Upon any partial redemption of this Bond of the Series 2014, at the option of
the registered holder hereof this Bond of the Series 2014 may, but need not, be
either (i) surrendered to the Trustee in exchange for one or more new Bonds of
the Series 2014, of authorized denominations, registered in the name of such
holder, in an aggregate principal amount equal to the principal amount remaining
unpaid upon this Bond of the Series 2014, or (ii) submitted to the Trustee for
notation hereon of the payment of the portion of the principal hereof paid upon
such partial redemption.

--------------------------------------------------------------------------------

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 may be changed and
modified with the consent of the Company and upon the written consent of the
holders of at least sixty‑six and two‑thirds per centum (66‑2/3%) of the Bonds
then outstanding and entitled to consent and, in case one or more but less than
all of the series of Bonds issued under the Indenture are so affected, of at
least sixty‑six and two‑thirds per centum (66‑2/3%) in principal amount of the
Bonds then outstanding and entitled to consent of each series affected thereby,
provided that no such change shall be made which would (i) reduce the principal
of, or premium, if any, on, or the rate of interest payable on, the Bonds, or
(ii) postpone the maturity date fixed in the Indenture or in the Bonds for
payment of the principal of, or any installment of interest on, the Bonds, or
(iii) reduce the percentage of the principal amount of Bonds the consent of the
holders of which is required for the authorization of any such change or
addition, or (iv) modify, without the written consent of the Trustee, the
rights, duties or immunities of the Trustee, and further provided that, without
the consent of the holder hereof, no such change shall be made which would
(i) permit the creation of any lien (not otherwise permitted by the Indenture)
ranking prior to the lien of the Indenture on all or substantially all of the
Mortgaged Property, or (ii) deprive the holder hereof of the lien of the
Indenture upon the Mortgaged Property.
In case an Event of Default as defined in the Indenture shall occur and be
continuing, the principal of all the Bonds outstanding may be declared and may
become due and payable in the manner and with the effect provided in the
Indenture. In the event the payment of the Bonds of the Series 2014 is
accelerated pursuant to the Indenture, the aggregate principal amount hereof and
interest hereon shall be payable together with the Make-Whole Amount, if any.
This Bond of the Series 2014 is a registered Bond and, subject to the
restriction on transfer set forth in the legend on this Bond of the Series 2014,
is transferable by the registered holder hereof in person or by the duly
authorized attorney of such holder on the registration books to be kept for the
purpose at the principal office of the Trustee, Registrar for the Bonds, in the
City of Minneapolis, Minnesota, upon surrender of this Bond of the Series 2014
accompanied by a written instrument of transfer in form approved by the Company,
duly executed by the registered bolder in person or by such attorney, and upon
cancellation hereof one or more new registered Bonds without coupons, of
authorized denominations, for the same aggregate principal amount, will be
issued to the transferee in exchange herefor, as provided in the Indenture.
The Company and the Trustee may deem and treat the person in whose name this
Bond of the Series 2014 is registered on such books as the absolute owner hereof
(whether or not this Bond of the Series 2014 shall be overdue) for the purpose
of receiving payment hereof, and on the account hereof and for all other
purposes, and neither the Company nor the Trustee shall be affected by any
notice to the contrary.

-12-

--------------------------------------------------------------------------------

As a condition precedent to any transfer referred to above, the Company may
require payment by the holder of a sum sufficient to reimburse it for any stamp
tax or any other governmental charge with respect to any transfer involved
therein.
No recourse shall be had for the payment of the principal of or interest on this
Bond of the Series 2014, or in respect of this Bond of the Series 2014 or the
Indenture, against any incorporator, stockholder, officer or director, as such,
past, present or future, of the Company or of any predecessor or successor
corporation, either directly or through the Company, by virtue of any
constitution, statute or rule of law or by enforcement of any assessment or
penalty or otherwise, any and all such liability of incorporators, stockholders,
officers and directors being released by the holder hereof by the acceptance of
this Bond and being likewise waived and released by the terms of the Indenture.

requirements of the Indenture in respect thereof, including, but not limited to,
the Property Additions Certificate of the Company delivered in connection with
the issuance of the Bonds of the Series 2014, the Trustee shall authenticate
said Bonds of the Series 2014 and deliver them to or upon the Written Order or
Orders of the Company, without awaiting the recordation or filing for

Section 1.4.    At the option of the registered owner, any Bonds of the
Series 2014, upon surrender thereof for cancellation at the office or agency of

with the applicable provisions of the Indenture and receipt of consideration
therefor by the Company, there shall be an initial issue of Bonds of the
Series 2014 for the aggregate principal amount of $75,000,000.
Section 1.5.    Notwithstanding anything to the contrary in this Second
Supplemental Indenture, payments on the Bonds of the Series 2014 shall be made
in accordance with Section 9 of the Bond Purchase Agreement (as defined in
Section 3.3 of this Second Supplemental Indenture) and the Trustee shall be
entitled to conclusively assume that any holder of such Bonds is entitled to the

shall indemnify and save the Trustee harmless from any liabilities and costs
incurred by the Trustee arising out of the making of the final or any partial
payment when due of the principal owing on any of the Bonds of the Series 2014
without surrender of such Bond to the Trustee.
ARTICLE II
REDEMPTION OF THE BONDS OF THE SERIES 2014    
Section 2.1.    The entire unpaid principal balance of the Bonds of the
Series 2014 shall be due and payable on the stated maturity date thereof.
Section 2.2.    Pursuant to the Indenture, the Bonds of the Series 2014 are
subject to redemption, in whole or in part, out of certain monies required to be
deposited with the Trustee, but in such cases the redemption shall be effected
at the principal amount of the Bonds of the Series 2014 to be redeemed and
accrued interest to the date fixed for redemption, without premium, if redeemed
pursuant to Section 10.07 of the Indenture.
Section 2.3.    (a) The Company may, at its option, upon notice as provided
below, prepay at any time all, or from time to time any part of, the Bonds of
the Series 2014 at 100% of the principal amount so prepaid, and the Make‑Whole
Amount determined for the Settlement Date specified by the Company in such
notice with respect to such principal amount. The Company, or the Trustee (at
the Company’s written request in the name and at the expense of the Company),
will give each registered owner of Bonds of the Series 2014 written notice (by
first class mail or such other method as may be agreed upon by the Company and
such registered owner) of each optional prepayment under this Section 2.3(a) not
less than 10 days and not more than 60 days prior to the date fixed for such
prepayment, to each such registered owner at its last address appearing on the
Bond Register. Each such notice shall specify the Settlement Date (which shall
be a Business Day), the aggregate principal amount of the Bonds of the
Series 2014 to be prepaid on such date, the principal amount of each Bond held
by such registered owner to be prepaid (determined in accordance with

-16-

--------------------------------------------------------------------------------

subsection (b) of this Section 2.3), and the interest to be paid on the
Settlement Date with respect to such principal amount being prepaid, and shall
be accompanied by a certificate signed by a Senior Financial Officer as to the
estimated Make‑Whole Amount due in connection with such prepayment (calculated
as if the date of such notice were the date of the prepayment), setting forth
the details of such computation. Two Business Days prior to such Settlement
Date, the Company, or the Trustee (at the Company’s written request in the name
and at the expense of the Company), shall send to each registered owner of Bonds
of the Series 2014 (by first class mail or by such other method as may be agreed
upon by the Company and such registered owner) a certificate signed by a Senior
Financial Officer specifying the calculation of such Make‑Whole Amount as of the
specified Settlement Date. As promptly as practicable after the giving of the
notice and the sending of the certificates provided in this subsection, the
Company shall provide a copy of each to the Trustee (unless the Company has
elected in writing to have the Trustee deliver such notices and certificates, in
which case the Company shall not be required to provide further copies). The
Trustee shall be under no duty to inquire into, may conclusively presume the
correctness of, and shall be fully protected in relying upon the information set
forth in any such notice or certificate. The Bonds of the Series 2014 are not
otherwise subject to voluntary or optional prepayment.
(b)    In the case of each partial prepayment of the Bonds of the Series 2014,
the principal amount of the Bonds of the Series 2014 to be prepaid shall be
allocated by the Company among all of the Bonds of the Series 2014 at the time
outstanding in proportion, as nearly as practicable, to the respective unpaid
principal amounts thereof not theretofore called for prepayment; provided that
the remaining principal amount of each Bond shall be an authorized denomination.
(c)    In the case of each notice of prepayment of Bonds of the Series 2014
pursuant to this Section 2.3, if cash sufficient to pay the principal amount to
be prepaid on the Settlement Date (which shall be a Business Day), together with
interest on such principal amount accrued to such date and the applicable
Make‑Whole Amount, if any, is not paid as agreed upon by the Company and each
registered owner of the affected Bonds, or, to the extent that there is no such
agreement entered into with one or more such owners, deposited with the Trustee
on or before the Settlement Date, then such notice of prepayment shall be of no
effect. If such cash is so paid or deposited, such principal amount of the Bonds
of the Series 2014 shall be deemed paid for all purposes and interest on such
principal amount shall cease to accrue. In case the Company pays any registered
owner pursuant to an agreement with that registered owner, the Company shall
notify the Trustee as promptly as practicable of such agreement and payment, and
shall furnish the Trustee with a copy of such agreement; in case the Company
deposits any cash with the Trustee, the Company shall provide therewith a list
of the registered owners and the amount of such cash each registered owner is to
receive. The Trustee shall be under no duty to inquire into, may conclusively
presume the correctness of, and shall be fully protected in relying upon the
information set forth in any such notice, list or agreement, and shall not be
chargeable with knowledge of any of the contents of any

-17-

--------------------------------------------------------------------------------

such agreement. Any Bond prepaid in full shall be surrendered to the Company or
the Trustee for cancellation (and shall not be reissued) in accordance with
Section 9 of the Bond Purchase Agreement referred to in Section 3.3 of this
Second Supplemental Indenture.
(d)    “Make‑Whole Amount” means, with respect to any Bond of the Series 2014,
an amount equal to the excess, if any, of the Discounted Value of the Remaining
Scheduled Payments with respect to the Called Principal of such Bond of the
Series 2014 over the amount of such Called Principal, provided that the
Make‑Whole Amount may in no event be less than zero. For the purposes of
determining the Make‑Whole Amount, the following terms have the following
meanings:
“Business Day” means any day other than a Saturday, a Sunday or a day on which
commercial banks in New York City are required or authorized to be closed.
“Called Principal” means, with respect to any Bond of the Series 2014, the
principal of such bond that is to be prepaid pursuant to subsection (a) of this
Section 2.3 or has become or is declared to be immediately due and payable
pursuant to Article XI of the Indenture, as the context requires.
“Discounted Value” means, with respect to the Called Principal of any Bond of
the Series 2014, the amount obtained by discounting all Remaining Scheduled
Payments with respect to such Called Principal from their respective scheduled
due dates to the Settlement Date with respect to such Called Principal, in
accordance with accepted financial practice and at a discount factor (applied on
the same periodic basis as that on which interest on the Bonds of the
Series 2014 is payable) equal to the Reinvestment Yield with respect to such
Called Principal.
“Reinvestment Yield” means, with respect to the Called Principal of any Bond of
the Series 2014, 0.50% over the yield to maturity implied by (i) the yields
reported as of 10:00 a.m. (New York City time) on the second Business Day
preceding the Settlement Date with respect to such Called Principal, on the
display designated as “Page PX1” (or such other display as may replace Page PX1)
on Bloomberg Financial Markets for the most recently issued actively traded U.S.
Treasury securities having a maturity equal to the Remaining Average Life of
such Called Principal as of such Settlement Date, or (ii) if such yields are not
reported as of such time or the yields reported as of such time are not
ascertainable (including by way of interpolation), the Treasury Constant
Maturity Series Yields reported, for the latest day for which such yields have
been so reported as of the second Business Day preceding the Settlement Date
with respect to such Called Principal, in Federal Reserve Statistical Release
H.15 (519) (or any comparable successor publication)

-18-

--------------------------------------------------------------------------------

for actively traded U.S. Treasury securities having a constant maturity equal to
the Remaining Average Life of such Called Principal as of such Settlement Date.
Such implied yield will be determined, if necessary, by (a) converting U.S.
Treasury bill quotations to bond equivalent yields in accordance with accepted
financial practice and (b) interpolating linearly between (1) the actively
traded U.S. Treasury security with the maturity closest to and greater than such
Remaining Average Life and (2) the actively traded U.S. Treasury security with
the maturity closest to and less than such Remaining Average Life. The
Reinvestment Yield shall be rounded to the number of decimal places as appears
in the interest rate of the applicable Bond of the Series 2014.
“Remaining Average Life” means, with respect to any Called Principal, the number
of years (calculated to the nearest one‑twelfth year) obtained by dividing
(i) such Called Principal into (ii) the sum of the products obtained by
multiplying (a) the principal component of each Remaining Scheduled Payment with
respect to such Called Principal by (b) the number of years (calculated to the
nearest one‑twelfth year) that will elapse between the Settlement Date with
respect to such Called Principal and the scheduled due date of such Remaining
Scheduled Payment.
“Remaining Scheduled Payments” means, with respect to the Called Principal of
any Bond of the Series 2014, all payments of such Called Principal and interest
thereon that would be due after the Settlement Date with respect to such Called
Principal if no payment of such Called Principal were made prior to its
scheduled due date, provided that if such Settlement Date is not a date on which
interest payments are due to be made under the terms of the Bonds of the
Series 2014, then (for the purpose of this calculation) the amount of the next
succeeding scheduled interest payment will be reduced by the amount of interest
accrued to such Settlement Date and required to be paid on such Settlement Date.
“Senior Financial Officer” means the chief financial officer, principal
accounting officer, treasurer or controller of the Company.
“Settlement Date” means, with respect to the Called Principal of any Bond of the
Series 2014, the date on which the principal of such Bonds is to be prepaid
pursuant to subsection (a) of this Section 2.3 or is declared to be immediately
due and payable pursuant to Article XI of the Indenture, as the context
requires.
Section 2.4.    The Company will not and will not permit any Affiliate to
purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of
the outstanding Bonds of the Series 2014 except upon the payment or prepayment
of the Bonds of the Series 2014 in accordance with the terms of this Second
Supplemental Indenture and the Bonds of the Series 2014. The Company will

-19-

--------------------------------------------------------------------------------

promptly cancel all Bonds of the Series 2014 acquired by it or any Affiliate
pursuant to any payment or prepayment of Bonds pursuant to any provision of this
Second Supplemental Indenture and no Bonds may be issued in substitution or
exchange for any such Bonds of the Series 2014.
Section 2.5.    Subject to the provisions of Section 15.02 of the Indenture, all
monies paid to the Trustee pursuant to Sections 2.2 and 2.3 of this Article II
shall be held by the Trustee in trust for the benefit of the respective
registered owners of the Bonds of the Series 2014 which are to be redeemed (in
whole or in part) and shall be paid to them as provided in Article IX of the
Indenture.
Section 2.6.    Nothing contained in the Indenture or in any Bond shall be
construed to imply any obligation upon the Trustee to make any payment, except
out of monies deposited with it for such purpose by the Company.
ARTICLE III
CERTAIN COVENANTS AND EVENTS OF DEFAULT    
Section 3.1.     The Company hereby covenants that, so long as any of the Bonds
of the Series 2014 shall remain outstanding, the covenants and agreements of the
Company set forth in Section 10.07 of the Indenture shall be and remain in full
force and effect, and be observed and complied with by the Company, with the

become (including by virtue of being owned or controlled by a Blocked Person (as

Nations or by the European Union, or (b) directly or indirectly to have any
investment in or engage in any dealing or transaction (including, without
limitation, any investment, dealing or transaction involving the proceeds of the

Series 2014 to be in violation of any law or regulation applicable to such
purchaser or holder, or (ii) is prohibited by or subject to sanctions under any
U.S. Economic Sanctions (as such term is defined in the Bond Purchase

-20-

Section 3.3.    So long as any Bonds of the Series 2014 are outstanding, unless
waived by the registered owners of at least a majority in principal amount of
the Bonds of the Series 2014 then outstanding, the Company shall perform or

dated as of June 30, 2014 (the “Bond Purchase Agreement”) pursuant to which the

have the following Events of Default in replacement of the Events of Default set

-21-

--------------------------------------------------------------------------------

written notice of such Event of Default to the Company with respect thereto,

Exclusive Benefit Covenants shall be deemed to be conferred upon Persons other

Company.
