<PAGE>

COMPANY. THE SECURITY AGREEMENT SETS FORTH VARIOUS PROVISIONS REGARDING (AMONG

RESPECT TO THIS BOND. THE SECURITY AGREEMENT MAY IMPOSE LIMITATIONS ON THE
AMOUNTS PAYABLE UNDER THIS BOND. THE COMPANY AND (BY THEIR ACCEPTANCE THEREOF)
EACH HOLDER OF THIS BOND AGREE THAT THE RIGHTS OF THE PARTIES WITH RESPECT TO

PROVISIONS OF THE SECURITY AGREEMENT.

         NORTHERN STATES POWER COMPANY, a corporation organized and existing
under the laws of the State of Minnesota (the "Company"), for value received,
hereby promises to pay the sum of ______________________ Dollars ($_________),
subject to reductions of principal and limitations on payment as and to the
extent set forth in the Security Agreement (as defined below), to Wells Fargo
Bank, National Association, as Administrative Agent (the "Administrative
Agent"), on behalf of itself and the Banks (as defined below), or registered
assigns, at the office of the Trustee in Chicago, Illinois, or, at the option of
the registered owner, at the agency of the Company in the Borough of Manhattan,
City and State of New York, on May 14, 2004 (the "Maturity Date") or upon
earlier declaration of acceleration or redemption; provided, however, that, in
the event the Commitment Termination Date, under and as defined in the Credit
Agreement (as defined below), is extended in accordance with the terms of the
Credit Agreement, the Maturity Date shall be automatically extended to the date
of such extended Commitment Termination Date and the principal amount of the
bonds of this series shall be automatically reduced to the extent of the
reductions to the Commitment Amounts (as defined in the Credit Agreement), if
any, made in accordance with the Credit Agreement without any further act on the
part of the Company or the holders of the bonds of this series; provided,
further, that the Maturity Date as so extended shall in no event be later than
May 12, 2006 (the Maturity Date or, if extended, the date to which the Maturity
Date shall be extended in accordance with the terms hereof, shall be referred to
as the "Stated Maturity Date"). This bond shall not bear interest. Payment of
the principal on this bond shall be made in the lawful money of the United
States.

         This bond is issued to the Administrative Agent by the Company pursuant
to the Company's obligations under the Credit Agreement dated as of May 16, 2003
(as amended, supplemented, restated, extended or otherwise modified from time to
time, the "Credit Agreement"), among the Company, the Administrative Agent, and
the other banks party thereto from time to time (collectively, the "Banks"),
including any amendments or extensions thereto that may be subsequent to the
date hereof. This bond shall be held by the Administrative Agent subject to the
terms of the Credit Agreement and the Security Agreement dated as of May 16,
2003 between the Company and the Administrative Agent (the "Security
Agreement").

         It shall be an additional term and condition of the bonds of this
series that, in the event (i) an Event of Default under and as defined in the
Credit Agreement has occurred under Section 7.1(a) of the Credit Agreement by
reason of a failure by the Company to make a payment of principal when the same
shall be due and payable pursuant to the Credit Agreement or (ii) the Notes (as
defined in the Credit Agreement) are declared due and payable pursuant to
Section 7.2 of the Credit Agreement, then the occurrence of either such event
shall be deemed, upon written notice from the Administrative Agent to the
Trustee of the occurrence thereof, to be

                                       5
<PAGE>

a completed default, for purposes of Section 1(a) of Article XIII of the
Original Indenture prior to the Effective Date (as defined below), and a
Completed Default, for purposes of Section 13.01(a) of the Indenture on and
after the Effective Date, and the definitions of completed default and Completed
Default in the Original Indenture and the Indenture, respectively, are modified
accordingly for purposes of the bonds of this series.

         The Trustee may conclusively presume that the obligation of the Company
to pay the principal of this bond shall have been fully satisfied and discharged
unless and until it shall have received a written notice from the Administrative
Agent, signed by an authorized officer of the Administrative Agent and attested
by the Secretary or an Assistant Secretary of the Administrative Agent, stating
that the payment of principal of this bond has not been fully paid when due and
specifying the amount of funds required to make such payment.

         This bond has been issued by the Company to the Administrative Agent to
(i) provide for the payment of the Company's obligations to make payments to any
person under the Credit Agreement and (ii) provide to such persons the benefits
of the security provided for this bond pursuant to the Indenture. The
obligations of the Company under the bonds of this series may be discharged
prior to the Stated Maturity Date under the circumstances set forth in the
Security Agreement.

         This bond is one of a duly authorized issue of bonds of the Company, of
the series and designation indicated on the face hereof, which issue of bonds
consists, or may consist, of several series of varying denominations, dates, and
tenor, all issued and to be issued under and equally secured (except insofar as
a sinking fund, or similar fund, established in accordance with the provisions
of the Indenture may afford additional security for the bonds of any specific
series) by a Trust Indenture dated February 1, 1937 (the "1937 Indenture"), as
supplemented by 52 supplemental trust indentures (collectively, the
"Supplemental Indentures" and together with the 1937 Indenture, the "Original
Indenture"), a Supplemental and Restated Trust Indenture dated May 1, 1988 (the
"Restated Indenture") and a new supplemental trust indenture for the bonds of
this series (the "New Supplemental Indenture"), executed by the Company to BNY
Midwest Trust Company, as successor to Harris Trust and Savings Bank, as Trustee
(the "Trustee"). The 1937 Indenture, as supplemented by the Supplemental
Indentures, the Restated Indenture and the New Supplemental Indenture herein are
referred to collectively as the "Indenture". Reference hereby is made to the
Indenture for a description of the property mortgaged and pledged, the nature
and extent of the security, the rights of the holders of the bonds as to such
security, and the terms and conditions upon which the bonds may be issued under
the Indenture and are secured. The principal hereof may be declared or may
become due on the conditions, in the manner and at the time set forth in the
Indenture, upon the happening of a default as in the Indenture, including the
New Supplemental Indenture, provided.

         The rights of the holder of this bond to vote or consent under the
Indenture in respect of this bond shall be limited to the extent and in the
manner specified in the Security Agreement. With the consent of the Company and
to the extent permitted by and as provided in the Indenture, the rights and
obligations of the Company and of the holders of the bonds, and the terms and
provisions of the Indenture and of any instruments supplemental thereto may be
modified or altered by affirmative vote of the holders of at least 80% in
principal amount of the bonds then outstanding under the Indenture and any
instruments supplemental thereto (excluding

                                       6
<PAGE>

bonds challenged and disqualified from voting by reason of the Company's
interest therein as provided in the Indenture); provided that without the
consent of all holders of all bonds affected no such modification or alteration
shall permit the extension of the maturity of the principal of any bond or the
reduction in the rate of interest thereon or any other modification in the terms
of payment of such principal or interest. The foregoing 80% requirement will be
reduced to 66 2/3% when all bonds of each series issued under the Indenture
prior to May 1, 1985, shall have been retired or all the holders thereof shall
have consented to such reduction.

         The Restated Indenture amends and restates the 1937 Indenture and the
Supplemental Indentures. The Restated Indenture will become effective and
operative (the "Effective Date") when all bonds of each series issued under the
Indenture prior to May 1, 1988 shall have been retired through payment or
redemption (including those bonds "deemed to be paid" within the meaning of that
term as used in Article XVII of the 1937 Indenture) or until, subject to certain
exceptions, the holders of the requisite principal amount of such bonds shall
have consented to the amendments contained in the Restated Indenture. Holders of
the bonds of this series and of each subsequent series of bonds issued under the
Indenture likewise will be bound by the amendments contained in the Restated
Indenture when they become effective and operative. Reference is made to the
Restated Indenture for a complete description of the amendments contained
therein to the 1937 Indenture and to the Supplemental Indentures.

         The Company and the Trustee may deem and treat the person in whose name
this bond is registered as the absolute owner hereof for the purpose of
receiving payment and for all other purposes and shall not be affected by any
notice to the contrary.

         Bonds of this series are not redeemable at the option of the Company
prior to the Stated Maturity Date for any reason, and are not subject to a
sinking fund.

         In the event (i) an Event of Default under and as defined in the Credit
Agreement has occurred under Section 7.1(a) of the Credit Agreement by reason of
a failure by the Company to make a payment of principal when the same shall be
due and payable pursuant to the Credit Agreement or (ii) the Notes (as defined
in the Credit Agreement) are declared due and payable pursuant to Section 7.2 of
the Credit Agreement, then the bonds of this series shall be redeemable in whole
upon receipt by the Trustee of a written demand (a "Redemption Demand") from the
Administrative Agent stating that there has been such an Event of Default and
demanding redemption of the bonds of this series. The Trustee shall, within 5
days after receiving such Redemption Demand, mail a copy thereof to the Company
and the Administrative Agent marked to indicate the date of its receipt by the
Trustee. Promptly upon receipt by the Company of such copy of a Redemption
Demand, the Company shall fix a date on which it will redeem the bonds of this
series so demanded to be redeemed (the "Demand Redemption Date"). Notice of the
date fixed as and for the Demand Redemption Date shall be mailed by the Company
to the Trustee and the Administrative Agent at least 5 days prior to such Demand
Redemption Date. The date to be fixed by the Company as and for the Demand
Redemption Date may be any date up to and including the earlier of (i) the 15th
day after receipt by the Trustee of the Redemption Demand or (ii) the Stated
Maturity Date; provided, however, that if the Trustee and the Administrative
Agent shall not have received such notice fixing the Demand Redemption Date
within 10 days after receipt by the Trustee of the Redemption Demand, the Demand
Redemption Date shall be deemed to be the earlier of (i) the 15th day after
receipt by the

                                       7
<PAGE>

Trustee of the Redemption Demand or (ii) the Stated Maturity Date.
Notwithstanding the foregoing, if an Event of Default or acceleration of Notes
to which this paragraph is applicable is existing on the Stated Maturity Date,
such date shall be deemed to be the Demand Redemption Date without further
action (including actions specified in this paragraph) by the Administrative
Agent, the Trustee or the Company. The bonds of this series shall be redeemed by
the Company on the Demand Redemption Date, upon surrender thereof by the
Administrative Agent to the Trustee, at a redemption price equal to the
principal amount thereof. If a Redemption Demand is rescinded by the
Administrative Agent by written notice to the Trustee prior to the Demand
Redemption Date, no notice of the Demand Redemption Date shall be given, or, if
already given, shall be automatically annulled; but no such rescission shall
extend to or affect any subsequent Event of Default or acceleration of Notes or
impair any right consequent thereon.

         This bond is subject to restrictions on transferability as set forth in
the Security Agreement. This bond is transferable only in accordance with the
provisions of the Security Agreement and the Indenture by the registered owner
hereof in person, or by his duly authorized attorney, at the office of the
Trustee in Chicago, Illinois, or at the option of the registered owner at the
agency of the Company in the Borough of Manhattan, City and State of New York,
or elsewhere if authorized by the Company, upon surrender and cancellation of
this bond, and thereupon a new bond or bonds of the same series and of a like
aggregate principal amount will be issued to the transferee in exchange therefor
as provided in the Indenture, upon payment of taxes or other governmental
charges, if any, that may be imposed in relation thereto.

         Bonds of this series are interchangeable as to denominations in the
manner and upon the conditions prescribed in the Indenture.

         No charge shall be made by the Company for any exchange or transfer of
bonds of this series, other than for taxes or other governmental charges, if
any, that may be imposed in relation thereto.

         No recourse shall be had for the payment of the principal of this bond,
or any part thereof, or of any claim based hereon or in respect hereof or of
said Indenture, against any incorporator, or any past, present, or future
shareholder, officer or director of the Company or of any predecessor or
successor corporation, either directly or through the Company, or through any
such predecessor or successor corporation, or through any receiver or a trustee
in bankruptcy, whether by virtue of any constitution, statute, or rule of law or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released, as more fully provided in the Indenture.

         This bond shall not be valid or become obligatory for any purpose
unless and until the certificate of authentication hereon shall have been signed
by or on behalf of BNY Midwest Trust Company, as Trustee under the Indenture, or
its successor thereunder.

the date of the preparation of the Supplemental Trust Indenture dated as of
August 1, 2002 to be conveyed, assigned, transferred, mortgaged, pledged, set

         WHEREAS, the Indenture provides in substance that the Company and the
Trustee may enter into indentures supplemental thereto for the purposes, among
others, of creating and setting forth the particulars of any new series of bonds
and of providing the terms and conditions of the issue of the bonds of any

ensealing and delivery of these presents, the receipt of which is hereby
acknowledged, and other good and valuable considerations, does hereby covenant
and agree to and with BNY Midwest Trust Company, as

<PAGE>

Trustee, and its successors in the trust under the Indenture for the benefit of
those who hold or shall hold the bonds, or any of them, issued or to be issued
thereunder as follows:

                                   ARTICLE I.
                           FORM AND EXECUTION OF BONDS

         SECTION 1.01. There hereby is created, for issuance under the
Indenture, a series of bonds designated Series due 2004, extendible through 2006
in the aggregate principal amount of $275,000,000, which shall bear the
descriptive title "First Mortgage Bonds, Series due 2004, extendible through
2006" (the "Bonds"), and the form thereof shall contain suitable provisions with
respect to the matters hereafter specified in this Section. The Bonds shall be
issued as registered bonds without coupons in denominations of a multiple of
$1,000 and shall be substantially of the tenor and purport hereinbefore recited.
The principal amount of the Bonds shall be payable on May 14, 2004 (the
"Maturity Date") or upon earlier declaration of acceleration or redemption;
provided, however, that in the event the Commitment Termination Date, under and
as defined in the Credit Agreement, is extended in accordance with the terms of
the Credit Agreement, the Maturity Date shall be automatically extended to the
date of such extended Commitment Termination Date and the principal amount of
the Bonds shall be automatically reduced to the extent of the reductions to the
Commitment Amounts (as defined in the Credit Agreement), if any, made in
accordance with the Credit Agreement without any further act on the part of the
Company or the holders of the Bonds; provided, further, that the Maturity Date
as so extended shall in no event be later than May 12, 2006 (the Maturity Date
or, if extended, the date to which the Maturity Date shall be extended in
accordance with the terms hereof, shall be referred to as the "Stated Maturity
Date"). The Bonds shall not bear interest. Principal on the Bonds shall be
payable at the office of the Trustee in Chicago, Illinois, or, at the option of
the registered owner, at the agency of the Company in the Borough of Manhattan,
City and State of New York. Payment of the principal on the Bonds shall be made
in the lawful money of the United States. Payment of principal on the Bonds
shall be subject to the limitations imposed by the Security Agreement dated as
of May 16, 2003 between the Company and the Administrative Agent (the "Security
Agreement").

         The Bonds are being issued to the Administrative Agent by the Company
pursuant to the Company's obligations under the Credit Agreement and shall be
held by the Administrative Agent subject to the terms of the Credit Agreement
and the Security Agreement.

         It shall be an additional term and condition of the Bonds that, in the
event (i) an Event of Default under and as defined in the Credit Agreement has
occurred under Section 7.1(a) of the Credit Agreement by reason of a failure by
the Company to make a payment of principal when the same shall be due and
payable pursuant to the Credit Agreement or (ii) the Notes (as defined in the
Credit Agreement) are declared due and payable pursuant to Section 7.2 of the
Credit Agreement, then the occurrence of either such event shall be deemed, upon
written notice from the Administrative Agent to the Trustee of the occurrence
thereof, to be a completed default, for purposes of Section 1(a) of Article XIII
of the Original Indenture prior to the Effective Date, and a Completed Default,
for purposes of Section 13.01(a) of the Indenture on and after the Effective
Date, and the definitions of completed default and Completed Default in the
Original Indenture and the Indenture, respectively, are modified accordingly for
purposes of the Bonds.

                                       10
<PAGE>

         The Bonds have been issued by the Company to the Administrative Agent
to (i) provide for the payment of the Company's obligations to make payments to
any person under the Credit Agreement and (ii) provide to such persons the
benefits of the security provided for the Bonds pursuant to the Indenture. The
obligations of the Company under the Bonds may be discharged prior to the Stated
Maturity Date under the circumstances set forth in the Security Agreement.

         SECTION 1.02. The Bonds are not redeemable by the Company prior to the
Stated Maturity Date for any reason and are not subject to a sinking fund.

         In the event (i) an Event of Default under and as defined in the Credit
Agreement has occurred under Section 7.1(a) of the Credit Agreement by reason of
a failure by the Company to make a payment of principal when the same shall be
due and payable pursuant to the Credit Agreement or (ii) the Notes (as defined
in the Credit Agreement) are declared due and payable pursuant to Section 7.2 of
the Credit Agreement, then the Bonds shall be redeemable in whole upon receipt
by the Trustee of a written demand (a "Redemption Demand") from the
Administrative Agent stating that there has been such an Event of Default and
demanding redemption of the Bonds. The Trustee shall, within 5 days after
receiving such Redemption Demand, mail a copy thereof to the Company and the
Administrative Agent marked to indicate the date of its receipt by the Trustee.
Promptly upon receipt by the Company of such copy of a Redemption Demand, the
Company shall fix a date on which it will redeem the Bonds so demanded to be
redeemed (the "Demand Redemption Date"). Notice of the date fixed as and for the
Demand Redemption Date shall be mailed by the Company to the Trustee and the
Administrative Agent at least 5 days prior to such Demand Redemption Date. The
date to be fixed by the Company as and for the Demand Redemption Date may be any
date up to and including the earlier of (i) the 15th day after receipt by the
Trustee of the Redemption Demand or (ii) the Stated Maturity Date; provided,
however, that if the Trustee and the Administrative Agent shall not have
received such notice fixing the Demand Redemption Date within 10 days after
receipt by the Trustee of the Redemption Demand, the Demand Redemption Date
shall be deemed to be the earlier of (i) the 15th day after receipt by the
Trustee of the Redemption Demand or (ii) the Stated Maturity Date.
Notwithstanding the foregoing, if an Event of Default or acceleration of Notes
to which this paragraph is applicable is existing on the Stated Maturity Date,
such date shall be deemed to be the Demand Redemption Date without further
action (including actions specified in this paragraph) by the Administrative
Agent, the Trustee or the Company. The Bonds shall be redeemed by the Company on
the Demand Redemption Date, upon surrender thereof by the Administrative Agent
to the Trustee, at a redemption price equal to the principal amount thereof. If
a Redemption Demand is rescinded by the Administrative Agent by written notice
to the Trustee prior to the Demand Redemption Date, no notice of the Demand
Redemption Date shall be given, or, if already given, shall be automatically
annulled; but no such rescission shall extend to or affect any subsequent Event
of Default or acceleration of Notes or impair any right consequent thereon.

         SECTION 1.03. The registered owner of any Bond or Bonds, at his option
may surrender the same with other Bonds of such series at the office of the
Trustee in Chicago, Illinois, or at the agency of the Company in the Borough of
Manhattan, City and State of New York, or elsewhere if authorized by the
Company, for cancellation, in exchange for other Bonds of such series of higher
or lower authorized denominations, but of the same aggregate principal amount,
and upon receipt of any payment required under the provisions of Section 1.04
hereof. Thereupon the

                                       11
<PAGE>

Company shall execute and deliver to the Trustee and the Trustee shall
authenticate and deliver such other registered bonds to such registered owner at
its office or at any other place specified as aforesaid.

         SECTION 1.04. No charge shall be made by the Company for any exchange
or transfer of Bonds, other than for taxes or other governmental charges, if
any, that may be imposed in relation thereto.

         SECTION 1.05. The Bonds shall be executed on behalf of the Company by
the manual signature of its President or one of its Vice Presidents or with the
facsimile signature of its President, and its corporate seal shall be thereunto
affixed, or printed, lithographed, or engraved thereon, in facsimile, and
attested by the manual signature of its Secretary or one of its Assistant
Secretaries or with the facsimile signature of its Secretary. In case any of the
officers who shall have signed any Bonds or attested the seal thereon or whose
facsimile signature shall be borne by the Bonds shall cease to be such officers
of the Company before the Bonds so signed and sealed actually shall have been
authenticated by the Trustee or delivered by the Company, such Bonds
nevertheless may be issued, authenticated, and delivered with the same force and
effect as though the person or persons who signed such Bonds and attested the
seal thereon or whose facsimile signature is borne by the Bonds had not ceased
to be such officer or officers of the Company. Any Bond issuable hereunder may
be signed or attested by manual or facsimile signature on behalf of the Company
by such person as at the actual date of the execution of such Bond shall be the
proper officer of the Company, although at the date of such Bond such person
shall not have been an officer of the Company.

         SECTION 1.06. The registered holder of all of the Bonds shall be the
Administrative Agent until such time as the Bonds are transferred in accordance
with the Security Agreement and the Indenture.

                                   ARTICLE II.
                      APPOINTMENT OF AUTHENTICATING AGENT.

         SECTION 2.01. The Trustee shall, if requested in writing so to do by
the Company, promptly appoint an agent or agents of the Trustee who shall have
authority to authenticate registered Bonds, in the name and on behalf of the
Trustee. Such appointment by the Trustee shall be evidenced by a certificate of
a vice-president of the Trustee delivered to the Company prior to the
effectiveness of such appointment.

         SECTION 2.02. (a) Any such authenticating agent shall be acceptable to
the Company and at all times shall be a corporation which is organized and doing
business under the laws of the United States or of any State, is authorized
under such laws to act as authenticating agent, has a combined capital and
surplus of at least $10,000,000, and is subject to supervision or examination by
Federal or State authority. If such corporation publishes reports of condition
at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 2.02
the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published.

                                       12
<PAGE>

         (b)      Any corporation into which any authenticating agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion, or consolidation to which any
authenticating agent shall be a party, or any corporation succeeding to the
corporate agency business of any authenticating agent, shall continue to be the
authenticating agent without the execution or filing of any paper or any further
act on the part of the Trustee or the authenticating agent.

         (c)      Any authenticating agent at any time may resign by giving
written notice of resignation to the Trustee and to the Company. The Trustee may
at any time, and upon written request of the Company to the Trustee shall,
terminate the agency of any authenticating agent by giving written notice of
termination to such authenticating agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible in accordance with the
provisions of this Section 2.02, the Trustee, unless otherwise requested in
writing by the Company, promptly shall appoint a successor authenticating agent,
which shall be acceptable to the Company. Any successor authenticating agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers, duties, and responsibilities of its predecessor hereunder, with
like effect as if originally named. No successor authenticating agent shall be
appointed unless eligible under the provisions of this Section 2.02.

         (d)      The Company agrees to pay to any authenticating agent,
appointed in accordance with the provisions of this Section 2.02, reasonable
compensation for its services.

         SECTION 2.03. If an appointment is made pursuant to this Article II,
the registered Bonds, shall have endorsed thereon, in addition to the Trustee's
Certificate, an alternate Trustee's Certificate in the following form:

        This bond is one of the bonds of the Series designated thereon,
                  described in the within-mentioned Indenture.

                                                        Authorized Officer.

         SECTION 2.04. No provision of this Article II shall require the Trustee
to have at any time more than one such authenticating agent for any one State or
to appoint any such authenticating agent in the State in which the Trustee has
its principal place of business.

          2. Registration Under the Securities Act.

         (a) Except as set forth in Section 2(b) below, the Company agrees to
     file under the Securities Act, as soon as practicable, but no later than
     120 days after the Closing Date, a registration statement relating to an
     offer to exchange (such registration statement, the "Exchange Registration
     Statement", and such offer, the "Exchange Offer") any and all of the
     Securities for a like aggregate principal amount of debt securities to be
     issued by the Company, which debt securities are to be substantially
     identical to the Securities (and will be entitled to the benefits of a
     trust indenture which is substantially identical to the Indenture or is the
     Indenture and which has been qualified under the Trust Indenture Act),
     except that they will have been registered pursuant to an effective
     registration statement under the Securities Act and do not contain
     provisions for the liquidated damages contemplated in Section 2(c) below
     (such new debt securities hereinafter called "Exchange Securities"). The
     Company agrees to use its best efforts to cause the Exchange Registration
     Statement to become effective under the Securities Act as soon as
     practicable, but no later than 180 days after the Closing Date. The
     Exchange Offer will be registered under the Securities Act on the
     appropriate form and will comply with all applicable tender offer rules and
     regulations under the Exchange Act. The Company further agrees to use its
     best efforts to commence and complete the Exchange Offer promptly, but no
     later than 45 days after such registration statement has become effective,
     hold the Exchange Offer open for at least 30 days and exchange Exchange
     Securities for all Registrable Securities that have been properly tendered
     and not withdrawn on or prior to the expiration of the Exchange Offer. The
     Exchange Offer will be deemed to have been "completed" only if the debt
     securities received by holders other than Restricted Holders in the
     Exchange Offer for Registrable Securities are, upon receipt, transferable
     by each such holder without restriction under the Securities Act and the
     Exchange Act and without material restrictions under the blue sky or
     securities laws of a substantial majority of the States of the United
     States of America. The Exchange Offer shall be deemed to have been
     completed upon the earlier to occur of (i) the Company having exchanged the
     Exchange Securities for all outstanding Registrable Securities pursuant to
     the Exchange Offer and (ii) the Company having exchanged, pursuant to the
     Exchange Offer, Exchange Securities for all Registrable Securities that
     have been properly tendered and not withdrawn before the expiration of the
     Exchange Offer, which shall be on a date that is at least 30 days following
     the commencement of the Exchange Offer. The Company agrees (x) to include
     in the Exchange Registration Statement a prospectus for use in any resales
     by any holder of Exchange Securities that is a broker-dealer and (y) to
     keep such Exchange Registration Statement effective for a period (the
     "Resale Period") beginning when Exchange Securities are first issued in the
     Exchange Offer and ending upon the earlier of the expiration of the 180th
     day after the Exchange Offer has been completed or such time as such
     broker-dealers no longer own any Registrable Securities. With respect to
     such Exchange Registration Statement, such holders shall have the benefit
     of the rights of indemnification and contribution set forth in Sections
     6(a), (c), (d) and (e) hereof.

         (b) If (i) on or prior to the time the Exchange Offer is completed
     existing Commission interpretations are changed such that the Exchange
     Securities received by holders other

                                       4
<PAGE>

     than Restricted Holders in the Exchange Offer for Registrable Securities
     are not or would not be, upon receipt, transferable by each such holder
     without restriction under the Securities Act, (ii) the Exchange Offer has
     not been completed within 225 days following the Closing Date or (iii) the
     Exchange Offer is not available to any holder of the Securities, the
     Company shall, in lieu of (or, in the case of clause (iii), in addition to)
     conducting the Exchange Offer contemplated by Section 2(a), file under the
     Securities Act as soon as practicable, but no later than 90 days after the
     time such obligation to file arises, a "shelf" registration statement
     providing for the registration of, and the sale on a continuous or delayed
     basis by the holders of, all of the Registrable Securities, pursuant to
     Rule 415 or any similar rule that may be adopted by the Commission (such
     filing, the "Shelf Registration" and such registration statement, the
     "Shelf Registration Statement"). The Company agrees to use its best efforts
     (x) to cause the Shelf Registration Statement to become or be declared
     effective no later than 120 days after such Shelf Registration Statement is
     filed and to keep such Shelf Registration Statement continuously effective
     for a period ending on the earlier of the second anniversary of the
     Effective Time or such time as there are no longer any Registrable
     Securities outstanding, provided, however, that no holder shall be entitled
     to be named as a selling securityholder in the Shelf Registration Statement
     or to use the prospectus forming a part thereof for resales of Registrable
     Securities unless such holder is an Electing Holder and provided, further,
     that no holder (other than the Purchasers) shall be entitled to have the
     Registrable Securities held by it covered by such Shelf Registration
     Statement unless such holder agrees in writing to be bound by all of the
     provisions of this Exchange and Registration Rights Agreement applicable to
     such holder, and (y) after the Effective Time of the Shelf Registration
     Statement, promptly upon the request of any holder of Registrable
     Securities that is not then an Electing Holder, to take any action
     reasonably necessary to enable such holder to use the prospectus forming a
     part thereof for resales of Registrable Securities, including, without
     limitation, any action necessary to identify such holder as a selling
     securityholder in the Shelf Registration Statement, provided, however, that
     nothing in this clause (y) shall relieve any such holder of the obligation
     to return a completed and signed Notice and Questionnaire to the Company in
     accordance with Section 3(d)(iii) hereof. The Company further agrees to
     supplement or make amendments to the Shelf Registration Statement, as and
     when required by the rules, regulations or instructions applicable to the
     registration form used by the Company for such Shelf Registration Statement
     or by the Securities Act or rules and regulations thereunder for shelf
     registration, and the Company agrees to furnish to each Electing Holder
     copies of any such supplement or amendment prior to its being used or
     promptly following its filing with the Commission.

         (c) In the event that (i) the Company has not filed the Exchange
     Registration Statement or Shelf Registration Statement on or before the
     date on which such registration statement is required to be filed pursuant
     to Section 2(a) or 2(b), respectively, (ii) such Exchange Registration
     Statement or Shelf Registration Statement has not become effective or been
     declared effective by the Commission on or before the date on which such
     registration statement is required to become or be declared effective
     pursuant to Section 2(a) or 2(b), respectively, (iii) the Exchange Offer
     has not been completed within 45 days after the initial effective date of
     the Exchange Registration Statement relating to the Exchange Offer (if the
     Exchange Offer is then required to be made) or (iv) during any time that
     the Company is required by Section 2(a) or 2(b) to maintain an effective
     Exchange Registration Statement or Shelf Registration Statement, any
     Exchange Registration Statement or Shelf Registration Statement required by
     Section 2(a) or 2(b) hereof is filed and declared effective but shall
     thereafter either be withdrawn by the Company or shall become subject to an
     effective stop order issued pursuant to Section 8(d) of the Securities Act
     suspending the effectiveness of

                                       5
<PAGE>

     such registration statement (except as specifically permitted herein)
     without being succeeded immediately by an additional registration statement
     filed and declared effective (each such event referred to in clauses (i)
     through (iv), a "Registration Default" and each period during which a
     Registration Default has occurred and is continuing, a "Registration
     Default Period"), then, as liquidated damages for such Registration Default
     ("Liquidated Damages"), subject to the provisions of Section 9(b), the
     Company shall pay, from and including the date on which any such
     Registration Default shall occur to and including the first week in which
     all such Registration Defaults have been cured, an amount equal to $0.10
     per week per $1,000 principal amount of outstanding Securities, in addition
     to the interest set forth in the title of the Securities.

         (d) The Company shall take all actions necessary or advisable to be
     taken by it to ensure that the transactions contemplated herein are
     effected as so contemplated.

         (e) Any reference herein to a registration statement as of any time
     shall be deemed to include any document incorporated, or deemed to be
     incorporated, therein by reference as of such time and any reference herein
     to any post-effective amendment to a registration statement as of any time
     shall be deemed to include any document incorporated, or deemed to be
     incorporated, therein by reference as of such time.

         3. Registration Procedures.

            If the Company files a registration statement pursuant to Section
2(a) or Section 2(b), the following provisions shall apply:

         (a) At or before the Effective Time of the Exchange Offer or the Shelf
     Registration, as the case may be, the Company shall qualify the Indenture
     under the Trust Indenture Act.

         (b) 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.

         (c) In connection with the Company's obligations with respect to the

     practicable (or as otherwise specified):

                 (i)    prepare and file with the Commission, as soon as
             practicable but no later than 120 days after the Closing Date, an
             Exchange Registration Statement on any form which may be utilized
             by the Company and which shall permit the Exchange Offer and
             resales of Exchange Securities by broker-dealers during the
             Resale Period to be effected as contemplated by Section 2(a), and
             use its best efforts to cause such Exchange Registration
             Statement to become effective as soon as practicable thereafter,
             but no later than 180 days after the Closing Date;

                 (ii)   as soon as practicable prepare and file with the

             or any prospectus amendment or supplement or post-effective
             amendment has been filed, and, with respect to such Exchange
             Registration Statement or any post-effective amendment, when the

             Resale Period when a prospectus is required to be delivered under
             the Securities Act, that such Exchange Registration Statement,
             prospectus, prospectus amendment or supplement or post-effective
             amendment does not conform in all material respects to the
             applicable requirements of the Securities Act and the Trust
             Indenture Act and the rules and regulations of the Commission
             thereunder or contains an untrue statement of a material fact or

             pursuant to Section 3(e)(iii)(F) above, to notify any
             broker-dealers holding Exchange Securities, without delay prepare
             and furnish to each such holder a reasonable number of copies of a
             prospectus supplemented or amended so that, as thereafter delivered
             to purchasers of such Exchange Securities during the Resale Period,
             such prospectus shall conform in all material respects to the
             applicable requirements of the Securities Act and the Trust
             Indenture Act and the rules and regulations of the Commission
             thereunder and shall not contain an untrue statement of a material

<PAGE>

             continuance of offers, sales and dealings therein in such
             jurisdictions until the expiration of the Resale Period and (C)
             take any and all other actions as may be reasonably necessary or
             advisable to enable each broker-dealer holding Exchange Securities
             to consummate the disposition thereof in such jurisdictions;
             provided, however, that the Company shall not be required for any
             such purpose to (1) qualify as a foreign corporation in any

             soon as practicable but no later than 18 months after the effective
             date of such Exchange Registration Statement, an earnings statement
             of the Company and its subsidiaries complying with Section 11(a) of
             the Securities Act (including, at the option of the Company, Rule
             158 thereunder).

             text of the amendment or waiver proposed or effected, as the case
             may be;

             Exchange Act shall underwrite any Registrable 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 "Conduct Rules") of the National Association of
             Securities Dealers, Inc. ("NASD") or any successor thereto, as
             amended from time to time) thereof, whether as a holder of such
             Registrable Securities or as an underwriter, a placement or sales
             agent or a broker or dealer in respect thereof, or otherwise,
             assist such broker-dealer in complying with the requirements of
             such Conduct Rules, including by providing such information to such
             broker-dealer as may be required in order for such broker-dealer to
             comply with the requirements of the Conduct Rules; and

                 (xx)   comply with all applicable rules and regulations of the
             Commission, and make generally available to its securityholders as
             soon as practicable but in any event not later than 18 months after
             the effective date of such Shelf Registration Statement, an
             earnings statement of the Company and its subsidiaries complying
             with Section 11(a) of the Securities Act (including, at the option
             of the Company, Rule 158 thereunder).

         (e) In the event that the Company would be required, pursuant to
     Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement
     or sales agent, if any, therefor and the managing underwriters, if any,
     thereof, the Company shall without delay prepare and furnish to each of the
     Electing Holders, to each placement or sales agent, if any, and to each
     such underwriter, if any, a reasonable number of copies of a prospectus
     supplemented or amended so that, as thereafter delivered to purchasers of
     Registrable Securities, such prospectus shall conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder
     and shall not 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 in light of the circumstances then
     existing. Each Electing Holder agrees that upon receipt of any notice from
     the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder
     shall forthwith discontinue the disposition of Registrable Securities
     pursuant to the Shelf Registration Statement applicable to such Registrable
     Securities until such Electing Holder shall have received copies of such
     amended or supplemented prospectus, and if so directed by the Company, such
     Electing Holder shall deliver to the Company (at the Company's expense) all
     copies, other than permanent file copies, then in such Electing Holder's
     possession of the prospectus covering such Registrable Securities at the
     time of receipt of such notice.

         (f) In the event of a Shelf Registration, in addition to the
     information required to be provided by each Electing Holder in its Notice
     Questionnaire, the Company may require such Electing Holder to furnish to
     the Company such additional information regarding such Electing Holder and
     such Electing Holder's intended method of distribution of Registrable
     Securities as may be required in order to comply with the Securities Act.
     Each such Electing Holder agrees to notify the Company as promptly as
     practicable of any inaccuracy or change in information previously furnished
     by such Electing Holder to the Company or of the occurrence of any event in
     either case as a result of which any prospectus relating to such Shelf
     Registration contains or would contain an untrue statement of a material
     fact regarding such Electing Holder or such Electing Holder's intended
     method of disposition of such Registrable Securities or omits to state any
     material fact

                                       14
<PAGE>

     regarding such Electing Holder or such Electing Holder's
     intended method of disposition of such Registrable Securities required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing, and promptly to
     furnish to the Company any additional information required to correct and
     update any previously furnished information or required so that such
     prospectus shall not contain, with respect to such Electing Holder or the
     disposition of such Registrable Securities, 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 in light
     of the circumstances then existing.

         (g) Until the expiration of two years after the Closing Date, the
     Company will not, and will not permit any of its "affiliates" (as defined
     in Rule 144) to, resell any of the Securities that have been reacquired by
     any of them except pursuant to an effective registration statement under
     the Securities Act.

         4. Registration Expenses.

            The Company agrees to bear and to pay or cause to be paid promptly
all expenses incident to the Company's performance of or compliance with this
Exchange and Registration Rights Agreement, including (a) all Commission and any

qualification and determination, (c) all expenses relating to the preparation,

of documents referred in clause (c) above, (e) fees and expenses of the Trustee

independent certified public accountants of the Company (including the expenses
of any opinions or "cold comfort" letters required by or incident to such

fees charged by securities rating services for rating the Securities and (j)
fees, expenses and disbursements of any other persons, including special
experts, retained by the Company in connection with such registration

Expenses are incurred, assumed

                                       15
<PAGE>

or paid by any holder of Registrable Securities or any placement or sales agent
therefor or underwriter thereof, the Company shall reimburse such person for the
full amount of the Registration Expenses so incurred, assumed or paid promptly
after receipt of a request therefor. Notwithstanding the foregoing, the holders
of the Registrable Securities being registered shall pay all agency fees and
commissions and underwriting discounts and commissions attributable to the sale
of such Registrable Securities and the fees and disbursements of any counsel or
other advisors or experts retained by such holders (severally or jointly), other
than the counsel and experts specifically referred to above.

         5. Representations and Warranties.

            The Company represents and warrants to, and agrees with, each
Purchaser and each of the holders from time to time of Registrable Securities
that:

         (a) Each registration statement covering Registrable Securities and
     each prospectus (including any preliminary or summary prospectus) contained
     therein or furnished pursuant to Section 3(c) or Section 3(d) hereof and
     any further amendments or supplements to any such registration statement or
     prospectus, when it becomes effective or is filed with the Commission, as
     the case may be, and, in the case of an underwritten offering of
     Registrable Securities, at the time of the closing under the underwriting
     agreement relating thereto, will conform in all material respects to the
     requirements of the Securities Act and the Trust Indenture Act and the
     rules and regulations of the Commission thereunder and will not 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 at all times subsequent to the Effective Time when a
     prospectus would be required to be delivered under this Exchange and
     Registration Rights Agreement the Securities Act, other than from (i) such
     time as a notice has been given to holders of Registrable Securities
     pursuant to Section 3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii)
     such time as the Company furnishes an amended or supplemented prospectus
     pursuant to Section 3(c)(iv) or Section 3(e) hereof, each such registration
     statement, and each prospectus (including any summary prospectus) contained
     therein or furnished pursuant to Section 3(c) or Section 3(d) hereof, as
     then amended or supplemented, will conform in all material respects to the
     requirements of the Securities Act and the Trust Indenture Act and the
     rules and regulations of the Commission thereunder and will not 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 in the light of the circumstances then existing; provided,
     however, that this representation and warranty shall not apply to any
     statements or omissions made in reliance upon and in conformity with
     information furnished in writing to the Company by a holder of Registrable
     Securities expressly for use therein; provided, further, that the foregoing
     indemnity with respect to any untrue statement contained in or omission
     from any preliminary prospectus shall not inure to the benefit of any
     holder (or any of the directors, officers, employees and agents of such
     holder or any person controlling such holder) from whom the person
     asserting any such loss, claim, damage or liability purchased the
     Securities which are the subject thereof if such person did not receive a
     copy of the final prospectus (or the final prospectus as then amended or
     supplemented if the Company shall have furnished any amendments or
     supplements thereto) at or prior to the confirmation of the sale of such
     Securities to such person in any case where such delivery is required by
     the Securities Act and the untrue statement or omission of a material fact
     contained in such preliminary prospectus was corrected in the final
     prospectus (or the final prospectus as so amended or supplemented if the
     Company shall have furnished any amendments or supplements thereto), and it
     is finally judicially determined that such delivery was required to

                                       16
<PAGE>

     be made under the Securities Act and was not so made. This indemnity
     agreement will be in addition to any liability which the Company may
     otherwise have.

         (b) Any documents incorporated by reference in any prospectus referred
     to in Section 5(a) hereof, when they become or became effective or are or
     were filed with the Commission, as the case may be, will conform or
     conformed in all material respects to the requirements of the Securities
     Act or the Exchange Act, as applicable, and none of such documents will
     contain or contained an untrue statement of a material fact or will omit or
     omitted to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading; provided, however, that this
     representation and warranty shall not apply to any statements or omissions
     made in reliance upon and in conformity with information furnished in
     writing to the Company by a holder of Registrable Securities expressly for
     use therein.

         (c) The compliance by the Company with all of the provisions of this
     Exchange and Registration Rights Agreement and the consummation of the
     transactions herein contemplated will not conflict with or result in a
     breach of any of the terms or provisions of, or constitute a default under,
     any indenture, mortgage, deed of trust, loan agreement or other agreement
     or instrument to which the Company or any subsidiary of the Company is a
     party or by which the Company or any subsidiary of the Company is bound or
     to which any of the property or assets of the Company or any subsidiary of
     the Company is subject, nor will such action result in any violation of the
     provisions of the certificate of incorporation, as amended, or the by-laws
     of the Company or any statute or any order, rule or regulation of any court
     or governmental agency or body having jurisdiction over the Company or any
     subsidiary of the Company or any of their properties; and no consent,
     approval, authorization, order, registration or qualification of or with
     any such court or governmental agency or body is required for the
     consummation by the Company of the transactions contemplated by this
     Exchange and Registration Rights Agreement, except the registration under
     the Securities Act of the Securities, qualification of the Indenture under
     the Trust Indenture Act and such consents, approvals, authorizations,
     registrations or qualifications as may be required under State securities
     or blue sky laws in connection with the offering and distribution of the
     Securities.

         (d) This Exchange and Registration Rights Agreement has been duly
     authorized, executed and delivered by the Company.

         6. Indemnification.

         (a) Indemnification by the Company. The Company will indemnify and
     hold harmless each of the holders of Registrable Securities included in an
     Exchange Registration Statement, each of the Electing Holders of
     Registrable Securities included in a Shelf Registration Statement and each
     person who participates as a placement or sales agent or as an underwriter
     in any offering or sale of such Registrable Securities against any losses,
     claims, damages or liabilities, joint or several, to which such holder,
     agent or underwriter may become subject under the Securities Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereof) arise out of or are based upon an untrue
     statement or alleged untrue statement of a material fact contained in any
     Exchange Registration Statement or Shelf Registration Statement, as the
     case may be, under which such Registrable Securities were registered under
     the Securities Act, or any preliminary, final or summary prospectus
     contained therein or furnished by the Company to any such holder, Electing
     Holder, agent or underwriter, or any amendment or supplement thereto, or
     arise out of or are based upon the omission or alleged omission to state
     therein a material

                                       17
<PAGE>

     fact required to be stated therein or necessary to make the statements
     therein not misleading, and will reimburse such holder, such Electing
     Holder, such agent and such underwriter for any legal or other expenses
     reasonably incurred by them in connection with investigating or defending
     any such action or claim as such expenses are incurred; provided, however,
     that the Company shall not be liable to any such person in any such case to
     the extent that any such loss, claim, damage or liability arises out of or
     is based upon an untrue statement or alleged untrue statement or omission
     or alleged omission made in such registration statement, or preliminary,
     final or summary prospectus, or amendment or supplement thereto, in
     reliance upon and in conformity with written information furnished to the
     Company by such person expressly for use therein.

         (b) Indemnification by the Holders and any Agents and Underwriters.
     The Company may require, as a condition to including any Registrable
     Securities in any registration statement filed pursuant to Section 2(b)
     hereof and to entering into any underwriting agreement with respect
     thereto, that the Company shall have received an undertaking reasonably
     satisfactory to it from the Electing Holder of such Registrable Securities
     and from each underwriter named in any such underwriting agreement,
     severally and not jointly, to (i) indemnify and hold harmless the Company
     and all other holders of Registrable Securities, against any losses,
     claims, damages or liabilities to which the Company or such other holders
     of Registrable Securities may become subject, under the Securities Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereof) arise out of or are based upon an untrue
     statement or alleged untrue statement of a material fact contained in such
     registration statement, or any preliminary, final or summary prospectus
     contained therein or furnished by the Company to any such Electing Holder,
     agent or underwriter, or any amendment or supplement thereto, 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, in each case to the extent, but only to
     the extent, that such untrue statement or alleged untrue statement or
     omission or alleged omission was made in reliance upon and in conformity
     with written information furnished to the Company by such Electing Holder
     or underwriter expressly for use therein, and (ii) reimburse the Company
     for any legal or other expenses reasonably incurred by the Company in
     connection with investigating or defending any such action or claim as such
     expenses are incurred; provided, however, that no such Electing Holder
     shall be required to undertake liability to any person under this Section
     6(b) for any amounts in excess of the dollar amount of the proceeds to be
     received by such Electing Holder from the sale of such Electing Holder's
     Registrable Securities pursuant to such registration.

         (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
     party under clause (a) or (b) above of written notice of the commencement
     of any action, such indemnified party shall, if a claim in respect thereof
     is to be made against an indemnifying party pursuant to the indemnification
     provisions of or contemplated by this Section 6, notify such indemnifying
     party in writing of the commencement of such action; but the omission so to
     notify the indemnifying party shall not relieve it from any liability which
     it may have to any indemnified party otherwise than under the
     indemnification provisions of or contemplated by Section 6(a) or 6(b)
     hereof. In case any such action shall be brought against any indemnified
     party and it shall notify an indemnifying party of the commencement
     thereof, such indemnifying party shall be entitled to participate therein
     and, to the extent that it shall 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

                                       18
<PAGE>

     assume the defense thereof, such indemnifying party shall not be liable to
     such indemnified party for any legal expenses of other counsel or any other
     expenses, in each case subsequently incurred by such indemnified party, in
     connection with the defense thereof other than reasonable costs of
     investigation. No indemnifying party shall, without the written consent of
     the indemnified party, effect the settlement or compromise of, or consent
     to the entry of any judgment with respect to, any pending or threatened
     action or claim in respect of which indemnification or contribution may be
     sought hereunder (whether or not the indemnified party is an actual or
     potential party to such action or claim) unless such settlement, compromise
     or judgment (i) includes an unconditional release of the indemnified party
     from all liability arising out of such action or claim 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) Contribution. If for any reason the indemnification provisions
     contemplated by Section 6(a) or Section 6(b) are unavailable to or
     insufficient to hold harmless an indemnified party in respect of any
     losses, claims, damages or liabilities (or actions in respect thereof)
     referred to therein, then each indemnifying party shall contribute to the
     amount paid or payable by such indemnified party as a result of such
     losses, claims, damages or liabilities (or actions in respect thereof) in
     such proportion as is appropriate to reflect the relative fault of the
     indemnifying party and the indemnified party in connection with the
     statements or omissions which 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 such indemnifying party and
     indemnified party shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or
     omission or alleged omission to state a material fact relates to
     information supplied by such indemnifying party or by such indemnified
     party, and the parties' relative intent, knowledge, access to information
     and opportunity to correct or prevent such statement or omission. The
     parties hereto agree that it would not be just and equitable if
     contributions pursuant to this Section 6(d) were determined by pro rata
     allocation (even if the holders or any agents or underwriters or all of
     them were treated as one entity for such purpose) or by any other method of
     allocation which does not take account of the equitable considerations
     referred to in this Section 6(d). The amount paid or payable by an
     indemnified party as a result of the losses, claims, damages, or
     liabilities (or actions in respect thereof) referred to above shall be
     deemed to include any legal or other fees or expenses reasonably incurred
     by such indemnified party in connection with investigating or defending any
     such action or claim. Notwithstanding the provisions of this Section 6(d),
     no holder shall be required to contribute any amount in excess of the
     amount by which the dollar amount of the proceeds received by such holder
     from the sale of any Registrable Securities (after deducting any fees,
     discounts and commissions applicable thereto) exceeds the amount of any
     damages which such holder has otherwise been required to pay by reason of
     such untrue or alleged untrue statement or omission or alleged omission,
     and no underwriter shall be required to contribute any amount in excess of
     the amount by which the total price at which the Registrable Securities
     underwritten by it and distributed to the public were offered to the public
     exceeds the amount of any damages which such underwriter has 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. The holders' and any underwriters'
     obligations in this Section 6(d) to contribute shall be several in
     proportion to the principal amount of Registrable Securities registered or
     underwritten, as the case may be, by them and not joint.

                                       19
<PAGE>

         (e) The obligations of the Company under this Section 6 shall be in
     addition to any liability which the Company may otherwise have and shall
     extend, upon the same terms and conditions, to each officer, director and
     partner of each holder, agent and underwriter and each person, if any, who
     controls any holder, agent or underwriter within the meaning of the
     Securities Act; and the obligations of the holders and any agents or
     underwriters contemplated by this Section 6 shall be in addition to any
     liability which the respective holder, agent or underwriter may otherwise
     have and shall extend, upon the same terms and conditions, to each officer
     and director of the Company (including any person who, with his consent, is
     named in any registration statement as about to become a director of the
     Company) and to each person, if any, who controls the Company within the
     meaning of the Securities Act.

         7. Underwritten Offerings.

         (a) Selection of Underwriters. If any of the Registrable Securities
     covered by the Shelf Registration are to be sold pursuant to an
