K. Michael Forrest 

Interim Chief Executive officer 

AVI BioPharma, Inc. 

One SW Columbia 

Suite 1105 

Portland OR 97258 

Dear Michael; 

 

As the largest individual
shareholder of AVI BioPharma, Inc. (the “Company”), I am obviously quite
interested in the direction that the Company is heading. As you know, since I
became a more than 5% shareholder in March 2005, as reflected in my Schedule
13G filings under the Securities Exchange Act of 1934, I have not had any
intention or taken any actions to change the management or control of the
Company. My position has not changed.

 

In recent months, the
Company has made several changes in management and focus, which I have supported
and continue to support.

I also understand that you are contemplating certain additional changes and
certain transactions, and you have requested that I execute this letter in
connection therewith. Accordingly, as show of support and to better enable the
Company to effect these changes and transactions without undue interference or
disruption, I agree that for 120 days following the date of any agreement you
reach with AVI BioPharma Shareholder Advocacy Trust on or prior to October 29,
2007, 1 will not change my position as a passive shareholder and will not
actively support any action of any other shareholder, including the AVI
BioPharma Shareholder Advocacy Trust, that may call for additional changes in
the Company’s management, Board structure or Board composition, or any
transaction that would, if successful, result in a change of control of the
Company. 

 

Sincerely, 

George HaywoodExhibit 4.01

NORTHERN
STATES POWER COMPANY, a corporation organized and existing under the laws of
the State of Minnesota (the “Company”), for value received, hereby promises to
pay to [                          ]
or its registered assigns, at the office of the Trustee, in the City of
Chicago, Illinois, or, at the option of the registered owner, at the agency of

Dollars in lawful money of the United States of America, on the 1st day of March, 2018, and to pay
interest hereon from the date hereof at the rate of 5.25 percent per annum, in
like money, until the Company’s obligation with respect to the payment of such

several series of varying denominations, dates and tenor, all issued
and to be issued under and equally secured (except insofar as a sinking fund,
or similar fund, established in accordance with the provisions of the Indenture
may afford additional security for the bonds of any specific series) by a Trust
Indenture dated February 1, 1937 (the “1937 Indenture”), as supplemented
by 58 supplemental trust indentures (collectively, the “Supplemental Indentures”),
a Supplemental and Restated Trust Indenture dated May 1, 1988 (the “Restated
Indenture”) and a new supplemental trust indenture for the bonds of this series
(the “Supplemental Trust Indenture”), executed by the Company to THE BANK OF
NEW YORK TRUST COMPANY, N.A. (as successor trustee to Harris Trust and Savings
Bank and BNY Midwest Trust Company), as trustee (the “Trustee”).  The 1937 Indenture, as supplemented by the
Supplemental Indentures, the Restated Indenture and the Supplemental Trust
Indenture, is referred to herein as the “Indenture.”  The Restated Indenture amends and restates
the 1937 Indenture and certain of the Supplemental Indentures and became
effective and operative on July 20, 2005.  Reference hereby is made to the Indenture for
a description of the property mortgaged and pledged, the nature and extent of
the security, the rights of the holders of the bonds as to such security and
the terms and conditions upon which the bonds may be issued under the Indenture
and are secured.  The principal hereof
may be declared or may become due on the conditions, in the manner and at the
time set forth in the Indenture upon the happening of a default as provided in
the Indenture.

 

With the
consent of the Company and to the extent permitted by and as provided in the
Indenture, the rights and obligations of the Company and of the holders of the
bonds and the terms and provisions of the Indenture and of any instruments
supplemental thereto may be modified or altered by affirmative vote of the
holders of at least 66 2/3% in principal amount of the bonds then outstanding
under the Indenture and any instruments supplemental thereto (excluding bonds
challenged and disqualified from voting by reason of the Company’s interest
therein as provided in the Indenture); provided that without the consent of all
holders of all bonds affected no such modification or alteration shall permit
the extension of the maturity of the principal of any bond or the reduction in
the rate of interest thereon or any other modification in the terms of payment
of such principal or interest.

 

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

 

The bonds of this series shall be
redeemable at the option of the Company, as a whole or in part, on any date
upon not less than 30 days’ previous notice to be given in the manner and with
the effect provided in Section 10.02 of the Restated Indenture at a
redemption price equal to the greater of (a) the principal amount of the
bonds of this series being redeemed or (b) the sum of the present values
of the remaining scheduled payments of principal and interest on the bonds of
this series that are being redeemed (exclusive of interest accrued to the date
of redemption), discounted to the redemption date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Yield plus 30 basis points, plus in each case accrued and unpaid interest to
the date of redemption.

 

“Treasury Yield” 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 

 

6

 

is published weekly by the Board of Governors
of the Federal Reserve System and which establishes yields on actively traded
U.S. Treasury securities adjusted to constant maturity under the caption “Treasury
Constant Maturities,” for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the remaining
term, yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue will be determined and the Treasury Yield will be
interpolated or extrapolated from such yields on a straight line basis,
rounding to the nearest month); or (ii) if such 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 semi-annual
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 such redemption
date.  The Treasury Yield will be
calculated on the third business day preceding the date fixed for redemption.

 

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

 

“Comparable Treasury Price” means (i) the
average of the Reference Treasury Dealer Quotations for such redemption date,
after excluding the highest and lowest of such Reference Treasury Dealer
Quotations for such redemption date, or (ii) if the Trustee obtains fewer
than four such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations.

 

“Independent Investment Banker” means
Barclays Capital Inc. or its successors or, if such firm or its successors are
unwilling or unable to select the Comparable Treasury Issue, an independent
investment banking institution of national standing appointed by the Trustee
after consultation with the Company.

 

“Reference Treasury Dealer” means (i) Barclays
Capital Inc. or J.P. Morgan Securities Inc. and any other primary U.S.
Government securities dealer in the United States (a “Primary Treasury Dealer”)
designated by, and not affiliated with, Barclays Capital Inc. or J.P. Morgan
Securities Inc. and their respective successors, provided, however, that if
Barclays Capital Inc. or J.P. Morgan Securities Inc. or any of their respective
designees ceases to be a Primary Treasury Dealer, the Company shall appoint
another Primary Treasury Dealer as a substitute, and (ii) any other
Primary Treasury Dealer selected by the Company after consultation with the
Independent Investment Banker.

 

“Reference Treasury Dealer Quotations” means,
for each Reference Treasury Dealer and any redemption date, the average, as
determined by the Independent Investment Banker, 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 Independent Investment Banker by
such Reference Treasury Dealer at 5:00 p.m., Eastern time, on the third
business day preceding such redemption date.

law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released, as more fully provided in the
Indenture.

the performance of and compliance with the covenants and conditions contained

appertaining to the aforesaid property or any part thereof with the reversion
and reversions, remainder and remainders, tolls, rents and revenues, issues,

FORM AND
EXECUTION OF SERIES DUE MARCH 1, 2018

 

SECTION 2.01.  There is hereby created, for issuance under
the Indenture, a series of bonds designated Series due March 1, 2018, each of which shall bear
the descriptive title “First Mortgage Bonds, Series due March 1,
2018,” (such bonds, the “Series 2018 Bonds”) and the form thereof shall
contain suitable provisions with respect to the matters hereafter specified in
this Section.  The Series 2018 Bonds may forthwith be executed
by the Company substantially in the form set forth in the recitals, including
the relevant provisions as indicated therein, and delivered to the Trustee for
authentication and delivery by the Trustee in accordance with the provisions of
the Indenture and this Supplemental Trust Indenture.  The aggregate principal amount of the Series 2018 Bonds outstanding at any time
shall not exceed $500,000,000.  The Series 2018 Bonds shall mature on March 1,
2018, and shall be issued as registered bonds without coupons in denominations
of $1,000.  The Series 2018 Bonds
shall bear interest at a rate of 5.25% per annum on the principal amount
thereof payable semi-annually on March 1 and September 1 of each year, commencing September 1,
2008, and the principal shall be payable at the office of the Trustee in the
City of Chicago, Illinois, or at the option of the registered owner at the
agency of the Company in the Borough of Manhattan, City and State of New York,
in lawful money of the United States of America, and the interest shall be
payable in like money at the option of the person entitled to such interest
either at said office of the Trustee in the City of Chicago, Illinois, or at
the agency of the Company in the Borough of Manhattan, City and State of New
York.  Interest on the Series 2018 Bonds shall be calculated on the
basis of a 360-day year consisting of twelve 30-day months.  If any interest payment date or date on which
the principal of this bond is required to be paid is not a business day, then
payment of principal, premium or interest need not be made on such date but may
be made on the next succeeding business day with the same force and effect as
if made on such interest payment date or date on which the principal of this
bond is required to be paid and, in the case of timely payment thereof, no
interest shall accrue for the period from and after such interest payment date
or the date on 

 

11

 

which the principal of this
bond is required to be paid.  The Series 2018 Bonds shall be dated as of
the date of authentication thereof by the Trustee.  The term “business day” shall mean any day
other than a Saturday or Sunday or a day on which the offices of the Trustee in
the City of Chicago, Illinois, are closed pursuant to authorization of law.

 

As long as there is no existing default in the
payment of interest on the Series 2018 Bonds, the person in whose name any Series 2018
Bond is registered at the close of business on any Record Date with respect to
any interest payment date shall be entitled to receive the interest payable on
such interest payment date notwithstanding any transfer or exchange of any such
Series 2018 Bond subsequent to the Record Date and on or prior to such
interest payment date, except as and to the extent the Company shall default in
the payment of the interest due on such interest payment date, in which case
such defaulted interest shall be paid to the person in whose name such Series 2018
Bond is registered on the Special Record Date for the payment of such defaulted
interest to be fixed by the Trustee, notice thereof shall be given to the
registered holder of any Series 2018 Bond not less than 10 days prior to
such Special Record Date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the Series 2018
Bond may be listed, and upon such notice as may be required by such exchange.

 

The
term “Record Date” as used in this Section 2.01 with respect to any
interest payment date (March 1 or September 1) shall mean the February 15
prior to such March 1 or the August 15 prior to such September 1
(whether or not a business day).

 

As
used in this Section 2.01, the term “default in the payment of interest”
means failure to pay interest on the applicable interest payment date
disregarding any period of grace permitted by the Indenture.

 

The
“Special Record Date” as used in this Section 2.01 shall be fixed in the
following manner.  The Company shall
notify the Trustee in writing of the amount of defaulted interest proposed to
be paid on each Series 2018 Bond  and the date
of the proposed payment, and at the same time the Company shall deposit with
the Trustee 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 Trustee 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
persons entitled to such defaulted interest as provided in this Section 2.01.  Thereupon the Trustee shall fix a Special
Record Date for the payment of such defaulted interest which shall be not more
than 15 nor less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the
proposed payment.  The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
defaulted interest and the Special Record Date therefor to be mailed, first
class postage prepaid, to each holder of the Series 2018 Bonds, at his,
her or its address as it appears in the bond register, not less than 10 days
prior to such Special Record Date. 
Notice of the proposed payment of such defaulted interest and the
Special Record Date therefor having been mailed as aforesaid, such defaulted
interest shall be paid to the persons in whose names the Series 2018 Bonds
are registered on such Special Record Date and shall not be payable pursuant to
the paragraph immediately following in this Section 2.01.

 

12

 

The
Company may make payment of any defaulted interest in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the Series 2018
Bonds may be listed, and upon such notice as may be required by such exchange,
if, after notice is given by the Company to the Trustee of the proposed payment
pursuant to this Section 2.01, such payment shall be deemed practicable by
the Trustee.

 

SECTION 2.02.  The Series 2018 Bonds shall be redeemable at the
option of the Company, as a whole or in part, on any date upon not less than 30
days’ previous notice to be given in the manner and with the effect provided in
Section 10.02 of the Restated Indenture at a redemption price equal to the
greater of (a) the principal amount of the Series 2018 Bonds being redeemed or (b) the
sum of the present values of the remaining scheduled payments of principal and
interest on the Series 2018
Bonds that are being redeemed (exclusive of interest accrued to the date of
redemption), discounted to the redemption date on a semi-annual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus
30 basis points, plus in each case accrued and unpaid interest to the date of
redemption.

 

“Treasury Yield” 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 U.S. Treasury
securities adjusted to constant maturity under the caption “Treasury Constant
Maturities,” for the maturity corresponding to the Comparable Treasury Issue
(if no maturity is within three months before or after the remaining term,
yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue will be determined and the Treasury Yield will be
interpolated or extrapolated from such yields on a straight line basis,
rounding to the nearest month); or (ii) if such 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 semi-annual
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 such redemption
date.  The Treasury Yield will be
calculated on the third business day preceding the date fixed for redemption.

 

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

 

“Comparable Treasury Price” means (i) the
average of the Reference Treasury Dealer Quotations for such redemption date,
after excluding the highest and lowest of such Reference Treasury Dealer
Quotations for such redemption date, or (ii) if the Trustee obtains fewer
than four such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations.

 

“Independent Investment Banker” means Barclays
Capital Inc. or its successors or, if such firm or its successors are unwilling
or unable to select the Comparable Treasury Issue, an 

 

13

 

independent investment banking institution of
national standing appointed by the Trustee after consultation with the Company.

 

“Reference Treasury Dealer” means (i) Barclays
Capital Inc. or J.P. Morgan Securities Inc. and any other primary U.S. Government securities dealer in the
United States (a “Primary Treasury Dealer”) designated by, and not affiliated
with, Barclays Capital Inc. or J.P. Morgan Securities Inc. and their respective
successors, provided, however, that if Barclays Capital Inc. or J.P. Morgan
Securities Inc. or any of their
respective designees ceases to be a Primary Treasury Dealer, the Company shall
appoint another Primary Treasury Dealer as a substitute; and (ii) any
other Primary Treasury Dealer selected by the Company after consultation with
the Independent Investment Banker.

 

“Reference Treasury Dealer Quotations” means, for
each Reference Treasury Dealer and any redemption date, the average, as
determined by the Independent Investment Banker, 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 Independent Investment Banker by
such Reference Treasury Dealer at 5:00 p.m., Eastern time, on the third
business day preceding such redemption date.

 

The Series 2018 Bonds are not subject to a
sinking fund.

 

The redemption prices of the Series 2018 Bonds need not be specified in
any temporary bond of said series if an appropriate reference be made in said
temporary bond to the provision of this Section.

 

SECTION 2.03.  The registered owner of any Series 2018 Bond or Bonds, at his, her or
its option, may surrender the same with other bonds of such series at the
office of the Trustee in the City of Chicago, Illinois, or at the agency of the
Company in the Borough of Manhattan, City and State of New York, or elsewhere
if authorized by the Company, for cancellation, in exchange for other bonds of
such series of higher or lower authorized denominations, but of the same
aggregate principal amount, bearing interest from its date, and upon receipt of
any payment required under the provisions of Section 2.04 hereof.  Thereupon the Company shall execute and
deliver to the Trustee and the Trustee shall authenticate and deliver such
other registered bonds to such registered owner at its office or at any other
place specified as aforesaid.

 

Notwithstanding any other provisions of the
Indenture to the contrary, the Company shall not be required to issue, transfer
or exchange any Series 2018
Bond during a period of ten (10) days next preceding any selection of Series 2018
Bonds to be redeemed.  The Company shall
not be required to transfer or exchange any Series 2018 Bond called or
being called for redemption in its entirety or to transfer or exchange the
called portion of a Series 2018 Bond which has been called for partial
redemption.

 

SECTION 2.04.  No charge shall be made by the Company for
any exchange or transfer of Series 2018 Bonds  other than for taxes or other governmental charges, if
any, that may be imposed in relation thereto.

 

SECTION 2.05.  The Series 2018 Bonds shall be executed on behalf
of the Company by its President or one of its Vice Presidents, and its
corporate seal shall be thereunto affixed, or 

 

14

 

printed, lithographed or
engraved thereon, in facsimile, and attested by the signature of its Secretary
or one of its Assistant Secretaries.  Any
such signatures may be manual or facsimile signatures and may be imprinted or
otherwise reproduced.  In case any of the
officers who shall have signed any bonds or attested the seal thereon shall
cease to be such officers of the Company before the bonds so signed and sealed
actually shall have been authenticated by the Trustee or delivered by the
Company, such bonds nevertheless may be issued, authenticated and delivered
with the same force and effect as though the person or persons who signed such
bonds and attested the seal thereon had not ceased to be such officer or
officers of the Company.  Any bond
issuable hereunder may be signed or attested on behalf of the Company by such
person as at the actual date of the execution of such bond shall be the proper
officer of the Company, although at the date of such bond such person shall not
have been an officer of the Company.

 

SECTION 2.06.  (a) Except as provided in subsections (c) and
(g) below of this Section 2.06, the registered holder of all of the Series 2018 Bonds shall be The Depository
Trust Company (“DTC”) and such Series 2018 Bonds shall be registered in the
name of Cede & Co., as nominee for DTC.  Payment of principal of, premium, if any, and
interest on any Series 2018
Bonds registered in the name of Cede & Co. shall be made by
transfer of New York Federal or equivalent immediately available funds with
respect to the Series 2018
Bonds to the account of Cede & Co. on each such payment date for
the Series 2018 Bonds at the address
indicated for Cede & Co. in the bond register kept by the Trustee.

 

(b)           The Series 2018 Bonds shall be initially issued in the form of one
or more separate single authenticated fully registered certificates in the
aggregate principal amount of all Series 2018 Bonds.  Upon initial issuance, the ownership of such Series 2018 Bonds shall be registered in the
bond register kept by the Trustee in the name of Cede & Co., as
nominee of DTC.  The Trustee and the
Company may treat DTC (or its nominee) as the sole and exclusive registered
holder of the Series 2018
Bonds registered in its name for the purposes of payment of the principal
of, premium, if any, and interest on the Series 2018 Bonds and of giving any notice
permitted or required to be given to holders under the Indenture, except as
provided in subsection (g) below of this Section 2.06; and neither
the Trustee nor the Company shall be affected by any notice to the
contrary.  Neither the Trustee nor the
Company shall have any responsibility or obligation to any of DTC’s
participants (each a “Participant”), any person claiming a beneficial ownership
in the Series 2018 Bonds under or
through DTC or any Participant (each a “Beneficial Owner”) or any other person
which is not shown on the bond register maintained by the Trustee as being a
registered holder, with respect to (1) the accuracy of any records
maintained by DTC or any Participant; (2) the payment by DTC or any
Participant of any amount in respect of the principal of, premium, if any, or
interest on the Series 2018
Bonds; (3) the delivery by DTC or any Participant of any notice to any
Beneficial Owner which is permitted or required to be given to registered
holders under the Indenture of the Series 2018 Bonds; (4) the selection of
the Beneficial Owners to receive payment in the event of any partial redemption
of the Series 2018 Bonds; or (5) any
consent given or other action taken by DTC as bondholder.  The Trustee shall pay all principal of,
premium, if any, and interest on the Series 2018 Bonds registered in the name of
Cede & Co. only to or “upon the order of” (as that term is used in the
Uniform Commercial Code as adopted in Minnesota and New York) DTC, and all such
payments shall be valid and effective to fully satisfy and discharge the
Company’s obligations with respect to the principal of, premium, if any, and
interest on such Series 2018
Bonds to the extent of the sum or sums so paid.  Except as otherwise provided in subsections (c) and
(g) below of this Section 

 

15

 

2.06, no person other than
DTC shall receive authenticated bond certificates evidencing the obligation of
the Company to make payments of principal of and interest on the Series 2018 Bonds.  Upon delivery by DTC to the Trustee of
written notice to the effect that DTC has determined to substitute a new
nominee in place of Cede & Co., and subject to the provisions of the
Indenture with respect to transfers of bonds, the word “Cede & Co.” in
this Supplemental Trust Indenture shall refer to such new nominee of DTC.

 

(c)           If the Company in its discretion determines that it is in
the best interest of the Beneficial Owners that they be able to obtain bond
certificates for the Series 2018
Bonds or there shall have occurred and be continuing a Completed Default
with respect to the Series 2018
Bonds, the Company shall notify DTC and the Trustee, whereupon DTC will
notify the Participants of the availability through DTC of bond
certificates.  In such event, the Trustee
shall issue, transfer and exchange bond certificates as requested by DTC in
appropriate amounts pursuant to Article II of the Restated Indenture and Section 2.03
of this Supplemental Trust Indenture. 
The Company shall pay all costs in connection with the production of
bond certificates if the Company makes such a determination under this Section 2.06(c).  DTC may determine to discontinue providing
its services with respect to the Series 2018 Bonds at any time by giving
written notice to the Company and the Trustee and discharging its
responsibilities with respect thereto under applicable law.  Under such circumstances (if there is no
successor book-entry depository), the Company and the Trustee shall be
obligated (at the sole cost and expense of the Company) to deliver bond
certificates as described in this Supplemental Trust Indenture.  If bond certificates are issued, the
provisions of the Indenture shall apply to, among other things, the transfer
and exchange of such certificates and the method of payment of principal of,
premium, if any, and interest on such certificates.  Whenever DTC requests the Company and the
Trustee to do so, the Company will direct the Trustee (at the sole cost and
expense of the Company) to cooperate with DTC in taking appropriate action
after reasonable notice (1) to make available one or more separate
certificates evidencing the Series 2018 Bonds to any Participant or (2) to arrange
for another book-entry depository to maintain custody of certificates
evidencing the Series 2018
Bonds registered in the name of such depository or its nominee.  Any successor book-entry depository must be a
clearing agency registered with the Securities and Exchange Commission pursuant
to Section 17A of the Securities Exchange Act of 1934, as amended, and
must enter into an agreement with the Company and the Trustee agreeing to act
as the depository and clearing agency for the Series 2018 Bonds (except as provided in
subsection (g) below of this Section 2.06 ).  After such agreement has become effective,
DTC shall present the Series 2018
Bonds for registration of transfer in accordance with Section 2.12 of
the Restated Indenture, and the Trustee shall register them in the name of the
successor book-entry depository or its nominee and all references thereafter to
DTC shall be to such successor book-entry depository.  If a successor book-entry depository has not
accepted such position before the effective date of DTC’s termination of its
services, the book-entry system shall automatically terminate and may not be
reinstated without the consent of all registered holders of the Series 2018 Bonds.

 

(d)           Notwithstanding any other provision of this Supplemental
Trust Indenture to the contrary, so long as any Series 2018 Bonds are registered in the name
of Cede & Co., as nominee of DTC, all payments with respect to the
principal of, premium, if any, and interest on such Series 2018 Bonds and all notices with
respect to such Series 2018
Bonds shall be made and given, respectively, to DTC as provided in the
blanket representation letter among DTC, the 

 

16

 

Company and the
Trustee.  The Trustee is hereby authorized
and directed to comply with all terms of the representation letter.

 

(e)           In connection with any notice or other communication to be
provided pursuant to the Indenture for the Series 2018 Bonds by the Company or the
Trustee with respect to any consent or other action to be taken by the
registered holders of the Series 2018 Bonds, the Company or the Trustee, as the case may
be, shall seek to establish a record date to the extent permitted by the
Indenture for such consent or other action and give DTC notice of such record
date not less than fifteen (15) calendar days in advance of such record date to
the extent possible. Such notice to DTC shall be given only when DTC is the
sole registered holder.

 

(f)            NEITHER THE
COMPANY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATIONS TO THE
PARTICIPANTS OR THE BENEFICIAL OWNERS WITH RESPECT TO (1) THE ACCURACY OF
ANY RECORDS MAINTAINED BY DTC OR ANY PARTICIPANT; (2) THE PAYMENT BY DTC
OR ANY PARTICIPANT OF ANY AMOUNT DUE TO ANY BENEFICIAL OWNER IN RESPECT OF THE
PRINCIPAL OF, PREMIUM, IF ANY, OR INTEREST ON THE SERIES 2018 BONDS; (3) THE DELIVERY BY
DTC OR ANY PARTICIPANT OF ANY NOTICE TO ANY BENEFICIAL OWNER WHICH IS REQUIRED
OR PERMITTED UNDER THE TERMS OF THE INDENTURE TO BE GIVEN TO REGISTERED
HOLDERS; (4) THE SELECTION OF THE BENEFICIAL OWNERS TO RECEIVE PAYMENT IN
THE EVENT OF ANY PARTIAL REDEMPTION OF THE SERIES 2018 BONDS; OR (5) ANY CONSENT
GIVEN OR OTHER ACTION TAKEN BY DTC AS A REGISTERED HOLDER.

 

SO LONG AS CEDE & CO. IS THE REGISTERED
HOLDER OF THE SERIES
2018 BONDS AS NOMINEE OF DTC, REFERENCES HEREIN TO REGISTERED HOLDERS OF THE SERIES 2018 BONDS SHALL MEAN CEDE &
CO. AND SHALL NOT MEAN THE BENEFICIAL OWNERS OF THE SERIES 2018 BONDS NOR THE PARTICIPANTS.

 

(g)           The Company, in its sole discretion, may terminate the
services of DTC with respect to the Series 2018 Bonds if the Company determines
that: (i) DTC (x) is unable to discharge its responsibilities with
respect to the Series 2018
Bonds or (y) at any time ceases to be a clearing agency registered under
the Securities Exchange Act of 1934, as amended; or (ii) there shall have
occurred and be continuing a Completed Default with respect to the Series 2018 Bonds.  The Company, in its sole discretion, may
terminate the services of DTC with respect to the Series 2018 Bonds if the Company determines
that a continuation of the requirement that all of the outstanding Series 2018 Bonds be registered with
the registration books kept by the Trustee in the name of Cede & Co.,
as nominee of DTC, is not in the best interest of the Beneficial Owners of the Series 2018 Bonds.  After such event and if no substitute
book-entry depository is appointed by the Company, Series 2018 Bond certificates will be
delivered as described in the Indenture.

 

(h)           Upon the termination of the services of DTC with respect
to the Series 2018 Bonds
pursuant to subsections (c) or (g) of this Section 2.06
after which no substitute book-entry depository is appointed, the Series 2018 Bonds shall be registered in
whatever name or names holders transferring or exchanging the Series 2018 Bonds shall designate in
accordance with the provisions of the Indenture.

ARTICLE III

APPOINTMENT OF
AUTHENTICATING AGENT

 

SECTION 3.01.  The Trustee shall, if requested in writing so to
do by the Company, promptly appoint an agent or agents of the Trustee who shall
have authority to authenticate registered Series 2018 Bonds in the name
and on behalf of the Trustee.  Such
appointment by the Trustee shall be evidenced by a certificate of a
vice-president of the Trustee delivered to the Company prior to the
effectiveness of such appointment.

 

SECTION 3.02.  (a) Any such authenticating agent shall be
acceptable to the Company and at all times shall be a corporation, trust
company or banking association organized and doing business under the laws of
the United States or of any State, is authorized under such laws to act as
authenticating agent, has a combined capital and surplus of at least
$10,000,000 and is subject to supervision or examination by Federal or State
authority and to act as authenticating agent. 
If such corporation, trust company or banking association publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 3.02 the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.

 

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

 

(c)           Any
authenticating agent at any time may resign by giving written notice of
resignation to the Trustee and to the Company. 
The Trustee may at any time, and upon written request of the Company to
the Trustee shall, terminate the agency of any authenticating agent by giving
written notice of termination to such authenticating agent and to the
Company.  Upon receiving such a notice of
resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible in accordance with the provisions
of this Section 3.02, the Trustee, unless otherwise requested in writing
by the Company, promptly shall appoint a successor authenticating agent, which
shall be acceptable to the Company.  Any
successor authenticating agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally named.  No successor authenticating agent shall be
appointed unless eligible under the provisions of this Section 3.02.

 

(d)           The
Trustee agrees to pay to any authenticating agent, appointed in accordance with
the provisions of this Section 3.02, reasonable compensation for its
services, and the Trustee shall be entitled to be reimbursed for such payments.

 

18

 

SECTION 3.03.  If an appointment is made pursuant to this Article III,
the registered Series 2018 Bonds shall have endorsed thereon, in addition
to the Trustee’s Certificate, an alternate Trustee’s Certificate in the
following form:

MISCELLANEOUS

 

SECTION 5.01.  The recitals of fact herein, except the
recital that the Trustee has duly determined to execute this Supplemental Trust
Indenture and be bound, insofar as it may lawfully so do, by the provisions
hereof and in the bonds shall be taken as statements of the Company and shall
not be construed as made by the Trustee. 
The Trustee makes no representations as to the value of any of the
property subject to the lien of the Indenture, or any part thereof, or as to
the title of the Company thereto, or as to the security afforded thereby and
hereby, or as to the validity of this Supplemental Trust Indenture or of the
bonds issued under the Indenture by virtue hereof (except the Trustee’s
certificate) and the Trustee shall incur no responsibility in respect of such
matters.

 

SECTION 5.02.  This Supplemental Trust Indenture shall be
construed in connection with and as a part of the Indenture.

 

SECTION 5.03.  (a) If any provision of the Indenture or
this Supplemental Trust Indenture limits, qualifies or conflicts with another
provision of the Indenture required to be included in indentures qualified
under the Trust Indenture Act of 1939, as amended (as enacted prior to the date
of this Supplemental Trust Indenture) by any of the provisions of Sections 310
to 317, inclusive, of the said Act, such required provision shall control.

 

(b)           In case any one or more of the
provisions contained in this Supplemental Trust Indenture or in the bonds
issued hereunder shall be invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
