remedies under this Agreement shall survive.
(c) Provided that the Company shall have delivered written notice thereof to the Bank

payment in full of all outstanding Reimbursement Obligations, together with accrued and unpaid
interest thereon, (ii) the cancellation and return of the Letter of Credit, (iii) the payment in full of

to pay to the Bank certain fees in such amounts and payable on such terms as set forth in the Fee
Letter.
SECTION 2.04. Reimbursement Obligations. The Company shall reimburse the
Bank for the full amount of each payment by the Bank under the Letter of Credit, including,
without limitation, amounts in respect of any reinstatement of interest on the Bonds at the
election of the Bank notwithstanding any failure by the Company to reimburse the Bank for any
previous drawing to pay interest on the Bonds (such obligation to reimburse the Bank being a
“Reimbursement Obligation”). The Company agrees to pay or cause to have paid to the Bank,
after the honoring by the Bank of any drawing under the Letter of Credit giving rise to a
Reimbursement Obligation, such Reimbursement Obligation no later than 4:00 P.M. (i) on the
date of such drawing, in the case of all drawings other than any Tender Drawing, and (ii) in the

to time plus the Applicable Margin, payable quarterly in arrears on the last day of each March,
June, September and December and on the earlier to occur of the date the principal amount of
such Reimbursement Obligation is payable and on the date such Reimbursement Obligation is
paid. To the extent that the Bank receives interest payable on account of any Pledged Bond such
interest received shall be applied and credited against accrued and unpaid interest on the
Reimbursement Obligations in respect of the Tender Drawing pursuant to which such Pledged
Bond was purchased.
(b) Notwithstanding any provision to the contrary herein, the Company shall pay
interest on all past-due amounts of principal and (to the fullest extent permitted by law) interest,
costs, fees and expenses hereunder or under any other Credit Document, from the date when
such amounts became due until paid in full, payable on demand, at the Default Rate in effect
from time to time.

determined by the Bank for purposes of this Section 2.05.
SECTION 2.06. Prepayments.
(a) The Company may, upon notice given to the Bank prior to 11:00 A.M., on any
Business Day, prepay without premium or penalty the outstanding amount of any
Reimbursement Obligation in respect of a Tender Drawing in whole or in part with accrued
interest to the date of such prepayment on the amount prepaid; provided, however, that each
partial prepayment shall be in an aggregate principal amount not less than $10,000,000 (or, if
lower, the principal amount outstanding hereunder on the date of such prepayment) or an integral
multiple of $5,000,000 in excess thereof.
(b) Prior to or simultaneously with the receipt of proceeds related to the remarketing
of Bonds purchased pursuant to one or more Tender Drawings, the Company shall directly, or
through the Remarketing Agent, the Trustee or the Paying Agent on behalf of the Company,
repay or prepay (as the case may be) the then-outstanding Reimbursement Obligations (in the
order in which they were incurred) by paying to the Bank an amount equal to the sum of (i) the
aggregate principal amount of the Bonds remarketed plus (ii) all accrued interest on the principal
amount of such Reimbursement Obligations so repaid or prepaid.
SECTION 2.07. Yield Protection. If, due to any Change in Law, there shall be
14

(A) an imposition of, or increase in, any reserve, assessment, insurance
charge, special deposit or similar requirement against letters of credit issued by, or
assets held by, deposits in or for the account of, or credit extended by, the Bank or
any Applicable Booking Office, or
(B) an imposition of any other condition the result of which is to
increase the cost to the Bank or any Applicable Booking Office of issuing the
Letter of Credit or making, funding or maintaining loans, or reduce any amount
receivable by the Bank or any Applicable Booking Office in connection with
letters of credit, the Reimbursement Obligations, or require the Bank or any
Applicable Booking Office to make any payment calculated by reference to the
amount of letters of credit, the Reimbursement Obligations held or interest
received by it, by an amount deemed material by the Bank or any Applicable
Booking Office,
then, upon demand by the Bank, the Company shall pay the Bank that portion of such increased
expense incurred or reduction in an amount received which the Bank determines is attributable to
issuing the Letter of Credit or making, funding and maintaining any Reimbursement Obligation
hereunder or its Commitment.
SECTION 2.08. Changes in Capital Adequacy Regulations. If the Bank determines
the amount of capital required or expected to be maintained by the Bank or any Applicable
Booking Office or any corporation controlling the Bank is increased as a result of any Change in
Law, then, upon demand by the Bank, the Company shall pay the Bank the amount necessary to
compensate for any shortfall in the rate of return on the portion of such increased capital which
the Bank determines is attributable to this Agreement, the Letter of Credit, its Commitment, any
Reimbursement Obligation (or any participations therein or in the Letter of Credit) (after taking
into account the Bank’s policies as to capital adequacy).
SECTION 2.09. Payments and Computations. Other than payments made pursuant
to Section 2.04, the Company shall make each payment hereunder not later than 12:00 noon on
the day when due in lawful money of the United States of America to the Bank at the address
listed below its name on its signature page hereto in same day funds. Computations of the Base
Rate (when based on the Federal Funds Rate or One-Month LIBOR) and the Default Rate (when
based on the Federal Funds Rate or One-Month LIBOR) shall be made by the Bank on the basis
of a year of 360 days for the actual number of days (including the first day but excluding the last
day) elapsed, and computations of the Base Rate (when based on the Prime Rate) and the Default
Rate (when based on the Prime Rate) shall be made by the Bank on the basis of a year of 365 or
366 days, as the case may be, for the actual number of days (including the first day but excluding
the last day) elapsed.
SECTION 2.10. Non-Business Days. Whenever any payment to be made hereunder
shall be stated to be due on a day that is not a Business Day such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be included in the
computation of payment of interest or fees, as the case may be.
15

SECTION 2.11. Source of Funds. All payments made by the Bank pursuant to the
Letter of Credit shall be made from funds of the Bank and not from funds obtained from any
other Person.
SECTION 2.12. Extension of the Stated Expiration Date. Unless the Letter of Credit
shall have expired in accordance with its terms on the Cancellation Date, at least 90 but not more
than 365 days before the Stated Expiration Date, the Company may request the Bank, by notice
to the Bank in writing (each such request being irrevocable), to extend the Stated Expiration
Date. If the Company shall make such a request, the Bank, in its sole discretion, may elect to
extend the Stated Expiration Date then in effect, and in such event the Bank shall deliver to the
Company a notice (herein referred to as a “Notice of Extension”) designating the date to which
the Stated Expiration Date will be extended and the conditions of such consent (including,
without limitation, conditions relating to legal documentation and the consent of the Trustee). If
all such conditions are satisfied and such extension of the Stated Expiration Date shall be
effective (which effective date shall occur on the Business Day following the date of delivery by
the Bank to the Trustee of an Extension Certificate (“Extension Certificate”) in the form of
Exhibit 8 to the Letter of Credit designating the date to which the Stated Expiration Date will be
extended), thereafter all references in any Credit Document to the Stated Expiration Date shall be
deemed to be references to the date designated as such in such legal documentation and the most
recent Extension Certificate delivered to the Trustee. Any date to which the Stated Expiration
Date has been extended in accordance with this Section 2.12 may be further extended, in like
manner, for such period as the Bank agrees to, in its sole discretion. Failure of the Bank to
deliver a Notice of Extension as herein provided within 30 days of a request by the Company to
extend such Stated Expiration Date shall constitute an election by the Bank not to extend the
Stated Expiration Date.
SECTION 2.13. Amendments Upon Extension. Upon any request for an extension of
the Stated Expiration Date pursuant to Section 2.12 of this Agreement, the Bank reserves the
right to renegotiate any provision hereof, and any such change shall be effected by an
amendment pursuant to Section 7.01; provided, however, that in such case, the Extension
Certificate shall not be delivered to the Trustee until the Bank and the Company have executed
such amendment.
SECTION 2.14. Evidence of Debt. The Bank shall maintain, in accordance with its
usual practice, an account or accounts evidencing the indebtedness of the Company resulting
from each drawing under the Letter of Credit, from each Reimbursement Obligation incurred
from time to time hereunder and the amounts of principal and interest payable and paid from
time to time hereunder. In any legal action or proceeding in respect of this Agreement, the
entries made in such account or accounts shall, in the absence of manifest error, be conclusive
evidence of the existence and amounts of the obligations of the Company therein recorded.
SECTION 2.15. Obligations Absolute. The payment obligations of the Company
under this Agreement shall be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances, including, without
limitation, the following circumstances:
16

(a) any lack of validity or enforceability of the Letter of Credit, any Credit Document,
any Related Document or any other agreement or instrument relating thereto;
(b) any amendment or waiver of or any consent to departure from all or any of any
Credit Document or any Related Document;
(c) the existence of any claim, set-off, defense or other right that the Company may
have at any time against the Trustee or any other beneficiary, or any transferee, of the Letter of
Credit (or any persons or entities for whom the Trustee, any such beneficiary or any such
transferee may be acting), the Bank, or any other person or entity, whether in connection with
any Credit Document, the transactions contemplated herein or therein or in the Related
Documents, or any unrelated transaction;
(d) any statement or any other document presented under the Letter of Credit proving
to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being
untrue or inaccurate in any respect;
(e) payment by the Bank under the Letter of Credit against presentation of a
certificate which does not comply with the terms of the Letter of Credit; or
(f) any other circumstance or happening whatsoever, including, without limitation,
any other circumstance which might otherwise constitute a defense available to or discharge of
the Company, whether or not similar to any of the foregoing.
Nothing in this Section 2.15 is intended to limit any liability of the Bank pursuant to Section 7.06
of this Agreement in respect of its willful misconduct or gross negligence as determined by a
court of competent jurisdiction by final and nonappealable judgment.
SECTION 2.16. Taxes.
(a) All payments made by the Company under this Agreement shall be made free and
clear of, and without deduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding, in the case of the Bank, taxes imposed on its overall net income, and
franchise taxes imposed on it by the jurisdiction under the laws of which the Bank (as the case
may be) is organized or any political subdivision thereof and, in the case of the Bank, taxes
imposed on its overall net income, and franchise taxes imposed on it by the jurisdiction of the
Bank’s Applicable Booking Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred
to as “Taxes”). If any Taxes are required to be withheld from any amounts payable to the Bank
hereunder, the amounts so payable to the Bank shall be increased to the extent necessary to yield
to the Bank (after payment of all Taxes) interest or any such other amounts payable hereunder at
the rates or in the amounts specified in this Agreement. Whenever any Taxes are payable by the
Company, as promptly as possible thereafter the Company shall send to the Bank a certified copy
of an original official receipt received by the Company showing payment thereof. If the
Company fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to
the Bank the required receipts or other required documentary evidence, the Company shall
17

indemnify the Bank for any incremental taxes, interest or penalties that may become payable by
the Bank as a result of any such failure. The agreements in this Section shall survive the
termination of this Agreement and the payment of the obligations hereunder and all other
amounts payable hereunder.
(b) The Bank agrees that it will deliver to the Company on or before the date hereof
two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI
or successor applicable form, as the case may be. The Bank also agrees to deliver to the
Company two further copies of said Form W-8BEN or W-8ECI or successor applicable forms or
other manner of certification, as the case may be, on or before the date that any such form
previously delivered expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form previously delivered by it to the Company, and such extensions
or renewals thereof as may reasonably be requested by the Company, unless in any such case an
event (including, without limitation, any change in treaty, law or regulation) has occurred prior
to the date on which any such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent the Bank from duly completing and delivering any such
form with respect to it and so advises the Company. The Bank shall certify that it is entitled to
receive payments under this Agreement without deduction or withholding of any United States
federal income taxes and that it is entitled to an exemption from United States backup
withholding tax.
(c) If the Bank shall request compensation for costs pursuant to this Section 2.16,
(i) the Bank shall make reasonable efforts (which shall not require the Bank to incur a loss or
unreimbursed cost or otherwise suffer any disadvantage deemed by it to be significant) to make
within 30 days an assignment of its rights and delegation and transfer of its obligations hereunder
to another of its offices, branches or affiliates, if, in its sole discretion exercised in good faith, it
determines that such assignment would reduce such costs in the future, (ii) the Company, may
with the consent of the Bank, which consent shall not be unreasonably withheld, secure a
substitute bank to replace the Bank, which substitute bank shall, upon execution of a counterpart
of this Agreement and payment to the Bank of any and all amounts due under this Agreement, be
deemed to be the Bank hereunder (any such substitution referred to in clause (ii) shall be
accompanied by an amount equal to any loss or reasonable expense incurred by the Bank as a
result of such substitution); provided that this Section 2.16(c) shall not be construed as limiting
the liability of the Company to indemnify or reimburse the Bank for any costs or expenses the
Company is required hereunder to indemnify or reimburse.

the Company or any of its Material Subsidiaries is a party or by which any of its or their
respective properties is bound or (iii) result in the creation or imposition of any Lien on the
property of the Company or any of its Material Subsidiaries other than Permitted Liens and Liens
required under this Agreement, except to the extent such conflict, breach or default referred to in
the preceding clause (ii), individually or in the aggregate, would not reasonably be expected to
have a Material Adverse Effect.
(e) Enforceability. Each Credit Document and each such Related Document is the
legal, valid and binding obligation of the Company enforceable in accordance with its terms,
except as limited by bankruptcy and similar laws affecting the enforcement of creditors’ rights
generally and by the application of general equitable principles.
(f) Compliance with Laws. The Company and each Material Subsidiary are in
compliance with all Applicable Laws (including Environmental Laws), except to the extent that
failure to comply would not reasonably be expected to have a Material Adverse Effect.
(g) Litigation. There is no action, suit, proceeding, claim or dispute pending or, to the
Company’s knowledge, threatened against or affecting the Company or any of its Material
Subsidiaries, or any of its or their respective properties or assets, before any Governmental
Authority that, individually or in the aggregate, could reasonably be expected to have a Material
Adverse Effect. There is no injunction, writ, preliminary restraining order or any other order of
any nature issued by any Governmental Authority directing that any material aspect of the
transactions expressly provided for in any of the Credit Documents or the Related Documents to
which the Company is a party not be consummated as herein or therein provided.

Consolidated Subsidiaries as at December 31, 2012, and the related consolidated statements of
income, cash flows and stockholders’ equity for the fiscal year ended on such date, certified by
Deloitte & Touche LLP, copies of which have heretofore been furnished to the Bank, present
fairly in all material respects the financial condition of the Company and its Consolidated
Subsidiaries as at such date, and the consolidated results of their operations and cash flows for
the fiscal year then ended. All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as may be disclosed therein).
(i) Material Adverse Effect. Since December 31, 2012, no event has occurred that

and have paid all taxes shown to be due and payable on said returns or on any assessments made
against it or any of its property; other than (i) with respect to taxes the amount or validity of
22

which is currently being contested in good faith by appropriate proceedings and with respect to
which reserves in conformity with GAAP have been provided on the books of the Company or
the applicable Material Subsidiary, as the case may be, or (ii) to the extent that the failure to do
so could not reasonably be expected to result in a Material Adverse Effect.

individually or in the aggregate, be reasonably expected to have a Material Adverse Effect.
There are no actions, suits or claims pending against or involving a Pension Plan (other than
routine claims for benefits) or, to the knowledge of the Company or any of its ERISA Affiliates,
threatened, that would reasonably be expected to be asserted successfully against any Pension
Plan and, if so asserted successfully, would reasonably be expected either singly or in the
aggregate to have a Material Adverse Effect. No lien imposed under the Internal Revenue Code
or ERISA on the assets of the Company or any of its ERISA Affiliates exists or is likely to arise
with respect to any Pension Plan. The Company and each of its Subsidiaries have complied with
foreign law applicable to its Foreign Plans, except to the extent that failure to comply would not
reasonably be expected to have a Material Adverse Effect.

for the purpose of buying or carrying Margin Stock, and no proceeds of the Bonds or the Letter
of Credit will be used to buy or carry any Margin Stock or to extend credit to others for the
purpose of buying or carrying any Margin Stock. After applying the proceeds of the Bonds and
the issuance of the Letter of Credit, not more than 25% of the assets of the Company and the
Material Subsidiaries that are subject to the restrictions of Section 5.03(a) or (c) constitute

litigation, notices of violation or liability, administrative proceedings, judgments or orders,
whether asserted, pending or threatened, relating to any liability under or compliance with any
applicable Environmental Law, against the Company or any Material Subsidiary or relating to
any real property currently or formerly owned, leased or operated by the Company or any
Material Subsidiary, that would reasonably be expected to have a Material Adverse Effect. No
Hazardous Materials have been or are present or are being spilled, discharged or released on, in,
under or from property (real, personal or mixed) currently or formerly owned, leased or operated
by the Company or any Material Subsidiary in any quantity or manner violating, or resulting in
liability under, any applicable Environmental Law, which violation or liability would reasonably
be expected to have a Material Adverse Effect.
(o) Accuracy of Information. No written statement or information furnished by or on
behalf of the Company to the Bank in connection with the negotiation, execution and closing of
this Agreement and the Custodian Agreement (including, without limitation, the Reoffering
Circular) or delivered pursuant hereto or thereto, in each case as of the date such statement or
information is made or delivered, as applicable, contained or contains, any material misstatement

of the Bank Secrecy Act and all rules regulations issued pursuant to it and (iii) applicable

conditions contained in each such Related Document on its part to be performed or observed, and
no Default has occurred and is continuing.
(s) Bonds Validly Issued. The Bonds have been duly authorized, authenticated and
issued and delivered and are not in default. The Bonds are the legal, valid and binding
obligations of the Issuer.
(t) Reoffering Circular. Except for information contained in the Reoffering Circular
furnished in writing by or on behalf of the Issuer, the Trustee, the Paying Agent, the
Remarketing Agent or the Bank specifically for inclusion therein, the Reoffering Circular, and
any supplement or “sticker” thereto, are accurate in all material respects for the purposes for
which their use shall be authorized; and the Reoffering Circular and any supplement or “sticker”
thereto, when read together as a whole, does not, as of the date of the Reoffering Circular or such
supplement or “sticker,” contain any untrue statement of a material fact or omit to state any
material fact necessary to make the statements made therein, in the light of the circumstances
under which they are or were made, not misleading.
(u) Taxability. The performance of this Agreement and the transactions contemplated
herein will not affect the status of the interest on the Bonds as exempt from Federal income tax.
(v) No Material Misstatements. The reports, financial statements and other written
information furnished by or on behalf of the Company to the Bank pursuant to or in connection
with this Agreement and the transactions contemplated hereby do not contain and will not

and no delay in exercising, any right hereunder or under any other Credit Document shall operate
as a waiver thereof; nor shall any single or partial exercise of any right hereunder or thereunder

herein provided are cumulative and not exclusive of any remedies provided by law.
SECTION 7.04. Set-off. Upon the occurrence and during the continuance of any

extent permitted by law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any time owing by the
Bank to or for the credit or the account of the Company against any and all of the obligations of

SECTION 7.05. Indemnification. The Company hereby indemnifies and holds the
Bank and each of its Affiliates and their respective officers, directors, employees, agents and

any and all claims, damages, losses, liabilities, costs and expenses (including, without limitation,
reasonable fees and expenses of counsel) which such Indemnified Party may incur or which may
be claimed against such Indemnified Party by any Person:
(a) by reason of any inaccuracy or alleged inaccuracy in any material respect, or any
untrue statement or alleged untrue statement of any material fact, contained in the Reoffering
Circular or any amendment or supplement thereto, except to the extent contained in or arising
from information in the Reoffering Circular (or any amendment or supplement thereto) supplied
in writing by and describing the Bank; or by reason of the omission or alleged omission to state
therein a material fact necessary to make such statements, in the light of the circumstances under
which they were made, not misleading; or
(b) by reason of or in connection with the execution, delivery or performance of this
Agreement, the other Credit Documents or the Related Documents, or any transaction
contemplated by this Agreement, the other Credit Documents or the Related Documents, other
than as specified in subsection (c) below; or
(c) by reason of or in connection with the execution and delivery or transfer of, or
payment or failure to make payment under, the Letter of Credit; provided, however, that the
Company shall not be required to indemnify any such party pursuant to this Section 7.05(c) for
any claims, damages, losses, liabilities, costs or expenses to the extent caused, as determined by
a court of competent jurisdiction by final and nonappealable judgment, by (i) the Bank’s willful
misconduct or gross negligence in determining whether documents presented under the Letter of
Credit comply with terms of the Letter of Credit or (ii) the Bank’s willful or grossly negligent
failure to make lawful payment under the Letter of Credit after the presentation to it by the
Trustee under the Indenture of a certificate strictly complying with the terms and conditions of
the Letter of Credit.
34

Nothing in this Section 7.05 is intended to limit the Company’s obligations contained in
Article II. Without prejudice to the survival of any other obligation of the Company hereunder or
under any other Credit Document, the indemnities and obligations of the Company contained in
this Section 7.05 shall survive the payment in full of amounts payable pursuant to Article II, and
the termination of the Letter of Credit.
SECTION 7.06. Liability of the Bank. The Company assumes all risks of the acts or
omissions of the Trustee, the Paying Agent and any other beneficiary or transferee of the Letter
of Credit with respect to its use of the Letter of Credit. Neither the Bank, nor any of its officers
or directors, shall be liable or responsible for: (a) the use which may be made of the Letter of
Credit or any acts or omissions of the Trustee, the Paying Agent and any other beneficiary or
transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or
of any endorsement thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by the Bank against presentation of
documents which do not comply with the terms of the Letter of Credit, including failure of any
documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other
circumstances whatsoever in making or failing to make payment under the Letter of Credit,
except that the Company shall have a claim against the Bank and the Bank shall be liable to the
Company, to the extent of any direct, as opposed to consequential, damages suffered by the
Company which the Company proves, in a court of competent jurisdiction by final and
nonappealable judgment, were caused by (i) the Bank’s willful misconduct or gross negligence
in determining whether documents presented under the Letter of Credit are genuine or comply
with the terms of the Letter of Credit or (ii) the Bank’s willful or grossly negligent failure to
make lawful payment under the Letter of Credit after the presentation to it by the Trustee or the
Paying Agent under the Indenture of a certificate strictly complying with the terms and
conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, the Bank
may accept original or facsimile (including telecopy) certificates presented under the Letter of
Credit that appear on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.
SECTION 7.07. Costs, Expenses and Taxes.
The Company agrees to pay on demand all reasonable out-of-pocket costs and expenses
in connection with the preparation, issuance, delivery, filing, recording, and administration of
this Agreement, the Letter of Credit, the other Credit Documents and any other documents which
may be delivered in connection with the Credit Documents, including, without limitation, the
reasonable fees and out-of-pocket expenses of counsel for the Bank incurred in connection with
the preparation and negotiation of this Agreement, the Letter of Credit and any other Credit
Documents and any document delivered in connection therewith and all costs and expenses
incurred by the Bank (including reasonable fees and out-of-pocket expenses of counsel) in
connection with (i) the transfer, drawing upon, change in terms, maintenance, amendment,
renewal or cancellation of the Letter of Credit, (ii) any and all amounts which the Bank has paid
relative to the Bank’s curing of any Event of Default resulting from the acts or omissions of the
Company under this Agreement, any other Credit Document or any Related Document, (iii) the
enforcement of, or protection of rights under, this Agreement, any other Credit Document or any
Related Document (whether through negotiations, legal proceedings or otherwise), (iv) any
action or proceeding relating to a court order, injunction, or other process or decree restraining or
35

seeking to restrain the Bank from paying any amount under the Letter of Credit or (v) any
waivers or consents or amendments to or in respect of this Agreement, the Letter of Credit or any
other Credit Document requested by the Company. In addition, the Company shall pay any and
all stamp and other taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of this Agreement, the Letter of Credit, any other Credit
Documents or any of such other documents (“Other Taxes”), and agrees to save the Bank
harmless from and against any and all liabilities with respect to or resulting from any delay in
paying or omission to pay such Other Taxes.
SECTION 7.08. Binding Effect. This Agreement shall become effective when it shall
have been executed and delivered by the Company and the Bank and thereafter shall (a) be
binding upon the Company and its successors and assigns, and (b) inure to the benefit of and be
enforceable by the Bank and each of its successors, transferees and assigns; provided that, the
Company may not assign all or any part of its rights or obligations under any Credit Document
without the prior written consent of the Bank.
SECTION 7.09. Assignments and Participation.
(a) The Bank may assign to one or more banks, financial institutions or other entities
(each a “Bank Assignee”) all of its rights and obligations under this Agreement, the other Credit
Documents and the Related Documents (including, without limitation, all of its Commitment and
the Reimbursement Obligations owing to it); provided, however, that (i) the Company (unless an
Event of Default shall have occurred and be continuing or such assignment is to an Affiliate of
the Bank) shall have consented to such assignment (which consent shall not be unreasonably
withheld or delayed) by signing the Assignment and Assumption referred to in clause (ii) below,
and (ii) the parties to each such assignment shall execute and deliver to the Bank, for its
acceptance and recording in the Register (as defined in Section 7.09(c)), an Assignment and
Assumption. Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Assumption, (x) the Bank Assignee thereunder
shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned
to it pursuant to such Assignment and Assumption, have the rights and obligations of the Bank
hereunder and (y) the Bank as assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Assumption, relinquish its
rights and be released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption covering all or the remaining portion of the Bank’s rights and
obligations under this Agreement, the Bank shall cease to be a party hereto). Notwithstanding
anything to the contrary contained in this Agreement, the Bank may at any time assign all or any
portion of the demand loans owing to it to any Affiliate of the Bank. No such assignment
referred to in the preceding sentence, other than to an Affiliate of the Bank consented to by the
Company (such consent not to be unreasonably withheld or delayed), shall release the Bank from
its obligations hereunder. Nothing contained in this Section 7.09 shall be construed to relieve the
Bank of any of its obligations under the Letter of Credit, other than as contemplated in the last
sentence of Section 7.09(h).
(b) By executing and delivering an Assignment and Assumption, the Bank as assignor
thereunder and the Bank Assignee thereunder confirm to and agree with each other and the other
parties hereto as follows: (i) other than as provided in such Assignment and Assumption, the
36

Bank as assignor thereunder makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in or in connection with this
Agreement, any other Credit Document or any Related Document or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Credit
Document or any Related Document or any other instrument or document furnished pursuant
hereto; (ii) the Bank as assignor thereunder makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Company or the performance or
observance by the Company of any of its obligations under this Agreement, any other Credit
Document or any Related Document or any other instrument or document furnished pursuant
hereto or thereto; (iii) such Bank Assignee confirms that it has received a copy of each Credit
Document, together with copies of the financial statements referred to in Section 5.01(h) of this
Agreement and such other documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into such Assignment and Assumption; (iv) such Bank
Assignee will, independently and without reliance upon the Bank as Assignor and based on such
documents and information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under the Credit Documents; and (v) such Bank
Assignee agrees that it will perform in accordance with their terms all of the obligations which
by the terms of the Credit Documents are required to be performed by it as Assignee of the Bank.
(c) The Bank shall maintain at the address listed below its name on its signature page
hereto a copy of each Assignment and Assumption delivered to and accepted by it and a register
for the recordation of the names and addresses of the Bank Assignees and the Commitment of,
and principal amount of the Reimbursement Obligations owing to, each Bank Assignee from
time to time in such form as the Bank shall determine (the “Register”). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest error, and the
Company and the Bank may treat each Person whose name is recorded in the Register as a Bank
Assignee for all purposes of the Credit Documents. The Register shall be available for inspection
by the Company or the Bank or any Bank Assignee at any reasonable time and from time to time
upon reasonable prior notice.
(d) Upon its receipt of an Assignment and Assumption executed by the Bank and a
Bank Assignee, the Bank shall, if such Assignment and Assumption has been completed, and has
been signed by the Company (if the Company’s consent is required), (i) accept such Assignment
and Assumption, (ii) record the information contained therein in the Register and (iii) give
prompt notice of such recordation to the Company.
(e) The Bank may sell participations to one or more banks, financial institutions or
other entities (each a “Participant”) in all or a portion of its rights and obligations under this
Agreement, the other Credit Documents and the Related Documents (including, without
limitation, all or a portion of its Commitment and the Reimbursement Obligations owing to it);
provided, however, that (i) the Bank’s obligations under this Agreement (including, without
limitation, its Commitment to the Company hereunder) shall remain unchanged, (ii) the Bank
shall remain solely responsible to the other parties hereto for the performance of such
obligations, and (iii) the Company shall continue to deal solely and directly with such Bank in
connection with the Bank’s rights and obligations under this Agreement. Any agreement
pursuant to which the Bank may grant such a participating interest shall provide that the Bank
shall retain the sole right and responsibility to enforce the obligations of the Company hereunder
37

or under any other Credit Document including, without limitation, the right to approve any
amendment, modification or waiver of any provision of the Credit Documents; provided that
such participation agreement may provide that the Bank will not agree to any modification,
amendment or waiver of any Credit Document which would (a) waive, modify or eliminate any
of the conditions precedent specified in Article III, (b) increase or extend the Commitment of the
Bank or subject the Bank to any additional obligations, (c) forgive principal, interest, fees or
other amounts payable hereunder or under any other Credit Document or reduce the rate at which
interest or any fee is calculated, (d) postpone any date fixed for any payment of principal,
interest, fees or other amounts payable hereunder or under any other Credit Document, (e) or
waive any requirement for the release of collateral or (f) amend this Section 7.09(e).
(f) The Bank may, in connection with any assignment or participation or proposed
assignment or participation pursuant to this Section 7.09, disclose to the assignee or participant
or proposed assignee or participant, any information relating to the Company furnished to the
Bank by or on behalf of the Company; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree to preserve the confidentiality of any
confidential information relating to the Company received by it from the Bank.
(g) Anything in this Section 7.09 to the contrary notwithstanding, the Bank, any Bank
Assignee or any Participant may assign and pledge all or any portion of its Commitment and the
Reimbursement Obligations owing to it to any Federal Reserve Bank or any other central
banking authority (and its transferees) as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular issued by such
Federal Reserve Bank. No such assignment shall release the assigning or pledging entity from
its obligations hereunder.
(h) If the Bank, any Bank Assignee or Participant (the “Demanding Entity”) shall
make any demand for payment under Section 2.07 or 2.08, then within 30 days after any such
demand, the Company may, with the approval of the Bank (which approval shall not be
unreasonably withheld) and provided that no Event of Default or Default shall then have
occurred and be continuing, demand that such Demanding Entity assign in accordance with this
Section 7.09 to one or more assignees designated by the Company all (but not less than all) of
such Demanding Entity’s Commitment and the Reimbursement Obligations owing to it within
the period ending on such 30th day. If any such assignee designated by the Company shall fail
to consummate such assignment on terms acceptable to such Demanding Entity, or if the
Company shall fail to designate any such assignees for all or part of the Demanding Entity’s
Commitment or Reimbursement Obligations, then such demand by the Company shall become
ineffective; it being understood for purposes of this subsection (h) that such assignment shall be
conclusively deemed to be on terms acceptable to such Demanding Entity, and such Demanding
Entity shall be compelled to consummate such assignment to an assignee designated by the
Company, if such assignee (i) shall agree to such assignment by entering into an Assignment and
Assumption in substantially the form of Exhibit C hereto with such Demanding Entity and
(ii) shall offer compensation to such Demanding Entity in an amount equal to all amounts then
owing by the Company to such Demanding Entity hereunder, whether for principal, interest,
fees, costs or expenses (other than the demanded payment referred to above and payable by the
Company as a condition to the Company’s right to demand such assignment), or otherwise.
Notwithstanding anything to the contrary in this Section, if the Company exercises its right to
38

demand the Bank to assign its Commitment and Reimbursement Obligations under this
subsection (h) while the Letter of Credit is outstanding, on the date such assignment becomes
effective, (i) the Bank Assignee shall agree to assume all of the Bank’s Commitment and
Reimbursement Obligations pursuant to such assignment, (ii) the Bank Assignee shall issue a
replacement Letter of Credit in accordance with the terms of the Indenture, (iii) the Letter of
Credit issued by the Bank shall be terminated in accordance with its terms and surrendered to the
Bank, (iv) the Company shall pay to the Bank all amounts then due and payable to the Bank
hereunder and under the other Credit Documents and (v) the Bank shall cease to be a party
hereto.
SECTION 7.10. Severability. Any provision of this Agreement which is prohibited,
unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition, unenforceability or non-authorization without invalidating the
remaining provisions hereof or affecting the validity, enforceability or legality of such provision
in any other jurisdiction.

GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK.

Agreement and the other Related Documents to which it is a party, or for recognition and
enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the

mailing a copy thereof by registered or certified mail (or any substantially similar form of mail),
postage prepaid, to the Company at its address set forth in Section 7.02 of this Agreement or at
such other address of which the Bank shall have been notified pursuant thereto; and
(d) agrees that nothing herein shall affect the right to effect service of process in any
other manner permitted by law or shall limit the right to sue in any other jurisdiction.
This Section 7.13 shall not be construed to confer a benefit upon, or grant a right or privilege to,
any Person other than the parties hereto.
39

SECTION 7.14. Acknowledgments. The Company hereby acknowledges:
(a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement, the other Credit Documents and other Related Documents;

Form of Custodian Agreement
CUSTODIAN AGREEMENT
This CUSTODIAN AND PLEDGE AGREEMENT, dated as of March 26, 2013 (this
“Agreement”), is made by and among PACIFICORP, an Oregon corporation (the “Company”),
THE BANK OF NOVA SCOTIA (the “Bank”), and THE BANK OF NEW YORK MELLON
TRUST COMPANY, N.A. (“BNYM”), as the Trustee pursuant to the Indenture referred to
below, as custodian (the “Custodian”).
RECITALS
A. The Company and the Bank have entered into a Letter of Credit and
Reimbursement Agreement, dated as of March 26, 2013, relating to $9,335,000 Sweetwater
County, Wyoming Pollution Control Revenue Refunding Bonds (PacifiCorp Project) Series
1992A (as amended, restated, supplemented or otherwise modified from time to time, the
“Reimbursement Agreement”), pursuant to which the Bank has agreed to issue the Letter of
Credit (as defined in the Reimbursement Agreement) in favor of BNYM, as trustee (the
“Trustee”) under the Trust Indenture, dated as of September 1, 1992, as amended and restated by
a Third Supplemental Indenture, dated as of September 1, 2010 (as amended, restated,
supplemented or otherwise modified from time to time, the “Indenture”), between Sweetwater
County, Wyoming and the Trustee, for the account of the Company.
B. It is a condition precedent under the Reimbursement Agreement to the obligation
of the Bank to issue the Letter of Credit that the Company and the Custodian shall have executed
and delivered this Agreement.
AGREEMENT
The Company and the Custodian each agree with the Bank as follows:
SECTION 1. Defined Terms. Capitalized terms not defined herein shall have the
meanings ascribed to such terms in the Reimbursement Agreement or the Indenture, as
applicable.
SECTION 2. Pledge. The Company hereby pledges, assigns, transfers, hypothecates
and delivers to the Bank all of its right, title and interest in, and grants to the Bank a first-priority
Lien upon, (i) the Bonds purchased with moneys received under the Letter of Credit in
connection with a Tender Drawing and owned or held by the Company or an Affiliate of the
Company, or the Trustee (collectively, the “Pledged Bonds”) and (ii) all proceeds of the Pledged
Bonds (such proceeds, together with the Pledged Bonds, collectively, the “Collateral”), all as
collateral security for the prompt and complete payment when due of all amounts payable by the
Company to the Bank, and the prompt and complete performance of all other obligations of the
Company to the Bank, whether now existing or hereafter arising, under or in respect of the

Exhibit B
Page 2 of 11
Reimbursement Agreement, the Letter of Credit, this Agreement and the Related Documents
(collectively, the “Obligations”). The Company hereby agrees that the Custodian shall act as the
agent and bailee of the Bank for the purpose of perfecting the Lien of this Agreement and of
holding the Collateral for the benefit of the Bank pursuant to the Indenture. For so long as the
Pledged Bonds are registered in the name of The Depository Trust Company (“DTC”), the
Custodian shall cause DTC to make appropriate entries on its books increasing the appropriate
securities account of the Custodian, as a direct participant of DTC, to include the Pledged Bonds,
and shall identify, by book-entry or otherwise, the Pledged Bonds as belonging to, or subject to a
security interest in favor of, the Bank, and shall send the Bank a confirmation of the transfer of
the Pledged Bonds to the Bank. The Custodian shall continuously identify the Pledged Bonds on
its books as being held for the account of the Bank and shall take all such action reasonably
requested by the Bank to ensure that the Bank shall be the “entitlement holder” with respect to
the Pledged Bonds having “control” of all “security entitlements” related to the Pledged Bonds
within the meaning of Article 8 of the Uniform Commercial Code as in effect from time to time
in the State of New York (“UCC Article 8”).
SECTION 3. Payments on Collateral. If, while this Agreement is in effect, the
Company shall become entitled to receive or shall receive any interest or other payment in
respect of the Collateral, the Company agrees to accept the same as the Bank’s agent, to hold the
same in trust on behalf of the Bank and to deliver the same forthwith to the Bank. The Company
instructs and authorizes the Custodian to hold and receive on the Bank’s behalf and to deliver
forthwith to the Bank any payment received by it in respect of the Collateral (including, without
limitation, the proceeds of any remarketing of the Pledged Bonds). All such payments in respect
of the Collateral that are paid to the Bank shall be credited against the Obligations as provided in
the Reimbursement Agreement.
SECTION 4. Release of Pledged Bonds. To the extent that the Bank receives
reimbursement in cash (whether under the Reimbursement Agreement or the Indenture) of an
amount equal to the amount of any Tender Drawing related to the purchase of Pledged Bonds in
a manner that will permit the reinstatement of the Letter of Credit in respect of such Pledged
Bonds in accordance with the terms of the Letter of Credit, the Bank agrees to provide written
notice to the Trustee that the Letter of Credit has been irrevocably reinstated in an amount equal
to the amount of such Tender Drawing, whereupon the Bank agrees to release from the Lien of
this Agreement the corresponding principal amount of Pledged Bonds. The Bank instructs and
authorizes the Custodian upon such release of any Pledged Bonds from the Lien of this
Agreement, to cause DTC to make appropriate entries on its books decreasing the appropriate
securities account of the Custodian to exclude such Pledged Bonds and to reclassify, by book-
entry or otherwise, the Pledged Bonds as not subject to a security interest in favor of the Bank.
SECTION 5. Representations and Warranties. The Company represents and warrants
that: (a) on the date of delivery of the Pledged Bonds to or for the benefit of the Bank, to the
Company’s knowledge, no other Person shall have any right, title or interest in and to the
Pledged Bonds; (b) the Company has, and on the date of delivery to or for the benefit of the
Bank of any of the Pledged Bonds will have, full power, authority and legal right to pledge all of
its right, title and interest in and to the Pledged Bonds pursuant to this Agreement; (c) the pledge,
assignment and delivery of the Pledged Bonds pursuant to this Agreement will create a valid first
Lien on, and a perfected first-priority security interest in, all right, title and interest of the

Exhibit B
Page 3 of 11
Company in and to the Collateral, subject to no prior Lien on the property or assets of the
Company that would include the Pledged Bonds; and (d) the Company makes each of the
representations and warranties in the Reimbursement Agreement and Related Documents to and
for the benefit of the Bank as if the same were set forth in full herein. The Company shall be
deemed to have represented and warranted to the Bank on the date of each drawing under the
Letter of Credit that the statements contained herein are true and correct.
SECTION 6. Rights of the Bank. The Bank shall not be liable for any failure to collect
or realize upon all or any part of the Obligations or any collateral security (including, without
limitation, the Collateral) or guaranty for the Obligations, or for any delay in so doing, and the
Bank shall be under no obligation to take any action whatsoever with regard to the Obligations or
any such collateral security or guaranty. If an Event of Default has occurred and is continuing,
the Bank may, without notice, exercise all rights, privileges or options pertaining to any Pledged
Bonds as if it were the absolute owner of such Pledged Bonds, upon such terms and conditions as
it may determine, all without liability except to account for property actually received by it, but
the Bank shall have no duty to exercise any of those rights, privileges or options and shall not be
responsible for any failure to do so or delay in so doing.
SECTION 7. Remedies. In the event that any portion of the Obligations has been
declared due and payable after an Event of Default, the Bank may, without demand of
performance or other demand, advertisement or notice of any kind (except the notice specified
below of the time and place of public or private sale) to or upon the Company or any other
Person (all and each of which demands, advertisements or notices are hereby expressly waived),
in its sole discretion, (a) exercise any or all of its rights and remedies under the Reimbursement
Agreement, the Letter of Credit, this Agreement, the Related Documents and any other
instruments and agreements securing, evidencing or relating to the Obligations or under
applicable law (including, without limitation, all of the rights and remedies of a secured creditor
under the Uniform Commercial Code as in effect from time to time in the State of New York or
the commercial code of any other applicable jurisdiction), (b) forthwith collect, receive,
appropriate and realize upon all or any part of the Collateral, (c) forthwith sell, assign, give an
option or options to purchase, contract to sell or otherwise dispose of and deliver all or any part
of the Collateral in one or more parcels at public or private sale or sales, at any exchange,
broker’s board or at any of the Bank’s offices or elsewhere, upon such terms and conditions as it
may deem advisable and at such prices as it may deem best, for cash or on credit or for future
delivery without assumption of any credit risk, with the right to the Bank upon any such sale or
sales, public or private, to purchase the whole or any part of the Collateral so sold, free of any
right or equity of redemption in the Company, which right or equity is hereby expressly waived
or released, or (d) take all or any combination of the foregoing actions. The Bank acknowledges
that, and will use commercially reasonable efforts to notify prior to the date of any such sale,
assignment, or disposition and delivery, any purchaser of any Collateral consisting of Pledged
Bonds that, upon such selling, assigning or disposing of and delivery of any portion of such
Pledged Bonds, that such Pledged Bonds are unrated. After deducting all reasonable costs and
expenses of every kind incurred in taking any of the foregoing actions or incidental to the care,
safekeeping or otherwise of any and all of the Collateral or in any way relating to the rights of
the Bank hereunder, including, without limitation, reasonable attorneys’ fees and legal expenses,
after payment of all of the Obligations in such order as the Bank may elect (the Company
remaining liable to the extent provided under the Reimbursement Agreement for any deficiency

Exhibit B
Page 4 of 11
remaining unpaid after such application) and after payment by the Bank of any other amount
required or permitted by any provision of law, the Bank shall pay to the Company the surplus, if
any, of any amounts realized by the Bank under this Section 7 or such other Person entitled
thereto. The Company agrees that the Bank need not give more than 10 days’ notice of the time
and place of any public sale or of the time after which a private sale or other intended disposition
is to take place and that such notice is reasonable notification of such matters. No notification
need be given to the Company if it has signed after default a statement renouncing or modifying
any right to deficiency if the proceeds of any sale or other disposition of the Collateral are
insufficient to pay all amounts to which the Bank is entitled, including, without limitation, the
fees and costs of any attorneys employed by the Bank to collect such deficiency.
SECTION 8. No Disposition. The Company agrees that it will not sell, assign, transfer,
exchange or otherwise dispose of, or grant any option with respect to, the Collateral and that it
will not create, incur or permit to exist any Lien with respect to all or any part of the Collateral,
except for the Lien of this Agreement.
SECTION 9. Sale of Collateral.
(a) The Company recognizes that the Bank may be unable to effect a public sale of
any or all of the Pledged Bonds by reason of certain prohibitions contained in the Securities Act
of 1933, as amended (the “Securities Act”), and applicable state securities laws but may be
compelled to resort to one or more private sales to a restricted group of purchasers that will be
obliged to agree, among other things, to acquire such securities for their own account for
investment and not with a view to distribution or resale. The Company acknowledges and agrees
that any such private sale may result in prices and other terms less favorable to the seller than if
such sale were a public sale and, notwithstanding such circumstances, agrees that any such
private sale shall be deemed to have been made in a commercially reasonable manner. The Bank
shall be under no obligation to delay a sale of any of the Pledged Bonds for the period of time
necessary to permit the Issuer to register such securities for public sale under the Securities Act
or under applicable state securities laws, even if the Issuer would agree to do so.
(b) The Company further agrees to do or cause to be done all such other acts and
things as may be lawfully necessary to make such sale or sales of all or any part of the Pledged
Bonds valid and binding and in compliance with any and all applicable laws, rules, regulations,
orders or decrees, all at the Company’s expense. The Company further agrees that a breach of
any of the covenants contained in this Section 9 will cause irreparable injury to the Bank for
which the Bank would have no adequate remedy at law in respect of such breach and, as a
consequence, agrees that each and every covenant contained in this Section 9 shall be
specifically enforceable against the Company, and the Company waives and agrees not to assert
any defenses against an action for specific performance of such covenants except for a defense
that no Event of Default has occurred under the Reimbursement Agreement. The Company
further acknowledges the impossibility of ascertaining the amount of damages that would be
suffered by the Bank by reason of a breach of any of such covenants and, consequently, agrees
that, if the Bank shall sue for wages for breach, it shall pay, as liquidated damages and not as a
penalty, an amount equal to the principal of, and accrued interest on, the Pledged Bonds on the
date the Bank shall demand compliance with this Section 9.

Exhibit B

SECTION 10. Further Assurances. The Company agrees that at any time and from
time to time upon the written request of the Bank, the Company will execute and deliver such
further documents and do such further acts and things as the Bank may reasonably request in
order to effect the purposes of this Agreement.
SECTION 11. Collateral Agency Agreement.
(a) The Bank hereby appoints the Custodian as agent and bailee for the Bank on the
terms and conditions of this Section 11, and the Custodian hereby accepts such appointment and
agrees with the Bank to act as agent without compensation separate from that provided to the
Custodian pursuant to the Indenture.
(b) The duties of the Custodian as agent under this Agreement shall be as follows:
(i) the Custodian shall hold (either directly or as a direct participant of DTC)
in a securities account for the benefit of the Bank all Pledged Bonds purchased by the
Custodian with drawings under the Letter of Credit pursuant to the Indenture, all
proceeds thereof and all other amounts held by the Custodian and payable to the Bank
pursuant to the Indenture;
(ii) upon the remarketing of Pledged Bonds, the Custodian shall deliver to the
Bank the proceeds of such remarketing and all other amounts received by the Custodian
and payable to the Bank pursuant to the Indenture; and
(iii) the Custodian shall comply with any notice, request or instruction of the
Bank with respect to the Pledged Bonds, subject to Section 4 hereof, without the further
consent of the Company such that the Bank shall be deemed to have “control” of the
Pledged Bonds as “security entitlements” within the meaning of UCC Article 8.
(c) The Custodian shall not pledge, hypothecate, transfer or release all or any part of
the Collateral to any other Person or in any manner not in accordance with this Section 11
without the prior written consent of the Bank.
(d) The Custodian shall transfer the benefits or obligations of this Agreement or the
Indenture only with the prior written consent of the Bank and only if any such transferee shall
have agreed in writing to be bound by the terms and conditions of this Section 11 and the
Indenture. Notwithstanding the preceding sentence, any corporation, association or other entity
into which the Custodian may be converted or merged, or with which it may be consolidated, or
to which it may sell or otherwise transfer all or substantially all of its corporate trust assets and
business or any corporation, association or other entity resulting from any such conversion, sale,
merger, consolidation or other transfer to which it is a party, ipso facto, shall be and become
successor custodian hereunder, vested with all other matters as was its predecessor, without the
execution or filing of any instrument or consent or any further act on the part of the parties
hereto.
(e) Neither the Custodian nor any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be liable for any action lawfully taken or omitted to be taken
by it under or in connection with this Agreement (except for its own gross negligence or willful

Exhibit B
Page 6 of 11
misconduct). The Custodian undertakes to perform only such duties as are expressly set forth
herein. The Custodian may rely, and shall be protected in acting or refraining from acting, upon
any written notice, instruction or request furnished to it hereunder and believed by it to be
genuine and to have been signed or presented by the proper party. The Custodian shall have the
right to perform any of its duties hereunder through agents, attorneys, custodians or nominees,
and shall not be responsible for the misconduct or negligence of such agents, attorneys,
custodians and nominees appointed by it with due care. None of the provisions contained in this
Agreement shall require the Custodian to use or advance its own funds in the performance of any
of its duties or the exercise of any of its rights or powers hereunder. The Custodian may consult
with counsel of its own choice and shall have full and complete authorization and protection for
any action taken or suffered by it hereunder in good faith and in accordance with the opinion of
such counsel. Notwithstanding any provision to the contrary contained herein, the Custodian
shall not be relieved of liability arising in connection with its own gross negligence or willful
misconduct. The Company hereby agrees to indemnify, defend and hold harmless the Custodian
from and against all losses, damages, costs, charges, payments, liabilities and expenses,
including the costs of litigation, investigation and reasonable legal fees incurred by the Custodian
and arising directly or indirectly out of its role as Custodian pursuant to this Agreement, except
as caused by the Custodian’s willful misconduct or gross negligence.
SECTION 12. Notices. All notices, requests and other communications to any party
hereunder shall be in writing (including bank wire, telecopier, overnight courier or similar
writing) and shall be given to such party, addressed to it, at its address or telecopier number set
forth below or such other address or telecopier number as such party may specify by notice to the
