*   In the event that the Company does not have sufficient funds to make all or any part of this
principal payment or is precluded from making all or any part of the payment under the terms of the
Subordination Agreement, such failure shall not constitute a default or Event of Default on the
Bonds or under the Loan and Trust Agreement; provided, however, all such amounts not paid on
December 1, 2010 shall become due and payable on December 1, 2011 in addition to the other
principal due on such date.

     (b) Mandatory Redemption of Bonds on Completion Date. The Bonds will be subject
to redemption in part by lot (or such other random means selected by the Trustee) at a redemption
price equal to the principal amount thereof, together with accrued interest to the date of
redemption, from proceeds of the Bonds remaining after the Completion Date.

     (c) Optional Redemption or Purchase. The Bonds are subject to redemption or a
mandatory tender for purchase, at the option of the Company, on or after December 1, 2010 in whole
or in part on the redemption or purchase date established by the Trustee in accordance with this
Loan and Trust Agreement (but if in part in integral multiples of $5,000), at the redemption or
purchase prices (expressed in percentages of the principal amount of the Bonds called for
redemption or purchase) set forth below plus, in each case, accrued interest to the redemption or
purchase date:

	 	 	 	 	 
	Redemption or Purchase Dates	 	 
	    (both dates inclusive)	 	Redemption or Purchase Prices
	December 1, 2012 to November 30, 2013
	 	 	102	%
	December 1, 2013 to November 30, 1014
	 	 	101	%
	December 1, 2014 and thereafter
	 	 	100	%

     (d) Mandatory Redemption Upon Determination of Taxability. The Bonds are subject to
mandatory redemption in whole at a redemption price equal to 100% of the principal amount of the
Bonds to be redeemed plus accrued interest thereon to the Redemption Date upon the occurrence of a
Determination of Taxability on the Redemption Date established by the Trustee pursuant to Section
2.04; provided, however, if mandatory redemption on account of a Determination of Taxability of
less than all the Bonds would result, in the opinion of Bond Counsel, in the interest on the Bonds
Outstanding following such mandatory redemption not being

18

 

includable in the gross income of the
Owners of such Bonds Outstanding, then the Bonds are subject to mandatory redemption upon the
occurrence of a Determination of Taxability in the amount specified in such opinion.

     (e) Mandatory Redemption Upon Occurrence of Certain Extraordinary Events. The Bonds
shall be subject to redemption, in whole, at 100% of the principal amount to be redeemed plus
accrued interest to the Redemption Date on the Redemption Date established by the Trustee pursuant
to Section 2.04, if any of the following do not occur by September 30, 2006:

     (i) The Company shall have entered into a design/build contract with Fagen.

     (ii) The Company shall have closed its equity offering in an amount not less than
Thirty Three Million Six Hundred Sixty Two Thousand Five Hundred Dollars ($33,662,500.00).

     (iii) The Company shall have entered into and finalized any and all debt obligations
with the Senior Lender in an amount not less than $63,675,000.00; and

     (iv) Notwithstanding the foregoing, the combination of debt and equity must be not less
than $130,000,000.00.

     (f) Optional Redemption Upon Occurrence of Certain Extraordinary Events. The Bonds
shall be subject to redemption, in whole or in part, at 100% of the principal amount to be redeemed
plus accrued interest to the Redemption Date, at the option of the Company, on the Redemption Date
established by the Trustee pursuant to Section 2.04, out of Net Proceeds of an insurance or
condemnation award relating to destruction or damage or condemnation of all or any part of the
Facility and, if necessary, other Company funds, if:

     (i) The Facility shall have been damaged or destroyed to such extent that, in the
opinion of the Company expressed in a Company’s Certificate, or in the written opinion of an
Inspecting Engineer filed with the Issuer and the Trustee following such damage or
destruction (1) the completion of the Facility will be delayed for at least six months, (2)
it is not practicable or desirable to rebuild, repair or restore the Facility within a
period of six consecutive months following such damage or destruction, or (3) the Company is
or will be thereby prevented from carrying on its normal operations at the Facility for a
period of at least six consecutive months;

     (ii) Title to or the temporary use of all or substantially all of the Facility shall
have been taken under the exercise of the power of eminent domain by any Government
Authority to such extent that, in the opinion of the Company expressed in a Company’s
Certificate, or in the written opinion of an Inspecting Engineer filed with the Issuer and
the
Trustee (1) the completion of the Facility will be delayed for at least six months, or (2)
the Company is or will be thereby prevented from carrying on its normal operations at the
Facility for a period of at least six consecutive months;

     (iii) Any court or administrative body of competent jurisdiction shall enter a
judgment, order or decree requiring the Company to cease all or any substantial part of its
operations at the Facility to such extent that, in the opinion of the Company expressed in
the

19

 

Company’s Certificate, or in the written opinion of Counsel, filed with the Issuer and
the Trustee, the Company is or will be thereby prevented from carrying on its normal
operations at the Facility for a period of at least six consecutive months;

     (iv) As a result of any changes in the Constitution of Nebraska or the Constitution of
the United States of America or of legislative or administrative action (whether state or
federal) or by final decree, judgment or order of any court or administrative body (whether
state or federal), this Loan and Trust Agreement shall have become void or unenforceable or
impossible of performance in accordance with the intent and purposes of the parties as
expressed herein, or unreasonable burdens or excessive liabilities shall have been imposed
on the Issuer or the Company including without limitation federal, state or other ad
valorem, property, income or other taxes not being imposed on the date hereof; or

     (v) It shall subsequently be discovered that the Company’s title to the Facility shall
be materially defective, and the Company’s title to the Facility shall be lost by reason of
such defect.

     In any such case, the Company shall, to exercise its option hereunder, give notice to the
Issuer and the Trustee in writing of its intent to exercise its option and specifying the proposed
Redemption Date, within thirty (30) days following discovery of the event by the Company. The
exercise by the Company of its option to redeem the Bonds shall be binding on the Trustee. Within
sixty (60) days after the giving of notice as set forth above, the Company shall deposit with the
Trustee a sum sufficient, together with other funds held by the Trustee and available for such
purpose (i) to redeem all Bonds then Outstanding at a redemption price equal to the principal
amount thereof, (ii) to pay the interest which will become due on such Bonds to and including the
Redemption Date, and (iii) to pay all expenses of the Issuer and the Trustee accrued and to accrue
through the Redemption Date.

     (g) If the Bonds are redeemed in part pursuant to this Section, the aggregate principal amount
available for redemption shall be allocated by the Trustee among the various maturities in the
proportions (as nearly as practicable given the minimum authorized denomination) that the amount of
such maturity bears to the aggregate principal amount of all Outstanding Bonds, or, at the option
of the Company, the particular Bonds or portions thereof to be redeemed shall be selected by the
Trustee in inverse order of stated maturity. The Trustee shall select Bonds within a maturity by
lot or by such other random means as the Trustee shall determine in its discretion.

     Section 2.03. Purchase and Cancellation of Bonds. The Company shall have the right to
purchase any outstanding Bond and deliver it to
the Trustee for cancellation. Also, the Trustee may purchase any outstanding Bond for cancellation
in accordance with this Loan and Trust Agreement. Any such purchase and cancellation of a Bond
shall ipso facto reduce the unpaid principal balance of the Loan on the date of
such cancellation by an amount equal to the principal amount of such Bond. The reduction shall be
applied to the principal installment on the Loan having the same maturity as the Bond so purchased
and cancelled.

     Section 2.04. Notice of Redemption. Notice of redemption shall be mailed first-class
mail, postage prepaid, not less than thirty (30) and no more than sixty (60) days before the
Redemption Date to each Bondowner at his last address appearing on the Bond Register; except upon
the

20

 

declaration of the principal of all Bonds then Outstanding immediately due and payable under
Section 8.02. Failure to give any such notice by mailing, or any defect therein, shall not affect
the validity of any proceedings for the redemption of any other Bond.

     If, at the time of mailing of the notice of the optional redemption, there has not been
deposited with the Trustee monies sufficient to redeem all the Bonds then called for redemption,
the notice may state that it is conditional, that is, subject to the deposit of the redemption
monies with the Trustee not later than the opening of business on the Redemption Date of the Bonds
then being called. Such notice will be of no effect unless such monies are so deposited.

     All notices of redemption shall (i) identify the Bonds to be redeemed by name, CUSIP number,
if any, date of issue, interest rate, maturity date and any other descriptive information the
Trustee deems desirable to identify accurately the Bonds to be redeemed and, if only a portion of
some Bonds will be redeemed, their certificate numbers and the principal amount to be redeemed;
(ii) identify the Redemption Date; (iii) state the Redemption Price; (iv) state that interest on
the Bonds or the portions of them called for redemption will stop accruing from the Redemption Date
if funds sufficient for their redemption and available for that purpose are on deposit with the
Trustee on the Redemption Date; and (v) state that payment for the Bonds will be made on the
Redemption Date at the principal trust office of the Trustee during normal business hours upon the
surrender of the Bonds to be redeemed in whole or in part. If less than all Outstanding Bonds are
to be redeemed, the Bonds to be redeemed shall be identified by reference to the series
designation, date of issue, serial numbers, maturity dates and, in the case of Bonds to be redeemed
in part only, the portion thereof to be redeemed.

     A copy of each redemption notice shall also be sent, by registered or certified mail, to the
registered securities depositories and national information services that disseminate redemption
notices as the Trustee determines to be customary or appropriate.

     Section 2.05. Bonds to be Limited Obligations of the Issuer. The Bonds shall be
limited obligations of the Issuer payable by it solely from the Pledged Revenues. The Bonds shall
not constitute a debt or obligation of the Issuer, the County, the State of Nebraska or any
political subdivision thereof within the meaning of any State of Nebraska constitutional provision
or statutory limitation and shall not be a charge against their general credit or taxing powers.

     Section 2.06. Source of Payment. The principal of, premium, if any, and interest on
the Bonds shall be payable by the Issuer solely from the Pledged Revenues, which are hereby
specifically, irrevocably and exclusively pledged to the punctual payment of the principal of,
premium, if any, and interest on the Bonds, and which shall be used for no other purpose except as
otherwise expressly authorized herein.

     Section 2.07. Form of Bonds. The Bonds shall be issuable only as fully registered
Bonds substantially in the form set forth in Exhibit A attached hereto. The Bonds are issuable with
such appropriate insertions, omissions, substitutions and other variations as are required or
permitted by this Loan and Trust Agreement and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon, as may be required to comply with
the rules of any securities exchange, or as may, consistently herewith, be determined by the
officers executing such Bonds as evidenced by their execution of the Bonds. There may be printed
or otherwise reproduced on any Bond form (i) the legal opinion of Bond Counsel, (ii) customary
“back file

21

 

panel” summary information, (iii) restrictions on transfer in form approved by the
Trustee as required in particular instances, and (iv) any other information deemed necessary or
appropriate by the Issuer or the Trustee with the approval of Bond Counsel to give notice of
information to Bondowners.

     Section 2.08. Execution of Bonds. The Bonds shall be executed on behalf of the Issuer
by its Chairperson under the official seal (if any) of the Issuer attested to by its Secretary.
The signatures of the Chairperson and Secretary on the Bonds may be manual or facsimile. The
official seal (if any) of the Issuer on the Bonds may be actually impressed or imprinted or may be
reproduced thereon by facsimile.

     Bonds bearing the manual or facsimile signatures of the persons who were the Issuer’s
Chairperson and Secretary at the time of the execution thereof shall be valid and sufficient for
all purposes notwithstanding that such persons or either of them have ceased to hold such offices
prior to the authentication and delivery of the Bonds or did not hold such offices at the date of
the Bonds. For this purpose a Bond executed by facsimile signature shall be deemed to have been
executed on the date of the printing thereof.

     Section 2.09. Authentication. No Bond shall be entitled to any benefit hereunder or
be valid for any purpose unless there appears on such Bond a certificate of authentication
substantially in the form set forth in Exhibit A attached hereto, executed on behalf of the Trustee
with the manual signature of an authorized signatory of the Trustee. Such certificate of
authentication executed as aforesaid on a Bond shall be conclusive evidence that such Bond has been
authenticated and delivered hereunder.

     Section 2.10. Provision for Registration, Transfer and Exchange of Bonds. The Trustee
shall cause a Bond Register to be kept at the Trustee’s Principal Office for the purpose of
providing for the registration and transfer of Bonds in accordance with the provisions of this
section and such reasonable additional regulations as the Trustee may prescribe. Subject to such
regulations, any Bondowner may cause its address on the Bond Register to be changed by giving
written notice to the Trustee. At reasonable times and under reasonable regulations established by
Trustee, the Bond Register may be inspected and copied by the Company, the Issuer or by Bondowners
(or a designated representative thereof) of 10% or more in aggregate principal amount of Bonds then
Outstanding, the authority of such designated representative to be evidenced to the satisfaction of
Trustee.

     Each Bond shall be fully negotiable. Any Bond may be transferred but only by a written
assignment duly executed by the Bondowner or by such Bondowner’s duly authorized legal
representative. Upon presentation and surrender of the Bond together with said executed form of
assignment at the Trustee’s Principal Office, the Trustee shall register the transfer in the Bond
Register; provided, however, that the Trustee shall have no obligation to register the transfer
unless the executed assignment shall be satisfactory to it in form and substance. Upon
registration of the transfer of a Bond, the Trustee shall cancel the surrendered Bond and the
Issuer shall issue, and the Trustee shall authenticate, one or more new Bonds of authorized
denominations of the same maturity and interest rate and in the same aggregate outstanding
principal amount as the surrendered Bond.

22

 

     The Bondowner requesting any registration of transfer or exchange of Bonds shall pay with
respect thereto any resulting tax or Government charge. All such payments shall be conditions
precedent to the exercise of the Bondowner’s rights of registration of transfer or exchange. The
Trustee shall not be required to register the transfer or to exchange any particular Bond after
such Bond has been selected for redemption. All registrations of transfer and exchanges of Bonds
shall be accomplished in such manner that no increase or decrease in interest payable on the Bonds
results therefrom.

     Section 2.11. Book-Entry System of Bonds. (a) Each maturity of Bonds will be issued
as a single Bond in the name of The Depository Trust Company, New York, New York (the “Securities
Depository”), or its nominee, which will act as depository for the Bonds. During the term of the
Bonds, ownership and subsequent transfers of ownership will be reflected by book entry on the
records of the Securities Depository and those financial institutions for whom the Securities
Depository effects book-entry transfers (collectively, the “Participants”). No person for whom a
Participant has an interest in Bonds (a “Beneficial Owner”) shall receive bond certificates
representing their respective interest in the Bonds except in the event that the Securities
Depository or Issuer shall determine, at its option, to terminate the book-entry system described
in this section. Payment of principal of, and interest on, the Bonds will be made by the Trustee
to the Securities Depository, which will in turn remit such payment of principal and interest to
its Participants, which will in turn remit such principal and interest to the Beneficial Owners of
the Bonds until and unless the Securities Depository or Issuer elect to terminate the book-entry
system, whereupon the Issuer shall deliver bond certificates to the Beneficial Owners of the Bonds
or their nominees. Bond certificates issued under this Section may not be transferred or exchanged
except as provided in this Section.

     (b) Upon the reduction of the principal amount of any maturity of Bonds, the registered
Bondowner may make a notation of such redemption on the panel of the Bond, stating the amount so
redeemed, or may return the Bond to the Trustee for exchange for a new Bond, authenticated by the
Trustee in a proper principal amount. Such notation, if made by the Bondowner, may be made for
reference only, and may not be relied upon by any other person as being in any way determinative of
the principal amount of such Bond Outstanding, unless the Trustee has initialed the notation on the
panel.

     (c) Immediately upon delivery of the Bonds to the Original Purchaser thereof on the delivery
date, such Original Purchaser shall deposit the bond certificates representing all of the Bonds
with the Securities Depository. The Securities Depository, or its nominee, will be the sole
Bondowner of the Bonds, and no investor or other party purchasing, selling or otherwise
transferring ownership of any Bonds will receive, hold or deliver any bond certificates as long as
the Securities Depository holds the Bonds immobilized from circulation.

     (d) The Bonds may not be transferred or exchanged except:

     (i) To any successor of the Securities Depository (or its nominee) or any substitute
depository (“Substitute Depository”) designated pursuant to clause (ii) below, provided that
any successor of the Securities Depository or any Substitute Depository must be a qualified
and registered “clearing agency” as provided in Section 17A of the Securities Exchange Act
of 1934, as amended;

23

 

     (ii) To a Substitute Depository designated by or acceptable to the Issuer upon (A) the
determination by the Securities Depository that the Bonds shall no longer be eligible for
depository services, or (B) a determination by the Issuer that the Securities Depository is
no longer able to carry out its functions, provided that any such Substitute Depository must
be qualified to act as such, as provided in clause (i) above; or

     (iii) To those persons to whom transfer is requested in written transfer instructions
in the event that:

     (A) The Securities Depository shall resign or discontinue its services for the
Bonds, only if the Issuer is unable to locate a qualified successor within two
months following the resignation or determination of noneligibility, or

     (B) Upon a determination by the Issuer that the continuation of the book-entry
system described herein, which precludes the issuance of bond certificates to any
Bondowner other than the Securities Depository (or its nominee), is no longer in the
best interest of the Beneficial Owners of the Bonds.

     (e) The Depository Trust Company, New York, New York, is hereby appointed the Securities
Depository for the Bonds.

     Section 2.12. Persons Treated as Bondowners. The Issuer and the Trustee may treat the
person in whose name any Bond is registered as the absolute owner of such Bond for the purpose of
receiving payment of the principal of, premium, if any, and interest thereon and for all other
purposes whatsoever, whether or not such Bond is overdue and irrespective of any actual, implied or
imputed notice to the contrary.

     Section 2.13. Manner of Payment of Bonds. All payments made by the Company hereunder
shall be made to the Trustee. The interest on any Bond and the principal and premium, if any,
which are payable and are punctually paid or duly provided for on any Payment Date shall be paid as
provided in Section 2.01. Any interest on any Bond which is payable, but is not punctually paid or
duly provided for, may be paid in any lawful manner, at the discretion of the Trustee. The
principal of, premium, if any, and interest on all Bonds shall be paid in lawful money of the
United States of America.

     In any case where the date of maturity of interest on or principal of the Bonds or the date
fixed for redemption of any Bonds shall be, in the city in which the Trustee’s Principal Office is
located, a Saturday, Sunday or a legal holiday, the payment of principal, premium, if any, and
interest need not be made on such date in such city but may be made on the next succeeding Business
Day.

     Interest on any Bond which is payable, and is punctually paid or duly provided for, on any
Redemption Date that is not a regularly scheduled Payment Date, shall be paid as provided in
Section 2.02, payable to the order of the person in whose name the Bond is registered at the close
of business on the day next preceding such Redemption Date.

     Section 2.14. Mutilated, Lost, Stolen or Destroyed Bonds. In the event any Bond is
mutilated, lost, stolen or destroyed, the Issuer may execute and the Trustee may authenticate a new

24

 

Bond of like date, maturity and denomination as the Bond mutilated, lost, stolen or destroyed. In
the case of any lost, stolen or destroyed Bond, there shall first be furnished to the Issuer and
the Trustee evidence of such loss, theft or destruction satisfactory to the Issuer and the Trustee,
together with indemnity satisfactory to them. In the event any such Bond shall have matured, the
Trustee instead of issuing a substitute Bond may pay the same without surrender thereof. The
Issuer and the Trustee may charge the Bondowner of such Bond with their reasonable fees and
expenses in this connection.

     Section 2.15. Disposition of Bonds Upon Payment; Safekeeping of Bonds Surrendered for
Exchange. All Bonds fully paid, fully redeemed or purchased by the Trustee for cancellation
under the provisions hereof shall be cancelled when such final payment, redemption or purchase is
made, and such cancelled Bonds shall be delivered to the Trustee. All cancelled Bonds shall be
destroyed by the Trustee by cremation, shredding or other suitable
means, and the Trustee shall execute a certificate of destruction in duplicate describing the Bonds
so destroyed and one executed certificate shall be filed with the Issuer and the other executed
certificate shall be retained by the Trustee.

     Section 2.16. Nonpresentment of Bonds. In the event any Bond shall not be presented
for payment when the principal thereof becomes due, either at stated maturity or at the date fixed
for redemption thereof, if funds sufficient to pay such Bond shall be held by the Trustee for the
benefit of the Bondowner of such Bond, all liability of the Issuer to the Bondowner of such Bond
for the payment of such Bond shall forthwith cease, terminate and be completely discharged, and
thereupon it shall be the duty of the Trustee to hold such cash in a segregated trust account
without liability for interest thereon, for the benefit of the Bondowner of such Bond who shall
thereafter be restricted exclusively to such account for any claim of whatever nature on such
person’s part hereunder on or with respect to said Bond. Such cash in such segregated trust
account shall thereafter no longer be considered Pledged Revenues and any such Bond shall no longer
be deemed outstanding hereunder.

     After any such cash has been held in such segregated trust account for four years, the Trustee
shall certify the amount thereof and the identifying numbers of the particular Bonds whose
Bondowners have a claim there against (which Bondowners shall also be identified, if known) and
deliver such certificate and such cash to the Company. Thereafter such Bondowners shall have an
unsecured claim against the Company in respect of payment of such unpresented Bonds, and shall have
no further claim whatever against the Issuer or the Trustee in respect thereof.

     Section 2.17. Delivery of Bonds. Upon the execution and delivery of this Loan and
Trust Agreement, the Issuer shall issue and execute and deliver the Bonds to the Trustee, and the
Trustee shall authenticate such Bonds and deliver them to the purchaser(s) as may be directed by
the Issuer.

     Prior to the delivery of the Bonds by the Trustee there shall be filed with the Trustee:

     (a) A certified copy of the resolution(s) of the Issuer authorizing the issuance of the Bonds
and the execution and delivery of this Loan and Trust Agreement;

     (b) Original executed counterparts of this Loan and Trust Agreement, Note and Security
Documents;

25

 

     (c) A request and authorization to the Trustee, executed on behalf of the Issuer by its
Chairperson or Secretary, to deliver the Bonds to the purchaser(s) therein identified, in the form
and amount requested upon payment to the Trustee, for the account of the Issuer, of a specified sum
plus accrued interest on the Bonds to date of delivery thereof;

	 	(d)	 	Certification that the Company has contributed owner’s equity in the amount of
$246,000 to pay for costs of issuance, and that any excess shall be deposited with the
Trustee for deposit first into the Capitalized Interest Account, secondly into the Debt
Service Reserve Fund, and lastly into the Project Costs Account; and
	 
	 	(e)	 	An opinion from Bond Counsel to the effect that interest on the Bonds shall not
be included in gross income for federal or state income tax purposes.

     Section 2.18 Additional Bonds. The Company is not restricted in its ability to incur
additional indebtedness or to secure such indebtedness by liens or security interests in any of its
property, including the property subject to the liens and security interests of the Deed of Trust
securing the Bonds. Pursuant to the Subordination Agreement, additional indebtedness provided by
the Senior Lender may be secured on a senior basis to the Bonds. Up to $20,000,000 of additional
debt may be secured on a parity basis in the property securing the Bonds provided that (i) there
exists no default under this Loan and Trust Agreement, the Bonds or the Senior Credit Facility,
(ii) such additional indebtedness is secured by a debt service reserve fund funded at the time of
issuance in an amount equal to one year’s interest payable on such additional indebtedness; (iii)
the proceeds of such additional indebtedness are used solely to refinance solid waste disposal
equipment in the Facility originally financed from proceeds of the Senior Credit Facility, to fund
the debt service reserve fund and/or to pay costs of issuance of such additional debt, and (iv) the
Debt Service Coverage Ratio, as defined under Article IX hereunder, for the Bonds and the proposed
additional indebtedness is at least 1.5 times for each of the most recent two fiscal years based
upon the audited financial statements of the Company for such years or for each of the five full
fiscal years following the issuance of each additional indebtedness based upon the report of a
nationally recognized consultant delivered to the Trustee forecasting debt service coverage for
such years based upon assumptions such consultant deems reasonable.

     Section 2.19. Parity. This Loan and Trust Agreement is for the equal and ratable
benefit and security of all Bonds issued and to be issued hereunder. All Bonds shall be of equal
rank, and no Bondowner shall be accorded a preference or priority over any other Bondowner except
as expressly authorized or provided herein.

     Section 2.20. Discharge. If the Issuer shall pay or cause to be paid from the Pledged
Revenues the principal, premium, if any, and interest due or to become due on the Bonds or a Series
of Bonds at the times and in the manner stipulated therein, and if the Issuer shall not then be in
default in any of the covenants and promises in the Bonds and in this Loan and Trust Agreement
expressed as to be kept, performed and observed by it or on its part, and shall pay or cause to be
paid (by virtue of the payment of funds to the Trustee or the deposit with or transfer to the
Trustee of Government Obligations) to the Trustee all sums of money due or to become due according
to the provisions hereof, then these presents and the estate and rights hereby granted shall cease,
terminate and be void, whereupon the Trustee shall cancel and discharge the Lien of this Loan and
Trust Agreement (with respect to all Outstanding Bonds) and execute and deliver to the Issuer such
instruments in writing as shall be requisite to cancel and discharge the Lien hereof, and reconvey,

26

 

release, assign and deliver unto the Issuer any and all the estate, right, title and interest in
and to any and all property conveyed, assigned or pledged to the Trustee or otherwise subject to
the Lien of this Loan and Trust Agreement, except moneys or securities held by the Trustee in
separate segregated trust accounts pursuant to this Loan and Trust Agreement for the payment of the
principal of, premium, if any, and interest on unpresented Bonds.

     Notwithstanding the foregoing, no deposit under the immediately preceding paragraph shall be
deemed a payment of such Bonds as aforesaid until:

     (a) The deposit shall have been made under the terms of an escrow trust agreement in form and
substance satisfactory to the Trustee consistent herewith;

     (b) In the case of an escrow trust deposit with respect to Bonds subject to redemption prior
to maturity at the option of the Company, the Company shall have delivered an irrevocable Company’s
Certificate designating when such Bonds are to be paid or redeemed under terms of such escrow trust
agreement;

     (c) In case of Bonds which are to be redeemed prior to maturity from such escrow trust
deposit, a redemption notice meeting the requirements of Section 2.04 and stating that such Bonds
are being redeemed from a deposit made pursuant to this Article shall either (i) have been given,
or (ii) shall have been provided for by delivery to the Trustee of irrevocable instructions for the
giving of such notice;

     (d) The Trustee shall have been furnished with an opinion of Bond Counsel to the effect that
the payment of the Bonds in accordance with said escrow trust agreement will not adversely affect
the excludability from gross income of the Bondowners for federal income tax purposes and will not
cause the Bonds to be classified as “arbitrage bonds” under Section 148 of the Code;

     (e) The Trustee shall have covenanted to give notice of such deposit to the Bondowner of each
Bond outstanding at the address shown on the Bond Register; and

     (f) With respect to the payment to transfer or deposit the Trustee of Government Obligations,
if the Trustee so requests, the Trustee shall have been furnished with a verification report from
an Independent Accountant, or such other service acceptable to the Trustee, providing that such
deposit shall mature or be subject to redemption at the option of the holder thereof, in amounts
necessary to pay such Bonds or Series of Bonds when due.

     All moneys set aside and held in trust pursuant to the provisions of this Article for the
payment of Bonds (including interest and premium thereon, if any) shall be applied to and used
solely for the payment of the particular Bonds (including interest and premium thereon, if any)
with respect to which such moneys have been so set aside in trust.

     If moneys have been deposited or set aside with the Trustee pursuant to this Article for the
payment of Bonds and the interest and premium, if any, thereon and such Bonds and the interest and
premium, if any, thereon shall not have in fact been actually paid in full, no amendment to the
provisions of this Section shall be made without the consent of the Bondowner of each of the Bonds
affected thereby.

ARTICLE III

FUNDS AND ACCOUNTS

     Section 3.01. Application of Proceeds of Bonds. Upon the receipt by the Trustee of
the Bond Proceeds, including the amount received as accrued interest, if any, thereon, and the
required deposit by the Company pursuant to Section 2.17 the Trustee shall apply such proceeds,
excluding the $140,000.00 underwriter’s discount, as follows:

     (a) $246,000.00 shall be deposited into the Issuance Expense Account of the Project Fund from
the required deposit by the Company pursuant to Section 2.17;

     (b) $753,375.00, representing approximately 20 months’ interest on the Bonds, shall be
deposited in the Capitalized Interest Account of the Project Fund;

     (c) $472,500.00, equal to the Debt Service Reserve Fund Requirement will be deposited in the
Debt Service Reserve Fund; and

     (d) the balance of the Bond Proceeds shall be deposited in the Project Costs Account.

     Section 3.02. Creation of Funds and Accounts. (a) The Issuer hereby establishes and
creates the following special trust funds and accounts all relating to the Bonds:

          (i) Project Fund

(A) Issuance Expense Account

(B) Capitalized Interest Account

(C) Project Costs Account

          (ii) Condemnation and Awards Fund

          (iii) Bond Fund

(A) Principal Account

(B) Interest Account

(C) Redemption Account

(D) Sinking Fund Installment Account

          (iv) Debt Service Reserve Fund

          (v) Earnings Fund

(A) Construction Earnings Account

          (vi) Rebate Fund

28

 

     (b) All of the Funds and Accounts created hereunder shall be held by the Trustee. All moneys
and investments deposited with the Trustee shall be held in trust and applied only in accordance
with this Loan and Trust Agreement and shall be Trust Funds for the purposes of this Loan and Trust
Agreement.

     Section 3.03. Project Fund. (a) There shall be deposited to the respective accounts
of the Project Fund, separate from any other fund or account and designated relating to the Bonds,
any and all amounts required to be deposited therein pursuant to Sections 3.01 and 3.08. The
amounts in the Project Fund shall be subject to a security interest in favor of the Trustee until
disbursed as provided herein. The Trustee shall apply the amounts on deposit in the Project Fund
to the payment, or reimbursement to the extent the same have been paid by or on behalf of the
Company or the Issuer, of Project Costs to the extent requisitioned under this Section and Section
4.02.

     (b) Issuance Expense Account. The Trustee shall deposit amounts set forth in Section
3.01 in the Issuance Expense Account separate from any other fund or account and designated
relating to the Bonds, and apply such amounts to pay Bond issuance costs. Such disbursements shall
be made upon receipt of a Company’s Requisition relating to the same. If there shall be any
balance in the Issuance Expense Account remaining after all Bond issuance costs have been paid, the
Trustee shall transfer such remaining balance to the Project Costs Account relating to such Series
of Bonds.

     (c) Capitalized Interest. The Trustee shall deposit the amounts in the Capitalized
Interest Account separate from any other fund or account and apply such amount to the payment of
the interest on the Bonds as the same shall become due until the earlier of the Completion Date or
the exhaustion of amounts in such Account (the “Capitalized Interest Period”). On the Business Day
immediately preceding each Interest Payment Date during the Capitalized Interest Period, the
Trustee shall transfer from the Capitalized Interest Account to the Interest Account an amount
sufficient to pay the interest on the Bonds becoming due on the immediately succeeding Interest
Payment Date. Upon the Completion Date, unless the Trustee has received an opinion from Bond
Counsel that the continued use of the capitalized interest to pay interest on the Bonds will not
cause the Bonds to lose their tax-exempt status, the Trustee shall transfer any balance remaining
in the Capitalized Interest Account to the Project Costs Account to pay any remaining Project
Costs.

     In addition, if, on the Business Day immediately preceding any Interest Payment Date occurring
prior to the Completion Date, the amount on deposit in the Capitalized Interest Account is not
sufficient to pay the interest on the Bonds becoming due on the next succeeding Interest Payment
Date, the Trustee shall transfer from the Project Costs Account to the Interest Account an amount
which, when added to the amount on deposit in the Interest Account (after giving effect to any
transfer to such Fund from the Capitalized Interest Account as provided above), is sufficient to
pay the interest on the Bonds becoming due on such Interest Payment Date.

     (d) Project Costs Account. The Trustee shall deposit the amounts set forth in
Sections 3.01, 3.03(b) and 3.08 to the Project Costs Account and is hereby authorized to disburse
from the Project Costs Account the amount required for the payment of Project Costs and is directed
to issue its checks or make wire transfer of payments for each disbursement from the Project Costs
Account,
upon receipt by the Trustee of a Company’s Requisition substantially in the form of Exhibit B
attached hereto, subject to the provisions of Section 4.02.

29

 

     On or after the Completion Date, the balance in the Project Costs Account in excess of the
amount, if any, stated in such certificate for the payment of any remaining part of the costs of
the Project, shall, after making any transfer to the Rebate Fund as directed pursuant to the Tax
Regulatory Agreement and Section 3.09, be deposited by the Trustee in the Redemption Account. Upon
payment of all the costs and expenses incident to the completion of the Project, any balance of
such remaining amount in the Project Costs Account, together with any amount on deposit in the
Earnings Fund derived from transfers made thereto from the Project Fund, shall, after making any
such transfer to the Rebate Fund, and after depositing in the Debt Service Reserve Fund an amount
equal to any deficiency therein, be deposited in the Redemption Account to be applied to the
redemption of Bonds at the earliest practicable date as set forth in 2.02(b)(ii) hereof, or applied
to such other purpose as the Company shall direct the Trustee in writing, provided that in any case
the Company shall provide the Trustee with an opinion of Bond Counsel to the effect that the
application of such excess proceeds to such alternate purpose will not cause the interest on the
Bonds to be includable in gross income for federal income tax purposes. The Trustee shall promptly
notify the Company of any amounts so deposited in the Redemption Account pursuant to this Section.

     (e) The Trustee shall keep and maintain adequate records pertaining to each account of the
Project Fund and all disbursements therefrom and shall furnish copies of same to the Issuer or the
Company upon reasonable notice and written request.

     (f) The Trustee shall on written request furnish to the Issuer and the Company within a
reasonable time period a written statement of disbursements from each account of the Project Fund,
enumerating, among other things, item, cost, amount disbursed, date of disbursement and the person
to whom payment was made, together with copies of all bills, invoices or other evidences submitted
to the Trustee for such disbursement.

     (g) In the event the Company shall be required to or shall elect to cause the Bonds to be
redeemed in whole pursuant to this Loan and Trust Agreement, the balance in the Project Fund and in
the Earnings Fund (in excess of any amount the Trustee is directed to transfer to the Rebate Fund
pursuant to the Tax Regulatory Agreement and Section 3.09) shall be deposited in the Redemption
Account relating to such Series of Bonds. In the event the unpaid principal amount of the Bonds
shall be accelerated upon the occurrence of an Event of Default hereunder, the balance in the
Project Fund and in the Earnings Fund (in excess of any amount the Trustee is directed to transfer
to the Rebate Fund pursuant to the Tax Regulatory Agreement and Section 3.09) shall be deposited in
the Bond Fund.

     (h) Except as provided in Section 3.08, all earnings on amounts held in the Project Fund shall
be transferred by the Trustee and deposited as follows: (i) earnings derived from amounts on
deposit in the Project Costs Account shall be deposited in the Construction Earnings Account. Any
transfers by the Trustee of amounts to the Rebate Fund shall first be drawn by the Trustee from the
Earnings Fund in accordance with Section 3.08(c), prior to drawing any amounts from the Project
Fund.

     Section 3.04. Condemnation and Awards Fund. (a) Subject to the Senior Credit Facility
to the extent the Trustee has the right to the Net Proceeds of title insurance claims, casualty
insurance claims and eminent domain awards in accordance with and to the extent provided herein or
the Deed of Trust, the Trustee shall deposit into the Condemnation and Awards Fund relating to such

30

 

Series of Bonds, when and as received such Net Proceeds; provided, however, that if the Net
Proceeds shall be less than $100,000, such Net Proceeds shall be paid over to the Company. The
amounts in the Condemnation and Awards Fund shall be subject to a security interest in favor of the
Trustee until disbursed as provided herein.

     (b) In the event the Bonds shall be subject to redemption in whole (either pursuant to Section
2.02(d) or otherwise) pursuant to the terms thereof or this Loan and Trust Agreement, the Trustee
shall, after making any transfer to the Rebate Fund as directed pursuant to the Tax Regulatory
Agreement and Section 3.09, transfer the amounts deposited in the Condemnation and Awards Fund to
the Redemption Account.

     If, on the other hand, the Bonds shall not be subject to redemption in whole (whether pursuant
to Section 2.02(d) or otherwise), the Trustee shall apply the amounts on deposit in the
Condemnation and Awards Fund, after making any transfer to the Rebate Fund as directed pursuant to
the Tax Regulatory Agreement and Section 3.09, to such rebuilding, replacement, repair and
restoration.

     (c) If an Event of Default shall exist at the time of the receipt by the Trustee of the Net
Proceeds in the Condemnation and Awards Fund, the Trustee shall promptly request the written
direction of the Owners of a majority in aggregate principal amount of the Bonds outstanding, and,
if such Event of Default shall not have been cured or waived, shall thereupon apply such Net
Proceeds, after making any transfer to the Rebate Fund as directed pursuant to the Tax Regulatory
Agreement and Section 3.09, to the rebuilding, replacement, repair and restoration of the Facility,
or for deposit in the Redemption Account as directed by such percentage of Bondholders (or if no
such direction shall be received within ninety (90) days after request therefor by the Trustee
shall have been made, for deposit in the Redemption Account) provided, that no such directions
shall allow for a distribution other than ratably among the Bondowners.

     (d) The Trustee is hereby authorized to apply the amounts in the Condemnation and Awards Fund
to the payment (or reimbursement to the extent the same have been paid by or on behalf of the
Company or the Issuer) of the costs required for the rebuilding, replacement, repair and
restoration of the Facility in substantially the same manner as provided for disbursements from the
Project Costs Account. The Trustee shall keep and maintain adequate records pertaining to the
Condemnation and Awards Fund and all disbursements therefrom and shall furnish copies of same to
the Issuer and the Company upon reasonable written request therefor.

     (e) The date of completion of the restoration of the Facility shall be evidenced to the Issuer
and the Trustee by a Company’s Certificate stating (i) the date of such completion, (ii) that all
labor, services, machinery, equipment, materials and supplies used therefor and all costs and
expenses in connection therewith have been paid for, (iii) that the Facility has been restored to
substantially its condition immediately prior to the loss event, or to a condition of at least
equivalent value, operating efficiency and function, (iv) that the Issuer has good and valid title
to all property
constituting part of the restored Facility, all property of the Facility is subject to the Lien and
security interest of the Deed of Trust, (v) the Rebate Amount applicable with respect to the Net
Proceeds and the earnings thereon (with a statement as to the determination of the Rebate Amount
and a direction to the Trustee of any required transfer to the Rebate Fund), and (vi) that the
restored Facility is ready for occupancy, use and operation for its intended purposes.
Notwithstanding the foregoing, such certificate shall state (x) that it is given without prejudice
to any rights of the

31

 

Company against third parties which exist at the date of such certificate or
which may subsequently come into being, (y) that it is given only for the purposes of this Section,
and (z) that no Person other than the Issuer or the Trustee may benefit therefrom. If the Net
Proceeds received from the loss event shall be equal to or greater than $500,000, such certificate
shall be accompanied by those same documents as are required to evidence the Completion Date of the
Project.

     (f) All earnings on amounts on deposit in the Condemnation and Awards Fund shall be
transferred by the Trustee and deposited in the Earnings Fund. Any transfers by the Trustee of
amounts to the Rebate Fund shall first be drawn by the Trustee from the Earnings Fund in accordance
with Section 3.08(c), prior to drawing any amounts from the Condemnation and Awards Fund.

     (g) Any surplus remaining in the Condemnation and Awards Fund after the completion of the
rebuilding, replacement, repair and restoration of the Facility shall, after making any transfer to
the Rebate Fund as directed pursuant to the Tax Regulatory Agreement and Section 3.09, and after
depositing in the Debt Service Reserve Fund an amount equal to any deficiency therein, be
transferred by the Trustee to the Redemption Account.

     Section 3.05. Payments into Bond Fund. The Trustee shall promptly deposit the
following receipts into the designated account in the Bond Fund:

     (a) Loan repayments of the Company pursuant to the Note.

     (b) Amounts disbursed from any Account of the Project Fund for the payment of interest on the
Bonds during the period of construction of the Project, which shall be credited to the Interest
Account and applied to the payment of interest on the Series of Bonds relating to such account.

     (c) Excess or remaining amounts in the Project Costs Account pursuant to Section 3.03(d).

     (d) Amounts in the Condemnation and Awards Fund transferred pursuant to Section 3.04.

     (e) Any amounts transferred from the Earnings Fund pursuant to Section 3.08, which shall be
deposited in and credited to the Interest Account.

     (f) Any amounts transferred from the Debt Service Reserve Fund pursuant to Section 3.07, which
shall be deposited in and credited to the Interest Account, the Principal Account, the
Sinking Fund Installment Account or the Redemption Account, as the case may be, relating to such
Series of Bonds, and applied to the payment of amounts due under the Bonds only.

     (g) Any amounts transferred from the Redemption Account pursuant to Section 3.06, which shall
be deposited to the Interest Account, the Principal Account and the Sinking Fund Installment
Account, as the case may be, relating to such Series of Bonds, and in such order of priority, and
applied solely to such purposes.

32

 

     (h) Any amounts transferred from the Redemption Account pursuant to Section 3.06, which shall
be deposited to the Interest Account, and the Principal Account, as the case may be, relating to
such Series of Bonds, and in such order of priority, and applied solely to such purposes.

     (i) All other receipts when and if required by this Loan and Trust Agreement, the Deed of
Trust or by any other Security Document to be paid into the Bond Fund.

     Section 3.06. Application of Bond Fund Moneys. (a) The Trustee shall (i) on each
Interest Payment Date pay or cause to be paid out of the Interest Account, the interest due on the
Bonds, and (ii) further pay out of the Interest Account any amounts required for the payment of
accrued interest upon any purchase or redemption (including any mandatory Sinking Fund Installment
redemption) of the Bonds.

     (b) The Trustee shall on each principal payment date pay out of the Principal Account, the
principal amount, if any, due on the Bonds (other than such as shall be due by mandatory Sinking
Fund Installment redemption), upon the presentation and surrender of the requisite Bonds.

     (c) The Trustee shall pay from the Sinking Fund Installment Account on each Sinking Fund
Installment payment date in immediately available funds the amounts required for the Sinking Fund
Installment due and payable with respect to such Series of Bonds which are to be redeemed from
Sinking Fund Installments on such date (accrued interest on such Bonds being payable from the
Interest Account). The Trustee shall call for redemption Bonds for which Sinking Fund Installments
are applicable in a principal amount equal to the Sinking Fund Installment then due with respect to
such Bonds. Such call for redemption shall be made even though at the time of mailing of the
notice of such redemption sufficient moneys therefor shall not have been deposited in the Bond Fund
relating to such Bonds. Any amounts deposited in the Sinking Fund Installment Account and not
applied to the payment of Sinking Fund Installments due on the Bonds shall not be invested at a
Yield greater than the Yield on the Bonds.

     (d) Amounts in the Redemption Account shall be applied, at the written direction of the
Company, as promptly as practicable, to the purchase of such Bonds at prices not exceeding the
Redemption Price thereof applicable on the earliest date upon which such Bonds are next subject to
redemption, plus accrued interest to the date of redemption. Any amount in the Redemption Account
not so applied to the purchase of such Bonds by forty-five (45) days prior to the next date on
which the Bonds are so redeemable shall be applied to the redemption of Bonds on such redemption
date. Any amounts deposited in the Redemption Account and not applied within twelve (12) months of
their date of deposit to the purchase or redemption of Bonds shall be transferred to the Interest
Account. Upon the purchase of any Bonds out of advance loan payments as provided in
this paragraph, or upon the redemption of any Bonds, an amount equal to the principal of such Bonds
so purchased or redeemed shall be credited against the Sinking Fund Installments for such Bonds in
such order as an Authorized Officer of the Company shall direct the Trustee in writing (or, in the
absence of any such written direction, in inverse order of the due dates of such Sinking Fund
Installments) until the full principal amount of such Bonds so purchased or redeemed shall have
been so credited. The portion of any such Sinking Fund Installment remaining after the deduction
of such amounts so credited shall constitute and be deemed to be the amount of such Sinking Fund
Installment for the purposes of any calculation thereof under this Loan and Trust Agreement.

33

 

     (e) In connection with purchases of Bonds out of the Bond Fund as provided in this Section,
the Company shall arrange and the Trustee shall execute such purchases (through brokers or
otherwise, and with or without receiving tenders) at the written direction of the Company;
provided, however, that the Trustee may not effect such purchases through a broker unless the
Company shall have previously approved in writing the use of such broker and the amount of such
broker’s fees. The payment of the purchase price shall be made out of the moneys deposited in the
Redemption Account and the payment of accrued interest shall be made out of moneys deposited in the
Interest Account.

     (f) The Issuer shall receive a credit in respect of Sinking Fund Installments for any Bonds
which are subject to mandatory Sinking Fund Installment redemption and which are delivered by the
Issuer or the Company to the Trustee on or before the 45th day next preceding any Sinking Fund
Installment payment date and for any Bonds which prior to said date have been purchased or redeemed
(otherwise than through the operation of the Sinking Fund Installment Account) and cancelled by the
Trustee and not theretofore applied as a credit against any Sinking Fund Installment. Each Bond so
delivered, cancelled or previously purchased or redeemed shall be credited by the Trustee at 100%
of the principal amount thereof against the obligation of the Issuer to pay such Sinking Fund
Installments in such order of the due dates of such Sinking Fund Installments of applicable Bonds
and maturity as an Authorized Officer of the Company shall direct the Trustee in writing (or, in
the absence of such written direction, in the inverse order of the due dates of such Sinking Fund
Installments), and the principal amount of Bonds to be redeemed by application of Sinking Fund
Installment payments shall be accordingly reduced.

     (g) The Company shall on or before the 45th day next preceding each Sinking Fund Installment
payment date furnish the Trustee with the Company’s Certificate indicating whether or not and to
what extent the provisions of this Section are to be availed of with respect to such Sinking Fund
Installment payment, stating, in the case of the credit provided for, that such credit has not
theretofore been applied against any Sinking Fund Installment and confirming that immediately
available cash funds for the balance of the next succeeding prescribed Sinking Fund Installment
payment will be paid on or prior to the next succeeding Sinking Fund Installment payment date.

     (h) Moneys in the Redemption Account for a Series of Bonds which are not set aside or
deposited for the redemption or purchase of Bonds shall be transferred by the Trustee to the
Interest Account, to the Principal Account or to the Sinking Fund Installment Account relating to
such Series of Bonds.

     (i) In the event that a deficiency shall exist in any Account of the Bond Fund on any Interest
Payment Date after giving effect to any transfers made pursuant to Section 3.05, the Trustee shall
make demand on the Company for such deficiency.

     Section 3.07. Debt Service Reserve Fund.

     (a) If on any Interest Payment Date or redemption date for the Bonds the amount in the
Interest Account (after taking into account amounts available to be transferred to the Interest
Account from the Project Fund) shall be less than the amount of interest then due and payable on
the Bonds, or if on any principal payment date for the Bonds the amount in the Principal Account
shall be less than the amount of principal of the Bonds then due and payable, or if on any Sinking
Fund Installment payment date for the Bonds the amount in the Sinking Fund Installment Account

34

 

shall be less than the amount of the Sinking Fund Installment then due and payable on the Bonds,
in each case, after giving effect to all payments received by the Trustee in immediately available
funds by 10:00 a.m. (Lincoln, Nebraska time) on such date, the Trustee forthwith shall transfer
moneys from the Debt Service Reserve Fund, first to such Interest Account, second to such Principal
Account, and third to such Sinking Fund Installment Account, all to the extent necessary to make
good any such deficiency.

     (b) In lieu of cash or securities, the Debt Service Reserve Fund may be established, funded or
refunded (at any time), in whole or in part, with a letter of credit or surety bond issued to the
Trustee by a credit facility provider which is rated in one of the three (3) highest Rating
Categories, which permits the Trustee to receive up to full payment therefrom by no later than 3:00
p.m. (Lincoln, Nebraska time) if the Trustee makes demand for payment by no later than 11:00 a.m.
(Lincoln, Nebraska time) on the same Business Day, and the terms and conditions of which do not
impose financial obligations on, or create significant adverse drawing difficulties for, the
Trustee. In the event that a Debt Service Reserve Fund Facility is delivered to the Trustee, the
Trustee shall immediately draw upon such Debt Service Reserve Fund Facility if and to the extent
that the provisions of this Loan and Trust Agreement require a transfer of funds from the Debt
Service Reserve Fund. If the Debt Service Reserve Fund Facility is to expire by its terms, and the
Debt Service Reserve Fund Requirement with respect to the Bonds is not otherwise satisfied, the
Trustee shall immediately draw upon the Debt Service Reserve Fund Facility in an amount equal to
the full amount thereof. If in the event that during the term of the Debt Service Reserve Fund
Facility, the provider thereof ceases to be rated in one of the three (3) highest Rating
Categories, the Company shall, no later than sixty (60) days following the reduction in the rating
of the provider of the Debt Service Reserve Fund Facility, regardless of the date the Company or
the Trustee receives notice or actual knowledge of such reduction, either (i) cause there to be
deposited with the Trustee a Debt Service Reserve Fund Facility, the provider of which is rated in
one of the three (3) highest Rating Categories and otherwise meeting the requirements for a Debt
Service Reserve Fund Facility set forth above, or (ii) cause there to be deposited with the Trustee
cash in an amount equal to the Debt Service Reserve Fund Requirement.

     (c) On June 15 and December 15 of each year and upon any payment of the principal or Sinking
Fund Installments of the Bonds, the Trustee shall determine whether the amount of on deposit in the
Debt Service Reserve Fund exceeds the Debt Service Reserve Fund Requirement with respect to the
Bonds. If an excess exists, the Trustee shall notify the Issuer and the Company, and shall take
such other actions, as may be necessary in order to effect a reduction in the amount of the Debt
Service Reserve Fund Facility to an amount equal to the then-applicable Debt Service Reserve Fund
Requirement.

     (d) In the case of the Debt Service Reserve Fund, a “surplus” means the amount by which the
amount on deposit therein is in excess of the Debt Service Reserve Fund Requirement with respect to
the Bonds. On June 15 and December 15 of each year and upon any withdrawal from the Debt Service
Reserve Fund, the Trustee shall determine the amount on deposit in the Debt Service Reserve Fund.
If on any such date a deficiency exists, the Trustee shall notify the Issuer and the Company of
such deficiency and that such deficiency must be replenished by the Company as provided for herein.
If a surplus exists, the Trustee shall notify the Issuer and the Company thereof and, subject to
the requirements of the Tax Regulatory Agreement, shall upon written instructions of the Company
transfer an amount equal to such surplus to the Project Costs Account until the Completion Date and
thereafter shall transfer such amount to the Interest Account.

35

 

     Section 3.08. Payments into Earnings Fund: Application of Earnings Fund. (a) The
amounts in the Earnings Fund relating to a Series of Bonds shall be subject to a security interest
in favor of the Trustee for the benefit of the Bondholders only to the extent of amounts therein in
excess of the amounts necessary to satisfy federal rebate requirements.

     (b) All investment income or earnings on amounts held in the Project Fund, the Condemnation
and Awards Fund, the Debt Service Reserve Fund or any other special fund other than the Rebate Fund
or the Bond Fund shall be deposited upon receipt by the Trustee into the Earnings Fund of such
Series of Bonds; provided, however, that there shall not be required to be deposited in the
Earnings Fund any amounts received from the investment of moneys in obligations described in
Section 103(a) of the Code.

     (c) On the first Business Day following each Computation Period (as defined in the Tax
Regulatory Agreement) and the receipt by the Trustee of a Company’s Certificate delivered to the
Trustee pursuant to the Tax Regulatory Agreement, the Trustee shall withdraw from the Earnings Fund
of such Series of Bonds that amount, if any, as is directed by such certificate to be deposited in
the Rebate Fund of such Series of Bonds and deposit, to the extent available, such amount in the
Rebate Fund, such that the amount held in the Rebate Fund after such deposit is equal to the Rebate
Amount calculated as of the last day of the Computation Period; provided, however, in withdrawing
amounts from the Earnings Fund, the Trustee shall withdraw amounts in every Account therein in the
proportion that amounts in each such Account shall bear to the aggregate sum held in the Earnings
Fund relating to a Series of Bonds. In the event of any deficiency, the balance required shall be
provided by the Company pursuant to the Tax Regulatory Agreement. Computations of the amounts on
deposit in each Fund and Account and of the Rebate Amount shall be furnished to the Trustee by the
Company in accordance with the Tax Regulatory Agreement.

     The foregoing notwithstanding, the Company shall either (1) demonstrate to the satisfaction of
the Trustee that the applicable requirements of a spending exception to rebate has been satisfied
as of the relevant semi-annual period as set forth in the Tax Regulatory Agreement, (2) perform and
submit to the Trustee a calculation intended to determine its approximate rebate liability in
respect of the Bond Proceeds relating to a Series of Bonds, which calculation shall be undertaken
at least annually, or (3) provide information to the Trustee demonstrating that the Bond Proceeds
have been
invested in obligations the interest on which is not included in gross income for federal income
tax purposes under Section 103 of the Code.

     Any amounts remaining in the Earnings Fund following a required transfer to the Rebate Fund as
provided in the previous paragraph will be deposited into the related Account of the Project Fund
from which such amount in the Earnings Fund shall have derived (or, in the case of earnings derived
from the Condemnation and Awards Fund or the Debt Service Reserve Fund, such amounts shall be
deposited in the Project Costs Account) until the Completion Date and to the Interest Account
thereafter.

     Section 3.09. Payments into Rebate Fund; Application of Rebate Fund. (a) The Rebate
Fund and the amounts deposited therein shall not be subject to a security interest, pledge,
assignment, lien or charge in favor of the Trustee or any Bondholder or any other Person.

36

 

     (b) The Trustee, on the first Business Day following each Computation Period (as defined in
the Tax Regulatory Agreement) and the receipt of a Company’s Certificate pursuant to the Tax
Regulatory Agreement, shall deposit in the Rebate Fund that amount from the Earnings Fund, to the
extent available, as shall be so specified in such certificate of written direction. If there has
been delivered to the Trustee a certification of the Rebate Amount (as defined in the Tax
Regulatory Agreement) in conjunction with the completion of the Project or the restoration of the
Facility pursuant to Section 3.04, the Trustee shall at the written direction of an Authorized
Officer of the Company deposit in the Rebate Fund such amount so specified in such certification as
required in order that the amount held in the Rebate Fund after such deposit is equal to the Rebate
Amount calculated at the completion of the Project or the restoration of the Facility as aforesaid.
The amount deposited in the Rebate Fund pursuant to the previous sentences shall be withdrawn from
the Earnings Fund; provided, however, in withdrawing amounts from the Earnings Fund, the Trustee
shall withdraw amounts in every Account therein in the proportion that amounts in each such Account
shall bear to the aggregate sum held in the Earnings Fund.

     (c) In the event that the amount on deposit in the Rebate Fund exceeds the Rebate Amount as
determined in accordance with the Tax Regulatory Agreement, the Trustee, upon the receipt of
written instructions from an Authorized Officer of the Company, shall withdraw such excess amount
and deposit it in the related Account of the Project Fund from which such amount so deposited in
the Earnings Fund shall have derived (or, in the case of earnings derived from the Condemnation and
Awards Fund or the Debt Service Reserve Fund, such amounts shall be deposited in the Project Costs
Account) until the completion of the Project, or, after the Completion Date, deposit it in the
Interest Account relating to such Series of Bonds.

     (d) The Trustee, upon the receipt of written instructions from an Authorized Officer of the
Company, shall pay to the United States of America, out of amounts in the Rebate Fund, (i) not
later than 30 days after the end of each five (5) year period after the date of original issuance
of the Bonds, an amount such that, together with prior amounts paid to the United States of
America, the total paid to the United States of America is equal to 90% of the Rebate Amount with
respect to such Series of Bonds calculated as of the end of the most recent Computation Period, and
(ii) not
later than thirty (30) days after the date on which all of such Series of Bonds has been redeemed
or paid in full, 100% of the Rebate Amount as of the end of the final Computation Period.

     (e) The Company agrees to retain an arbitrage rebate consultant to calculate the rebate amount
at least each Computation Period, and annually at its discretion or as may be required for the
preparation of its annual financial statements. In the event that the amounts available in the
Rebate Fund are insufficient to pay the required rebate payment, the Company shall pay all amounts
required to the Trustee for payment to the United States of America.

     Section 3.10. Investment of Funds and Accounts. (a) Amounts in any fund or account
established under this Loan and Trust Agreement may, if and to the extent then permitted by law, be
invested only in Qualified Investments. For the purposes of this Section, investments shall be
considered as maturing on the date on which they are redeemable without penalty at the option of
the holder or the date on which the Trustee may require their repurchase pursuant to a repurchase
agreement qualifying as a Qualified Investment. Any investment herein authorized is subject to the
condition that no portion of the proceeds derived from the sale of the Bonds shall be used,
directly or indirectly, in such manner as to cause any Bond to be an “arbitrage bond” within the
meaning of Section 148 of the Code. In particular, unexpended Bond Proceeds transferred from the
Project

37

 

Fund (or from the Earnings Fund with respect to amounts deposited therein from the Project
Costs Account) to the Redemption Account pursuant to Section 3.03(d) may not be invested at a Yield
(as defined in the Tax Regulatory Agreement) which is greater than the Yield on the Bonds. Such
investments shall be made by the Trustee only at the written request of an Authorized Officer of
the Company; and if such investment is to be in one or more certificates of deposit, then such
written request shall include written assurance to the effect that such investment complies with
the Tax Regulatory Agreement. Any investment hereunder shall be made in accordance with the Tax
Regulatory Agreement, and the Company shall so certify to the Trustee with each such investment
direction as referred to below. Such investments shall mature in such amounts and at such times as
may be necessary to provide funds when needed to make payments from the applicable Fund. Net
income or gain received and collected from such investments shall be credited and losses charged to
(i) the Rebate Fund with respect to the investment of amounts held in the Rebate Fund, (ii) the
Bond Fund with respect to the investment of amounts held in the Bond Fund, and (iii) the Earnings
Fund relating to a Series of Bonds with respect to the investment of amounts held in the Earnings
Fund or any other Fund.

     (b) At the written request of the Company no sooner than ten (10) Business Days prior to each
Payment Date, the Trustee shall notify the Company of the amount of such net investment income or
gain received and collected subsequent to the last Payment Date and the amount then available in
the various Accounts of the Bond Fund.

     (c) Upon the written direction of an Authorized Officer of the Company, the Trustee shall sell
at the best price reasonably obtainable, or present for redemption or exchange, any obligations in
which moneys shall have been invested to the extent necessary to provide cash in the respective
Funds or Accounts, to make any payments required to be made therefrom, or to facilitate the
transfers of moneys or securities between various Funds and Accounts as may be required from time
to time pursuant to the provisions of this Article. The Trustee shall not be liable for losses
incurred as a result of actions taken in good faith in accordance with this Section. As soon as
practicable after any such sale, redemption or exchange, the Trustee shall give notice thereof to
the Issuer and the Company.

     (d) Neither the Trustee nor the Issuer shall be liable for any loss arising from, or any
depreciation in the value of any obligations in which moneys of the Funds and Accounts shall be
invested in accordance with this Loan and Trust Agreement. The investments authorized by this
Section shall at all times be subject to the provisions of applicable law, as amended from time to
time.

     (e) In computing the amount in any Fund or Account, obligations purchased as an investment of
moneys therein shall be valued at fair market value as determined by the Trustee one month prior to
each Interest Payment Date.

     The fair market value of Qualified Investments shall be determined as follows:

     (i) Except as elsewhere specifically stated below, the fair market value of a Qualified
Investment is the price at which a willing buyer would purchase the Qualified Investment
from a willing seller in a bona fide arm’s-length transaction.

38

 

     (ii) The purchase price of a guaranteed investment contract is treated as its fair
market value on the purchase date if:

     (A) The Company makes a bona fide solicitation for a specified guaranteed
investment contract and receives at least three (3) bona fide bids from providers
that have no material financial interest in the issue (e.g., as underwriters or
brokers);

     (B) The Company purchases the highest yielding guaranteed investment contract
for which a qualifying bid is made (determined net of broker’s fees);

     (C) The yield on the guaranteed investment contract (determined net of broker’s
fees) is not less than the yield then available from the provider on reasonably
comparable guaranteed investment contracts, if any, offered to other Persons from a
source of funds other than Gross Proceeds (as defined in the Tax Regulatory
Agreement) of tax-exempt bonds;

     (D) The determination of the terms of the guaranteed investment contract takes
into account as a significant factor the Company’s reasonably expected draw-down
schedule for the amounts to be invested, exclusive of amounts deposited in debt
service funds and reasonably required reserve or replacement funds;

     (E) The terms of the guaranteed investment contract, including collateral
security requirements, are reasonable; and

     (F) The obligor on the guaranteed investment contract certifies the
administrative costs that it is paying (or expects to pay) to third parties in
connection with the guaranteed investment contract;

     (G) If the Issuer uses an agent to conduct the bidding process, the agent does
not bid to provide the investment;

     (H) All bidders have equal opportunity to bid so that no bidder is given the
opportunity to review the other bids before bidding; and

     (I) All bidders are reasonably competitive providers of investments of the type
purchased.

	 	(iii)	 	The fair market value of a certificate of deposit is its
purchase price if it has a fixed rate of interest, a fixed payment schedule,
and a substantial penalty for early withdrawal and the yield on the certificate
of deposit is not less than (1) the yield on reasonably comparable direct
obligations of the United States, and (2) the highest yield published or posted
by the provider to be currently available on reasonably comparable certificates
of deposit offered to the public.

(iv) The fair market value of the Debt Service Reserve Fund Facility shall be the
amount remaining on such Debt Service Reserve Fund Facility to be drawn on.

Notwithstanding any other provision of this Loan and Trust Agreement, if on any Interest Payment
Date or redemption date the amounts held in the Funds established under this Loan and Trust
Agreement (other than the Earnings Fund and the Rebate Fund) are sufficient to pay 100% of the
principal or Redemption Price, as the case may be, of all Outstanding Bonds and the interest
accruing on such Bonds to the next date on which such Bonds are redeemable or payable, as the case
may be, whichever is earlier, the Trustee shall so notify the Issuer and the Company. Upon receipt
of written instructions from the Company directing such redemption, the Trustee shall proceed to
redeem all such Outstanding Bonds in the manner provided for redemption of such Bonds by this Loan
and Trust Agreement.

Trust Agreement and all investments made therewith shall be held by the Trustee in trust for the
benefit of the Bondholders of the Series of Bonds relating to such funds, and while held by the
Trustee constitute part of the Trust Estate of the Series of Bonds relating to such funds, other
than the Rebate Fund and, to the extent amounts on deposit in the Earnings Fund are necessary to
pay federal tax rebate requirements, the Earnings Fund, and be subject to the Lien hereof;
provided, however, that amounts held by the Trustee and obtained pursuant to Article VIII hereof
shall be held for the ratable benefits of all Bondholders.

     Section 3.13. Repayment to the Company from the Funds. After payment in full of the
Bonds and the payment of all fees, charges and expenses of the Issuer, the Trustee, the Bond
Registrar and the Paying Agents and all other amounts required to be paid hereunder and under each
of the Security Documents, and the payment of any amounts which the Trustee is directed to rebate

respect to Article VIII hereof) shall be paid to the Company.

not cause the interest on the Bonds to be included in the gross income of the Bondholders for
federal income tax purposes.

     (i) The Company shall maintain copies of all bills, invoices or other evidences of items of
cost as shall constitute a basis for any payment of Project Costs out of Bond Proceeds or other

Project is in a condition wherein its operation is not negatively affected and the Company is
diligently pursuing completion.

     Section 4.04. Conditions of Final Draw. Notwithstanding any provision of Section 4.02
to the contrary, the Trustee shall hold in the Project Costs Account an amount equal to 5% of the

     (b) If the condemnation award or insurance claim is less than $100,000, the Trustee shall pay
the Net Proceeds to the Company. If the condemnation award or insurance claim exceeds $100,000,
all Net Proceeds of the condemnation award or insurance claim shall be retained by the Trustee and
deposited in the Condemnation and Awards Fund. The Trustee shall apply the Net Proceeds to payment
of the cost of repair, replacement, rebuilding or restoration upon compliance with Section 3.04.
If the Net Proceeds are not sufficient to pay such costs in full, the Company shall pay that
portion of the cost in excess of the amount of the Net Proceeds and shall complete such repair,
replacement, rebuilding or restoration as provided in Section 3.04.

     (c) The Company shall not, by reason of the payment of any costs of repair, rebuilding,
replacement or restoration, be entitled to any reimbursement from the Issuer or any abatement or
diminution of the amounts payable hereunder. Any balance of Net Proceeds remaining in the
Condemnation and Awards Fund after payment of all costs of any repair, rebuilding, replacement or
restoration and after completion of the same shall be paid into the Bond Fund and used to redeem
Bonds pursuant to Section 2.02(f) or, if there are no Outstanding Bonds, to the Company.

     (d) All buildings, improvements and equipment acquired in the repair, rebuilding, replacement
or restoration of the Project, together with any interests in land acquired by the Company
necessary for such restoration, shall be deemed a part of the Project and available for use and
occupancy by the Company without the payment of any additional amounts other than those provided
herein except as otherwise allowed herein, provided that no land, interest in land, buildings

48

 

or
improvements shall be acquired subject to any lien or encumbrance except as otherwise allowed
herein.

     Section 6.08. Maintenance of Facility; Insurance. The Company shall:

     (a) Keep all of the Facility, whether leased or owned, in all material respects in good
condition, repair and working order (ordinary wear and tear excepted) and from time to time make or
cause to be made all needed and proper repairs, renewals, replacements, additions and improvements
so that the business carried on in connection therewith may be properly and advantageously
conducted at all times;

     (b) Maintain and operate or cause the Facility to be maintained and operated in accordance
with accepted standards applicable to facilities of the type similar to the Facility, and comply
with all material contractual obligations, provided that if the Company is prevented or delayed for
any period of time by an Event of Force Majeure in complying with such obligations, such
obligations will be suspended while such conditions exist; and

     (c) Maintain with good, reputable and financially sound insurance underwriters insurance of
such nature and in such amounts as is customarily maintained by companies engaged in the same or
similar business and such other insurance as may be required by law or as may be reasonably
required in the Security Documents.

     Section 6.09. Inspection of Facility. In the event of default, the Trustee and its
duly authorized agent shall have the right, upon reasonable prior notice and during normal business
hours, to enter upon and to examine and inspect the Facility, together with such rights of access
to the Facility as may be reasonably necessary for the proper maintenance of the Facility in the
event of failure by the Company to perform its obligations under this Loan and Trust Agreement or
any other Security Document in the event the Company’s failure continues after having received
notice and an opportunity to cure (to the extent provided in this Loan and Trust Agreement or the
applicable Security Document). The Company will further permit the Issuer, or its duly authorized
agent, at all reasonable times to enter upon the Facility but solely for the purpose of assuring
that the Company is operating the Facility, or is causing the Facility to be operated, as a
qualified “project” under the Act consistent with the purposes set forth in the recitals to this
Loan and Trust Agreement and with the public purposes of the Issuer, and not for any purpose of
assuring the proper maintenance or repair of the Facility as such latter obligation is and shall
remain solely the obligation of the Company. The Company shall keep proper records with respect to
the Facility and the Company’s operations as required by law, and the Trustee and the Issuer shall
also be permitted, at all reasonable times, upon notice to the Company, to examine the books and
records of the Company with respect to compliance by the Company with its obligations hereunder and
under each other Security Document to which it shall be a party. The Company shall provide to an
Inspecting Engineer and an Independent Accountant such information as may be reasonably necessary
to enable an Inspecting Engineer or an Independent Accountant to perform any acts to be taken by
either under this Loan and Trust Agreement or any other Security Document. In connection with such
inspections or examinations, the Trustee shall, on behalf of itself, its agents and
representatives, comply and cause its agents and representatives to comply, with all reasonable
rules and regulations adopted by the Company including a requirement that such person inspecting or
visiting the Facility sign a statement agreeing to assume the risk of the inspection or visitation
but not the risk of injury due to the intentional or negligent acts of the Company. In connection
with

49

 

such inspections or examinations and unless otherwise required by applicable law or
regulation, the Trustee agrees not to disclose or use any confidential information of the Company
or any of its licensors other than for the purpose for which it was furnished and consistent with
any applicable licensing agreement, except that after the
occurrence of an Event of Default any successor Company or other operator of the Facility may use
such confidential information but only for the purpose of operating the Facility and for no other
purpose. The Trustee shall have no obligation for nondisclosure with respect to any information
which may be generally available to the public or which becomes available to the public through no
fault of the Trustee, its agents or representatives.

     Section 6.10. Compliance with Zoning Laws. The use of the Facility shall at all times
be and continue to be in full compliance with all applicable zoning laws and ordinances. The

permit or variance without the written consent of the Issuer.

     Section 6.11. Use of Facility and Bond Proceeds. The Company covenants that it will
(i) design, finance, acquire, construct, equip, install, test, operate and maintain the
Bond-financed portion of the Facility as a “solid waste disposal facility” in accordance with
Section 142(a)(6) of the Code and in accordance with the Tax Regulatory Agreement, and (ii) use the
Bond Proceeds only for the purposes and costs permitted therefor under this Loan and Trust
Agreement and the Tax Regulatory Agreement.

     Section 6.12. No Material Impairment of Value. The Company covenants that it will not
knowingly take any action that would impair, in any material respect, the value, utility or
operating capability of the Facility as intended for the purposes of this Loan and Trust Agreement.

     Section 6.13. Facility Operation. The Company agrees to comply with the terms,
covenants and provisions expressed or implied, of all contracts, licenses, franchises and permits
pertaining to, affecting or involving the Facility or the business of the Company, the violation or
breach of which would materially and adversely affect the ability of the Company to fulfill its
obligations hereunder and under any other Security Document, and the agreements to which the
Company is now or hereafter a party respecting the operation of the Facility.

     Section 6.14. Licenses and Permits. The Company covenants and agrees to obtain and
maintain all material licenses or Government permissions necessary to acquire, construct, equip and
install the Project and operate the Facility.

     Section 6.15. Title to Property. The Company shall maintain title to all property it purports to own to the extent that failure to
do so would materially and adversely affect the Company’s ability to operate the Facility.

     Section 6.16. Payment of Taxes. The Company shall pay or caused to be paid all taxes
and Government charges of any kind which are assessed against the Facility and the Company, and to
pay or cause to be paid promptly any payment in lieu of taxes that may be negotiated between the
Company and the County.

material respects with all terms and conditions of the required permits, licenses and
authorizations and all other limitations, restrictions, conditions, standards, prohibitions,
requirements, obligations, schedules and timetables contained in the Environmental Laws.

     Section 6.19. Indemnification. The Company agrees to defend, indemnify and save
harmless the Issuer and the Trustee and each of their respective officers, agents and employees
from and against any and all losses, damages, costs, charges, expenses (including attorney’s fees),
causes of action, suits, claims, demands, judgments and liabilities arising from:

     (a) Any injury to or death of any person or damage to property in or upon the Facility or
growing out of or connected with the use, nonuse, condition or occupancy of the Facility;

     (b) Violation of any agreement or condition of this Loan and Trust Agreement, except those
knowingly violated by the Issuer or the Trustee;

     (c) Violation of any contract, agreement or restriction by the Company relating to the

     (e) Any statement or information relating to the expenditure of the Bond Proceeds contained in
the “Tax Regulatory Agreement” or similar document furnished by the Company to the Issuer or the
Trustee which, at the time made, is misleading, untrue or incorrect in any material respect;

     (f) Any statement or information furnished to the original purchaser(s) of the Bonds by the
Company;

     (g) Any liability arising under any applicable federal, state or local environmental law
relating to the Facility or the Bonds, not resulting from the negligence or willful misconduct of
the Issuer or the Trustee; and

51

 

     (h) Any other event or circumstance relating to the Facility or the Bonds not described above
not resulting from the negligence or willful misconduct of the Issuer or the Trustee.

     Section 6.20. Assurance of Tax Exemption. In order to assure that the interest on the
Bonds shall at all times be excluded from gross income for federal income tax purposes, the Company
covenants with the Issuer, the Trustee and all Bondowners that it will comply with and fulfill each
of the requirements and conditions of the Tax Regulatory Agreement.

     Section 6.21. Business of Company. The Company shall engage in no business or
enterprise other than the design, acquisition, construction, equipping, installation, testing,
operating, maintenance and management of the Facility or Related Facilities, the performance of its
obligations under this Loan and Trust Agreement and each other Security Document to which it shall
be a party (and all related agreements to the Facility and its financing, construction and
operation) and activities in furtherance thereof or ancillary or reasonably related thereto.

     Section 6.22. Existence; Compliance with Laws; Maintenance of Business; Taxes. The
Company shall:

     (a) maintain its licenses, permits, rights and franchises;

     (b) comply in all material respects with all Requirements of Law;

except to the extent and so long as the same are being contested in good faith by appropriate
proceedings, with adequate reserves having been provided;

     (d) continue to be a limited liability company subject to service of process in the State and
either organized under the laws of the State, or organized under the laws of any other state of the
United States and duly qualified to do business as a foreign corporation in the State;

     (e) not liquidate, wind-up or dissolve or otherwise dispose of all or substantially all of its
property, business or assets remaining after the execution and delivery of this Loan and Trust
Agreement; and

     (f) not consolidate with or merge into another corporation or permit one or more corporations
to consolidate with or merge into it. The Company may, however, after the Completion Date, without
violating the foregoing, but upon thirty (30) days prior written notice to the Issuer and the
Trustee, consolidate with or merge into another corporation or permit one or more corporations to
consolidate with or merge into it, or sell or otherwise transfer all or substantially all of its
property, business or assets to another such corporation (and thereafter liquidate, wind-up or
dissolve or not, as the Company may elect) if:

     (i) immediately after giving effect to such transaction, no Event of Default, nor any
event which, after notice or lapse of time or both, would become an Event of Default, shall
have happened and be continuing, and the Company would not thereby be in default in the
payment, performance or observance of any payment, agreement, covenant or obligation under
this Loan and Trust Agreement or any other Security Document;

52

 

     (ii) either (A) the Company is the surviving, resulting or transferee corporation, as
the case may be, and, unless the Trustee shall otherwise consent in writing, the resulting
corporation has a Net Worth at least equal to the Net Worth of the Company immediately prior
to such merger or consolidation, or (B) in the event that the Company is not the surviving,
resulting or transferee corporation:

     (1) such corporation is subject to service of process in the State and either
organized under the laws of the State, or organized under the laws of any other
state of the United States and duly qualified to do business as a foreign
corporation in the State;

     (2) such corporation assumes in writing all of the obligations of the Company
contained in this Loan and Trust Agreement and all other Security Documents to which
the Company shall be a party;

     (3) in the Opinion of Counsel, (y) such corporation shall be bound by all of
the terms applicable to the Company of this Loan and Trust Agreement and all other
Security Documents to which the predecessor Company corporation shall have
been a party, and (z) such action does not legally impair the security for the
Owners of the Bonds afforded by the Security Documents; and

     (4) in the opinion of Bond Counsel, such action will not cause the interest on
the Bonds to cease to be excludable from gross income for federal income tax
purposes.

     Section 6.23. Continuing Disclosure Agreement. The Issuer hereby acknowledges that
the Company and the Trustee have entered into the Continuing Disclosure Agreement under which the

the Trustee, all in accordance with the provisions of the Continuing Disclosure Agreement.
Notwithstanding any other provision of this Loan and Trust Agreement, any failure by the Company or
the Trustee to comply with any provision of the Continuing Disclosure Agreement shall not be an
Event of Default under this Loan and Trust Agreement or any other Security Document.

POWERS AND DUTIES OF TRUSTEE

     Section 7.01. Trustee; Appointment and Acceptance of Duties. Wells Fargo Bank, N.A.,
Lincoln, Nebraska, is hereby appointed as Trustee. The Trustee shall signify its acceptance of the

be appointed to act as Registrar.

     The Registrar, immediately upon such appointment, shall signify its acceptance of the duties

Loan and Trust Agreement by written instrument of acceptance deposited with the Issuer and the
Trustee.

     The Issuer will cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will:

     (i) hold all sums held by it for the payment of principal of (and premium, if any) or
interest on the Bonds in trust for the benefit of the persons entitled thereto until such
sums shall be paid to such persons or otherwise disposed of as herein provided; and

     (ii) at any time during the continuance of any default, upon the written request of the

respective agencies of the Issuer for the payment of the interest on and principal, or Redemption
Price of the Bonds.

     Section 7.03. Responsibilities of Fiduciaries. The recitals of fact herein and in the

by the Trustee upon the occurrence of an Event of Default, no Fiduciary shall be under any
obligation or duty to perform any act which would involve it in expense or liability or to
institute or defend any suit in respect hereof, or to advance any of its own moneys, unless

duties hereunder except for its own negligence or default. No Fiduciary shall be under any
responsibility or duty with respect to the application of any moneys paid to any one of the others.

54

 

     Section 7.04. Evidence on Which Fiduciaries May Act. The Trustee, the Registrar and
any Paying Agent shall be protected in acting upon any Company’s Certificate, notice, resolution,
request, consent, order, certificate, report, opinion, bond or other paper or document believed by
it to be genuine, and to have been signed or presented by the proper party or parties. Any
Fiduciary may consult with counsel, who may or may not be counsel to the Issuer, and the opinion or
advice of such counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it under this Loan and Trust Agreement in good faith and in
accordance herewith.

     Whenever any Fiduciary shall deem it necessary or desirable that a matter be proved or
established prior to taking, suffering or omitting any action under this Loan and Trust Agreement,
such matter (unless other evidence in respect thereof be herein specifically prescribed) may be
deemed to be conclusively proved and established by a certificate of an Authorized Officer of the
Issuer, and such certificate shall be full warrant for any action taken, suffered or omitted in
good faith under the provisions of this Loan and Trust Agreement upon the faith thereof, but in its
discretion such Fiduciary may in lieu thereof accept other evidence of such fact or matter or may
require such further or additional evidence as to it may seem reasonable.

     Except as otherwise expressly provided in this Loan and Trust Agreement, any request, order,
notice or other direction required or permitted to be furnished pursuant to any provision thereof
by the Issuer to any Fiduciary shall be sufficiently executed if executed in the name of the Issuer
by an Authorized Officer of the Issuer.

     The Trustee shall be under no obligation to exercise any of the rights or powers vested in it
by this Loan and Trust Agreement at the request or direction of any of the Bondowners pursuant to
this Loan and Trust Agreement, unless such Bondowners shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction.

     The Trustee shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to
examine the books, records and premises of the Issuer, personally or by agent or attorney.

     The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder
either directly or by or through agents or attorneys and the Trustee shall not be responsible for
any misconduct or negligence on the part of any agent or attorney appointed with due care by it
hereunder.

     Section 7.05. Compensation of Fiduciaries.

     (a) The Trustee shall be entitled to payment and reimbursement for its reasonable fees for its
services rendered hereunder as and when the same become due and such reasonable expenses as are
incurred by the Trustee in connection with such services as and when the same become due as agreed
upon with the Issuer.

55

 

     (b) The Trustee and each Fiduciary shall be entitled to payment and reimbursement for their
reasonable fees for services rendered under this Loan and Trust Agreement and such reasonable
expenses as are incurred by them in connection with such services as and when the same become due
as agreed upon with the Issuer in the amounts and subject to the limitations specified in this Loan
and Trust Agreement.

     Section 7.06. Permitted Acts and Functions. The Trustee, the Registrar and any Paying
Agent may buy, own, hold and sell any bonds of the Issuer, whether heretofore or hereafter issued
or created and may engage or be interested in any financial or other transaction with the Issuer,
with like effect and with the same rights it would have if it were not such Fiduciary. Any
Fiduciary may act as depositary for and permit any of its officers or directors to act as a member
of, or in any other capacity with respect to any committee formed to protect the rights of
Bondowners or to effect or aid in any reorganization growing out of the enforcement of the Bonds or
this Loan and Trust Agreement, whether or not any such committee shall represent the Owners of a
majority in Principal Amount of the Bonds then Outstanding.

     Section 7.07. Resignation of Trustee. The Trustee may at any time resign and be
discharged of the duties and obligations created by this Loan and Trust Agreement by giving not
less than sixty (60) days’ written notice to the Issuer and mailing notice thereof by first-class
mail, postage prepaid, at the Trustee’s expense to the Owners of all Outstanding Bonds, specifying
the date when such resignation shall take effect, and such resignation shall take effect upon the
day specified in such notice unless previously a successor shall have been appointed, as provided
in Section 7.09, in which event such resignation shall take effect immediately on the appointment
of such successor. In no event, however, shall such a resignation take effect until a successor
Trustee has been appointed pursuant to Section 7.09.

     Section 7.08. Removal of Trustee. The Trustee shall be removed and replaced by the
Issuer (at the direction of the Company) if at any time so requested by an instrument or concurrent
instruments in writing, filed with the Trustee and the Issuer. The Issuer may remove and replace
the Trustee at any time (at the direction of the Company), except during the existence of an Event
of Default (or after the occurrence of an event which, upon the giving of notice or the passage of
time or both, may become an Event of Default), with or without cause, subject to the provisions of
Section 7.09 and the opinion of the Issuer that such removal and replacement of the Trustee is not
detrimental to the Bondowners, by filing with the Trustee an instrument signed by an Authorized
Officer of the Issuer. Such instrument shall provide for an effective date not less than thirty
(30) days after the date of
delivery to the Trustee, and shall make such other provisions for transfer of duties to the
successor trustee as shall be deemed reasonably necessary in the sole discretion of the Issuer (at
the direction of the Company). The Trustee is hereby relieved of any and all liability by the
Issuer to the Bondowners resulting from any such removal and replacement by the Issuer without
cause. Notwithstanding anything herein to the contrary, a majority in principal amount of
Bondholders may direct the Issuer to remove the Trustee subject to the provisions hereof.

     Section 7.09. Appointment of Successor Trustee.

56

 

     (a) In case at any time the Trustee shall resign or shall be removed or shall become incapable
of acting, or shall be adjudged as bankrupt or insolvent, or if a receiver, liquidator or
conservator of the Trustee, or of its property, shall be appointed, or if any public officer shall
take charge or control of the Trustee, or of its property or affairs, the Issuer covenants and
agrees that it will thereupon appoint a successor Trustee (acceptable to the Company or to a
majority in principal amount of Bondholders).

     (b) If in a proper case no appointment of a successor Trustee shall be made pursuant to the
foregoing provisions of this Section within 45 days after the Trustee shall have given to the
Issuer written notice, as provided in Section 7.07, or after a vacancy in the office of the Trustee
shall have occurred by reason of its inability to act, the Trustee or the Owner of any Bond may
apply to any court of competent jurisdiction to appoint a successor Trustee. Such court may
thereupon, after such notice, if any, as such court may deem proper and prescribe, appoint a
successor Trustee.

     (c) Any Trustee appointed under the provisions of this Section in succession to the Trustee
shall be a trust company or bank having the powers of a trust company within or outside the State,
having capital and surplus aggregating at least $50,000,000 or having at least $500,000,000 of
assets under trust administration if there be such a trust company or bank willing and able to
accept the office on reasonable and customary terms and authorized by law to perform all of the
duties imposed upon it by this Loan and Trust Agreement.

     Section 7.10. Transfer of Rights and Property to Successor. Any successor Trustee
appointed under this Loan and Trust Agreement shall execute, acknowledge and deliver to its
predecessor Trustee, and also to the Issuer, an instrument accepting such appointment, and
thereupon such successor Trustee, without any further act, deed or conveyance, shall become fully
vested with moneys, estates, properties, rights, powers, duties and obligations of such predecessor
Trustee, including all Credit Facilities and liquidity facilities, with like effect as if
originally named as Trustee; but the Trustee ceasing to act shall nevertheless, on the written
request of the Issuer or of the successor Trustee, execute, acknowledge and deliver such
instruments of conveyance and further assurance and do such other things as may reasonably be
required for more fully and certainly vesting and confirming in such successor Trustee all the
right, title and interest of the predecessor Trustee in and to any property held by it under this
Loan and Trust Agreement, and shall pay over, assign and deliver to the successor Trustee any money
or other property subject to the trusts and conditions
herein set forth, subject nevertheless to its lien, if any, provided for in Section 7.05. Should
any deed, conveyance or instrument in writing from the Issuer be required by such successor Trustee
for more fully and certainly vesting in and confirming to such successor Trustee any such estates,
rights, powers and duties, any and all such deeds, conveyances and instruments in writing shall, on
request and so far as may be authorized by law, be executed, acknowledged and delivered by the
Issuer. Any such successor Trustee shall promptly notify the Registrar and each Paying Agent of
its appointment as Trustee.

     Section 7.11. Merger, Conversion or Consolidation. Any company into which any
Fiduciary may be merged or converted or with which it may be consolidated or any company resulting
from any merger, conversion or consolidation to which it shall be a party or any company to which
any Fiduciary may sell or transfer all or substantially all of its corporate trust business, shall
be the successor to such Fiduciary without the execution or filing of any paper or the performance
of any further act, provided that any such successor shall be a bank with trust powers or trust
company or a national banking association with trust powers and shall be qualified to be a

57

 

successor to such Fiduciary under Section 7.09 or Section 7.12 and authorized by law to perform all
the duties imposed upon it by this Loan and Trust Agreement.

     Section 7.12. Resignation or Removal of Registrar and Paying Agents and Appointment of
Successors. Any Registrar or Paying Agent may at any time resign and be discharged of the
duties and obligations created by this Loan and Trust Agreement by giving at least sixty (60) days’
written notice to the Issuer, the Company and the Trustee. Any Registrar or Paying Agent may be
removed at any time by an instrument filed with such Fiduciary and the Trustee and signed by an
Authorized Officer of the Issuer. Any initial or successor Paying Agent shall be appointed by
resolution of the Issuer and shall be a bank with trust powers or trust company organized under the
laws of any state of the United States or a national banking association with trust powers, having
capital and surplus aggregating at least $50,000,000 or having at least $500,000,000 of assets
under trust administration, and willing and able to accept the office of Paying Agent on reasonable
and customary terms and authorized by law to perform all the duties imposed upon it by this Loan
and Trust Agreement. Any successor Registrar shall be appointed by resolution of the Issuer and
shall be a bank with trust powers or trust company organized under the laws of the State or a
national banking association with trust powers doing business in the State and having capital and
surplus aggregating at least $50,000,000 or having at least $500,000,000 of assets under trust
administration, and willing and able to accept the office of Registrar on reasonable and customary
terms and authorized by law to perform all duties imposed upon it by this Loan and Trust Agreement.

     In the event of the resignation or removal of any Paying Agent, such Paying Agent shall pay
over, assign and deliver any moneys held by it to its successor, or if there be no successor then
appointed, to the Trustee until such successor be appointed.

     Section 7.13. Co-Trustees. It is the purpose of this Loan and Trust Agreement that
there shall be no violation of any law of any jurisdiction (including particularly the law of the
State) denying or restricting the right of banking corporations or associations to transact
business as Trustee in such jurisdiction. It is recognized that in case of litigation under this
Loan and Trust Agreement, and in particular in case of the enforcement thereof on default, or in
case the Trustee deems that by reason of any present or future law of any jurisdiction it may not
exercise any of the powers, rights or remedies herein granted to the Trustee or take any other
action which may be desirable or necessary in connection therewith, it may be necessary that the
Trustee appoint an additional individual or institution as a separate or co-trustee. The following
provisions of this Section shall govern the appointment of separate or co-trustees.

     The Trustee may, in its discretion, appoint one or more additional individuals or institutions
as separate or co-trustees by written instrument. The Trustee may from time to time, in writing,
prescribe the powers, duties and rights of each separate or co-trustee and may remove any such
separate or co-trustee. Each and every remedy, power, right, claim, demand, cause of action,
immunity, estate, title, interest and lien expressed or intended by this Loan and Trust Agreement
to be exercised by or vested in or conveyed to the Trustee with respect thereto shall, to the
extent provided by the Trustee, be exercisable by and vest in such separate or co-trustee but only
to the extent necessary to enable the separate or co-trustee to exercise the powers, rights and
duties so provided by the Trustee, and every covenant and obligation necessary to the exercise
thereof by such separate or co-trustee shall run to and be enforceable by either the Trustee or
such separate or co-trustee.

58

 

     Should any deed, conveyance or other instrument from the Issuer be required by the separate
trustee or co-trustee so appointed by the Trustee for more fully and certainly vesting trusts,
duties and obligations, any and all such deeds, conveyances and other instruments shall on request,
be executed, acknowledged and delivered by the Issuer. In case any separate trustee or co-trustee,
or a successor to either, shall die, become incapable of acting, resign or be removed, all the
estates, properties, rights, powers, trusts, duties and obligations of such separate trustee or
co-trustee, so far as permitted by law, shall vest in and be exercised by the Trustee until the
appointment of a new trustee or successor to such separate trustee or co-trustee.

     Section 7.14. Recordkeeping. The Trustee shall keep proper books, records and account
in which complete and correct copies of all certificates and documents required to be filed with it
hereunder shall be maintained and preserved for a reasonable period of time. The Trustee shall
make such books and records available for inspection by the Issuer during reasonable hours and
under reasonable conditions. The Issuer shall have the right to require the Trustee to furnish
such documents as the Issuer, in its sole discretion and from time to time, deems necessary to
determine that the provisions of this Loan and Trust Agreement have been complied with and to
satisfy the Issuer’s statutory recordkeeping requirements.

ARTICLE VIII

BOND DEFAULTS AND REMEDIES

     Section 8.01. Bond Defaults Defined. If any of the following events occur, it is
hereby defined as and declared to be and to constitute a “Bond Default”:

     (a) Payment of any interest on any Bond shall not be made when and as that interest shall
become due and payable;

     (b) Payment of the principal of or any premium on any Bond shall not be made when and as that
principal or premium shall become due and payable, whether at stated maturity, by redemption,
pursuant to any mandatory sinking fund requirements, by acceleration or otherwise; or

     (c) A “Loan Default” shall occur under Section 9.01.

     Section 8.02. Acceleration. Upon the occurrence of a Bond Default set forth in
Section 8.01, the Trustee may, and upon the written request of the Bondowners of more than 50% of
the aggregate principal amount of Bonds then Outstanding shall, by notice in writing delivered to
the Issuer and the Company, declare the principal of all Bonds then Outstanding and the accrued
interest thereon immediately due and payable, and such principal and interest shall thereupon
become and be immediately due and payable.

     Section 8.03. Remedies. Upon the occurrence of a Bond Default, the Trustee, may, in
addition to acceleration as provided in Section 8.02, pursue any available remedy by action at law
or suit in equity to enforce the payment of the principal of, premium, if any, and interest on the
Bonds. In exercising the rights given the Trustee under this Article, the Trustee shall take such
action as, in the judgment of the Trustee applying the standards described in Section 7.01, would
best serve the interests of the Bondowners.

59

 

     If any Bond Default shall have occurred, and if requested so to do by the Bondowners of more
than 50% in aggregate principal amount of Bonds then Outstanding and if indemnified, the Trustee
shall be obliged to exercise such one or more of the rights and powers conferred by this Article as
the Trustee, being advised by counsel, shall deem most expedient in the interest of the Bondowners.

     No remedy by the terms of this Loan and Trust Agreement conferred upon or reserved to the
Trustee (or to the Bondowners) is intended to be exclusive of any other remedy, but each and every
such remedy shall be cumulative and shall be in addition to any other remedy given to the Trustee
or to the Bondowners hereunder or now or hereafter existing at law or in equity or by statute.

     No delay or omission to exercise any right or power accruing upon any default or event of
default shall impair any such right or power or shall be construed to be a waiver of any such
default or event of default or acquiescence therein; and every such right and power may be
exercised from time to time and as often as may be deemed reasonable or prudent.

     No waiver of any default or Bond Default hereunder, whether by the Trustee pursuant to the
provisions of Section 8.10 or by the Bondowners, shall extend to or shall affect any subsequent
default or event of default or shall impair any rights or remedies consequent thereon.

     Section 8.04. Right of Bondowners to Direct Proceedings. Anything herein to the
contrary notwithstanding, the Bondowners of a majority in aggregate principal amount of Bonds then
Outstanding shall have the right, at any time, by an instrument or instruments in writing executed
and delivered to the Trustee, to direct the time, method and place of conducting all proceedings to
be taken in connection with the enforcement of the terms and conditions hereof, or for the
appointment of a receiver or any other proceedings hereunder, provided that such direction shall
not be otherwise than in accordance with the provisions of law and of this Loan and Trust
Agreement.

     Section 8.05. Waiver of Certain Rights. Upon the occurrence of a Bond Default, to the
extent that such rights may then lawfully be waived, neither the Issuer nor anyone claiming through
it or under it, shall set up, claim or seek to take advantage of any moratorium, stay, extension or
redemption laws now or hereafter in force to prevent or hinder the enforcement of this Loan and
Trust Agreement, but the Issuer, for itself and all who may claim through or under it hereby
waives, to the extent that it lawfully may do so, the benefit of all such laws to which it may be
entitled by law.

     Section 8.06. Application of Moneys. All moneys received by the Trustee pursuant to
any right given or action taken under the provisions of this Article shall, after payment of the
cost and expenses of the proceedings resulting in the collection of such moneys and of the
expenses, liabilities and advances incurred or made by the Trustee, be deposited into the Bond Fund
and all moneys held or deposited in the Bond Fund during the continuance of a Bond Default shall be
applied as follows:

     (a) Unless the principal of all the Bonds has become or shall have been declared due and
payable, all such moneys shall be applied:

60

 

     First: To the payment to the persons entitled thereto of all installments of
interest then due on the Bonds, in the order of the maturity of the installments of such
interest including interest (to the extent permitted by law) on overdue installments of
interest, and, if the amount available shall not be sufficient to pay in full any particular
installment, then to
the payment ratably, according to the amounts due on such installment, to the persons
entitled thereto without any discrimination or privilege; and

     Second: To the payment to the persons entitled thereto of the unpaid principal
of any of the Bonds which shall have become due (other than Bonds called for redemption for
the payment of which moneys are held pursuant to the provisions hereof), in the order of
their due dates, with interest (to the extent permitted by law) on such Bonds from the
respective dates upon which they became due and, if the amount available shall not be
sufficient to pay in full Bonds due on any particular date, together with such interest,
then to the payment ratably, according to the amount of principal, with interest (to the
extent permitted by law) on such premiums from the respective dates on which such premiums
became due, due on such date, to the persons entitled thereto without any discrimination or
privilege.

     Third: To the payment to the persons entitled thereto of the unpaid premium,
if any on any of the Bonds which have been called for redemption, in the order of the
redemption dates, with interest (to the extent permitted by law) on such premiums from the
respective dates on which such premiums became due, and, if the amount available shall not
be sufficient to pay in full the premiums due on any particular redemption date, together
with such interest, then to the payment ratably, according to the premium due on such date,
to the persons entitled thereto without any discrimination or privilege.

     (b) If the principal of all the Bonds shall have become due or shall have been declared due
and payable, all such moneys shall be applied first to the payment of the principal and interest
then due and unpaid upon all of the Bonds, without preference or priority of principal over
interest or of interest over principal, or of any installment of interest, or of any Bond over any
other Bond, ratably, according to the amounts due respectively for principal and interest, to the
persons entitled thereto without any discrimination or privilege, and secondly to the payment of
the premium, if any, then due, ratably to the persons entitled thereto without any discrimination
or privilege.

     (c) If the principal of all the Bonds shall have been declared due and payable, and if such
declaration shall thereafter have been rescinded and annulled under the provisions of this Article
then, subject to the provisions of subsection (b) of this Section in the event that the principal
of all the Bonds shall later become due or be declared due and payable, the moneys shall be applied
in accordance with the provisions of subsection (a) of this Section.

     Whenever moneys are to be applied pursuant to the provisions of this section, such moneys
shall be applied at such times from time to time as the Trustee shall determine, having due regard
to the amount of such moneys available for application and the likelihood of additional moneys
becoming available for such application in the future. Whenever the Trustee shall apply such
funds, it shall fix the date (which shall be an Payment Date unless it shall deem another date more
suitable) upon which such application is to be made and upon such date interest on the amounts of
principal to be paid on such dates shall cease to accrue. The Trustee shall give such notice as it
may deem appropriate of the deposit and shall not be required to make payment to the Bondowner of
any

61

 

unpaid Bond until such Bond shall be presented to the Trustee for appropriate endorsement or
for cancellation if fully paid.

     Section 8.07. Remedies Vested in Trustee. All rights of action (including the right
to file proof of claims) under this Loan and Trust Agreement or under any of the Bonds may be
enforced by the Trustee without the possession of any of the Bonds or the production thereof in any
trial or other proceedings relating thereto and any such suit or proceeding instituted by the
Trustee shall be brought in its name as Trustee without the necessity of joining as plaintiffs or
defendants any Bondowners appertaining thereto, and any recovery of judgment shall, subject to the
provisions of Section 8.06, be for the equal and ratable benefit of the Bondowners of the Bonds
Outstanding.

     Section 8.08. Rights and Remedies of Bondowners. No Bondowner shall have any right to
institute any suit, action or proceeding in equity or at law for the enforcement of this Loan and
Trust Agreement or for the execution of any trust thereof or for the appointment of a receiver or
any other remedy hereunder, unless a Bond Default has occurred nor unless the Bondowners of at
least a majority in aggregate principal amount of Bonds then Outstanding shall have made written
request to the Trustee and shall have offered it reasonable opportunity either to proceed to
exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own
name nor unless also the Trustee shall thereafter fail or refuse to exercise the powers
hereinbefore granted, or to institute such action, suit or proceeding in its own name nor unless
also they have offered to the Trustee indemnity; and such notification, request and offer of
indemnity are hereby declared in every case at the option of the Trustee to be conditions precedent
to the execution of the powers and trust of this Loan and Trust Agreement, and to any action or
cause of action for the enforcement of this Loan and Trust Agreement, or for the appointment of a
receiver or for any other remedy hereunder; it being understood and intended that no one or more
Bondowners shall have any right in any manner whatsoever to affect, disturb or prejudice the
security of this Loan and Trust Agreement by its, his or their action or to enforce any right
hereunder except in the manner herein provided and that all proceedings at law or in equity shall
be instituted, had and maintained in the manner herein provided and for the equal benefit of the
Bondowners of all Bonds then Outstanding. Nothing herein contained shall, however, affect or
impair the right of any Bondowner to enforce the payment of the principal of and interest on any
Bond at and after the stated maturity thereof, or the obligation of the Issuer to pay the principal
of, premium, if any, and interest on each of the Bonds issued hereunder to the respective
Bondowners at the time, place, from the source and in the manner herein and in said Bonds
expressed.

     Section 8.09. Termination of Proceedings. In case the Trustee shall have proceeded to
enforce any right hereunder and such proceedings shall have been discontinued or abandoned for any
reason, or shall have been determined adversely, then and in every such case the Issuer, the
Company and the Trustee shall be restored to their former positions and rights hereunder and all
rights, remedies and powers of the Trustee shall continue as if no such proceedings had been taken.

     Section 8.10. Waivers of Bond Defaults. The Trustee shall waive any Bond Default
hereunder and its consequences and rescind any declaration of maturity of principal of and interest
on the Bonds upon the written request of the Bondowners of a majority in aggregate principal amount
of all of the Bonds then Outstanding, provided however, that there shall not be waived without the
consent of the Bondowners of all the Bonds Outstanding (i) any Bond Default in the payment of the
principal of any outstanding Bonds at the date of maturity specified therein or at the date fixed
for the redemption thereof, or (ii) any Bond Default in the payment when due of the

62

 

interest on any
such Bonds unless, prior to such waiver or rescission, all arrears of interest, with interest (to
the extent permitted by law) on overdue installments of interest at the rate per annum provided in
the Bonds, or all arrears of payments of principal, with interest (to the extent permitted by law)
on overdue principal at the rate per annum provided in the Bonds, as the case may be, and all
expenses of the Trustee in connection with such default shall have been paid or provided for; and
in case of any such waiver or rescission, or in case any proceeding taken by the Trustee on account
of any such default shall have been discontinued or abandoned or determined adversely, then and in
every such case the Issuer, the Trustee and the Bondowners shall be restored to their former
positions and rights hereunder respectively, but no such waiver or rescission shall extend to any
subsequent or other default, or impair any right consequent thereon.

ARTICLE IX

DEBT SERVICE COVERAGE RATIO

     The Company covenants to take all action required to have and maintain a Debt Service Coverage
Ratio of not less than 1.25:1 for each fiscal year commencing with the fiscal year ending in 2008
and based upon the audited financial statements of the Company for each such fiscal year; provided,
however, failure to maintain such Debt Service Coverage Ratio for any fiscal year shall not be an
Event of Default so long as the Senior Lender has waived compliance with debt service coverage
requirements under the Senior Credit Facility and the Company is not in default with respect to any
payments due under this Loan and Trust Agreement or the Note.

ARTICLE X

LOAN DEFAULTS AND REMEDIES

     Section 10.01. Loan Defaults Defined. If any of the following events occur, it is
hereby defined as and declared to be and to constitute a “Loan Default”:

     (a) Default in the due and punctual payment of any installment of principal or any payment of
interest or premium on the Loan or the Note or otherwise due hereunder when and as the same shall
become due and payable, whether upon demand, at maturity, by acceleration or otherwise;

     (b) The Company shall fail to observe or perform any of the covenants, agreements or
conditions of the Company contained in this Loan and Trust Agreement or in the Security Documents
and such failure shall continue for 30 days after either (i) written notice thereof is given by the
Issuer, the Trustee or the Bondowners of more than 50% in aggregate principal amount of the Bonds
at the time Outstanding to the Company, or (ii) any Authorized Officer of the Company has actual
notice thereof;

     (c) Any representation or warranty made by the Company herein or in any of the Security
Documents or in any certificate, document or financial statement delivered to the Issuer shall
prove to have been incorrect in any material adverse respect as of the time when made or given;

63

 

     (d) The Company shall (i) become insolvent or take or fail to take any action which
constitutes an admission of inability to pay its debts as they mature; (ii) make an assignment for
the benefit of creditors; (iii) petition or apply to any tribunal for the appointment of a
custodian, receiver or any trustee for the Company or a substantial part of its respective assets;
(iv) suffer any such custodianship, receivership or trusteeship to continue undischarged for a
period of thirty days or more; (v) commence any proceeding under any bankruptcy, reorganization,
arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction,

     (e) Any Person shall (i) petition or apply to any tribunal for the appointment of a custodian,
receiver or any trustee for the Company or a substantial part of its assets which continues

bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or liquidation law or
statute of any jurisdiction, whether now or hereafter in effect, in which an order for relief is
entered or which remains undismissed for a period of 60 days or more.

     Section 10.02. Certain Notices to Company. In the event that the Trustee fails to
receive when due any payment of principal or interest by the Company on the Loan, the Trustee shall
immediately give written notice thereof by telefax, mail, postage prepaid, or by messenger to the
Company specifying such failure. Such notice, however, shall not be a condition precedent to the
exercise of any remedy hereunder, and failure to give such notice shall not preclude such default
from being a Loan Default.

     Section 10.03. Acceleration Upon Certain Circumstances. Upon the occurrence of a Loan
Default, the Trustee may, by written notice to the Company, declare the Loan to be immediately due
and payable and/or may pursue any available remedy by suit at law or in equity to insure or realize
the payment of the principal of, premium, if any, and interest under this Loan and Trust Agreement.
In the event that the Trustee shall accelerate the Bonds pursuant to Section 8.02, the Trustee
shall, by
written notice to the Company, declare the entire outstanding principal balance of the Loan
together with all interest accrued thereon to be due and payable, and such principal and interest
shall thereupon become and be immediately due and payable.

     Section 10.04. Remedies. Whenever any Loan Default shall have occurred, but subject
to the Subordination Agreement, the Trustee may declare all Loan Repayments for the remainder of
the term of this Loan and Trust Agreement (being an amount equal to that necessary to pay in full
all Outstanding Bonds, assuming acceleration of the Bonds hereunder, and all other indebtedness
hereunder) to be immediately due and payable by the Company and may declare the entire outstanding
principal balance of the Loan, together with all interest accrued thereon, to be due and payable,
provided, however, that there may be no acceleration of the Loan unless there is an acceleration of
the Bonds hereunder; but any acceleration of the Bonds hereunder shall result in an acceleration of
the Loan. The provisions of this Section do not limit the application of Section 10.01 or 10.03.
Upon the occurrence of a Loan Default, the Trustee may also take whatever action at law or in
equity may appear necessary or appropriate to collect the Loan Repayments then due and thereafter
to become due or to enforce performance and observance of any obligation, agreement or covenant of
the Company hereunder.

64

 

     Section 10.05. Disposition of Funds. Any amounts collected pursuant to action taken
under Section 10.03 or 10.04 shall be paid into the Bond Fund and applied in accordance with the
provisions of Section 8.06.

     Section 10.06. Manner of Exercise. No remedy conferred upon or reserved to the Issuer
hereunder is intended to be exclusive of any other available remedy or remedies, but each and every
such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or
now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any
right or power occurring upon any default shall impair any such right or power or shall be
construed to be a waiver thereof, but any such right and power may be exercised from time to time
and as often as may be deemed expedient. In order to entitle the Issuer to exercise any remedy
reserved to it in this Article, it shall be necessary to give only such notice as may be herein
expressly required.

     Section 10.07. Attorneys’ Fees and Expenses. In the event the Company should default
under any of the provisions hereof and the Issuer or the Trustee should employ attorneys or incur
other expenses (including the costs and expenses of the Issuer Attorney) for the collection of the
Loan or the enforcement of performance of any obligation or agreement on the part of the Company
hereunder, the Company will on demand pay to the Issuer or the Trustee the reasonable fee of such
attorneys and such other expenses so incurred.

     Section 10.08. Effect of Waiver.
In the event any agreement contained herein should be breached by either party and thereafter
waived by the other party, such waiver shall be limited to the particular breach so waived and
shall not be deemed to waive any other breach.

     Section 10.09. Waiver of Stay or Extension Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the performance of this
Loan and Trust Agreement; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it will not hinder,
delay or impede the execution of any power granted herein to the Issuer or the Trustee, but will
permit the execution of every such power as though no such law had been enacted.

     Section 10.10 Limitation of Actions; Subordination Agreement. Notwithstanding any
provisions of Article VIII, Article IX and Article X, all bond defaults and loan defaults and
related remedies shall be subject to the terms and conditions of the Subordination Agreement.

ARTICLE XI

AMENDMENTS

     Section 11.01. Powers of Amendment. Subject to the Subordination Agreement, the
Issuer, the Trustee and the Company may enter into one or more Supplemental Loan and Trust
Agreements without the consent of the Owners of the Bonds to cure any ambiguity, inconsistency or
omission in this Loan and Trust Agreement. Any other modification or amendment of this Loan and
Trust Agreement and of the rights and obligations of the Issuer and of the Owners of the Bonds in
any

65

 

particular may be made by a Supplemental Loan and Trust Agreement with the written consent
given as hereinafter provided in Section 11.02 of (a) the Owners of at least a majority in
Principal Amount of the Bonds Outstanding at the time such consent is given, and (b) in case less
than all of the several Series of Bonds then Outstanding are affected by the modification or
amendment, the Owners of at least a majority in Principal Amount of the Bonds of each Series so
affected and Outstanding at the time such consent is given; provided, however, that if any such
modification or amendment will, by its terms, not take effect so long as any Bonds of any specified
like Series and maturity remain Outstanding, the consent of the Owners of the Bonds of such Series
and maturity shall not be required and such Bonds shall not be deemed to be Outstanding for the
purpose of any calculation of the Principal Amount of Outstanding Bonds under this Section. No
such modification or amendment shall permit a change in the terms of redemption or maturity of the
principal of any Outstanding Bond or of any installment of interest thereon or a reduction in the
Principal Amount or the Redemption Price thereof or in the rate of interest thereon without the
consent of the Owner of such Bond, or shall reduce the percentages of Bonds the consent of the
Owners of which is required to effect any such modification or amendment. For the purposes of this
Section, a Series shall be deemed to be affected by a modification or amendment of this Loan
and Trust Agreement if the same adversely affects or diminishes the rights of the Owners of Bonds
of such Series. The Trustee may in its discretion determine whether or not, in accordance with the
foregoing provisions, Bonds of any particular Series or maturity would be affected by any
modification or amendment of this Loan and Trust Agreement and any such determination shall be
binding and conclusive on the Issuer and all Owners of Bonds. The Trustee may receive an opinion
of counsel, including a Counsel’s Opinion, as conclusive evidence as to whether Bonds of any
particular Series or maturity would be so affected by any such modification or amendment of this
Loan and Trust Agreement.

     Section 11.02. Consent of Bondowners. Subject to the Subordination Agreement, the
Issuer may at any time adopt a Supplemental Loan and Trust Agreement making a modification or
amendment permitted by the provisions of Section 11.01 to take effect when and as provided in this
Section. A copy of such Supplemental Loan and Trust Agreement (or brief summary thereof or
reference thereto in form approved by the Trustee) together with a request to Bondowners for their
consent thereto in form satisfactory to the Trustee by the Issuer to Bondowners, shall be mailed by
the Trustee by first class mail, postage prepaid, to the Owners of all Outstanding Bonds. Such
Supplemental Loan and Trust Agreement shall not be effective unless and until (a) there shall have
been filed with the Trustee (i) the written consents of Owners of the percentages of the Principal
Amount of Outstanding Bonds specified in Section 11.01, and (ii) a Counsel’s Opinion stating that
such Supplemental Loan and Trust Agreement has been duly and lawfully adopted and filed by the
Issuer in accordance with the provisions of this Loan and Trust Agreement, is authorized or
permitted by this Loan and Trust Agreement, and is valid and binding upon the Issuer and
enforceable in accordance with its terms; and (b) a notice shall have been given as hereinafter in
this Section provided. Each such consent shall be effective only if accompanied by proof of the
holding, at the date of such consent, of the Bonds with respect to which such consent is given,
which proof shall be such as is permitted by Section 11.02. A certificate or certificates by the
Issuer filed with the Trustee that it has examined such proof and that such proof is sufficient in
accordance with Section 11.02 shall be conclusive that the consents have been given by the Owners
of the Bonds described in such certificate or certificates of the Issuer. Any such consent shall
be binding upon the Owner of the Bonds giving such consent and, anything in Section 11.02 to the
contrary notwithstanding, upon any subsequent Owner of such Bonds and of any Bonds issued in
exchange therefor (whether or not such subsequent Owner thereof has notice thereof), unless such
consent is

66

 

revoked in writing by the Owner of such Bonds giving such consent or a subsequent Owner
thereof by filing with the Trustee prior to the time when the written statement of the Issuer
hereinafter in this Section provided for is filed, such revocation. At any time after the Owners
of the required percentages of Bonds shall have filed their consents to the Supplemental Loan and
Trust Agreement, the Issuer shall make and file with the Trustee a written statement that the
Owners of such required percentages of Bonds shall have filed their consents to the Supplemental
Loan and Trust Agreement. Such written statement shall be conclusive that such consents have been
so filed. At any time thereafter, notice, stating in substance that the Supplemental Loan and
Trust Agreement (which may be referred to as a Supplemental Loan and Trust Agreement adopted by the
Issuer on a stated date, a copy of which is on file with the Trustee) has been consented to by the
Owners of the required percentages of Bonds and will be effective as provided in this Section, may
be given to Bondowners by the Issuer by mailing such notice to Bondowners (but failure to mail such
notice shall not prevent such Supplemental Loan and Trust Agreement from becoming effective and
binding as in this Section provided) not more than ninety (90) days after the Owners of the
required
percentages of Bonds shall have filed their consents to the Supplemental Loan and Trust Agreement
and the written statement of the Issuer hereinabove provided for is filed. The Issuer shall file
with the Trustee proof of the mailing of such notice. A transcript, consisting of the papers
required or permitted by this Section to be filed with the Trustee, shall be proof of the matters
therein stated. Such Supplemental Loan and Trust Agreement making such amendment or modification
shall be deemed conclusively binding upon the Issuer, each Fiduciary and the Owners of all Bonds at
the expiration of thirty (30) days after the filing with the Trustee of the proof of the mailing of
such last mentioned notice, except in the event of a final decree of a court of competent
jurisdiction setting aside such Supplemental Loan and Trust Agreement in a legal action or
equitable proceeding for such purpose commenced within such thirty (30) day period; provided,
however, that the Issuer during such thirty (30) day period and any such further period during
which any such action or proceeding may be pending shall be entitled in their absolute discretion
to take such action, or to refrain from taking such action, with respect to such Supplemental Loan
and Trust Agreement as they may deem expedient.

     Section 11.03. Modifications by Unanimous Consent. Subject to the Subordination
Agreement, in addition to Section 11.01, the terms and provisions of this Loan and Trust Agreement
and the rights and obligations of the Issuer and of the Owners of the Bonds thereunder may be
modified or amended in any respect upon the adoption and filing by the Issuer of a Supplemental
Loan and Trust Agreement and the consent of the Owners of all of the Bonds then Outstanding, such
consent to be given as provided in Section 11.02, except that no notice to Bondowners shall be
required.

     Section 11.04. Mailing. Any provision in this Article for the mailing of a notice or
other document to Bondowners shall be fully complied with if such notice of document is mailed
postage prepaid only (a) to each registered owner of Bonds then Outstanding at his or her address,
appearing upon the registration books of the Issuer, and (b) to the Trustee.

     Section 11.05. Exclusion of Bonds. Bonds owned or held by or for the account of the
Issuer shall not be deemed Outstanding for the purpose of consent or other action nor any
calculation of the Principal Amount of Outstanding Bonds provided for in this Article, and the
Issuer shall not be entitled with respect to such Bonds to give any consent or take any other
action provided for taken under this Article. The Issuer shall furnish the Trustee a certificate
of an Authorized Officer of the Issuer, upon which the Trustee may rely, describing all Bonds so to
be excluded.

67

 

     Section 11.06. Notation on Bonds. Bonds delivered after the effective date of any
action taken as in this Article XI provided may, and if the Trustee so determines shall, bear a
notation by endorsement or otherwise in form approved by the Issuer and the Trustee as to such
action, and in that case upon demand of the Owner of any Bond Outstanding at such effective date
and upon presentation of his Bond for the purpose at the principal office of the Trustee, suitable
notation shall be made on such Bond by the
Trustee as to any such action. If the Issuer or the Trustee shall so determine, new Bonds so
modified as in the opinion of the Trustee and the Issuer to conform to such action shall be
prepared and delivered, and upon demand of the Owner of any Bond then Outstanding shall be
exchanged, upon surrender of such Bonds.

ARTICLE XII

Issuer, at the Issuer’s Address; (ii) if to the Company, at the Company’s Address; and (iii) if to

Inspecting Engineer filed with the Issuer and the Trustee following such damage or
destruction (1) the completion of the Facility will be delayed for at least six months, (2)

     (g) If the Bonds are redeemed in part pursuant to this option, the aggregate principal amount
available for redemption shall be allocated by the Trustee among the various maturities in the
proportions (as nearly as practicable given the minimum authorized denomination) that the amount of
such maturity bears to the aggregate principal amount of all Outstanding Bonds, or, at the option
of the Company, the particular Bonds or portions thereof to be redeemed shall be selected by the

lot or by such other random means as the Trustee shall determine in its discretion.

Fund following the completion of the Project.

redemption by the Issuer prior to maturity, at a redemption price equal to 100% of the principal
amount thereof, together with accrued interest to the date of redemption, upon a Determination of

     9. Prepayment of Bonds. No Bond may be called for redemption prior to its stated
maturity except as provided in the Loan and Trust Agreement; provided, however, that nothing in the

prior to maturity shall be given by mailing a copy of the redemption notice by first-class mail not
less than 30 nor more than 60 days prior to the Redemption Date to the Bondowner of each Bond to be
redeemed at the address shown on the Bond Register; provided, however, that failure to give any

A-5

 

such notice as aforesaid or any defect therein with respect to any particular Bond shall not affect
the validity of any proceedings for the redemption of any other Bond.

redeemed (including, at a minimum, certificate numbers and called amount for each certificate (for
partial calls), publication date, Redemption Date, redemption agent name and address, date of
issue, interest rate, maturity date, and other descriptive information, if any, that accurately
identifies the particular Bonds called for redemption), (ii) identify the provisions of the Loan
and Trust Agreement pursuant to which the Bonds are being redeemed, (iii) identify the place of
payment, (iv) state the applicable redemption price, including the premium, if any, and (v) state

of and premium, if any, on the Bonds or portions thereof thus called for redemption and to pay the
interest thereon to the Redemption Date, such Bonds or portions thereof shall cease to bear
interest from and after the Redemption Date in question.

of the Bonds shall have no right to enforce the provisions of the Loan and Trust Agreement or to
institute action to enforce the covenants therein, or to take any action with respect to any event

other proceedings with respect thereto. In certain events, on the conditions, in the manner and
with the effect set forth in the Loan and Trust Agreement, the principal of all Bonds issued under
the Loan and Trust Agreement and then outstanding may become or may be declared due and payable

Bond, and the Issuer shall issue, and the Trustee shall authenticate, one or more new Bonds of

registered owner hereof as the absolute owner hereof for the purpose of receiving payment of or on
account of the principal of, premium, if any, and interest due hereon and for all other purposes,
and neither the Issuer, nor the Trustee nor any alternate paying agent shall be affected by any
notice to the contrary.

SERIES 2006

PROMISSORY NOTE

          This Promissory Note (“Note”) made and entered into as of the 27th day of April,
2006, by and among Advanced BioEnergy, LLC, a Delaware limited liability company (the “Company”) as
debtor, and the County of Fillmore, in the State of Nebraska, duly existing under the laws of the
State of Nebraska (the “Issuer”), and Wells Fargo Bank, N.A., as assignee of the Issuer (the
“Trustee”); witnesseth:

          The Company, for value received, promises to pay the Trustee, as trustee under the Loan and
Trust Agreement dated as of April 1, 2006 (the “Agreement”), executed by the Issuer the principal
sum of $7,000,000 in monthly installments, together with interest thereon at the rates on the
Series 2006A Bonds, as hereinafter defined, in amounts as follows:

          A. In immediately available funds before 10:00 a.m., Lincoln, Nebraska time on the first day
of each month or, if not a business day, the next succeeding business day after the first day of
each month, 1/6th of the interest due on the next Payment Date as defined in the
Agreement.

          B. Commencing on December 1, 2009, in immediately available funds before 10:00 a.m., Lincoln,
Nebraska time on the first day of each month or, if not a business day, the next succeeding
business day after the first day of each month, 1/12th of the principal payable on the
next Payment Date on which principal is payable, as defined in the Agreement.

          All payments of principal, prepayment premium, if any, interest, or any other amounts
hereunder shall be made to the Trustee at its principal office in lawful money of the United States
of America.

          In the event the Company should fail to make payment of any such installment of principal or
interest when due, the amount so in default shall continue as an obligation of the Company until
the amount in default shall have been fully paid, and the Company agrees to pay the same with
interest thereon at the stated rate plus 3 percent per annum until paid.

          Concurrent with the execution and delivery of this Note, the Issuer has issued $7,000,000
principal amount of its County of Fillmore in the State of Nebraska Subordinate Exempt Facilities
Revenue Bonds, Series 2006A (Advanced BioEnergy, LLC Ethanol Plant Project) under the Agreement
(the “Bonds”).

          All of the proceeds from the Bonds are to be used to finance the Project as defined in the
Loan and Trust Agreement.

          So long as there is no Event of Default subsisting hereunder, each payment of the
Company under this Note shall be applied to a payment of principal of, or premium, if default
hereunder, payments by the Company on this Note or the Additional Notes shall be used to make

 

 

payments on the principal of, premium if any, or interest on the Bonds as required by the
Agreement.

          The terms of this Note, with the exception of the monthly payment provision, are identical
with the terms of the Bonds as to principal payment dates and amounts, interest rates, and
prepayment or redemption provisions. Notwithstanding anything herein to the contrary, in order to
allow the Paying Agent to be able to pay the principal of and interest on the Bonds, when due,
Company agrees and promises that all principal and interest payments to be made under the first
paragraph of this Note shall be made at such time and in such manner so that the Paying Agent will
have collected funds in an amount equal to such payment on the business day that such payments are
stated to be due under the first paragraph of this Note; and payments of principal of, premium, if
any, and interest on the Bonds with moneys in the Bond Account (as defined in the Agreement) from
any source described in the Agreement shall be deemed to be like payments by the Company hereunder.

          This Note is secured by a Subordinate Deed of Trust and Construction Security Agreement on the
Facilities and the Project (as defined in the Agreement) which is a lien on the Facilities and the
Project (as defined in the Agreement) and property located on or to be located on the Facilities
located within or near Fairmont, Nebraska and other properties.

          This Note is prepayable in the event that the Company shall exercise its option to prepay this
Note as provided in the Agreement. In such event, this Note shall be subject to prepayment by the
Company at any time in whole or in part at the prepayment prices applicable to the portion of the
Bonds to be redeemed by the exercise of the option.

          The Company shall give the Issuer and the Trustee such notice of any optional prepayment of
this Note as shall enable the parties to take all action necessary under the Agreement to redeem on
the date specified for prepayment of an identical principal amount of the Bonds. Upon receipt of
notice from the Company specifying the amount and date of prepayment, the parties shall take all
action necessary under the Agreement to redeem on the prepayment date the Issuer’s Bonds in an
amount corresponding to that specified in the notice. Failure by the Issuer or the Trustee to take
such action shall void the right of the Company to prepay all or a portion of this Note on the
prepayment date specified.

          Whenever payment or provision therefore has been made in respect to the principal of (whether
at maturity or upon redemption or acceleration), premium, if any, or interest on, all or any
portion of the Bonds in accordance with the Agreement, this Note shall be deemed paid to the extent
such payment or provision therefor has been made and is considered to be a payment of principal of,
premium, if any, or interest on, the Bonds. If the Bonds are thereby deemed paid in full, this
Note shall be canceled and returned to the Company. Subject to the foregoing or unless the Company
is entitled to a credit under the Agreement, all payments shall be in the full amount required
under this Note.

          The obligations of the Company to make the payments required hereunder shall be
absolute and unconditional without defense or set-off by reason of any default by the Issuer under
the

2

 

Agreement, the Deed of Trust, or under any other agreement between the Company and the Issuer
or for any other reason, including without limitation, any acts or circumstances that may
constitute failure of consideration, eviction, or constructive eviction, destruction of or damage
to the Project or Facilities, commercial frustration of purpose, any change in the tax or other
laws or administrative rulings of or administrative actions by the United States of America or the
State of Nebraska or any political subdivision of either, or any failure of the Issuer to perform
and observe any agreement, whether express or implied, or any duty, liability, or obligation
arising out of or connected with the Agreement or the Deed of Trust, it being the intention of the
Company and the Issuer that the payments hereunder will be paid in full when due without any delay
or diminution whatsoever.

          Subject to the Subordination Agreement, in case one or more of the Events of Default specified
in the Agreement or the following shall have occurred and be continuing:

     (a) Failure by the Company to pay when due an amount required to be paid under this
Note, or any Additional Notes at the time specified therein as a consequence of optional or
mandatory prepayment or acceleration; or

     (b) Failure by the Company to pay when due any amounts required to be paid under this
Note, or any Additional Notes at the times specified therein, other than as referred to in
(a) above, and continuing for a period of two (2) business days;

then and in each and every such case, the Trustee, by notice in writing to the Company, may declare
the unpaid balance of this Note to be due and payable immediately, if concurrent with or prior to
such notice, the unpaid principal amount of the Bonds has been declared to be due and payable, and
upon any such declaration the same shall become and shall be immediately due and payable to the
extent permitted by the Subordination Agreement.

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

          The Company covenants that in case an Event of Default shall occur with respect to the payment
of any installment of principal, premium, if any, interest, or any other amount due in respect to
this Note, whether at maturity or upon prepayment or by acceleration or otherwise, then, upon
demand of the Trustee the Company will pay to the Trustee the whole amount that then shall become
due and payable on this Note for principal, premium, if any, interest or any other amount due
hereunder as the case may be, with interest from the date due at the stated rate plus 3 percent per
annum, and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including a reasonable compensation to the Trustee, its agents, attorneys,
and counsel, and any expenses or liabilities incurred by the Trustee.

3

 

          In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee
shall be entitled and empowered to institute any action or proceeding at law or in equity for the
collection of the sums so due and unpaid, and may prosecute any such action or proceeding to
judgment or final decree, and may enforce any such judgment or final decree against the Company and
collect, in the manner provided by law, out of the property of the Company, the moneys adjudged or
decreed to be payable.

          In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company under the federal bankruptcy laws or any other applicable law, or in case a receiver or
trustee shall have been appointed for the property of the Company or in the case of any other
similar judicial proceedings relative to the Company, or to the creditors or property of the
Company, the Trustee shall be entitled and empowered, by intervention in such proceedings or
otherwise, to file and prove a claim or claims for the whole amount of principal, prepayment
premium, if any, and interest owing and unpaid in respect of this Note and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may be necessary or
advisable in proceedings relative to the Company, its creditors, or its property, and to collect
and receive any moneys or other property payable or deliverable on any such claims, and to
distribute the same after the deduction of its charges and expenses; and any receiver, assignee, or
trustee in bankruptcy or reorganization is hereby authorized to make such payments to the Trustee
any amount due it for compensation and expenses, including counsel fees incurred by it up to the
date of such distribution.

          This Note shall be governed by and construed in accordance with the laws of the State of
Nebraska.

          IN WITNESS WHEREOF, the Company has caused this Note to be duly executed and delivered as of
this 27th day of April, 2006.
