        The
Company shall pay interest on this Note semiannually in arrears on June 15 and December 15, each an "interest payment date", of each year, commencing on
December 15, 2003, at the rate per annum specified in the title of this Note. Interest shall accrue from and including June 4, 2003 or the most recent interest payment date to which
interest had been paid or duly provided for to but excluding the date on which such interest is paid. Interest on this Note will be computed on the basis of a 360-day year of twelve
30-day months. 

        The
Company shall, (in immediately available funds) to the fullest extent permitted by law, pay interest on overdue principal (including premium, if any) and overdue installments of
interest from the original due date to the date paid, at the rate applicable to this Note plus 2% per annum, which interest shall be payable on demand. 

        All
references in the Indenture and this Note to interest shall be deemed to include a reference to additional interest payable pursuant to the Registration Rights Agreement dated as of
June 4, 2003 with respect to this Note. If additional interest is payable on this Note as contemplated under the Registration Rights Agreement, it shall be payable on each interest payment date
and at maturity to the record holder entitled to interest on such date. 

        The
interest so payable and punctually paid or duly provided for on any interest payment date will be paid to the Person in whose name this Note (or one or more Predecessor Securities)
is registered at the close of business on the June 1 or December 1 preceding such interest payment date (the "Record Date") except as provided in the Indenture. Payment of the principal
of (and premium, if any) and interest on this Note will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private
debts and as otherwise provided in the Indenture. 

	2.
	METHOD

        The
Holder must surrender this Note to a Paying Agent to collect payment of principal at maturity. The Company will make any payments of interest at maturity to the person to whom the
principal is paid. On presentation and surrender of the certificated Note, the Company will pay principal and interest in money of the United States that at the time of payment is legal tender for
payment of public and private debts. The Company will make any payments of interest on any interest payment date other than the date of maturity by check mailed to the address of the record date
registered holder as it appears in the security register; provided, however, that a Holder with an
aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions in
writing to the Trustee not less than 10 Business Days prior to the interest payment date. Any wire transfer instructions received by the trustee will remain in effect until revoked by the registered
holder. Notwithstanding the foregoing, so long as this Note is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds

	PAYING
AGENT, REGISTRAR AND CONVERSION AGENT 

        Initially,
U.S. Bank National Association (the "Trustee", which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar
and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to 

6

 

the
Holder. The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar. 

	4.
	INDENTURE,
LIMITATIONS 

        This
Note is one of a duly authorized issue of Securities of the Company designated as its 1% Convertible Subordinated Notes Due June 15, 2008 (the "Notes"), issued under an
Indenture dated as of June 4, 2003 (together with any supplemental indentures thereto, the "Indenture"), between the Company and the Trustee. The terms of this Note include those stated in the
Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Note is subject to all such
terms, and the Holder of this Note is referred to the Indenture and said Act for a statement of them. Capitalized terms used and not defined herein have the meanings assigned to such terms in the
Indenture. 

        The
Notes are subordinated unsecured obligations of the Company limited to $175,000,000 aggregate principal amount (or $200,000,000 if the initial purchasers exercise their option to
purchase additional Notes). The Indenture does not limit other debt of the Company, secured or unsecured, including Senior Indebtedness. 

	5.
	PURCHASE
OF NOTES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL 

        At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as
the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Notes held by such Holder on the date that is 30 Business Days after the occurrence of a Change
in Control, at a purchase price equal to 100% of the principal amount thereof together with accrued interest and Additional Interest, if any, up to, but excluding, the Change in Control Purchase Date.
The Holder shall have the right to withdraw any Change in Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time
prior to the close of business on the Business Day next preceding the Change in Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of
the Indenture. 

        The
Company may pay the purchase price in cash or certain securities, as set forth in the Indenture. 

	6.
	CONVERSION 

        A
Holder of a Note may convert the principal amount of such Note (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of Common Stock
at any time prior to the close of business on the Final Maturity Date; provided, however, that if the
Note is subject to purchase upon a Change in Control, the conversion right will terminate at the close of business on the Business Day immediately preceding the Change in Control Purchase Date for
such Note or such
earlier date as the Holder presents such Note for purchase (unless the Company shall default in making the Change in Control Purchase Price, when due, in which case the conversion right shall
terminate at the close of business on the date such default is cured and such Note is purchased). 

        The
initial Conversion Price is $4.013 per share, subject to adjustment under certain circumstances as provided in the Indenture. The number of shares of Common Stock issuable upon
conversion of a Note is determined by dividing the principal amount of the Note or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be
issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Closing Price (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to the
Conversion Date. 

        To
convert a Note, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Note
to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a 

7

 

Conversion
Agent, and (d) pay any transfer or similar tax, if required. Notes so surrendered for conversion (in whole or in part) during the period from the close of business on any regular
record date to the opening of business on the next succeeding interest payment date, if any, shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest
payable on such interest payment date on the principal amount of such Note then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such
Note, subject to the provisions of this Indenture relating to the payment of defaulted interest, if any, by the Company in each case to the extent provided in the Indenture, including
Section 4.2 thereof. If the Company defaults in the payment of interest payable on such interest payment date, if any, the Company shall promptly repay such funds to such Holder. A Holder may
convert a portion of a Note equal to $1,000 or any integral multiple thereof. 

        A
Note in respect of which a Holder had delivered a Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Note may be converted
only if the Change in Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 

	7.
	SUBORDINATION 

        The
indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all
Senior Indebtedness of the Company (including any interest accruing subsequent to the commencement of any bankruptcy or similar proceeding, whether or not a claim for post-petition
interest is allowed as a claim in any such proceeding). Any Holder by accepting this Note agrees to and shall be
bound by such subordination provisions and authorizes the Trustee to give them effect. In addition to all other rights of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall
continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any terms of any instrument relating to the
Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 

	8.
	DENOMINATIONS,
TRANSFER, EXCHANGE, CANCELLATION 

        The
Notes are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Notes in accordance with
the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed
in relation thereto by law or permitted by the Indenture. 

        All
Notes surrendered for payment, registration of transfer or exchange or conversion will, if surrendered to the Company or any of its other Agents with respect to the Notes, be
delivered to the Trustee. The Trustee will promptly cancel all Notes delivered to it. No Notes will be authenticated in exchange for any Notes cancelled as provided in the Indenture. 

	9.
	PERSONS
DEEMED OWNERS 

        The
Holder of a Note may be treated as the owner of it for all purposes. 

	10.
	UNCLAIMED
MONEY 

        If
money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request, subject to
applicable unclaimed property law. After that, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another
person. 

8

 

	11.
	AMENDMENT,
SUPPLEMENT AND WAIVER 

        Subject
to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes
then outstanding, and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Notes may be waived in a particular instance with the consent
of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the
Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 

	12.
	SUCCESSOR
ENTITY

a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms and conditions of the Indenture, the
predecessor corporation (except in certain circumstances specified in the Indenture) be released from those obligations. 

	13.
	DEFAULTS
AND REMEDIES 

        Under
the Indenture, an Event of Default includes: (i) default for 30 days in payment of interest or Additional Interest, if any, on any Notes; (ii) default in
payment of any principal (including, without limitation, any premium) on the Notes when due; (iii) failure by the Company for 60 days after notice to it to comply with any of its other
covenants contained in the Indenture or the Notes; (iv) default in the payment of certain indebtedness of the Company or a Significant Subsidiary; (v) certain events of bankruptcy,
insolvency or reorganization of the Company or any Significant Subsidiary and (vi) certain other events described in the Indenture. If an Event of Default (other than as a result of certain
events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may
declare all unpaid principal to the date of acceleration on the Notes then outstanding to be due and payable immediately, all as and to the extent provided in the Indenture. If an Event of Default
occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid principal of the Notes then outstanding shall become due and payable immediately without any
declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of
the Notes then outstanding
may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it
determines that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the absence of default. 

	14.

DEALINGS WITH THE COMPANY 

        U.S.
Bank National Association, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or
an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 

	15.
	NO
RECOURSE AGAINST OTHERS 

        A
director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Notes or the Indenture nor for any claim
based on, in respect of or by reason of such obligations or their creation. The Holder of this Note by accepting this 

9

 

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

	16.

   [FORM OF REVERSE SIDE OF SECURITY]  

ADC TELECOMMUNICATIONS, INC.

FLOATING RATE CONVERTIBLE SUBORDINATED NOTES DUE JUNE 15, 2013  

	1.
	INTEREST 

        The
Company shall pay interest on this Note semiannually in arrears at the rate specified below on June 15 and December 15, each an interest payment date, commencing on
December 15, 2003. Interest shall accrue from and including June 4, 2003 or the most recent interest date to which interest has been paid or duly provided for. Interest on this Note will
be computed on the basis of a 360-day year using the actual number of days elapsed from and including an interest payment date to but excluding the next succeeding interest payment date. 

        The
Company shall, (in immediately available funds) to the fullest extent permitted by law, pay interest on overdue principal (including premium, if any) and overdue installments of
interest from the original due date to the date paid, at the rate applicable to this Note plus 2% per annum, which interest shall be payable on demand. 

        All
references in the Indenture and this Note to interest shall be deemed to include a reference to additional interest if payable pursuant to the Registration Rights Agreement dated as
of June 4, 2003 with respect to the Notes. If additional interest is payable on this Note as contemplated under the Registration Rights Agreement, it shall be payable on each interest payment
date and at maturity to the record holder entitled to interest on such date. 

        The
interest so payable and punctually paid or duly provided for on any interest payment date will be paid to the Person in whose name this Note (or one or more Predecessor Securities)
is registered at the close of business on the June 1 or December 1 preceding such interest payment date (the "Record Date") except as provided in the Indenture. Payment of the principal
of (and premium, if any) and interest on this Note will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private
debts and as otherwise provided in the Indenture. 

        The
interest rate on this Note for the period from June 4, 2003 to December 15, 2003 will be 1.5625%. The Calculation Agent will reset the interest rate on each interest
payment date, each an "interest reset date," commencing December 15, 2003. The second London business day preceding an interest reset date will be the "LIBOR determination date" for that
interest reset date. To reset the interest rate, the Calculation Agent will determine 6-month LIBOR on the LIBOR determination date and then add 0.375% to it. The interest rate in effect
on each day that is not an interest reset date will be the interest rate determined as of the LIBOR determination date pertaining to the immediately preceding interest reset date. The interest rate in
effect on any day that is an interest reset date will be the interest rate determined as of the interest determination date pertaining to that interest reset date. 

        "6-month
LIBOR" means: 

	a)
	the
rate for six-month deposits in United States dollars commencing on the related interest payment date, that appears on the Moneyline Telerate Page 3750 as of
11:00 a.m., London time, on the LIBOR determination date; or

	b)
	if
no rate appears on the particular LIBOR determination date on the Moneyline Telerate Page 3750, the rate calculated by the calculation agent as the arithmetic mean (rounded, if
necessary, to the nearest one thousandth of a percentage point, with five one-ten thousandths of a percentage point rounded upwards) of at least two offered quotations obtained by the
calculation agent after requesting the principal London offices of each of four major reference banks in the London interbank market to provide the calculation agent with its offered 

6

 

quotation
for deposits in United States dollars for the period of six months, commencing on the related interest payment date, to prime banks in the London interbank market at approximately
11:00 a.m., London time, on that LIBOR determination date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; or 

	c)
	if
fewer than two offered quotations referred to in clause (b) are provided as requested, the rate calculated by the calculation agent as the arithmetic mean (rounded, if
necessary, to the nearest one thousandth of a percentage point, with five one-ten thousandths of a percentage point rounded upwards) of the rates quoted at approximately 11:00 a.m.,
New York time, on the particular LIBOR determination date by three major banks in The City of New York selected by the calculation agent for loans in United States dollars to leading European banks
for a period of six months and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; or

	d)
	if
the banks so selected by the calculation agent are not quoting as mentioned in clause (c), 6-month LIBOR in effect on the preceding LIBOR determination date
(1.5625% per annum in the case of the reset on December 15, 2003). 

        "Moneyline
Telerate Page 3750" means the display on Moneyline Telerate (or any successor service) on such page (or any other page as may replace such page on such service) for the
purpose of displaying the London interbank rates of major banks for United States dollars. 

        "London
banking day" means a day on which commercial banks are open for business, including dealings in United States dollars, in London. 

        The
Calculation Agent shall be U.S. Bank National Association, or such other Person as the Company shall from time to time designate. 

	1.
	METHOD
OF PAYMENT 

        The
Holder must surrender this Note to a Paying Agent to collect payment of principal at maturity. The Company will make any payments of interest at maturity to the person to whom the
principal is paid. On presentation and surrender of the certificated Note, the Company will pay principal and interest in money of the United States that at the time of payment is legal tender for
payment of public and private debts. The Company will make any payments of interest on any interest payment date other than the date of maturity by check mailed to the address of the record date
registered holder as it appears in the security register; provided, however, that a Holder with an
aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions in
writing to the Trustee not less than 10 Business Days prior to the interest payment date. Any wire transfer instructions received by the trustee will remain in effect until revoked by the registered
holder. Notwithstanding the foregoing, so long as this Note is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds
to the account of the Depositary or its nominee. 

	2.
	PAYING
AGENT, REGISTRAR AND CONVERSION AGENT 

        Initially,
U.S. Bank National Association (the "Trustee", which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar
and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Subsidiaries may, subject to certain limitations
set forth in the Indenture, act as Paying Agent or Registrar.

	3.
	INDENTURE,
LIMITATIONS 

        This
Note is one of a duly authorized issue of Securities of the Company designated as its Floating Rate Convertible Subordinated Notes Due June 15, 2013 (the "Notes"), issued
under an Indenture dated as of June 4, 2003 (together with any supplemental indentures thereto, the "Indenture"), between the Company and the Trustee. The terms of this Note include those
stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Note is subject
to all such terms, and the Holder of this Note is referred to the Indenture and said Act for a statement of them. Capitalized terms used and not defined herein have the meanings assigned to such terms
in the Indenture. 

        The
Notes are subordinated unsecured obligations of the Company limited to $175,000,000 aggregate principal amount (or $200,000,000 if the Initial Purchasers exercise their option to
purchase additional Notes). The Indenture does not limit other debt of the Company, secured or unsecured, including Senior Indebtedness. 

	4.
	PURCHASE
OF NOTES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL 

        At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as
the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Notes held by
such Holder on the date that is 30 Business Days after the occurrence of a Change in Control, at a purchase price equal to 100% of the principal amount thereof together with accrued interest and
Additional Interest, if any, up to, but excluding, the Change in Control Purchase Date. The Holder shall have the right to withdraw any Change in Control Purchase Notice (in whole or in a portion
thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date by
delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 

        The
Company may pay the purchase price in cash or certain securities, as set forth in the Indenture. 

	5.
	CONVERSION 

        A
Holder of a Note may convert the principal amount of such Note (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of Common Stock
at any time prior to the close of business on the Final Maturity Date; provided, however, that if the
Note is subject to redemption or purchase upon a Change in Control, the conversion right will terminate at the close of business on the Business Day immediately preceding the Redemption Date or Change
in Control Purchase Date for such Note or such earlier date as the Holder presents such Note for purchase (unless the Company shall default in making the Redemption Price or Change in Control Purchase
Price, when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Note is purchased). 

        The
initial Conversion Price is $4.013 per share, subject to adjustment under certain circumstances as provided in the Indenture. The number of shares of Common Stock issuable upon
conversion of a Note is determined by dividing the principal amount of the Note or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be
issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Closing Price (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to the
Conversion Date. 

        To
convert a Note, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Note
to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required.
Notes so surrendered for 

8

 

conversion
(in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next succeeding interest payment date, if any, shall also be
accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such interest payment date on the principal amount of such Note then being converted, and such
interest shall be payable to such registered Holder notwithstanding the conversion of such Note, subject to the provisions of this Indenture relating to the payment of defaulted interest, if any, by
the Company in each case to the extent provided in the Indenture, including Section 4.2 thereof. If the Company defaults in the payment of interest payable on such interest payment date, if
any, the Company shall promptly repay such funds to such Holder. A Holder may convert a portion of a Note equal to $1,000 or any integral multiple thereof. 

        A
Note in respect of which a Holder had delivered a Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Note may be converted
only if the Change in Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 

	6.
	SUBORDINATION

        The
indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all
Senior Indebtedness of the Company (including any interest accruing subsequent to the commencement of any bankruptcy or similar proceeding, whether or not a claim for post-petition
interest is allowed as a claim in any such proceeding). Any Holder by accepting this Note agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect.
In addition to all other rights of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination
provisions irrespective of any amendment, modification or waiver of any terms of any instrument relating to the Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 

	7.
	DENOMINATIONS,
TRANSFER, EXCHANGE, CANCELLATION 

        The
Notes are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Notes in accordance with
the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed
in relation thereto by law or permitted by the Indenture. 

        All
Notes surrendered for payment, registration of transfer or exchange or conversion will, if surrendered to the Company or any of its other Agents with respect to the Notes, be
delivered to the Trustee. The Trustee will promptly cancel all Notes delivered to it. No Notes will be authenticated in exchange for any Notes cancelled as provided in the Indenture. 

	8.
	PERSONS
DEEMED OWNERS 

        The
Holder of a Note may be treated as the owner of it for all purposes. 

	9.
	UNCLAIMED
MONEY 

        If
money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request, subject to
applicable unclaimed property law. After that, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another
person. 

	10.
	AMENDMENT,
SUPPLEMENT AND WAIVER 

        Subject
to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes
then 

9

 

outstanding,
and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Notes may be waived in a particular instance with the consent of
the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture
or the Notes to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 

	11.
	SUCCESSOR
ENTITY 

        When
a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms and conditions of the Indenture, the
predecessor corporation (except in certain circumstances specified in the Indenture) be released from those obligations. 

	12.
	DEFAULTS
AND REMEDIES 

        Under
the Indenture, an Event of Default includes: (i) default for 30 days in payment of interest or Additional Interest, if any, on any Notes; (ii) default in
payment of any principal (including, without limitation, any premium) on the Notes when due; (iii) failure by the Company for 60 days after notice to it to comply with any of its other
covenants contained in the Indenture or the Notes; (iv) default in the payment of certain indebtedness of the Company or a Significant Subsidiary; (v) certain events of bankruptcy,
insolvency or reorganization of the Company or any Significant Subsidiary and (vi) certain other events described in the Indenture. If an Event of Default (other than as a result of certain
events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may
declare all unpaid principal to the date of acceleration on the Notes then outstanding to be due and payable immediately, all as and to the extent provided in the Indenture. If an Event of Default
occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid principal of the Notes then outstanding shall become due and payable immediately without any
declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of
the Notes then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of
principal or interest) if it determines
that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the absence of default. 

	13.
