         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
NOMINEE OF A DEPOSITARY. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED
IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE
LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS
SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE DEPOSITARY TO
A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY
OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO
A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY) MAY BE
REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES.

         UNLESS THIS GLOBAL SECURITY IS PRESENTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITARY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY DEFINITIVE SECURITY IS ISSUED IN THE NAME
OR NAMES AS DIRECTED IN WRITING BY THE DEPOSITARY, ANY TRANSFER, PLEDGE, OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL IN AS
MUCH AS THE REGISTERED OWNER HEREOF, THE DEPOSITARY, HAS AN INTEREST HEREIN.

         THIS SECURITY HAS BEEN INITIALLY RESOLD IN RELIANCE ON RULE 144A UNDER
THE SECURITIES ACT AND SHALL BEAR THE FOLLOWING LEGEND UNTIL REMOVABLE IN
ACCORDANCE WITH ITS TERMS AND THE TERMS OF THE INDENTURE:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY
NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO OR FOR THE ACCOUNT OR
BENEFIT OF U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
ACQUISITION HEREOF, EACH HOLDER OF THIS SECURITY AND ANY OWNERS OF INTERESTS
HEREIN (1) REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
IN RULE 144A UNDER THE SECURITIES ACT), (2) AGREES THAT BEGINNING FROM THE LATER

THE COMPANY OR ANY AFFILIATE THEREOF WAS THE BENEFICIAL OWNER OF THIS SECURITY
(OR ANY PREDECESSOR HEREOF) THROUGH THE TIME PERIOD REFERRED TO IN RULE 144(K)
UNDER THE SECURITIES ACT, IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY
EXCEPT (A) TO THE COMPANY OR ANY AFFILIATE THEREOF, (B) TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C)
TO AN INSTITUTIONAL "ACCREDITED INVESTOR" THAT PRIOR TO SUCH TRANSFER FURNISHED
TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN

                                  Exhibit A-1

REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
SECURITY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE) AND, IF
SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF SECURITIES AT
THE TIME OF TRANSFER OF LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE TO
THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (D)
OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT,
(E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH
PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT
OF THIS LEGEND. UNLESS THE COMPANY DETERMINES OTHERWISE IN ACCORDANCE WITH
APPLICABLE LAW, THIS LEGEND WILL BE REMOVED BY THE COMPANY (1) UPON REQUEST OF
THE HOLDER, AFTER THE EXPIRATION OF THE TIME PERIOD REFERRED TO IN RULE 144(K)
UNDER THE SECURITIES ACT BEGINNING FROM THE LATER OF (A) THE ORIGINAL ISSUE DATE
OF THIS SECURITY AND (B) THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE
THEREOF WAS THE BENEFICIAL OWNER OF THIS SECURITY (OR ANY PREDECESSOR HEREOF) OR
(2) WITH RESPECT TO SECURITIES SOLD IN RELIANCE ON REGULATION S, FOLLOWING THE
EXPIRATION OF 40 CONSECUTIVE DAYS BEGINNING ON AND INCLUDING THE LATER OF (A)
THE DAY ON WHICH INTERESTS IN THIS SECURITY ARE OFFERED TO PERSONS OTHER THAN
DISTRIBUTORS (AS DEFINED IN REGULATION S) AND (B) THE ORIGINAL ISSUE DATE OF
THIS SECURITY. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES"
AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE
SECURITIES ACT.

         MIDAMERICAN ENERGY HOLDINGS COMPANY, a corporation organized under the
laws of Iowa (herein called the "Company," which term includes any successor
corporation under the Indenture hereinafter referred to), for value received,
hereby promises to pay to CEDE & Co., or registered assigns, the principal
amount of [________] Dollars (such Initial Principal Amount, as it may from time
to time be adjusted by endorsement on Schedule A hereto, is hereinafter referred
to as the "Principal Amount") on February 15, 2014, and to pay interest thereon
from February 12, 2004, or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually on February 15 and
August 15 in each year, commencing August 15, 2004, at the rate of 5.00% per
annum, until the Principal Amount hereof is paid or made available for payment;
provided that any Principal Amount and premium, and any such installment of
interest, which is overdue shall bear interest at the rate of 5.00% per annum
(or, if lower, the maximum rate legally enforceable) from the dates such amounts
are due until they are paid or made available for payment; provided, further,
that if a Registration Default (as defined in the Registration Rights Agreement)
occurs with respect to this Security, interest will accrue on this Security at a
rate of 0.5% per annum from and including the date on which any such
Registration Default shall occur, until but excluding the date on which all
Registration Defaults have been cured. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the February 1 or August 1
(whether or not a Business Day), as the case may be, immediately preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Person in whose name this Security
(or one or more Predecessor Securities) is registered on such Regular Record
Date and may be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

         Payment of the principal of (and premium, if any) and interest, if any,
on this Security will be made at any place of payment or at the office or agency
of the Company maintained for that purpose in the Borough of Manhattan, The City
of New York, in such coin or currency of the United States as at the time of
payment is legal tender for the payment of public and private debts, provided,
however, that, payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security
Register. Payment of interest, if any, in respect of this Security may also be
made, in the case of a Holder of at least U.S. $1,000,000 aggregate principal
amount of Securities, by wire transfer to a U.S.

                                  Exhibit A-3

Dollar account maintained by the Holder with a bank in the United States;
provided that such Holder elects payment by wire transfer by giving written
notice to the Trustee or Paying Agent to such effect designating such account no
later than 15 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities of this series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day in New York City preceding such Redemption Date, as set forth in
the daily statistical release (or any successor release) published

                                  Exhibit A-7

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m.
Quotations for U.S. Government Securities" or (ii) if such release (or any
successor release) is not published or does not contain such prices on such
Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

of international standing appointed by the Company.

         "Reference Treasury Dealer" means a primary U.S. government securities

         "Reference Treasury Dealer Quotation" means, with respect to the

(expressed in each case as a percentage of its principal amount and quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in New York City preceding such Redemption Date).

         Notice of redemption pursuant to this paragraph 2 shall be given as
provided for in the Indenture not less than 30 days nor more than 60 days prior
to the Redemption Date.

         If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate.

         Unless the Company defaults in payment of the Redemption Price, from
and after the Redemption Date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect of such Securities of this series except the right to
receive the Redemption Price thereof.

         In the event of redemption of this Security in part only, the Trustee
will reduce the Principal Amount hereof by endorsement on Schedule A hereto such
that the Principal Amount shown on Schedule A after such endorsement will
reflect only the unredeemed portion hereof.

         3. DEFEASANCE

         The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities of
this series which has become due solely by

                                  Exhibit A-8

reason of such declaration of acceleration) then and in every such case, the
Holders of a majority in aggregate principal amount of the Outstanding
securities of such series may, by written notice to the Company and to the
Trustee, rescind and annul such declaration and its consequences on behalf of
all of the Holders, but no such rescission or annulment shall extend to or
affect any subsequent default or impair any right consequent thereon.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of
a receiver or trustee or for any other remedy thereunder, unless (a) such Holder

Default with respect to the Securities, (b) the Holders of not less than 33% or
a majority, as applicable, in principal amount of the Securities at the time
Outstanding under the Indenture shall have made written request to the Trustee

against the costs, expenses and liabilities to be incurred in compliance with
such request, (d) the Trustee shall not have received from the Holders of a
majority in principal amount of Securities at the time Outstanding under the
Indenture a direction inconsistent with such request and (e) the Trustee for 90
days after its receipt of such notice and offer of indemnity from the Holder,
and request from the Holders, shall have failed to institute any such
proceeding. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         5. AMENDMENT AND WAIVER

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and rights of the Holders
of the Securities of any series at any time by the Company and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

                                  Exhibit A-9

         6. TRANSFER AND EXCHANGE; DENOMINATIONS

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of a Security of the series of which this Security is a
part is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place
where the principal of (and premium, if any) and interest, if any, on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

         The Securities of the series of which this Security is a part are
issuable only in registered form, without coupons, in denominations of $1,000
and any integral multiple of $1,000.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         7. SUCCESSOR OBLIGORS

         When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

         8. TRUSTEE DEALINGS WITH THE COMPANY

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

         9. NO RECOURSE AGAINST OTHERS

         No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

         10. AUTHENTICATION

                                                                       EXHIBIT B

                     FORM OF FACE OF REGULATION S TEMPORARY
                           GLOBAL SENIOR NOTE DUE 2014

         THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL SECURITY,
AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR DEFINITIVE
SECURITIES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE
HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL SECURITY
SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON.

         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
NOMINEE OF A DEPOSITARY. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED

LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS
SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE DEPOSITARY TO

TO AN INSTITUTIONAL "ACCREDITED INVESTOR" THAT PRIOR TO SUCH TRANSFER FURNISHED
TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH
LETTER CAN BE OBTAINED FROM THE TRUSTEE) AND, IF SUCH TRANSFER IS IN RESPECT OF
AN AGGREGATE PRINCIPAL AMOUNT OF SECURITIES AT THE TIME OF TRANSFER OF LESS THAN
$250,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS
IN COMPLIANCE WITH THE SECURITIES ACT, (D) OUTSIDE THE UNITED STATES IN
COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION
FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE)
OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS
TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. UNLESS THE
COMPANY DETERMINES OTHERWISE IN ACCORDANCE WITH APPLICABLE LAW, THIS LEGEND WILL
BE REMOVED BY THE COMPANY (1) UPON REQUEST OF THE HOLDER, AFTER THE EXPIRATION
OF THE TIME PERIOD REFERRED TO IN RULE 144(K) UNDER THE SECURITIES ACT BEGINNING
FROM THE LATER OF (A) THE ORIGINAL ISSUE DATE OF THIS SECURITY AND (B) THE LAST
DATE ON WHICH THE COMPANY OR ANY AFFILIATE THEREOF WAS THE BENEFICIAL OWNER OF
THIS SECURITY (OR ANY PREDECESSOR HEREOF) OR (2) WITH RESPECT TO SECURITIES SOLD
IN RELIANCE ON REGULATION S, FOLLOWING THE EXPIRATION OF 40 CONSECUTIVE DAYS
BEGINNING ON AND INCLUDING THE LATER OF (A) THE DAY ON WHICH INTERESTS IN THIS
SECURITY ARE OFFERED TO PERSONS OTHER THAN DISTRIBUTORS (AS DEFINED IN
REGULATION S) AND (B) THE ORIGINAL ISSUE DATE OF THIS SECURITY. AS USED HEREIN,
THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE
MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         MIDAMERICAN ENERGY HOLDINGS COMPANY, a corporation organized under the
laws of Iowa (the "Company," which term includes any successor corporation under
the Indenture hereinafter referred to), for value received, hereby promises to
pay to CEDE & Co., or registered assigns, the principal amount of [__________]
Dollars (such Initial Principal Amount, as it may from time to time be adjusted
by endorsement on Schedule A hereto, is hereinafter referred to as the
"Principal Amount"), on February 15, 2014, and to pay interest thereon from
February 12, 2004, or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually on February 15 and
August 15 in each year, commencing August 15, 2004, at the rate of 5.00% per
annum, until the Principal Amount hereof is paid or made available for payment;
provided that any Principal Amount and premium, and any such installment of
interest, which is overdue shall bear interest at the rate of 5.00% per annum
(or, if lower, the maximum rate legally enforceable) from the dates such amounts
are due until they are paid or made available for payment; provided, further,
that if a Registration Default (as defined in the Registration Rights Agreement)
occurs with respect to this Security, interest will accrue on this Security at a
rate of 0.5% per annum from and including the date on which any such
Registration Default shall occur, until but excluding the date on which all
Registration Defaults have been cured. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the February 1 or August 1
(whether or not a Business Day), as the case may be, immediately preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Person in whose name this Security
(or one or more Predecessor Securities) is registered on such Regular Record
Date and may be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

         Until this Regulation S Temporary Global Security is exchanged for one
or more Regulation S Permanent Global Securities, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Security shall in all other respects be
entitled to the same benefits as other Securities under the Indenture.

         Payment of the principal of (and premium, if any) and interest, if any,

maintained for that purpose in the Borough of Manhattan, The City of New York,
in such coin or currency of the United States as at the time of payment is legal
tender for the payment of public and private debts, provided, however, that
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register. Payment
of interest, if any, in respect of this Security may also be made, in the case
of a Holder of at least U.S. $1,000,000 aggregate principal amount of
Securities, by wire transfer to a U.S. Dollar account maintained by the Holder
with a bank in the United States; provided that such Holder elects payment by
wire transfer by giving written notice to the Trustee or Paying Agent to such
effect designating such account no later than 15 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly

                           5.00% Senior Notes due 2014

         1. GENERAL

         This Security is one of a duly authorized issue of securities of the
Company (the "Securities"), issued and to be issued in one or more series under
an Indenture, dated as of October 4, 2002 (as amended by Article IV of the
Second Supplemental Indenture thereto, dated as of May 16, 2003, the "Base
Indenture"), between the Company and The Bank of New York as trustee (the
"Trustee," which term includes any successor trustee under the Base Indenture),
as supplemented by the Third Supplemental Indenture, dated as of February 12,
2004 (together with the Base Indenture, the "Indenture") between the Company and
the Trustee, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. Terms defined in the Indenture which are
not defined herein are used with the meanings assigned to them in the Indenture.
This Security is one of the series designated on the face hereof.

         2. OPTIONAL REDEMPTION

         The Securities of this series are subject to redemption upon not less
than 30 or more than 60 days' notice to the Holders of such Securities as
provided in the Indenture, at any time, as a whole or in part, at the election
of the Company, at a redemption price equal to the greater of: (i) 100% of the
principal amount of the Securities of this series being redeemed or (ii) the sum
of the present values of the remaining scheduled payments of principal of and
interest on the Securities of this series being redeemed discounted to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at a discount rate equal to the Treasury Yield plus 20
basis points, plus, for (i) or (ii) above, whichever is applicable, accrued
interest on the Securities of this series to the Redemption Date.

         "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities of this series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day in New York City preceding such

                                  Exhibit B-7

Redemption Date, as set forth in the daily statistical release (or any successor
release) published by the Federal Reserve Bank of New York and designated
"Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such
release (or any successor release) is not published or does not contain such
prices on such Business Day, the Reference Treasury Dealer Quotation for such
Redemption Date.

         "Independent Investment Banker" means an investment banking institution
of international standing appointed by the Company.

         "Reference Treasury Dealer" means a primary U.S. government securities
dealer in New York City appointed by the xCompany.

         "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Company, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in New York City preceding such Redemption Date).

         Notice of redemption pursuant to this paragraph 2 shall be given as
provided for in the Indenture not less than 30 days nor more than 60 days prior
to the Redemption Date.

         If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate.

         Unless the Company defaults in payment of the Redemption Price, from
and after the Redemption Date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect of such Securities of this series except the right to
receive the Redemption Price thereof.

         In the event of redemption of this Security in part only, the Trustee
will reduce the Principal Amount hereof by endorsement on Schedule A hereto such
that the Principal Amount shown on Schedule A after such endorsement will
reflect only the unredeemed portion hereof.

         3. DEFEASANCE

         The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

         4. DEFAULTS AND REMEDIES

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than

                                  Exhibit B-8

the non-payment of principal of the Securities of this series which has become
due solely by reason of such declaration of acceleration) then, and in every
such case, the Holders of a majority in aggregate principal amount of the
Outstanding securities under the Indenture may, by written notice to the Company
and to the Trustee, rescind and annul such declaration and its consequences on
behalf of all of the Holders, but no such rescission or annulment shall extend
to or affect any subsequent default or impair any right consequent thereon.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of
a receiver, or trustee or for any other remedy thereunder, unless (a) such
Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the securities, (b) the Holders of not less
than 33% or a majority, as applicable, in principal amount of the Securities at
the time Outstanding under the Indenture shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the
Trustee against the costs, expenses and liabilities to be incurred in compliance
with such request, (d) the Trustee shall not have received from the Holders of a
majority in principal amount of Securities at the time Outstanding under the
Indenture a direction inconsistent with such request and (e) the Trustee for 90
days after its receipt of such notice and offer of indemnity from the Holder,
and request from the Holders, shall have failed to institute any such
proceeding. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         5. AMENDMENT AND WAIVER

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and rights of the Holders
of the Securities of any series at any time by the Company and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

                                  Exhibit B-9

         6. TRANSFER AND EXCHANGE; DENOMINATIONS

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of a Security of the series of which this Security is a
part is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place
where the principal of (and premium, if any) and interest, if any, on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

         The Securities of the series of which this Security is a part are
issuable only in registered form, without coupons, in denominations of $1,000
and any integral multiple of $1,000.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         This Regulation S Temporary Global Security is exchangeable in whole or
in part for one or more Global Securities only (i) on or after the termination
of the 40-day distribution compliance period (as defined in Regulation S) and
(ii) upon presentation of certificates (accompanied by an Opinion of Counsel, if
applicable) required by Article 2 of the Indenture. Upon exchange of this
Regulation S Temporary Global Security for one or more Global Securities, the
Trustee shall cancel this Regulation S Temporary Global Security.

         7. SUCCESSOR OBLIGORS

         When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

         8. TRUSTEE DEALINGS WITH THE COMPANY

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

                                  Exhibit B-10

the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of

releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

         MIDAMERICAN ENERGY HOLDINGS COMPANY, a corporation organized under the
laws of Iowa (the "Company," which term includes any successor corporation under
the Indenture hereinafter referred to), for value received, hereby promises to
pay to CEDE & Co., or registered assigns, the principal amount of [__________]
Dollars (such Initial Principal Amount, as it may from time to time be adjusted
by endorsement on Schedule A hereto, is hereinafter referred to as the
"Principal Amount"), on February 15, 2014, and to pay interest thereon from
February 12, 2004, or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually on February 15 and
August 15 in each year, commencing August 15, 2004 at the rate of 5.00% per
annum until the Principal Amount hereof is paid or made available for payment;
provided that any Principal Amount and premium, and any such installment of
interest, which is overdue shall bear interest at the rate of 5.00% per annum
(or, if lower, the maximum rate legally enforceable) from the dates such amounts
are due until they are paid or made available for payment; provided, further,
that if a Registration Default (as defined in the Registration Rights Agreement)
occurs with respect to this Security, interest will accrue on this Security at a
rate of 0.5% per annum from and including the date on which any such
Registration Default shall occur, until but excluding the date on which all
Registration Defaults have been cured. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the February 1 or August 1
(whether or not a Business Day), as the case may be, immediately preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Person in whose name this Security
(or one or more Predecessor Securities) is registered on such Regular Record
Date and may be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

payment is legal tender for the payment of public and private debts, provided,
however, that payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security
Register. Payment of interest, if any, in respect of this Security may also be
made, in the case of a Holder of at least U.S. $1,000,000 aggregate principal
amount of Securities, by wire transfer to a U.S.

                                  Exhibit C-2

provided that such Holder elects payment by wire transfer by giving written
notice to the Trustee or Paying Agent to such effect designating such account no
later than 15 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                           5.00% Senior Notes due 2014

         1. GENERAL

         This Security is one of a duly authorized issue of securities of the
Company (the "Securities"), issued and to be issued in one or more series under
an Indenture, dated as of October 4, 2002 (as amended by Article IV of the
Second Supplemental Indenture thereto, dated as of May 16, 2003, the "Base
Indenture"), between the Company and The Bank of New York as trustee (the
"Trustee," which term includes any successor trustee under the Base Indenture),
as supplemented by the Third Supplemental Indenture, dated as of February 12,
2004 (together with the Base Indenture, the "Indenture") between the Company and
the Trustee, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. Terms defined in the Indenture which are
not defined herein are used with the meanings assigned to them in the Indenture.
This Security is one of the series designated on the face hereof.

         2. OPTIONAL REDEMPTION

         The Securities of this series are subject to redemption upon not less
than 30 or more than 60 days' notice to the Holders of such Securities as
provided in the Indenture, at any time, as a whole or in part, at the election
of the Company at any time, at a redemption price equal to the greater of: (i)
100% of the principal amount of the Securities of this series being redeemed or
(ii) the sum of the present values of the remaining scheduled payments of
principal of and interest on the Securities of this series being redeemed
discounted to the Redemption Date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at a discount rate equal to the Treasury
Yield plus 20 basis points, plus, for (i) or (ii) above, whichever is
applicable, accrued interest on the Securities of this series to the Redemption
Date.

         "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities of this series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day in New York City preceding such

                                  Exhibit C-6

Redemption Date, as set forth in the daily statistical release (or any successor
release) published by the Federal Reserve Bank of New York and designated
"Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such
release (or any successor release) is not published or does not contain such
prices on such Business Day, the Reference Treasury Dealer Quotation for such
Redemption Date.

         "Independent Investment Banker" means an investment banking institution
of international standing appointed by the Company.

         "Reference Treasury Dealer" means a primary U.S. government securities
dealer in New York City appointed by the Company.

         "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Company, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in New York City preceding such Redemption Date).

         Notice of redemption pursuant to this paragraph 2 shall be given as
provided for in the Indenture not less than 30 days nor more than 60 days prior
to the Redemption Date.

         If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate.

         Unless the Company defaults in payment of the Redemption Price, from
and after the Redemption Date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect of such Securities of this series except the right to
receive the Redemption Price thereof.

         In the event of redemption of this Security in part only, the Trustee
will reduce the Principal Amount hereof by endorsement on Schedule A hereto such
that the Principal Amount shown on Schedule A after such endorsement will
reflect only the unredeemed portion hereof.

         3. DEFEASANCE

         The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

         4. DEFAULTS AND REMEDIES

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than

                                  Exhibit C-7

the non-payment of principal of the Securities of this series which has become
due solely by reason of such declaration of acceleration) then, and in every
such case, the Holders of a majority in aggregate principal amount of the
Outstanding securities of such series may, by written notice to the Company and
to the Trustee, rescind and annul such declaration and its consequences on
behalf of all of the Holders, but no such rescission or annulment shall extend
to or affect any subsequent default or impair any right consequent thereon.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of
a receiver, or trustee or for any other remedy thereunder, unless (a) such
Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the securities, (b) the Holders of not less
than 33% or a majority, as applicable, in principal amount of the Securities at
the time Outstanding under the Indenture shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the
Trustee against the costs, expenses and liabilities to be incurred in compliance
with such request, (d) the Trustee shall not have received from the Holders of a
majority in principal amount of Securities at the time Outstanding under the
Indenture a direction inconsistent with such request and (e) the Trustee for 90
days after its receipt of such notice and offer of indemnity from the Holder,
and request from the Holders shall have failed to institute any such proceeding.
The foregoing shall not apply to certain suits described in the Indenture,
including any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein.

         5. AMENDMENT AND WAIVER

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and rights of the Holders
of the Securities of any series at any time by the Company and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

                                  Exhibit C-8

         6. TRANSFER AND EXCHANGE; DENOMINATIONS

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of a Security of the series of which this Security is a
part is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place
where the principal of (and premium, if any) and interest, if any, on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of this series and like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

         The Securities of the series of which this Security is a part are
issuable only in registered form, without coupons, in denominations of $1,000
and any integral multiple of $1,000.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         7. SUCCESSOR OBLIGORS

         When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

         8. TRUSTEE DEALINGS WITH THE COMPANY

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

         9. NO RECOURSE AGAINST OTHERS

         No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

         10. AUTHENTICATION

name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted

                       MIDAMERICAN ENERGY HOLDINGS COMPANY
                           5.00% Senior Notes due 2014

         1. GENERAL

         This Security is one of a duly authorized issue of Securities of the
Company (the "Securities"), issued and to be issued in one or more series under
an Indenture, dated as of October 4, 2002 (as amended by Article IV of the
Second Supplemental Indenture thereto, dated as of May 16, 2003, the "Base
Indenture"), between the Company and The Bank of New York, as trustee (the
"Trustee," which term includes any successor trustee under the Base Indenture),
as supplemented by the Third Supplemental Indenture, dated as of February 12,
2004 (together with the Base Indenture, the "Indenture") between the Company and
the Trustee, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. Terms defined in the Indenture which are
not defined herein are used with the meanings assigned to them in the Indenture.
This Security is one of the series designated on the face hereof.

         2. OPTIONAL REDEMPTION

         The Securities of this series are subject to redemption upon not less
than 30 or more than 60 days' notice to the Holders of such Securities as
provided in the Indenture, at any time, as a whole or in part, at the election
of the Company, at a redemption price equal to the greater of: (i) 100% of the
principal amount of the Securities of this series being redeemed or (ii) the sum
of the present values of the remaining scheduled payments of principal of and
interest on the Securities of this series being redeemed discounted to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at a discount rate equal to the Treasury Yield plus 20
basis points, plus, for (i) or (ii) above, whichever is applicable, accrued
interest on the Securities of this series to the Redemption Date.

         "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities of this series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day in New York City preceding such Redemption Date, as set forth in
the daily statistical release (or any successor release) published

                                  Exhibit D-7

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m.
Quotations for U.S. Government Securities" or (ii) if such release (or any
successor release) is not published or does not contain such prices on such
Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

         "Independent Investment Banker" means an investment banking institution
of international standing appointed by the Company.

         "Reference Treasury Dealer" means a primary U.S. government securities
dealer in New York City appointed by the Company.

         "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Company, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in New York City preceding such Redemption Date).

         Notice of redemption pursuant to this paragraph 2 shall be given as
provided for in the Indenture not less than 30 days nor more than 60 days prior
to the Redemption Date.

         If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate.

         Unless the Company defaults in payment of the Redemption Price, from
and after the Redemption Date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect of such Securities of this series except the right to
receive the Redemption Price thereof.

         3. DEFEASANCE

         The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

         4. DEFAULTS AND REMEDIES

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities of
this series which has become due solely by reason of such declaration of
acceleration) then and in every such case, the Holders of a majority in
aggregate principal amount of the Outstanding securities of such series may, by
written notice to the Company and to the Trustee, rescind and annul such
declaration and its consequences on

                                  Exhibit D-8

behalf of all of the Holders, but no such rescission or annulment shall extend
to or affect any subsequent default or impair any right consequent thereon.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of
a receiver or trustee or for any other remedy thereunder, unless (a) such Holder
shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities, (b) the Holders of not less than 33% or
a majority, as applicable, in principal amount of the Securities at the time
Outstanding under the Indenture shall have made written request to the Trustee
to institute proceedings in respect of such Event of Default as Trustee, (c)
such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
against the costs, expenses and liabilities to be incurred in compliance with
such request, (d) the Trustee shall not have received from the Holders of a
majority in principal amount of Securities at the time Outstanding under the
Indenture a direction inconsistent with such request and (e) the Trustee for 90
days after its receipt of such notice and offer of indemnity from the Holder,
and request from the Holders, shall have failed to institute any such
proceeding. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         5. AMENDMENT AND WAIVER

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and rights of the Holders
of the Securities of any series at any time by the Company and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

         6. TRANSFER AND EXCHANGE; DENOMINATIONS

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of a Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the

                                  Exhibit D-9

principal of (and premium, if any) and interest, if any, on this Security are
payable, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

         The Securities of the series of which this Security is a part are
issuable only in registered form, without coupons, in denominations of $1,000
and any integral multiple of $1,000.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         7. SUCCESSOR OBLIGORS

         When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

         8. TRUSTEE DEALINGS WITH THE COMPANY

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

         9. NO RECOURSE AGAINST OTHERS

         No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

         10. AUTHENTICATION

         This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

                                  Exhibit D-10

         11. CUSIP NUMBERS

         This Security shall be governed by and construed in accordance with the
laws of the State of New York, including Section 5-1401 of the New York General
Obligations Law, but otherwise without regard to the principles of conflict of
laws thereof.

interest has been paid or duly provided for, semi-annually on February 15 and
August 15 in each year, commencing August 15, 2004, at the rate of 5.00% per
annum, until the Principal Amount hereof is paid or made available for payment;
provided that any Principal Amount and premium, and any such installment of
interest, which is overdue shall bear interest at the rate of 5.00% per annum

Security (or one or more Predecessor Securities) is registered at the close of

registered on such Regular Record Date and may be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted

Securities of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with

payment is legal tender for the payment of public and private debts, provided,
however, that, payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security
Register. Payment of interest, if any, in respect of this Security may also be
made, in the case of a Holder

of at least U.S. $1,000,000 aggregate principal amount of Securities, by wire
transfer to a U.S. Dollar account maintained by the Holder with a bank in the

such account no later than 15 days immediately preceding the relevant due date
for payment (or such other date as the Trustee may accept in its discretion).

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities of this series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as

                                   Exhibit E-5

a percentage of its principal amount) on the third Business Day in New York City
preceding such Redemption Date, as set forth in the daily statistical release
(or any successor release) published by the Federal Reserve Bank of New York and
designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or
(ii) if such release (or any successor release) is not published or does not
contain such prices on such Business Day, the Reference Treasury Dealer
Quotation for such Redemption Date.

         "Independent Investment Banker" means an investment banking institution
of international standing appointed by the Company.

         "Reference Treasury Dealer" means a primary U.S. government securities
dealer in New York City appointed by the Company.

         "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Company, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in New York City preceding such Redemption Date).

         Notice of redemption pursuant to this paragraph 2 shall be given as
provided for in the Indenture not less than 30 days nor more than 60 days prior
to the Redemption Date.

         If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate.

         Unless the Company defaults in payment of the Redemption Price, from
and after the Redemption Date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect of such Securities of this series except the right to
receive the Redemption Price thereof.

         3. DEFEASANCE

         The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

         4. DEFAULTS AND REMEDIES

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities of
this series which has become due solely by reason of such declaration of
acceleration) then and in every such case, the Holders of a majority in
aggregate principal amount of the Outstanding securities of such series may, by
written notice

                                  Exhibit E-6

to the Company and to the Trustee, rescind and annul such declaration and its
consequences on behalf of all of the Holders, but no such rescission or
annulment shall extend to or affect any subsequent default or impair any right
consequent thereon.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of
a receiver or trustee or for any other remedy thereunder, unless (a) such Holder
shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities, (b) the Holders of not less than 33% or
a majority, as applicable, in principal amount of the Securities at the time
Outstanding under the Indenture shall have made written request to the Trustee
to institute proceedings in respect of such Event of Default as Trustee, (c)
such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
against the costs, expenses and liabilities to be incurred in compliance with
such request, (d) the Trustee shall not have received from the Holders of a
majority in principal amount of Securities at the time Outstanding under the
Indenture a direction inconsistent with such request and (e) the Trustee for 90
days after its receipt of such notice and offer of indemnity from the Holder,
and request from the Holders, shall have failed to institute any such
proceeding. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         5. AMENDMENT AND WAIVER

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and rights of the Holders
of the Securities of any series at any time by the Company and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

         6. TRANSFER AND EXCHANGE; DENOMINATIONS

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security

                                  Exhibit E-7

is registrable in the Security Register, upon surrender of this Security for
registration of transfer at the office or agency of the Company in any place
where the principal of (and premium, if any) and interest, if any, on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

         The Securities of the series of which this Security is a part are
issuable only in registered form, without coupons, in denominations of $1,000
and any integral multiple of $1,000.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         7. SUCCESSOR OBLIGORS

         When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

         8. TRUSTEE DEALINGS WITH THE COMPANY

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

         9. NO RECOURSE AGAINST OTHERS

         No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

         10. AUTHENTICATION

         This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

                                  Exhibit E-8

         11. CUSIP NUMBERS

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company will cause CUSIP numbers to be

Securities of this series.

         12. GOVERNING LAW

         This Security shall be governed by and construed in accordance with the
laws of the State of New York, including Section 5-1401 of the New York General
Obligations Law, but otherwise without regard to the principles of conflict of
laws thereof.

         13. DEFINED TERMS

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

                                  Exhibit E-9

CREDIT SUISSE FIRST BOSTON LLC
Eleven Madison Avenue
New York, New York 10010-3629

LEHMAN BROTHERS INC.
745 Seventh Avenue
New York, New York 10019

Dear Sirs:

         MidAmerican Energy Holdings Company, an Iowa corporation (the
"COMPANY"), proposes to issue and sell to the several initial purchasers, Credit
Suisse First Boston LLC and Lehman Brothers Inc. (together, the "INITIAL
PURCHASERS"), upon the terms set forth in a purchase agreement of even date
herewith (the "PURCHASE AGREEMENT"), $250,000,000 aggregate principal amount of
its 5.00% Senior Notes due February 15, 2014 (the "INITIAL Securities"). The
Initial Securities will be issued pursuant to that certain Indenture, dated as
of October 4, 2002, as amended by Article IV of the Second Supplemental
Indenture thereto dated as of May 16, 2003 and as supplemented by a third
supplemental indenture to be entered into thereunder to be dated on or about
February 12, 2004 (collectively, the "INDENTURE"), between the Company and The
Bank of New York, as trustee (the "TRUSTEE"). As an inducement to the Initial
Purchasers to enter into the Purchase Agreement, the Company agrees with the
Initial Purchasers, for the benefit of the Initial Purchasers and the holders of
the Securities (as defined below) (collectively, the "HOLDERS"), as follows:

         1. Registered Exchange Offer. Unless not permitted by applicable law
(after the Company has complied with the ultimate paragraph of this Section 1),
the Company shall prepare and file with the Securities and Exchange Commission
(the "COMMISSION") a registration statement (the "EXCHANGE OFFER REGISTRATION
STATEMENT") on an appropriate form under the Securities Act of 1933, as amended
(the "SECURITIES ACT"), with respect to a proposed offer (the "REGISTERED
EXCHANGE OFFER") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission
from participating in the Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Initial Securities, a like aggregate principal
amount of debt securities of the Company issued under the Indenture,
substantially identical in all material respects to the Initial Securities and
registered under the Securities Act (the "EXCHANGE SECURITIES"). The Company
shall use its reasonable best efforts to cause the Exchange Offer Registration
Statement to become effective under the Securities Act within 270 days (such
270th day being an "EFFECTIVENESS DEADLINE") after the date on which the Initial
Purchasers purchase the Initial Securities pursuant to the Purchase Agreement
(the "CLOSING

DATE") and will keep the Exchange Offer Registration Statement effective for not
less than 30 days (or longer, if required by applicable law) after the date
notice of the Registered Exchange Offer is mailed to the Holders (such period
being called the "EXCHANGE OFFER REGISTRATION PERIOD").

         If the Company commences the Registered Exchange Offer, the Company
will be entitled to consummate the Registered Exchange Offer 30 days after such
commencement (provided that the Company has accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer).

         Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of the Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Securities in the ordinary course of such Holder's business and has no
arrangements or understanding with any person to participate in the distribution
of the Exchange Securities and is not prohibited by any law or policy of the
Commission from participating in the Registered Exchange Offer) to trade such
Exchange Securities from and after their receipt without any limitations or
restrictions under the Securities Act.

         The Company acknowledges that, pursuant to current interpretations by
the Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Initial Securities, acquired for its own account as a
result of market making activities or other trading activities, for Exchange
Securities (an "EXCHANGING DEALER"), is required to deliver a prospectus
containing the information set forth in (a) Annex A hereto on the cover, (b)
Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of
the Exchange Offer" section, and (c) Annex C hereto in the "Plan of
Distribution" section of such prospectus in connection with a sale of any such
Exchange Securities received by such Exchanging Dealer pursuant to the
Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Securities (as defined below) acquired in exchange for Initial Securities
constituting any portion of an unsold allotment, is required to deliver a
prospectus containing the information required by Items 507 or 508, as
applicable, of Regulation S-K under the Securities Act in connection with such
sale.

         The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchaser, such period
shall be the lesser of 120 days and the date on which all Exchanging Dealers and
the Initial Purchasers have sold all Exchange Securities held by them (unless
such period is extended pursuant to Section 3(j) below) and (ii) the Company
shall make such prospectus and any amendment or supplement thereto available to
any broker-dealer for use in connection with any resale of any Exchange
Securities for a period of not less than 120 days after the consummation of the
Registered Exchange Offer.

         If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "PRIVATE EXCHANGE") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and substantially identical in all material respects
to the Initial Securities (the "PRIVATE EXCHANGE Securities"). The Initial
Securities, the Exchange Securities and the Private Exchange Securities are
herein collectively called the "SECURITIES".

                                       2

         In connection with the Registered Exchange Offer, the Company shall:

                  (a) mail to each Holder a copy of the prospectus forming part
         of the Exchange Offer Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                  (b) keep the Registered Exchange Offer open for not less than
         30 days (or longer, if required by applicable law) after the date
         notice thereof is mailed to the Holders;

                  (c) utilize the services of a depositary for the Registered
         Exchange Offer with an address in the Borough of Manhattan, The City of
         New York, which may be the Trustee or an affiliate of the Trustee;

                  (d) permit Holders to withdraw tendered Securities at any time
         prior to the close of business, New York time, on the last business day
         on which the Registered Exchange Offer shall remain open; and

                  (e) otherwise comply with all applicable laws.

         As soon as practicable after the close of the Registered Exchange Offer
or the Private Exchange, as the case may be, the Company shall:

                  (x) accept for exchange all the Initial Securities validly
         tendered and not withdrawn pursuant to the Registered Exchange Offer
         and the Private Exchange;

                  (y) deliver to the Trustee for cancellation all the Initial
         Securities so accepted for exchange; and

                  (z) cause the Trustee to authenticate and deliver promptly to
         each Holder of the Initial Securities, the Exchange Securities or the
         Private Exchange Securities, as the case may be, equal in principal
         amount to the Initial Securities of such Holder so accepted for
         exchange.

         The Indenture will provide that the Exchange Securities will not be
subject to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

         Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.

         Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of its business, (ii) at the time of
commencement of the Registered Exchange Offer, such Holder had no arrangements
or understanding with any person to participate in the distribution of the
Securities or the Exchange Securities within the meaning of the Securities Act,
(iii) such Holder is not an "affiliate," as defined in Rule 405 of the
Securities Act, of the Company or if it is an affiliate, such Holder will comply
with the registration and prospectus delivery requirements of the Securities Act
to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is
not engaged in, and does not intend to engage in, the distribution of the
Exchange Securities and (v) if such Holder is a broker-dealer, that it will
receive Exchange Securities for its own account in exchange for Initial
Securities that were acquired as a result of market-making activities or other
trading activities and

                                       3

that it will be required to acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Securities.

         Notwithstanding any other provisions hereof, the Company will ensure
that (i) any Exchange Offer Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto does not, when it becomes effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

         If following the date hereof there has been announced a change in
Commission policy with respect to exchange offers that in the reasonable opinion
of counsel to the Company raises a substantial question as to whether the
Registered Exchange Offer is permitted by applicable federal law, the Company
will seek a no-action letter or other favorable decision from the Commission
allowing the Company to consummate the Registered Exchange Offer. The Company
will pursue the issuance of such a decision to the Commission staff level. In
connection with the foregoing, the Company will take all such other actions as
may be requested by the Commission or otherwise reasonably required in
connection with the issuance of such decision, including without limitation (i)
participating in telephonic conferences with the Commission, (ii) delivering to
the Commission staff an analysis prepared by counsel to the Company setting
forth the legal bases, if any, upon which such counsel has concluded that the
Registered Exchange Offer should be permitted and (iii) diligently pursuing a
resolution (which need not be favorable) by the Commission staff.

         2. Shelf Registration. If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated by the
date that is 40 days after the date on which the Exchange Offer Registration
Statement is declared effective (such 40th day being the "CONSUMMATION
DEADLINE"), (iii) any Initial Purchaser so requests with respect to the Initial
Securities (or the Private Exchange Securities) not eligible to be exchanged for
Exchange Securities in the Registered Exchange Offer and held by it following
consummation of the Registered Exchange Offer or (iv) any Holder (other than an
Exchanging Dealer) is not eligible to participate in the Registered Exchange
Offer or, in the case of any Holder (other than an Exchanging Dealer) that
participates in the Registered Exchange Offer, such Holder does not receive
freely tradeable Exchange Securities on the date of the exchange and any such
Holder so requests for any reason other than the failure by such Holder to make
a timely and valid tender in accordance with the Registered Exchange Offer, the
Company shall take the following actions (the date on which any of the
conditions described in the foregoing clauses (i) through (iv) occur, including
in the case of clauses (iii) or (iv) the receipt of the required notice, being a
"TRIGGER DATE"):

                  (a) The Company shall as promptly as practicable prepare and
         file with the Commission and thereafter use its reasonable best efforts
         to cause to be declared effective not later than the latter to occur of
         the date that is (i) 150 days after the Trigger Date and (ii) 270 days
         after the Closing Date (such 150th or 270th day, as the case may be,
         being an "EFFECTIVENESS DEADLINE"), a registration statement (the
         "SHELF REGISTRATION STATEMENT" and, together with the Exchange Offer
         Registration Statement, a "REGISTRATION STATEMENT") on an appropriate
         form under the Securities Act relating to the offer and sale of the
         Transfer Restricted Securities by the Holders thereof from time to time
         in accordance with the methods of distribution set forth in the Shelf
         Registration Statement and Rule 415 under the Securities Act
         (hereinafter, the "SHELF REGISTRATION"); provided, however, that no
         Holder (other than an Initial Purchaser) shall be entitled to have the
         Securities

                                       4

         held by it covered by the Shelf Registration Statement unless such
         Holder agrees in writing to be bound by all the provisions of this
         Agreement applicable to such Holder.

                  (b) The Company shall use its reasonable best efforts to keep
         the Shelf Registration Statement continuously effective in order to
         permit the prospectus included therein to be lawfully delivered by the
         Holders of the relevant Securities, for a period of two years (or for
         such longer period if extended pursuant to Section 3(j) below) from the
         Closing Date or such shorter period that will terminate when all the
         Securities covered by the Shelf Registration Statement (i) have been
         sold pursuant thereto or (ii) are no longer restricted securities (as
         defined in Rule 144 under the Securities Act, or any successor rule
         thereof) (such applicable period being called the "SHELF REGISTRATION
         PERIOD").

                  (c) Notwithstanding any other provisions of this Agreement to
         the contrary, the Company shall cause the Shelf Registration Statement
         and the related prospectus and any amendment or supplement thereto, as
         of the effective date of the Shelf Registration Statement, amendment or
         supplement, (i) to comply in all material respects with the applicable
         requirements of the Securities Act and the rules and regulations of the
         Commission promulgated thereunder and (ii) not to contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading.

         3. Registration Procedures. In connection with any Shelf Registration
Statement contemplated by Section 2 hereof and, to the extent applicable, any
Registered Exchange Offer contemplated by Section 1 hereof, the following
provisions shall apply:

                  (a) The Company shall (i) furnish to each Initial Purchaser,

         Registration Statement and each amendment thereof and each supplement,
         if any, to the prospectus included therein and, in the event that an
         Initial Purchaser (with respect to any portion of an unsold allotment
         from the original offering of the Initial Securities) is participating
         in the Registered Exchange Offer or the Shelf Registration Statement,
         the Company shall use its best efforts to reflect in each such
         document, when so filed with the Commission, such comments as such
         Initial Purchaser reasonably may propose not later than five business
         days after delivery of such documents to such Initial Purchaser; (ii)
         include the information set forth in Annex A hereto on the cover, in
         Annex B hereto in the "Exchange Offer Procedures" section and the
         "Purpose of the Exchange Offer" section and in Annex C hereto in the
         "Plan of Distribution" section of the prospectus forming a part of the
         Exchange Offer Registration Statement and include the information set
         forth in Annex D hereto in the letter of transmittal delivered pursuant
         to the Registered Exchange Offer; (iii) if requested by an Initial
         Purchaser, include the information required by Items 507 or 508, as

         prospectus forming a part of the Exchange Offer Registration Statement;
         (iv) include within the prospectus contained in the Exchange Offer
         Registration Statement a section entitled "Plan of Distribution,"
         reasonably acceptable to the Initial Purchasers, which shall contain a
         summary statement of the positions taken or policies made by the staff
         of the Commission with respect to the potential "underwriter" status of
         any broker-dealer that is the beneficial owner (as defined in Rule
         13d-3 under the Securities Exchange Act of 1934, as amended (the
         "EXCHANGE ACT")) of Exchange Securities received by such broker-dealer
         in the Registered Exchange Offer (a "PARTICIPATING BROKER-DEALER"),
         whether such positions or policies have been publicly disseminated by
         the staff of the Commission or such positions or policies, in the
         reasonable judgment of the Initial Purchasers based upon advice of
         counsel (which may be in-house counsel), represent the prevailing views
         of the staff of the Commission; and (v) in the case of a Shelf
         Registration Statement, include the names of the Holders who propose to
         sell Securities pursuant to the Shelf Registration Statement as selling
         securityholders.

                                       5

                  (b) The Company shall give written notice to the Initial
         Purchasers, the Holders of the Securities and any Participating
         Broker-Dealer from whom the Company has received prior written notice
         that it will be a Participating Broker-Dealer in the Registered
         Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall
         be accompanied by an instruction to suspend the use of the prospectus
         until the requisite changes have been made):

                           (i) when the Registration Statement or any amendment
                  thereto has been filed with the Commission and when the
                  Registration Statement or any post-effective amendment thereto
                  has become effective;

                           (ii) of any request by the Commission for amendments
                  or supplements to the Registration Statement or the prospectus
                  included therein or for additional information;

                           (iii) of the issuance by the Commission of any stop
                  order suspending the effectiveness of the Registration
                  Statement or the initiation of any proceedings for that
                  purpose;

                           (iv) of the receipt by the Company or its legal
                  counsel of any notification with respect to the suspension of
                  the qualification of the Securities for sale in any
                  jurisdiction or the initiation or threatening of any
                  proceeding for such purpose of which the Company has
                  knowledge; and

                           (v) of the happening of any event that requires the
                  Company to make changes in the Registration Statement or the
                  prospectus in order that the Registration Statement or the
                  prospectus do not contain an untrue statement of a material
                  fact nor omit to state a material fact required to be stated
                  therein or necessary to make the statements therein (in the
                  case of the prospectus, in light of the circumstances under
                  which they were made) not misleading.

                  (c) The Company shall make every reasonable effort to obtain
         the withdrawal, at the earliest possible time, of any order suspending
         the effectiveness of the Registration Statement.

                  (d) The Company shall furnish to each Holder of Securities
         included within the coverage of the Shelf Registration, without charge,
         at least one copy of the Shelf Registration Statement and any
         post-effective amendment thereto, including financial statements and
         schedules, and, if the Holder so requests in writing, all exhibits
         thereto (including those, if any, incorporated by reference).

                  (e) The Company shall deliver to each Exchanging Dealer and
         each Initial Purchaser, and to any other Holder who so requests,
         without charge, at least one copy of the Exchange Offer Registration
         Statement and any post-effective amendment thereto, including financial
         statements and schedules, and, if any Initial Purchaser or any such
         Holder requests, all exhibits thereto (including those incorporated by
         reference).

                  (f) The Company shall, during the Shelf Registration Period,
         deliver to each Holder of Securities included within the coverage of
         the Shelf Registration, without charge, as many copies of the
         prospectus (including each preliminary prospectus) included in the
         Shelf Registration Statement and any amendment or supplement thereto as
         such person may reasonably request. The Company consents, subject to
         the provisions of this Agreement, to the use in accordance with
         applicable law of the prospectus or any amendment or supplement thereto
         by each of the selling Holders of the Securities in connection with the
         offering and sale of the Securities covered by the prospectus, or any
         amendment or supplement thereto, included in the Shelf Registration
         Statement.

                                       6

                  (g) The Company shall deliver to each Initial Purchaser, any
         Exchanging Dealer, any Participating Broker-Dealer and such other
         persons required to deliver a prospectus following the Registered
         Exchange Offer, without charge, as many copies of the final prospectus
         included in the Exchange Offer Registration Statement and any amendment
         or supplement thereto as such persons may reasonably request. The
         Company consents, subject to the provisions of this Agreement, to the
         use in accordance with applicable law of the prospectus or any
         amendment or supplement thereto by any Initial Purchaser, if necessary,
         any Participating Broker-Dealer and such other persons required to
         deliver a prospectus following the Registered Exchange Offer in
         connection with the offering and sale of the Exchange Securities
         covered by the prospectus, or any amendment or supplement thereto,
         included in such Exchange Offer Registration Statement.

                  (h) Prior to any public offering of the Securities pursuant to
         any Registration Statement, the Company shall cooperate with the
         Holders of the Securities included therein and their Special Counsel
         (as defined in paragraph (p) below) in connection with the registration
         or qualification of the Securities for offer and sale under the
         securities or "blue sky" laws of such states of the United States as
         any Holder of the Securities reasonably requests in writing and do any
         and all other acts or things reasonably necessary or advisable to
         enable the offer and sale in such jurisdictions of the Securities
         covered by such Registration Statement; provided, however, that the
         Company shall not be required to (i) qualify generally to do business
         in any jurisdiction where it is not then so qualified or (ii) take any
         action which would subject it to general service of process or to
         taxation in any jurisdiction where it is not then so subject.

                  (i) The Company shall cooperate with the Holders of the
         Securities to facilitate the timely preparation and delivery of
         certificates representing the Securities to be sold pursuant to any
         Registration Statement free of any restrictive legends and in such
         denominations and registered in such names as the Holders may request a
         reasonable period of time prior to sales of the Securities pursuant to
         such Registration Statement.

                  (j) Upon the occurrence of any event contemplated by
         paragraphs (ii) through (v) of Section 3(b) above during the period for
         which the Company is required to maintain an effective Registration
         Statement, the Company shall promptly prepare and file a post-effective
         amendment to the Registration Statement or a supplement to the related
         prospectus and any other required document so that, as thereafter
         delivered to Holders of the Securities or purchasers of Securities, the
         prospectus will not contain an untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading. If the Company notifies the
         Initial Purchasers, the Holders of the Securities and any known
         Participating Broker-Dealer in accordance with paragraphs (ii) through
         (v) of Section 3(b) above to suspend the use of the prospectus until
         the requisite changes to the prospectus have been made, then the
         Initial Purchasers, the Holders of the Securities and any such
         Participating Broker-Dealers shall suspend use of such prospectus, and
         the period of effectiveness of the Shelf Registration Statement
         provided for in Section 2(b) above and the Exchange Offer Registration
         Statement provided for in Section 1 above shall each be extended by the
         number of days from and including the date of the giving of such notice
         to and including the date when the Initial Purchasers, the Holders of
         the Securities and any known Participating Broker-Dealer shall have
         received such amended or supplemented prospectus pursuant to this
         Section 3(j).

                  (k) Not later than the effective date of the applicable
         Registration Statement, the Company will provide a CUSIP number for the
         Initial Securities, the Exchange Securities or the Private Exchange
         Securities, as the case may be, and provide the applicable trustee with
         printed certificates for the Initial Securities, the Exchange
         Securities or the Private Exchange Securities, as the case may be, in a
         form eligible for deposit with The Depository Trust Company.

                                       7

                  (l) The Company will use its reasonable best efforts to comply
         with all rules and regulations of the Commission to the extent and so
         long as they are applicable to the Registered Exchange Offer or the
         Shelf Registration and will make generally available to its security
         holders (or otherwise provide in accordance with Section 11(a) of the
         Securities Act) an earnings statement satisfying the provisions of
         Section 11(a) of the Securities Act, no later than 45 days after the
         end of a 12-month period (or 90 days, if such period is a fiscal year)
         beginning with the first month of the Company's first fiscal quarter
         commencing after the effective date of the Registration Statement,
         which statement shall cover such 12-month period.

                  (m) The Company shall use its reasonable best efforts to cause
         the Indenture to be qualified under the Trust Indenture Act of 1939, as
         amended, in a timely manner and, in connection therewith, cooperate
         with the Trustee under the Indenture and the Holders of Securities to
         effect such changes to the Indenture as may be required for such
         qualification. In the event that such qualification would require the
         appointment of a new trustee under the Indenture, the Company shall
         appoint a new trustee thereunder pursuant to the applicable provisions
         of the Indenture.

                  (n) The Company may require each Holder of Securities to be
         sold pursuant to the Shelf Registration Statement to furnish to the
         Company such information regarding the Holder and the distribution of
         the Securities as the Company may from time to time reasonably require
         for inclusion in the Shelf Registration Statement, and the Company may
         exclude from such registration the Securities of any Holder that fails
         to furnish such information within a reasonable time after receiving
         such request.

                  (o) The Company shall enter into such customary agreements
         (including, if requested, an underwriting agreement in customary form)
         and take all such other action, if any, as any Holder of the Securities
         shall reasonably request in order to facilitate the disposition of the
         Securities pursuant to any Shelf Registration.

                  (p) In the case of any Shelf Registration, the Company shall
         (i) make available at reasonable times and upon reasonable notice for
         inspection by a representative of the Holders of a majority in
         aggregate principal amount of the Securities being sold, any
         underwriter participating in any disposition pursuant to the Shelf
         Registration Statement and any attorney, accountant or other agent
         retained by the Holders of the Securities or any such underwriter all
         relevant financial and other records, pertinent corporate documents and
         properties of the Company and (ii) cause the Company's officers,
         directors, employees, accountants and auditors to supply all relevant
         information reasonably requested by the Holders of the Securities or
         any such underwriter, attorney, accountant or agent in connection with
         the Shelf Registration Statement, in each case, as shall be reasonably
         necessary to enable such persons to conduct a reasonable investigation
         within the meaning of Section 11 of the Securities Act; provided,
         however, that the foregoing inspection and information gathering shall
         be coordinated on behalf of the Initial Purchasers by you and on behalf
         of the other parties, by one counsel designated by and on behalf of
         such other parties as described herein (which counsel shall be Latham &
         Watkins LLP or another law firm reasonably acceptable to the Company,
         such counsel being referred to herein as the "SPECIAL COUNSEL");
         provided, further, however, that, as a condition to supplying such
         information, the Company shall receive an agreement in writing from
         such Special Counsel agreeing that any information that is designated
         in writing by the Company, in good faith, as confidential at the time
         of delivery of such information shall be kept confidential by such
         Special Counsel and any other person entitled to receive such
         information pursuant to this paragraph (p) unless (w) disclosure of
         such information is required pursuant to applicable law or by court or
         administrative order, (x) disclosure of such information is, in the
         reasonable opinion of counsel to the Company, necessary to avoid or
         correct a misstatement or omission of a material fact in any
         Registration Statement, prospectus or any

                                       8

         supplement or post-effective amendment thereto or disclosure is
         otherwise required by law, (y) such information becomes generally
         available to the public other than as a result of a disclosure by such
         counsel or any other person entitled to receive such information
         pursuant to this paragraph (p) in violation of this proviso or (z) such
         information is approved for release by the Company in writing.

                  (q) In the case of any Shelf Registration, the Company, if
         requested by any Holder of Securities covered thereby, shall cause (i)
         its counsel to deliver an opinion and updates thereof relating to the
         Securities in customary form addressed to such Holders and the managing
         underwriters, if any, thereof and dated, in the case of the initial
         opinion, the effective date of such Shelf Registration Statement (it
         being agreed that the matters to be covered by such opinion shall
         include, without limitation, the due incorporation and good standing of
         the Company and its "significant subsidiaries" (as defined in Rule
         1-02(w) of Regulation S-X); the qualification of the Company and its
         significant subsidiaries to transact business as foreign corporations;
         the due authorization, execution and delivery of the relevant agreement
         of the type referred to in Section 3(o) hereof; the due authorization,
         execution, authentication and issuance, and the validity and
         enforceability, of the applicable Securities; the absence of material
         legal or governmental proceedings involving the Company and its
         significant subsidiaries; the absence of governmental approvals
         required to be obtained in connection with the Shelf Registration
         Statement, the offering and sale of the applicable Securities, or any
         agreement of the type referred to in Section 3(o) hereof; the
         compliance as to form of such Shelf Registration Statement and any
         documents incorporated by reference therein and of the Indenture with
         the requirements of the Securities Act and the Trust Indenture Act,
         respectively; and, as of the date of the opinion and as of the
         effective date of the Shelf Registration Statement or most recent
         post-effective amendment thereto, as the case may be, the absence from
         such Shelf Registration Statement and the prospectus included therein,
         as then amended or supplemented, and from any documents incorporated by
         reference therein, if applicable, of an untrue statement of a material
         fact or the omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading (in the case of any such documents, in the light of the
         circumstances existing at the time that such documents were filed with
         the Commission under the Exchange Act); (ii) its officers to execute
         and deliver all customary documents and certificates and updates
         thereof requested by any underwriters of the applicable Securities; and
         (iii) its independent public accountants and the independent public
         accountants with respect to any other entity, if any, for which
         financial information is provided in the Shelf Registration Statement
         to provide to the selling Holders of the applicable Securities and any
         underwriter therefor a comfort letter in customary form and covering
         matters of the type customarily covered in comfort letters in
         connection with underwritten offerings, subject to receipt of
         appropriate documentation as contemplated, and only if permitted, by
         Statement of Auditing Standards No. 72.

                  (r) In the case of the Registered Exchange Offer, if requested
         by any Initial Purchaser or any known Participating Broker-Dealer, the
         Company shall cause (i) its counsel to deliver to such Initial
         Purchaser or such Participating Broker-Dealer a signed opinion in the
         form set forth in Section 6(c)-(e) of the Purchase Agreement with such
         changes as are customary in connection with the preparation of a
         Registration Statement and (ii) its independent public accountants and
         the independent public accountants with respect to any other entity, if
         any, for which financial information is provided in the Registration
         Statement to deliver to such Initial Purchaser or such Participating
         Broker-Dealer a comfort letter, in customary form, meeting the
         requirements as to the substance thereof as set forth in Section 6(a)
         of the Purchase Agreement, with appropriate date changes.

                  (s) If a Registered Exchange Offer or a Private Exchange is to
         be consummated, upon delivery of the Initial Securities by Holders to
         the Company (or to such other Person as directed by the Company) in
         exchange for the Exchange Securities or the Private Exchange
         Securities, as the

                                       9

         case may be, the Company shall mark, or caused to be marked, on the
         Initial Securities so exchanged that such Initial Securities are being
         canceled in exchange for the Exchange Securities or the Private
         Exchange Securities, as the case may be; in no event shall the Initial
         Securities be marked as paid or otherwise satisfied.

                  (t) The Company will use its reasonable best efforts to cause
         the Securities covered by any Registration Statement to continue to be
         rated by the rating agencies that initially rated the Securities during
         the period that any such Registration Statement is required hereunder
         to remain effective (it being acknowledged, however, that the foregoing
         shall not be deemed to require the Company to maintain the rating of
         such Securities at the rating initially given to the Securities).

                  (u) In the event that any broker-dealer registered under the
         Exchange Act shall underwrite any Securities or participate as a member
         of an underwriting syndicate or selling group or "assist in the
         distribution" (within the meaning of the Conduct Rules (the "RULES") of
         the National Association of Securities Dealers, Inc. ("NASD")) thereof,
         whether as a Holder of such Securities or as an underwriter, a
         placement or sales agent or a broker or dealer in respect thereof, or
         otherwise, the Company will assist such broker-dealer in complying with
         the requirements of such Rules, including, without limitation, by (i)
         if such Rules, including Rule 2720, shall so require, engaging a
         "qualified independent underwriter" (as defined in Rule 2720) to
         participate in the preparation of the Registration Statement relating
         to such Securities, to exercise usual standards of due diligence in
         respect thereto and, if any portion of the offering contemplated by
         such Registration Statement is an underwritten offering or is made
         through a placement or sales agent, to recommend the yield of such
         Securities, (ii) indemnifying any such qualified independent
         underwriter to the extent of the indemnification of underwriters
         provided in Section 5 hereof and (iii) providing such information to
         such broker-dealer as may be required in order for such broker-dealer
         to comply with the requirements of the Rules.

                  (v) The Company shall use its reasonable best efforts to take
         all other steps necessary to effect the registration of the Securities
         covered by a Registration Statement contemplated hereby.

                  (w) Notwithstanding any other provision hereof, the Company
         may postpone or suspend the filing or the effectiveness of a
         Registration Statement (or any amendments or supplements thereto) if
         (i) such action is required by applicable law or (ii) such action is
         taken by the Company in good faith and for valid business reasons (not
         including the avoidance of the Company's obligations hereunder),
         including the acquisition or divestiture of assets, other pending
         corporate developments, public filings with the Commission or other
         similar events, so long as the Company promptly thereafter complies
         with the requirements of Section 3(j) hereof, if applicable.
         Notwithstanding the occurrence of any event referred to in the
         immediately preceding sentence (each such occurrence, a "SUSPENSION"),
         no such Suspension shall suspend, postpone or in any other manner
         affect the running of the time period after which a Registration
         Default shall be deemed to occur and, if the filing or effectiveness of
         any such Registration Statement is postponed or suspended as a result
         of a Suspension, a Registration Default shall nonetheless exist if all
         other requirements required for the occurrence of a Registration
         Default shall then be satisfied, and the provisions of Section 6 hereof
         requiring the accrual and payment of Additional Interest, as set forth
         in such Section, on the Securities shall be payable.

         4.  Registration Expenses.

                   (a) All expenses incident to the Company's performance of and
         compliance with this Agreement will be borne by the Company, regardless
         of whether a Registration Statement is ever filed or becomes effective,
         including without limitation;

                           (i)  all registration and filing fees and expenses;

                                       10

                           (ii) all fees and expenses of compliance with federal
                  securities and state "blue sky" or securities laws;

                           (iii) all expenses of printing (including printing
                  certificates for the Securities to be issued in the Registered
                  Exchange Offer and the Private Exchange and printing of
                  Prospectuses), messenger and delivery services and telephone;

                           (iv) all fees and disbursements of counsel for the
                  Company; and

                           (v) all fees and disbursements of independent
                  certified public accountants of the Company (including the
                  expenses of any special audit and comfort letters required by
                  or incident to such performance).

         The Company will bear its internal expenses (including, without
         limitation, all salaries and expenses of its officers and employees
         performing legal or accounting duties), the expenses of any annual
         audit and the fees and expenses of any person, including special
         experts, retained by the Company.

                  (b) In connection with any Registration Statement required by
         this Agreement, the Company will reimburse the Initial Purchasers and
         the Holders of Transfer Restricted Securities who are tendering Initial
         Securities in the Registered Exchange Offer and/or selling or reselling
         Securities pursuant to the "Plan of Distribution" contained in the
         Exchange Offer Registration Statement or the Shelf Registration
         Statement, as applicable, for the reasonable fees and disbursements of
         the Special Counsel.

         5.  Indemnification.

                  (a) The Company agrees to indemnify and hold harmless each
         Holder of the Securities, any Participating Broker-Dealer and each
         person, if any, who controls such Holder or such Participating
         Broker-Dealer within the meaning of the Securities Act or the Exchange
         Act (each Holder, any Participating Broker-Dealer and such controlling
         persons are referred to collectively as the "Indemnified PARTIES") from
         and against any losses, claims, damages or liabilities, joint or
         several, or any actions in respect thereof (including, but not limited
         to, any losses, claims, damages, liabilities or actions relating to
         purchases and sales of the Securities) to which each Indemnified Party
         may become subject under the Securities Act, the Exchange Act or
         otherwise, insofar as such losses, claims, damages, liabilities or
         actions arise out of or are based upon any untrue statement or alleged
         untrue statement of a material fact contained in a Registration
         Statement or prospectus or in any amendment or supplement thereto or in
         any preliminary prospectus relating to a Shelf Registration, or arise
         out of, or are based upon, the omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading, and shall reimburse, as
         incurred, the Indemnified Parties for any legal or other expenses
         reasonably incurred by them in connection with investigating or
         defending any such loss, claim, damage, liability or action in respect
         thereof; provided, however, that (i) the Company shall not be liable in
         any such case to the extent that such loss, claim, damage or liability
         arises out of or is based upon any untrue statement or alleged untrue
         statement or omission or alleged omission made in a Registration
         Statement or prospectus or in any amendment or supplement thereto or in
         any preliminary prospectus relating to a Shelf Registration in reliance
         upon and in conformity with written information pertaining to such
         Holder and furnished to the Company by or on behalf of such Holder
         specifically for inclusion therein and (ii) with respect to any untrue
         statement or omission or alleged untrue statement or omission made in
         any preliminary prospectus relating to a Shelf Registration Statement,
         the indemnity agreement contained in this subsection (a) shall not
         inure to the benefit of any Holder or Participating Broker-Dealer from

                                       11

         whom the person asserting any such losses, claims, damages or
         liabilities purchased the Securities concerned, to the extent that a
         prospectus relating to such Securities was required to be delivered by
         such Holder or Participating Broker-Dealer under the Securities Act in
         connection with such purchase and any such loss, claim, damage or
         liability of such Holder or Participating Broker-Dealer results from
         the fact that there was not sent or given to such person, at or prior
         to the written confirmation of the sale of such Securities to such
         person, a copy of the final prospectus if the Company had previously
         furnished copies thereof to such Holder or Participating Broker-Dealer;
         provided further, however, that this indemnity agreement will be in
         addition to any liability which the Company may otherwise have to such
         Indemnified Party. The Company shall also indemnify underwriters, their
         officers and directors and each person who controls such underwriters
         within the meaning of the Securities Act or the Exchange Act to the
         same extent as provided above with respect to the indemnification of
         the Holders of the Securities if requested by such Holders.

                  (b) Each Holder of the Securities, severally and not jointly,
         will indemnify and hold harmless the Company and each person, if any,
         who controls the Company within the meaning of the Securities Act or
         the Exchange Act from and against any losses, claims, damages or
         liabilities or any actions in respect thereof, to which the Company or
         any such controlling person may become subject under the Securities
         Act, the Exchange Act or otherwise, insofar as such losses, claims,
         damages, liabilities or actions arise out of or are based upon any
         untrue statement or alleged untrue statement of a material fact
         contained in a Registration Statement or prospectus or in any amendment
         or supplement thereto or in any preliminary prospectus relating to a
         Shelf Registration, or arise out of or are based upon the omission or
         alleged omission to state therein a material fact necessary to make the
         statements therein not misleading, but in each case only to the extent
         that the untrue statement or omission or alleged untrue statement or
         omission was made in reliance upon and in conformity with written
         information pertaining to such Holder and furnished to the Company by
         or on behalf of such Holder specifically for inclusion therein; and,
         subject to the limitation set forth immediately preceding this clause,
         shall reimburse, as incurred, the Company for any legal or other
         expenses reasonably incurred by the Company or any such controlling
         person in connection with investigating or defending any loss, claim,
         damage, liability or action in respect thereof. This indemnity
         agreement will be in addition to any liability which such Holder may
         otherwise have to the Company or any of its controlling persons.

                  (c) Promptly after receipt by an indemnified party under this
         Section 5 of notice of the commencement of any action or proceeding
         (including a governmental investigation), such indemnified party will,
         if a claim in respect thereof is to be made against the indemnifying
         party under this Section 5, notify the indemnifying party of the
         commencement thereof; provided, however, that the omission so to notify
         the indemnifying party (i) shall not relieve the indemnifying party
         from any obligations to any indemnified party other than the
         indemnification obligation provided in paragraph (a) or (b) above. In
         case any such action is brought against any indemnified party, and it
         notifies the indemnifying party of the commencement thereof, the
         indemnifying party will be entitled to participate therein and, to the
         extent that it may wish, jointly with any other indemnifying party
         similarly notified, to assume the defense thereof, with counsel
         reasonably satisfactory to such indemnified party (who shall not,
         except with the consent of the indemnified party, be counsel to the
         indemnifying party), and after notice from the indemnifying party to
         such indemnified party of its election so to assume the defense thereof
         the indemnifying party will not be liable to such indemnified party
         under this Section 5 for any legal or other expenses, other than
         reasonable costs of investigation, subsequently incurred by such
         indemnified party in connection with the defense thereof; provided,
         however, that the indemnified party shall have the right to employ
         counsel to represent the indemnified party and their respective
         controlling persons who may be subject to liability arising out of any
         claim in respect of which indemnity may be sought by the indemnified
         party against the indemnifying party under this Section 5 if the
         employment of such counsel shall have been authorized in writing by the
         indemnifying party in

                                       12

         connection with the defense of such action, if in the written opinion
         of counsel to either the indemnifying party or the indemnified party,
         representation of both parties by the same counsel would be
         inappropriate due to actual or likely conflicts of interest between
         them or the indemnifying party shall have failed to employ counsel
         within a reasonable period of time, and in that event the fees and
         expenses of one firm of separate counsel (in addition to the fees and
         expenses of one firm of local counsel in each applicable jurisdiction)
         shall be paid by the indemnifying party. No indemnifying party shall,
         without the prior written consent of the indemnified party, effect any
         settlement of any pending or threatened action in respect of which any
         indemnified party is or could have been a party and indemnity could
         have been sought hereunder by such indemnified party unless such
         settlement (i) includes an unconditional release of such indemnified
         party from all liability on any claims that are the subject matter of
         such action, and (ii) does not include a statement as to or an
         admission of fault, culpability or a failure to act by or on behalf of
         any indemnified party.

                  (d) If the indemnification provided for in this Section 5 is
         unavailable or insufficient to hold harmless an indemnified party under
         subsections (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities (or actions in
         respect thereof) referred to in subsection (a) or (b) above in such
         proportion as is appropriate to reflect the relative fault of the
         indemnifying party or parties on the one hand and the indemnified party
         on the other in connection with the statements or omissions that
         resulted in such losses, claims, damages or liabilities (or actions in
         respect thereof) as well as any other relevant equitable
         considerations. The relative fault of the parties shall be determined
         by reference to, among other things, whether the untrue or alleged
         untrue statement of a material fact or the omission or alleged omission
         to state a material fact relates to information supplied by the Company
         on the one hand or such Holder or such other indemnified party, as the
         case may be, on the other, and the parties' relative intent, knowledge,
         access to information and opportunity to correct or prevent such
         statement or omission. The amount paid by an indemnified party as a
         result of the losses, claims, damages or liabilities referred to in the
         first sentence of this subsection (d) shall be deemed to include any
         legal or other expenses reasonably incurred by such indemnified party
         in connection with investigating or defending any action or claim which
         is the subject of this subsection (d). Notwithstanding any other
         provision of this Section 5(d), the Holders of the Securities shall not
         be required to contribute any amount in excess of the amount by which
         the net proceeds received by such Holders from the sale of the
         Securities pursuant to a Registration Statement exceeds the amount of
         damages which such Holders have otherwise been required to pay by
         reason of such untrue or alleged untrue statement or omission or
         alleged omission. No person guilty of fraudulent misrepresentation
         (within the meaning of Section 11(f) of the Securities Act) shall be
         entitled to contribution from any person who was not guilty of such
         fraudulent misrepresentation. For purposes of this paragraph (d), each
         person, if any, who controls such indemnified party within the meaning
         of the Securities Act or the Exchange Act shall have the same rights to
         contribution as such indemnified party and each person, if any, who
         controls the Company within the meaning of the Securities Act or the
         Exchange Act shall have the same rights to contribution as the Company.

                  (e) The agreements contained in this Section 5 shall survive
         the sale of the Securities pursuant to a Registration Statement and
         shall remain in full force and effect, regardless of any termination or
         cancellation of this Agreement or any investigation made by or on
         behalf of any indemnified party.

         6.  Additional Interest Under Certain Circumstances.

                  (a) Additional interest (the "ADDITIONAL INTEREST") with
         respect to each Transfer Restricted Security shall be assessed as
         follows if either of the following events occur (each such event in
         clauses (i) and (ii) below being herein called an "REGISTRATION
         DEFAULT"):

                                       13

                           (i) any Registration Statement required by this
                  Agreement is not declared effective by the Commission on or
                  prior to the applicable Effectiveness Deadline; or

                           (ii) on and after the applicable Effectiveness
                  Deadline (plus an additional 30 days in respect of the
                  Exchange Offer Registration Statement), any Registration
                  Statement required by this Agreement has been declared
                  effective by the Commission but (A) such Registration
                  Statement thereafter ceases to be effective or (B) such
                  Registration Statement or the related prospectus ceases to be
                  usable in connection with resales of Transfer Restricted
                  Securities during the periods specified herein because (1) any
                  event occurs as a result of which the related prospectus
                  forming part of such Registration Statement would include any
                  untrue statement of a material fact or omit to state any
                  material fact necessary to make the statements therein in the
                  light of the circumstances under which they were made not
                  misleading, (2) it shall be necessary to amend such
                  Registration Statement or supplement the related prospectus to
                  comply with the Securities Act or the Exchange Act or the
                  respective rules thereunder or (3) of a Suspension by the
                  Company in accordance with Section 3(w) hereof.

         Each of the foregoing will constitute a Registration Default whatever
         the reason for any such event and whether it is voluntary or
         involuntary or is beyond the control of the Company or pursuant to
         operation of law or as a result of any action or inaction by the
         Commission .

         Additional Interest shall accrue on each Transfer Restricted Security
         over and above the interest set forth in the title of such Transfer
         Restricted Security from and including the date on which any such
         Registration Default shall occur to but excluding the date on which all
         such Registration Defaults have ceased to be continuing, at a rate of
         0.50% per annum (the "ADDITIONAL INTEREST RATE").

                  (b) A Registration Default referred to in Section 6(a)(ii)
         hereof shall be deemed not to have occurred and be continuing in
         relation to a Shelf Registration Statement or the related prospectus if
         (i) such Registration Default has occurred solely as a result of (x)
         the filing of a post-effective amendment to such Shelf Registration
         Statement to incorporate annual audited financial information with
         respect to the Company where such post-effective amendment is not yet
         effective and needs to be declared effective to permit Holders to use
         the related prospectus or (y) other material events with respect to the
         Company that would need to be described in such Shelf Registration
         Statement or the related prospectus and (ii) in the case of clause (y),
         the Company is proceeding promptly and in good faith to amend or
         supplement such Shelf Registration Statement and related prospectus to
         describe such events; provided, however, that in any case if such
         Registration Default occurs for a continuous period in excess of 30
         days, Additional Interest shall be payable in accordance with the above
         paragraph from the date of such Registration Default until such
         Registration Default ceases.

                  (c) Notwithstanding the foregoing, the Company shall not be
         required to pay the Additional Interest required pursuant to paragraph
         (a) above to a Holder of Transfer Restricted Securities if the
         applicable Registration Default arises by reason of the failure of such
         Holder to provide such information as (i) the Company may reasonably
         request, with reasonable prior written notice, for use in the Shelf
         Registration Statement or any prospectus included therein to the extent
         the Company reasonably determines that such information is required to
         be included therein by applicable law, (ii) the NASD or the Commission
         may request in connection with such Shelf Registration Statement or
         (iii) is required to comply with the agreements of such Holder
         contained in Section 3(a) to the extent compliance thereof is necessary
         for the Shelf Registration Statement to be declared effective.

                                       14

                  (d) Any amounts of Additional Interest due pursuant to Section
         6(a) will be payable in cash on the regular interest payment dates with
         respect to the Securities. The amount of Additional Interest will be
         determined by multiplying the applicable Additional Interest Rate by
         the principal amount of the Securities and further multiplied by a
         fraction, the numerator of which is the number of days such Additional
         Interest Rate was applicable during such period (determined on the
         basis of a 360-day year comprised of twelve 30-day months), and the
         denominator of which is 360.

                  (e) "TRANSFER RESTRICTED SECURITIES" means each Security until
         (i) the date on which such Security has been exchanged by a person
         other than a broker-dealer for a freely transferable Exchange Security
         in the Registered Exchange Offer, (ii) following the exchange by a
         broker-dealer in the Registered Exchange Offer of an Initial Security
         for an Exchange Security, the date on which such Exchange Security is
         sold to a purchaser who receives from such broker-dealer on or prior to
         the date of such sale a copy of the prospectus contained in the
         Exchange Offer Registration Statement, (iii) the date on which such
         Security has been effectively registered under the Securities Act and
         disposed of in accordance with the Shelf Registration Statement or (iv)
         the date on which such Security is distributed to the public pursuant
         to Rule 144 under the Securities Act or is saleable pursuant to Rule
         144(k) under the Securities Act.

         7. Rules 144 and 144A. The Company agrees with each Holder, for so long
as any Transfer Restricted Securities remain outstanding and during any period
in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange
Act, to make available, upon request of any Holder, to such Holder or beneficial
owner of Transfer Restricted Securities in connection with any sale thereof and
any prospective purchaser of such Transfer Restricted Securities designated by
such Holder or beneficial owner, the information required by Rule 144A(d)(4)
under the Securities Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

         8. Underwritten Registrations. If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an underwritten
offering, subject to the proviso in Section 3(o) hereof, the investment banker
or investment bankers and manager or managers that will administer the offering
("MANAGING UNDERWRITERS") will be selected by the Holders of a majority in
aggregate principal amount of such Transfer Restricted Securities to be included
in such offering and will be reasonably acceptable to the Company.

         No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

         9.  Miscellaneous.

                  (a) Remedies. The Company acknowledges and agrees that any
         failure by the Company to comply with its obligations under Section 1
         and 2 hereof may result in material irreparable injury to the Initial
         Purchasers or the Holders for which there is no adequate remedy at law,
         that it will not be possible to measure damages for such injuries
         precisely and that, in the event of any such failure, the Initial
         Purchasers or any Holder may obtain such relief as may be required to
         specifically enforce the Company's obligations under Sections 1 and 2
         hereof. The Company further agrees to waive the defense in any action
         for specific performance that a remedy at law would be adequate.

                                       15

                  (b) No Inconsistent Agreements. The Company will not on or
         after the date of this Agreement enter into any agreement with respect
         to its securities that is inconsistent with the rights granted to the
         Holders in this Agreement or otherwise conflicts with the provisions
         hereof. The Company hereby represents that the rights granted to the
         Holders hereunder do not conflict with and are not inconsistent with
         the rights granted to the holders of the Company's securities under any
         agreement in effect on the date hereof.

                  (c) Amendments and Waivers. The provisions of this Agreement
         may not be amended, modified or supplemented, and waivers or consents
         to departures from the provisions hereof may not be given, except by
         the Company and the written consent of the Holders of a majority in
         principal amount of the Securities affected by such amendment,
         modification, supplement, waiver or consents; provided, however, that,
         with respect to any matter that directly or indirectly adversely
         affects the rights of any Holder of Transfer Restricted Securities
         occurring within the period in which any Registration Statement is
         effective for such Holder, the Company shall obtain the written consent
         of each such Holder against which such amendment, modification,
         supplement, waiver, consent or departure is to be effective.
         Notwithstanding the foregoing (except of the foregoing proviso), a
         waiver or consent to departure from the provisions hereof with respect
         to a matter that relates exclusively to the rights of any Holder of
         Securities whose Securities are being sold or exchanged pursuant to a
         Registration Statement and that does not directly or indirectly
         adversely affect the rights of any other Holder of Securities may be
         given by Holders of at least a majority in aggregate principal amount
         of the Securities being sold or exchanged by such holders pursuant to
         such Registration Statement; provided, however, that the provisions of
         this sentence may not be amended, modified or supplemented except in
         accordance with the provisions of the immediately preceding sentence.
         Without the consent of the Holder of each Security, however, no
         modification may change the provisions relating to the payment of
         Additional Interest.

         Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. The Letter
of Transmittal states that 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. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Securities received in exchange for Initial Securities
where such Initial Securities were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 120 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution."

                                                                         ANNEX B

         Each broker-dealer that receives Exchange Securities for its own
account in exchange for Initial Securities, where such Initial Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Securities. See "Plan of
Distribution."

                                                                         ANNEX C

                              PLAN OF DISTRIBUTION

         Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that, for a period of 120 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale. In addition, until              , 200  ,
all dealers effecting transactions in the Exchange Securities may be required to
deliver a prospectus.(1)

         The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver 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.

         For a period of 120 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
