            (a) Interest on this Note that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Holder at

include interest accrued from and including the immediately preceding Interest
Payment Date in respect of which interest has been paid or duly provided for (or
from and including June 28, 2001 if no interest has been paid or duly provided

proposed to be paid on this Note and the date of the proposed payment, and at
the same time the Company shall deposit an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Holder for such deposit prior to the
date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Holder entitled to such Defaulted Interest as in this clause
provided. Thereupon the Company shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Holder of the notice of the proposed payment. The
Company shall promptly notify the Holder of such Special Record Date and, in the

payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to the Holder at his address as it appears
in the Security Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special

shall be paid to the Holder at the close of business on such Special Record
Date.

<PAGE>

            If an Event of Default with respect to this Note occurs, then and in
every such case, so long as such Event of Default shall not have been remedied,
unless the principal of this Note shall have already become due and payable, the
Holder, by notice in writing to the Company may declare the principal amount of
and all accrued but unpaid interest on this Note to be due and payable
immediately, and upon any such declaration such principal amount (or specified
amount) and interest shall become immediately due and payable, anything herein
to the contrary notwithstanding. Upon payment in full of such amounts in
Dollars, all obligations of the Company in respect of the payment of principal
of and interest on this Note shall terminate. This provision, however, is
subject to the condition that if, at any time after the principal of this Note
shall have been so declared due and payable, and before any judgment or decree
for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Company shall pay a sum in Dollars, sufficient to pay
all matured installments of interest upon this Note and the principal of this
Note which shall have become due otherwise than by acceleration (with interest
on such principal and to the extent that payment of such interest is enforceable
under applicable law, on overdue installments of interest, at the rate borne by
this Note) and the reasonable expenses of the Holder, and any and all Events of
Default, other than the nonpayment of principal on this Note which shall have
become due as a result of the acceleration being rescinded, shall have been
cured, remedied or waived, then, and in every such case, the Holder by written
notice to the Company, may waive all defaults and rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default, or shall impair any
right consequent thereon.

            In case the Holder shall have proceeded to enforce any right under
this Note and such proceedings shall have been discontinued or abandoned because
of such rescission or annulment or for any other reason or shall have been
determined adversely to the Holder, then, and in every such case, the Company
and the Holder shall be restored respectively to their several positions and
rights hereunder, and all rights, remedies and powers of the Company and the
Holder shall continue as though no such proceedings had been taken.

Section 303. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND INTEREST.

         The Holder shall have the right, which is absolute and unconditional,
to receive payment of the principal of and (subject to Section 202) interest on
the respective Stated Maturity expressed in this Note and to institute suit for
the enforcement of any such payment, and such right shall not be impaired
without the consent of the Holder.

Section 304. RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided elsewhere herein, no right or remedy
herein conferred upon or reserved to the Holder is intended to be exclusive of
any other right or

                                       15
<PAGE>

remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 305. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Holder to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy made available herein or by law to the Holder may be
exercised from time to time, and as often as may be deemed expedient, by the
Holder.

Section 306. WAIVER OF PAST DEFAULTS.

         The Holder may waive any past default hereunder and its consequences.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured for every
purpose of this Note; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

terms herein. The interest on this Note shall be payable without presentation of
this Note, and only to or upon the written order of the Holder thereof and may

            The Company shall pay interest on overdue principal at a rate equal
to 2% over the Interest Rate, and it shall pay interest on overdue installations
of interest at the same rate to the extent lawful.

Section 402.  OPTIONAL PREPAYMENTS.

            The Company may, at its option, upon notice as provided below,
prepay at any time all, or from time to time any part of, this Note, at 100% of
the principal amount so

                                       16
<PAGE>

prepaid, plus accrued and unpaid interest on such amount. The Company will give
the Holder written notice of each optional prepayment under this Section 402 not
less than 15 days and not more than 60 days prior to the date fixed for such
prepayment. Each such notice shall specify such date, the aggregate principal
amount of this Note to be prepaid, and the interest to be paid on the prepayment
date with respect to such principal amount being repaid.

Section 403.  MATURITY; SURRENDER, ETC.

            In the case of each prepayment of this Note pursuant to this Article
IV, the principal amount of this Note to be prepaid shall mature and become due
and payable on the date fixed for such prepayment, together with interest on
such principal amount accrued and unpaid to such date. From and after such date,
unless the Company shall fail to pay such principal amount when so due and
payable, as aforesaid, interest on such principal amount shall cease to accrue.
If this Note is paid or prepaid in full it shall be surrendered to the Company
and cancelled and shall not be reissued. A new Note shall not be issued in lieu
of any prepaid principal amount of any Note. If this Note is prepaid in part a
new note shall be issued representing the aggregate principal amount of the Note
not prepaid.

Section 404.  EXCHANGE.

            (a) At its option, the Initial Holder may in connection with the
transfer of this Note in whole or in part to one or more unaffiliated third
parties exchange the Note or portion thereof into a like aggregate principal
amount of debt securities of the Company (the "Exchange Notes") having the same
Interest Rate and Maturity Date as this Note and which Exchange Notes shall be
in the form attached as Annex A hereto and shall be issued under the indenture
dated May 15, 2000 (the "Indenture"), between the Company and Chase Manhattan
Trust Company, N.A., as trustee (the "Trustee"), on substantially the same terms
as the $4,000,000,000 7.50% Notes due 2011 issued under such Indenture and
offered pursuant to a prospectus supplement dated May 9, 2001 to a prospectus
dated May 9, 2001, and duly authenticated by the Trustee pursuant to the
Company's instructions; PROVIDED, that the Exchange Notes will provide for
transfer restrictions and legends in accordance with applicable law and
registration rights. In the event of a prepayment of the Note under Section 402,
the right to exchange the Note or portion thereof subject to prepayment will
terminate at the close of business on the Business Day immediately preceding the
date fixed for such prepayment and such right shall be lost if not exercised
prior to such time.

            (b) To exchange the Note, the Initial Holder must (i) surrender the
Note to be exchanged, duly endorsed in a form satisfactory to the Company, at
the office of the Company, (ii) notify the Company at such office of the
election to exchange the Note and the aggregate principal amount thereof to be
exchanged and the proposed date of such

                                       17
<PAGE>

exchange which date shall be not less than 10 days from the date of such notice,
(iii) state in writing the name or names in which the certificate or
certificates for such Exchange Notes are to be issued, and (iv) pay any transfer
or similar tax if required. In the event that the Initial Holder fails to notify
the Company of the aggregate principal amount to be exchanged, the Initial
Holder shall be deemed to have elected to exchange 100% of the aggregate
principal amount of the Note. The later of (A) the date on which the Initial
Holder satisfies (i) through (iv) above, and (B) if the Initial Holder satisfies
(i) through (iv) above prior to such 10th day, the date which is 10 days from
the delivery of the notice referred to in (ii) is the "Exchange Date". On the
Exchange Date, the Company shall deliver a certificate or certificates for the
aggregate principal amount of Exchange Notes issuable upon the exchange duly
executed by the Company and duly authenticated by the Trustee, and a new
certificate representing the aggregate principal amount of the Note not
exchanged, if any. The person in whose name an Exchange Note is registered shall
be treated as the holder of the Exchange Note of record on and after the
Exchange Date. No payment will be made for accrued and unpaid interest on the
Note or portion thereof surrendered for exchange, but interest on any Exchange
Note issued shall accrue from the last Interest Payment Date as to which
interest was paid on the Note. If the Note is surrendered for exchange during
the period from the close of business on any record date for the payment of
interest to the opening of business of the corresponding Interest Payment Date,
the Note must be accompanied by a payment in cash in an amount equal to the
interest payable on such Interest Payment Date. If the last day on which the
Note may be exchanged is not a Business Day, the Note may be surrendered for
exchange on the next succeeding Business Day.

            (c) If the Initial Holder exchanges the Note or portion thereof, the
Company shall pay any documentary, stamp or similar issue or transfer tax due on
the exchange of the Note into Exchange Notes. However, the Initial Holder shall
pay any such tax that is due because the Exchange Notes are issued in a name
other than the Initial Holder's name.

            (d) Upon any exchange of this Note for Exchange Notes, the Company
shall enter into a Registration Rights Agreement substantially in the form of
Annex B for the benefit of the holder of the Exchange Note.

            "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 Notes 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 such Notes.

            "Comparable Treasury Price" means, with respect to any Redemption
Date, (i) the average of four Reference U.S. Treasury Dealer Quotations for that
Redemption Date, after excluding the highest and lowest of such Reference U.S.
Treasury Dealer Quotations; or (ii) if the Trustee obtains fewer than four
Reference U.S. Treasury Dealer Quotations, the average of all quotations
obtained by the Trustee.

            "Independent Investment Banker" means one of the Reference U.S.
Treasury Dealers, to be appointed by the Company.

            "Reference U.S. Treasury Dealer" means each of J.P. Morgan
Securities Inc. and Salomon Smith Barney Inc., and two other treasury dealers
selected by the Company, and their respective successors; provided, however,
that if any of the foregoing shall cease to be a primary U.S. Government
securities dealer (a "Primary Treasury Dealer"), the Company shall substitute
therefor another nationally recognized investment banking firm that is a Primary
Treasury Dealer.

            "Reference U.S. Treasury Dealer Quotations" means, with respect to
each Reference U.S. Treasury Dealer and any Redemption Date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference U.S. Treasury Dealer at 3:30
p.m., New York City time on the third Business Day preceding such Redemption
Date.

            "Remaining Scheduled Payments" means, with respect to each Note to
be redeemed, the remaining scheduled payments of the principal thereof and
interest thereon that would be due after the related Redemption Date but for
such redemption; provided, however, that, if such Redemption Date is not an
Interest Payment Date with respect to such Note, the amount of the next
succeeding scheduled interest payment thereon will be reduced by the amount of
interest accrued thereon to such Redemption Date.

            "Treasury Rate" means, with respect to any Redemption Date, (i) the
yield, under the heading which represents the average for the immediately
preceding week, appearing in the most recently published statistical release
designated "H.15(519)" or any successor publication which is published weekly by
the Board of Governors of the Federal Reserve System and which establishes
yields on actively traded United States Treasury securities

<PAGE>

adjusted to constant maturity under the caption "Treasury Constant Maturities,"
for the maturity corresponding to the Comparable Treasury Issue, provided that
if no maturity is within three months before or after the maturity date for the
Notes, yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue will be determined and the Treasury Rate will be
interpolated or extrapolated from those yields on a straight line basis,
rounding to the nearest month; or (ii) if that release, or any successor
release, is not published during the week preceding the calculation date or does
not contain such yields, the rate per annum equal to the semiannual equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for that Redemption Date. The
Treasury Rate will be calculated on the third Business Day preceding the
Redemption Date.

            PAYMENT OF ADDITIONAL AMOUNTS. The Company will, subject to certain
exceptions and limitations set forth below, pay such Additional Amounts to the
beneficial owner of this Note who is a Non-U.S. Holder (as defined below) as may
be necessary in order that every net payment of principal of and interest on
such Note and any other amounts payable on such Note, after withholding for or
on account of any present or future tax, assessment or governmental charge
imposed upon or as a result of such payment by the United States (or any
political subdivision or taxing authority thereof or therein), will not be less
than the amount provided for in this Note to be then due and payable. The
Company will not, however, be required to make any such payment of Additional
Amounts to any beneficial owner for or on account of:

            (a) any such tax, assessment or other governmental charge that would
      not have been so imposed or withheld but for the existence of any present
      or former connection between such beneficial owner (or between a
      fiduciary, settlor, beneficiary, member or shareholder of such beneficial
      owner, if such beneficial owner is an estate, a trust, a partnership or a
      corporation) and the United States and its possessions, including, without
      limitation, such beneficial owner (or such fiduciary, settlor,
      beneficiary, member or shareholder) being or having been a citizen or
      resident thereof or being or having been engaged in a trade or business or
      present therein or having, or having had, a permanent establishment
      therein;

            (b) any estate, inheritance, gift, sales, transfer or personal
      property tax or any similar tax, assessment or governmental charge;

            (c) any tax, assessment or other governmental charge imposed or
      withheld by reason of such beneficial owner's past or present status as a
      personal holding company or foreign personal holding company or controlled
      foreign corporation or passive foreign investment company with respect to
      the United States or as a corporation that accumulates earnings to avoid
      United States federal income tax;

            (d) any tax, assessment or other governmental charge that is payable
      otherwise than by withholding from payments on or in respect of this Note;

            (e) any tax, assessment or other governmental charge that would not
      have been imposed or withheld but for the failure to comply with
      certification, information or other reporting requirements concerning the
      nationality, residence or identity of the beneficial owner of this Note,
      if such compliance is required by

<PAGE>

      statute or by regulation of the United States or of any political
      subdivision or taxing authority thereof or therein or by an applicable
      income tax treaty to which the United States is a party as a precondition
      to relief or exemption from such tax, assessment or other governmental
      charge;

            (f) any tax, assessment or other governmental charge imposed or
      withheld by reason of such beneficial owner's past or present status as
      the actual or constructive owner of 10% or more of the total combined
      voting power of all classes of the Company's stock entitled to vote or as
      a controlled foreign corporation that is related directly or indirectly to
      the Company through stock ownership;

            (g) to the extent applicable, any tax, assessment or governmental
      charge that is imposed or withheld solely because of a change in law,
      regulation, or administrative or judicial interpretation that becomes
      effective more than 15 days after the payment becomes due or is duly
      provided for, whichever occurs later;

            (h) any tax, assessment or governmental charge any Paying Agent must
      withhold from any payment of principal of or interest on any note, if such
      payment can be made without such withholding by any other Paying Agent; or

            (i) any combination of clauses (a) through (h) above.

            Such Additional Amounts shall also not be paid with respect to any
payment on this Note to a Non-U.S. Holder who is a fiduciary or partnership or
other than the sole beneficial owner of such payment to the extent such payment
would be required by the laws of the United States (or any political subdivision
thereof) to be included in the income, for tax purposes, of a beneficiary or
settlor with respect to such fiduciary or a member of such partnership or a
beneficial owner who would not have been entitled to such Additional Amounts had
such beneficiary, settlor, member or beneficial owner, as the case my be, held
its interest in this Note directly.

            The term "Non-U.S. Holder" means any person that is, for United
States federal income tax purposes, (i) an individual that is not a citizen or
resident of the U.S., (ii) a corporation organized or created under non-U.S.
law, (iii) an estate or trust that is not subject to U.S. federal income tax on
its worldwide income, or (iv) a foreign partnership to the extent that one or
more of its members is a foreign corporation, a nonresident alien individual or
a nonresident alien fiduciary of a foreign estate or trust.

            The Notes are subject in all cases to any tax, fiscal or other law
or regulation or administrative or judicial interpretation applicable. Except as
specifically provided herein the Company does not have to make any payment with
respect to any tax, assessment or governmental charge imposed by any government
or a political subdivision or taxing authority.

            All references to payments of principal, premium, if any, or
interest in respect of the Notes are deemed to include Additional Amounts if
any.

            TAX REDEMPTION. This Note may be redeemed as a whole, at the
Company's option at any time prior to maturity, upon the giving of a notice of
redemption as described

<PAGE>

below, if (a) the Company determines that, as a result of any change in or
amendment to the laws (or any regulations or rulings promulgated thereunder) of
the United States or of any political subdivision or taxing authority thereof or
therein, or any change in official position regarding the application or
interpretation of such laws, regulations or rulings, which change or amendment
becomes effective on or after June 28, 2001, the Company has or will become
obligated to pay Additional Amounts as described in the preceding Section
entitled "Payment of Additional Amounts" or (b) a taxing authority of the United
States takes an action on or after June 28, 2001 whether or not with respect to
the Company or any of its Affiliates (as defined in the Indenture) that results
in a substantial probability that the Company will or my be required to pay such
Additional Amounts, in either case, with respect to this Note for reasons
outside its control and after taking reasonable measures to avoid such
obligation. The Notes will be redeemed at a redemption price equal to 100% of
the principal amount thereof, together with accrued interest to the date fixed
for redemption. Prior to the giving of any notice of redemption pursuant to this
paragraph, the Company will deliver to the Trustee:

            (a) an Officer's Certificate (as defined in the Indenture) stating
      that the Company is entitled to effect such redemption and setting forth a
      statement of facts showing that the conditions precedent to its right to
      so redeem have occurred, and

            (b) an Opinion of Counsel (as defined in the Indenture) who is
      independent satisfactory to the Trustee to the effect that the Company has
      or will become obligated or there is a substantial probability that the
      Company will or may be required to pay such Additional Amounts for the
      reasons described above;

      provided that no such notice of redemption pursuant to this paragraph
      entitled "Tax Redemption" shall be given earlier than 60 days prior to the
      earliest date on which the Company would be obligated to pay such
      Additional Amounts if a payment in respect of the Note were then due.

            Notice of redemption pursuant to the preceding paragraph entitled
"Tax Redemption" will be given not less than 30 nor more than 60 days prior to
the date fixed for redemption, which date and the applicable redemption price
will be specified in the notice.

            REGISTRATION RIGHTS. The Company shall enter into a registration
rights agreement (the "Registration Agreement") with the holder of this Note in
the form of Exhibit A to this Note concurrently with the delivery of this Note.
Capitalized terms used in this paragraph but not defined herein have the
meanings assigned to them in the form of Registration Agreement attached hereto
as Exhibit A. If (i) the Exchange Offer Registration Statement is not filed with
the Commission on or prior to 90 days after the date this Note was issued to the
holder hereof (the "Issue Date"), (ii) the Exchange Offer Registration Statement
is not declared effective within 180 days after the Issue Date, or (iii) the
Registered Exchange Offer is not consummated or the Shelf Registration Statement
is not declared effective on or prior to 210 days after the Issue Date (each
such event referred to in clauses (i) through (iii), a "REGISTRATION DEFAULT"),
the Company will be obligated to pay liquidated damages to each Holder of
Transfer Restricted Securities, during the period of one or more such
Registration Defaults, in an amount equal to $0.192 per week per $1,000
principal amount of Transfer Restricted Securities held by

<PAGE>

such Holder until (i) the Exchange Offer Registration Statement is filed, (ii)
the Exchange Offer Registration Statement is declared effective or (iii) the
Registered Exchange Offer is consummated or the Shelf Registration Statement is
declared effective, as the case may be. Following the cure of all Registration
Defaults, the accrual of liquidated damages will cease. In addition, if the
Shelf Registration Statement is declared effective within 210 days after the
Issue Date, and the Company fails to keep the Shelf Registration Statement
continuously (x) effective or (y) useable for resales of the Transfer Restricted
Securities for the period required by Section 2(b) of the Registration Rights
Agreement, and such failure continues for more than 60 days (whether or not
consecutive) in any 12-month period (the 61st day being referred to as the
"DEFAULT DAY"), then from the Default Day until the earlier of (i) the date that
the Shelf Registration Statement is again deemed effective or is usable, (ii)
the date that is the second anniversary of the Issue Date (or, if Rule 144(k) is
amended to provide a shorter restrictive period, such shorter period) or (iii)
the date as of which all of the Transfer Restricted Securities are sold pursuant
to the Shelf Registration Statement, liquidated damages in respect of the
Transfer Restricted Securities shall accrue at a rate equal to $.192 per week
per $1,000 principal amount of Transfer Restricted Securities. All references to
payments of interest are deemed to include the additional interest payable in
respect of a Registration Default or after a Default Day, as applicable.

            MODIFICATION. The Indenture permits, with certain exceptions as
thereby provided, the Trustee to enter into one or more supplemental indentures
for the purpose of adding any provisions to, or changing in any manner or
eliminating any of the provisions of, the Indenture or of modifying in any
manner the rights of the Holders of Securities, in any such case, with the
consent of the Holders of not less than majority in aggregate principal amount
of all Outstanding Securities affected by such supplemental indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each of the Outstanding Securities affected thereby, affect certain
rights of such Holders as more fully described in the Indenture.

            The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities then Outstanding, on
behalf of the Holders of all Securities affected thereby, to waive certain past
defaults of the Company under the Indenture and their consequences. In addition,
without the consent of any Holder of a Security, the Indenture and the
Securities may be amended and supplemented to cure any defect, ambiguity or
inconsistency, make other changes which will not adversely affect in any
material respect the rights of the Holders or certain other matters specified in
the Indenture. Any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange
here for or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Note.

            As provided in and subject to the provisions of the Indenture, the
Holder of this Note shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee, or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25 percent in principal amount of the Notes
Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity and the Trustee shall not have received from the
Holders of

<PAGE>

a majority in principal amount of the Notes Outstanding a direction inconsistent
with such request, and shall have failed to institute any such proceeding, for
60 days after receipt of such notice, request and offer of indemnity. The
foregoing shall not apply to certain suits described in the Indenture, including
any suit instituted by the Holder of this Note for the enforcement of any
payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein (or, in the case of redemption, on or
after the Redemption Date).

            No reference herein to the Indenture and no provision of this Note
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 Note at the times, place and rate, in the coin or
currency, and in the manner, herein prescribed.

            The Notes are issuable only in registered forth, without coupons, in
denominations of $1,000 and any integral multiple of $1,000. The Notes may be
represented by one or more global Notes deposited with DTC and registered in the
name of the nominee of DTC, with certain limited exceptions. So long as DTC or
any successor depository or its nominee is the registered Holder of a global
Note, DTC, such depository or such nominee, as the case may be, will be
considered to be the sole Holder of the Notes for all purposes of the Indenture.
Except as provided below, an owner of a beneficial interest in a global Note
will not be entitled to have Notes represented by such global Note registered in
such owner's name, will not receive or be entitled to receive physical delivery
of the Notes in certificated form and will not be considered the owner or Holder
thereof under the Indenture. Each person owning a beneficial interest in a
global Note must rely on DTC's procedures and, if such person is not a
participant, on the procedures of the participant through which such person owns
its interest, to exercise any rights of a Holder under the Indenture. If the
Company requests any action of Holders or if an owner of a beneficial interest
in a global Note desires to take any action that a Holder is entitled to take
under the Indenture, DTC will authorize the participants holding the relevant
beneficial interests to give or take such action, and such participants will
otherwise act upon the instructions of beneficial owners holding through them.

            If at any time DTC notifies the Company that it is unwilling or
unable to continue as depository for the global Note or Notes or if at any time
DTC ceases to be a clearing agency registered under the Securities Exchange Act
of 1934, as amended, if so required by applicable law or regulation, the Company
shall appoint a successor depository with respect to such global Note or Notes.
If (x) a successor depository for such global Note or Notes is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such unwillingness, inability or ineligibility, (y) an Event of Default
has occurred and is continuing and a beneficial owner representing a majority in
principal amount of the Notes represented by such global Note or Notes advise
DTC to cease acting as depository for such global Note or Notes or (z) the
Company, in its sole discretion, determines at any time that all Outstanding
Notes (but not less than all) issued or issuable in the form of one or more
global Notes shall no longer be represented by such global Notes, then the
Company shall execute, and the Trustee shall authenticate and deliver,
definitive Notes of like series, rank, tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such global Note or
Notes. If any beneficial owner of an interest in a permanent global Note is
otherwise entitled to exchange such interest for Notes of such series and of
like tenor and principal amount of

<PAGE>

another authorized form and denomination, as contemplated by the Indenture and
provided that any applicable notice provided in the permanent global Note shall
have been given, then without unnecessary delay but in any event not later than
the earliest date on which such interest may be so exchanged, the Company shall
execute, and the Trustee shall authenticate and deliver, definitive Notes in
aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent global Note. On or after the earliest date on
which such interests may be so exchanged, such permanent global Note shall be
surrendered for exchange by DTC or such other depository as the Company shall
specify to the Trustee; PROVIDED, HOWEVER, that no such exchanges may occur
during a period beginning at the opening of business 15 days before any
selection of Notes to be redeemed and ending on the relevant Redemption Date if
the Note for which exchange is requested may be among those selected for
redemption.

            Initially, the Trustee will be the Security Registrar and Paying
Agent for this Note. The Company reserves the rights at any time to remove any
Paying Agent, Transfer Agent or Security Registrar without notice, to appoint
additional or other Paying Agents, other Transfer Agents and other Security
Registrars without notice and to approve any change in the office through which
any Paying Agent, Transfer Agent or Security Registrar acts. None of the
Company, the Trustee, any Paying Agent or the Security Registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Note in global
form or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee, or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by any depository, as a Holder, with respect to this
Note in global form or impair, as between such depository and owners of
beneficial interests in such global Note, the operation of customary practices
governing the exercise of the rights of such depository (or its nominee) as
Holder of such global Note.

            THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
CONFLICTS OF LAW PRINCIPLES THEREOF.

            As used herein, "Business Day," means each day other than a
Saturday, Sunday or a day on which commercial banking institutions are
authorized or required by law to close in New York City.

            The Company may cause CUSIP or ISIN numbers to be printed on the
Notes as a convenience to Holders of Notes. No representation is made as to the
accuracy of such numbers as printed on the Notes, and reliance may be placed
only on the other identification numbers printed thereon.

            This Note shall not be entitled to any benefit under the Indenture
or be valid or obligatory until the Trustee or authenticating agent signs the
certificate of authenticity on the Notes.

            No recourse shall be had for the payment of the principal of (or
premium, if any) or interest, if any, or Additional Amounts, if any, on this
Note, or any part hereof, or for

<PAGE>

any claim based hereon or otherwise in respect hereof, or of the indebtedness
represented hereby, or upon any obligation, covenant or agreement under the
Indenture, against, and no personal liability whatsoever shall attach to, or be
incurred by, any incorporator, shareholder, officer or director, as such, past,
present or future, of (i) the Company or (ii) any predecessor or successor
corporation (either directly or through the Company or a predecessor or
successor corporation), whether by virtue of any constitutional provision,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly agreed and understood that the Indenture and all
of the Notes are solely corporate obligations and that any such personal
liability is hereby expressly waived and released as a condition of, and as part
of the consideration for, the execution of the Indenture and the issuance of the
Notes.

[NAME]

[CITY, STATE, ZIP CODE]

Ladies and Gentlemen:

            WorldCom, Inc., a Georgia corporation (the "COMPANY"), proposes to
issue to [ ] (each a "HOLDER"), $[ ] aggregate principal amount of its 7.69%
Notes Due 2009 (the "SECURITIES") issued under the indenture dated as of May 15,
2000 (the "INDENTURE"), between the Company and Chase Manhattan Trust Company,
National Association (the "TRUSTEE"). In order to induce each Holder to acquire
the Securities, the Securities require that the Company enter into this
Agreement with each Holders. For good and valid consideration, the receipt and
sufficiency of which is acknowledged by the parties hereto, the parties agree as
follows:

1.    REGISTERED EXCHANGE OFFER. The Company shall (i) use its reasonable best
      efforts to prepare and, not later than 90 days following the date of
      original issuance of the Securities (the "ISSUE DATE"), 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, and the rules and
      regulations of the Commission promulgated thereunder (the "SECURITIES
      ACT") with respect to a proposed offer to the Holders of the Securities
      (the "REGISTERED EXCHANGE OFFER") to issue and deliver to such Holders, in
      exchange for the Securities, a like aggregate principal amount of debt
      securities of the Company (the "EXCHANGE SECURITIES") that are identical
      in all material respects to the Securities, except for the transfer
      restrictions relating to the Securities, (ii) use its reasonable best
      efforts to cause the Exchange Offer Registration Statement to become
      effective under the Securities Act no later than 180 days after the date
      on which the Securities were issued (the "ISSUE DATE") and the Registered

                                       2
<PAGE>

      Exchange Offer to be consummated no later than 210 days after the Issue
      Date and (iii) keep the Exchange Offer Registration Statement effective
      for not less than 20 business days (or longer, if required by applicable
      law) after the date on which notice of the Registered Exchange Offer is
      mailed to the Holders (such period being called the "EXCHANGE OFFER
      REGISTRATION Period"). The Exchange Securities will be issued under the
      Indenture.

            Upon the effectiveness of the Exchange Offer Registration Statement,
the Company shall promptly commence the Registered Exchange Offer, it being the
objective of such Registered Exchange Offer to enable each Holder electing to
exchange Securities for Exchange Securities (assuming that such Holder (a) is
not an affiliate of the Company or an Exchanging Dealer (as defined herein) not
complying with the requirements of the next sentence, (b) is not holding
Securities that have, or that are reasonably likely to have, the status of an
unsold allotment in an initial distribution, (c) acquires the Exchange
Securities in the ordinary course of such Holder's business and (d) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Securities) and to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of
the several states of the United States. The Company, each Holder and each
Exchanging Dealer acknowledge that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, each Holder that is a
broker-dealer electing to exchange 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 substantially 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 such prospectus in connection with a sale of any such
Exchange Securities received by such Exchanging Dealer pursuant to the
Registered Exchange Offer.

            If, prior to the consummation of the Registered Exchange Offer, any
Holder holds any Securities acquired by it that have, or that are reasonably
likely to be determined to have, the status of an unsold allotment in an initial
distribution, or any Holder is not entitled to participate in the Registered
Exchange Offer, the Company shall, upon the request of any such Holder,
simultaneously with the delivery of the Exchange Securities in the Registered
Exchange Offer, issue and deliver to any such Holder, in exchange for the
Securities held by such Holder (the "PRIVATE EXCHANGE"), a like aggregate
principal amount of debt securities of the Company (the "PRIVATE EXCHANGE
SECURITIES") that are identical in all material respects to the Exchange
Securities, except for the transfer restrictions relating to such Private
Exchange Securities. The Private Exchange Securities will be issued under the
same indenture as the Exchange Securities, and the Company shall use its
reasonable best efforts to cause the Private Exchange Securities to bear the
same CUSIP number as any Exchange Securities.

            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

                                       3
<PAGE>

            transmittal and related documents;

            b. keep the Registered Exchange Offer open for not less than 20
            business days (or longer, if required by applicable law) after the
            date on which notice of the Registered Exchange Offer 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;

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

            e. otherwise comply in all respects with all laws that are
            applicable to the Registered Exchange Offer.

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

            a. accept for exchange all Securities tendered and not validly
            withdrawn pursuant to the Registered Exchange Offer and the Private
            Exchange;

            b. deliver to the Trustee for cancellation all Securities so
            accepted for exchange; and

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

            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 used 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 that (i) in the case where
such prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer, such period shall be the lesser of 180 days and the date on
which all Exchanging Dealers have sold all Exchange Securities held by them 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 90 days after the
consummation of the Registered Exchange Offer.

            The Indenture shall provide that the Securities, the Exchange
Securities and the Private Exchange Securities shall vote and consent together
on all matters as one class and that none of the Securities, the Exchange
Securities or the Private Exchange Securities will have the right to vote or
consent as a separate class on any matter.

                                       4
<PAGE>

            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 Securities surrendered in exchange therefor or, if no interest has been paid
on the Securities, from the Issue Date.

            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 business, (ii) such Holder will have
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 and (iii) such Holder is not an affiliate of the Company or,
if it is such an affiliate, such Holder will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.

            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 of the
Commission 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, as of the consummation of the
Registered Exchange Offer, include an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

2.    SHELF REGISTRATION. If (i) because of any change in law or applicable
      interpretations thereof by the Commission's staff the Company is not
      permitted to effect the Registered Exchange Offer as contemplated by
      Section 1 hereof, or (ii) any Securities validly tendered pursuant to the
      Registered Exchange Offer are not exchanged for Exchange Securities within
      210 days after the Issue Date, or (iii) any Holder so requests with
      respect to Securities or Private Exchange Securities not eligible to be
      exchanged for Exchange Securities in the Registered Exchange Offer and
      held by it following the consummation of the Registered Exchange Offer, or
      (iv) any applicable law or interpretations do not permit any Holder to
      participate in the Registered Exchange Offer, or (v) any Holder that
      participates in the Registered Exchange Offer does not receive freely
      transferable Exchange Securities in exchange for tendered Securities, or
      (vi) the Company so elects, then the following provisions shall apply:

      a.    The Company shall use its reasonable best efforts to file as
      promptly as practicable (but in no event more than 60 days after so
      required or requested pursuant to this Section 2) with the Commission, and
      thereafter shall use its commercially reasonable efforts to cause to be
      declared effective, a shelf registration statement on an appropriate form
      under the Securities Act relating to the offer and sale of the Transfer
      Restricted Securities (as defined below) by the

                                       5
<PAGE>

      Holders thereof from time to time in accordance with the methods of
      distribution set forth in such registration statement (hereafter, a "SHELF
      REGISTRATION STATEMENT" and, together with any Exchange Offer Registration
      Statement, a "REGISTRATION STATEMENT").

      b.    The Company shall use its reasonable best efforts to keep the Shelf
      Registration Statement continuously effective in order to permit the
      prospectus forming part thereof to be used by Holders of Transfer
      Restricted Securities for a period ending on the earlier of (i) two years
      from the Issue Date or such shorter period that will terminate when all
      the Transfer Restricted Securities covered by the Shelf Registration
      Statement have been sold pursuant thereto and (ii) the date on which the
      Securities become eligible for resale without volume restrictions pursuant
      to Rule 144 under the Securities Act (in any such case, such period being
      called the "SHELF REGISTRATION PERIOD"); PROVIDED, HOWEVER, that the
      Company shall in no event be obligated to keep such Shelf Registration
      Statement effective for a period of more than 270 days from the date the
      Shelf Registration Statement is declared effective by the Commission if
      the Shelf Registration Statement is required to be filed solely to permit
      resales by a broker-dealer that holds Securities acquired directly from
      the Company or one or more of its affiliates or such shorter period that
      will terminate when all such Securities cease to be Transfer Restricted
      Securities; PROVIDED, FURTHER, that, during any consecutive 365-day
      period, the Company may suspend the effectiveness of the Shelf
      Registration Statement for an aggregate period of not more than 60
      consecutive days if there is a possible acquisition or business
      combination or other transaction, business development or event involving
      the Company that would require disclosure in the Shelf Registration
      Statement and the Company determines in the exercise of its reasonable
      judgment that such disclosure is not in the best interests of the Company
      and its stockholders or obtaining any financial statements relating to an
      acquisition or business combination required to be included in the Shelf
      Registration Statement would be impracticable. In the event that the
      Company suspends the effectiveness of the Shelf Registration Statement as
      contemplated by the final proviso to the foregoing sentence, the Company
      shall promptly notify the Holders of such suspension, PROVIDED that such
      notice shall not require the Company to disclose the possible acquisition
      or business combination or other transaction, business development or
      event if the Company determines that such acquisition or business
      combination or other transaction, business development or event should
      remain confidential. Upon the abandonment, consummation, termination or
      public announcement by or on behalf of the Company of the possible
      acquisition or business combination or other transaction, business
      development or event or the availability of the required financial
      statements with respect to a possible acquisition or business combination,
      the suspension of the use of the Shelf Registration Statement shall cease
      and the Company shall promptly comply with Section 4(j) hereof and notify
      the Holders that disposition of Transfer Restricted Securities may resume.
      The Company shall be deemed not to have used its commercially reasonable
      efforts to keep the Shelf Registration Statement effective during the
      requisite period if it voluntarily takes any action that would result in
      Holders of Transfer Restricted Securities covered thereby not being able
      to offer and sell such Transfer Restricted Securities during that period,

                                       6
<PAGE>

      unless such action is required by applicable law.

      c.    Notwithstanding any other provisions hereof, the Company will ensure
      that (i) any Shelf 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 of the Commission thereunder, (ii) any Shelf Registration
      Statement and any amendment thereto (in either case, other than with
      respect to information included therein in reliance upon or in conformity
      with written information furnished to the Company by or on behalf of any
      Holder specifically for use therein (the "HOLDERS' INFORMATION")) does 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 (iii) any prospectus
      forming part of any Shelf Registration Statement, and any supplement to
      such prospectus (in either case, other than with respect to Holders'
      Information), does not include an untrue statement of a material fact or
      omit to state a material fact necessary in order to make the statements
      therein, in the light of the circumstances under which they were made, not
      misleading.

3.    LIQUIDATED DAMAGES. (a) The parties hereto agree that the Holders of
      Transfer Restricted Securities will suffer damages if the Company fails to
      fulfill its obligations under Section 1 or Section 2, as applicable, and
      that it would not be feasible to ascertain the extent of such damages.
      Accordingly, if (i) the Exchange Offer Registration Statement is not filed
      with the Commission on or prior to 90 days after the Issue Date, (ii) the
      Exchange Offer Registration Statement is not declared effective within 180
      days after the Issue Date, or (iii) the Registered Exchange Offer is not
      consummated or the Shelf Registration Statement is not declared effective
      on or prior to 210 days after the Issue Date (each such event referred to
      in clauses (i) through (iii), a "REGISTRATION DEFAULT"), the Company will
      be obligated to pay liquidated damages to each Holder of Transfer
      Restricted Securities, during the period of one or more such Registration
      Defaults, in an amount equal to $0.192 per week per $1,000 principal
      amount of Transfer Restricted Securities held by such Holder until (i) the
      Exchange Offer Registration Statement is filed, (ii) the Exchange
      Offer-Registration Statement is declared effective or (iii) the Registered
      Exchange Offer is consummated or the Shelf Registration Statement is
      declared effective, as the case may be. Following the cure of all
      Registration Defaults, the accrual of liquidated damages will cease. As
      used herein, the term "TRANSFER RESTRICTED SECURITIES" means (i) each
      Security until the date on which such Security has been exchanged for a
      freely transferable Exchange Security in the Registered Exchange Offer,
      (ii) each Security or Private Exchange Security until the date on which it
      has been effectively registered under the Securities Act and disposed of
      in accordance with the Shelf Registration Statement or (iii) each Security
      or Private Exchange Security until the date on which it 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. Notwithstanding anything
      to the contrary in this Section 3(a), the Company shall not be required to
      pay liquidated damages to a Holder of Transfer Restricted Securities if
      such Holder failed to comply with its obligations to make the
      representations set forth in the second to last paragraph of Section 1 or
      failed to

                                       7
<PAGE>

      provide the information required to be provided by it, if any, pursuant to
      Section 4(n).

            In addition, if the Shelf Registration Statement is declared
effective pursuant to Section 2, and the Company fails to keep the Shelf
Registration Statement continuously (x) effective or (y) useable for resales of
the Transfer Restricted Securities for the period required by Section 2(b), and
such failure continues for more than 60 days (whether or not consecutive) in any
12-month period (the 61st day being referred to as the "DEFAULT DAY"), then from
the Default Day until the earlier of (i) the date that the Shelf Registration
Statement is again deemed effective or is usable, (ii) the date that is the
second anniversary of the Issue Date (or, if Rule 144(k) is amended to provide a
shorter restrictive period, such shorter period) or (iii) the date as of which
all of the Transfer Restricted Securities are sold pursuant to the Shelf
Registration Statement, liquidated damages in respect of the Transfer Restricted
Securities shall accrue at a rate equal to $.192 per week per $1,000 principal
amount of Transfer Restricted Securities.

            (b) The Company shall notify the Trustee and the paying agent under
the Indenture immediately upon the happening of each and every Registration
Default. The Company shall pay the liquidated damages due on the Transfer
Restricted Securities by depositing with the Paying Agent (which may not be the
Company for these purposes), in trust, for the benefit of the Holders thereof,
prior to 10:00 a.m., New York City time, on the next interest payment date
specified by the Indenture and the Securities, sums sufficient to pay the
liquidated damages then due. The liquidated damages due shall be payable on each
interest payment date specified by the Securities to the record holder entitled
to receive the interest payment to be made on such date. Each obligation to pay
liquidated damages shall be deemed to accrue from and including the date of the
applicable Registration Default.

            (c) The parties hereto agree that the liquidated damages provided
for in this Section 3 constitute a reasonable estimate of and are intended to
constitute the sole damages that will be suffered by Holders of Transfer
Restricted Securities by reason of the failure of (i) the Shelf Registration
Statement or the Exchange Offer Registration Statement to be filed, (ii) the
Shelf Registration Statement to remain effective or (iii) the Exchange Offer
Registration Statement to be declared effective and the Registered Exchange
Offer to be consummated, in each case to the extent required by this Agreement.

4.    REGISTRATION PROCEDURES. In connection with any Registration Statement,
      the following provisions shall apply:

      a.    The Company shall (i) furnish to each Holder, prior to the filing
            thereof with the Commission, a copy of the Registration Statement
            and each amendment thereof and each supplement, if any, to the
            prospectus included therein and shall use its reasonable best
            efforts to reflect in each such document, when so filed with the
            Commission, such comments as any Holder may reasonably propose; (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

                                       8
<PAGE>

            the information set forth in Annex D hereto in the Letter of
            Transmittal delivered pursuant to the Registered Exchange Offer; and
            (iii) if requested by any Holder, include the information required
            by Items 507 or 508 of Regulation S-K, as applicable, in the
            prospectus forming a part of the Exchange Offer Registration
            Statement.

      b.    The Company shall advise each Holder and each Exchanging Dealer and,
            if requested by any such person, confirm such advice in writing
            (which advice 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 any Registration Statement and any amendment thereto
                  has been filed with the Commission and when such Registration
                  Statement or any post-effective amendment thereto has become
                  effective;

                  ii. of any request by the Commission for amendments or
                  supplements to any 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 any Registration Statement or
                  the initiation of any proceedings for that purpose;

                  iv. of the receipt by the Company of any notification with
                  respect to the suspension of the qualification of the
                  Securities, the Exchange Securities or the Private Exchange
                  Securities for sale in any jurisdiction or the initiation or
                  threatening of any proceeding for such purpose; and

                  v. of the happening of any event that requires the making of
                  any changes in any Registration Statement or the prospectus
                  included therein in order that the statements therein are not
                  misleading and do not omit to state a material fact required
                  to be stated therein or necessary to make the statements
                  therein not misleading.

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

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

      e.    The Company will, during the Shelf Registration Period, promptly
            deliver to each Holder of Transfer Restricted Securities included
            within the coverage of any Shelf Registration Statement, without
            charge, as many copies of

                                       9

            the prospectus (including each preliminary prospectus) included in
            such Shelf Registration Statement and any amendment or supplement
            thereto as such Holder may reasonably request; and the Company
            consents to the use of such prospectus or any amendment or
            supplement thereto by each of the selling Holders of Transfer
            Restricted Securities in connection with the offer and sale of the
            Transfer Restricted Securities covered by such prospectus or any
            amendment or supplement thereto.

      f.    The Company will furnish to each Holder and each Exchanging Dealer,
            without charge, at least one conformed copy of the Exchange Offer
            Registration Statement and any post-effective amendment thereto,
            including financial statements and schedules and, if any Holder or
            Exchanging Dealer or any such Holder so requests in writing, all
            exhibits thereto (including those, if any, incorporated by
            reference).

      g.    The Company will, during the Exchange Offer Registration Period or
            the Shelf Registration Period, as applicable, promptly deliver to
            each Holder, each Exchanging Dealer and such other persons that are
            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 or the Shelf
            Registration Statement and any amendment or supplement thereto as
            such Holder, Exchanging Dealer or other persons may reasonably
            request; and the Company consents to the use of such prospectus or
            any amendment or supplement thereto by any such Holder, Exchanging
            Dealer or other persons, as applicable, as aforesaid.

      h.    Prior to the effective date of any Registration Statement, the
            Company will use its reasonable best efforts to register or qualify,
            or cooperate with the Holders of Securities, Exchange Securities or
            Private Exchange Securities included therein and their respective
            counsel in connection with the registration or qualification of,
            such Securities, Exchange Securities or Private Exchange Securities
            for offer and sale under the securities or blue sky laws of such
            jurisdictions as any such Holder reasonably requests in writing and
            do any and all other acts or things necessary or advisable to enable
            the offer and sale in such jurisdictions of the Securities, Exchange
            Securities or Private Exchange Securities covered by such
            Registration Statement; PROVIDED that the Company will not be
            required to qualify -------- generally to do business in any
            jurisdiction where it is not then so qualified or to take any action
            which would subject it to general service of process or to taxation
            in any such jurisdiction where it is not then so subject.

      i.    The Company will cooperate with the Holders of Securities, Exchange
            Securities or Private Exchange Securities to facilitate the timely
            preparation and delivery of certificates representing Securities,
            Exchange Securities or Private Exchange 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 thereof may request in writing prior to sales of
            Securities, Exchange Securities or Private Exchange Securities
            pursuant to such Registration Statement.

                                       10

      j.    If any event contemplated by Section 4(b)(ii) through (v) occurs
            during the period for which the Company is required to maintain an
            effective Registration Statement, the Company will promptly prepare
            and file with the Commission a post-effective amendment to the
            Registration Statement or a supplement to the related prospectus or
            file any other required document so that, as thereafter delivered to
            purchasers of the Securities, Exchange Securities or Private
            Exchange Securities from a Holder, the prospectus will not include
            an untrue statement of a material fact or omit to state a material
            fact necessary in order to make the statements therein, in the light
            of the circumstances under which they were made, not misleading.

      k.    Not later than the effective date of the applicable Registration
            Statement, the Company will provide a CUSIP number for the
            Securities, the Exchange Securities and the Private Exchange
            Securities, as the case may be, and provide the applicable trustee
            with printed certificates for the 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.

      l.    The Company will comply with all applicable rules and regulations of
            the Commission and will make generally available to its security
            holders as soon as practicable after the effective date of the
            applicable Registration Statement an earning statement satisfying
            the provisions of Section 11(a) of the Securities Act; PROVIDED that
            in no event shall such earning statement be delivered 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
            applicable Registration Statement, which statement shall cover such
            12-month period.

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

      n.    In the case of a Shelf Registration Statement, each Holder of
            Transfer Restricted Securities to be registered pursuant thereto
            agrees by acquisition of such Transfer Restricted Securities that,
            upon receipt of any notice from the Company pursuant to Section
            4(b)(ii) through (v), such Holder will discontinue disposition of
            such Transfer Restricted Securities until such Holder's receipt of
            copies of the supplemental or amended prospectus contemplated by
            Section 4(j) or until advised in writing (the "ADVICE") by the
            Company that the use of the applicable prospectus may be resumed. If
            the Company shall give any notice under Section 4(b)(ii) through (v)
            during the period that the Company is required to maintain an
            effective Registration Statement (the "EFFECTIVENESS PERIOD"), such
            Effectiveness Period shall be extended by the number of days during
            such period from and

                                       11
<PAGE>

            including the date of the giving of such notice to and including the
            date when each seller of Transfer Restricted Securities covered by
            such Registration Statement shall have received (x) the copies of
            the supplemental or amended prospectus contemplated by Section 4(j)
            (if an amended or supplemental prospectus is required) or (y) the
            Advice (if no amended or supplemental prospectus is required).

      o.    In the case of a Shelf Registration Statement, 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 Holders of a majority in aggregate principal
            amount of the Securities, Exchange Securities and Private Exchange
            Securities being sold or the managing underwriters (if any) shall
            reasonably request in order to facilitate any disposition of
            Securities, Exchange Securities or Private Exchange Securities
            pursuant to such Shelf Registration Statement.

      p.    In the case of a Shelf Registration Statement, the Company shall (i)
            make reasonably available for inspection by a representative of, and
            Special Counsel (as defined below) acting for, Holders of a majority
            in aggregate principal amount of the Securities, Exchange Securities
            and Private Exchange Securities being sold and any underwriter
            participating in any disposition of Securities, Exchange Securities
            or Private Exchange Securities pursuant to such Shelf Registration
            Statement, all relevant financial and other records, pertinent
            corporate documents and properties of the Company and its
            subsidiaries to the same extent that the Company would customarily
            make such information available in the context of due diligence for
            an underwritten public offering and (ii) use its reasonable best
            efforts to have its officers, directors, employees, accountants and
            counsel supply all relevant information reasonably requested by such
            representative, Special Counsel or any such underwriter (an
            "INSPECTOR") in connection with the preparation of such Shelf
            Registration Statement.

      q.    In the case of a Shelf Registration Statement, the Company shall, if
            requested by Holders of a majority in aggregate principal amount of
            the Securities, Exchange Securities and Private Exchange Securities
            being sold, their Special Counsel or the managing underwriters (if
            any) in connection with such Shelf Registration Statement, use its
            reasonable best efforts to cause (i) its counsel to deliver an
            opinion relating to the Shelf Registration Statement and the
            Securities, Exchange Securities or Private Exchange Securities, as
            applicable, in customary form, (ii) its officers to execute and
            deliver all customary documents and certificates requested by
            Holders of a majority in aggregate principal amount of the
            Securities, Exchange Securities and Private Exchange Securities
            being sold, their Special Counsel or the managing underwriters (if
            any) and (iii) its independent public accountants to provide a
            comfort letter or letters in customary form, subject to receipt of
            appropriate documentation as contemplated, and only if permitted, by
            Statement of Auditing Standards No. 72.

5.    REGISTRATION EXPENSES. The Company will bear all expenses incurred in
      connection with the performance of its obligations under Sections 1, 2, 3
      and 4 and the Company will reimburse the Holders for the reasonable fees
      and disbursements of

                                       12
<PAGE>

      one firm of attorneys (in addition to any local counsel) chosen by the
      Holders of a majority in aggregate principal amount of the Securities, the
      Exchange Securities and the Private Exchange Securities to be sold
      pursuant to each Registration Statement (the "SPECIAL COUNSEL") acting for
      the Holders in connection therewith.

6.    INDEMNIFICATION. (a) In the event of a Shelf Registration Statement or in
      connection with any prospectus delivery pursuant to an Exchange Offer
      Registration Statement by an Holder or Exchanging Dealer, as applicable,
      the Company shall indemnify and hold harmless each Holder (including,
      without limitation, any such Exchanging Dealer), its affiliates, their
      respective officers, directors, employees, representatives and agents, and
      each person, if any, who controls such Holder within the meaning of the
      Securities Act or the Exchange Act (collectively referred to for purposes
      of this Section 6 and Section 7 as a Holder) from and against any loss,
      claim, damage or liability, joint or several, or any action in respect
      thereof (including, without limitation, any loss, claim, damage, liability
      or action relating to purchases and sales of Securities, Exchange
      Securities or Private Exchange Securities), to which that Holder may
      become subject, whether commenced or threatened, under the Securities Act,
      the Exchange Act, any other federal or state statutory law or regulation,
      at common law or otherwise, insofar as such loss, claim, damage, liability
      or action is based upon, (i) any untrue statement or alleged untrue
      statement of a material fact contained in any such Registration Statement
      or any prospectus forming part thereof or in any amendment or supplement
      thereto or (ii) the omission or alleged omission to state therein 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, and shall reimburse each Holder promptly upon
      demand for any legal or other expenses reasonably incurred by that Holder
      in connection with investigating or defending or preparing to defend
      against or appearing as a third party witness in connection with any such
      loss, claim, damage, liability or action as such expenses are incurred;
      PROVIDED, HOWEVER, that the Company shall not be liable in any such case
      to the extent that any such loss, claim, damage, liability or action
      arises out of, or is based upon, an untrue statement or alleged untrue
      statement in or omission or alleged omission from any of such documents in
      reliance upon and in conformity with any Holders' Information; and
      PROVIDED, FURTHER, that with respect to any such untrue statement in or
      omission from any related preliminary prospectus, the indemnity agreement
      contained in this Section 6(a) shall not inure to the benefit of any
      Holder from whom the person asserting any such loss, claim, damage,
      liability or action received Securities, Exchange Securities or Private
      Exchange Securities to the extent that such loss, claim, damage, liability
      or action of or with respect to such Holder results from the fact that
      both (A) a copy of the final prospectus was not sent or given to such
      person at or prior to the written confirmation of the sale of such
      Securities, Exchange Securities or Private Exchange Securities to such
      person and (B) the untrue statement in or omission from the related
      preliminary prospectus was corrected in the final prospectus unless, in
      either case, such failure to deliver the final prospectus was a result of
      non-compliance by the Company with Section 4(d), 4(e), 4(f) or 4(g).

            (b) In the event of a Shelf Registration Statement, each Holder
shall indemnify and hold harmless the Company, its affiliates, their respective
officers,

                                       13
<PAGE>

directors, employees, representatives and agents, and each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange
Act (collectively referred to for purposes of this Section 6(b) and Section 7 as
the Company), from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company may become
subject, whether commenced or threatened, under the Securities Act, the Exchange
Act, any other federal or state statutory law or regulation, at common law or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained in any such Registration Statement or any prospectus
forming part thereof or in any amendment or supplement thereto or (ii) the
omission or alleged omission to state therein 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, but in
each case only to the extent that the untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with any Holders' Information furnished to the Company by such
Holder, and shall reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
or preparing to defend against or appearing as a third party witness in
connection with any such loss, claim, damage, liability or action as such
expenses are incurred; PROVIDED, HOWEVER, that no such Holder shall be liable
for any indemnity claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Securities, Exchange Securities or
Private Exchange Securities pursuant to such Shelf Registration Statement.

            (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; PROVIDED,
HOWEVER, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and PROVIDED, FURTHER, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 6. If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; PROVIDED, HOWEVER,
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from

                                       14
<PAGE>

or in addition to those available to the indemnifying party, (3) a conflict or
potential conflict exists (based upon advice of counsel to the indemnified
party) between the indemnified party and the indemnifying party (in which case
the indemnifying party will not have the right to direct the defense of such
action on behalf of the indemnified party) or (4) the indemnifying party has not
in fact employed counsel reasonably satisfactory to the indemnified party to
assume the defense of such action within a reasonable time after receiving
notice of the commencement of the action, in each of which cases the reasonable
fees, disbursements and other charges of counsel will be at the expense of the
indemnifying party or parties. It is understood that the indemnifying party or
parties shall not, in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees, disbursements and
other charges of more than one separate firm of attorneys (in addition to any
local counsel) at any one time for all such indemnified party or parties. Each
indemnified party, as a condition of the indemnity agreements contained in
Sections 6(a) and 6(b), shall use all reasonable efforts to cooperate with the
indemnifying party in the defense of any such action or claim. No indemnifying
party shall be liable for any settlement of any such action effected without its
written consent (which consent shall not be unreasonably withheld), but if
settled with its written consent or if there be a final judgment for the
plaintiff in any such action, the indemnifying party agrees to indemnify and
hold harmless any indemnified party from and against any loss or liability by
reason of such settlement or judgment. No indemnifying party shall, without the
prior written consent of the indemnified party (which consent shall not be
unreasonably withheld), effect any settlement of any pending or threatened
proceeding 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 includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

7.    CONTRIBUTION. If the indemnification provided for in Section 6 is
      unavailable or insufficient to hold harmless an indemnified party under
      Section 6(a) or 6(b), then each indemnifying party shall, in lieu of
      indemnifying such indemnified party, contribute to the amount paid or
      payable by such indemnified party as a result of such loss, claim, damage
      or liability, or action in respect thereof, (i) in such proportion as
      shall be appropriate to reflect the relative benefits received by the
      Company from the offering and sale of the Securities, on the one hand, and
      a Holder with respect to the sale by such Holder of Securities, Exchange
      Securities or Private Exchange Securities, on the other, or (ii) if the
      allocation provided by clause (i) above is not permitted by applicable
      law, in such proportion as is appropriate to reflect not only the relative
      benefits referred to in clause (i) above but also the relative fault of
      the Company on the one hand and such Holder on the other with respect to
      the statements or omissions that resulted in such loss, claim, damage or
      liability, or action in respect thereof, as well as any other relevant
      equitable considerations. The relative benefits received by the Company on
      the one hand and a Holder on the other with respect to such offering and
      such sale shall be deemed to be in the same proportion as the total net
      proceeds from the offering of the Securities (before deducting expenses)
      received by or on behalf of the Company as set forth in the table on the
      cover of the Offering Memorandum, on the one hand, bear to the total
      proceeds received by such Holder with respect to its sale of Securities,
      Exchange Securities or Private Exchange Securities, on the other. The
      relative fault

                                       15
<PAGE>

      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 the Company or
      information supplied by the Company on the one hand or to any Holders'
      Information supplied by such Holder on the other, the intent of the
      parties and their relative knowledge, access to information and
      opportunity to correct or prevent such untrue statement or omission. The
      parties hereto agree that it would not be just and equitable if
      contributions pursuant to this Section 7 were to be determined by PRO RATA
      allocation or by any other method of allocation that does not take into
      account the equitable considerations referred to herein. The amount paid
      or payable by an indemnified party as a result of the loss, claim, damage
      or liability, or action in respect thereof, referred to above in this
      Section 7 shall be deemed to include, for purposes of this Section 7, any
      legal or other expenses reasonably incurred by such indemnified party in
      connection with investigating or defending or preparing to defend any such
      action or claim. Notwithstanding the provisions of this Section 7, an
      indemnifying party that is a Holder of Securities, Exchange Securities or
      Private Exchange Securities shall not be required to contribute any amount
      in excess of the amount by which the total price at which the Securities,
      Exchange Securities or Private Exchange Securities sold by such
      indemnifying party to any purchaser exceeds the amount of any damages
      which such indemnifying party has otherwise paid or become liable to pay
      by reason of any 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.

8.    RULES 144 AND 144A. The Company shall use its reasonable best efforts to
      file the reports required to be filed by it under the Securities Act and
      the Exchange Act of 1934, as amended, and the rules and regulations of the
      Commission promulgated thereunder (the "EXCHANGE ACT") in a timely manner
      and, if at any time the Company is not required to file such reports, it
      will, upon the written request of any Holder of Transfer Restricted
      Securities, make publicly available other information so long as necessary
      to permit sales of such Holder's securities pursuant to Rules 144 and
      144A. The Company covenants that it will take such further action as any
      Holder of Transfer Restricted Securities may reasonably request, all to
      the extent required from time to time to enable such Holder to sell
      Transfer Restricted Securities without registration under the Securities
      Act within the limitation of the exemptions provided by Rules 144 and 144A
      (including, without limitation, the requirements of Rule 144A(d)(4)). Upon
      the written request of any Holder of Transfer Restricted Securities, the
      Company shall deliver to such Holder a written statement as to whether it
      has complied with such requirements. Notwithstanding the foregoing,
      nothing in this Section 8 shall be deemed to require the Company to
      register any of its securities pursuant to the Exchange Act.

9.    UNDERWRITTEN REGISTRATIONS. If any of the Transfer Restricted Securities
      covered by any Shelf Registration Statement are to be sold in an
      underwritten offering, the investment banker or investment bankers and
      manager or managers that will administer the offering will be selected by
      the Holders of a majority in aggregate principal amount of such Transfer
      Restricted Securities included in such offering,

                                       16
<PAGE>

      subject to the consent of the Company (which shall not be unreasonably

hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

                                               TO REGISTRATION RIGHTS AGREEMENT

            Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Registered 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
Securities where such 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 90 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"

                                                TO REGISTRATION RIGHTS AGREEMENT

                  Each broker-dealer that receives Exchange Securities for its
own account in exchange for Securities, where such 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

                                                TO REGISTRATION RIGHTS AGREEMENT

                              PLAN OF DISTRIBUTION

            Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Registered 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 Securities where such Securities were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that, for a period of 90 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.

            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 Registered 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 at 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
Registered 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 90 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 Registered Exchange Offer (including the expenses of one counsel
for the Holders of the Securities) other than commissions or concessions of any
broker-dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

            the use of EchoMark(R), EchoEye(R)and ColorMark(R)patents and

            Use" shall include the application of the EchoMark(R), EchoEye(R)and
            ColorMark(R)patents and technology as it applies to any and all

            4.2 being hereby incorporated by reference as if more fully set
            forth herein. EchoCath covenants that it will pay all patent
            maintenance fees as they become due with respect to the EchoMark(R),
            EchoEye(R)and ColorMark(R)patents. To the extent EchoCath should
            fail to pay such patent maintenance fees as they become due,
            EchoCath will notify EP Med, and EP Med is authorized by EchoCath to
            pay such patent maintenance fees and any surcharges thereon. If
            EchoCath does not reimburse EP Med, EP Med will be entitled to
            reduce its obligation to pay such 2% royalty by the amount of such
            patent maintenance fees and any surcharges. In addition, Section 7.2

            thereof which incorporates (or could incorporate) or otherwise uses
            the

            incorporated by reference in its totality as if more fully set forth
            herein.
