSE").  "Trading  Day"  means  each  Monday,
Tuesday, Wednesday,  Thursday and Friday, other than any day on which securities
are generally not traded on the NYSE.  The  Debentures  will not be  convertible
after 5:00 P.M., New York City time, on the Redemption  Date.  Such cash in lieu
of any fractional  Share will be paid by check drawn on an account of the Paying
and Conversion Agent.

     Each holder of Debentures that does not directly hold  certificates for its
Debentures,  but instead maintains its holdings  indirectly in an account with a
broker or other intermediary (each, a "Beneficial  Holder") must comply with the
procedures of such intermediary to convert such Beneficial Holder's  Debentures.
Such an intermediary may maintain its holdings with The Depository Trust Company
("DTC").  In those instances,  the procedures of DTC must also be followed for a
Beneficial Holder to convert its Debentures.

     IT IS THE  RESPONSIBILITY OF EACH BENEFICIAL HOLDER TO GIVE INSTRUCTIONS TO
ITS  INTERMEDIARY  IN  SUFFICIENT  TIME  FOR  THAT   INTERMEDIARY,   ANY  HIGHER
INTERMEDIARIES  AND THE RECORD  HOLDER OF SUCH  BENEFICIAL  HOLDER'S  DEBENTURES
(WHICH MAY BE DTC) TO TAKE THE ACTIONS WHICH ARE NECESSARY TO EFFECT  CONVERSION
OF SUCH BENEFICIAL  HOLDER'S  DEBENTURES PRIOR TO 5:00 P.M., NEW YORK CITY TIME,
ON THE REDEMPTION DATE.

     AS LONG AS THE MARKET PRICE OF THE COMMON STOCK  REMAINS AT OR ABOVE $34.05
PER SHARE,  THE HOLDERS OF DEBENTURES  WHO ELECT TO CONVERT WILL  RECEIVE,  UPON
CONVERSION, COMMON STOCK (INCLUDING CASH, IF ANY, RECEIVED IN LIEU OF FRACTIONAL
SHARES)  HAVING A GREATER MARKET VALUE THAN THE AMOUNT OF CASH  RECEIVABLE  UPON
REDEMPTION OF SUCH DEBENTURES (BEFORE DEDUCTING ANY TAXES, COMMISSIONS AND OTHER
COSTS WHICH WOULD LIKELY BE INCURRED ON SALE OF THE COMMON STOCK  RECEIVED  UPON
CONVERSION OF 

                                       7


THE DEBENTURES). IT SHOULD BE NOTED, HOWEVER, THAT THE PRICE OF THE COMMON STOCK
RECEIVED UPON CONVERSION WILL FLUCTUATE IN THE MARKET. NO ASSURANCE CAN BE GIVEN
AS TO THE PRICE OF THE COMMON STOCK AT ANY FUTURE TIME,  AND THE HOLDERS  SHOULD
EXPECT TO INCUR VARIOUS EXPENSES OF SALE IF SUCH COMMON STOCK IS SOLD.

     If the stock  certificates and any cash in lieu of fractional Shares are to
be (i) issued in the same  name(s) as that in which the  surrendered  Debentures
are  registered and (ii) mailed to the same address as given in Item A, complete
Items A, B, E and F.

     If the stock  certificates and any cash in lieu of fractional Shares are to
be issued in the name or names of a different  person(s),  see Instructions 4, 5
and 6 and complete Items A, B, C, E and F.

     If the stock  certificates and any cash in lieu of fractional Shares are to
be mailed to an address  different  from that given in Item A, complete Items A,
B, C, E and F.

     If more than one Debenture is  surrendered  for  conversion at any one time
under the same Letter of  Transmittal  or other notice by the same  holder,  the
number of Shares  issuable upon  conversion of such  Debentures will be computed
upon the basis of the aggregate  principal  amount of Debentures so surrendered.
Holders  are also  entitled  to  convert  fewer than all  Debentures  they hold,
provided  that  any  conversions  are for  amounts  of  Debentures  in  integral
multiples of $1,000.

     A single  Common Stock  certificate  will be issued unless you give written
instructions to the contrary.  The Common Stock  certificate and cash in lieu of
fractional  Shares  will be mailed as soon as  possible  after  receipt  of your
Debentures.

     3. IF YOU WISH TO REDEEM YOUR DEBENTURES. If you wish your Debentures to be
redeemed by the Company, deliver your Debentures and a properly completed Letter
of  Transmittal  to the Paying and  Conversion  Agent. A check for $1,059.83 per
$1,000  principal  amount of Debentures  will be sent to you when the Debentures
have been received by the Paying and Conversion  Agent,  but in no event earlier
than the Redemption Date, June 29, 1998.

     NOTE: THE PRICE  RECEIVABLE  UPON  REDEMPTION OF THE DEBENTURES MAY BE LESS
THAN THE CURRENT  MARKET  VALUE OF THE COMMON  STOCK  (INCLUDING  CASH,  IF ANY,
RECEIVED IN LIEU OF A FRACTIONAL SHARE) RECEIVABLE UPON CONVERSION.

     If the  check is to be  issued  in the same  name(s)  as that in which  the
surrendered Debentures are registered and mailed to the same address as given in
Item A, complete Items A, B, E and F.

     If the check is to be issued in a different name or names, see Instructions
4 and 5 and complete Items A, B, D, E and F.

     If the check is to be mailed to an  address  different  from that  given in
Item A, complete Items A, B, D, E and F.

     4.  CERTIFICATE  OR  CHECK  TO  BE  ISSUED  IN  A  DIFFERENT  NAME.  Unless
instructions  are given in Item C or D, the Shares  and/or check (if any) are to
be  issued  in the  same  name as that of the  record  holder  inscribed  on the
surrendered Debenture. If the Shares and/or check (if any) are to be issued in a
name  other than that of the record  holder of the listed  Debenture,  please be
guided by the following:

       (a)  Endorsement  and  Guarantee.  The  Debentures  surrendered  must  be
    properly endorsed (or accompanied by one or more appropriate powers properly
    executed  by the record  holder of such  Debentures  to the person who is to
    receive the Common Stock certificate(s)  and/or check). The signature of the
    record holder on the  endorsement or power must  correspond with the name as
    written upon the face of the Debentures  surrendered in every particular and
    must be guaranteed by a commercial bank or trust company having an office or
    correspondent in the United States,  a member firm of a national  securities
    exchange or the  National  Association  of  Securities  Dealers,  Inc. or an
    "eligible  guarantor   institution"  within  the  meaning  of  Rule  17Ad-15
    promulgated under the Securities  Exchange Act of 1934, as amended (each, an
    "Eligible Institution").

                                       8


       (b) Transferee's  Signature.  The Letter of Transmittal must be signed by
    the person to whom  transfer or  assignment is made, or by his or her agent,
    and  should  not be signed  by the  person  transferring  or  assigning  the
    Debentures.  The  signature  of such  transferee,  assignee or agent must be
    guaranteed as provided in Instruction 4(a).

       (c)  Correction  of or Change  in Name.  For a name  correction  or for a
    change in name that does not  involve  a change  of  ownership,  proceed  as
    follows: For a correction in name, the listed Debentures should be endorsed,
    for example,  "James E. Brown,  incorrectly  inscribed as J. E. Brown," with
    the signature  guaranteed as described in Instruction  4(a). For a change in
    name by  marriage,  the  surrendered  Debentures  should  be  endorsed,  for
    example,  "Mary Doe, now by marriage,  Mrs.  Mary Jones," with the signature
    guaranteed as described in Instruction 4(a).

     5. SIGNATURE BY FIDUCIARY OR OTHER THAN REGISTERED  HOLDER.  If this Letter
of  Transmittal  is  signed  by  the  registered  holder(s)  of  the  Debentures
transmitted herewith, the signatures must correspond exactly with the name(s) of
such registered holder(s).

     If  the  Letter  of  Transmittal  is  signed  in  Item  E by  an  executor,
administrator,  trustee,  guardian,  attorney or the like, such person should so
indicate when signing,  and the Letter of  Transmittal  and  Debentures  must be
accompanied by evidence, satisfactory to the Paying and Conversion Agent and the
Company, of the authority of such person to sign the Letter of Transmittal,  and
the signature must be properly guaranteed by an Eligible Institution.

     If the Letter of  Transmittal  is signed in Item E by a person,  other than
the registered holder, who is not a person described in the preceding paragraph,
the  surrendered  Debentures  must be  properly  endorsed or be  accompanied  by
appropriate powers,  properly executed by the registered owner(s),  so that such
endorsement  or powers are  signed  exactly  as the  name(s)  of the  registered
owner(s)  appear(s)  on the  Debentures  and the  signature(s)  must be properly
guaranteed by an Eligible Institution.

     If the Debentures are endorsed by, or accompanied by bond powers signed by,
trustees, executors, administrators,  guardians, attorneys-in-fact,  officers of
corporations or other persons acting in a fiduciary or representative  capacity,
such persons should so indicate when signing,  and proper evidence  satisfactory
to the  Company  of  their  authority  so to act  must  be  submitted,  and  the
signatures must be properly guaranteed by an Eligible Institution.

     If you have completed Item C or D regarding special issuance  instructions,
the signature on this Letter of  Transmittal  must be  guaranteed,  in the space
provided in Item E, by an Eligible Institution.

     6. JOINT HOLDERS OR DEBENTURES REGISTERED IN DIFFERENT NAMES. If Debentures
are  surrendered  by joint  holders or owners,  all such  persons  must sign the
Letter of Transmittal in Item E. If Debentures are registered in different names
or forms of ownership, separate Letters of Transmittal must be completed, signed
and returned for each different registration. See Instruction 5 above.

     7. NOTICE OF  GUARANTEED  DELIVERY.  Debenture  holders  wishing to convert
their Debentures  whose  Debentures are not immediately  available or who cannot
deliver their  Debentures and all other documents  required hereby to the Paying
and  Conversion  Agent on or prior to 5:00 p.m., New York City time, on June 29,
1998 may elect to convert their Debentures pursuant to the following procedures:
(a) such election to convert must be made by or through an Eligible Institution,
(b) a properly completed and duly executed Notice of Guaranteed  Delivery in the
form provided by the Company to all  registered  holders of  Debentures  must be
received by the Paying and  Conversion  Agent on or prior to 5:00 p.m., New York
City time, on June 29, 1998, and (c) the Debentures in proper form for transfer,
together with a properly  completed and duly executed  Letter of Transmittal and
all other documents required by this Letter of Transmittal,  must be received by
the Paying and  Conversion  Agent within three New York Stock  Exchange  trading
days after the date such Notice of Guaranteed Delivery is received by the Paying
and Conversion Agent.  Notwithstanding  the foregoing,  Shares will be issued in
respect of Debentures  surrendered  for conversion  only after timely receipt by
the  Paying  and  Conversion  Agent of the  surrendered  Debentures,  a properly
completed  and duly  executed  Letter of  Transmittal  and any  other  documents
required by the Letter of Transmittal.


                                       9

     8. TRANSFER TAXES.  It is not  anticipated  that any transfer taxes will be
payable in connection with the issuance of certificates  evidencing  Shares upon
conversion of the  Debentures.  If,  however,  it should develop that in certain
circumstances  such  taxes may be  payable,  conversion  of  Debentures  will be
effected  without  charge to the  converting  holder for any such stock transfer
tax, except in the following cases. If stock certificates issued upon conversion
are to be registered in the name of any person other than the  registered  owner
of Debentures,  the amount of any stock  transfer taxes (whether  imposed on the
registered owner(s) of the certificate(s) transmitted herewith or such person(s)
payable on account of the transfer to such person(s)) must accompany this Letter
of Transmittal or evidence must be submitted as to the payment of such taxes, or
exemption therefrom.  The Company will not be required to issue or deliver stock
certificates in any such case until such person(s) has made payment or submitted
such evidence.

     9. LOST OR DESTROYED  DEBENTURES.  If your Debentures have been either lost
or destroyed,  notify The Bank of New York, as Trustee, of this fact immediately
by telephone at (212) 815-3738,  or by mail, hand delivery or overnight  courier
at the  appropriate  address  set  forth  on the  first  page of the  Letter  of
Transmittal.  In order to retain your rights to convert  your  Debentures  which
have been lost or destroyed,  the  procedures  set forth in Item 7(a) and (b) of
these instructions must be followed. You will then be instructed as to the steps
you must take in order to convert or have redeemed the Debentures  that you own.
The Letter of Transmittal  and related  documents  cannot be processed until the
missing  Debentures  have been  replaced.  You must act  promptly if you wish to
safeguard your rights. 

     10. WAIVER OF CONDITIONS.  The Company reserves the absolute right to waive
any of the  conditions  set  forth  herein or any  defect  with  respect  to the
transmittal of the Debentures.

     11. MISCELLANEOUS.  Neither the Company nor the Paying and Conversion Agent
is under any duty to give  notification  of defects in any Letter of Transmittal
or facsimile or in any other required documents, and neither the Company nor the
Paying and  Conversion  Agent shall incur any liability for failure to give such
notification.  Any and all Letters of Transmittal  or facsimiles  (including any
other required documents) not in proper form are subject to rejection.

     12. QUESTIONS ON HOW TO SUBMIT  CERTIFICATES AND OBTAIN ADDITIONAL  COPIES.
All questions  regarding  appropriate  procedures  for  completing the Letter of
Transmittal and  surrendering  Debentures and requests for additional  copies of
the Notice of  Redemption  and Letter of  Transmittal  should be directed to the
Paying and Conversion Agent at (212) 815-3738. 

     13.  SUBSTITUTE FORM W-9. Each Debenture  holder is required to provide the
Paying  and  Conversion  Agent  with a correct  Taxpayer  Identification  Number
("TIN") on Substitute  Form W-9, which is provided under Item F, and to indicate
whether the Debenture  holder is subject to backup  withholding  by checking the
appropriate box in Part 2 of the form. Each Debenture  holder must date and sign
the  Substitute  Form  W-9 in the  spaces  indicated.  Failure  to  provide  the
information  on the form may  subject  the  Debenture  holder  to a $50  penalty
imposed by the  Internal  Revenue  Service  and to a 31% United  States  federal
income tax  withholding  on any cash payment he or she is otherwise  entitled to
receive  with  respect to  Debentures  received or amounts  paid for  fractional
Shares. The box in Part 3 of the form may be checked if the Debenture holder has
not been  issued a TIN and has  applied  for a number or  intends to apply for a
number in the near  future.  If the box in Part 3 is  checked,  the  Paying  and
Conversion  Agent may still  withhold  31% of all  payments  that the  Debenture
holder is  otherwise  entitled to receive  until a TIN is provided to the Paying
and Conversion Agent.

                           IMPORTANT TAX INFORMATION

     Under the United States  federal  income tax law, the Paying and Conversion
Agent may be required  to withhold 31 percent of the amount of any cash  payment
to  Debenture  holders  in  connection  with the  redemption  or  conversion  of
Debentures.  In order to avoid such  "backup  withholding,"  a Debenture  holder
whose Debentures are surrendered  herewith is required to provide the Paying and
Conversion Agent with such Debenture  holder's  current Taxpayer  Identification
Number  ("TIN")  on  Substitute  Form  W-9.  If  such  Debenture  holder  is  an
individual,  the TIN is his or her  social  security  number.  If the Paying and
Conversion  Agent is not provided with the correct TIN or an adequate  basis for
exemption,

                                       10


the  Debenture  holder may be subject to a $50 penalty  imposed by the  Internal
Revenue Service.  In addition,  any cash payment made to a Debenture holder with
respect to Debentures surrendered for redemption or conversion may be subject to
backup withholding.

     Certain Debenture holders  (including,  among others,  all corporations and
certain  foreign  individuals)  are not subject to these backup  withholding and
reporting  requirements.  In order for a foreign  individual  to  qualify  as an
exempt  recipient,  that Debenture  holder must submit a Form W-8,  signed under
penalties of perjury,  attesting to that individual's  exempt status. A Form W-8
can be obtained from the Paying and Conversion Agent.

     If backup withholding  applies, the Paying and Conversion Agent is required
to withhold 31% of any cash payment made to the Debenture holder with respect to
Debentures  surrendered for redemption or conversion.  Backup withholding is not
an additional  federal income tax. Rather, the tax liability of a person 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.

PURPOSES OF SUBSTITUTE FORM W-9

     To prevent backup  withholding,  the Debenture holder is required to notify
the Paying and Conversion Agent of his or her correct TIN on Substitute Form W-9
and certify  that the TIN  provided on  Substitute  Form W-9 is correct (or that
such Debenture  holder is awaiting a TIN) and that such Debenture  holder is not
otherwise subject to backup withholding.  In addition, the Debenture holder must
complete Part 2 of the Substitute W-9, check the  appropriate  box, and date and
sign the Substitute Form W-9 as indicated.

WHAT NUMBER TO GIVE THE PAYING AND CONVERSION AGENT

     The Debenture  holder is required to give the Paying and  Conversion  Agent
the social security number or employer identification number of the record owner
of the  Debentures  being  surrendered  for  redemption  or  conversion.  If the
Debentures 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.

     HOLDERS OF  DEBENTURES  ARE ADVISED TO READ THE  PROSPECTUS  AND TO CONSULT
THEIR OWN TAX  ADVISORS  REGARDING  THE  FEDERAL,  STATE,  LOCAL AND FOREIGN TAX
CONSEQUENCES OF THE CONVERSION OR REDEMPTION OF THE DEBENTURES IN LIGHT OF THEIR
OWN PARTICULAR CIRCUMSTANCES.
